Abstract 3187: Is There A Role For Three Dimensional Transthoracic Echocardiography In The Preoperative Assessment Of The Mitral Valve?
Background: Transesophageal echocardiography (TEE) is the gold standard in determining preoperative mitral valve morphology for surgical repair, but is invasive and time consuming. We evaluated the ability of 3D transthoracic echocardiography (TTE) to assess the mitral valve in patients undergoing mitral valve repair and compared this with 2D TEE.
Methods: Patients with severe mitral regurgitation (MR) underwent 2D followed by 3D TTE and 2D TEE preoperatively. Echocardiographic data was obtained by the different techniques and compared with surgical inspection.
Results: 63 consecutive MR patients underwent preoperative analysis (55 degenerative, 8 rheumatic, sinus rhythm 69%). TTE 3D images were feasible in the majority (good quality 45%, adequate 46%, poor 9%). Acquisition time was (3mins ±2). The sensitivities and specificities of each technique to diagnose scallop lesions are given below. 3D TTE and 2D TEE had similar diagnostic accuracies (accuracy 91% v 88% respectively p=ns).
Conclusion: 3D TTE gives the same information as 2D TEE in assessment of mitral valve morphology and is feasible in the majority.
