Resumen

We report a case of cor triatriatum sinister associated with anomalous pulmonary venous drainage in an adult patient who presented with palpitations, lower-limb edema, dyspnea, orthopnea, bendopnea and ascites. The clinical presentation began with episodes of atrial fibrillation, associated with readmissions for right heart failure, so angiotomography and transesophageal echocardiography were requested, which led to the final diagnosis. The surgical approach was performed by total excision of the multiple fenestrations of the fibromuscular septum and double valvular plasty due to severe mitral and tricuspid insufficiency, which improved the patient’s clinical condition. It´s important to consider this acyanotic congenital heart disease in the differential diagnosis of right heart failure´s etiology originating in the left atrium.
