Clinical Research Impact of Interventional Strategy for Unprotected Left Main Coronary Artery Percutaneous Coronary Intervention on Long-term Survival

Le résumé fourni par la source

Background: Percutaneous coronary intervention (PCI) of unprotected left main coronary artery (ULMCA) is feasible. In cases involving the left anterior descending‐left circumflex bifurcation, the optimal interventional strategy remains unclear. Randomized bifurcation trials in the past excluded ULMCA lesions. Methods: A single-centre registry study with retrospective analysis of the interventional protocols and procedural angiograms of 102 patients who underwent stent PCI of ULMCA was performed in order to evaluate the impact of the interventional strategy on long-term survival. Results: Isolated stenting of the ostium or mid ULMCA without bifurcation stenting was performed in 19 patients. Most interventions (n 83) involved the left main bifurcation. Distal or bifurcation lesions were treated by provisional T-stenting in cases of single involved ostium (left anterior descending or right circumflex) or systematic T-stenting or V-stenting if both proximal coronary arteries were involved (n 19).
