What does PCI stand for in cardiovascular interventions?

• A. Percutaneous Coronary Intervention
• B. Peripheral Circulatory Intervention
• C. Postoperative Cardiac Intervention
• D. Percussive Cardiac Intervention

Answer: (A)

PCI stands for Percutaneous Coronary Intervention. The key idea here is recognizing what the acronym means in cardiology. “Percutaneous” means through the skin, referring to how the procedure is done via a catheter inserted through a small skin puncture. “Coronary” points to the heart’s arteries that supply blood to the heart muscle. “Intervention” indicates a therapeutic procedure to open or widen a blocked artery and restore blood flow, typically accomplished with angioplasty and may include placing a stent.

This procedure is used to treat narrowed or blocked coronary arteries in conditions like angina or during a heart attack, helping to quickly improve blood flow and outcomes. The other options don’t fit because they don’t describe a catheter-based treatment of the heart’s arteries: peripheral circulatory intervention involves arteries outside the heart, postoperative cardiac intervention isn’t a standard term for this technique, and percussive cardiac intervention isn’t a real medical term.
