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").
The first coronary care unit in the US was opened at Bethany Medical Center in Kansas City, Kansas by Hughes Day, and he coined the term. [3] [4] Bethany Medical Center is also where the first "crash carts" were developed. [5] Studies published in 1967 revealed that those observed in a coronary care setting had consistently better outcomes. [6]
A PCI involves performing a coronary angiogram to determine the location of the infarcting vessel, followed by balloon angioplasty (and frequently deployment of an intracoronary stent) of the stenosed arterial segment. In some settings, an extraction catheter may be used to attempt to aspirate (remove) the thrombus prior to balloon angioplasty.
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 patients suffering from coronary heart disease. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).
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.
Percutaneous coronary intervention (PCI) is a minimally invasive non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. [2] The procedure is used to place and deploy coronary stents, a permanent wire-meshed tube, to open narrowed coronary arteries. PCI is considered 'non-surgical ...
Cardiac nursing is a nursing specialty that works with patients who suffer from various conditions of the cardiovascular system. Cardiac nurses help treat conditions such as unstable angina , cardiomyopathy , coronary artery disease , congestive heart failure , myocardial infarction and cardiac dysrhythmia under the direction of a cardiologist.
Like metal stents, placement of a bioresorbable stent will restore blood flow and support the vessel through the healing process. However, in the case of a bioresorbable stent, the stent will gradually resorb and be benignly cleared from the body, enabling a natural reconstruction of the arterial wall and restoration of vascular function.
