A case of dilated cardiomyopathy and severe mitral regurgitation treated using a combined percutaneous approach of MitraClip followed by CARILLON® mitral contour system.

Functional mitral regurgitation (FMR) is common in severe heart failure. Medical therapy is the standard of care since the role of surgery is less established. Various trans-catheter percutaneous techniques may avoid the risks of surgery; such as edge-to-edge repair using MitraClip system (Abbott Vascular, Illinois, USA) and CARILLON® Mitral Contour System® (Model XE2; Cardiac Dimensions., Kirkland, WA, USA). We present the case of a 41-year-old man with severe dilated cardiomyopathy, NYHA IIIb, and grade 3 MR. Due to high surgical risk (logistic EuroScore 35.1) he initially underwent single MitraClip insertion with significant echocardiographic and clinical improvement (MR reduced from 3+ to 1+, NYHA classes III to II). Fifteen months later, he developed heart failure symptoms due to recurrence of severe MR and was retreated with percutaneous CARILLON® Mitral Contour System® with resolution of MR and doing well at nine-month follow-up. A combined approach of MitraClip followed by percutaneous mitral annuloplasty demonstrated clinically meaningful reduction of MR and resulted in significant symptomatic improvement for up to 6months. Follow-up for longer period is warranted to ensure sustained favorable outcome.
