Treatment of Coronary Bifurcation Lesions: Current Knowledge and Future Perspectives

Coronary lesions at bifurcation sites are frequent and still remain a challenging subset for the interventional cardiologist. Although in the last years the provisional stenting technique has shown more consistent results, coronary bifurcation interventions still share a worse procedural success rate and increased rates of mid- and long-term cardiac events. Most of the dedicated devices proposed in the last few years have failed to show improved results when compared with standard devices. The broader use of imaging techniques, such as intravascular ultrasound and optical coherence tomography, lead to a better understanding of the real anatomy of bifurcations and has shown to be a great tool for percutaneous coronary intervention optimization. Preliminary results come from drug-coated balloons and bioresorbable vascular scaffolds, especially for the 'leave nothing behind' concept, particularly interesting in this setting of lesions.
