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.
Coronary artery bypass surgery aims to prevent death from coronary artery disease and improve quality of life by relieving angina, the associated feeling of chest pain. [1] The decision to perform surgery is informed by studies of CABG's efficacy in different patient subgroups, based on the lesions' anatomy or how well the heart is functioning.
This procedure makes heart surgery possible for patients who were previously considered too high risk for traditional surgery due to age or medical history. [5] [6] Patients referred for this procedure may have coronary artery disease (CAD); aortic, mitral or tricuspid valve diseases; or previous unsuccessful stenting.
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.
Totally endoscopic coronary artery bypass surgery (TECAB) is an entirely endoscopic robotic surgery used to treat coronary heart disease, developed in the late 1990s. It is an advanced form of minimally invasive direct coronary artery bypass surgery , which allows bypass surgery to be conducted off-pump without opening the ribcage.
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.
The lack of an adequate venous conduit is a relative contraindication to bypass surgery, and depending on the area of disease, alternatives may be used. Medical conditions such as ischemic heart disease or chronic obstructive pulmonary disease that increase the risk of surgery are also relative contraindications. For coronary and peripheral ...
Vascular bypass surgery such as coronary artery bypass surgery, a heart operation, in which the internal thoracic artery and great saphanous vein are used to bypass the coronary artery. [2] Cardiopulmonary bypass, a technique used in coronary artery bypass surgery. In on-pump bypass surgery, a heart-lung machine is used; in off-pump bypass ...
