AIM: 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 1 496 coronary angiograms were performed. The indication was ischemic heart disease in 1 197 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 1 197 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.
