Three years of experience with a mobile angiograph in a center without on-site surgical back-up.
BACKGROUND
The safety of percutaneous coronary interventions (PCI) performed in centers without surgical back-up is controversial, but data from several western countries indicates that this approach can be extended to a larger number of hospitals. We assessed the safety and efficacy of performing angiography and PCI with a mobile C-arm angiograph in a center without on-site surgical back-up, and compared our data with that reported in the literature.


METHODS
We retrospectively analyzed 1485 coronary angiograms and 172 PCI procedures performed in our center from January 2001 to May 2003 using a mobile angiograph. Half of the patients that have undergone PCI had refractory unstable angina and one-third had acute myocardial infarction (AMI). The safety of PCI was assessed by the analysis of in-hospital complications (death, urgent need for repeated revascularization, AMI with or without ST elevation and stroke). The PCI procedures were considered effective when the post-PCI residual stenosis did not exceed 50% with distal Thrombolysis in Myocardial Infarction (TIMI) grade 3 flow.


RESULTS
In patients who underwent diagnostic coronary angiography there were no deaths, anaphylatic shock, acute renal failure or major ischemic complications. In patients who underwent PCI, the mortality rate was 1.1% (2 deaths), two patients (1.1%) developed acute MI with ST segment elevation, one patient (0.5%) underwent repeated PCI and three patients (1.7%) were referred for urgent by-pass surgery.


CONCLUSIONS
Diagnostic and PCI procedures can be safely performed using a mobile angiograph. The efficacy and safety requirements of PCI, performed in a center without an on-site surgical back-up facility using a mobile angiograph were similar to other data reported in the literature.
