Quantification of Aortic Cusp Parameters Using Computed Tomography in Valve-Sparing Aortic Root Replacement Surgery: A Prospective Study

Purpose

Determining the feasibility of valve-sparing aortic root replacement (VSRR) requires accurate preoperative assessment of aortic valve cusp geometry. However, the reliability of computed tomography (CT) for measuring cusp parameters remains unclear. This study evaluated the agreement between CT-derived cusp measurements and intraoperative measurements and explored the potential of CT-based cusp asymmetry to predict intraoperative cusp plication.
