Definition: Cardiac arrhythmias refer to abnormal heart rhythms, where the heartbeat may be too slow (bradycardia), too fast (tachycardia), or irregular.
These irregularities disrupt the normal electrical signaling in the heart.
In a world where hearts beat free and bold,
A silent foe creeps, its story untold,
Rheumatic whispers, in hushed refrain,
A tale of love's struggle, of heartache and pain.
A childhood song, innocent and sweet,
Takes a tragic turn, hearts skip a beat,
Rheumatic winds blow, fierce and unseen,
Leaving scars on hearts that once danced so keen.
Valves that should open, a rhythmic embrace,
Now bear the weight of this silent chase,
Rheumatic echoes, a haunting refrain,
Leaving imprints of sorrow, of loss and of pain.
But amidst the shadows, there's hope that glows,
A symphony of care, compassion bestows,
With knowledge and love, we stand side by side,
To mend these hearts, to be a healing guide.
Rheumatic battles, we'll face them anew,
A united front, a relentless crew,
For every heart deserves freedom's embrace,
And in the face of rheumatic storms, we'll find grace.
So let's raise our voices, let the world hear,
The fight against rheumatic pain, we hold dear,
With courage and faith, we'll rewrite the verse,
A tale of triumph, of hearts that converse.
"Rheumatic fever reminds us that our body is a delicate symphony, and neglecting even the slightest discord can lead to profound consequences." -
"In the battle against rheumatic fever, awareness and early intervention are our most potent allies."

5. A 5 years old boy presents with fever & swelling of knee and ankle joint for 3 weeks. Write down 3 important D/D. Discuss the treatment of acute rheumatic fever with carditis. (DU-09Ju)
Three important differential diagnoses of a 5-year-old boy presenting with fever and joint swelling for 3 weeks include:
Septic arthritis: This is an acute bacterial infection of a joint that causes similar symptoms to rheumatic fever but is usually monoarticular and associated with more severe pain, redness, and tenderness of the affected joint. Septic arthritis requires urgent drainage and antibiotics.
Juvenile idiopathic arthritis: This is a group of chronic autoimmune disorders that can present with fever, joint swelling, and stiffness. The diagnosis is based on clinical features, laboratory tests, and imaging studies. The treatment may include nonsteroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs, and biologic agents.
Reactive arthritis: This is an inflammatory joint disease that can occur after an infection, especially with certain bacteria such as Chlamydia, Salmonella, or Shigella. Reactive arthritis usually affects the lower limb joints, such as knees, ankles, and feet, and may be associated with skin rash, eye inflammation, or urethritis. The treatment may include antibiotics, nonsteroidal anti-inflammatory drugs, and corticosteroids.
Assuming the diagnosis of acute rheumatic fever with carditis, the treatment usually involves a combination of antibiotics and anti-inflammatory drugs. The antibiotics aim to eradicate the streptococcal infection and prevent further rheumatic fever recurrences, while the anti-inflammatory drugs aim to reduce the inflammation and symptoms of carditis. The specific regimen may vary depending on the severity of carditis, the presence of other complications, and the patient's age and weight. In general, the following principles apply:
Antibiotics: A 10-day course of oral or intramuscular penicillin is the first-line antibiotic for acute rheumatic fever, as it is effective against most strains of streptococci and has low toxicity. Alternative antibiotics may be used for patients who are allergic to penicillin or have recurrent rheumatic fever despite adequate penicillin therapy. Long-term prophylaxis with penicillin is recommended to prevent recurrences, usually until the age of 21 years or for 10 years after the last episode of rheumatic fever, whichever is longer.
Anti-inflammatory drugs: High-dose aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen are usually given for the first 2-3 weeks of acute rheumatic fever to control fever, pain, and inflammation. Corticosteroids such as prednisone or methylprednisolone may be used in severe cases of carditis or when other therapies are not effective or contraindicated. The duration and dose of anti-inflammatory drugs should be tailored to the patient's response and adverse effects, such as gastric
The Cardiovascular System: Life's Vital Transport System
The cardiovascular system, comprising the heart, blood vessels, and blood, is a fundamental physiological network in the body.
It facilitates the circulation of oxygen, nutrients, hormones, and immune cells while eliminating waste products.
Essential for maintaining tissue function, energy production, and overall homeostasis.
Defining the Cardiovascular System
The cardiovascular system, also known as the circulatory system, is a complex network responsible for circulating vital substances throughout the body.
Components of the Cardiovascular System
Heart: A muscular organ that pumps blood, generating the force required to propel blood through the blood vessels.
Blood Vessels: A network of tubes that carry blood to and from various body tissues.
Blood: A specialized fluid containing red and white blood cells, platelets, and plasma, essential for nutrient and gas exchange.
Exploring Applied Physiology of the Cardiovascular System
The cardiovascular system is a cornerstone of human health, regulating the circulation of vital nutrients, oxygen, and waste products throughout the body.
Understanding the applied physiology of this system is essential for healthcare professionals to provide effective medical care and interventions.
Importance of Applied Cardiovascular Physiology
Effective healthcare requires a deep comprehension of how the cardiovascular system functions under various conditions.
Applied physiology knowledge empowers healthcare practitioners to make informed decisions, diagnose disorders, and formulate targeted treatment plans.
Focus on Practical Applications in Healthcare
This presentation delves into the practical aspects of cardiovascular physiology that directly impact clinical practice.
We will explore how physiological concepts are translated into real-world medical scenarios and interventions.
By grasping the applied physiology of the cardiovascular system, healthcare providers can optimize patient care, enhance diagnostics, and improve treatment outcomes.
Throughout this presentation, we'll bridge the gap between theoretical understanding and its practical implications in the field of healthcare.
Understanding the Components
The cardiovascular system comprises three crucial components: the heart, blood vessels, and blood.
Heart: A muscular organ that pumps blood, ensuring a continuous flow throughout the body.
Blood Vessels: A network of tubes that transport blood to and from various tissues.
Blood: A specialized fluid that carries nutrients, oxygen, hormones, and removes waste products.
Role in Oxygen and Nutrient Delivery
Oxygen from the lungs and nutrients from the digestive system are transported to body tissues through the bloodstream.
These essential components are required for cellular metabolism and energy production.
Peripartum cardiomyopathy (PPCM) is a type of heart disease that affects women during the last month of pregnancy or in the first few months after delivery. It is characterized by a weakened and enlarged heart muscle, which makes it difficult for the heart to pump blood efficiently to the rest of the body. The exact cause of PPCM is unknown, but it is believed to be related to the hormonal changes and increased demands on the heart that occur during pregnancy. Symptoms of PPCM can include shortness of breath, fatigue, chest pain, swelling in the legs and feet, and palpitations. Treatment for PPCM usually involves medications to improve heart function and supportive care to manage symptoms. In severe cases, advanced treatments such as implantable devices or heart transplantation may be necessary. With early diagnosis and treatment, most women with PPCM can recover completely and go on to lead healthy lives.during pregnancy.
The diagnosis of PPCM is based on clinical symptoms, such as shortness of breath, fatigue, chest pain, and edema, along with imaging studies, such as echocardiography. Treatment for PPCM usually involves medications to improve heart function and supportive care to manage symptoms. These medications can include beta-blockers, ACE inhibitors, diuretics, and inotropic agents. In severe cases, advanced treatments such as mechanical circulatory support or heart transplantation may be necessary.
The prognosis for PPCM varies depending on the severity of the disease and the presence of underlying comorbidities. However, with early diagnosis and appropriate treatment, most women with PPCM can recover completely and go on to lead healthy lives. The recurrence rate of PPCM in subsequent pregnancies is approximately 20%, and women who have had PPCM are advised to avoid future pregnancies or undergo careful monitoring and management during pregnancy.
There are still many unanswered questions about PPCM, including its exact cause, optimal diagnostic and treatment strategies, and long-term outcomes. Further research is needed to better understand this complex and potentially life-threatening condition.
In conclusion, PPCM is a rare but serious form of heart disease that can occur during or after pregnancy. Early recognition and management of this condition are critical in preventing complications and improving outcomes for both the mother and the baby. Future research will continue to shed light on the pathophysiology and optimal management of PPCM.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

3. Normal valve function
•Maintain forward flow and prevent
reversal of flow.
•Valves open and close in response to
pressure differences (gradients) between
cardiac chambers.

9. Abnormal valve function
•Valve Stenosis
•Obstruction to valve flow during that phase of the
cardiac cycle when the valve is normally open.
•Hemodynamic hallmark -“pressure gradient”
•Valve Regurgitation, insufficiency, incompetence
•Inadequate valve closure → reverse flow of the blood,
back leakage
•Combined – a single valve can be both stenotic and
regurgitant; combinations of valve lesions can coexist
•Single disease process
•Different disease processes
•One valve lesion may cause another
•Certain combinations are particularly common(AS & MR,
MS & TR)
17. History
• Generally: symptoms of heart failure
and low cardiac output
• Breathlessness
• Chest pain or dyscomfort
• Syncope
• Fatigue
• Peripheral or pulmonary oedema
• Palpitations
drtoufiq1971@gmail.com
18. Physical examination
• MURMURS!!!
• Periferal oedema
• Lung crackles
• Elevated JVP
• Displaced apex beat,
irregular heart beat…
Hundreds of eponymous signs from past
millenium (↓importance in daily
routine, ↑importance for passing exam)
19. Heart murmurs
•Sounds produces by turbulent
blood flow (in valve diseseses,
artery stenosis, abnormal
chamber or AVcommunication)
•Localization,grade,
propagation, timing, quality
20. Heart murmurs
Intensity Description
Grade I/VI Barely audible
Grade II/VI Audible, but soft
Grade III/VI Easily audible
Grade IV/VI Easily audible, associated with a thrill
Grade V/VI Easily audible, associated with a thrill, and still audible with the
stethoscope onlylightly on the chest
Grade VI/VI Easily audible, associated with a thrill, and still audible with the
stethoscope off of the chest
drtoufiq1971@gmail.com
21. ECG
• Not specific
• Findings might be caused or altered by other
concomitant heart disease (hypertensive heart
disease, ischemic heart disease)
• Left ventricular hypertrophy (aortic valve
disease)
• Left atrial enlargement (mainy MS, but any left
heart valve disease)
• Atrial fibrilation
• Bundle branch block
• Arrytmias (atrial fibrilation, ectopic beats)
22. Chest x-ray in valvular disease
• Different heart shapes in different valvular
heart diseses, ↓specificity, ↓significance
• Cardiomegaly, pulmonary congestion
• Widened mediastinum
• Valve calcifications, prosthetic valves
23. Echocardiography
• Mainstay of valve disease
diagnosis and follow-up
• Allows real-time measurement of
chamber and wall diameters,
ejection fraction assessment and
functional valve evaluation
• Easily avaiable and repeated
• Essential in acute valve disease
diagnosis
• No radiation harm
• Trans-esophageal echocardiography
avaiable for patients with poor
transthoracic sonographic window
24. Invasive evaluation, CT, MRI
• Methods usualy used for uncertain cases or repeat
cardiac surgery / percutaneous inteventions planning
• Angiography to assess regurgitation severity – direct
transcatheter contrast medium administration into
heart chambers – aortography, ventriculography
• Hemodynamic measurment – measuring of
intracardial pressures and gradients
• CT aortography – method of choice in aortic
dissection diagnosis
• CMRI – very precise evaluation of cardiac tissues and
function, but expensive, low avaiability, long
examination time

26. Aortic regurgitation
• Causes
• Chronic aortic regurgitation
• Bicuspid aortic valve
• Rheumatic and degenerative – always with some
degree of stenosis
• Aortic root dilation (hypertension, Marfan’s,
Ehlers-Danlos, syphylitic aortopathy)
• Other rare causes (SLE, RA)
• Acute aortic regurgiation
• Infective endocarditis
• Aortic regurgitation
drtoufiq19711@yahoo.com
27. Aortic regurgitation
• Pathophysiology of chronic aortic regrgitation
• Leakage of blood into LV during diastole due
to ineffective coaptation of the aortic cusps
• Combined pressure and volume overload
• Compensatory Mechanisms: LV dilation, LVH.
Progressive dilation leads to heart failure
• Greatest mass of myocardium in any valve
disease – „cor bovinum“ – over 500g
Aortic regurgitation
drtoufiq19711@yahoo.com
29. Aortic regurgitation
• Presentation
• Dyspnea: exertional, orthopnea,
and paroxsymal nocturnal
dyspnea
• Chest pain
• Fatigue
• Palpitations: due to increased
force of contraction or arrythmias
Aortic regurgitation
drtoufiq19711@yahoo.com
30. •Physical findings (the ones you might find)
• Diastolic blowing murmur at the left sternal border –
might be very discrete. Systolic ejection murmur might
be present due to increased blood flow across the
aortic valve of concomitant valve stenosis
• Wide pulse pressure – caused by diastolic
regurgitation of blood to LV and fast decrease of
diastolic BP – „Corrigan’s pulse“ (160/30 mmHg…)
• Heaving and laterally displaced apex beat – due to
dilated heart with giant stroke volume
Aortic regurgitation

drtoufiq19711@yahoo.com
31. •Physical findings (the ones you might not find…)
• Quincke’s sign - pulsations of nail bed
• Muller’s sign - pulsation of uvula
• De Musset sign - (head nodding in time with
the heart beat)
• Duroziez sign (systolic and diastolic murmurs
heard over the femoral artery when it is
gradually compressed with the stethoscope)
• Austin Flint murmur (apex): Regurgitant jet
impinges on anterior MVL causing it to vibrate

32. Aortic regurgitation
Echocardiographic Evaluation
Assessment of valve morphology: tricuspid, bicuspid,
unicuspid or quadricuspid valve.
• Determination of the direction of the aortic regurgitation jet
in the long-axis view (central or eccentric) and its origin in the
short-axis view (central or commissural).
• Identification of the mechanism, following the same
principle as for mitral regurgitation: normal cusps but
insufficient coaptation due to dilatation of the aortic root
with central jet (type 1), cusp prolapse with eccentric jet (type
2) or retraction with poor cusp tissue quality and large central
or eccentric jet (type 3).
33. Aortic regurgitation
Echocardiographic Evaluation
• Quantification of aortic regurgitation should follow an
integrated approach considering all qualitative, semi-
quantitative and quantitative parameters.
• Measurement of LV function and dimensions. Indexing LV
diameters for body surface area (BSA) is recommended in
patients with small body size (BSA <1.68 m2).
• New parameters obtained by three-dimensional (3D)
echocardiography, tissue Doppler and strain rate imaging
may be useful, particularly in patients with borderline left
ventricular ejection fraction (LVEF), where they may help in
the decision for surgery.
34. Aortic regurgitation
Echocardiographic Evaluation
• Measurement of the aortic root and ascending aorta in the 2-
dimensional (2D) mode at four levels: annulus, sinuses of
Valsalva, sinotubular junction and tubular ascending aorta.
Measurements are taken in the parasternal long-axis view from
leading edge to leading edge at end diastole, except for the aortic
annulus, which is measured in mid systole.
• As it will have surgical consequences, it is important to
differentiate three phenotypes of the ascending aorta: aortic
root aneurysms (sinuses of Valsalva >45mm), tubular ascending
aneurysm (sinuses of Valsalva <40– 45mm) and isolated aortic
regurgitation (all diameters <40mm). The calculation of
indexed values has been recommended to account for body
size.
35. Aortic regurgitation
Echocardiographic Evaluation
• Definition of the anatomy of the aortic valve
cusps and assessment of valve reparability
should be provided by preoperative TOE if aortic
valve repair or a valve-sparing surgery of the
aortic root is considered.
• Intraoperative evaluation of the surgical result
by TOE is mandatory in patients in whom the
aortic valve is preserved or repaired in the
procedure.
36. Aortic regurgitation
• Acute aortic regurgitation
• Caused by a leaflet perforation in infective
endocarditis
• In aortic dissection due to a change in aortic root
geometry – dilation, extensive intimal tear with
prolapse into LVOT and coaptation impairment
• Presentation of acute aortic regurgitation itself is
usually a pulmonary oedema accompanied by
symptoms of the causing pathology
• True emergency – mostly requires immediate cardiac
surgery

38. Aortic regurgitation
Indication for replacement
• Severe aortic regurgitation (EROA – effective
regurgitant orifice area >0,3 cm2)
• Symptomatic
• LV dilates (over 50 mm EDD) or function
decreases (EF < 55%)
• Other indication for surgery
• Acute
• Moderate regurgitation (AVA 1,5-1 cm2 )
• With other indication for surgery
Aortic regurgitation
49. The evaluation of aortic regurgitation requires consideration of
valve morphology and the mechanism and severity of regurgitation,
including careful assessment of aortic dilatation.
• In asymptomatic patients with severe aortic regurgitation, careful
follow-up of symptomatic status and LV size and function is
mandatory.
• The strongest indication for valve surgery is the presence of
symptoms (spontaneous or on exercise testing) and/or the
documentation of LVEF <50% and/or end-systolic diameter >50 mm.
• In patients with a dilated aorta, definition of the aortic pathology
and accurate measurements of aortic diameters are crucial to guide the
timing and type of surgery.
• Aortic valve repair and valve-sparing aortic surgery instead of
aortic valve replacement should be considered in selected cases in
experienced centres.
