Mayo Clinic case study: Cone reconstruction for Ebstein anomaly
This Mayo Clinic case study explores contemporary surgical management of Ebstein anomaly, a rare congenital condition characterized by extreme anatomic variability that makes operative repair uniquely challenging. Using comparative cardiac anatomy and long-term outcomes data, the video highlights cone reconstruction, a near-anatomic repair that mobilizes native leaflet tissue to create a functional funnel with leaflet-to-leaflet coaptation.
Viewers will gain insight into operative technique, including leaflet mobilization, creation of autologous neochordae, selective use of Gore-Tex chords, and tissue augmentation strategies when native leaflet tissue is limited. The case study also reviews durability and outcomes data demonstrating low early mortality and superior long-term freedom from reoperation compared with earlier monocusp repairs, reinforcing cone reconstruction as the preferred approach in appropriately selected patients.
