Comparing two stent techniques for treating coronary artery bifurcation lesions

The COMPLETE Treatment of Bifurcation With Two-stent Techniques: Randomized Comparison of Crush Versus Culotte Technique

Not applicable Interventional Yonsei University · NCT05488665

This study is testing which of two stenting techniques works better for people with certain types of heart artery blockages to see which one helps them more after a year.

What this trial studies

This trial aims to compare the effectiveness of two stenting techniques, the crush technique and the culotte technique, for treating bifurcation lesions in patients with coronary artery disease. Using contemporary second-generation drug-eluting stents, the study will evaluate which technique leads to better outcomes in terms of target-lesion failure after one year. Eligible participants will be those with specific types of bifurcation lesions that can be treated with two stents. The study is randomized to ensure unbiased results.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 and older with specific de novo bifurcation lesions suitable for drug-eluting stent implantation.

Not a fit: Patients who are pregnant, unable to commit to follow-up, or experiencing acute myocardial infarction or cardiogenic shock may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the most effective stenting technique for patients with bifurcation lesions, potentially improving their long-term outcomes.

How similar studies have performed: Previous studies have explored various stenting techniques for bifurcation lesions, but this specific comparison of crush versus culotte techniques is relatively novel.
