cardiac catheterization
An invasive diagnostic procedure using catheters to visualize coronary arteries and assess cardiac function.
Full Definition
Cardiac catheterization is an invasive diagnostic procedure that involves threading thin, flexible tubes (catheters) through blood vessels to reach the heart. The procedure allows direct visualization of coronary arteries through contrast angiography, measurement of intracardiac pressures and oxygen saturations, and assessment of cardiac output. Left heart catheterization primarily evaluates coronary arteries and left ventricular function, while right heart catheterization assesses pulmonary circulation and right heart pressures. This procedure serves both diagnostic and therapeutic purposes, often preceding interventional procedures.
Usage
Usage note: Specify left or right heart catheterization when relevant; avoid abbreviating as 'cath' in formal reports.
