DE LA TORRE FONSECA, Luis M.; HECHEVARRIA POUYMIRO, Sheila  e  ECHEVARRIA SIFONTES, Lila A.. Cor triatriatum dexter and sinus venosus atrial septal defect: An infrequent association. CorSalud [online]. 2020, vol.12, n.4, pp. 441-444.  Epub 01-Dez-2020. ISSN 2078-7170.

Cor triatriatum is a rare congenital condition with a 0.1% prevalence among all cardiac congenital anomalies in which the heart is partitioned into three atria. In cor triatriatum dexter the right atrium is divided by a fibromuscular membrane into two parts, a proximal and a distal one, which may or may not communicate with each other. In the natural course of the condition, patients may remain asymptomatic until diagnosis or present with cardiovascular manifestations secondary to right heart failure and rhythm disorders. In the specific case of symptomatic patients, the treatment of choice would be surgical correction of the anomaly and sometimes percutaneous rupture of the membrane; while in asymptomatic patients, timely follow-up and treatment of their complications would seem to be the best alternatives.
