Cardiovascular magnetic resonance imaging findings in Ebstein anomaly


In recent years, cardiac magnetic resonance (CMR) imaging has emerged as the reference standard for cardiac imaging in patients with many forms of congenital heart disease, in particular for lesions that affect the right ventricle. Few studies have been published in assessment of Ebstein anomaly by CMR imaging.


CMR studies of patients with EA conducted from June 2007 to June 2011 were analized. Cine spin echo images in multiple views, and angiography were evaluated to assess chambers morphology and diameters, wall thickness and left ventricular function, also were measured the atrialized right ventricular portion and the functional tricuspid valve position. And Inversion Recovery sequence for determination of fibrosis.


Ninety four patients were studied. Table 1 summarizes the main results. Tricuspid valve regurgitation was found in 96.9%, severe in 62. 5% of the cases. The presence of left ventricle fibrosis was significant associated with right ventricle longest dimension including the atrialized portion (p=0.003), the diastolic and systolic diameters (p=0.011 and p=0.005).

Table 1 Results


CMR findings in EA were demonstrated. There was a clear positive relationship between the presence of LV fibrosis and the right ventricle dimensions.
