Comparison of Procedural Complications and In-Hospital Clinical Outcomes Between Patients with Successful and Failed Percutaneous Intervention of Coronary Chronic Total Occlusions: A Meta-Analysis of Observational Studies

摘要

BackgroundMultiple attempts to pass guidewires and balloons across totally occluded segments may result in significant mechanical trauma and higher rates of coronary complications in patients undergoing PCI (percutaneous coronary intervention) for CTOs (chronic total occlusion). It is unknown whether these procedural complications affect short-term survival and in-hospital clinical outcomes after the PCI. The goal of this analysis was to clarify this issue by comparing the rates of adverse in-hospital clinical outcomes between successful and failed CTO-PCI groups.
