OPCAB
Pronunciation: OP-cab
Also written as: OPCAB — off-pump coronary artery bypass
Off-pump coronary artery bypass surgery performed on a beating heart without cardiopulmonary bypass.
Full Definition
OPCAB (off-pump coronary artery bypass) is a surgical technique for performing coronary bypass surgery without stopping the heart or using cardiopulmonary bypass equipment. The procedure uses mechanical stabilizers to immobilize specific areas of the beating heart while maintaining perfusion to other regions. OPCAB reduces complications associated with bypass pumps, such as inflammatory responses and neurological risks, but requires advanced surgical skill and is not suitable for all patients or anatomical configurations.
Usage
Usage note: Distinguish clearly from conventional CABG in documentation.
