While “on-line”<unk>  angiographic is somewhat cumbersome to use in the catheterization laboratory, “off-line”<unk>  angiography has proven invaluable for research investigation in determining the effect of new drugs and devices on lumen dimensions early and late after percutaneous coronary interventions.  Notably, for clinical decision making in intermediate lesions, neither trained visual estimates or on-line<unk>  angiography are substitutes for precise physiologic measurements of stenosis severity, such as fractional flow reserve or coronary Doppler measurements.
