Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

3.4K
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
