Feasibility of transradial approach in a hub and spoke cath lab network.
OBJECTIVE
Radial artery approach for coronary angiography presents advantages in terms of reduction of costs and complications. Opening a diagnostic-only cath lab is controversial in an era of interventional approach. The authors present the data of Carpi diagnostic-only cath lab (Spoke), satellite of the main cath lab situated in Modena (Hub) 20 Kms apart.


METHODS
Between January 2004 and December 2007, 1496 coronary angiograms were performed. The indication was ischemic heart disease in 1197 cases (80%), dilated cardiomiopathy in other 165 cases (11%) and valvular heart disease in the remaining 134 patients (9%). The procedure was performed percutaneously via radial artery in 95% (N=1421) of the cases, via brachial artery in 1% (N=15) and via femoral artery in the remaining 4% (N=60) of patients.


RESULTS
Among the 1197 patients undergoing coronary angiography for ischemic heart disease, an indication to medical therapy was given in 443 (37%), a surgical indication in 216 (18%) patients and an indication to percutaneous coronary intervention (PCI) in 538 (45%) cases. PCI was performed in the Hub centre the same day and via the same arterial approach of the diagnostic angiography, maintaining the sheath in situ during transport. In 6 patients only it was necessary to shift to a femoral approach.


CONCLUSIONS
This model presents many advantages: 1) a cath lab in a peripheral hospital allows a early carrying out of the hemodynamic examination with reduction of hospital stay; 2) transport to the Hub centre cath lab is undertaken only in patients who really need PCI; 3) the PCI is feasible the same day of the diagnostic examination; 4) this model relieves the hub centre congestion, ensuring motivation and professional competence for personnel of peripheral hospital.
