Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart.This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks").
A pulmonary artery catheter (PAC), also known as a Swan-Ganz catheter or right heart catheter, is a balloon-tipped catheter that is inserted into a pulmonary artery in a procedure known as pulmonary artery catheterization or right heart catheterization.
A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures.
On October 30, 1958, while working in the Cardiac Laboratory on a 26-year-old patient with rheumatic heart disease, Sones was performing a procedure in which contrast dye was to be injected into the man's aorta. Just before the dye injection, Sones noticed that the catheter tip had inadvertently entered the man's right coronary artery. Sones ...
Various other procedures can also be performed at the same time. After a heart attack, it can be restricted to the culprit vessel (the one whose obstruction or thrombosis is suspected of causing the event) or complete revascularization; complete revascularization is more efficacious in terms of major adverse cardiac events and all-cause mortality.
Purse string sutures are placed in the aorta to prepare the insertions of the cannula into the aorta, and a catheter which temporarily arrests the heart using a solution high in potassium. Another purse string is placed in the right atrium for the venous cannula. Once the cannulas and the catheter are placed, cardiopulmonary bypass (CPB) is ...
Werner Theodor Otto Forßmann (Forssmann in English; German pronunciation: [ˈvɛʁnɐ ˈfɔʁsˌman] ⓘ; 29 August 1904 – 1 June 1979) was a German researcher and physician from Germany who shared the 1956 Nobel Prize in Medicine (with Andre Frederic Cournand and Dickinson W. Richards) for developing a procedure that allowed cardiac catheterization.
The history of invasive cardiology begins with the development of cardiac catheterization in 1711, when Stephen Hales placed catheters into the right and left ventricles of a living horse. [1] Variations on the technique were performed over the subsequent century, with formal study of cardiac physiology being performed by Claude Bernard in the ...
