Summary: | Objectives
This study sought to compare the efficacy and clinical safety of the LONGTY drug‐coated balloon (DCB) with those of SeQuent Please DCB in patients with in‐stent restenosis (ISR).
Background
Although DCB technologies have evolved, little is known about the clinical efficacy of the new‐generation LONGTY DCB.
Methods
This was a prospective, multicenter, randomized, noninferiority trial comparing LONGTY DCB with SeQuent Please DCB in patients with ISR. The primary endpoint was target lesion late lumen loss at 9 months' follow‐up.
Results
A total of 211 patients with ISR from 13 Chinese sites were included (LONGTY DCB, n = 105; SeQuent Please DCB, n = 106). Device success was achieved in all patients. At the 9 month angiographic follow‐up, target lesion late lumen loss was 0.35 ± 0.42 mm with LONGTY and 0.38 ± 0.45 mm with SeQuent Please (p for noninferiority <.001). The target lesion revascularization rates at 1 year were similar in both DCB groups (15.24 vs. 13.21%; p = .673). Over an extended follow‐up of 2 years, the clinical endpoints, including cardiac death, myocardial infarction, and thrombus rate, were extremely low and similar in both groups.
Conclusions
In this multicenter, head‐to‐head, randomized trial, the new‐generation LONGTY DCB was noninferior to the SeQuent Please DCB for the primary endpoint of target lesion late lumen loss at 9 months. |
