The Ross procedure offers superior hemodynamic performance and freedom from anticoagulation. While initially popular, utilization declined due to its technical complexity and concerns regarding the potential for the failure of two valves, requiring additional operations. Advances in surgical techniques, such as reinforced autografts, improved myocardial protection, and better homograft preservation, coupled with evidence of favorable long-term outcomes, have renewed interest in the procedure. Preoperative imaging with echocardiography, cardiac magnetic resonance imaging, and computed tomography angiography ensures optimal patient selection and preparation.
