Right-sided heart failure was diagnosed in a young dog with clinical and pathologic features of isolated right ventricular cardiomyopathy. This disorder, also referred to as right ventricular dysplasia, is an infrequent cause of heart failure and sudden death in people. Echocardiography of this dog revealed right ventricular and right atrial dilatation and severe right ventricular systolic dysfunction. Left ventricular size and function were normal. Electrocardiography revealed ventricular bigeminy. The configuration of the ectopic beats was similar to that seen with left bundle branch block. The dog died suddenly, and histologic examination of the heart revealed fibroadipose replacement of right atrial and right ventricular myocardium.
一只年轻犬被诊断为右侧心力衰竭，具有孤立性右心室心肌病的临床和病理特征。这种疾病，也被称为右心室发育异常，是人类心力衰竭和猝死的罕见原因。这只犬的超声心动图显示右心室和右心房扩张以及严重的右心室收缩功能障碍。左心室大小和功能正常。心电图显示室性二联律。异位搏动的形态与左束支传导阻滞时所见相似。这只犬突然死亡，心脏组织学检查显示右心房和右心室心肌被纤维脂肪组织替代。
