  1. Neonate in Cardiac Distress Clinical Recognition SavitriShrivastava Director - Pediatric & Congenital Heart Diseases Fortis Escorts Heart Institute New Delhi, India

  2. Why Important ? - 1% Live Births - 2 % in Premature infant 30% need Urgent Attention Infant Mortality - 25 % due to Heart Defects Early recognition and prompt management can save most of them New Born in Cardiac Distress • Congenital Heart Disease

  3. Neonatal Heart Disease High index of suspicion Prompt recognition Early stabilization Timely referral New Born in Cardiac Distress “ Crucial for an optimal outcome”

  4. New Born in Cardiac Distress Fetal Diagnosis

  5. Is the Neonatal Distress due to Heart Disease? Bed side evaluation has limitations! • Some important clinical clues are useful • - History/Physical Examination • - X Ray Chest • - EKG • - Pulseoximeter/Hyperoxia test • Echocardiogram

  6. New Born in Cardiac Distress Neonate in Cardiac Distress Presentation Symptoms:- • Lethargy , Irritability • Difficulty in feeding • Fast respiration • Increased precordial activity • Bluish discoloration Sudden deterioration in symptoms (Duct dependant Lesions) Contd..

  7. New Born in Cardiac Distress Neonate in Cardiac Distress Physical Examination • Pallor , Mottled Skin, Cyanosis • Respiratory distress, Grunting • Weak /unequal pulses • Low/ unequal B.P.

  8. Cyanosis - Hyperoxia Test New Born in Cardiac Distress 100% O2~10 min.. < 70 < 150 150 to 200 >200 CHD very likely CHD likely  CHD unlikely PO2 (mmHg)

  9. New Born in Cardiac Distress Duct Dependent Mixing Severe Cyanosis with Cardiomegaly • Tachypnoea, Tachycardia • Hypatomegaly, Gallop • Insignificant murmur • X Ray Chest – CE / narrow pedicle / pulmonary plethora Most likely dTGA Intact septum, without PS

  10. New Born in Cardiac Distress Duct Dependent Pulm. Circulation Severe Cyanosis PBF • No CHF, No Cardiomegaly • Single Second Sound • Ejection murmur + • Continuous murmur + • No S3, No mdr • Pulm. Atresia / Severe RVOTO with TOF physiology • Pulmonary atresia Intact septum

  11. New Born in Cardiac Distress CHF, Shock Duct Dependent Syst. Circulation • Weak femoral pulses • B.P. - Right Upper Limb - Lower Limb • Saturation - Right Upper Limb - Normal - Lower Limb - Low • Severe Coarctation • Arch Interruption • HLHS - Unequal

  12. New Born in Cardiac Distress Respiratory Distress , Cyanosis, PAH • CHF • Cardiomegaly + • No murmur or TR murmur • P2 loud, S3 • Chest X ray TAPVC with Obstruction Contd….

  13. Respiratory Distress , Cyanosis, PAH Marked  in PO2 • PA Chest New Born in Cardiac Distress Hyperoxia Test No Significant  in PO2 Pulm. Lesion PPHN

  14. New Born in Cardiac Distress CHF, Severe Cyanosis, No PAH • CE, PBF, CHF • Multiple Heart Sounds • TR murmur Ebstein’s Anomaly Contd..

  15. New Born in Cardiac Distress CHF, Severe Cyanosis, No PAH • Ejection Syst. Murmur • TR Murmur • S3, S4 Critical PS + TR

  16. New Born in Cardiac Distress CHF, Mild Cyanosis • Cardiomegaly • Flow murmurs • Admixture Lesions • TGA Physiology without PS • TAPVC without Obstruction • AR murmur • - Patent Trunkus Arteriosus

  17. New Born in Cardiac Distress Respiratory Distress, Mild Cyanosis • Ejection systolic murmur • PR murmur • X Ray Chest Absent Pulmonary Valve Syndrome

  18. New Born in Cardiac Distress Acyanotic, CHF, Shock • Lethary/Irritability • CHF • MR murmur ALCAPA Contd..

  19. Acyanotic, CHF,Shock Weak Pulses Cardiomegaly Ejection Syst. Murmur , S3, S4 X Ray Chest – Cardiomegaly EKG New Born in Cardiac Distress Critical AS

  20. New Born in Cardiac Distress Acyanotic with CHF • Cardiomegaly • Flow murmurs - Multiple sites of shunts - Associated * LVOT Obstruction * Regurgitant lesion

  21. New Born in Cardiac Distress Acyanotic CHF • Primary myocardial disease • Secondary myocardial dysfunction • Hypocalcaemia/Hypoglycemia/Diabetes • Perinatal asphyxia, Sepsis • Adrenal insufficiency • Metabolic and Genetic Disorders • Glycogen Storage Disease( Pompe’s disease) Contd..

  22. New Born in Cardiac Distress Arrhythmia resulting in Myocardial Dysf. & CHF • Tachyrrhythmia - SVT • Bradyarrhythmia - CHB

  23. New Born in Cardiac Distress Acyanotic CHF with High Output State Bounding Pulses • Term Baby • - No significant cardiac murmur • - Continuous murmur over head • A-V Fistula – Cerebral • Premature Baby - Good volume pulses - Pulsation 2LIC space, arch - Continuous murmur + - Ejection murmur below left clavicle • PDA in premature babies • Severe Anemia

  24. New Born in Cardiac Distress Neonate in Cardiac Distress Cyanotic Mild Cyanosis Severe Cyanosis PA Chest * PBF – PS *  PBF – TGA * Severe PVH Obst. TAPVC Shock, Weak Fenorals * Coarct. * AA Interruption * HLHS Resp. Distress PA Chest - Hilar Pas ++ * APV CHF PA Chest PBF * Admixture Lesions

  25. New Born in Cardiac Distress Neonate in Cardiac Distress Acyanotic, CE, CHF PA Chest – CE, NPBF • High Output State • Cerebral AVM • PDA Premature NB • Severe Anemia • ALCAPA • Critical AS • Critical Coarct. • Arrhythmia • Myocardial diseases • Primary • Secondary

  26. New Born in Cardiac Distress Take Home Message • High Index of Suspicion • Systematic approach without panic • Careful evaluation of Bedside Clues, Chest X ray and EKG gives enough information to plan emergency management and prompt referral, to tertiary care centre resulting in excellent results.
