Abstract:
Objective To evaluate the feasibility and the value of video density scale (VDS) for assessing myocardial microperfusion.MethodsVDS and corrected TIMI frame counted (CTFC) were calculated and compared in 58 cases undergoing coronary catheter angiography.ResultsVDS of 58 cases was (22.5±5.8)and 95% confidence interval of normal myocardial microperfusion is(20.2,24.7).The CTFC was (21.1±4.5).It showed negative correlation between VDS and CTFC.ConclusionVDS is feasible to assess myocardial microperfusion quantificationally.The possibility of myocardial microperfusion dysfunction would be increased when VDS is lower than 20.
