AB  - OBJECTIVES: This study was to evaluate the longitudinal and radial function of 
      the left- and right-side ventricular septum (Ls and Rs) in patients with acute 
      anterior myocardial infarction (AMI) by tissue Doppler imaging. METHODS: Thirty 
      patients with anterior ST-elevation AMI and revascularization and 20 age-matched 
      normal subjects were enrolled as controls. The longitudinal and radial systolic 
      tissue velocity (TV), strain rate (SR) and strain (varepsilon) of both Ls and Rs were 
      assessed. RESULTS: In normal, there were no significant differences of 
      longitudinal TV, SR and varepsilon between the Ls and Rs. The radial TV was same directed, 
      but larger in Ls than Rs (P < 0.001). The radial SR and varepsilon were positive values of 
      Ls and negative values of Rs, but the degrees were similar in both sides. In AMI, 
      longitudinal and radial TV were significantly decreased in both sides. However, 
      longitudinal and radial SR and varepsilon were significantly decreased in Ls only (P < 
      0.001 in all). Fourteen patients with AMI who showed no functional recovery had 
      more reduced radial varepsilon of Ls (3.9 +/- 1.5% vs. 5.5 +/- 2.1%, P = 0.02), but not 
      longitudinal varepsilon of Ls than the other 16 patients with recovery. CONCLUSION: This 
      study showed the ventricular septum can be functionally differentiated the Ls 
      from the Rs, which can be well demonstrated by SR imaging. The impairment of 
      radial rather than longitudinal function of the Ls was related to no functional 
      recovery.
