|Six-month clinical follow-up of the Tryton side branch stent for the treatment of bifurcation lesions: a two center registry analysis.|
|PMID: 20824767 Owner: NLM Status: MEDLINE|
|BACKGROUND: Treatment of bifurcation lesions with the Tryton Sidebranch stent has been shown to be feasible with an acceptable clinical outcome and low side branch late loss in the first in man trial.
OBJECTIVE: To report acute procedural and six month clinical follow-up after the use of the Tryton Sidebranch stent in an "all comer" registry.
METHODS: The first 100 coronary bifurcation lesions assigned for treatment with the Tryton stent were included in a prospective registry. Procedural and angiographic success rates were determined from patient charts and pre- and postprocedural quantitative coronary angiography.
RESULTS: Totally, 96 patients with 100 lesions were included in the study. Seventy-two percent presented with stable angina, 25% with unstable angina/NSTEMI, and 3% STEMI. The bifurcation was located in the left main in 8%. Two lesions were chronic total occlusions. Sixty-nine percent were true bifurcation lesions. One failure of stent delivery occurred. Acute gain in SB was 0.76 ± 0.64 mm and three patients had residual stenosis of >30%. Angiographic success rate was 95%; procedural success rate reached 94%. Peri-procedural MI occurred in two and there was one cardiac death during hospitalization. At a median six months follow-up, TLR rate was 4%, MI 3%, and cardiac death 1%. The percentage MACE-free survival at six months was 94%. No cases of definite stent thrombosis occurred.
CONCLUSIONS: In a real world the use of the Tryton Sidebranch stent is associated with good procedural safety and angiographic success rate and acceptable outcome at six months of follow-up.
