ROSALES UVERA, Sandra Graciela; MORELOS GUZMAN, Martha  and  VAZQUEZ LAMADRID, Jorge. Useful of cardiovascular magnetic resonance in diagnosis of cor triatriatum dexter: Case report. Rev. Mex. Cardiol [online]. 2012, vol.23, n.1, pp.12-16. ISSN 0188-2198.

The Cor triatriatum dexter is a strange pathology, the main data have been obtained only like case report postmortem study, when we find this pathology during the magnetic resonance study of a patient with severe pulmonary stenosis, who were send for evaluation of right ventricular function, without report of Cor triatriatum in other image studies, it increase the interest of the analysis and revision of the literature. The incidence of Cor triatriatum dexter is approximately 0.025% of the cases of the congenital heart disease and it is the result of the persistence of the embryonic valve of the venous sine. During the magnetic resonance study, in images of spin-echo is observed the membrane that divides the right atrium, also that during a first-pass contrast is corroborated that this membrane is fenestrated when observing turbulent flow among the true atrium and the false one, besides that the magnetic resonance allowed the appropriate evaluation of the right ventricular function. Although the Cor triatriatum is not very common it usually accompanies the pulmonary stenosis, the magnetic resonance allowed its appropriate evaluation thanks to its resolution, we can confirm its importance in the valuation of congenital heart disease.

Keywords : Cor triatriatum; cardiovascular magnetic resonance; pulmonary stenosis.
