Atresia of the tricuspid valve is constantly associated with a large interatrial communication and an underdeveloped right ventricle. The ventricle adjacent to the right atrium is usually represented by a solid mass of myocardium without a lumen and, therefore, remain unopacified on an angiocardiogram. The resulting triangular lucency between the contrast-filled right atrium and left ventricle is the angiocardiographic hallmark of tricuspid atresia.
