cardiac catheterization
An invasive diagnostic procedure using catheters inserted into the heart's chambers or vessels to measure pressures and visualize anatomy.
Full Definition
Cardiac catheterization is a gold-standard invasive procedure performed in a catheterization laboratory where thin, flexible tubes (catheters) are threaded through blood vessels to the heart. The procedure allows direct measurement of intracardiac pressures, assessment of cardiac output, evaluation of valve function, and visualization of coronary anatomy through contrast injection. Both diagnostic and therapeutic interventions can be performed during the same procedure. The technique requires specialized training and carries inherent risks including bleeding, infection, and contrast reactions.
Usage
Usage note: Distinguish from electrophysiology studies and ablation procedures, which use different catheter types and techniques.
