An isolated right ventricular hypertrabeculation and dyskinesia in an elderly man: A possible diagnosis of isolated right ventricular noncompaction?

A 69-year-old man admitted with mild chest distress and palpitation associated with activity. He underwent an initial 2DE that did not confirm HVM/NVM and 3DE that strengthened the diagnosis of HVM/NVM. The limitations of 2DE may lead to misinterpretation of prominent trabeculations as "false tendons," and may also lead to underestimation of the severity of HVM/NVM. In contrast to 2DE, 3DE provides for pyramid-shaped datasets that encompass the entire right ventricular. Specifically, right ventricular can be sectioned in userselected planes and an unlimited number and angles of such planes can be used. Intracavitary echodensities that are suspicious for trabeculations can be tracked in multiple directions from base to apex. The present case should be regarded as isolated right ventricular HVM/NVM because there were no any factors that could explain the arrest of the development of the myocardial structure. In addition, the prompt recognition of HVM/NVM could suggest the high risk of arrhythmogenesis in patients with HVM/NVM. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
