Key result
Stenting of long and complex tapered coronary artery lesions poses challenges during percutaneous coronary intervention and is associated with higher risks of stent thrombosis and restenosis.
Why the study?
Tapered coronary artery lesions may pose particular challenges during PCI and impact procedural and clinical outcomes.
May warrant technique optimization in tapered-lesion PCI; leaves open dedicated-device trials.
The success of a PCI is best defined by three related components: post-procedure angiographic outcomes, procedural events, and longer-term clinical outcomes. Stenting of long and complex lesions is associated with higher risk of stent thrombosis and restenosis even at long term follow-up. Tapered lesions (i.e., a significant mismatch between proximal and distal reference lumen diameters (RLD)) of the target coronary artery lesion may pose particular challenges during PCI and impact outcomes.

Vashee et al. (2022) conducted a review in Tapered Coronary Artery Lesions. Percutaneous coronary intervention was evaluated. Stenting of long and complex tapered coronary artery lesions poses challenges during percutaneous coronary intervention and is associated with higher risks of stent thrombosis and restenosis.
