Background: Recent advances in three-dimensional (3D) echocardiography allow to obtain real-time 3D transesophageal (RT3DTEE) images intraoperatively. Methods: Preoperative transthoral echocardiography (TTE) revealed: hypertrophic ventricular septum (TTE:19.3 mm), systolic anterior motion (SAM) not causing obstruction and malcoaptation of the anterior mitral valve leaflet (AMVL), and posterior mitral valve leaflet (PMVL) with severe mitral regurgitation. Results: Intraoperative TEE with a x7-2t MATRIX-array transducer (Philips, Andover, MA, USA) with a transducer frequency of x7-2 t mHz, connected to a iE33 (Philips), shows us that the main mechanism and site of regurgitation was an AMVL cleft. We also measured a 24.3-mm thickness of the ventricular septum and analyzing the 3D full volume acquisition revealed that there was no SAM. Conclusion: Intraoperative RT3DTEE permitted comprehensive 3D viewing of the mitral valve revealing the mechanism of mitral valve regurgitation, SAM, and the exact width of the hypertrophic ventricular septum.
