The routine use of live three-dimensional transesophageal echocardiography in mitral valve surgery: clinical experience.
BACKGROUND
Perioperative monitoring of mitral valve (MV) anatomy, function, and pathology is essential for surgical management of different MV disease.


OBJECTIVE
To overcome the several potential pitfalls of two-dimensional transesophageal echocardiography (2D TEE) and offline 3D TEE.


METHODS
Live 3D TEE was used to assess 73 patients (44 men and 29 women) with Carpentier type II MV regurgitation undergoing MV surgery perioperatively.


RESULTS
The isolated segment most frequently involved was A2/P2, but A1or P1 rarely was involved in an isolated lesion or combined lesions. The agreement between 3D TEE finding and surgery was 88% (64/73). In nine patients, the live 3D TEE images revealed more segments or scallops with prolapse than the surgeon noted intraoperatively.


CONCLUSIONS
Live 3D TEE allows more sensitivity and was feasible identification of prolapse or flail of individual segments of MV leaflets during surgery. We conclude that live 3D TEE should be regarded as an important adjunct to the standard 2D TEE examination in making decisions about MV surgery.
