Transapical aortic valve implantation: results of a Brazilian prosthesis.

OBJECTIVE The aortic valve replacement is a routine procedure with acceptable risk, but in some cases, such a risk can justify contraindication. The minimally invasive transcatheter aortic valve implantation has been viable, with lower morbidity and mortality. The aim of this study was to develop a national catheter-mounted aortic bioprosthesis for the aortic position implant. METHODS After a...

Patient-prosthesis mismatch after transapical aortic valve implantation.

OBJECTIVES Transcatheter aortic valve implantation (TAVI) has become an important therapeutic option for high-risk patients with severe aortic valve stenosis. Patient-prosthesis mismatch (P-PM) is an important determinant of morbidity and mortality after open aortic valve replacement. The objective of our study was to evaluate P-PM incidence and its impact on survival in a large cohort of patie...

Transapical Aortic Valve Implantation

Results Balloon redilation of the transcatheter valve was performed in 18 patients (5%), and additional second valves were implanted in 13 (4%). At the end of the procedure, 186 patients (52%) had no paravalvular or transvalvular regurgitation. In the remaining 172 patients, paravalvular leakage was observed in 113 (32%), transvalvular leakage in 47 (13%), and both in 12 (3%). Leakage was trace...

Transapical transcatheter aortic valve implantation in the presence of a mitral prosthesis.

OBJECTIVES We review our experience with transapical transcatheter aortic valve implantation (AVI) in patients with functioning mitral prostheses, and describe the technical considerations. BACKGROUND Transcatheter AVI for aortic stenosis in patients with mitral prostheses is technically challenging. METHODS Ten patients (7 mechanical and 3 bioprosthetic mitral valves) received the Edwards ...
