Repair of intrapericardial rupture of left sinus of Valsalva aneurysm.

A 62-year-old man with no history of preexisting heart disease was seen in cardiogenic shock. Prompt cardiac catheterization and aortography revealed pericardial tamponade and aneurysms of the right and left sinuses of Valsalva. Immediate sternotomy relieved the tamponade, which was secondary to an aneurysm of the left sinus of Valsalva rupturing into the transverse pericardial sinus. Endoaneurysmorrhaphy was performed successfully.
