Surgical repair of ruptured sinus of Valsalva aneurysm can be challenging, although it has been reported that mortality and morbidity is low. Distortion of sinus of Valsalva geometry can cause aortic valve regurgitation immediately or progressively after surgery. Maintenance of the appropriate geometry of sinus of Valsalva after resection of the aneurysm is critical in preserving the native aortic valve and its competency. Successful reconstruction with various patch materials such as Dacron patches (DuPont, Wilmington, DE) or pericardial patches has been reported. Nevertheless, the size and shape of patches used had to be created impromptu by surgeons without reliable methodology of reproducing the precise shape of the naturally occurring sinus of Valsalva. Herein, we report a successful repair of sinus of Valsalva aneurysm by utilizing a porcine sinus of Valsalva from a commercially available Freestyle valve (Medtronic Inc, Minneapolis, MN). We believe that this is a previously unreported technique.
