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.
