Comparison of two- and three-dimensional quantitative coronary angiography to intravascular ultrasound in the assessment of intermediate left main stenosis
The American Journal of Cardiology, 05/31/2012
Porto I et al. – The accuracy of quantitative coronary angiography in predicting LM intravascular ultrasound (IVUS) minimum luminal area <6 mm2 is limited. When IVUS is not available or contraindicated, 3D quantitative coronary angiography may assist in the evaluation of intermediate LMS. Among 2D–QCA parameters, minimum luminal diameter is more accurate than percent diameter stenosis in predicting significant LMS.
