BACKGROUND: Intra-aortic balloon pumping (IABP) markedly increases graft flow after coronary artery bypass grafting (CABG) with cardiopulmonary bypass. We sought to delineate the effects of IABP on graft flow after off-pump CABG (OPCAB). METHODS: The clinical records of 32 patients (25 male, 7 female; mean age: 70 ± 9 years) who underwent OPCAB with IABP between January 2011 and May 2015 were retrospectively reviewed. Thirteen patients (41%) had a history of myocardial infarction, and 13 patients (41%) had a history of percutaneous coronary intervention...

BACKGROUND: The best management strategy for patients with coronary disease and mild to moderate AS requires the clinician to consider the operative risks of isolated coronary artery bypass grafting (CABG) against the risks of untreated aortic stenosis (AS). METHODS: Between 2000 and 2014, isolated off-pump CABG (OPCAB) was performed in 2023 patients. Of these patients, 103 presented with mild or moderate AS (mean age 72.7±6.3 years; 23 females), 96 (93.2%) presented with mild AS and seven (6...

Stroke is a major adverse event in patients developing atrial fibrillation (AF) after cardiac surgery. Surgical left atrial appendage amputation/ligation (LAA-A/L) during off-pump coronary artery bypass grafting (OPCAB) is routinely performed in our institution. We analyzed 578 consecutive patients (mean age 69 years, male 82%) undergoing OPCAB with or without concomitant LAA-A/L from 2011 to 2014 at our institution in a prospective observational manner. The safety and efficacy of the concomitant LAA-A/L on preventing early (<30 days) and overall postoperative stroke were examined...

In off-pump coronary artery bypass grafting(OPCAB), a bloodless operative field has great influence on the quality of anastomosis. In addition, maintenance of distal coronary flow during anastomosis stabilizes hemodynamics. We introduced a new intracoronary shunt cannula, Mini Shunt Pro (MSP). MSP adopts the step-tip, which allows easy insertion and reduces the risk of intimal injury. The distal and proximal sides of the tips of MSP are 0.25 mm different in diameter, which improves its fitness to the coronary artery and enhances a bloodless operative field...

Off-pump coronary artery bypass grafting (OPCAB) in patients with acute myocardial infarction (AMI) is difficult because of circulatory deterioration during displacement of the heart. At our institution, we performed minimally circulatory-assisted on-pump beating coronary artery bypass grafting (MICAB) in these patients. During MICAB, support flow was controlled at a minimal level to maintain a systemic blood pressure of approximately 100 mm Hg and a pulmonary arterial systolic pressure of <30 mm Hg, providing optimal pulsatile circulation for end-organ perfusion and prevention of heart congestion...

BACKGROUND: The long-term outcomes of off-pump coronary artery bypass grafting (CABG) are the subject of speculation. Our institution has >15 years of experience performing CABG both off-pump (OPCAB) and on cardiopulmonary bypass (CPB). Our null hypothesis was that there would be no difference in a long-term composite of death and revascularisation between the 2 methods. METHODS: We performed a retrospective cohort study of all isolated CABG at our institution from 2001 to 2015...

BACKGROUND: Postoperative atrial fibrillation (AF) is a common arrhythmia that occurs after coronary artery bypass grafting (CABG). New surgical techniques, particularly off-pump coronary artery bypass (OPCAB), are thought to be less invasive and results in fewer complications, i.e. AF, but available data are inconsistent. The aim of this study is to present the incidence and risk factors of AF in patients operated on with or without cardiopulmonary bypass. METHODS: We studied 1836 consecutive patients with stable coronary artery disease who were operated on with (CABG) or without (OPCAB) cardiopulmonary bypass...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become an alternative procedure for treating aortic stenosis (AS) in patients with advanced age and severe comorbidities. Ischemic heart disease (IHD) is present with AS in 40-50% of patients with typical angina. Considering the high operative mortality and morbidity rates in these patients, hybrid TAVI and off-pump CABG (OPCAB) have become realistic treatment options. METHODS AND RESULTS: Between August 2014 and November 2015, 12 patients were evaluated for simultaneous TAVI and OPCAB...

Due to long term patency, the internal mammary artery is considered as a conduit of choice for revascularization of the left anterior descending coronary artery. The internal mammary artery and its accessory branches in addition to perfusing the chest wall structures also contributes to supplying, part of the female breast arteries. In addition, due to the accompaniment of thoracic duct branches with the left internal mammary artery, harvesting may be associated with injury to these branches and contribute to chylothorax...

CONTEXT: One of the main limitations of off-pump coronary artery bypass grafting (OPCAB) is the occasional need for intraoperative conversion (IOC) to on-pump coronary artery bypass grafting. IOC is associated with a significantly increased risk of mortality and postoperative morbidity. The impact of IOC on outcome cannot be assessed by a randomized control design. AIMS: The objective of this study was to analyze the incidence, risk factors, and impact of IOC on the outcome in patients undergoing OPCAB...
