title: Intermittent right coronary artery obstruction.
abstract: Although prospectively electrocardiogram-triggered acquisition is frequently used for coronary CT angiography examinations in routine clinical practice to achieve low radiation dose, the use of retrospectively electrocardiogram-gated techniques may be useful for cases that potentially have a dynamic temporal element or involve the valves. In this case of a valvular fibroelastoma, CT could demonstrate dynamic obstruction of the right coronary ostium.
