ABSTRACT


OBJECTIVES - The aim of this study was to investigate the impact of optimizing procedure-related factors during drug-eluting balloon (DEB) angioplasty on clinical outcomes of drug-eluting stent in-stent restenosis (ISR).


BACKGOURND - Although DEB angioplasty is recommended as a reasonable option for ISR, recurrent target lesion failure (TLF) still occurs in many patients after DEB angioplasty.

METHODES - Consecutive patients with drug-eluting stent ISR treated with DEB (SeQuent Please) were collected from 4 centers in Korea. The primary outcome was 2-year TLF. Procedure-related modifiable independent predictors for TLF and their best cutoff values were determined.

RESULTS - In a total of 256 patients (309 lesions), TLF occurred in 52 patients (20.3%). Modifiable independent predictors of TLF among procedure-related factors were residual diameter stenosis after lesion preparation (residual percentage diameter stenosis [%DS]), DEB-to-stent ratio (BSR), and DEB inflation time (Tinflation), whose best cutoff values were 20%, 0.91, and 60 s, respectively. TLF rates were significantly higher in groups with residual %DS ≥20% (34.7% vs. 12.5%; adjusted hazard ratio: 2.15; 95% confidence interval: 1.86 to 2.48; p < 0.001), BSR ≤0.91 (46.4% vs. 21.9%; adjusted hazard ratio: 2.02; 95% confidence interval: 1.75 to 2.34; p < 0.001), and Tinflation ≤60 s (26.2% vs. 14.0%; adjusted hazard ratio: 1.82; 95% confidence interval: 1.36 to 2.45; p < 0.001). When classifying ISR lesions by combination of procedure-related factors, TLF occurred in 8.3% in the fully optimized procedure group (residual %DS <20%, BSR >0.91, and Tinflation >60 s) and 66.7% in the nonoptimized group (residual %DS ≥20%, BSR ≤0.91, and Tinflation ≤60 s) (p < 0.001).

CONCLUSIONS - Residual %DS after lesion preparation, BSR, and Tinflation were the only modifiable procedure-related factors in DEB angioplasty. Fully optimized DEB angioplasty with optimal lesion preparation, prolonged inflation, and sufficient dilation may play an important role in reducing TLF after DEB angioplasty.
