Background: Successful percutaneous coronary intervention for coronary lesions is limited by lower procedural success, higher periprocedural complications, higher restenosis rates and need for repeat revascularization. Various techniques with the use of one or two stents have been developed to optimize the treatment of this type of lesion. The purpose of the study was to determine the intraprocedural, in-hospital, and 6-month outcomes of patients with bifurcation lesions who underwent intervention in terms of procedural success, major adverse cardiac events, and target vessel revascularization; and to correlate the type of bifurcation intervention done with the intraprocedural, in-hospital and 6-month outcome of patients.
Methods: Between January 2009 and April 2009, 23 patients with bifurcation lesions (who fulfilled the inclusion criteria) underwent percutaneous coronary intervention. Patients were grouped according to the type of stent strategy used : Group 1 (n = 20) underwent provisional 1-stent strategy; and Group 2 (n = 3) underwent 2-stent bifurcation stenting. In-hospital and 6-month outcomes were determined.
Results: Group 1 had lower angiographic and procedural success rates than Group2. In-hospital stay was similar. However, due to the small study population size and low event rate, 6 month outcome could not be compared or the type of bifurcation stenting correlated with outcome.
Conclusions: No two bifurcations are identical, and no single strategy exists that can be applied to every bifurcation. The important issue in bifurcation PCI is the selection of the most appropriate strategy for an individual bifurcation and optimizing the performance of the technique.
