PTCA
Also written as: PTCA — Percutaneous Transluminal Coronary Angioplasty
Percutaneous transluminal coronary angioplasty, the original balloon-only technique for opening blocked coronary arteries.
Full Definition
PTCA refers to percutaneous transluminal coronary angioplasty, the foundational interventional cardiology procedure developed in the 1970s. This technique involves inflating a balloon catheter within a narrowed coronary artery to compress atherosclerotic plaque and restore blood flow. While largely superseded by stent implantation in modern practice, PTCA remains relevant in specific clinical scenarios such as very small vessels, acute settings where rapid reperfusion is needed, or when stent placement is contraindicated. The term is still frequently used in medical literature and billing codes.
Usage
Usage note: Distinguished from PCI, which typically implies stent placement.
