Ten @entity1 with @entity3822 were studied echocardiographically with specific reference to inter-ventricular septal dynamics. @entity910 of the interventricular septum was present in 8 @entity1 and consisted of flattening in systole and unusual posterior motion in diastole. The aetiology of this type of movement is at present unknown but may be related to restriction of normal cardiac rotational dynamics. The interventricular septum also showed diminished degree of thickening (mean 21-2%). The amplitude of excursion was generally at the upper limit of or greater than normal. Left ventricular posterior wall amplitude of excursion was normal. Flattening of left ventricular posterior wall diastolic movement was seen in 4 @entity1 . Right ventricular end-diastolic dimension was slightly increased (1-2 to 1-7 cm/m2) in 5 of 8 @entity1 with @entity1757 , but no haemodynamic evidence of diastolic @entity1284 was found. Posterior pericardial thickening was noted echocardiographically when posterior calcification was present. We conclude that the most common though non-specific feature of the echocardiogram in @entity1 with @entity3822 is @entity1757 . Flattening of left ventricular posterior wall diastolic movement, posterior pericardial thickening, and @entity2294 may also occur.
