Isolated Congenital Right Atrial Aneurysm: Monitoring Parameters for Asymptomatic Patients

Abstract

Isolated congenital right atrial aneurysm is rare. Indications for surgery in asymptomatic patients with moderate-size right atria remain controversial. Evidence in support of medical management and timing of prophylactic surgery is reviewed. We propose the use of three echocardiographic indices to help identify inappropriate atrial growth and facilitate surgical decision-making.
