Which of the following disorders would most likely cause the patient's findings?
Options:
A. Bicuspid aortic valve
B. Common pattern transposition of the great arteries
C. Patent ductus arteriosus
D. Tricuspid atresia

babbu5508 - 11-14-10 13:59 The correct answer is A. Isolated bicuspid aortic value is a very common congenital anomaly, which may be completely asymptomatic or may cause modest noncyanotic obstruction related to stenosis. It is associated with an immediate diastolic murmur, related to some degree of aortic insufficiency that is often recognized in early childhood. Surgical correction of even mild to moderate stenosis or insufficiency is now recommended to prevent long-term damage to the heart muscle.

Re: 4302 babbu5508 - 02-27-11 13:46 Most patients with bicuspid aortic valve whose valve becomes dysfunctional will need careful follow-up and potentially valve replacement at some point in life.
