Abstract

Background: Percutaneous coronary intervention (PCI) for complex bifurcation lesions requiring the use of two stents remains a challenge for interventional cardiologists due to the low success rate and suboptimal outcomes. Current two-stent intervention techniques have limitations, such as multiple layers of stent overlap at the bifurcation site or incomplete coverage of the side branch ostium due to incorrect placement. We describe an improved stenting technique based on the T-stenting method – the Szabo T-stenting technique – which combines T-stenting with the Szabo technique to accurately place the side branch stent at the entrance of the side branch, ensuring complete coverage of the side branch ostium while minimizing stent overlap at the carina and the main vessel. Case report: We present two clinical cases involving two male patients, aged 70 and 71. Both patients had bifurcation lesions in the left main coronary artery and were treated with the Szabo T-stenting technique for the deployment of two coronary stents. The technical success was achieved without any major cardiovascular events during the 30-day follow-up period. Conclusion: PCI for bifurcation lesions remains challenging, and an optimal two-stent technique requires a balance between full lesion coverage and minimal stent overlap at the carina and main vessel. The Szabo T-stenting technique appears to be a feasible and safe two-stent strategy for complex coronary artery bifurcation lesions
