Aneurysm of the Aortic Sinus Sinus of Valsalva

The aortic sinuses are located at the aortic root, directly superior to the aortic valve. They comprise the right coronary sinus and the left coronary sinus, which correspond to the relevant coronary arteries, and the posterior, acoronary sinus. In cases of an abnormal or even congenitally missing media of the vessel wall in the aortic root, aneurys-matic dilation of a sinus of Valsalva may occur. Typically, these congenital aneurysms involve the right coronary sinus (90%). However, they may also be acquired in response to arteriosclerosis, post-inflammatory changes or trauma. The clinical manifestation ranges from asymptomatic to medi-astinal hemorrhage and rupture into the chambers of the heart [5,6].
