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.
Angioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty (PTA), is a minimally invasive endovascular procedure used to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. A deflated balloon attached to a catheter is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. A stent may be inserted at the time of ballooning to ensure the vessel remains open, and the balloon is then deflated and withdrawn. Angioplasty has come to include all manner of vascular interventions that are typically performed percutaneously.
Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Andreas Gruentzig is considered the father of interventional cardiology after the development of angioplasty by interventional radiologist Charles Dotter.
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.
The University of Ottawa Heart Institute (UOHI) (French: Institut de cardiologie de l'Université d'Ottawa ) is Canada's largest cardiovascular health centre. It is located in Ottawa, Ontario, Canada. It began as a department in The Ottawa Hospital, and since has evolved into Canada's only complete cardiac centre, encompassing prevention, diagnosis, treatment, rehabilitation, research, and education.
A cardiovascular perfusionist, clinical perfusionist or perfusiologist, and occasionally a cardiopulmonary bypass doctor or clinical perfusion scientist, is a healthcare professional who operates the cardiopulmonary bypass machine during cardiac surgery and other surgeries that require cardiopulmonary bypass to manage the patient's physiological status. As a member of the cardiovascular surgical team, the perfusionist also known as the clinical perfusionist helps maintain blood flow to the body's tissues as well as regulate levels of oxygen and carbon dioxide in the blood, using a heart–lung machine.
Percutaneous coronary intervention (PCI) is a non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. The process involves combining coronary angioplasty with stenting, which is the insertion of a permanent wire-meshed tube that is either drug eluting (DES) or composed of bare metal (BMS). The stent delivery balloon from the angioplasty catheter is inflated with media to force contact between the struts of the stent and the vessel wall, thus widening the blood vessel diameter. After accessing the blood stream through the femoral or radial artery, the procedure uses coronary catheterization to visualise the blood vessels on X-ray imaging. After this, an interventional cardiologist can perform a coronary angioplasty, using a balloon catheter in which a deflated balloon is advanced into the obstructed artery and inflated to relieve the narrowing; certain devices such as stents can be deployed to keep the blood vessel open. Various other procedures can also be performed.
A coronary care unit (CCU) or cardiac intensive care unit (CICU) is a hospital ward specialized in the care of patients with heart attacks, unstable angina, cardiac dysrhythmia and various other cardiac conditions that require continuous monitoring and treatment.
Royal Papworth Hospital is a specialist heart and lung hospital, located on the Cambridge Biomedical Campus in Cambridgeshire, England. The Hospital is run by Royal Papworth Hospital NHS Foundation Trust.
The history of invasive and interventional cardiology is complex, with multiple groups working independently on similar technologies. Invasive and interventional cardiology is currently closely associated with cardiologists, though the development and most of its early research and procedures were performed by diagnostic and interventional radiologists.
Lourdes Heart Institute and Neuro Centre (LHINC) is a new block set up in Lourdes Hospital, Cochin, Kerala, India, to cater to tertiary level care for the entire spectrum of cardiovascular and neurological disease. It was inaugurated on 16 March 2007, by Mr. A. K. Antony, the Defence Minister of India. This institute was started to meet a long-felt need to provide cardiac and neurological interventional facilities, and especially to provide interventional neurological facilities for the treatment of strokes, including selective thrombolysis and primary angioplasty for stroke which was hitherto unavailable in this part of India.
MedStar Washington Hospital Center is the largest private hospital in Washington, D.C. A member of MedStar Health, the not-for-profit Hospital Center is licensed for 926 beds. Health services in primary, secondary and tertiary care are offered to adult and neonatal patients. It also serves as a teaching hospital for Georgetown University School of Medicine.
A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in the treatment of coronary heart disease. It is used in a procedure called percutaneous coronary intervention (PCI). Coronary stents are now used in more than 90% of PCI procedures. Stents reduce angina and have been shown to improve survival and decrease adverse events in an acute myocardial infarction.
St. Francis Hospital is a general medical and surgical hospital located in Columbus, Georgia, United States, and is accredited by the Joint Commission.
John S. Rumsfeld is an American cardiologist. He is the Chief Innovation Officer for the American College of Cardiology, and Professor of Medicine at the University of Colorado School of Medicine. He was previously the National Director of Cardiology for the U.S. Veterans Health Administration. Rumsfeld was named as Chief Innovation Officer for American College of Cardiology in 2015.
Richard Lee is a cardiac surgeon in St. Louis, Missouri, who helped pioneer a staged Hybrid Maze, a procedure for atrial fibrillation or AFIB. combining surgery and catheter based approaches.
