BACKGROUND: Right ventricular (RV) chamber involvement has been demonstrated in @entity1121 ( @entity1121 ) as well as in @entity101 @entity4346 ( @entity4346 ) but little is known about RV @entity296 occurring in these two pathologies. The aim of this study was to compare Doppler tissue imaging (DTI) of the right ventricle in @entity1121 and @entity4346 in relation to DTI of the left ventricle and Doppler standard of the RV and left ventricular (LV) inflow. METHODS: Thirty controls, 20 @entity101 with @entity4346 , and 23 @entity1 with @entity1121 involving the interventricular septum underwent Doppler echocardiography and pulsed DTI of the LV lateral mitral annulus and the RV lateral tricuspid annulus. RESULTS: @entity1 with @entity1121 had a higher blood pressure, septal thickness and LV mass in comparison with the other two groups. The RV wall thickness did not differ between @entity1121 and @entity4346 . The fractional shortening, but not the tricuspid annular plane excursion, was higher in @entity1121 . After adjusting for the mean blood pressure, the Doppler-derived global LV and RV diastolic functions were more impaired in @entity1121 than in @entity4346 . Also the majority of DTI LV and RV diastolic measurements were altered more in @entity1121 . At the RV tricuspid annulus, myocardial diastolic indexes were @entity4346 in comparison with controls but the deceleration and relaxation times distinguished also @entity1121 and @entity4346 , being much longer in @entity1121 (p < 0.0001). In the overall population, the RV myocardial relaxation time was positively related to the septal wall thickness and the RV wall thickness, even after adjusting for age, heart rate, diastolic blood pressure, fractional shortening and DTI mitral relaxation time. CONCLUSIONS: The impairment of RV myocardial relaxation is much more evident in @entity1121 than in @entity4346 , its degree being independently associated with the extent of both the septal and RV wall thickness. Pulsed DTI may be useful to distinguish the extent of RV @entity296 in different types of @entity1283 .
