OPCAB

Pronunciation: OP-kab

Also written as: OPCAB — Off-Pump Coronary Artery Bypass

Coronary artery bypass surgery performed on the beating heart without cardiopulmonary bypass.

Full Definition

Off-pump coronary artery bypass is a surgical technique that allows coronary revascularization on the beating heart without the use of cardiopulmonary bypass. OPCAB procedures require specialized anesthetic management including careful positioning, hemodynamic optimization during vessel manipulation, and management of cardiac displacement. This approach may reduce complications associated with cardiopulmonary bypass but requires extensive experience from both surgical and anesthetic teams.

Usage

Usage note: Distinguish from other minimally invasive cardiac procedures in documentation.
