Background: Left ventricular dysfunction (LVD) can occur immediately after mitral valve repair (MVr) for degenerative mitral regurgitation (DMR) in some patients with normal preoperative left ventricular ejection fraction (LVEF). This study investigated whether forward LVEF, calculated as left ventricular outflow tract stroke volume divided by left ventricular end-diastolic volume, could predict LVD immediately after MVr in patients with DMR and normal LVEF. Methods: Echocardiographic and clinical data were retrospectively evaluated in 234 patients with DMR ≥ moderate and preoperative LVEF ≥ 60%. LVD and non-LVD were defined as LVEF < 50% and ≥50%, respectively, as measured by echocardiography after MVr and before discharge. Results: Of the 234 patients, 52 (22.2%) developed LVD at median three days (interquartile range: 3–4 days). Preoperative forward LVEF in the LVD and non-LVD groups were 24.0% (18.9–29.5%) and 33.2% (26.4–39.4%), respectively (p < 0.001). Receiver operating characteristic (ROC) analyses showed that forward LVEF was predictive of LVD, with an area under the ROC curve of 0.79 (95% confidence interval: 0.73–0.86), and an optimal cut-off was 31.8% (sensitivity: 88.5%, specificity: 58.2%, positive predictive value: 37.7%, and negative predictive value: 94.6%). Preoperative forward LVEF significantly correlated with preoperative mitral regurgitant volume (correlation coefficient [CC] = −0.86, p < 0.001) and regurgitant fraction (CC = −0.98, p < 0.001), but not with preoperative LVEF (CC = 0.112, p = 0.088). Conclusion: Preoperative forward LVEF could be useful in predicting postoperative LVD immediately after MVr in patients with DMR and normal LVEF, with an optimal cut-off of 31.8%.

Objectives: Predictors of left ventricular dysfunction (LVD) after aortic valve replacement (AVR) in mixed aortic valve disease (MAVD) have not been studied. Objective was to determine prevalence and predictors of early and late LVD at 1 and 5 years post-AVR. Methods: Retrospective review of 247 patients (Age 63±8 years, males 81%) with moderate/severe MAVD who underwent AVR at the Mayo Clinic from 1994-2013. Only patients with follow-up data at 1 year post AVR were included (n=239). Cohort divided into 3 groups based on data collected prior to AVR, 1 and 5 years post AVR. LVD was defined as ejection fraction <50%. Results: LVD was present in 11/239 at baseline. At 1-year post AVR, 181 had normal EF (group 1) while 58/239 (24%) had early LVD (group 2). Predictors of LVD were atrial fibrillation (hazard ratio [HR] 1.83 confidence interval [CI] 1.59-1.98, p=0.001), age >70 years (HR: 3.12, CI: 2.33-4.18, p= <0.0001), CABG (HR: 2.17, CI: 2.24-5.93, p= <0.0001), and severe MAVD pre-operatively (HR: 2.87, CI: 2.33-3.17, p= 0.01), and hypertension (HR: 1.83, CI: 1.35-2.46, p= <0.0001). Prevalence of late LVD was 24% (47/197-group 3) and LVMI at 1 year post AVR was predictive of late LVD (HR 1.65, CI 1.11-3.8 per 10 g/ m 2 increment, p= 0.04)). Group 2 had less reverse LV remodeling compared to group 1 at 1 year post AVR (142±39 vs 129±42 g/ m 2 , p=0.02). Conclusions: Risk of LVD was significant even in subset of patients with moderate MAVD. Risk stratification of MAVD should be based on both clinical and echocardiographic parameters. Our data suggest earlier surgical intervention may be required in the MAVD population to prevent postoperative LVD but further studies are needed. Figure legend: FU: follow up
