Cardiology is the study of the heart. Cardiology is a branch of medicine that deals with disorders of the heart and the cardiovascular system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease, and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery.
Coronary artery bypass surgery, also known as coronary artery bypass graft is a surgical procedure to treat coronary artery disease (CAD), the buildup of plaques in the arteries of the heart. It can relieve chest pain caused by CAD, slow the progression of CAD, and increase life expectancy. It aims to bypass narrowings in heart arteries by using arteries or veins harvested from other parts of the body, thus restoring adequate blood supply to the previously ischemic heart.
Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, is a congenital heart defect characterized by four specific cardiac defects. Classically, the four defects are:
Cardiopulmonary bypass (CPB) is a technique in which a machine temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and oxygen to the body. The CPB pump itself is often referred to as a heart-lung machine or "the pump". Cardiopulmonary bypass pumps are operated by perfusionists. CPB is a form of extracorporeal circulation. Extracorporeal membrane oxygenation is generally used for longer-term treatment.
Vascular surgery is a surgical subspecialty in which vascular diseases involving the arteries, veins, or lymphatic vessels, are managed by medical therapy, minimally-invasive catheter procedures and surgical reconstruction. The specialty evolved from general and cardiovascular surgery where it refined the management of just the vessels, no longer treating the heart or other organs. Modern vascular surgery includes open surgery techniques, endovascular techniques and medical management of vascular diseases - unlike the parent specialities. The vascular surgeon is trained in the diagnosis and management of diseases affecting all parts of the vascular system excluding the coronaries and intracranial vasculature. Vascular surgeons also are called to assist other physicians to carry out surgery near vessels, or to salvage vascular injuries that include hemorrhage control, dissection, occlusion or simply for safe exposure of vascular structures.
dextro-Transposition of the great arteries is a potentially life-threatening birth defect in the large arteries of the heart. The primary arteries are transposed.
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 ; to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, and atherosclerosis. It also includes heart transplantation.
Cardiac catheterization is the insertion of a catheter into a chamber or vessel of the heart. This is done both for diagnostic and interventional purposes.
Sir Magdi Habib Yacoub, is an Egyptian retired professor of cardiothoracic surgery at Imperial College London, best known for his early work in repairing heart valves with surgeon Donald Ross, adapting the Ross procedure, where the diseased aortic valve is replaced with the person's own pulmonary valve, devising the arterial switch operation (ASO) in transposition of the great arteries, and establishing the heart transplantation centre at Harefield Hospital in 1980 with a heart transplant for Derrick Morris, who at the time of his death was Europe's longest-surviving heart transplant recipient. Yacoub subsequently performed the UK's first combined heart and lung transplant in 1983.
The Rastelli procedure is an open heart surgical procedure developed by Italian physician and cardiac surgery researcher, Giancarlo Rastelli, in 1967 at the Mayo Clinic, and involves using a pulmonary or aortic homograft conduit to relieve pulmonary obstruction in double outlet right ventricle with pulmonary stenosis.
Transposition of the great vessels (TGV) is a group of congenital heart defects involving an abnormal spatial arrangement of any of the great vessels: superior and/or inferior venae cavae, pulmonary artery, pulmonary veins, and aorta. Congenital heart diseases involving only the primary arteries belong to a sub-group called transposition of the great arteries (TGA), which is considered the most common congenital heart lesion that presents in neonates.
The Norwood procedure is the first of three surgeries intended to create a new functional systemic circuit in patients with hypoplastic left heart syndrome and other complex heart defects with single ventricle physiology. The first successful Norwood procedure involving the use of a cardiopulmonary bypass was reported by Dr. William Imon Norwood, Jr. and colleagues in 1981.
The mini-maze procedures are cardiac surgery procedures intended to cure atrial fibrillation (AF), a common disturbance of heart rhythm. They are procedures derived from the original maze procedure developed by James Cox, MD.
A baffle is a surgically created tunnel or wall within the heart or major blood vessels used to redirect the flow of blood. They are used in some types of heart abnormalities that a child is born with known as congenital heart defects. Baffles are usually constructed, at least in part, from a person's own heart tissue, while other methods of redirecting blood using artificial material are known by the more generic term 'conduits'. Baffle does not refer to surgical techniques that redirect blood outside the heart or blood vessels such as coronary artery bypass grafting.
Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA).
The Mustard procedure was developed in 1963 by Dr. William Mustard at the Hospital for Sick Children in Toronto, Ontario, Canada.
Atrial septostomy is a surgical procedure in which a small hole is created between the upper two chambers of the heart, the atria. This procedure is primarily used to palliate dextro-Transposition of the great arteries or d-TGA, a life-threatening cyanotic congenital heart defect seen in infants. It is performed prior to an arterial switch operation. Atrial septostomy has also seen limited use as a surgical treatment for pulmonary hypertension. The first atrial septostomy was developed by Vivien Thomas in a canine model and performed in humans by Alfred Blalock. The Rashkind balloon procedure, a common atrial septostomy technique, was developed in 1966 by American cardiologist William Rashkind at the Children's Hospital of Philadelphia.
The Senning procedure is an atrial switch heart operation performed to treat transposition of the great arteries. It is named after its inventor, the Swedish cardiac surgeon Åke Senning (1915–2000), also known for implanting the first permanent cardiac pacemaker in 1958.
The LeCompte maneuver is a technique used in open heart surgery, primarily on infants and children. The maneuver entails cutting the main pulmonary artery and moving it anterior to the aorta before reattaching the pulmonary artery during the following reconstruction of the great vessels. It allows the surgeon to reconstruct the right ventricular outflow tract without needing to connect the proximal and distal sections with a graft. It also enables the surgeon to avoid compressing the coronary arteries and relieves compression of the bronchi in cases where the pulmonary artery is severely dilated or aneurysmal. If both pulmonary arteries are not mobilized adequately, they can become stretched, leading to pulmonic stenosis.
John D. Puskas is an American researcher, author, inventor and cardiovascular surgeon. As of 2022, he is Professor, Cardiovascular Surgery, Icahn School of Medicine at Mount Sinai, and chairman, Department of Cardiovascular Surgery at Mount Sinai Morningside, Mount Sinai Beth Israel and Mount Sinai West. He holds 11 U.S. patents and co-founded the International Coronary Congress and the International Society for Coronary Artery Surgery. He is credited by ResearchGate with 330 publications and 15,234 citations and as of 2022 Scopus reports an h-index of 62. Puskas is known for advancing coronary artery bypass (CABG) surgery by refining surgical techniques for all-arterial, off-pump CABG and inventing finer instruments to be used for advanced coronary bypass surgical procedures. He is credited with performing the first totally thoracoscopic bilateral pulmonary vein isolation procedure. He is the co-editor of State of the Art Surgical Coronary Revascularization, the first textbook solely devoted to coronary artery surgery.
