Rare type of congenital aneurysm of the right sinus of Valsalva protruding superiorly into the pericardial space.
We report a rare type of aneurysm of the sinus of Valsalva. The orifice of the aneurysm was in the right sinus of Valsalva and protruded superiorly, which is a direction not typical of right sinus of Valsalva aneurysms. Intraoperatively, it became clear that the aneurysm was located in the right sinus of Valsalva with extracardiac protrusion. Inspection through the aortotomy revealed that the orifice of the aneurysm opened between the orifice of the right coronary artery and the commissure between the right and left coronary cusps. The aneurysm was obliterated with a pledgeted suture from outside the orifice of the aneurysm. Early prophylactic surgical treatment of the aneurysm makes the operation simple and prevents subsequent development of complications, such as compression of the coronary artery, thrombosis, and/or spontaneous rupture.
