This clinical trial, a prospective, randomized, multicenter study, assigns patients to either videodensitometry-guided TAVI or conventional TTE/TEE-guided TAVI (stand of care), with the primary endpoint being regurgitation fraction measured by cardiac magnetic resonance (CMR) at discharge. Current AR assessment methods, like subjective visual grading or intraprocedural TTE, face limitations in objectivity and practicality, whereas videodensitometry offers real-time, quantitative feedback to guide corrective actions (e.g., post-dilation) during TAVI. If proven non-inferior, this approach could streamline workflows by reducing reliance on general anesthesia and complex imaging, potentially lowering complications and expanding accessibility, particularly in centers lacking advanced echocardiography resources.
