Clinical and procedure characteristics in patients treated with polytetrafluoroethylene-covered stents after coronary perforation: a CIRC-8U multicenter registry and literature review

This study aimed at identifying the clinical characteristics and in-hospital outcomes of patients treated with polytetrafluorethylene (PTFE)-covered stents after coronary interventions in a multicenter registry. Subjects with coronary artery perforation were selected from 31,262 consecutive patients who underwent coronary interventions in the hospital registries. Subjects were divided into two groups: those with a PTFE-covered stent implantation and those without a PTFE-covered stent implantation. Clinical characteristics and in-hospital outcomes were compared between the two groups. Data for 82 consecutive coronary perforations (15 PTFE-covered stents and 67 non-PTFE-covered stents) were extracted from each hospital registry. The PTFE-covered stent group had a higher prevalence of perforations due to pre-dilatation before stenting or post-dilatation after stenting (80% vs. 10.4%;p <  0.001), more Ellis classification III perforations (66.6% vs. 28.4%;p = 0.019), longer perforation to hemostasis time (74 min vs. 10 min;p <  0.001), lower hemostatic success rates (73.3% vs. 94.0%;p = 0.015), and higher in-hospital mortality (26.7% vs. 6.0%;p = 0.015) than the non-PTFE-covered stent group. Although the prevalence of intravascular ultrasound (IVUS) usage was high during coronary interventions (86.7%), IVUS was performed in less than half the cases just before coronary perforations (47%) in the PTFE-covered stent group. Patients requi ring PTFE-covered...
