CASTANO, Orlando et al. Aorta-to-right atrium fistula: an unusual presentation. Rev. Colomb. Cardiol. [online]. 2018, vol.25, n.4, pp.280-280. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2018.02.002.

Aorta-to-atrium fistulas are rare anatomical anomalies, of a multifactorial aetiology. The most common cause in the adult population is due to endocardial infections. They can present as cardiac failure, ranging from pulmonary hypertension to being asymptomatic, and being precipitated by any stressful event. The diagnostic method of choice is echocardiography, and depending on its location, the transthoracic or trans-oesophageal mode would be better. Endovascular and surgical repairs of the fistulas have been described. This latter technique is the most used because, as previously mentioned, the most common origin is an endomyocardial infection.
