This study used tagged magnetic resonance imaging (MRI) to measure left ventricular (LV) twist in different layers of the heart (endocardium, mid-wall, and epicardium) in 52 healthy subjects ranging from 21 to 82 years old. The study found that LV twist increases with age and is greatest in the endocardial layer and lowest in the epicardial layer for all age groups. Measuring LV twist using tagged MRI provides more accurate analysis compared to 2D speckle tracking echocardiography, as tagged MRI is not affected by out-of-plane motion and allows full volume analysis of the heart in 3D.
Correlation Between ECG Changes and 2D Speckle Tracking Echocardiography with...Premier Publishers
The clinical presentation of acute coronary syndrome is variable Patients with suspected NSTE-ACS are a heterogeneous group. Coronary occlusion may or may not be present. To correlate 2D speckle tracking echocardiography with coronary angiography results in non-ST segment elevation myocardial infarction patients and test its ability to predict culprit lesion. It is a prospective study where 100 patients with non-ST elevation myocardial infarction were enrolled in the study where regional wall motion score index was obtained by echocardiography then 2D speckle tracking echocardiography was done and territorial longitudinal strain for each vessel was obtained and finally coronary angiography was done. By using the bull’s eye view of the territorial LS values obtained from the 17 myocardial segments to predict the culprit artery for each patient the sensitivity for prediction of culprit LAD was 93.3 %, specificity was 92.7 %, For LCX; sensitivity was 82.7 %, specificity was 92.9 % and for RCA; sensitivity was 84 %, specificity was 93.3 %. Longitudinal strain imaging by 2D speckle-tracking might help in the work-up of non-ST elevation myocardial infarction patients. In addition, it may be helpful to localize coronary artery stenosis in a given perfusion territory.

Early Detection of Left Ventricular Dysfunction in Type II Diabetic Patients ...Premier Publishers
To assess Left ventricular (LV) systolic dysfunction using 2D speckle tracking echocardiography (STE) in asymptomatic type II Diabetic patients. We acquired three LV short-axis, and three LV apical views in 100 asymptomatic diabetic patients with normal LV ejection fraction (EF) and 25 age-matched healthy volunteers. We measured end-systolic longitudinal strain (LS), radial strain (RS), and circumferential strain (CS) in 18 LV segments. There were no significant differences in LVEF between two groups. Diabetic patients had more advanced diastolic dysfunction and increased LV mass compared with controlled group. Basal, middle, and apical LSs were significantly lower in diabetic patients compared with control subjects, with 43% (43/100) of the diabetic patients showing abnormal global LS values (cut-off value: 217.2 mean 2SD in control subjects Conclusion: Detecting subclinical LV systolic dysfunction by using 2D speckle tracking echocardiography (STE) might provide useful information of the risk stratification in an asymptomatic diabetic population.

CT and MRI of Aortic Valve Disease: Clinical Update Sam Watermeier
This article from Current Radiology Reports explores new improvements in CT and MR imaging techniques, which yield valuable information for patients with a variety of aortic valve and root pathology.
Invasive coronary physiology to select patients for coronary revascularisation has become established in contemporary guidelines for the management of stable coronary artery disease. Compared to revascularisation based on angiography alone, the use of coronary physiology has been shown to improve clinical outcomes and cost efficiency. However, recent data from randomised controlled trials have cast doubt upon
the value of ischaemia testing to select patients for revascularisation. Importantly, 20-40% of patients have
persistence or recurrence of angina after angiographically successful percutaneous coronary intervention
(PCI). This state-of-the-art review is focused on the transitioning role of invasive coronary physiology from
its use as a dichotomous test for ischaemia with fixed cut-points, towards its utility for real-time guidance of PCI to optimise physiological results. We summarise the contemporary evidence base for ischaemia testing
in stable coronary artery disease, examine emerging indices which allow advanced physiological guidance
of PCI, and discuss the rationale and evidence base for post-PCI physiological assessments to assess the success of revascularisation.
The optimal management of bifurcation lesions has received significant interest in recent years and remains a matter of debate among the
interventional cardiology community. Bifurcation lesions are encountered in approximately 21% of percutaneous coronary intervention procedures
and are associated with an increased risk of major adverse cardiac events. The Medina classification has been developed in an attempt to
standardise the terminology when describing bifurcation lesions. The focus of this article is on the management of the Medina 0,0,1 lesion
(‘Medina 001’), an uncommon lesion encountered in <5% of all bifurcations. Technical considerations, management options and interventional
techniques relating to the Medina 001 lesion are discussed. In addition, current published data supporting the various proposed interventional
treatment strategies are examined in an attempt to delineate an evidence-based approach to this uncommon lesion.
BACKGROUND
Pulmonary artery-to-left atrium fistula is a variant of pulmonary arteriovenous fistula and is a developmental anomaly. Delayed presentation, cyanosis and effort intolerance are some of the important features. The diagnosis is confirmed by computed tomography or pulmonary artery angiography. Catheter-based closure is preferred to surgery.
CASE SUMMARY
Left pulmonary artery-to-left atrium fistula is rare. A 40-year-old male presented with effort intolerance, central cyanosis, and recurrent seizures. He had a large and highly tortuous left pulmonary artery-to-left atrium fistula associated with a large aneurysmal sac in the course. Catheter-based closure was performed using a vascular plug.
CONCLUSION
Left pulmonary artery-to-left atrium fistula is relatively uncommon compared to right pulmonary artery-to-left atrium fistula. Percutaneous closure by either a transeptal technique or guide wire insertion into the pulmonary vein through the pulmonary artery is preferred. The need for an arteriovenous loop depends on the tortuosity of the course of the fistula and the size of the device to be implanted because a larger device needs a larger sheath, necessitating firm guide wire support to facilitate negotiation of the stiff combination of the delivery sheath and dilator.

Assessment of Intermediate Coronary Artery Lesion with Fractional Flow Reserv...Premier Publishers
Fraction flow reserve (FFR) is considered the gold standard for assessing intermediate coronary lesions. Retrospective data analyses showed variable relationship between intravascular ultrasound (IVUS) parameters and FFR results. This study aimed to determine the optimal minimum lumen area (MLA) by IVUS that correlates with FFR and to assess the correlation between two modalities in assessing intermediate coronary lesions. Methods: Fifty eight intermediate coronary lesions mainly located in proximal and mid segments of large main coronary vessels with RVD (3-4mm) were analyzed using both IVUS and FFR to assess the significance of coronary stenting and to determine the optimal IVUS-MLA that correlates with FFR value < 0.8. Results: IVUS-MLA ranged from 2.5 to 4.2 mm2 had a highly significant positive correlation with FFR value < 0.8 (p < 0.0001). Using the ROC curve analysis, IVUS-MLA < 3.9 mm2 (84.2% sensitivity, 80% specificity, area under curve (AUC) = 0.68) was the best threshold value for identifying FFR <0.8>< 0.8 in coronary vessels with RVD (3-4mm). Different MLA cutoffs should be used for different vessel diameters.
Role of Left Ventricular Mass Index Versus Left Ventricular Relative Wall Thi...Premier Publishers
In non-cardioembolic stroke patients, the cardiac manifestations of elevated blood pressure are of particular interest. The value of LV geometry in the prediction of cardiovascular risk is controversial. Many reports detected that left ventricular hypertrophy is independently associated with risk of ischemic stroke. The primary objective of this study was to identify the frequency of different patterns of altered left ventricular geometry in patients with non cardioembolic stroke, and to assess whether a significant number of patients will miss the diagnosis of LV remodeling if the left ventricular relative wall thickness(RWT) is not evaluated or reported. 100 patients were referred within 48 hours after an acute non cardioembolic ischemic stroke for a transthoracic echocardiogram. The echocardiographic findings were analyzed. Mean age was 61.86 ± 12.59 years, 45 % men. Concentric remodeling carried the highest frequency (43%), followed by normal pattern (27%), concentric hypertrophy (22%), and eccentric hypertrophy (8%). The frequency of abnormal left ventricular RWT (61.4%) was significantly higher than that of abnormal LVMI.
Coronary angioplasty has revolutionized the management of coronary artery disease. It has not ceased to develop to become the reference method of myocardial revascularization. The aim of our study is to evaluate the ultrasound parameters of left ventricular function after coronary angioplasty. This is a prospective analytical study including patients with stable coronary artery disease with a known coronary artery anatomy programmed for coronary angioplasty. Transthoracic echocardiography was performed four hours before and seven days after myocardial revascularization.

A Speckle Tracking Echocardiographic Study for Correlation Between Global Lef...Premier Publishers
Global longitudinal strain (GLS) measured by Two-dimensional speckle tracking imaging (2D-STI) has been shown to be useful for assessing subtle changes in the left ventricular function with increasing severity of aortic stenosis (AS) in patients with preserved left ventricular ejection fraction (LVEF). To evaluate the relation between the severity of valve stenosis and GLS measured by 2D-STI in AS patients with normal LVEF. We studied 65 subjects (age, 53_75 years) with normal LVEF (≥50%) but without overt coronary artery disease. Patients were stratified into four groups (control, mild, moderate and severe AS), the clinical characteristics and echocardiographic findings were compared among the groups. Using dedicated software, we measured GLS in the apical four, two and three -chamber views. LVEF was not significantly different among the four groups. However, GLS showed significant differences among the four groups (controls;18.9±1.4, mild: 18.8±1.3, moderate: 15.35±1.6and severe: 12.42±1.4, ANOVA P = 0.001), GLS was significantly correlated with AVA, mean PG and LV mass index. Despite unchanged LVEF, GLS gradually decreased as severity of AS increases. GLS measured by 2D-STI is useful to assess subtle changes in LV function in AS patients.

Unlike other modalities, MRI offers the capability to modulate both the emitted and received signals so that a multitude of tissue characteristics can be examined and differentiated without the need to change scanner hardware.
As a result, from a single imaging session, one could obtain a wealth of information regarding
cardiac function and morphology,
myocardial perfusion & viability,
hemodynamics,
large vessel anatomy.
CMR is now considered the gold standard for the assessment of regional and global systolic function, myocardial infarction (MI) and viability, and the assessment of congenital heart disease.

Thermal Imaging for the Diagnosis of Early Vascular Dysfunctions: A Case Reportasclepiuspdfs
Diseases of blood vessels (referred in this article as vascular dysfunction) cause more morbidity and mortality, than combined impact of any other major non-communicable disease including cancer. We strongly feel that the development of a therapy system based on the management of disease of the vessel than management of the risk factors will yield better results and provide greater opportunity for individualized therapy. Detection of early vascular changes before clinical manifestations of endothelial dysfunction, hardening of the arteries, increased intima-media thickness, is of great importance for early identification of individuals with increased risk of accelerated atherosclerosis.

At SciArt Center, we think artists and scientists seek answers to the same fundamental questions: who are we, why are we here, and where are we going? Both art and science build models of human experience in order to extend the boundaries of human capacity. Despite this common ground, artists and scientists are too often separate in their endeavors. As a community-based arts organization, we provide support and promote cross-disciplinary approaches and interactions.
SciArt Center offers a variety of online resources for our members and also hosts an assortment of pop-up events around New York City open to the public. In creating a virtual space for our members to interact and share their work, we seek to connect scientists and artists online and explore the potentials of those connections. Paired with our partner publication SciArt in America, we publish the fruits of these cross-disciplinary interactions, bolstering the science-art community at large. Our science and art themed pop-up events including film screenings, book club meetings, art shows, panel talks, and social mixers, serve to physically bring together scientists and artists for a common creative and intellectual cause.
With the pursuit of scientific and artistic understanding within the larger paradigm of intellectual unity, SciArt Center encourages the connectivity and transdisciplinary approaches needed for the 21st century.

Aims: Post-mortem pathological studies have shown that a “vulnerable” plaque is the dominant patho-physiological mechanism responsible for acute coronary syndromes (ACS). One way to improve our understanding of these plaques in vivo is by using histological “surrogates” created by intravascular ultrasound derived virtual histology (IVUS-VH). Our aim in this analysis was to determine the relationship between site-specific differences in individual plaque areas between ACS plaques and stable plaques (SP), with a focus on remodelling index and the pattern of calcifying necrosis.
Methods and results: IVUS-VH was performed before percutaneous intervention in both ACS culprit plaques (CP) n=70 and stable disease (SP) n=35. A total of 210 plaque sites were examined in 105 lesions at the minimum lumen area (MLA) and the maximum necrotic core site (MAX NC). Each plaque site had multiple measurements made including some novel calculations to ascertain the plaque calcification equipoise (PCE) and the calcified interface area (CIA). CP has greater amounts of positive remodelling at the MLA (RI@MLA): 1.1 (±0.17) vs. 0.95 (±0.14) (P<0.001);><0.001)>1.12; RI @ MAX NC >1.22; PCE @ MLA <47.1%;><47.3%;>2.6; CIA @ MAX NC >3.1.
Conclusions: Determining the stage of calcifying necrosis, along with the remodelling index can discriminate between stable and ACS related plaques. These findings could be applied in the future to help detect plaques that have a vulnerable phenotype.
Echocardiographic guidance is critical for procedural success of paravalvular leak closure. Transesophageal echocardiography (TEE) and particularly three-dimensional echocardiography represent the gold standards. Fusion imaging provides real-time integration of three-dimensional echocardiography and X-ray fluoroscopy and can further facilitate spatial orientation, wire placement and device deployment. Intracardiac echocardiography (ICE) is a secondary approach possibly beneficial in selected cases.
Prosthetic paravalvular leaks (PVL) is an uncommon but serious complication after surgical valve replacement. Although surgery has been the traditional treatment of choice in hemodinamically significant PVL, percutaneous transcatheter closure is emerging as a novel and less invasive option for patients with high operative risk. Cardiac imaging, especially two- and three-dimensional transoesophageal echocardiography, plays an essential role in the diagnosis, guidance of intervention and subsequently in the evaluation of the outcomes of the procedure. The aim of this manuscript is to review the role of cardiac imaging techniques in the interventional management of patients with symptomatic PVL.
Background: Myocarditis is a relatively common inflammatory disease that affects the myocardium. Infectious disease accounts for most of the cases either because of a direct viral infection or post-viral immune-mediated reaction. Cardiovascular magnetic resonance (CMR) has become an established non-invasive diagnosis tool for acute myocarditis. A recent large single centre study with patients with biopsy-proven viral myocarditis undergoing CMR scans found a high rate of mortality. The aim of this study was to assess the rate of clinical events in our population of patients with diagnosed myocarditis by CMR scan.
Methods: Patients who consulted to the emergency department with diagnosis of myocarditis by CMR were retrospectively included in the study from January 2008 to May 2012. A CMR protocol was used in all patients, and were followed up to assess the rate of the composite endpoint of all-cause death, congestive heart failure, sudden cardiac death, hospitalization for cardiac cause, recurrent myocarditis or need of radiofrequency ablation or implantable cardiac defibrillator (ICD). A descriptive statistical analysis was performed.
Results: Thirty-two patients with myocarditis were included in the study. The mean age was 42.6±21.2 years and 81.2% were male. In a mean follow up of 30.4±17.8 months, the rate of the composite endpoint of all-cause death, congestive heart failure, sudden cardiac death, hospitalization for cardiac cause, recurrent myocarditis or need of radiofrequency ablation or ICD was 15.6% (n=5). Two patients had heart failure (one of them underwent heart transplant), one patient needed ICD because of ventricular tachycardia and two other patients were re-hospitalized, for recurrent chest pain and for recurrent myocarditis respectively.
Conclusions: In our series of acute myocarditis diagnosed by CMR we found a low rate of cardiovascular events without mortality. These findings might oppose data from recently published myocarditis trials.
Abstract
This issue of ‘Cardiovascular Diagnosis and Therapy (CDT)’ has a special focus on application and development of magnetic resonance imaging (MRI) in cardiovascular diseases. The challenges associated with imaging of the heart and the huge disease burden associated with cardiovascular diseases has been one of the major motivations in the last few years for the development of new MRI techniques. A realm of new pulse sequences, either focusing on ‘freezing’ motion or on providing improved endogenous contrast mechanisms were developed in this context and are now being evaluated in clinical and preclinical research efforts focusing on the heart and vascular circulation.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
