A 9-year old girl was admitted for palpitations. Multiple noninvasive imaging studies (Videos 1 and 2, Fig. 1A–C) demonstrated a giant congenital left atrial aneurysm with mitral regurgitation.

Video 1: Transthoracic echocardiography before surgery. This video showed the giant left atrial aneurysm and there was severe isolated mitral regurgitation.

Left atrial plication and mitral valvuloplasty were performed. Imaging after surgery (Fig. 1D–F) showed a good outcome and the patient was discharged without complications.

Video 2: The two-chamber view of cardiac magnetic resonance cine imaging before surgery. The two-chamber view of cine imaging by steady-state free precession sequence showed the giant left atrial aneurysm with a normal atrial appendage. The location of the left ventricle was distorted by the aneurysm. There was severe mitral regurgitation.

Figure1: (A) Postero-anterior (PA) view of chest radiography showed an enlarged left atrium. (B) Axial view of cardiac dual-source computed tomography (CT) scan demonstrated a giant aneurysm of the left atrium (red arrow) with a size of 92 × 92 × 95 mm. (C) Three-dimensional volume rendering reconstruction image demonstrated the left atrial aneurysm (red arrow) with normal pulmonary venous drainage. (D) PA view of chest radiography after atrial plication and mitral valvuloplasty showed an almost normal cardiac silhouette. (E and F) Axial view of cardiac CT scan and a 3D volume rendering reconstruction image demonstrated a nearly normal left atrium with a size of 45 × 33 × 34 mm and appropriate location.
