Transcatheter ACURATE-TA aortic valve implantation in a patient with a previous mechanical mitral valve

Bagur R, Kiaii B, Teefy PJ, Diamantouros P, Harle C, Goela A, Chan I, Chu MW


Transcatheter aortic valve implantation (TAVI) in the presence of a mechanical mitral valve (MMV) prosthesis is still challenging because of the rigid mitral frame within the aortomitral curtain. Moreover, low-lying coronary ostia represent a hazardous problem of coronary obstruction, especially in narrow or porcelain aortic roots. The present case demonstrates the successful management of 2 challenging anatomical issues, the rigid cage of the MMV and the low-lying left main coronary ostium (LMCO), with the implantation of the ACURATE-TA bioprosthesis (Symetis SA, Ecublens, Switzerland). It also highlights the importance of having multiple TAVI devices in order to choose the ideal transcatheter aortic bioprosthesis to fit the unique anatomical presentation of the patient.
