What is balloon angioplasty?
Balloon angioplasty or percutaneous coronary intervention (PCI) is a non-surgical procedure that employs percutaneous insertion and manipulation of a balloon catheter into the occluded coronary artery. The balloon is inflated to dilate the stenotic artery which causes endothelial damage, plaque fracture, medial dissection and haemorrhage in the affected arterial wall. PCI is accompanied with insertion of coronary stents in the blocked coronaries with a success rate of symptoms in over 95% cases. However, case selection for PCI is important and major indications are 2 or 3 vessel block but blockage of left main coronary is a contraindication for PCI. Unstable angioplasty may be associated with acute coronary syndromes. PCI is followed by administration of anti-platelet (oral aspirin) and antithrombin therapy to avoid occurrence of coronary thrombosis.
Recurrent stenosis after metal stenting in PCI may occur within 6 months in about 20% patients, more often in patients of diabetes mellitus. Restenosis is multifactorial in etiology that includes smooth muscle cell proliferation, extracellular matrix and local thrombosis. However, widespread use of drug-delivering stents has made it possible to overcome several long-term complications of coronary stenting. Currently, stents with anti-proliferative, anti-inflammatory, cytotoxic and cytostatic agents are commercially available.
