Congenital aneurysm of the pulmonary sinus of Valsalva

ANEURYSM OF PULMONARY SINUS OF VALSALVA: SUCCESFUL MANAGEMENT OF A CASE

Pulmonary Sinus of Valsalva (PSOV) aneurysm is an extremely rare entity, reported only twice in the literature. It can remain asymptomatic or can present with symptoms when associated with pulmonary artery aneurysms. We present a case of PSOV aneurysm causing severe right ventricular outflow tract (RVOT) obstruction. This report aims to alert the physicians of such an entity when evaluating the causes of sub-valvar RVOT obstruction.

Sinus of Valsalva aneurysms

Sinus of Valsalva aneurysms are rare cardiac anomalies which may be acquired or congenital. The congenital aneurysm is more common than the acquired form, with an incidence ranging from 0.1 to 3.5% of all congenital heart defects. Acquired aneurysms may result from trauma, endocarditis, syphilis, Marfan's syndrome, and senile-type dilatation in which the three sinuses dilate as a result of the normal aging process. This review focuses on both congenital and acquired aneurysms with particular attention to the noninvasive diagnosis of this anomaly.
