Insights
Coronary artery perforation during PCI is serious. A polytetrafluoroethylene-coated stent graft (CSG) effectively sealed perforations in a large multicenter study, avoiding major adverse events.
Area of Science:
- Interventional Cardiology
- Cardiovascular Research
- Medical Device Technology
Background:
- Coronary artery perforation is a rare but severe complication of percutaneous coronary intervention (PCI).
- Traditional treatments for coronary perforation carry high risks of mortality, myocardial infarction, and emergency surgery.
- Limited data exists on the efficacy of stent grafts for sealing coronary perforations.
Purpose of the Study:
- To evaluate the outcomes of using the JOSTENT coronary stent graft (CSG) in patients with coronary artery perforations.
- To assess the safety and effectiveness of CSG in managing severe coronary perforations complicating PCI.
Main Methods:
- A retrospective analysis of an international registry involving 41 patients with coronary perforations.
- Polytetrafluoroethylene-coated JOSTENT coronary stent grafts (CSGs) were used to treat the perforations.
- Outcomes including perforation sealing, procedural success, and in-hospital complications were analyzed.
Main Results:
- The study included severe perforations (29.1% Ellis grade 3).
- 52 CSGs were successfully deployed in 41 patients, sealing 92.9% of perforations completely and 7.1% partially.
- The overall procedure success rate was 96.4%, with no in-hospital Q-wave myocardial infarctions, emergency bypass surgeries, or deaths.
Conclusions:
- The polytetrafluoroethylene-coated JOSTENT coronary stent graft (CSG) is a reliable and highly effective option for sealing coronary perforations.
- CSG implantation significantly reduces the risk of severe complications associated with coronary artery perforation during PCI.
- This multicenter series supports the use of CSG as a primary treatment for coronary perforations.
Abstract:
Coronary artery perforation is a rare, but dreaded, complication of percutaneous coronary intervention. Conventional treatment, including reversal of anticoagulation and prolonged balloon inflation, is associated with a high incidence of death, Q-wave myocardial infarction, and emergency coronary bypass surgery. Although a number of case reports have demonstrated the feasibility of sealing coronary perforations with synthetic material-covered stent grafts, the efficacy of this treatment has not been reported in a large, multicenter series. We used a retrospective international registry to examine the outcomes of the polytetrafluoroethylene-coated JOSTENT coronary stent graft (CSG) in 41 cases of coronary perforations. Perforations were relatively severe: 16.7% Ellis grade 1, 54.2% grade 2, and 29.1% grade 3. Of the 41 patients, > 1/3 (n = 14) experienced life-threatening complications before stent graft implantation, including pericardial tamponade (12.2%), cardiogenic shock (9.8%), and cardiac arrest (2.4%). A total of 52 CSGs were used to treat the 41 perforations (mean 1.3 per lesion). All CSGs were placed successfully, with 92.9% of the perforations sealed completely and 7.1% partially. One patient developed abrupt vessel closure after CSG deployment, resulting in an overall procedure success rate of 96.4%. No in-hospital Q-wave myocardial infarctions, emergency coronary bypass surgeries, or deaths resulted. The CSG may be a reliable and highly effective treatment option for sealing coronary perforations complicating percutaneous coronary interventions.
