Incidence and Predictive Factors of Chronic Vessel Enlargement After Percutaneous Coronary Intervention for Severely Stenotic and Occluded Lesions

摘要

Background: Chronic vessel enlargement (CVE) of the coronary artery is observed in patients who undergo percutaneous coronary intervention (PCI) for severely stenotic or occluded lesions. Recently, the presence of a peri-medial high-echoic band (PHB) identified by intravascular ultrasound (IVUS) has been reported to correlate with this phenomenon. We sought to assess the incidence, predictive factors of CVE, and association between CVE and PHB.
