Transcatheter indirect mitral annuloplasty induces annular and left atrial remodelling in secondary mitral regurgitation.

ABSTRACT:

Aims

Mitral annuloplasty using the Carillon Mitral Contour System (CMCS) reduces secondary mitral regurgitation (SMR) and leads to reverse left ventricular remodelling. The aim of this study was to evaluate the effect of the CMCS on the mitral valve annulus (MA) and left atrial volume (LAV).

Methods and results

We retrospectively evaluated the data of all patients treated with the CMCS at our centre. Using transthoracic echocardiography, MA diameters were assessed by measuring the anterolateral to posteromedial extend (ALPM) and the anterior to posterior (AP) dimensions, respectively. Also, LAV and left ventricular end-diastolic volume (LVEDV) were assessed. Patients were examined at three time points: baseline, at 20-60 days (30dFUP), and at 9-15 months (1yFUP), using paire
