title: Estimation of left ventricular end-diastolic pressure by color M-mode Doppler echocardiography and tissue Doppler imaging.
abstract: OBJECTIVE
  The aim of this study was to estimate left ventricular end-diastolic pressure (LVEDP) noninvasively by tissue Doppler imaging and color M-mode echocardiography.
  
  
  METHODS
  We studied 3 groups of patients who were proven by angiography to be free of significant coronary artery lesions (<40% stenosis) with an LVEDP < 10 mm Hg (group A: n = 24; 16 men, 18 women; mean age +/- SD = 55 +/- 13 years), an LVEDP of 10 to 15 mm Hg (group B: n = 21; 17 men, 4 women; mean age 56 +/- 11 years), or an LVEDP > 15 mm Hg (group C: n = 35; 20 men, 15 women; mean age 58 +/- 9 years). Tissue Doppler imaging of the lateral mitral annulus and color M-mode imaging of the mitral valve in the apical 4-chamber view were obtained with an echocardiographic system. Early and late diastolic velocities (Em and Am, respectively), Em deceleration time (EmDT), Am time (Am-t), and mitral propagation velocity time delay (VpDT) were measured in each patient.
  
  
  RESULTS
  In group A, sensitivity and specificity for EmDT < or = 100 ms, Am-t < or = 90 ms, Em/Am > or = 1, and VpDT < or = 45 ms were found to be 0.57 and 0.89, 0.66 and 0.88, 0.86 and 0.92, and 0.73 and 0.89, respectively. In group B, sensitivity and specificity for EmDT 100 to 120 ms, Am-t 90 to 110 ms, Em/Am 1 to 0.5, and VpDT 45 to 60 ms were found to be 0.57 and 0.84, 0.69 and 0.82, 0.66 and 0.75, and 0.55 and 0.83, respectively. In group C, sensitivity and specificity for EmDT > 120 ms, Am-t > 110 ms, Em/Am < 0.5, and VpDT > 60 ms were found to be 0.88 and 0.81, 0.71 and 0.80, 0.86 and 0.72, and 0.78 and 0.86, respectively.
  
  
  CONCLUSIONS
  The EmDT, Am-t, Em/Am, and VpDT measurements obtained noninvasively by left ventricular tissue Doppler imaging and mitral flow propagation velocity were found to be useful in the estimation of LVEDP.
