Percutaneous coronary intervention (PCI) includes transluminal balloon angioplasty (TBA) with or without stent implantation.
In most cases the stenting of the coronary arteries is the preferred endovascular method of revascularization in patients with coronary heart disease (CHD). To date, the data on the optimal choice of stent for coronary arteries of large diameter (> 5.0 mm) remain controversial, because the diameters of the arteries are close to the maximum size of coronary stents which exist at present. The problem of malposition of stents can lead to such complications as stent thrombosis in the intra- and postoperative periods especially in patients with ACS.
