In medicine, percutaneous transluminal coronary angioplasty (PTCA), also called percutaneous coronary intervention (PCI), is a form of myocardial revascularization in which occurs "dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply."[1]

PTCA may be a treatment for myocardial infarction and an intravascular stent may or may not be left at the site of the stenosis in order to prevent restenosis.[6]

The relief from angina, as compared to relief from medical therapy, may be reduced when evidence-based medications are used.[7]

Stenting

For more information, see: Stent.
Insertion of the stent on the delivery catheter, expansion of the stent, and lastly appearance after withdrawal of the delivery catheter.

Stenting reduces the rate of restenosis, but should not be done if the patient has extensive stenoses, the stenosis is in a very small coronary artery, or if bypass surgery is planned within a few days.[6]

Drug eluting stents can reduce restenosis rate[4], but should not be used if the patient cannot take clopidogrel.

Effectiveness

Clinical practice guidelines address management and selection of patients.[8]

Complications

Ventricular dysrhythmia during PTCA for myocardial infarction indicates an increased risk for mortality at 3 months.[9]
