Résumé
The study aimed to evaluate the early feasibility of endovascular replacement of ascending aorta, aortic root (including aortic valve, AV), and mitral valve (MV) in one procedure with two self-expandable prostheses. Aortic valved-fenestrated-bifurcated (AVFB) and MV endografts of 10 healthy pigs (60-65kg) were customized and delivered through transapical and transseptal approach, respectively. Both endografts were successfully deployed in nine pigs (90%). Eight survived over 24 h, and the acute success rate was 80%. There was no significant increase in the mean trans-aortic, trans-mitral, and trans-LVOT pressure gradients after the operation. No coronary artery or LVOT obstruction and other electrocardiographic abnormality occurred. The transvalvular and paravalvular leak rates were low for both valves. Endovascular replacement of ascending aorta, AV, and MV in one procedure might be feasible. Combined transcatheter replacement of aortic root and mitral valve in one procedure.
