“…The contribution of atrial contraction (a‐wave) was defined as described by Hammarström (Hammarström et al ., 1991). The ventricular systolic wave (syst‐wave) was measured from 60 ms after the beginning of the QRS complex to the first peak on the systolic wave, which corresponds to mitral and aortic valve closure, respectively, in order to reflect ventricular systole in an optimal way (Carlhäll et al ., 1999). The ratio between a‐wave and syst‐wave was calculated to reflect ventricular diastolic function (Blomstrand et al ., 1996).…”

In the subjects studied, with a range of normal cardiac dimensions, AVPD correlated to stroke volume, end-diastolic volume and maximal oxygen consumption per body weight, but not to EF. On theoretical grounds, it also seems reasonable that a dimension like AVPD is related to other cardiac dimensions and volumes, rather than to a fraction, like EF. AVPD is one parameter that is useful for evaluation of left ventricular systolic function but is not interchangeable with other measurements such as EF.

“…Measurements were performed 60 ms after the beginning of QRS to the peak displacement of the tricuspid annulus towards the apex in systole. 13 For the acquisition of tissue Doppler velocities of the tricuspid annulus, data were collected in accordance with the recommendations for the quantification of Doppler echocardiography. 14 Peak systolic velocity was measured avoiding the initial peak observed during isovolumic contraction time ( Figure 1C).…”

“…When applied to healthy subjects, we obtained significant differences of importance in comparison with conventional methodology (Carlhäll et al, 1999). However, clinical work has shown that this traditional method, based on the outline of the annulus motion curve, does not reflect true systole in an optimal way.…”

Analysis of atrioventricular plane displacement (AVPD) is a well established method for assessment of both systolic and diastolic ventricular function. For several years, AVPD has been a clinical tool and there are many current, as well as potential, areas of application. However, clinical work has shown that the traditional method for evaluation of systolic ventricular function, called total AVPD, does not temporally reflect true systole. Systolic AVPD is a new approach for measuring AVPD to assess ventricular systolic function. We wished to apply this new model in healthy subjects and in patients with different common heart diseases. Twenty-eight young healthy males and 30 patients (aortic stenosis, left sided regurgitant lesions, postmyocardial infarction) were enrolled. AVPD was obtained at the four standard sites by M-mode. Total AVPD was measured in the conventional way and systolic AVPD by identifying true systole, by means of mitral- and aortic valve closure respectively. Ventricular volumes were calculated according to biplane Simpson's rule. The systolic AVPD measurements were significantly lower than the total measurements, at both atrioventricular planes in all groups (P<0.001). This discrepancy was greater at the mitral than at the tricuspid annulus in the patients 24.2% vs. 15.5% (P<0.001), but did not differ in the healthy subjects. At the mitral annulus, this discrepancy also seemed to be more pronounced in the patients than in the healthy subjects 24.2% vs. 10.7%. When assessing ventricular systolic function by AVPD, the conventional method overestimates the amplitude in relation to true systolic function in both patients with heart disease and in young healthy males. Thus, there are uncertainties regarding earlier estimations of AVPD in terms of expression of systolic function and regarding previously presented reference values. We recommend the proposed methodology.
