3D transesophageal echocardiographic assessment of cusp prolapse mechanisms in tricuspid aortic root aneurysms and correlation with valve-sparing surgical outcomes

Cusp prolapse-driven by heterogeneous mechanisms-is prevalent in tricuspid aortic valve root aneurysms and reduces the likelihood of successful VSRR. Preoperative 3D TEE quantification of cusp pathology can aid in surgical planning. Despite lower preservation rates in prolapse patients, both groups achieved comparable midterm outcomes following judicious patient selection.
