AIM: Percutaneous coronary intervention (PCI) of chronic total occlusions (CTO) is common even with concomitant multivessel disease. We aimed to investigate the impact of multivessel disease on long-term outcome after PCI for CTO. METHODS: We collected baseline, procedural and follow-up data on patients undergoing successful PCI with stenting for CTO. We divided our population into three groups: patients with 1 vessel disease (1VD), those with 2-vessel disease (2VD) and subjects with 3-vessel disease (3VD). The primary end-point was the occurrence of major adverse cardiac events (MACE), i.e. death, myocardial infarction or target vessel revascularization. RESULTS: A total of 111 patients were included: 24 (21%) in group 1VD, 28 (25%) in group 2VD, and 59 (53%) in group 3VD. Clinical follow-up was available in 109 (98%) of them after a median of 27 months (range 6-68), yielding MACE rates of 1 (4%) in group 1VD, 5 (18%) in group 2VD, and 17 (29%) in group 3VD, respectively (P=0.03). No statistically significant difference was found comparing the 3 groups for the individual rates of death, myocardial infarction or target vessel revascularization (all P>0.05). No case of definite or probable stent thrombosis was adjudicated, despite use of DES in 99 (89%) patients. CONCLUSION: Patients with diffuse coronary disease undergoing PCI for a CTO fare a significantly worse prognosis. Nonetheless, despite liberal use of DES, stent thrombosis is rare in this setting, without differences according to the initial severity of disease, thus supporting the long-term safety of DES, even if used in this "off-label" context.

Abstract

AIM: Percutaneous coronary intervention (PCI) of chronic total occlusions (CTO) is common even with concomitant multivessel disease. We aimed to investigate the impact of multivessel disease on long-term outcome after PCI for CTO. METHODS: We collected baseline, procedural and follow-up data on patients undergoing successful PCI with stenting for CTO. We divided our population into three groups: patients with 1 vessel disease (1VD), those with 2-vessel disease (2VD) and subjects with 3-vessel disease (3VD). The primary end-point was the occurrence of major adverse cardiac events (MACE), i.e. death, myocardial infarction or target vessel revascularization. RESULTS: A total of 111 patients were included: 24 (21%) in group 1VD, 28 (25%) in group 2VD, and 59 (53%) in group 3VD. Clinical follow-up was available in 109 (98%) of them after a median of 27 months (range 6-68), yielding MACE rates of 1 (4%) in group 1VD, 5 (18%) in group 2VD, and 17 (29%) in group 3VD, respectively (P=0.03). No statistically significant difference was found comparing the 3 groups for the individual rates of death, myocardial infarction or target vessel revascularization (all P>0.05). No case of definite or probable stent thrombosis was adjudicated, despite use of DES in 99 (89%) patients. CONCLUSION: Patients with diffuse coronary disease undergoing PCI for a CTO fare a significantly worse prognosis. Nonetheless, despite liberal use of DES, stent thrombosis is rare in this setting, without differences according to the initial severity of disease, thus supporting the long-term safety of DES, even if used in this "off-label" context.
