Dual exposure and repair technique for ruptured aneurysms of aortic sinus of Valsalva.

ABSTRACT

Thirteen patients with ruptured sinus of Valsalva aneurysm have been operated over a 3-1/2 year period. Right coronary sinus was predominantly involved and right ventricle was the most common site of rupture. Early surgery was performed in all cases. Both aorta and chamber of entry were explored for effective repair. Main repair was always done in the chamber of rupture either with a patch or interrupted pledgeted sutures followed by assessment at either end. Subannular ventricular septal defects in three cases were closed with a common patch with additional fixation in the middle at the aortic annulus to prevent aortic leak into the left ventricle. Three patients needed aortic valve replacement for gross aortic incompetence. Postoperative echocardiographic study revealed uniformly excellent results with good aortic valve or prosthetic function. One patient developed fatal pulmonary embolism two weeks following surgery. All other surviving patients are doing well and are in NYHA class I. We recommend dual exposure and repair technique for the repair of ruptured sinus of Valsalva aneurysms for optimal results.
