We attempted to establish if multiplane transesophageal echocardiography (TEE) improves accuracy of parameters to predict the surgical decision to perform mitral valve (MV) repair versus replacement compared to transthoracic echocardiography (TTE). In the last two years TTE and TEE studies were performed in 38 patients (pts), aged 19 to 76 years (mean 55 years), with MV regurgitation who underwent surgery (MV repair 22 pts, MV replacement 16 pts). The following echocardiographic parameters were evaluated: leaflet mobility and thickness, chordal length and rupture, MV annular size, MV regurgitant jet, left atrial size, left ventricular dimensions and function. There was a significant increase in annular diameter in pts who underwent MV repair compared to pts who underwent MV replacement, both by TTE and TEE (TTE: 48 +/- 9 vs 38 +/- 14 mm, p< 0.005; TEE: 47 +/- 9 vs 35 +/- 9 mm, p< 0.001). A significant increase in chordal length was found only by TEE (TTE: 38 +/- 9 vs 26 +/- 8 mm, p< 0.001). Discriminant analysis showed that MV repair versus MV replacement was correctly predicted by TTE in 18 out of 38 pts (47%) with a sensitivity of 70%, specificity of 64% and PPV of 67%. MV repair versus MV replacement was correctly predicted by TEE in 32 out of 38 pts (84%) with a sensitivity of 84%, specificity of 90% and PPV of 91%. Thus, TEE improves the accuracy of parameters indicating the opportunity to perform MV repair instead of replacement.

Abstract
We attempted to establish if multiplane transesophageal echocardiography (TEE) improves accuracy of parameters to predict the surgical decision to perform mitral valve (MV) repair versus replacement compared to transthoracic echocardiography (TTE). In the last two years TTE and TEE studies were performed in 38 patients (pts), aged 19 to 76 years (mean 55 years), with MV regurgitation who underwent surgery (MV repair 22 pts, MV replacement 16 pts). The following echocardiographic parameters were evaluated: leaflet mobility and thickness, chordal length and rupture, MV annular size, MV regurgitant jet, left atrial size, left ventricular dimensions and function. There was a significant increase in annular diameter in pts who underwent MV repair compared to pts who underwent MV replacement, both by TTE and TEE (TTE: 48 +/- 9 vs 38 +/- 14 mm, p< 0.005; TEE: 47 +/- 9 vs 35 +/- 9 mm, p< 0.001). A significant increase in chordal length was found only by TEE (TTE: 38 +/- 9 vs 26 +/- 8 mm, p< 0.001). Discriminant analysis showed that MV repair versus MV replacement was correctly predicted by TTE in 18 out of 38 pts (47%) with a sensitivity of 70%, specificity of 64% and PPV of 67%. MV repair versus MV replacement was correctly predicted by TEE in 32 out of 38 pts (84%) with a sensitivity of 84%, specificity of 90% and PPV of 91%. Thus, TEE improves the accuracy of parameters indicating the opportunity to perform MV repair instead of replacement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
