A sinus of Valsalva aneurysm is a comparatively rare disease, and it has almost no symptoms unless this is rupture, whereas aortic insufficiency, myocardial ischemia and heart failure might be associated with un-ruptured aneurysm of the sinus of Valsalva. We encountered 2 elderly patients（71 years old and 83 years old）with huge un-ruptured aneurysm of the sinus of Valsalva which causes right ventricular outflow tract obstruction. The orifice of the aneurysm of the sinus of Valsalva was closed using ePTFE patches in the both cases. Plication of aneurysm was attempted in both cases, but it failed in case 1 due to undetermined border of the aneurysm on the right side of the heart. Case 2 was required concomitant aortic valve replacement with a bioprosthesis due to associated aortic regurgitation. The repair of un-ruptured aneurysm of the sinus of Valsalva associated with right ventricular outflow tract obstruction can be performed safely and effectively even in elderly patients.
