2. General Data:  Name: Baby Boy G  Neonate

3. History of the Present Illness  Baby Boy Guadiz is born to 22-year old primigravid 2 nd year nursing student mother, married to a 23-year old unemployed partner. Initial pre-natal check up of the mother was at 6 month at a local health center. CBC and urinalysis results done revealed normal results.

4. History of the Present Illness  UTZ done showed Single Live Intrauterine pregnancy, cephalic, good cardiac and somatic activity, 24-25 weeks AOG, to rule out hypoplastic Right Ventricle. For further evaluation, the mother consulted at our institution and was advised fetal 2D echo.

5. History of the Present Illness  The fetal 2D echo revealed pertinent findings of hypoplastic Left Ventricle, hypoplastiv Mitral Valve, and a patent foramen ovale. At 26-27 weeks AOG, the mother had trichomoniasis for which she was given metronidazole tablet for 7 days. At 37-38 weeks, the mother developed UTI. Cefuroxime 500mg BID was given for 7 days that provided symptomatic relief.

6. History of the Present Illness  The mother denied any exposure to viral exanthems and radiation. No illicit drugs and abortifacients use. She is a non-smoker; however, was a previous alcoholic beverage drinker. Hep B screening was non-reactive and OGCT was normal. No history of hypertension, allergy, thyroid disease, diabetes, asthma, or blood dyscrasia.

7. History of the Present Illness  Family history is negative for diabetes mellitus, hypertension, and cardiovascular disease. The mother came in our institution for follow up but was 3cm dilatation, 70% effacement intact BOW, there was progression of labor alongside with spontaneous rupture of BOW. Clear, non-foul smelling amniotic fluid was observed. Repeat fetal 2D echo was not done due to lack of funds.

8. History of the Present Illness  Patient was born live, term, singleton, male, delivered via normal spontaneous delivery, BW 2.75 kg, BL 48 cm, AS 6 and 7, MT 38-39 weeks AOG, AGA.

10. Physical Examination on Admission:  (-) Palpable neck masses, intact clavicle, no crepitations  (-) Chest deformities, symmetrical chest expansion, (-) retractions, clear and equal breath sounds  Adynamic precordium, regular heart rate and rhythm, S1 and S2 normal, (-) murmurs  Globular abdomen, (+) umbilical stump with 2 arteries and 1 vein, (-) organomegaly, (-) palpable masses  Grossly male, bilaterally descended testes, good rugae, patent anus  Femoral pulses full and equal, (-) Barlow, (-) Ortolani  Straight spine, (-) sacral dimpling, (-) tuft of hair  (+) Moro, grasp, rooting, plantar, and sucking reflexes

12. Indicators that heart disease may exist  Cyanosis  Cardiomegaly (Radiologic or Pericardial bulge)  Pathologic heart murmur  Tachypnea or overt respiratory distress (dyspnea)  Sweating especially during feeding  Increased or decreased pulses  Failure to thrive

13. Classification of Congenital Heart Diseases A) Acyanotic B) Cyanotic

14. Major Considerations  Is there a shunt (L  R or R  L)  Is there obstruction to inflow or outflow  Abnormal heart valves  Abnormal connections of great vessels  Combination

15. Subgroups of Acyanotic Diseases  Shunt anomalies  Valvular defects  Obstructive lesions  Inflow anomalies  Primary myocardial diseases

16. Shunt Anomalies  L  R shunt  Increased pulmonary blood flow  Increased pulmonary vascular arterial markings on chest Xray  ASD, VSD, PDA

17. Obstructive Lesion  Discrepancy in amplitude of the peripheral pulses  Coarctation of the Aorta

18. Inflow Anomalies  Increased pulmonary venous markings on chest Xray  No murmur  Cor Triatriatum, Pulmonary vein stenosis

19. Valvular Defects  Stenosis or regurgitant  Characteristic murmur  AS, AR, PS, PR, MS, MR, TS, TR

20. Primary Myocardial Diseases  No murmur  Disparity between cardiac size and pulmonary vascular markings  Glycogen storage disease  Cardiomyopathy

21. Hemodynamic Consequences A) Volume (Diastolic) overload B) Pressure (Systolic) overload

22. ASD Hemodynamic Consequence Diastolic overload of RV

23. VSD  Hemodynamic Consequence  MODERATE SIZE  Volume overload of LV  LARGE SIZE  Volume overload of LV  Pressure overload of RV

24. Cyanotic Heart Disease  Cyanotic heart disease exist when one defect or association of defects allow the mixture of saturated and de-saturated blood to reach the systemic circulation

25. Do you suspect that patient is Cyanotic?  When in doubt A) Clubbing B) CBC C) Hyperoxia test

26. Hyperoxia Test  Hyperoxia test is considered positive for intracardiac shunting if PO 2 < 150 mmHg (torr) after 10 minutes of 100% fiO 2

27. PVA / IVS  Hemodynamic Consequence  Pressure overload of RV

28. PVA / VSD  Hemodynamic Consequence  Pressure overload of RV

29. PDA Dependent Pulmonary Circulation  Pulmonary valve atresia (PVA) with intact interventricular septum  Other lesions with accompanying PVA

30. Approach to diagnosis A) Chest XrayIncreased or decreased pulmonary vascular arterial markings B) EKGRVH, LVH, CVH C) Character of second heart sound S2 single, loud S2 single, normal Split S2

32. Causes of Cyanosis NoncardiacCardiac Pulmonary disorders (structural abnormalities of the lung, ventilation- perfusion mismatching, congenital or acquired airway obstruction, pneumothorax, hypoventilation) Abnormal forms of hemoglobin (methemoglobin) Poor peripheral perfusion (sepsis, hypoglycemia, dehydration, hypoadrenalism) primary or persistent pulmonary hypertension Increased pulmonary vascularity D-TGA TAPVR without obstruction PTA Single ventricle DORV w/o PS PPHN Decreased pulmonary vascularity TOF Ebstein’s anomaly PS PA TA with PS DORV with PS

33. Pulmonary Vascular Markings Decreased: Cyanotic TOFTricuspid Atresia Complex heart with PSPVA / IVS

34. Second Heart Sound (S2) Single LoudSingle NormalSplit S2 TGATOFTAPVR without obstruction Aortic / Mitral atresia Tricuspid atresia Truncus Arteriosus PVA

35. Cardiac Work-Up A) EKG B) Chest Xray C) 2D echocardiography (TTE, TEE, ICE, IVUS) D) Cardiac catheterization E) CT angiography, cardiac MRI
