<p><b>Objective:</b> We retrospectively evaluated the results of an edge-to-edge repair (Alfieri stitch) of the mitral valve performed via a transaortic approach in patients who were undergoing minimally invasive aortic valve replacement.</p><p><b>Methods:</b> From January 2010 to September 2010, 6 patients underwent minimally invasive edge-to-edge repair of the mitral valve via a transaortic approach with concomitant aortic valve replacement. The patients were considered to be candidates for this procedure if they were deemed by the surgeon to be high-risk for a double valve procedure and if on preoperative transesophageal echocardiogram the mitral regurgitation jet originated from the middle portion (A2/P2 segments) of the mitral valve.</p><p><b>Results:</b> There was no operative mortality. Mean cardiopulmonary bypass time was 137 minutes, and mean cross-clamp time was 111 minutes. There was a significant improvement in the mean mitral regurgitation grade, with a mean of 3.8 preoperatively and 0.8 postoperatively. The ejection fraction remained stable, with mean preoperative and postoperative ejection fractions of 43.3% and 47.5%, respectively. Follow-up transthoracic echocardiograms obtained at a mean of 33 days postoperatively (range, 8-108 days) showed no significant worsening of mitral regurgitation.</p><p><b>Conclusion:</b> Transaortic repair of the mitral valve is feasible in patients undergoing minimally invasive aortic valve replacement.</p>

Abstract Background/objectives Pericoronary adipose tissue inflammation might lead to the development and destabilization of coronary plaques in prediabetic patients. Here, we evaluated inflammation and leptin to adiponectin ratio in pericoronary fat from patients subjected to coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI). Furthermore, we compared the 12-month prognosis of prediabetic patients compared to normoglycemic patients (NG). Finally, the effect of metformin therapy on pericoronary fat inflammation and 12-months prognosis in AMI-prediabetic patients was also evaluated. Methods An observational prospective study was conducted on patients with first AMI referred for CABG. Participants were divided in prediabetic and NG-patients. Prediabetic patients were divided in two groups; never-metformin-users and current-metformin-users receiving metformin therapy for almost 6 months before CABG. During the by-pass procedure on epicardial coronary portion, the pericoronary fat was removed from the surrounding stenosis area. The primary endpoints were the assessments of Major-Adverse-Cardiac-Events (MACE) at 12-month follow-up. Moreover, inflammatory tone was evaluated by measuring pericoronary fat levels of tumor necrosis factor-α (TNF-α), sirtuin 6 (SIRT6), and leptin to adiponectin ratio. Finally, inflammatory tone was correlated to the MACE during the 12-months follow-up. Results The MACE was 9.1% in all prediabetic patients and 3% in NG-patients. In prediabetic patients, current-metformin-users presented a significantly lower rate of MACE compared to prediabetic patients never-metformin-users. In addition, prediabetic patients showed higher inflammatory tone and leptin to adiponectin ratio in pericoronary fat compared to NG-patients (P < 0.001). Prediabetic never-metformin-users showed higher inflammatory tone and leptin to adiponectin ratio in pericoronary fat compared to current-metformin-users (P < 0.001). Remarkably, inflammatory tone and leptin to adiponectin ratio was significantly related to the MACE during the 12-months follow-up. Conclusion Prediabetes increase inflammatory burden in pericoronary adipose tissue. Metformin by reducing inflammatory tone and leptin to adiponectin ratio in pericoronary fat may improve prognosis in prediabetic patients with AMI.

Background Prior studies showed that life expectancy in patients who underwent surgical aortic valve replacement (AVR) was lower than in the general population. Explanations for this shorter life expectancy are unknown. The aim of this nationwide, observational cohort study was to investigate the cause‐specific death following surgical AVR. Methods and Results We included 33 018 patients who underwent primary surgical AVR in Sweden between 1997 and 2018, with or without coronary artery bypass grafting. The SWEDEHEART (Swedish Web‐System for Enhancement and Development of Evidence‐Based Care in Heart Disease Evaluated According to Recommended Therapies) register and other national health‐data registers were used to obtain and characterize the study cohort and to identify causes of death, categorized as cardiovascular mortality, cancer mortality, or other causes of death. The relative risks for cause‐specific mortality in patients who underwent AVR compared with the general population are presented as standardized mortality ratios. During a mean follow‐up period of 7.3 years (maximum 22.0 years), 14 237 (43%) patients died. The cumulative incidence of death from cardiovascular, cancer‐related, or other causes was 23.5%, 8.3%, and 11.6%, respectively, at 10 years, and 42.8%, 12.8%, and 23.8%, respectively, at 20 years. Standardized mortality ratios for cardiovascular, cancer‐related, and other causes of death were 1.79 (95% CI, 1.75–1.83), 1.00 (95% CI, 0.97–1.04), and 1.08 (95% CI, 1.05–1.12), respectively. Conclusions We found that life expectancy following AVR was lower than in the general population. Lower survival after AVR was explained by an increased relative risk of cardiovascular death. Future studies should focus on the role of earlier surgery in patients with asymptomatic aortic stenosis and on optimizing treatment and follow‐up after AVR.

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
