    Guiding Light: Insights Into Atherectomy by Optical Coherence Tomography

    Coronary calcification presents multiple technical challenges in percutaneous coronary intervention (PCI) and is associated with suboptimal procedural results and an increase in subsequent adverse clinical events (1) . Currently, there is no standardized evidence-based strategy for PCI of calcified coronary lesions. Decisions for the use of adjunctive atheroablation—shown to increase the acute procedural success rates (2) —are based on visual estimation of calcification severity on angiography (with its inherent limitations [3] ) or when delivery of devices is impeded by calcified deposits in the vessel wall. Although the so-called “rota-regret” remains common following suboptimal acute procedural results in calcified plaques not ...
