Transcatheter aortic valve implantation in patients with pre-existing mechanical mitral valve prostheses
Transcatheter aortic valve implantation (TAVI) has become standard therapy for aortic stenosis patients with intermediate or high operative risk. Treatment of patients with pre-existing mechanical mitral valve replacement (MVR) is challenging due to possible interference between the TAVI prosthesis and MVR. We present our single-center experience with this special patient cohort.
TAVI in patients with mechanical MVR is challenging and requires careful preparation and choice of TAVI device. Repositionable and retrievable devices seem to be a safer option.
