Optical coherence tomography predictors of target vessel myocardial infarction after provisional stenting in patients with coronary bifurcation disease

BACKGROUND Provisional side branch (SB) stenting is correlated with target vessel myocardial infarction (TVMI) in patients with coronary bifurcation lesions. However, the mechanisms underlying this association remain unknown. OBJECTIVES To determine the correlation between SB lesion length with vulnerable plaques and TVMI using optical coherence tomography (OCT). BACKGROUND The correlation between SB lesion length with vulnerable plaques and TVMI is unknown. METHODS A total of 405 patients with 405 bifurcation lesions who underwent preprocedure OCT imaging of both the main vessel (MV) and the SB were enrolled. Patients were divided into long SB lesion (SB lesion length ≥10 mm) and short SB lesion (SB lesion length
