What cardiac revascularation procedure bypasses a blockage in a coronary artery without stopping the heart?

The cardiac revascularization procedure that bypasses a blockage in a coronary artery without stopping the heart is called off-pump coronary artery bypass grafting (OPCAB). In this technique, surgeons use specialized instruments to stabilize the heart and perform the bypass while it continues to beat. This approach minimizes the risks associated with cardiopulmonary bypass and can lead to quicker recovery times for patients.
