Left heart catheterization including intraprocedural injection(s) for left ventriculography, imaging supervision and interpretation, when performed with catheter placement in coronary artery(s) for coronary angiography

AI EXPLANATION: A left heart catheterization with coronary angiography is a diagnostic procedure used to evaluate how well your heart pumps and check for narrowed or blocked coronary arteries. During the procedure, a doctor gently guides a thin, flexible tube called a catheter through a blood vessel into the main pumping chamber of the heart and into the coronary arteries. A safe contrast dye is injected to take detailed X-ray images, allowing clinicians to view blood flow, measure heart chamber pressures, and pinpoint any blockages.
