What is the most common procedure in the cath lab?

• A. Coronary angiogram
• B. Left ventriculography
• C. Pacemaker insertion
• D. Aortic valve replacement

Answer: (A)

The most common cath lab procedure is diagnostic coronary angiography. This test visualizes the coronary arteries by injecting contrast and taking X-ray images, allowing clinicians to see where blockages or narrowings exist. It serves as the frontline diagnostic step for suspected coronary artery disease and often determines the next move in treatment, whether that’s medical management or proceeding to an intervention. Because nearly all workups for chest pain or suspected CAD start with mapping the coronary arteries, this angiography is performed far more frequently than other procedures. The alternatives—pacemaker insertion, left ventriculography, or aortic valve replacement—are more specialized or less routinely needed. Pacemaker implantation is common in certain patient groups but not a universal cath lab procedure; left ventriculography is used selectively to assess ventricular function; and aortic valve replacement is a major intervention, done far less often than a standard diagnostic angiogram.
