What this trial studies

The CTO-DENOVO study is a multicenter registry that focuses on patients with new chronic total occlusions (CTO) of the coronary arteries who are treated using a drug-coated balloon (DCB) strategy. The study aims to evaluate the effectiveness of this approach by measuring target lesion failure at 6 months, along with late lumen loss and minimal lumen area through follow-up imaging. This observational study will gather data from multiple centers to assess outcomes and improve treatment strategies for coronary artery disease.

Who should consider this trial

Good fit: Ideal candidates are patients with de novo coronary CTO who can undergo successful recanalization using a DCB-only strategy.

Not a fit: Patients with in-stent CTO or those treated with drug-eluting stents (DES) will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the effectiveness of treatments for patients with chronic total occlusions in coronary arteries.

How similar studies have performed: While there have been studies on drug-coated balloons, this specific approach to treating de novo CTOs is relatively novel and not extensively tested.
