Surgical repair of a giant congenital right atrial aneurysm: a case report

Abstract

Giant congenital right atrial aneurysms are rare defects of the heart. Though usually asymptomatic, they can be potentially life-threatening. Major risks include heart failure, supraventricular arrhythmias, rupture of the wall of the aneurysm. This defect is usually diagnosed incidentally. It is commonly found when transthoracic echocardiography or chest X-ray is performed. In some cases computed tomography or cardiac magnetic resonance imaging is needed to establish the diagnosis. Potential therapeutic options include surgery, catheter ablation and conservative follow-up. Currently preferred method for correcting this defect is surgical excision of the aneurysm, when surgical indications are met. In this article we describe a successful aneurysmectomy performed on a 16-month old female infant, who at the time of hospitalization presented with severe heart failure and symptoms of cardiac tamponade.

Congenital Aneurysm of the Right Atrium: Two Cases Report

“…[2] found 60 reported cases of right atrial aneurysm from which only 17 (28%) had been submitted to surgical treatment. Subsequently, sporadic cases have been described, including one of our experience [3-6] . In this article, we not only present another case, but probably more relevant, we describe the late results (17 years) of the surgery in the previously reported child.…”

Giant Right Atrial Aneurysm: Antenatal Diagnosis and Surgical Treatment

“…6 Having opted for surgical intervention, and taking into account the very large aneurysm, we preferred to use cardiopulmonary bypass, combined with normothermia and a beating heart, in order to decompress the heart and prevent any sudden rupture. Another consideration in favor of this form of surgical treatment was the previously reported finding 7 of huge dilatation of the right coronary artery, possibly separated from the right atrioventricular groove as proved to be the case in our patient. We can only speculate that the right coronary artery dilatation follows the huge dilatation of the right atrium.…”
