Abstract
BACKGROUND: Coronary artery perforation (CAP) is an uncommon but serious complication of percutaneous coronary intervention (PCI). The aim of this study was to compare early and late clinical outcomes of CAP in patients with or without acute coronary syndromes (ACS). METHOD: A retrospective review was made of the procedural records of 15 878 patients who underwent PCI at two large tertiary centers between January 2012 and December 2018. A total of 51 (0.32 %) CAP cases were identified. RESULTS: Of the 51 CAP cases, 26 (51.0%) patients had ACS and 25 (49%) patients had stable coronary artery disease (CAD). The major cause of perforation was stenting (43%). Cardiac tamponade was more frequent in the ACS group than stable CAD group (34.6 vs. 8%; P = 0.024). Kaplan-Meier analysis showed that the overall 30-day cardiovascular mortality rate was higher in patients with ACS than stable CAD (23.1 vs. 0%; P = 0.011). At the 3-year follow-up examination, no statistically significant difference was determined between the two groups in respect of all-cause mortality (36.1 vs. 28.4%; P = 0.262). Multivariable Cox regression analysis demonstrated left ventricular ejection fraction (hazard ratio, 0.94; 95% CI, 0.89-0.99; P = 0.033) but not ACS at presentation (hazard ratio, 1.39; 95% CI, 0.37-5.20; P = 0.628) as a predictor of mortality at 3 years. CONCLUSIONS: Early clinical outcomes following CAP, including cardiac tamponade and 30-day cardiovascular mortality, were significantly worse in patients with ACS compared to stable CAD.
