Right Atrial Deformation Using Cardiovascular Magnetic Resonance Myocardial Feature Tracking Compared with Two-Dimensional Speckle Tracking Echocardiography in Healthy Volunteers.

摘要: Speckle tracking echocardiography (STE), and more recently, cardiovascular magnetic resonance myocardial feature (CMR-FT) provides insight into all phases of atrial function. The aim our study was to compare RA strain using CMR-FT STE also assess the relationship between LA strain. A total 61 healthy volunteers with mean age 45 ± 13 years had adequate for analysis on 2D-STE. Females larger reservoir (39 ± 15% vs. 32 ± 13%, p = 0.046) conduit (26 ± 12% 20 ± 9%, p = 0.03) when compared males, but not case booster (14 ± 7% 12 ± 6%, p = 0.45). In comparison derived strain, were significantly different three gating methods (p > 0.05 all). Noticeably, there no significant differences in rate function fair good intra- inter-observer reproducibility superior
