Long-term clinical and angiographic outcomes of the sleeve technique on non-left-main coronary bifurcation lesions.
OBJECTIVE
The purpose of this study was to examine the long-term results of the sleeve technique, which is a modification of the crush technique and capable of increasing the success of final kissing balloon inflation (FKB) in the treatment of non-left-main coronary bifurcation lesions.


RESULTS
Forty-five patients with 45 non-left-main coronary bifurcation stenoses were treated with drug-eluting stents (DES) using the sleeve technique and prospectively evaluated. Follow-up angiography was performed on 41 patients (91%) at nine months. The mean age of patient was 65 years with predominance of male (73%); FKB was successfully performed in all patients. Post-procedure myocardial infarction was observed in four patients, leading to an in-hospital major adverse cardiac event (MACE) rate of 9%. At angiographic follow-up, the late loss in the main vessel and side-branch was 0.18+/-0.26 mm and 0.29+/-0.27 mm, respectively. Binary angiographic restenosis was seen in two patients (4.7%) at main vessel and one patient (2.4%) at side-branch. At 1-year follow-up, there were two non-cardiac deaths and three patients needed revascularisation.


CONCLUSIONS
The use of the sleeve technique and DES in the treatment of non-left-main coronary bifurcation lesions is associated with a low angiographic restenosis, particularly at side branch ostium, and long-term safety.
