Plenary I: Key Foundations | Recorded at the AATS Mitral Conclave 2025
Plenary I: Key Foundations, facilitated at the 2025 AATS Mitral Conclave, introduces the historical and conceptual pillars that underpin contemporary mitral valve surgery. This recorded session features welcome remarks from AATS leadership and the 2025 AATS Mitral Conclave Program Committee, followed by landmark perspectives on the evolution of mitral valve replacement and repair. Foundational principles established by Carpentier and Frater are explored, highlighting innovations such as chordoplasty that transformed surgical durability and outcomes. The plenary also reviews Cox’s seminal contributions to the surgical management of atrial fibrillation and the left atrial appendage. An expert discussion synthesizes these enduring concepts and their relevance to current practice.
