What is an aortic sinus aneurysm?

Aortic sinus aneurysm rupture may be caused by congenital dysplasia, pathogenic microorganism infection and other reasons.

1. Congenital dysplasia

patients in the embryonic development process, the occurrence of incomplete development of the base of the aortic sinus, resulting in sinus wall elastic fibers and muscle tissue too weak, may cause abnormal continuity between the aortic wall and aortic valve annulus, forming relatively weak tissue, high pressure blood flow continued to impact this site can form aortic sinus aneurysm, in the long run, can cause aortic sinus aneurysm rupture.

2. Pathogenic microorganism infection

patients infected with bacteria, fungi and other pathogenic microorganisms, may continue to invade the aortic sinus wall, resulting in aortic sinus wall damage, leading to aortic sinus aneurysm rupture.
