[Localization of mitral valve prolapse zones with multiplane transesophageal echocardiography]

There are few literature data on the localization and extent of mitral valve prolapse zones with transesophageal echocardiography (TEE).

To assess a standardized imaging technique for the localization and extent determination of prolapse zones, based on 3 easily reproducible views with multiplane TEE.

Seventy patients with severe mitral regurgitation due to valve prolapse requiring a multiplane TEE prior to surgery (valve repair or replacement) have been retrospectively assessed. Data of TEE on the localization and extent of prolapse zones have been confronted to per-operative anatomical observations (gold standard).

The sensitivity of TEE for the identification of isolated P2 prolapse, prolapse with commisural extension, isolated rupture of the posterior commisure and bi-valvular prolapses were respectively at 96%, 88%, 86% and 80%. The corresponding specificities were from 98% to 100%.

The use of a standardized technique with the use of 3 easily reproducible incidences with multiplane TEE allows a precise definition of the localization and extent of mitral valve prolapse zones, in order to potentially indicate valve repair.
