Could you give me some information about the cor triatriatum dexter?

Question: After suffering an episode of atrial fibrillation, several tests were indicated, including an echocardiogram, in which I was diagnosed with a disease called cor triatriatum dexter. Do you have information about this ailment? Eduardo (Malaga).

Answer: The condition you mention is a rare and complex congenital heart disease. Like almost all of them, it carries an increased risk, compared to the general population, of suffering arrhythmias, including atrial fibrillation. Occasionally the diagnosis in adults is made by discovering atrial fibrillation (AF). Given the low frequency of this heart disease, there are few data in this regard, generally derived from case series, many of them also referring to the left triatriatum (sinister). The recommended treatment is, therefore, difficult to specify, in general it would consist of antiacoagulation (unless contraindicated) and frequency or rhythm control (cases of successful ablation or disappearance of the arrhythmia – in paroxysmal AF – have been published after correction). surgical), as appropriate. In any case, it is recommended that the medical evaluation of your specific situation be given by an expert cardiologist in adult congenital heart disease, after weighing all the existing data specifically for you.
