From 2009 to 2012, symptomatic patients who had severe coronary bifurcation stenoses were treated with one-stent strategy using drug-eluting stents, with kissing balloon inflation performed whenever side branch (SB) impingement occurred. TAP was performed if residual diameter stenosis of SB was ≥75%, presence of ≥type B dissection or flow impairment was observed in the SB. Seventy-one patients (83% male, mean age of 61±12years) were recruited into the study. MEDINA classification 1,1,1 lesions were observed in over 60% of patients. The mean stent size and length in the main vessel (MV) and SB were 2.86±0.43 and 30±12, and 2.45±0.26 and 16±6mm, respectively. Restudy angiography was performed on 64 (90%) patients at 9.2±3.9months. Angiographic restenosis was observed in 8 (12.5%) patients with late lumen loss in the MV and SB being 0.22±0.19 and 0.34±0.37mm, respectively. The use of TAP as the bailout technique for treating coronary bifurcation lesions is associated with good angiographic outcomes, in terms of late lumen loss and restenosis, at 9months.
