Full description

A Prospective Multi-center Randomized Trial Assessing the Efficacy and Safety of Active Transfer of Plaque vs. Provisional T Stenting for the Treatment of Non-Left-Main Coronary Bifurcation Lesions.

The purpose of this trial is to evaluate the efficacy and safety of Active Transfer of Plaque and provisional T stenting techniques treating non-left-main coronary bifurcation lesions based on TLR rate 12-months post-procedure.

Provisional T Stenting is a common technique in BL treatment. Active Transfer of Plaque or ATP was reported, but there are no comparison between two procedure. In the ATP treatment of bifurcation lesions, two wires are advanced to distal main vessel (MV) and side branch(SB). Stent and balloon are advanced to MV and SB respectively. The MV stent is released while dilating the SB balloon. By predilating the balloon in the target SB, the plaque will be actively transferred from SB to MV. Subsequently, the plaque will be fixed by the expansive stent in MV.As to the provisional T treatment, provisional T stenting is the typic step-T stenting. In brief, two wires are advanced to distal MV and SB. Predilation is left at operator's discretion, however, predilating SB is not encouraged. Kissing balloon inflation before stenting MV is left at operator's discretion. A stent with stent/artery ratio of 1.1:1 is inflated in MV. Rewire to SB is also left at operator's discretion. FKBI is recommended if there is at least one of following: residual stenosis>75%, >type B dissection and TIMI flow<3.

All patients will be followed clinically at 1-, 6- 12- and 24-month after stent implantation. Repeat angiographic follow-ups are recommended for all patients at 12 months after the index procedure.

The primary endpoint of the trial is the rate of TLR at 12-month follow-up.

Description:

This arm plan to enroll 158 subjects. Sirolimus-eluting Drug stent implantation via Active transfer of Plaque technique in the treatment of non-left-main bifurcation lesion.In the ATP technique treatment of bifurcation lesions, by the balloon pre-dilation in the target side branch, the plaque will be actively transferred from side branch to main vessel. Subsequently, the plaque will be fixed by the expansive stent in main vessel. A stent with stent/artery ratio of 1.1:1 is inflated in MV. Rewire to SB is also left at operator's discretion. FKBI or stent in SB is recommended if there is at least one of following: residual stenosis\>75%, \>type B dissection and TIMI flow\<3.
