Transradial Szabo technique for intervention of ostial lesions.
OBJECTIVE
The aim of our study is to assess the feasibility and safety of transradial intervention (TRI) of coronary ostial lesions using the Szabo technique.


BACKGROUND
When performing TRI of coronary ostial lesions, precise stent positioning is of paramount importance. TRI has experienced increasing popularity in the U.S.; however, utilization of the Szabo technique has not been systematically evaluated in this setting. We report the results of ostial stent deployment using the Szabo technique for 2 experienced TRI operators and centers.


METHODS
This was a retrospective analysis of 40 consecutive patients who underwent PCI from April 2009 to September 2011. All patients who underwent PCI via the transradial route with the Szabo technique for ostial lesions performed by experienced transradial operators (>200 cases/yr) were included.


RESULTS
In our study of 40 patients with 41 coronary ostial lesions, overall procedural success rate was 100%. Stent dislodgement was seen in 1 patient. Clinical follow up was 100%, with a mean duration of 292.7±200 days. Target lesion revascularization (TLR) was seen in 2 patients (5%). One patient had an episode of transient ischemic attack (TIA) at 33 days after PCI; another experienced subacute stent thrombosis at 81 days while on dual antiplatelet therapy. MACE was 7.5% overall.


CONCLUSIONS
In our study, treatment of coronary ostial lesions with the Szabo technique via TRI is associated with a high procedural success rate and a low MACE of 7.5%.
