Figure 1
A: The previous 12-lead electrocardiogram (ECG) showed Wenckebach second-degree atrioventricular block (* indicates P wave) and QT-interval prolongation. B: Ventricular fibrillation was recorded on ECG monitoring after admission to the hospital. C: Atrial flutter was observed after the cardioversion of ventricular fibrillation.
Figure 2
Figure 2
Contrast-enhanced computed tomography (CT) (A) and T2-weighted cardiac magnetic resonance imaging (MRI) (B) showed a 3-cm mass (red arrows) in the atrioventricular septal region, which was identified as a cystic tumor. LA = left atrium; LV = left ventricle; MV = mitral valve; RA = right atrium; RV = right ventricle; TV = tricuspid valve.
Figure 3
Figure 3
A: The resected cyst was unilocular (left), and contained a grayish white gel, as the sections show (right). B: Histology showed smooth muscle cell within the fibrous tissue wall of the cyst. The ciliated respiratory epithelium was also observed on the inner wall.
