3D TEE with direct planimetry is proposed as a highly accurate and less variable method for measuring mitral valve area in rheumatic mitral stenosis compared to conventional 2D TTE.
DEAR EDITOR,Three-dimensional (3D) transesophageal echocardiography (TEE) is a powerful tool for assessment of mitral valve area with multiplanar reconstruction (MPR) or direct planimetery in patients with rheumatic mitral valve stenosis. Two dimensional transthorasic echocardiography (2D TTE) is a well-known conventional method in these patients which is used routinely. This method is less accurate than 3D TEE because mitral valve is saddle shaped and 2D images cannot image this valve correctly [1-7]. Exact method for 3D mitral valve area measurement is not determined yet and MPR was used as an accurate method. Direct planimetery by 3D TEE emerged as a novel method to evaluate mitral valve area with least variability [8].

Direct planimetry by Three-Dimensional Transesophageal Echocardiography (3D TEE) vs. Multiplanar reconstruction (MPR) and 2D Transthoracic Echocardiography (2D TTE) was evaluated on Accuracy of mitral valve area measurement. Direct planimetry by 3D TEE is highlighted as a novel and accurate method to evaluate mitral valve area with minimal variability in patients with rheumatic mitral valve stenosis.
