N2 - OBJECTIVES: To compare the surgical and percutaneous edge-to-edge (EE) repair in patients with severe left ventricular (LV) dysfunction and secondary mitral regurgitation (MR). METHODS: We reviewed the prospectively collected data of the first 120 consecutive patients (age: 65 ± 9.8 years, EF: 28 ± 8.2%) treated with surgical (65 patients) or percutaneous (55 patients) EE repair for severe secondary MR in our institution. Age (P = 0.005) and logistic European System for Cardiac Operative Risk Evaluation (P <0.0001) were significantly higher in the MitraClip group. LVEF (P = 0.37), enddiastolic (P = 0.83) and end-systolic (P = 0.68) volumes and systolic pulmonary artery pressure (SPAP) (P = 0.58) were similar. The follow-up was 100% complete [median: 4 years; interquartile range (IQR): 2.2-7.2]. RESULTS: The length of hospital stay was 10 days (IQR: 8-13) for surgery and 5 days (IQR: 3.9-7.8) forMitraClip (P <0.0001). Hospitalmortality (3 vs 0%, P = 0.49) and freedom from cardiac death at 4 years (80.8 ± 4.9% vs 79.1 ± 5.9%, P = 0.9) were not significantly different in the surgical and MitraClip group, respectively. Residual MR = 2+ at hospital discharge was 7.6% for surgery and 29% for MitraClip (P = 0.002). At 4 years, freedom fromMR = 2+ (74.9 ± 5.6% vs 51.4 ± 7.4%, P = 0.01) and freedom from MR= 3+ (92.8 ± 3.4%vs 68.1 ± 7%, P = 0.002) were both significantly higher in the surgical group. Multivariate analysis identified the use of MitraClip as an independent predictor of recurrence of MR = 2+ [Hazard ratio (HR): 2.1, 95% confidence interval (CI): 1.1-3.9, P = 0.02] as well as of MR= 3 (HR: 6.1, 95% CI: 1.5-24.3, P = 0.01). In the surgical group, no predictors of cardiac mortality were identified. In the MitraClip group, left ventricular end-diastolic diameter (HR: 1.1, 95% CI: 1-1.2, P = 0.005) and SPAP (HR: 1, 95% CI: 1-1.1, P = 0.005) were independent predictors of cardiac death at the follow-up. CONCLUSIONS: MitraClip therapy is a safe therapeutic option in selected high-risk patients with secondary MR and relevant comorbidities. The surgical EE provides higher efficacy both postoperatively and at the mid-term follow-up.
