Unrecognized stenosis by angiography documented by intravascular ultrasound imaging
1Division of Cardiology, University of California, Irvine Medical Center, Orange 92668.
Abstract:
This report documents how intravascular ultrasound imaging was used to diagnose a short "napkin-ring" stenosis that was missed by coronary angiography. Intravascular ultrasound revealed a lumen of 2.6 x 2.5 mm in diameter and 5.0 mm2 in cross-sectional area, with a residual atheroma that occluded 63% of available cross-sectional area at the stenosis.
