Abstract
<p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:12px">Background: The role of routine angiographic reassessment after percutaneous coronary intervention (PCI) remains debated, particularly in the context of drug-coated balloon (DCB) angioplasty. This study evaluates whether planned angiographic follow-up provides meaningful clinical or procedural benefit after successful DCB treatment.</span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:12px">Methods: Consecutive patients treated with DCB between May 2021 and May 2025 were included. Demographic, procedural and angiographic data were analysed. De decision for angiographic reassessment was scheduled on operator basis. These patients were compared at follow up to identified clinically relevant findings or changed management.</span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:12px">Results: A total of 150 patients were included, of whom 16 (10.7%) underwent planned angiographic reassessment and 134 (89.3%) did not. The mean time to angiographic reassessment was 82 days. Baseline demographic characteristics were similar between groups (mean age 67.25 ± 10.32 vs. 63.69 ± 9.76 years, p = 0.229, predominantly men (p=0.841). Cardiovascular risk burden was high with no significant differences between the two groups for hypertension, dyslipidemia, diabetes mellitus, or previous coronary disease. Clinical presentation (STEMI, NSTEMI, unstable angina, CCS) at admission was similar between groups (p=0.126). The proportion of intra-stent restenosis versus <em>de novo</em> lesions was comparable (p = 0.259). The prevalence of chronic total occlusions (CTO) was significantly higher in the planned angiographic follow-up group compared with the no-follow-up group (37.5% vs. 1.5%, <em>p</em> < 0.001). There were no significant differences in DEB diameter (2.69 ± 0.56 vs. 2.59 ± 0.39 mm, p = 0.867), DEB length (18.42 ± 4.9 vs. 21.25 ± 5.3 mm, p = 0.368) or inflation time (69.9 ± 21.8 vs. 64.7 ± 13.1 seconds, p = 0.433). All control angiographies showed preserved angiographic results, with no need for additional optimisation or further therapeutic intervention. Findings were consistent across subgroups, including non-small-vessel, ISR and bifurcation subgroups.</span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:12px">Conclusion: In this real-world cohort, DCB-treated lesions showed durable angiographic stability and extremely low rates of clinically driven repeat procedures. The absence of actionable findings in all patients undergoing scheduled angiographic reassessment strongly suggests that routine planned angiographic surveillance after successful DCB-PCI could be unnecessary. A follow-up strategy driven by symptoms or clinical change appears safe and appropriate.</span></span></p>
