Effect of Mitral Annulus Motions (Mam) velocity on Pulmonary Venous Flow by Pulsed Tissue and Pulse Doppler Echocardiography in patients with Dilated and Hypertrophied heart.
Pak Armed Forces Med J Jan ;50(1):32-7.

The relationship between mitral annulus motion and pulmonary venous flow velocity pattern has been reported in several heart disease by 2DE, M-mode and pulsed Doppler Echo. Since tissue Doppler imaging (TDI) is a comparatively new technique to detect the low wall motion velocities. The aim of this study was to investigate the correlations between pulsed Doppler derived pulmonary venous and mitral flow velocity variables and TDI-derived mitral annulus motion velocity in patients with dilated and hypertrophied hearts. For this purpose we studied 10 patients with DCM, 15 with Hypertensive heart disease (HHD) and 15 normal controls (N). M-mode echo cardiographic examination included IVS- LVPW echocadiogram 2 LA. On pulsed Doppler echo examination, mitral inflow velocity pattern E.A. E/A and pulmonary venous flow pattern PVS1, PVS2, PVD, PVA were studied. Pulsed Tissue Doppler Echocardiographic examination included velocity of mitral annulus motion S1, S2, EA E/A S2/E. Pulmonary artery wedge pressure was measured on cardiac cathetrization. The study results indicate that there is an excellent correlation between the early diastolic "EW" of MAM on TDI and diastolic wave of the pulmonary venous flow on TEE and also the early diastolic wave of trans mitral flow. There was a fair correlation between SW and the systolic wave of pulmonary venous flow. Results could not be compared with other researches, as there are no previous studies on this topic. If a few more studies confirm the validity of our results, TEE which is semi invasive technique and has some contra indications, can be replaced by TDI studies.
