Abstract :

ObjetiveS: The aim of this work is to expose a successful hyid management program of CTO lesions, into a high volume interventional cardiology center.

BACKGROUND:

The benefit of successful recanalization of CTO on prognosis remains uncertain.

METHODS:

From January 2015 to March 2016, a retrospective recruitment of 81 patients undergoing PCI for CTO at the Arnault Tzanck Institute, Saint Laurent du Var, France.

RESULTS:

During 1 year follow up, The mean age was 65 +/– 10,5 years with male predominance. The average J–CTO score was 2 +/– 1.2.The antegrade technique has been used as first–line therapy in 97% of patients and we performed retrograde technique in 23%. Procedure success rate was 75.6%. DES implantation rate in recanalized lesions was 100%. The all cause mortality rate was 0%.We have identified four predictors of recanalization failure: The presence of moderate to severe calcification, OR = 0.33 with 95% CI [0.11–0.96], p = 0.05.The occlusion segment length> 20 mm, OR = 0.19 with 95% CI [0.04–0.88], p = 0.034. The J CTO score> 2, OR = 0.21 with 95% CI [0.07–0.63], p = 0.005. Antegrade–retrograde technique switch, OR = 0.2 with 95% CI [0.06–0.66], p = 0.008.

CONCLUSIONS:

CTO program using hyid strategy improves recanalization success rates despite the complexity of the lesions, with a very low intra hospital events rate.
