3. 🕓logy of Fallot
 M/C Congenital CYANOTIC heart ds
 Four Components
1. Large Unrestricted VSD
2. Over-riding🚵🚵🚵 of Aorta
3. Pulmonary infundibular stenosis
4. RV Hypertrophy
 🫀 cyanotic?
 Pulmonary stenosis… ⬇️ pul bld supply Cyanosis  hypoxia (c/f clubbing)

5. 📹

6. Clinical features
 Cyanosis
 Clubbing
 Polycythemia ( d/t compensation)
 Cyanotic spells
 AUSCULTATORY FINDINGS
 EJECTION SYSTOLIC MURMUR d/t Pul Stenosis
 Why not d/t VSD?
 As single VSD, Both ventricular P – same thus acts as a single ventricular chamber
 SINGLE S2 ❤️ sound
 Why single?

7.  Q) Which is not itself a complication or clinical f. of TOF
A) THROMBOSIS esp Stroke
B) INFECTIONS
C) HEART FAILURE
D) ACIDOSIS
Ans:
C) HEART FAILURE but can occur with other complic involved like myocarditis, I/E, Anemia
