BACKGROUND: In inoperable or high-surgical-risk patients, transcatheter aortic valve replacement (TAVR) and repair of the mitral valve using the MitraClip have emerged as novel treatment strategies. We sought to assess the feasibility and effectiveness of bivalvular transcatheter therapy in patients with coexisting aortic stenosis and mitral regurgitation. METHODS: Out of 285 patients treated with TAVR and 226 patients who underwent MitraClip therapy at our institution, 11 patients (78 ± 6years, 9 men [82%]) received both therapies. TAVR preceded MitraClip therapy in 10 patients, with 3 patients undergoing both interventions in a single session. RESULTS: TAVR via transapical (n = 6) or transfemoral (n = 5) access utilized the Sapien/Sapien XT and CoreValve prostheses in 7 and 4 patients, respectively. All TAVR procedures were successful, with significant increases in effective aortic orifice area and decreases in mean transvalvular pressure gradient. MitraClip therapy succeeded in reducing MR severity to <2+ in 10 patients. Periprocedurally, 1 patient sustained a stroke. At a median of 208 days, 2 patients were in NYHA functional class II, with only 1 patient improved from before TAVR, and 6 patients were in class III (improvement in 1). Four patients had died at a median of 60 days after MitraClip therapy. CONCLUSION: Bivalvular transcatheter treatment of patients with coexisting aortic stenosis and MR is technically feasible, even in a single session. Given the low prevalence of midterm functional improvement, factors predictive of clinical benefit from catheter-based double-valve intervention remain to be determined.
