To evaluated intracardiac anomalies found as well as the planes used by MRI and CT in the cases with diagnosis of criss cross heart.

A retrospective review of clinical history and cardiac CT and MRI was made over the cases with diagnosis of criss cross heart, since October 2006 to February 2009, at the Hospital Cardiológico Infantil "Dr. Gilberto Rodriguez Ochoa"

Of a total of 669 patients with CT and cardiac MRI, 6 (0,8 %) had a diagnosis of criss cross heart, 4 cases was evaluated by MRI and 2 by CT. Regarding intracardiac abnormalities, 3 cases had double outlet tract of right ventricle, 1 of them associated with pulmonary atresia. In all cases, the upper ventricles were morphological right; in 1 case AV discordance was showed. Only 1 case did not present interventricular septal defect, 2 cases had transposition of great arteries, one of them with interrupted aortic arch; 1 case was found with left isomerism associated to partial anomalous venous drainage. With respect to the planes used; the horizontal long axis easily characterized the atrial-ventricular connection with the long axis vertical assessed ventricular arterial connection, and the short-axis allowed to evaluate the upper and lower ventricular disposition.

The total cases with criss cross heart evaluated during this period was higher than described in the literature (Sanders 2003). Of a total of 7 cases diagnosed with Criss Cross Heart was necessary to complete the evaluation with a MRI or CT studies in most cases (6 cases), due to doubt with it. The most frequently intracardiac anomalies associated were double outlet tract of right ventricle. Finally we recommend to use the horizontal long axis, the vertical long axis and the short axis multislice- multiphase covering around the heart for a full evaluation of this pathology.
