Atrial septal aneurysm, Mitral Valve Prolapse Syndrome, Echocardiography, Real Time-3D-Echocardiography
A 68-year-old male presented to the out-patient clinic with history of intermittent palpitations and fatigability for past seven months. On cardiovascular system examination, mid-systolic click and pan-systolic murmur grade III/VI were audible at the apex with radiation to the base of heart. Echocardiographic study revealed atrial septal aneurysm (Figure 1, Figure 2, Video 1 and Video 2), along with prolapse of Posterior Mitral Leaflet (PML) into left atrium (Figure 3 and Figure 4). Color-doppler echocardiography revealed severe eccentric mitral regurgitation MR) jet impinging on atrial septal aneurysm with vena-contracta width of 10.9 mm (Figure 4 and Video 3).
Atrial Septal Aneurysm (ASA) is a congenital deformity of the inter-atrial septum with a prevalence of 1-2% in the adult population. It is usually associated with Patent Foramen Ovale (PFO), Atrial Septal Defect (ASD), Mitral Valve Prolapse Syndrome (MVPS), TVPS, Marfan's syndrome and aortic dissection.
