Percutaneous transluminal coronary angioplasty
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.[2]
The relief from angina, as compared to relief from medical therapy, may be reduced when evidence-based medications are used.[3]
Stenting
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.[2]
Drug eluting stents can reduce restenosis rate[4], but should not be used if the patient cannot take clopidogrel.
Complications
Ventricular dysrhythmia during PTCA for myocardial infarction indicates an increased risk for mortality at 3 months.[5]
