| Sumario: | The objective of this study was to noninvasively estimate the left ventricular end diastolic pressure (LVEDP) in healthy dogs, using a modification of the original technique and formula developed by Palomo et al. The values obtained were compared with those obtained using the Doppler technique to calculate the index between E transmitral and tissue E? waves. The modified and used formula was: PDFVI = 21.6 * (q-C / Tf-E) + 1.1. Two hundred and thirty healthy dogs (108 females and 122 males) were studied; the average weight was 14.5 kg, and the average age was 8 years. Following the recommendations validated by the American Society of Echocardiography, a short-axis echotomogram was performed in the right parasternal window at the level of the mitral valve in the guided M-mode format, and simultaneously recording an electrocardiogram. To make the comparison with the investigated method, a pulsed Doppler study of transmitral flow and tissue Doppler imaging was carried out. The proposed procedure was simple, useful, reliable, and reproducible in the daily clinic. Similarity tests were performed between both methods, a linear regression model was developed between the new proposed method (Palomo?s modified formula) and the reference method (Em/Et). In addition, the correspondence techniques (TSI), Pearson?s correlation coefficient, the t test, the r test, and the study of the confidence intervals were applied, not finding significant statistical differences. The results expressed as arithmetic mean ± standard error were for the Em/Et ratio of 9.43 ± 0.037 with a coefficient of variation (CV) of 5.88 % and confidence interval of (CI) 95 % Li 9.36 and Ls 9.51. For the proposed modified formula of 10.027 ± 0.34 with CV 4.83 % and 95 % CI Li 9.97 and Ls 10.10. |
