Guidance on 3D TEE Probe for Subaortic Surgery

This case report details the use of a 9VT-D mini 3D transesophageal echocardiographic (TEE) probe in the preoperative evaluation of a 9-year-old patient with recurrent subaortic membrane. The report outlines the challenges faced by surgeons in visualizing the three-dimensional extent of the subaortic membrane and its relationship to the aortic valve leaflets using standard two-dimensional echocardiographic imaging. The procedure involved a preoperative 4D TEE that delineated the circumferential subaortic membrane, leading to successful membrane resection. Postoperative evaluations indicated no residual stenosis and improved hemodynamics, confirmed by Blood Speckle Imaging (BSI). The findings suggest that the 9VT-D mini 3D TEE probe enhances the understanding of anatomical relationships in complex cases, facilitating personalized surgical approaches. Follow-up evaluations showed favorable outcomes, including trivial regurgitation and improved leaflet motion, demonstrating the effectiveness of this imaging technique in guiding surgical interventions.
