Dual catheter technique for the treatment of severe coronary artery perforations.
OBJECTIVE
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%).


CONCLUSIONS
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.
