Myocardial noncompaction (NC) is a disorder of the embryonic endomyocardial morphogenesis frequently associated with congenital cardiac abnormalities. NC predominantly affects the left ventricle (LV). Right ventricle (RV) NC may occur in association with LV involvement or in isolation. A 47-year-old woman was admitted for atrial septal defect closure. Transthoracic echocardiography revealed hypertrabeculation of the RV apex, consisting of multiple deep recesses with the entrance of blood flow in color Doppler imaging, suggestive of isolated RV hypertrabeculation/NC. The RV and right atrium (RA) were enlarged, and systolic pulmonary arterial pressure was slightly increased. Our patient's associated abnormalities were atrial septal defect (superior sinus venosus type), anomalous connection of the right upper pulmonary vein to the junction of the superior vena cava and the RA, and large patent foramen ovale. Association between atrial septal defect and partial anomalous pulmonary vein connection and isolated hypertrabeculated/noncompacted RV should be considered by cardiologists.
