With adequate valve leaflet tissue and using current reconstructive techniques, patients should enjoy a well-functioning and durable aortic valve repair.

In their report “Valve repair for aortic regurgitation of a bicuspid aortic valve with root dilatation late after an arterial switch operation,” Nakaji and colleagues1 from Nagasaki University Hospital describe their technique for David root replacement and bicuspid valve repair. Their technique uses some novel maneuvers as well as more traditional steps which result in a very competent and nonobstructive valve. They provide very beautiful imaging, perform a precise valve analysis, and include a high-resolution, nicely edited video that shows the critical steps of the procedure.
This report provides support for many valuable tenets in aortic valve reconstructive surgery, especially for our younger patients. The precise and very detailed analysis of the valve using echocardiography and 3D computed tomography reconstruction allows advanced planning in a very thoughtful and comprehensive manner. Imaging has come a long way as shown by a recent article by Izawa and colleagues.2 The modern concepts of aortic valve reconstruction have undergone continuous improvement over the years. Although there are multiple subtle technical differences among the different publications in the literature, there are fundamental concepts, which when adhered to, allow for a more standardized approach and a more durable outcome than ever before.3, 4, 5, 6 In general, if there is adequate surface area and quality of valve leaflet tissue, and one uses precise preoperative imaging and intraoperative assessment and current reconstructive techniques, a competent/nonobstructive valve with very reasonable durability can be obtained. From a patient's perspective, the opportunity to retain one's own tissue, whose biologic behavior far exceeds that of any other biologic substitute at this time, will be much preferred if durability can be achieved. It is imperative that surgeons embrace this new reconstructive technique, else the only option for patients (and surgeons), will be a transcatheter valve with subsequent valve-in-valve repetitive procedures, patient valve mismatch, and ultimately, very challenging reoperations.
