Noninvasive techniques like echocardiography and radionuclide scintiscanning can successfully diagnose rare congenital left atrial appendage aneurysms, guiding surgical intervention.
May support noninvasive diagnosis of rare left atrial appendage aneurysm; leaves open prospective validation before broader adoption.
Congenital left atrial appendage aneurysm is rarely diagnosed on the basis of an abnormal cardiac silhouette. Patients with a left atrial appendage aneurysm often present with symptoms of systemic emboli or supraventricular arrhythmias. A patient with left atrial appendage aneurysm was diagnosed by correlation of two noninvasive techniques echocardiography and radionuclide scintiscanning. Angiography was confirmatory and aneurysmectomy was successfully performed.
