Abstract

Background PCI in CBL is common and technically demanding. Whether such patients have adverse outcome during the follow-up after successful PCI is unclear. We aim to compare the clinical outcome after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation of coronary bifurcation lesions (CBL) and non-CBL. Methods We performed a systematic literature search to identify studies reporting the clinical outcome of patients undergoing PCI in CBL or not. Patients with left main disease constituted a predefined subgroup. Primary study end-point was major adverse cardiac events (MACE). Results Fifteen publications on 23 891 patients with coronary artery disease treated by DES in CBL or not were identified. Median follow-up length was 24 months (range: 12-60). MACE at the longest available follow-up were significantly higher in CBL as compared with non-CBL (19.0 vs. 12.1%, P < 0.001). Similar results were obtained in the subanalysis restricted to second-generation DES studies. The MACE rate was higher early, then decreased during the follow-up being, however, appreciable at all timings up to 36 months. In the left main (LM) subanalysis (four studies, 3210 patients), patients underwent DES implantation in distal LM, as compared with nondistal LM, had increased the MACE rate during the follow-up (27.4 vs. 17.4%, P < 0.001), which was driven by higher target vessel revascularization. Conclusions In the contemporary DES era, CBL represent a subset of lesions associated with increased rate of MACE after PCI. This data prompt for studies aimed at improving the clinical outcomes of patients with CAD.
