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...

Knowing a patient's cardiac output (CO) could contribute to a safe, optimized hemodynamic control during surgery. Precise CO measurements can serve as a guide for resuscitation therapy, catecholamine use, differential diagnosis, and intervention during a hemodynamic crisis. Despite its invasiveness and intermittent nature, the thermodilution technique via a pulmonary artery catheter (PAC) remains the clinical gold standard for CO measurements. LiDCOrapid™ (LiDCO, London, UK) and FloTrac/Vigileo™ (Edwards Lifesciences, Irvine, CA) are less invasive continuous CO monitors that use arterial waveform analysis...

Currently, the immediate extubation in the operating room is necessary for the patients undergoing off-pump coronary artery bypass (OPCAB). To achieve UFTA, anesthesiologists should control general anesthesia. We report the case series of UFTA for the patients undergone OPCAB at our hospital. Forty patients receiving OPCAB between April 2012 and April 2014 were retrospectively analyzed. We divided the patients into those extubated in the operating room (Extubation group) and those not (Intubation group). The extubation criteria included adequate revascularization, adequate hemostasis, ratio between Pa(O2) and FI(O2) more than 250, body temperature above 36 degrees C, stable hemodynamics without noradrenaline, without IABP, and normal postoperative chest X-ray...

We describe a simple method to fix the great saphenous vein graft (SVG) to the right coronary artery along the atrioventricular groove using fibrin glue in off-pump coronary artery bypass grafting (OPCAB). After completion of the proximal anastomosis, the SVG was placed along the atrioventricular groove to the acute margin. Fibrin glue was sprayed using pressurized carbon dioxide gas. A distal anastomosis was subsequently performed after rotating the heart to expose the posterior descending artery. It is a straightforward and reproducible technique to determine the optimal length of the SVG and prevent kinking or stretching of the graft, especially in OPCAB...
