International percutaneous coronary intervention complication survey.

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 21%, and 32% deployed at least one during the past year; 79% have never used fat to seal perforations; 64% have never used coils for perforations. Complications were attributed to higher patient/angiographic complexity by 68% and seen as opportunities for improvement by 70%; 97% of participants were interested in learning more about the management of PCI complications. The most useful learning methods were meetings (66%), webinars (48%), YouTube (32%), and Twitter (29%).

CONCLUSION

ICs who participated in the survey are highly concerned about complications. Following complication management algorithms and having access to more experienced operators might alleviate stress and optimize patient outcomes.
