The disappearance of a ventricular septal defect (VSD) murmur in a patient known to have a large left-to-right shunt is most likely due to



1) development of aortic stenosis.

2) closure of ventricular septal defect (VSD).

3) increase in the left-to-right shunt.

4) development of pulmonary stenosis.

5) development of significant pulmonary arterial hypertension.

5- dev of significant pulmonary HTN ?

Agree with 5

yes, 5. equalization of pressures on the right and left side. will lead to Eisenmenger syndrome ie rt to left shunt if left untreated



  #7

with complete eisenmenger and rt-lt shunt will any murmur be heard?


  #8

eisenmanger 5.



  #9

with equalization of pressure there will be no murmer. when right sided pressures increase more than left sided, there would be a rt to right shunt and a murmur would be heard again.
