Dynamic Three-Dimensional Geometry of the Aortic Valve Apparatus – A Feasibility Study

Objective To provide 1) an overview of the aortic valve (AV) apparatus anatomy and nomenclature, and 2) data regarding the normal AV apparatus geometry and dynamism during the cardiac cycle obtained from three-dimensional transesophageal echocardiography (3D TEE).

Description
Summary:Objective To provide 1) an overview of the aortic valve (AV) apparatus anatomy and nomenclature, and 2) data regarding the normal AV apparatus geometry and dynamism during the cardiac cycle obtained from three-dimensional transesophageal echocardiography (3D TEE). Design Retrospective feasibility study. Setting A single center university teaching hospital. Participants The study was performed on data of 10 patients with a non-regurgitant, non-stenotic aortic valve undergoing cardiac surgery. Interventions Intraoperative 3D TEE was performed on all the participants using the Siemens ACUSON SC2000 ultrasound system and Z6Ms transducer. Measurements and Main Results Dynamic offline analyses were performed with Siemens eSie Valve analytical software in a semi-automated fashion. Forty-five parameters were exported of which 13 were selected and analyzed. The cardiac cycle was divided into 4 quartiles to account for frame rate variations. The annulus, sinus of valsalva (SoV) and sino-tubular junction (STJ) area, diameter, perimeter & height, aortic leaflet height, leaflet coaptation height and AV-MV angle changed significantly during the cardiac cycle (p
