Introduction Delirium after cardiac surgery is a devastating and important complication. https://www.selleckchem.com/products/PD-0332991.html Delirium is defined as "disturbance in attention (i.e., reduced ability to direct, focus, sustain, and shift attention) and awareness (reduced orientation to the environment)." In this study, we analyzed the association of preoperative vitamin D levels and postoperative delirium after cardiac surgery in patients over 65 years. Materials and methods We retrospectively reviewed the data of 212 adult patients above 65 years of age who underwent isolated coronary artery bypass graft surgery from January 2016 to January 2018. The mean age for Group I was 69.7 ± 7.4 and Group II was 70.6 ± 4.8 years. There were 112 female patients in Group I and 46 female patients in Group II. The patient population was divided into 2 groups based on preoperative serum vitamin D (25-hydroxyvitamin D [25-OHD]) levels (normal range of 25-75nmol/L). Group I included patients with preoperative serum 25-OHD level less then 25nmol/L. Group II includesary to confirm these results.Background This study compared the perioperative and follow-up period data of patients who underwent redo tricuspid valve replacements performed via thoracoscopic surgery or median sternotomy. link2 The purpose was to evaluate the feasibility, safety, and surgical outcomes of redo tricuspid valve replacement via uni-port thoracoscopic surgery. Methods Forty-nine patients with severe tricuspid valve regurgitation after left-side valve replacement underwent redo tricuspid valve replacements in our hospital from April 2012 to September 2019. Twenty-six patients underwent uni-port total thoracoscopy surgery, whereas 23 patients had the surgery performed via median sternotomy. We collected perioperative and 3- to 36-month postoperative data. Results No deaths occurred in the intraoperative period. Time of cardiopulmonary bypass in the study group significantly was longer than that in the control group (P less then .05), but the operative times in the study and control groups were not significantly different. Thoracic drainage, length of ICU stay, postoperative hospital stay, and complication rates in the study group were significantly different from those in the control group (P less then .05). Throughout the follow-up period, uni-port total thoracoscopic TVR was not inferior to traditional surgery with respect to cardiac function and recurrence of tricuspid valve regurgitation. Conclusions Uni-port total thoracoscopic tricuspid valve replacement is safe, feasible and effective, and that can be considered as a primary treatment strategy for patients with severe TR after previous left-sided valve procedure.Background Lower limb ischemia in patients with extracorporeal membrane oxygenation (ECMO) via femoral artery catheterization negatively affects patient mortality and survivors' quality of life [Gulkarov 2020]. In this study, ECMO was established via femoral artery catheterization. This study aimed to identify the risk factors of lower limb ischemia to provide sufficient evidence for its prevention. Methods All patients with venoarterial (VA) ECMO via femoral artery catheterization in Zhongshan People's Hospital from January 2008 to November 2019 retrospectively were analyzed. Patients' general information and ECMO-related information were obtained, and the main outcome variables were survival and discharge and intubation-related adverse events (limb ischemia and incision bleeding). Logistic regression analysis was used to determine the independent risk factors of limb ischemia in patients with VA ECMO. Results A total of 179 (98 [54.7%] men and 81 [45.3%] women) eligible patients were included in this study. Moreover, a total of 90 patients (48.9%) had low cardiac output, 41 (22.3%) had acute myocardial infarction, and 33 (17.9%) had fulminant myocarditis. Eighty-six (48.04%) patients survived to hospital discharge, 36 (20.11%) had limb ischemia, and 42 (23.46%) had incision bleeding. Furthermore, the ECMO-assisted time was 114.23 ± 67.88 hours. There was no significant difference in age, sex, and Sequential Organ Failure Assessment score between the limb ischemia group and the non-limb ischemia group. Multivariate logistic regression analysis showed that peripheral artery disease (odds ratio, 27.12; 95% confidence interval, 5.614-130.96) was an independent risk factor of limb ischemia in patients with ECMO. Conclusion Limb ischemia is a common complication in patients with VA ECMO, and peripheral artery disease is an independent risk factor of limb ischemia in patients with VA ECMO via femoral artery catheterization.Background While the surgical correction of moderate aortic stenosis (AS) can be deferred with a watchful waiting according to the present guideline, the clinical outcomes for moderate AS with comorbidity have not extensively been studied. We aimed to explore the factors that would contribute to the outcomes of moderate AS with at least five years of follow-up duration. Methods Medical records review identified patients with moderate aortic valve (AV) stenosis from January 2008 and December 2012. Echocardiographic data were gathered, and the final 5-year clinical outcomes, defined as the composite of cardiovascular (CV) death, admission for heart failure (HF) aggravation, and AV replacement, were evaluated. Results Among 148 patients (mean age, 69.3 years; mean AV area, 1.24 cm2), 79 had adverse outcomes (16 CV deaths, 32 AV replacements, and 31 HF cases), during a mean follow-up of 5.6 years. link3 The event group showed worse dyspnea of NYHA III-IV and a higher frequency of diabetes mellitus (DM). They had a higher frequency of moderate or moderate-to-severe functional mitral regurgitation (MR) and smaller AV area. In the multivariate analysis, DM (HR 2.29, 95% CI 1.03-5.10), moderate or moderate-to-severe MR (HR 4.84, 95% CI 1.66-10.07), and NYHA III-IV (HR 3.84, 95% CI 1.72-8.56) independently were associated with adverse outcomes. Conclusions The symptomatic patients with moderate AS had higher events than expected, and early intervention should be considered in case of concomitant MR and DM.Iatrogenic dissections of coronary artery and aorta is a rare and potentially fatal event, often following percutaneous coronary intervention (PCI). The prognosis of patients often depends on early accurate diagnosis and timely and effective treatment. There are no definite guidelines for the treatment of acute coronary artery dissection caused by PCI. Here, we report a 50-year-old patient with iatrogenic dissection of the right coronary artery and type A aortic dissection who underwent PCI for chest pain. We performed emergency surgery of right coronary artery ostium repair, aortic valvoplasty, ascending aorta replacement, and aortic arch descending stent implantation for the patient. The operation went smoothly, and the patient successfully was discharged two weeks after the operation.Background Out-of-center extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) implantation for the treatment of acute cardiorespiratory failure with subsequent transport to a tertiary care center has been introduced successfully into the medical practice. However, due to the very specific and resource intensive nature of this therapeutic concept, it seems important to generate algorithms for adequate patient selection. The aim of our study was to analyze the impact of patients' gender on early clinical outcome in this specific therapeutic scenario. Methods Ninety-seven consecutive patients treated by out-of-center ECMO/ECLS implantation and subsequent transport and treatment in our tertiary care cardiovascular center within the Hallesche Extracorporeal Life Support Program (HELP) retrospectively were analyzed, regarding the impact of patients' gender on early clinical outcome. Results Mechanical circulatory support successfully was weaned in two-thirds of the male patients. This result was achieved in only one-third of the female patients (59.4% in male vs. 33.3% in female, P = .0267). Overall survival significantly was higher in the male group (62.5% in male versus 30.3% in female, P = .0052). In uni- and multivariate logistic regression analysis, female gender was an independent predictor of in-hospital mortality (uni OR3.833, CI1.597-9.745, P = .0034; multi OR3.477, CI1.146-11.494, P = .0322). Worse outcome also was associated with following independent predictors, age, SOFA score, lactate and ventilation time pre-ECMO/ECLS implantation. Conclusion The current study demonstrates a worse early survival for women, following emergent out-of- center ECMO/ECLS implantation and subsequent transport and treatment in our tertiary care cardiovascular center. Gender should be included in patient selection algorithms while basic research approaches are needed to better understand the mechanisms underlying these gender- specific outcome disparities.Background The incidence of atherosclerotic cardiovascular diseases, which constitute an important disease group, is expected to rise with increasing life expectancy. The aim of this study was to investigate the predictive values of triglyceride/HDL cholesterol (TG/HDL-C) ratio and whole blood viscosity on possible severe carotid or peripheral arterial disease in patients who were admitted to our clinic and scheduled for coronary artery bypass graft (CABG) surgery. Methods This study retrospectively examined 299 patients who were admitted to our clinic and scheduled for CABG between August 1, 2015, and August 1, 2019. Patients with severe carotid or peripheral arterial disease were included in group 2; those in whom peripheral arterial disease and stenosis were not detected were included in group 1. Results Group 1 consisted of 255 patients, mean (± standard deviation) age 58.1 ± 8.9 years; the 44 patients in group 2 had a mean age of 64.1 ± 10.6 years (P = .018). The incidence of diabetes mellitus and tobacco use were significantly higher in group 2 (P less then .001 and P = .034, respectively). Triglyceride values, TG/HDL-C, and whole blood viscosity at high and low shear rates were significantly higher in group 2 (P = .017, P less then .001, P less then .001, and P less then .001, respectively). Receiver operator characteristic analysis revealed that the cutoff value of TG/HDL-C was 3.2 with 77% sensitivity and 72% specificity; that of high-shear-rate viscosity was 16.1 with 73% sensitivity and 69% specificity; and that of low-shear-rate viscosity was 59.2 with 70% sensitivity and 63% specificity. Conclusion It is possible to predict severe additional arterial diseases in patients scheduled for CABG with whole blood viscosity and TG/HDL-C ratios, both of which can be obtained with simple blood tests.Background Electrical cardioversion (ECV) often is required for terminating recurrent atrial fibrillation (AF) after surgical radiofrequency ablation in patients undergoing mitral valve surgery. However, ECV is unsuccessful in some cases. In this study, we aimed to identify possible predictors of failed ECV for recurrent atrial fibrillation following mitral valve surgery with concomitant radiofrequency ablation. Methods We enrolled 1,136 persistent AF patients with history of mitral valve surgery and concomitant radiofrequency ablation. Three-hundred-nineteen patients experienced recurrence of persistent AF and received ECV therapy. Comparison was made between patients with failed ECV (Failure group, N = 68) and successful ECV (Success group, N = 251). Results In multivariate regression analysis, age, pre-ECV loading-dose amiodarone, left atrial diameter, atrial flutter and time from surgery to ECV were independent predictors for outcomes of ECV. According to receiver operating characteristic curve analysis, the best threshold values of age, left atrial diameter and time from surgery to ECV for predicting failed ECV were 55.
