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.
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.
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 .
The technique uses devices to support the surrounding heart tissues while vital surgery takes place. This is also known as off-pump CABG (OPCAB). OPCAB voids the use of cardiopulmonary bypass (CPB), which requires the heart to be stopped (arrested) with cardioplegia solution. Off-pump is also known as beating heart surgery. [citation needed]
Wenner Dudley Johnson (April 3, 1930 – October 24, 2016) was an American cardiothoracic surgeon who became known as the father of coronary artery bypass surgery.He and a colleague operated on one of the longest-surviving patients in the early days of heart transplants, and he made significant contributions to several other cardiac surgical procedures.
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 ...
In on-pump bypass surgery, a heart-lung machine is used; in off-pump bypass surgery, the surgeon stabilizies the heart without use of the machine.

On June 24, 2024, Lamelas was mentioned specifically by the Department of Justice in Medicaid fraud. Specifically, he was named as one of the "three heart surgeons who performed at St. Luke’s - engaged in a regular practice of running two operating rooms at once and delegating key aspects of extremely complicated and risky heart surgeries to unqualified medical residents."
