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]
Trial(s) | Intervention | Outcome |
---|---|---|
STRESS[2] (1994) |
PCI without stent | 20% (6 months)[2] |
STRESS[2] (1994) SIRIUS[3] (2003) TYPHOON[4] (2006) |
PCI with bare-metal stents | 14%[4]to 14% (6 months)[2] to 21% (270 days)[3] |
SIRIUS[3] (2003) TYPHOON[4] (2006) SPIRIT IV[5] (2010) |
PCI with first generation DES | 7%[4][5] to 9% (270 days)[3] |
SPIRIT IV[5] (2010) |
PCI with second generation DES | 4%[5] |
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
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]
