Postoperative delirium (POD) is a common but serious complication after cardiac surgery and associated with various short- long-term outcomes. In this study, we investigated the effects of intraoperative glycemic variability (GV) other variables on POD surgery.A retrospective single-center cohort analysis was conducted using data from electronic medical record 2018 to 2020. A total 705 patients undergoing coronary artery bypass graft and/or valve surgery, aortic replacement were included in...
Abstract Atrio-esophageal fistula (AEF) is one of the most devastating complication radiofrequency catheter ablation (RFCA) atrial fibrillation (AF) and surgical repair strongly recommended. However, optimal approach remains to be elucidated. We retrospectively reviewed AEF cases that occurred after RFCA in a single center evaluated clinical results different approach. Surgical or endoscopic was attempted five AF patients who underwent RFCA. mediastinal infection not controlled patient...
Background:Patients with severe aortic stenosis (AS) are often found to have asymmetric septal hypertrophy (ASH). With low sensitivity of echocardiography for detecting dynamic left ventricular outflow tract (LVOT) obstruction in AS, we adopted a routine intraoperative inspection LVOT strategy valve replacement (AVR), and performed concomitant myectomy (CSM) as necessary. We sought (1) evaluate surgical outcomes CSM, (2) suggest preoperative echocardiographic parameters that correlate...
Background and Aim of the Study Although dopamine norepinephrine are recommended as first-line agents in treatment shock, it is unclear which optimal vasoactive inotropic agent (VIA) to manage postcardiotomy circulatory shock. This single-center, randomized clinical trial aimed investigate efficacy safety versus Methods We randomly assigned patients with shock receive either or norepinephrine. When persisted despite dose 20 μg/kg/min 0.2 norepinephrine, epinephrine vasopressin could be...
Fluid resuscitation is critical to perioperative maintenance of adequate preload and cardiac output after surgery. Liberal use saline, however, reportedly associated with an increased risk acute kidney injury (AKI) in critically ill patients. This study examined the effects high- versus low-volume saline administration on AKI surgery.In this retrospective study, we evaluated 1,740 consecutive patients who underwent surgery over a 2-year period. The were divided into high-volume (n=328,...
Objective Takotsubo syndrome following cardiac surgery is a rare occurrence. However, early diagnosis essential to prevent treatment which could increase the left ventricular outflow tract pressure gradient in patients with syndrome, and lead cardiogenic shock. Therefore, our study aimed identify incidence of after cardiopulmonary bypass associated risk factors prognosis. Methods We retrospectively studied 5773 who underwent between February 2007 July 2017. Among these, was diagnosed 52...
We present a patient with anomalous origin of the left coronary artery from pulmonary (ALCAPA), which was diagnosed and corrected in her 60 s.The is oldest documented survivor ALCAPA who underwent surgical repair.ALCAPA should be surgically to restore dual system at any age this case shows that procedure may performed safely even an elderly patient.
Background: B-type natriuretic peptide (BNP) is a biomarker predicting morbidity and mortality in patients with congestive heart failure. However, the usefulness of pre- or postoperative BNP levels undergoing cardiac surgery remains uncertain. We sought to determine association on under cardiopulmonary bypass (CPB). Methods: This study retrospectively evaluated 1,642 CPB over 2 years. The primary outcomes were 30-day overall after surgery. Results: rate was 3.0% (n=49), occurred 118 during...
Abstract Background We aimed to evaluate the effect of limited volume hydroxyethyl starch (HES) administration on postoperative renal function in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB). Methods One thousand six hundred fifty-seven CPB over two years were included. The divided according amount HES administrated during first 2 days post-surgery; moderate dose (≥20 ml/kg) versus low (< 20 ml/kg). Outcomes compared by using inverse probability weighting....
Abstract Background Despite advances in surgical and postoperative care, myocardial injury or infarction (MI) is still a common complication patients undergoing coronary artery bypass surgery (CABG). Several studies that aimed to reduce injury, including those investigating statin loading, have been conducted but did not indicate any clear benefits. Evolocumab, PCSK9 inhibitor, has reported lower lipids prevent ischemic events various medical conditions. However, the effect of evolocumab...
Background: Bypass grafting for chronic total occlusions (CTOs) remains surgically challenging and controversial.Therefore, we evaluated the incidence clinical outcomes of revascularization on CTOs undergoing coronary artery bypass (CABG).Methods: Among 828 patients who underwent isolated CABG from January 2010 to December 2018, 245 (29.6%) diagnosed with at least one CTO were included retrospectively reviewed.Primary endpoints 30-day overall mortality.Secondary endpoint was composite...
Objectives: Levosimendan is utilised for the treatment of low cardiac output after adult surgery. However, opinion regarding its benefit divided. Hence we performed a systematic review to answer this question. Methods: Systematic MEDLINE was (inception April 2014) identify randomised controlled trials comparing levosimendan and alternative therapy/placebo Pooled analysis obtain odds ratio (OR) using Peto method. Continuous data combined as weighted mean difference (WMD). Publication bias...
