	Introduction

Top Introduction

 
A 26-year-old obese woman presented with progressive exertional dyspnea and cyanosis. Visualization of the heart by transthoracic echocardiography was suboptimal; therefore, transesophageal echocardiography was performed. This revealed a complete lack of any atrial septal tissue (single atrium). The right ventricle was enlarged. Mitral and tricuspid valve attachments to the interventricular septum were in the same anatomic plane, but a cleft mitral valve was not present.

The patient was referred for surgery, and a pericardial patch was used successfully to create an interatrial septum.
