Baseline V-RESOLVE Score Guided Versus Angiography Guided Stent Implantation in Coronary Bifurcation Lesions (CIT-RESOLVE II)

"Jailed wire technique (JWT): Both main vessel (MV) and side branch (SB) are wired. The MV is stented with wire protection in SB. If suboptimal results exist, the SB would be rewired and a kissing balloon inflation (KBI) is undertaken.~Jailed balloon technique: A monorail balloon is advanced into the SB. If there is TIMI flow grade decrease in the SB after MV stenting, the SB balloon is inflated to simulate attempt to reopen the SB.~Provisional two-stent strategy: Lesion preparation and MV stenting are consistent with JWT. Provisional SB stenting could be undertaken when suboptimal results occur after SB rewiring and a KBI is undertaken.~Elective two-stent strategy: Patients in this subgroup would undergo crush procedure or any other elective two-stent strategy which usually stenting SB before MV stenting."

The choice of interventional strategy was left to the discretion of experienced interventionists based on the coronary angiogram.
