ObjectiveTo evaluate the outcomes of robotic mitral valve repair (MVr) by primary indication per American Heart Association guidelines for surgery: class I vs class IIa.Patients and MethodsFrom January 1, 2008, through September 30, 2016, 603 patients underwent robotic MVr for severe primary mitral regurgitation. Medical records of 576 consenting patients were retrospectively reviewed to determine the primary indication for surgery. Patients were stratified into class I or class IIa, and preoperative, intraoperative, and postoperative variables were compared.ResultsOf 516 patients, 428 (83%) had class I indication and 88 (17%) had class IIa indication for surgery. Preoperatively, no significant differences were observed between both cohorts. Importantly, a significantly higher number of patients with class I indication underwent MVr for bileaflet prolapse (172 of 428 [40%] vs 21 of 88 [25%]; P=.03). Early MVr outcomes indicated recurrent mitral regurgitation (moderate or greater) in only 12 of 576 (2%), and no significant differences were observed between classes (P=.23). Apart from parameters for ventricular size, all other intraoperative and postoperative variables were comparable between both cohorts.ConclusionComparable outcomes were indicated across all classes of indications for MVr surgery. These results continue to support the use of this surgical technique, even in less sick patients. Early referral along with more extensive robotic MVr experience will likely result in further improvements in long-term outcomes. 相似文献

ObjectiveTo evaluate the prevalence and natural history of mitral annulus calcification (MAC) and associated mitral valve dysfunction (MVD) in patients undergoing clinically indicated echocardiography.MethodsA retrospective review was conducted of all adults who underwent echocardiography in 2015. Mitral valve dysfunction was defined as mitral regurgitation or mitral stenosis (MS) of moderate or greater severity. All-cause mortality during 3.0 (0.4 to 4.2) years of follow-up was compared between groups stratified according to the presence of MAC or MVD.ResultsOf 24,414 evaluated patients, 5502 (23%) had MAC. Patients with MAC were older (75±10 years vs 60±16 years; P<.001) and more frequently had MVD (MS: 6.6% vs 0.5% [P<.001]; mitral regurgitation without MS: 9.5% vs 6.1% [P<.001]). Associated with MS in patients with MAC were aortic valve dysfunction, female sex, chest irradiation, renal dysfunction, and coronary artery disease. Kaplan-Meier 1-year survival was 76% in MAC+/MVD+, 87% in MAC+/MVD?, 86% in MAC?/MVD+, and 92% in MAC?/MVD?. Adjusted for age, diabetes, renal dysfunction, cancer, chest irradiation, ejection fraction below 50%, aortic stenosis, tricuspid regurgitation, and pulmonary hypertension, MAC was associated with higher mortality during follow-up (adjusted hazard ratio, 1.40; 95% CI, 1.31 to 1.49; P<.001); MVD was associated with even higher mortality in patients with MAC (adjusted hazard ratio, 1.79; 95% CI, 1.58 to 2.01; P<.001). There was no significant interaction between MAC and MVD for mortality (P=.10).ConclusionIn a large cohort of adults undergoing echocardiography, the prevalence of MAC was 23%. Mitral valve dysfunction was more than twice as prevalent in patients with MAC. Adjusted mortality was increased in patients with MAC and worse with both MAC and MVD. 相似文献
