Rupture of aortic sinus

Rupture of aortic sinus

If there is any aneurysm of the aortic sinus or sinus of valsalva, then it may rupture due to some causes. These are:1. infective endocarditis involving the aortic wall.2. syphilis etc.

The manifestations appear depending on the site where the sinus has ruptured. For eg.if the sinus ruptures in a low pressure area like rt. atrium or rt. ventricle then a continuous type of murmur is heard.The murmur is located in the left parasternal region mainly confined to the lower sternum.It is also accompanied by a superficial thrill.
