  2. 2. FACTS ABOUTFETAL HEART DS
  3. 3. Facts about Fetal Heart 1. THE HEART IS FULLY FORMED BY THE 6TH WEEK..THE LAST STRUCTURE TO BE FORMED IS THE AV VALVES
  4. 4. HEART FACT 2 HEART DEFECTS ARE THE MOST COMMON BIRTH DEFECTS INCIDENCE IS 1 IN 100
  5. 5. HEART FACT 3 HEART DEFECTS ARE NOT PICKED UP ON ULTRASOUND WE DID A STUDY: 100 CONSECUTIVE NEWBORNS WITH DIAGNOSED HEART DEFECTS PRESENTING TO OUR INSTITUTION AVG NO OF ANTENATAL USGS: 4 NO OF PATIENTS OF SUSPECTED HEART DEFECTS ANTENATALLY: 1/100
  6. 6. HEART FACT IFDIAGNOSED ANTENATALLY, THERE ARE SEVERAL ADVANTAGES BY CLOSING EYES THE PROBLEM DOES NOT GO AWAY PREPARATION AND MORE INFORMATION MANY TIMES ONLY REASSURES PARENTS AFTER INITIAL SURPRISE
  7. 7. FETAL CARDIOLOGY In US 80% cardiac diagnosis made in utero In India almost 100% diagnosis made post natal Devastating diagnosis usually They are not preprared Childs life lost in 30% cases For critical illness: no preparation
  8. 8. INCIDENCE OFHEART DISEASEWHY NOT FETAL ECHO ALLPREGNANCIES ?
  9. 9.  1,75,000 CHILDREN BORN WITH HEART DISEASE IN INDIA EVERY YEAR SO IN 2011 THESE MANY CHILDREN HAVE BEEN BORN AND ADDED TO THE POOL OF KIDS WITH HEART DS IN INDIA OF THESE 30,000 NEED SURGERY IN THE FIRST YEAR BEFORE THEY ARE 1 YR OLD IN INDIA TOTAL PEDIATRIC HEART SURGERIES ARE 10-12,000 PER YEAR AGE 0-18 YR
  10. 10. RECENT LITERATUREA recent review of articles in USA: 30% of antenatal cardiac diagnosis were being picked upon by sonologists Rest by fetal cardiologist The review of this articles asks for more screening for CHD by sonologists

  28. 28. HEART FACT• HEART DEFECTS ARE THE MOST COMMON BIRTH DEFECTS• INCIDENCE IS 1 IN 100
  29. 29. Heart Fact• 1,75,000 children born with CHD each year• 30,000 require surgery before their first birthday otherwise they will not live• Total Pediatric surgeries being done in India not more than 12,000 for 0 to 18 years !!
  30. 30. FETAL CARDIOLOGY• In US 80% cardiac diagnosis made in utero• In India almost 100% diagnosis made post natal• Devastating diagnosis usually• They are not preprared• Childs life lost in 30% cases• For critical illness: no preparation
  31. 31. Clinical Presentation of CHD in theNeonate
  32. 32. Well Baby Exam• A normal neonatal exam definitely does not mean the baby is normal• Infact it does not rule out life threatening CHD’s even those not compatible with life• So, when to suspect CHD in a new born ?
  33. 33. Why Cyanotic CHD is missed at Birth• Cyanosis esp peripheral is not an uncommon finding in newborns• Cyanosis is not always visible to naked eye• Cyanosis on crying is not uncommon in normal newborns• Cyanosis does not become apparent till the duct begins to close
  34. 34. Presentations• Prenatal Diagnosis• Asymptomatic Newborn• Postnatal Cardiac Murmur• Postnatal Critical Illness Presentation: – The Cyanotic Newborn – The Newborn with Respiratory Distress – The Newborn presenting with Shock
  35. 35. SCREENING FOR CHD IN WELLNEWBORNS
  36. 36. Detection of CHD Predischarge• Prior to discharge can we evaluate clinically to detect more pts ?• Can we introduce some screening tools ?• Lets look at how we can detect CHD before their presentation-screening.
  37. 37. The Baltimore-Washington StudyIt was observed that, of all infants with cardiovascular malformations whodied in the first week of life, one infour did not have the cardiovascularmalformation identified before death.Kuehl KS et al. Failure to diagnose congenital heart disease in infancy. Pediatrics 1999;103:743-747
  38. 38. Neonatal Cardiac Mortality• In the best centers, the in-hospital mortality for the arterial switch operation for TGA now approaches 1%.• Death before surgery is becoming proportionally greater: 4% of neonates with TGA died before surgeryArch Dis Child Fetal Neonatal Ed 2001;84:F141-F145
  39. 39. What are the consequences of late missed diagnosis ?• Mortality• Brain Damage• Multiorgan failure• Perioperative mortality
  40. 40. Can we screen for CHD ?• 1990’s: – 4 extremity BP – Palpation of pulses in lower extremity• This was anticipated to help• But still diagnosis was missed• 2000’s – Pulse Oximeter Saturation
  41. 41. Which Cy CHDs will be picked up• If a screening program is started: – IAA – Pulm Atresia – HLHS• Will not be missed• Will get detected before dramatic crash
  42. 42. Screening for duct-dependant congenital heart disease with pulse oximetry: a critical evaluation of strategies to maximize sensitivity• Acta Paediatr. 2005 Nov;94(11):1590-1596.• CTO2 Vs NGO2• 200 normals compared with 66 with critical CHD• IF ONLY ONE MEASUREMENT WAS MADE 7/66 PTS HAD A FALSE NEGATIVE• BUT WHEN CRITERIA WERE CHANGED TO: – > 3% DIFFERENCE BET UL & LL – BOTH UL AND LL SATS < 95%• Then sensitivity of 98.5%, specificity of 96.0%, positive predictive value of 89.0% and negative predictive value of 99.5%
  43. 43. The reliability of a single pulse oximetry readingas a screening test for congenital heart disease in otherwise asymptomatic newborn infants. • Pediatr Cardiol. 2008 Sep;29(5):885-9. • Routine pulse oximetry was neither reliable nor an important diagnostic tool in our cohort.
  44. 44. Strategies for implementing screening for critical congenital heart disease• .• The work-group members found sufficient evidence to begin screening for low blood oxygen saturation through the use of pulse- oximetry monitoring to detect CCHD in well- infant and intermediate care nurseries.• Pediatrics. 2011 Nov;128(5):e1259-67. Epub 2011 Oct 10
  45. 45. NEONATAL PRESENTATIONS• THE BLUE BABY• THE PINK BABY IN DISTRESS• THE SHOCKY BABY
  46. 46. INDICATORS OF CARDIAC PROBLEM PRIMARY SECONDARY • Desaturation • Murmur • Shock • Cardiac Enlargement • Resp Distress • Peripheral Pulse Abn
  47. 47. DESATURATION• PPHN is presumed to be the cause• Surprisingly: CHD can have exactly same presentation• Low saturation without resp cause: r/o cardiac
  48. 48. DIFFERENTIAL DIAGNOSIS• Cyanosis all over – Intracardiac Mixing: Single Ventricle – Intrapulmonary mixing: PPHN• Differential Cyanosis – Upper Limb Blue: TGA+PDA – Lower Limb Blue: Duct Shunting R to L with normally related GA’s• Combination: PPHN – Intrapulmonary + PDA + PFO shunting
  49. 49. THINK CARDIAC WHENTHINKING PULMONARY ESPECIALLY IF ANY OF THE SECONDARY FACTORS PRESENT
  50. 50. INDICATORS OF CARDIAC PROBLEM SECONDARY PRIMARY • Murmur • Desaturation • Cardiac Enlargement • Shock • Peripheral Pulse • Resp Distress Abn
  51. 51. CHD (Obstructive) Vs SEPSIS(HLHS)Coarctation, Aortic Stenosis, Hypopl LV• Most NB’s transferred to tertiary centers are already on ABx• Differentiating Sepsis is very difficult !• Most markers dont have reliable sensitivity• 22/47 such cardiac newborns did not have murmur• Majority with fulminant sepsis had weak pulses due to low cardiac outputDifferentiation of systemic infection and congenital obstructive left heart disease in the very young infant. Pediatr Emerg Care 1998;14:263-267
  52. 52. IN SHOCKY PATIENTS :ALWAYS R/O CARDIAC ESPECIALLY IFSECONDARY SIGNS PRESENT
  53. 53. WITH RESP DISTRESS IN NEONATES: HAVE A LOW THRESHOLD TO SUSPECT CARDIAC LESIONS
  54. 54. HOW TO REACH A DIAGNOSIS ?• SUSPECT: KNOWLEDGE BASE REQUIRED• DIAGNOSTIC MODALITY: ECHOCARDIOGRAM: Ready availability of reliable Bedside Pediatric/Neonatal Echo remains the single most important hurdle in the diagnosis of neonatal CHD
  55. 55. An era is approaching when the time of greatest hazard to the infant is not while under the surgeons knife or in the intensive care unit after surgery, but before actually being admitted to the specialist centerPaediatric intensive care: a framework for the future. London: National Health Service Executive, 1997.
  56. 56. BRIDGE TO TRANSPORT ACRITICALLY ILL CHILD PROSTAGLANDIN
  57. 57. WHO SHOULD BE GIVEN PROSTAGLANDIN • The threshold for starting prostaglandin is directly proportional to severity of the childs illness • In the critically ill child: start Prostin without wasting time • Go by clinical findings
  58. 58. Physical Exam helps in deciding • THE CLINICALLY USEFUL FINDING IS CYANOSIS IN A CRITICALLY ILL NEWBORN: – IF MURMUR+CYANOSIS IS PRESENT START PROSTIN
  59. 59. Physical Exam helps in deciding• The clinically useful finding IN A NON- CYANOSED CRITICALLY ILL NEWBORN IS:• PRESENCE OF ABNORMAL PULES: IF PRESENT START PROSTIN Danford DA et al. Application of information theory to decision analysis in potentially prostaglandin-responsive neonates. JACC 1986;8:1125-1130
  60. 60. STARTING PROSTIN• USUALLY THE DECISION TO START IS EASY IN CRITICALLY ILL “DYING” NEWBORN• RESPONSE IS DRAMATIC
  61. 61. TIPS• EARLY INSTITUTION OF PROSTIN• CY NB’s WITH MURMUR• ACY NB’s WITH ABNORMAL PULSES• EVEN WITHOUT ECHO• EARLY TRANSPORT• SUSPECT CHD WHEN: – PPHN TYPE PRESENTATION – SEPSIS
  62. 62. STARTING PROSTIN• Prior to starting, one needs to have Prostin available• This also remains a critical step outside the NCR• Since cost issues involved Pediatricians may not want to use it without a confirmation
  63. 63. STARTING PROSTIN• Ease of use of Prostin is directly proportional to: – Severity of Illness – Ease of availability• Confounding Factor: Echo should be done or not ?
  64. 64. DOSAGE• START WITH 0.05 mcg/Kg/Min• 500 mcg/ml• Put 1 ml in 25 ml• Infuse at 0.5ml/hr = 0.05mcg/Kg/Min• To allow 0.1 mcg/kg/min increase drip rate to 1ml/hr
  65. 65. SIDE EFFECTS• APNEA – DOSE RELATED – OVERCOME WITH AMINOPHYLLINE – NO NEED TO INTUBATE• Aminophylline: Bolus dose of 6 mg/kg before or during initiation of PGE1, and continued at 2 mg/kg dose every 8 hours for 72 hours.• PEDIATRICS Vol. 112 No. 1 July 2003, pp. e27-e29
  66. 66. • PROSTIN VR Rs 7-8000 (Pfizer)• ALPROSTADIL Rs 5000 (Samarth)• BIOGLANDIN Rs 4000 (United)
  67. 67. EARLY INFANCY ANDDETECTION OF CHD
  68. 68. CLASSIFICATION OF CHD• ACYANOTIC • CYANOTIC• Increased Flow • Decreased Flow – ATRIAL: ASD – TOF – VENTR: VSD – Pulm Atresia – ARTERIAL: • Increased Flow PDA – TAPVD – COMBINED: – TGA VSD+PDA – Truncus• No Shunts – Tricuspid Atresia – Pulm or Aortic Stenosis
  69. 69. STEPS IN CLINICAL DIAGNOSIS• CYANOTIC Vs ACYANOTIC• INCREASED FLOW Vs DECREASED FLOW
  70. 70. CLINICAL DIAGNOSIS• HISTORY: Increased flow or not• Pulse oximeter: Acyanotic vs Cyanotic• Chest Xray: increased Flow or not
  71. 71. HISTORY • Sweating while feeding • Shortness of breath • Failure to thrive • Recc infections (Lower) chestINCREASED PULMONARY BLOOD FLOW ACYANOTIC OR CYANOTIC
  72. 72. HISTORY• Cyanosis• Spells• Squatting• Syncope, Chest Pain
  73. 73. ACYANOTIC Vs CYANOTIC• Normal Saturations are >94%• Between 93 and 85% human eye cannot detect desaturation• Below 85% we can visually diagnose Cyanosis
  74. 74. ACYANOTIC Vs Cyanotic• ACYANOTIC • CYANOTIC• Pulse Oximeter • Sats less than 93%• Sats >94%
  75. 75. CHEST XRAY• LUNG FIELDS: – INCREASED : INCRD PULM BLOOD FLOW – OR OLIGEMIC: NORMAL OR DECRSD PBF

  92. 92. FEVER• The fever typically is high-spiking and remittent, with peak temperatures generally 39°C (102°F) and in many cases 40°C (104°F).
  93. 93. HANDS AND FEET• Erythema of the palms and soles or firm, sometimes painful induration of the hands or feet• Desquamation of the fingers and toes usually begins in the periungual region within 2 to 3 weeks after the onset of fever and may extend to include the palms and soles• Approximately 1 to 2 months after the onset of fever, deep transverse grooves across the nails (Beau’s lines)
  94. 94. SKIN RASH• Erythematous rash usually appears within 5 days of the onset of fever most common is a nonspecific, diffuse maculopapular eruption.• Urticarial exanthem, a scarlatiniform rash, an erythroderma, an erythema-multiforme- like rash, or,rarely, a fine micropustular eruption• Bullous and vesicular eruptions have not been described
  95. 95. EYES• Bilateral conjunctival injection bulbar conjunctivae (sparing the limbus, an avascular zone around the iris)• Exudate, conjunctival edema or corneal ulceration usually is painless• Mild acute iridocyclitis• Anterior uveitis
  96. 96. ORAL CAVITY• Erythema, dryness, fissuring, peeling, cracking, and bleeding of the lips• A “strawberry tongue” that is indistinguishable from that associated with streptococcal scarlet fever, with erythema and• Prominent fungiform papillae• Diffuse erythema of the oropharyngeal mucosae.
  97. 97. LYMPH NODES• Cervical lymphadenopathy is the least common of the principal clinical features• It is usually unilateral and confined to the anterior cervical triangle• Classic criteria include 1 lymph node that is 1.5 cm in diameter.
  98. 98. JOINT INVOLVEMENT• Arthritis or arthralgia can occur in the first week of the illness• Tends to involve multiple joints, including the small interphalangeal joints as well as large weightbearing joints• Arthritis or arthralgia developing after the 10th day of illness favors large weight- bearing joints, especially the knees and ankles.
  99. 99. RARE PRESENTATIONS• Transient unilateral peripheral facial nerve palsy occurs rarely• Transient high-frequency sensorineural hearing loss (20–35 dB) can occur during acute Kawasaki disease
  100. 100. DIAGNOSIS OF KD• Supplemental laboratory criteria include • albumin <3.0 g/dL, • anemia for age • elevation of alanine aminotransferase,• Platelets after 7 days >450 000/mm3• White blood cell count >15 000/mm3• Urine >10 white blood cells/high-power field.
  101. 101. ENZYME ELEVATION• Mild to moderate elevations in serum transaminases occur in 40% of patients and mild hyperbilirubinemia in 10%• Plasma GGT is elevated in 67% of patients• Hypoalbuminemia is common and is associated with more severe and more prolonged acute disease
  102. 102. URINE ANALYSIS• Urinalysis reveals intermittent mild to moderate sterile pyuria in 33% of patients, although• Suprapubic urine generally does not show pyuria, which suggests urethritis
  103. 103. LUMBAR PUNCTURE• Lumbar puncture, 50% demonstrate evidence of aseptic meningitis with a predominance of mononuclear cells, as well as normal glucose and protein levels.
  104. 104. DIAGNOSIS• The classic diagnosis of Kawasaki disease has been based on the presence of 5 days of fever and 4 of the 5 principal clinical features• All of the clinical features are not present at a single point in time, and watchful waiting is sometimes necessary before a diagnosis can be made

Pediatrics. 1998 Aug;102(2):e15• Diagnostic accuracy of pediatric echocardiograms performed in adult laboratories. Am J Cardiol. 1999 Mar 15;83(6):908-14.
  167. 167. Well Baby Check: VSD• Echocardiogram shows a VSD• This is obviously not an emergency:• Except: if an assoc lesion is not picked up• Especially if Coarctation is missed
  168. 168. Well Baby Check: VSD• From echo report determine if the VSD is –LARGE: Most likely to require surgery –MODERATE: Needs f/u –SMALL: Reassurance
  169. 169. LARGE VSD• Today the surgical mortality of VSD closure is 1-2%.• It is a curable lesion• No long term implications• Beyond 1 yr post-op only once a year f/u required• Normal life-span and quality of life• ONLY TIMING OF SURGERY AND MEDS IN MEAN TIME NEED BE DECIDED
  170. 170. LARGE VSD: MEDICAL• Mx NEED MAX A/LOAD REDUCTN – Tab. Envas(2.5mg) start w 1/4th OD->BD – Then increase to ½ later• PRELOAD REDUCTN HELPS – T. Frusemene (20mg) 1/8th in newborns – & 1/4th in infants ~ 5 Kg weight• DIGOXIN IN EARLY STAGE WHEN IN CHF – Elixir Dixin 0.3 ml BD for a 3 Kg child
  171. 171. VSD WHEN TO OPERATE ?• LARGE VSD’s: 3 MONTHS; By 6 MONTHS – IF WEIGHT GAIN NOT APPR – AND/OR IF PULM HTN DEVELOPING• MODERATE VSD’S INDIVIDUALIZED• SMALL VSDS – • AORTIC INSUFFICIENCY • INFECTIVE ENDOCARDITIS
  172. 172. Interventional PM VSD CLOSURE• AN EXPERIMENTAL METHOD• LONGTERM EFFECTS NOT KNOWN• HEART BLOCK: NEED OF PACEMAKER• AORTIC INSUFFICIENCY NOT KNOW• WOULD NOT RECOMMEND
  173. 173. VENTRICULAR SEPTAL DEFECTS
  174. 174. MUSCULAR VSD CLOSURE• AN ESTAB METHOD• PREFERRED METHOD• LONGTERM EFFECTS: NONE• FAR FROM CONDUCTION SYSYTEM• AORTIC INSUFFICIENCY UNKNOW
  175. 175. VSD: MX ISSUES• IMMUNIZATN: NO CONTRA-INDICATION• TRAVELLING: NO C/I (INCL AIR)• AVOID INFECTIONS (HOW EASY ?) – AVOID CROWDED PLACES – USE OF BRONCHODIL• PLOT HT & WT ALL VISITS• FEEDING ISSUES/ WEANING-VERY IMPORTANT
  176. 176. MX ISSUES• SPORTS: – ALL SPORTS ACTIVITIES CAN BE UNDERTAKEN – WEIGHT LIFTING IS NOT REC IN CHILDREN• PROFESSIONAL LIFE – SMALL VSD PTS CAN UNDERTAKE ALL PROFESSIONS EXCEPT: MILITARY, AEROSPACE AND OLYMPIAN• FINANCES – ONE TIME SURGERY MAY BE LESS EXPENSIVE THAN THE LIFETIME MX OF AN ASTHMA PT

  178. 178. NEONATAL PRESENTATION• THE BLUE BABY• THE PINK BABY IN DISTRESS• THE SHOCKY BABY
  179. 179. PINK BABY W/RESP DISTRESS• PREMATURE – THIS IS THE BABY WITH PDA-HAS BEEN DOING WELL NOW W INC O2 REQUIREMNTS; OR WITH APNEA; NEC; POOR PERFUSION ! – DIAGNOSIS IS BY ECHO ONLY !• START THERAPY AFTER ECHO ONLY*
  180. 180. PREMATURE-PDA• THERAPY – INDOMETHACIN: IV OR ORAL• ORAL OR RECTAL BRUFEN SYRUP – ADVANTAGES Vs DISADVANTAGES
  181. 181. PREMATURE-PDA• THERAPY – ONLY RECORDED DIFFERENCE IN THE PDA CLOSURE BETWEEN BRUFEN AND INDOMETHACIN IS THE RECURRENCE RATE – BENEFIT: RENAL
  182. 182. BRUFEN/INDOMT-COCHRANE ANALYSIS-2003 • BRUFEN AND INDOMETHACIN: equally potent in closing PDA; trials to evaluate long-term neuro issues needed • PROPHYLACTIC INDOMTH: no longterm benefit in survival or outcome; only short term decrease in IVH • PROLONGED Vs SHORT COURSE INDOMTH: dec rate of PDA re- opening; prolonged course-assoc w/dec IVH & renal imapirment
  183. 183. PDA BEYOND NEONATAL PERIOD
  184. 184. PDA-WHEN TO CLOSE• ANY PDA THAT CAN BE AUSCULTATED NEEDS TO BE CLOSED• ANY SYMPTOMAYTIC PDA NEEDS TO BE CLOSED• SILENT PDA’S MAY/MAYNOT BE CLOSED IN POST NEONATAL PERIOD
  185. 185. PDA-WHEN TO CLOSE• POST 3 KGS ANY PDA CAN BE CLOSED• VERY LARGE PDAS: BABY DOES NOT GAIN WEIGHT-SO NO POINT WAITING• SMALL PDAS MX MEDICXALLY TILL ABOUT 5-

  200. 200. BLUE BABY..CARDIAC• DUCTAL DEPENDING LESIONS:RT HEART – PULM ATRESIA – TOF SEVERE – PULMONARY STENOSIS, SEVERE• MIXING LESIONS – TRANSPOSITION• START PROSTIN IN ANY OF THESE
  201. 201. CYANOTIC CHD• FURTHER OPTIONS – SEPTOSTOMY: MIXING LESION – STENTING THE DUCT: DUCT DEPENDENT – BT SHUNT• MOST IMP OUTCOME FACTOR – ACCURATE ECHO – EARLY TRANSPORT – AVOID INFECTIONS
  202. 202. TGA:WHEN & WHAT SURGERY• ALL TGA’s DIAGNOSED IN NEWBORN PERIOD: ARTERIAL SWITCH OPERATION• IDEALLY IN SECOND WEEK• CAN BE PERFORMED UPTO 4 WEEKS
  203. 203. ARTERIAL SWITCH
  204. 204. OTHER LESIONS• TAPVD: OPERATE AT DIAGNOSIS; DON’T DELAY• TRUNCUS; OPERATE AT DIAGNOSIS: NO ADVANTAGE IN DELAYING
  205. 205. COARCTATION• TO BE TREATED WHEN DETECTED• BALLOON AS PRIMARY MANAGEMENT GOOD OPTION EVEN IN THE NEWBORN:• RECURRENCE 30%; IF NO ASSOC PROBLEMS• POST-6 MO BALLOON IS PREFERRED
