Abstract
Ebstein anomaly is the most common form of tricuspid valve congenital anomalies. The tricuspid valve is abnormal with different degrees of displacement of the septal leaflet and abnormal rotation of the valve towards the right ventricular outflow tract. In severe forms, it results in significant tricuspid regurgitation and requires surgical repair. There is an increased interest in understanding the anatomy of the tricuspid valve in this lesion as the surgical repair has evolved with the invention and wide adoption of the cone operation. Multimodality imaging plays an important role in diagnosis, follow-up, surgical planning and post-operative care. This review provides anatomical tips for the cardiac imagers caring for patients with Ebstein anomaly and will help provide image-based personalized medicine.
