Few case reports describe their rare complications including aneurysmal dissection into the muscular interventricular septum with resultant arrhythmias, heart block, (22) and infective endocarditis (23).
Caption: Figure 4: Axial cardiac computed tomography images at the level of the interventricular septum and base of the heart (a) showing fatty infiltration of the right ventricular side of the septum extending into the adjacent trabeculae (red arrow).
The minor criteria were as follows: thin endomyocardial patches localised to one ventricular wall (1); restrictive flow pattern across mitral or tricuspid valves (2); pulmonary valve diastolic opening (2); diffuse thickening of the anterior mitral leaflet (1); enlarged atrium with normal-size ventricle (2); m-mode movement of the interventricular septum and flat posterior wall (1); and enhanced density of the moderator or other intraventricular bands (1).
The dimension of the ventricular chamber is reduced, the interventricular septum thickens, and patients suffer from diastolic dysfunction (in which heart muscle doesn't relax normally), causing an increased risk of sudden death from arrhythmia.
There was no difference between the groups regarding left ventricular end-diastolic dimension, left ventricular end-systolic dimension, interventricular septum thickness in diastole, interventricular septum thickness in systole, left ventricular posterior wall thickness in diastole, left ventricular posterior wall thickness in systole, left atrium dimension, aortic dimension, ejection fraction, and fractional shortening.
