Partial aortic root replacement for aneurysm of the right sinus of Valsalva.

An aneurysm of the sinus of Valsalva is clinically rare, and its operative indications and procedures are controversial. We herein report the rare case of a 68-year-old woman with severe right ventricular outflow tract obstruction caused by an aneurysm of the right sinus of Valsalva. We performed partial aortic root reconstruction using a bovine pericardial patch, and aortic valve replacement. Although this case provides evidence that these are suitable surgical techniques for treatment of aneurysm of the sinus of Valsalva, total aortic root replacement should have been chosen based on the pathological finding of aortic medial and valve degeneration.
