Right Valsalva Sinus Aneurysm Protruding Into the Right Ventricle: A Case Report

A separation between the aortic media and annulus fibrosus causes a rare cardiac abnormality called sinus of valsalva aneurysm (sva) that may be congenital or acquired. it is more prevalent in the right coronary sinus (65%-85%) but it has been seen rarely in non-coronary (10%-30%) or left coronary sinus (<5%). the most common complication is rupture of the aneurysm. we present an 80-year-old male with expanding right valsalva sinus aneurysm and protruding into right ventricle. the conventional treatment is surgical repair under cardio-pulmonary bypass or percutaneous catheter closure. the aneurysm was successfully excised surgically under direct guidance of trans-esophageal echocardiography (tee).
