The \"cone procedure,\" introduced by Dr. Jos\u00e9 Pedro da Silva, represents a major advancement in the repair of Ebstein\u2019s anomaly, achieving near-anatomical tricuspid valve reconstruction. We describe the case of a 23-year-old-female with Carpentier type B Ebstein\u2019s anomaly, severe tricuspid regurgitation and Wolff-Parkinson-White syndrome, who underwent cone reconstruction combined with right ventricular resection. Detailed preoperative imaging guided the procedure, ensuring precise leaflet mobilization, delamination and cone creation. The atrialized right ventricular portion was reduced via triangular resection, preserving right ventricular geometry. An annuloplasty ring stabilized the repair. Postoperatively, the patient demonstrated excellent recovery, with trivial regurgitation and preserved right ventricular function confirmed at the one-year follow-up. This case highlights the reproducibility and effectiveness of the cone repair, supporting its role as the primary surgical approach for Ebstein\u2019s anomaly. Key factors for success include meticulous leaflet delamination, ensuring a complete 360\u00b0 cone structure and maintaining RV geometry. Although long-term outcomes require further evaluation, the cone procedure offers superior valve competence and symptom relief compared to traditional repairs, minimizing the need for reoperation.<\/jats:p>","DOI":"10.1510\/mmcts.2025.116","type":"journal-article","created":{"date-parts":[[2025,11,19]],"date-time":"2025-11-19T11:03:17Z","timestamp":1763550197000},"source":"Crossref","is-referenced-by-count":0,"title":["Cone repair and right ventricular resection in an adult patient with Ebstein\u2019s anomaly"],"prefix":"10.1510","member":"10966","published-online":{"date-parts":[[2025,11,19]]},"container-title":["Multimedia Manual of Cardio-Thoracic Surgery"],"original-title":[],"deposited":{"date-parts":[[2025,11,19]],"date-time":"2025-11-19T11:03:17Z","timestamp":1763550197000},"score":1,"resource":{"primary":{"URL":"https:\/\/mmcts.org\/tutorial\/2121"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,19]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1510\/mmcts.2025.116","relation":{},"ISSN":["1813-9175"],"issn-type":[{"value":"1813-9175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11,19]]}}}
