Clinical outcome after percutaneous coronary intervention with drug-eluting stent in bifurcation and nonbifurcation lesions: A meta-analysis of 23 981 patients
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.
