LEE ET AL.: Percutaneous Coronary Intervention Strategy for Bifurcation Lesions. True bifurcation lesion is frequently encountered in percutaneous coronary intervention. Because of the risk of acute closure after dilating the main branch lesion, intervention involving bifurcation lesion is associated with higher complication rate. Meanwhile, it is also associated with higher restenosis rate. Without anticipation and pre-defined intervention strategy, retrieval of compromised side branch after stenting the main branch may be problematic. The "Jailed Guidewire" technique was used in 32 patients with bifurcation lesions. The main branch was stented in all patients. Seven patients had stenting of both the main and side branches. Angiographic success was achieved in all main branches and in 84.4% of side branches. In-hosptial major adverse cardiac event (MACE) was 3.15% and the 6 month repeat revascularization rate was 15.6%.
