Transcatheter pulmonary valve replacement (TPVR), also known as percutaneous pulmonary valve implantation (PPVI), is the replacement of the pulmonary valve via catheterization through a vein. It is a significantly less invasive procedure in comparison to open heart surgery and is commonly used to treat conditions such as pulmonary atresia .
An external vascular closure device of radial artery following a Cardiac catheterization. The device allows for gradual release of pressure over the puncture site, reducing patient discomfort, until closure is achieved. Prior to the development of VCD's, the main method for closing the femoral artery was manual compression.
Stent technology improved rapidly, and in 1989 the Palmaz-Schatz balloon-expandable intracoronary stent was developed. [24] [25] Initial results with the Palmaz-Schatz stents were excellent when compared to balloon angioplasty, with a significantly lower incidence of abrupt closure and peri-procedure heart attack. [26]
A metal stent containing a valve is then deployed using a balloon to press the stent into the valve in effect opening the stenosed (or narrowed) valve and lodging the stent in place. The procedure was first approved in the United States in November 2011 [1] as an alternative for people deemed a poor candidate for open approach replacement ...
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").
Further diagnostic coronary angiography is not routinely indicated after coronary stent implantation. If progression of heart disease is suspected, a stress test will be performed; patients who develop symptoms or show evidence of ischemia in a stress test may undergo diagnostic cardiac re-catheterization. [35]
Endovascular procedure can be performed achieving access in to body’s arterial system from either femoral artery (in groin), brachial artery (in elbow) or radial artery in the wrist. The transfemoral (through groin) approach to perform cardiac catheterization has typically been more prevalent in invasive cardiology.
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). They are used in a medical procedure called percutaneous ...
