title: Arrhythmogenic right ventricular dysplasia presenting with ventricular tachycardia in a father and son.
abstract: A father and his son presented with ventricular tachycardia of left bundle-branch block configuration, two years apart. The patients had no clinical signs of right or left ventricular dysfunction. The diagnosis of arrhythmogenic right ventricular dysplasia was based on right ventricular angiographic and radionuclide findings. Microscopic sections obtained at surgery for the ventricular tachycardia in the father revealed abnormal infiltration of fat and focal fibrosis in the right ventricular myocardium, confirming the diagnosis. The importance of thorough evaluation of right and left ventricular function and structure in patients with ventricular tachycardia of right ventricular origin is emphasized. Currently available diagnostic techniques and management are presented.
