Objectives: To evaluate the outcome of patients with coronary perforations who were treated with the dual catheter approach.
Background: Coronary artery perforation is a grave complication of percutaneous coronary intervention (PCI) with high mortality and morbidity. Treating a coronary artery perforation with two catheters through dual access enables a rapid delivery of covered stent or coils to the vessel, without losing control of the perforation site.
Methods: We retrospectively reviewed all patients who had a severe coronary perforation during a PCI in our center, and compared outcomes of patients treated with the dual versus the traditional single guiding catheter approach.
Results: Between April 2004 and October 2008, 13,466 PCI's were performed in Columbia University - New York Presbyterian Medical Center. There were 33 documented cases of coronary perforations during that period of time (0.245%), among these, 26 were angiographically severe (Ellis type 2 or 3 perforations). Eleven patients were treated acutely with a dual catheter technique whereas the other fifteen patients were treated using a single guiding catheter. In the dual catheter group one patient expired after emergent CABG (9.1%), and four patients underwent emergent paricardiocentesis (36.4%). In patients treated with single catheter, there were three deaths (20%), two surgical explorations (13.3%), eight emergent pericardiocenthesis (53.3%), and one event of severe anoxic brain damage (6.7%).
Conclusion: The dual catheter technique is a relatively safe and reproducible approach to treat a PCI induced severe coronary artery perforation, and may improve outcome compared to historical series.
