The first uses a cardiopulmonary bypass machine, a machine which takes over the functions of the heart and lungs during surgery by circulating blood and oxygen. With the heart in cardioplegic arrest , harvested arteries and veins are used to connect across problematic regions—a construction known as surgical anastomosis .
Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons.It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, [1] and ...
Open heart surgery is a procedure in which the patient's heart is opened and surgery is performed on the internal structures of the heart. It was discovered by Wilfred G. Bigelow of the University of Toronto that the repair of intracardiac pathologies was better done with a bloodless and motionless environment, which means that the heart should ...
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] As such it is an extracorporeal device. CPB is operated by a perfusionist. The ...
[1] [2] MICS CABG (Minimally Invasive Cardiac Surgery/Coronary Artery Bypass Grafting) or the McGinn technique is heart surgery performed through several small incisions instead of the traditional open-heart surgery that requires a median sternotomy approach, and can be performed in patients with multivessel coronary artery disease. [3]
Coronary artery bypass graft surgery has been in practice since the 1960s. Historically, vessels—such as the great saphenous vein in the leg or the radial artery in the arm—were obtained using a traditional "open" procedure that required a single, long incision from groin to ankle, or a "bridging" technique that used three or four smaller incisions.
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.
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.
