Abstract:
Objective To evaluate the active jailed balloon technique (A-JBT) and conventional jailed balloon technique (C-JBT) in non-left main true coronary bifurcation lesion (CBL) using quantitative flow ratio (QFR).
Methods A total of 255 patients with CBL confirmed by coronary angiography (CAG) were consecutively enrolled from Zhongshan Hospital, Fudan University between May 2019 and May 2020. The clinical characteristics, percutaneous coronary intervention (PCI) related data, immediate events after main vessel stenting as well as QFR of main vessel and side branch were compared between A-JBT group (n=171) and C-JBT group (n=84).
Results There were 261 CBLs included and 204 (78.2%) lesions involved left anterior descending coronary artery (LAD), 232 (88.9%) lesions were Medina 1.1.1. The was no significant difference in procedural details involving target lesion characteristics as well as the stenosis degrees of main vessel and side branch between two groups. After main vessel-stenting, the incidence of acute side branch occlusion in A-JBT group was significantly lower than that in C-JBT group (0.6% vs 10.7%, P < 0.001). Meanwhile, the patients in A-JBT group obtained significantly higher rate of thrombolysis in myocardial infarction (TIMI) grade 3 (96.0% vs 78.6%, P < 0.001), and had higher QFR of side branch (0.900.84, 0.95 vs 0.830.68, 0.91, P < 0.001) compared with C-JBT group.
Conclusion In non-left main true CBL, A-JBT can reduce the incidence of acute occlusion in side branch and improve functional blood supply compared with C-JBT.
