Article Synopsis
- Stent underexpansion, a condition linked to calcified lesions, can also happen in non-severely calcified lesions and is a key predictor of complications after cardiac procedures.
- In a study of 993 patients, it was found that 3.6% of non-severely calcified lesions experienced underexpansion, and these cases showed greater calcium arc and thickness compared to those without underexpansion.
- Factors like larger and thicker eccentric calcium in the mid left anterior descending artery and negative remodeling were identified as potential contributors to underexpansion, which may lead to higher two-year target lesion failure rates.
Background: Whether an eruptive or noneruptive target lesion calcified nodule (CN) portends worse acute and long-term clinical outcomes after stenting has not been established.
Objectives: The authors sought to compare acute and long-term clinical outcomes in eruptive CN vs noneruptive CN morphology.
Methods: Using optical coherence tomography, an eruptive CN was defined as an accumulation of small calcium fragments protruding and disrupting the overlying fibrous cap, typically with small amount of thrombus.
