| Abstract: | Background: There are scarce data available on transcatheter mitral valve replacement (TMVR), and these have been limited to procedural results, with no follow-up status reported.; Objectives: The goal of this study was to evaluate the feasibility, procedural results, and 6-month follow-up outcomes after TMVR with a mitral transcatheter heart valve (Fortis, Edwards Lifesciences, Irvine, California).; Methods: We report a series of 3 patients (mean age 71 ± 9 years, 2 men) who had TMVR under a compassionate clinical use program. All patients treated had functional mitral regurgitation (MR) secondary to ischemic cardiomyopathy (prior bypass surgery in all cases; left ventricular ejection fraction between 25% and 30%) and were considered to be at very high surgical risk (mean Society of Thoracic Surgeons score: 9.3).; Results: The procedure was performed through the transapical approach, and the valve was successfully implanted in all cases, with no major complications. At hospital discharge, echocardiographic evaluation revealed trace residual MR in 2 patients and no MR in 1 patient. The mean transvalvular mitral gradient was ≤4 mm Hg in all patients. At the 3-month follow-up, the valve function remained unchanged, and transesophageal echocardiography and computed tomography showed no structural failures. All patients had improvements in functional status, in exercise capacity as evaluated by 6-min walk test, and in quality of life. At 6-month follow-up, all patients remain alive, without hospital readmission for heart failure and with New York Heart Association functional class ≤II.; Conclusions: TMVR with this valve is feasible and is associated with good outcomes. Optimal valve functional results were obtained acutely and were sustained at 6-month follow-up in all patients. Further studies with a larger number of patients and longer follow-up are warranted.; (Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.) |
