Despite recent recommendations for the use of drug‐coated balloon (DCB) in this lesion, there are concerns about crossover‐stenting from the left main trunk (LMT) to the left anterior descending artery (LAD). Specifically, isolated DCB treatment for the ostial LCx lesion may induce carina shift, while conventional kissing balloon technique (C‐KBT) with a standard balloon and a DCB may prolong LMT occlusion, leading to hemodynamic instability. Objectives This study aimed to evaluate the safety and feasibility of a novel double‐effect KBT (W‐KBT) using a perfusion balloon (PB) for the LMT‐LAD and a DCB for the LMT‐LCx, allowing prolonged inflation while maintaining coronary perfusion. Methods This single‐center prospective study enrolled consecutive patients with de‐novo LMD and ostial LCx lesions, requiring crossover‐stenting from the LMT to the LAD followed by proximal optimization technique and C‐KBT. After confirming optimal PCI, W‐KBT was performed. Results Among 12 enrolled patients (mean age 73.8 ± 7.2, 91.7% men), procedural success, defined as device delivery and W‐KBT time ≥ 30 s, was achieved in all cases via the transradial approach. W‐KBT inflation‐time was consistently 60 s; ST changes occurred in 50% (no ST‐elevation); mean ST‐change time was 41.2 ± 7.1 s; mean delta‐blood pressure was −13.7 ± 11.4 mmHg; mean delta‐heart rate was −3.4 ± 5.9 bpm; and no inotropes or mechanical cardiac support were needed. Conclusion Within the limited sample size of this pilot study, the safety and feasibility of the first‐in‐man W‐KBT were suggested. Summary This pilot study evaluated the safety and feasibility of a novel double‐effect kissing balloon technique (W‐KBT) in percutaneous coronary intervention for left main coronary artery disease, realized by the combined use of a perfusion balloon and a drug‐coated balloon. Among 12 patients, device delivery was successful via a transradial approach using a 7 Fr guiding catheter. The W‐KBT was maintained for 60 s without hemodynamic instability, providing adequate drug application to the ostial left circumflex artery lesion. Furthermore, no ST‐elevation or periprocedural myocardial infarction was observed, highlighting the safety and feasibility of this technique. 10.1002/ccd.31621 http://creativecommons.org/licenses/by-nc/4.0/ |
