Abstract
Cardiomyopathies are diseases of cardiac muscles associated with cardiac dysfunction, classified by WHO according to pathophysiology to dilated cardiomyopathy (64% of childhood cardiomyopathies), hypertrophic cardiomyopathy (28% of childhood cardiomyopathies), restrictive cardiomyopathy, arrythmogenic RV cardiomyopathy, and unclassified (specific cardiomyopathy). Tissue Doppler imaging is a new ultrasound technique that uses shifts in Doppler frequencies for quantifing myocardial motion. As it doesn?t depend on the amplitude of the reflected wave, it is possible to get information regarding myocardial wall motion from an area that may not have satisfactory gray scale information on (2D) echocardiography. Also it doesn?t depend on the loading conditions We conducted our study on 20 patients with DCM (8 male and 12 female), 10 patients with HCM (6 male and 4 female), and 20 healthy control (13 male and 7 female) by assessment of clinical status (HF), cardio0thoracic ratio by plain chest xray posteroanterior view, 12 lead ECG, PWDoppler echocardiography of transmitral (E, A, E/A) and transtricuspid (E, A, E/A) and LV EF%, and PWTDI of mitral annular and tricuspid annular systolic (S), diastolic (E`/A`, E`/A`) and overall systolic and diastolic ventricular function (Tei index), and lateral mitral annulus (E/E`) ratio and we found that PWTDI is superior than PWDoppler echocardiography in assessing both systolic and diastolic specially diastolic functions of both LV and RV in both DCM and HCM groups.
