'''Cardiac surgery''' is [[surgery]] on the [[heart]] and/or [[great vessel]]s performed by a [[cardiac surgeon]]. Frequently, it is done to treat complications of [[ischemic heart disease]] (for example, [[coronary artery bypass graft]]ing), correct [[congenital heart disease]], or treat [[valvular heart disease]] created by various causes including [[endocarditis]]. It also includes [[heart transplant]]ation.

==History==

==Operations under hypnosis==
The earliest operations on the [[pericardium]] (the sac that surrounds the heart) took place in the 19th century and were performed by, among others, [[Francisco Romero (surgeon)|Francisco Romero]],<ref>Aris A. Francisco Romero, the first heart surgeon. Ann Thorac Surg 1997 Sep;64(3):870-1. PMID 9307502</ref> [[Dominique Jean Larrey]], [[Henry Dalton]], and [[Daniel Hale Williams]]. The first successful surgery on the heart itself, performed without any complications, was by Dr. [[Ludwig Rehn]] of [[Frankfurt]], [[Germany]], who repaired a stab wound to the right [[Ventricle (heart)|ventricle]] on [[September 7]], [[1896]].
 
 
Surgery on the [[great vessels]] ([[aortic coarctation]] repair, [[Blalock-Taussig]] shunt creation, closure of [[patent ductus arteriosus]]), became common after the turn of the century and falls in the domain of cardiac surgery, but technically cannot be considered heart surgery.
 
 
===Closed heart surgery===
 
Surgery on the great vessels was followed by the development of ''closed heart surgery'', where the surgeon blindly worked on the beating heart. It left a great deal to be desired, but had much to offer for great risk. [[Palliation]] of severe [[mitral valve stenosis]], which was common in the past due to [[rheumatic fever]], could be accomplished by poking a finger into the (mitral) valve through an incision in the [[left atrium]].<ref>Bigelow WG. Cold Hearts: The Story of Hypothermia and the Pacemaker in Heart Surgery. McClelland and Stewart Limited. 1984. ISBN 0-7710-1414-7.</ref> If a finger didn't do, a knife was passed through the incision to cut out tissue. Following successful treatment of mitral stenosis, a special cutter for [[aortic valve stenosis]] was developed, that maneuvered through an incision in the left atrium, accomplished much the same thing as the surgeon's finger in a stenosed mitral valve.

It was soon discovered that the repair of intracardiac pathologies required a bloodless and motionless environment, which means that the heart should be stopped and drained of blood. The first successful intracardiac correction of a [[congenital heart defect]] using [[hypothermia]] was performed by Dr. [[C. Walton Lillehei]] and Dr. [[F. John Lewis]] at the University of Minnesota on [[September 2]], [[1952]]. The following year, Soviet surgeon [[Aleksandr Aleksandrovich Vishnevskiy]] conducted the first cardiac surgery under [[local anesthesia]].

Surgeons realized the limitations of hypothermia - complex intracardiac repairs take more time and the patient needs blood flow to the body (and particularly the brain); the patient needs the function of the heart and lungs provided by an artificial method, hence the term [[cardiopulmonary bypass]]. Dr. [[John Heysham Gibbon]] at Jefferson Medical School in Philadelphia reported in 1953 the first successful use of extracorporeal circulation by means of an [[oxygenator]], but he abandoned the method, disappointed by subsequent failures. In 1954 Dr. Lillehei realized a successful series of operations with the [[controlled cross-circulation technique]] in which the patient's mother or father was used as a '[[heart-lung machine]]'. Dr. [[John W. Kirklin]] at the [[Mayo Clinic]] in Rochester, Minnesota started using a Gibbon type pump-oxygenator in a series of successful operations, and was soon followed by surgeons in various parts of the world.

This is a surgery in which the patient chest is opened and surgery is performed on the heart. The term "open" refers to the chest, not to the heart itself. The heart may or may not be opened depending on the particular type of surgery.

Since the 1990s, surgeons have begun to perform "[[OPCAB|off-pump bypass surgery]]" - coronary artery bypass surgery without the aforementioned [[cardiopulmonary bypass]]. In these operations, the heart is beating during surgery, but is stabilized to provide an (almost) still work area. Some researchers believe this approach results in fewer post-operative complications (such as [[postperfusion syndrome]]) and better overall results (studies results are controversial as of 2007, surgeon's preference and hospital results still play a major role).

A new form of heart surgery that has grown in popularity is robotic heart surgery. This is where a machine is used to perform surgery while being controlled by the heart surgeon. The main advantage to this is the size of the incision made in the patient. Instead of an incision being at least big enough for the doctor to put his hands inside, it does not have to be bigger than 3 small holes for the robot's much smaller hands to get through. Also, a major advantage to the robot is the recovery time of a patient, instead of 6 months of recovery time, some patients have recovered and resumed playing athletics in a matter of weeks.{{Fact|date=September 2007}}

Heart surgery or Cardiac surgery is surgery on the heart and/or great vessels performed by a cardiac surgeon. Frequently, it is done to treat complications of ischemic heart disease (for example, coronary artery bypass grafting), correct congenital heart disease, or treat valvular heart disease created by various causes including endocarditis. It also includes heart transplantation.

It was soon discovered that the repair of intracardiac pathologies required a bloodless and motionless environment, which means that the heart should be stopped and drained of blood.
