Objectives: To investigate the perceptions of interventional cardiologists (IC) regarding the frequency, impact, and management strategies of percutaneous coronary intervention (PCI) complications.Background: The perceptions and management strategies of ICs of PCI complications have received limited study.Methods: Online survey on PCI complications: 46 questions were distributed via email lists and Twitter to ICs.Results: Of 11,663 contacts, 821 responded (7% response rate): 60% were from the United States and the median age was 46-50 years. Annual PCI case numbers were <100 (26%), 100-199 (37%), 200-299 (21%), and ≥300 (16%); 42% do not perform structural interventions, others reported performing <40 (30%), or >100 (11%) structural cases annually. On a scale of 0-10, participating ICs were highly concerned about potential complications with a median score of 7.2 (interquartile range: 5.0-8.7). The most feared complication was death (39%), followed by coronary perforation (26%) and stroke (9%). Covered stents were never deployed by
