Double Kissing (DK) vs Culotte Technique for Coronary Bifurcation Lesions Lower Silesia Culotte Bifurcation Registry (LSCBR)

What this Trial Is About

Researchers are analyzing outcomes from patients who underwent percutaneous coronary intervention (PCI) for coronary artery disease involving bifurcation lesions. The study compares two different two-stent techniques: the Culotte technique and the Double Kiss (DK) Culotte technique. This retrospective study uses data collected from two high-volume cardiac centers in the Lower Silesia Region between April 2012 and January 2024. The choice of which stent technique to use was made by the treating physician based on clinical and angiographic factors, with no restrictions on lesion characteristics. Patients included had bifurcation lesions treated with either the classical Culotte technique or the DK-Culotte technique, which involves an additional balloon dilation step after side branch stenting. The study groups consist of patients treated with one of these two stenting methods. The PCI was performed following standard clinical indications, with all patients informed about treatment options and risks before consenting. Patients who had previous stenting of the same bifurcation lesion before the procedure were excluded. Participants' outcomes are monitored retrospectively over a 5-year period following their initial hospital stay. The primary outcome measured is target lesion failure, with evaluations every 6 months after hospital discharge. Secondary outcomes include major adverse cardiac events (MACE). This long-term follow-up allows researchers to assess the safety and effectiveness of the two-stent techniques over time using clinical records and data analysis.
