Alternative methods to overcome the challenging anatomy of the coronary sinus during percutaneous mitral annuloplasty procedure

Özet

Dilated cardiomyopathy (DCM) is usually associated with variable degrees of functional mitral regurgitation (FMR), which contributes to higher morbidity and mortality. At present, the optimal management strategy for FMR is not clearly defined in the guidelines. A variety of percutaneous valve interventions to improve patients’ quality of life and decrease morbidity and mortality have been developed recently. The CARILLON Mitral Contour System is a fully transvenous approach using the anatomical proximity of the coronary sinus (CS) to the mitral annulus. In this technique, a device consisting of distal and proximal anchors linked by a flexible nitinol clip is introduced via the CS to encircle around two thirds of the mitral annulus, thereby, creating a tension constricting the mitral annulus (1). When properly deployed within the CS, it can lead to marked symptomatic and functional improvement with a low rate of major adverse events (1-3).
