C. Heart Conduction System
D. Response to preload
C
The following are true EXCEPT:
A. The ductus venosus closes after clamping of the umbilical cord and subsequent collapse of the umbilical vein
B. The ductus arteriosus closes due to lung expansion and increased oxygen tension.
C. The foramen ovale closes when the pressure in the left atrium exceeds that of the right atrium
D. The direction of the shunt through the foramen ovale is always maintained from right to left until it closes
D
The shunt shifts from right-to-left to left-to-right due to increased systemic resistance brought about by the loss of the placental circuit and decreased pulmonary resistance because of expanded lung vasculature with breathing. This reversal is the reason for the closure of the foramen ovale. Therefore, the shunt is not exclusively maintained in a right-to-left direction.

B
A, C, and D may have systolic ejection murmurs while B (VSD) will have a pansystolic/holosystolic murmur along lower left sternal border.
A 12-year old child with rheumatic heart disease consulted in the out-patient department. In the physical exam, a loud diastolic blowing at the apex was heard. The murmur is due to: A. Mitral regurgitation B. Aortic regurgitation C. Pulmonic regurgitation D. Tricuspid regurgitation
B
Regurgitation of blood from aorta back towards the left ventricle will be heard in the apex area (despite the apex being the “mitral” area). In contrast with a mitral regurgitation which will be heard more in the upward border
What auscultatory finding will be found in ASD? A. Wide split S1 B. Diastolic rumble at apex C. Systolic ejection murmur at base D. Midsystolic click at base
C
The systolic ejection murmur is attributable to relatively increased blood flow through pulmonic valve into pulmonary artery because of the left-to-right-shunt. It is heard at the base because that’s where the pulmonary auscultatory area is.
