Comparative StudyLong-term survival, valve durability, and reoperation for 4 aortic root procedures combined with ascending aorta replacement.
To evaluate long-term results of aortic root procedures combined with ascending aorta replacement for aneurysms, using 4 surgical strategies. ⋯ These 4 aortic root procedures, combined with ascending aorta replacement, provide excellent survival and good durability. Valve-preserving and allograft procedures have the lowest gradients and best ventricular remodeling, but they have more late regurgitation, and likely, less risk of valve-related complications, such as bleeding, hemorrhage, and endocarditis. Despite the early risk of reoperation, we recommend valve-preserving procedures for young patients when possible. Composite bioprostheses are preferable for the elderly.

Prolonged continuous-flow left ventricular assist device support and posttransplantation outcomes: A new challenge.
To assess outcomes after cardiac transplantation in patients receiving long-term continuous-flow left ventricular assist device (CF-LVAD) support. ⋯ A bridge-to-transplant (BTT) strategy with a CF-LVAD has become standard care for patients with advanced heart failure. Duration of CF-LVAD support is associated with increased midterm mortality, warranting early transplantation in the modern BTT era.

North American single-center experience with a sutureless aortic bioprosthesis.
Surgical sutureless aortic valves have the potential for shorter procedural times and could benefit patients with increased risk. The Enable (Medtronic Inc, Minneapolis, Minn) valve is a bioprosthesis housed in a Nitinol cage allowing folding and deployment once implanted. We aimed to evaluate the early clinical and echocardiographic results with the Enable valve. ⋯ The Enable bioprosthesis is an acceptable alternative to conventional aortic valve replacement in higher-risk patients. The early hemodynamic performance seems favorable.
