All patients underwent off-pump CABG (OPCAB) including minimally invasive cardiac surgery (MICS-CABG)...

BACKGROUND: Remimazolam is a short-acting benzodiazepine with small circulatory depression. We used remimazolam for general anesthesia management in two very elderly patients undergoing hybrid surgery of transcatheter aortic valve implantation (TAVI) plus off-pump coronary artery bypass grafting (OPCABG). CASE PRESENTATION: A 96-year-old man (case 1) and a 92-year-old woman (case 2) had complex coronary artery disease (CAD) and severe aortic stenosis (AS) and were scheduled for TAVI plus OPCAB...

BACKGROUND: Maintaining a low left atrial pressure (LAP) in off-pump coronary artery bypass grafting (OPCAB) is desirable. This study was done to compare the effects of intravenous levosimendan or milrinone on LAP at different stages of OPCAB. MATERIALS AND METHODS: After institutional ethics committee clearance, this two-arm double-blind randomized control trial was done in 44 adult patients with triple vessel coronary artery disease undergoing OPCAB at cardiac OT of IPGME&R, Kolkata...

OBJECTIVES: In this study the authors have tried to examine the role of magnesium alone or in combination with diltiazem and / or amiodarone in prevention of atrial fibrillation (AF) following off-pump coronary artery bypass grafting (CABG). BACKGROUND: AF after CABG is common and contributes to morbidity and mortality. Various pharmacological preventive measures including magnesium, amiodarone, diltiazem, and combination therapy among others have been tried to lower the incidence of AF...

OBJECTIVE: To elucidate the association between phase angle (PA) and a composite adverse outcome in patients requiring off-pump coronary artery bypass grafting (OPCAB). DESIGN: A prospective observational study. SETTING: High-volume single center. PARTICIPANTS: A total of 229 adult patients who underwent OPCAB from May 2019 to October 2020. INTERVENTIONS: Each patient underwent bioelectrical impedance analysis, including PA assessment before surgery (PApre ), immediately postoperatively (PApost ), and 1 day postoperatively (PAPOD1 ), using an Inbody S10...

INTRODUCTION: Bioelectrical impedance analysis is a widely available, non-invasive method for body composition assessment. AIM: To elucidate the perioperative body composition alterations and their prognostic utility for hospital length of stay (LOS) in low risk, off-pump coronary artery bypass (OPCAB) patients. MATERIAL AND METHODS: Fifty patients undergoing elective OPCAB were included in the study. Body composition assessments were performed 1 day before the scheduled surgery and on the 6th postoperative day...

Background: Transfusion support has an essential role in coronary artery bypass graft (CABG). The time-honored gold standard for CABG is the on-pump procedure (ONCAB); however, off-pump coronary artery bypass (OPCAB) is also a safe, cost-benefit procedure with fewer blood transfusion requirements. This study was performed to evaluate transfusion patterns in OPCAB due to the diversity of transfusion practices. Materials and Methods: This retrospective study was performed to determine the transfusion rate and triggers in OPCAB patients...

Little is known regarding the long-term (> 10 years) outcomes and risk factors of total arterial coronary artery bypass grafting (CABG). This study evaluated the long-term outcomes and risk factors for all-cause mortality and major adverse cardiac and cerebrovascular events (MACCEs) following total arterial on-pump CABG (ONCAB) or off-pump CABG (OPCAB) with complete revascularization. This retrospective cohort analysis enrolled patients with stable angina who underwent total arterial CABG with complete revascularization in our institute between July 2000 and June 2019...

PURPOSE: Several technical aspects of the Fick method limit its use intraoperatively. A data-driven modification of the Fick method may enable its use in intraoperative settings. METHODS: This two-center retrospective observational study included 57 (28 and 29 in each center) patients who underwent off-pump coronary artery bypass graft (OPCAB) surgery. Intraoperative recordings of physiological data were obtained and divided into training and test datasets...

IMPORTANCE: Coronary artery bypass grafting (CABG) remains the gold standard for the treatment of multivessel and left main coronary heart disease. However, the current evidence about the optimal surgical revascularization strategy is inconsistent and is not sufficient to allow for definite conclusions. Thus, this topic needs to be extensively discussed. OBJECTIVE: The aim of this present study was to compare the clinical outcomes of off-pump CABG (OPCAB), conventional on-pump CABG (C-CABG) and on-pump beating heart (ONBEAT) CABG via an updated systematic review and network meta-analysis of randomized controlled trials (RCTs)...

OBJECTIVES: In this article, we present our initial clinical experience with staged minimally invasive direct coronary bypass (MIDCAB), percutaneous coronary intervention (PCI), and transcatheter aortic valve implantation (TAVI) in high-risk octogenarians (Hybrid). BACKGROUND: The use of percutaneous techniques for managing structural heart diseases, especially in elderly high-risk patients, has revolutionized the treatment of structural heart diseases. These procedures are present predominantly being offered as isolated interventions...

Platelet endothelial cell adhesion molecule 1 (PECAM-1) is considered an antiplatelet molecule. Previously, we introduced a new parameter called the PECAM-1/thrombus ratio, which indicates the proportion of PECAM-1 in the thrombus and provides a precise description of human platelet activity (in vitro). The aim of this study was to determine whether the PECAM-1/thrombus ratio could serve as a predictive factor for bleeding events during off-pump coronary artery bypass grafting (OPCAB). To achieve this, we collected blood samples from 20 patients scheduled to undergo OPCAB surgery...

BACKGROUND: There are limited studies reporting follow-up outcome data comparing of off-pump coronary artery bypass (OPCAB) with on-pump (ONCAB) technique. The aim of the study was to report the 5-year clinical outcomes of OPCAB and ONCAB in a post hoc analysis of the PROMOTE patency trial. METHODS: From March 2016 through March 2017, a total of 321 patients undergoing coronary artery bypass grafting (CABG) were randomised to either the off-pump or the on-pump technique...

BACKGROUND AND OBJECTIVE: The treatment of left main (LM) coronary artery disease (CAD) requires complex decision-making. Patients with left main multi-vessel coronary artery disease (LM CAD) have concerns regarding incomplete revascularization and reduced survival with off-pump (OPCAB) when compared with on-pump (ONCAB) coronary bypass surgery. To evaluate outcomes among high-risk LM CAD patients undergoing OPCAB, we performed a registry-based prospective study.
