Distribution of Dyssynchrony in Subjects with No Known Cardiac Disease and Comparison of Velocity Vector Imaging to Color-Coded Tissue Doppler Imaging.
Data on the distribution of dyssynchrony in subjects with normal ejection fraction ( EF) and normal QRS are scarce. We studied 100 subjects with no known cardiac disease (52% male, mean age 60 ± 17 years) using velocity vector imaging ( VVI). Seventeen percent had septal to lateral ( S- L) wall long...

We studied 100 subjects with no known cardiac disease (52% male, mean age 60 ± 17 years) using velocity vector imaging ( VVI). Seventeen percent had septal to lateral ( S- L) wall longitudinal delay >75 msec, 63% of subjects had S- L wall radial delay >75 msec, and 25% had a circumferential opposing wall delay >100 msec. Those with circumferential opposing wall delay of >100 msec had a lower EF (57 ± 5% vs. 62 ± 5%, P < 0.05). In an additional group of 33 patients, we compared the longitudinal dyssynchrony parameters as assessed by VVI and tissue Doppler imaging ( TDI) and found them to be comparable. In conclusion, we find significant variation in time to peak velocities in subjects with no known cardiac disease, who had a normal left ventricular ejection fraction and QRS duration. VVI is comparable to TDI. pubtype: Academic Journal doctype: diagnostic images research tables/charts tracings Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
