Off-pump coronary artery bypass (OPCAB), or beating-heart surgery, is a form of coronary artery bypass graft (CABG) surgery performed without cardiopulmonary bypass (heart-lung machine) as a treatment for coronary heart disease. It was primarily developed in the early 1990s by Dr. Amano Atsushi.
Minimally invasive direct coronary artery bypass (MIDCAB) is a surgical treatment for coronary heart disease that is a less invasive method of coronary artery bypass surgery (CABG). [1] MIDCAB gains surgical access to the heart with a smaller incision than other types of CABG.

Cognitive impairment has been reported in up to 80% cases after CABG at discharge and lasts for a year in up to 40% of cases. The cause remains unclear; CPB is an unlikely cause because even in CABG patients without CPB, as in off-pump CABG, and PCI patients, the incidence is the same. [38] [39]
Furthermore, the Van Dijk study showed no difference between the on-pump and off-pump groups in quality of life, stroke rate, or all-cause mortality at 3 and 12 months. A study by Jenson et al. published in Circulation found no significant difference in the incidence of cognitive dysfunction 3 months after either OPCAB or conventional on-pump CABG.
Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the circulation of blood and oxygen throughout the body. [1]
In coronary surgery, there are various alternatives to cardioplegia to perform the operation. One is off-pump coronary surgery where the surgery is done without the need of a cardiopulmonary bypass machine. Another is to use cross-clamp fibrillation whereby the heart fibrillates whilst on cardiopulmonary bypass in order to perform the distal ...
Vessel harvesting is a surgical technique that may be used in conjunction with a coronary artery bypass graft (CABG). For patients with coronary artery disease, a vascular bypass may be recommended to reroute blood around blocked arteries to restore and improve blood flow and oxygen to the heart.
