{Abstract}: BACKGROUND: Drug-coated balloon (DCB) angioplasty seems a safe and effective option for specific de novo coronary lesions. However, the beneficial effect of intravascular ultrasound (IVUS)-guided DCB angioplasty in de novo lesions remains uncertain.
OBJECTIVE: This study aimed to assess the benefits of IVUS guidance over angiography guidance during DCB angioplasty in de novo coronary lesions.
METHODS: A total of 260 patients with high bleeding risk who had a de novo coronary lesion (reference vessel diameter 2.0-4.0 mm, and lesion length ≤15 mm) were randomly assigned to either an IVUS-guided or an angioplasty-guided DCB angioplasty group. The primary endpoint was in-segment late lumen loss (LLL) at 7 months after procedure. The secondary endpoint was target vessel failure at 6 months.
RESULTS: A total of 2 patients in the angiography-guided group and 7 patients in the IVUS-guided group underwent bailout stent implantation (P = 0.172). The primary endpoint of 7-month LLL was 0.03 ± 0.52 mm with angiography guidance vs -0.10 ± 0.34 mm with IVUS guidance (mean difference 0.14 mm; 95% CI: 0.02-0.26; P = 0.025). IVUS guidance was also associated with a larger 7-month minimal lumen diameter (2.06 ± 0.62 mm vs 1.75 ± 0.63 mm; P < 0.001) and a smaller diameter stenosis (28.15% ± 13.88% vs 35.83% ± 17.69%; P = 0.001) compared with angiography guidance. Five target vessel failures occurred at 6 months, with 4 (3.1%) in the angiography-guided group and 1 (0.8%) in the IVUS-guided group (P = 0.370).
CONCLUSIONS: This study demonstrated that IVUS-guided DCB angioplasty is associated with a lower LLL in patients with a de novo coronary lesion compared with angiography guidance. (Intravascular Ultrasound Versus Angiography Guided Drug-Coated Balloon [ULTIMATE-III]; NCT04255043).
