Modified repair for huge unruptured aneurysm of the right sinus of valsalva.

Unruptured aneurysm of the sinus of Valsalva is a rare abnormality. In the present case, the huge aneurysm of the sinus of Valsalva was only involved in the right coronary sinus with the ostium far from its normal place. We designed a modified repair technique, with a scalloped Intergard woven vascular patch combined with aortic flap, to reconstruct the sinus of Valsalva and avoid the reimplantation of right coronary artery.
