Predictors of major adverse cardiovascular events in patients with coronary artery perforation treated with covered stents
- Department of Cardiology, Medipol Mega University Hospital, Faculty of Medicine, Istanbul, Turkey
Background: Coronary artery perforation (CAP) is a rare, life-threatening complication of percutaneous coronary intervention (PCI). PTFE-coated stents are highly successful and lifesaving in the treatment of coronary perforation. The incidence of thrombosis and restenosis in the PTFE-covered stent is higher than in standard stents. The aim of this study was to evaluate the clinical outcomes of PTFE-covered stents for CAP.
Materials and methods: We evaluated a total of 38 patients who were treated with PTFE-coated stents for coronary perforation from January 2012 to January 2022 at a single high-volume center, Medipol University Hospital in Turkey. The primary endpoint was the composite of major adverse cardiovascular events (MACEs).
Results: The one-year outcomes of the patients who had PTFE-coated stents implanted after CAP were investigated. A total of 38 patients, 22 (58%) males and 16 (42%) females, were included. The mean age was 69.7±11.4 years. MACE developed in 37% of the population (14 patients) in the follow-up. The target vessel revascularization (TVR) rate at one year was 36.8% (14 patients), the target lesion revascularization (TLR) rate at one year was 21% (8 patients), the incidence of death was 10.5% (4 patients), of myocardial infarction 21.1% (8 patients).
Conclusions: Today, although the majority of coronary perforation cases are successfully treated with PTFE-coated stents, the one-year outcome of MACE in CS implanted patients is high. These results showed that such patients should be closely monitored.
