Valsalva Sinus Aneurysm

Also known as aortic sinus aneurysm, the Valsalva sinus aneurysm is a blood-filled balloon-like bulge in the wall of the sinus of Valsalva. According to resent research, this type of aneurysm originates from incomplete fusion of the distal bulbar septum which divides the aorta nad pulmonary artery and attaches to the anulus fibrosus of the aortic valve. This aneurysm is congenital in the majority of cases, accounting for 0.1%-3.5% of congenital heart disease. The incidence of Valsalva sinus aneurysm seems to be higher in Far East Asia.

Valsalva sinus aneurysm may be asymptomatic as long as it does not burst. Nevertheless, there have been a few reported cases of unruptured sinus of Valsalva aneurysms which have presented with conduction disturbances, myocardial ischemia, and symptomatic cardiac dysfunction. If it does rupture, it may lead to hemopericardium, hypovolemic shock and, and to death if not treaty urgently.
