The role of multimodality imaging in the selection of patients for aortic valve repair.

Aortic valve sparing surgery for aortic regurgitation and/or aortopathy serves as an alternative to aortic valve and root replacement. One of the advantages of aortic valve sparing surgery over conventional replacement is that there is no need for life-long anticoagulation, which is particularly attractive in young patients who may receive a mechanical prosthesis otherwise. However, successful aortic valve repair requires high expertise. At present, reparability is determined intraoperatively by direct surgical inspection. Preoperative imaging techniques might improve the patient selection for aortic valve repair. The mechanism of aortic regurgitation, aortic valve morphology and calcification and aortic root dimensions are all of importance when aortic valve repair is considered. The present review focuses on the role of imaging techniques in determining aortic valve reparability.
