Relevance of subtle echocardiographic findings in the early diagnosis of the concealed form of right ventricular dysplasia.
Right ventricular dysplasia (RVD) is an important cause of arrhythmic sudden death in young people. Echocardiographic criteria suggestive of RVD were: dilation of RV, localized bulge and dyskinesia of the inferobasal wall, structural changes of the moderator band, isolated enlargement of RV outflow tract, apical dyskinesia and trabecular disarrangement. Among 136 subjects 'at risk of high incidence of RVD', 40 had a suggestive echocardiogram. 90% of these showed lipomatous transformation at biopsy and/or developed serious ventricular arrhythmias during a mean follow-up of 42 months. Thus, echocardiography is a potent method in detecting myocardial pathology due to RVD.
