Target vessel-specific efficacy and short-term outcomes of rotational atherectomy in the treatment of chronic total occlusion.

ABSTRACT:

Aim

To compare the procedural features, treatment efficacy, and short-term outcomes of RA for CTO in different target vessels-LAD, LCX, and RCA-and to assess the anatomical compatibility and clinical benefit of RA.

Methods

This retrospective study included 119 patients with single-vessel CTO who underwent RA-assisted PCI from January 2019 to December 2024. Patients were divided into LAD (n = 55), LCX (n = 14), and RCA (n = 50) groups. Clinical characteristics, procedural details, and 6-month MACCEs were compared. Kaplan-Meier and Cox regression analyses were used to assess outcomes and predictors.

Results

RCA-CTO patients were older and had more triple-vessel disease, but showed the lowest MACCEs rate at 6 months (10.0%) compared with LAD (23.6%)
