Abstract

OBJECTIVES: We sought to examine contemporary perspectives and practices on chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: The frequency and success of CTO-PCI have been increasing in recent years. METHODS: An online questionnaire was created and distributed to cardiologists within the United States and internationally. RESULTS: A total of 1149 responses were obtained. The United States (n ≤ 845; 73.5%), Asia (n ≤ 98; 8.5%), Europe (n ≤ 88; 7.7%), South America (n ≤ 42; 3.7%), and Canada (n ≤ 33; 2.9%) accounted for most responses. Mean practice duration of the respondents was 16.4 ± 11.5 years and 66.9% were interventional cardiologists. Most respondents agreed that CTO-PCI results in an improvement of patient symptoms (90.7%), left ventricular function (79.3%), arrhythmia risk (69.2%), and overall survival (63.1%). Interventional cardiologists had a more favorable view of the benefits of CTO-PCI as compared with non-interventional cardiologists (P<.001). Most respondents estimated the procedural success rates of contemporary CTO-PCI to be between 51%-75% (34.2%) and 76%-85% (30.2%), with interventional cardiologists estimating higher success rates than non-interventionalists (P<.001). Perforation, mortality, and tamponade were the three most concerning complications. Time and procedure complexity were reported to be the most significant barriers to the development of a CTO-PCI program. CONCLUSIONS: Most cardiologists believe that CTO-PCI can provide significant clinical benefits and can be accomplished with moderate to high success rates. Interventional cardiologists have a more favorable view of CTO-PCI as compared with non-invasive cardiologists.
