What does PTCA stand for in cardiovascular procedures?

PTCA stands for Percutaneous Transluminal Coronary Angioplasty. This is a minimally invasive procedure used to open narrowed or blocked coronary arteries to improve blood flow to the heart. During PTCA, a catheter is inserted through the skin, typically in the groin or wrist, and advanced to the site of the blockage. A balloon on the catheter is then inflated to widen the artery, and often a stent is placed to keep the artery open.

The term "transluminal" refers to the procedure being performed across the lumen of a vessel, which is indicative of the technique used to navigate through the arterial system. This is crucial in the context of coronary intervention and highlights the innovative step forward in treating coronary artery disease.

The other options contain variations on the terms but do not accurately reflect the standard terminology recognized in medical practice for this procedure. The correct terminology ensures clarity in communication among medical professionals and helps maintain consistency in clinical documentation and procedures.
