Since aortic root reoperations are challenging procedures, alternative lower-risk procedures should be considered in certain cases. Herein are presented two different approaches to high-risk root reoperations. The first patient, a 59-year-old male who had undergone root replacement 11 years previously with an Edwards Prima stentless valve, presented with severe aortic regurgitation and a heavily calcified aortic root. An open implantation of an Edwards Sapien valve was performed via an aortotomy distal to the calcified aortic root. The second patient, a 60-year-old female, underwent transapical implantation of an Edwards Sapien transcatheter valve for stenosis of the aortic valve in an aortic homograft implanted 11 years previously. The long-term durability of these implants has yet to be evaluated.
