Qualitative and quantitative evaluation of mitral valve morphology by intraoperative volume-rendered three-dimensional echocardiography.
OBJECTIVE
Two-dimensional echocardiography (2DE) performed to evaluate mitral valve anatomy during valve repair has certain limitations and pitfalls. The study aim was to assess the feasibility, accuracy and incremental value of three-dimensional echocardiography (3DE), coupled with 2DE in evaluating mitral valve structure, before and after repair and pericardial posterior annuloplasty.


METHODS
The site and extent of mitral valve prolapse, systolic and diastolic changes of mitral annular area were evaluated using 2D and 3D transesophageal echocardiography (TEE), both pre- and postoperatively in 34 patients before and after mitral valve repair and pericardial posterior annuloplasty.


RESULTS
Concordance between 2DE and surgery in evaluating prolapsing mitral valve scallops was 76% for the anterior leaflet and 75% for the posterior leaflet; for 3DE and surgery, concordance was 87% and 93% respectively. There was a significant reduction in maximal and minimal annular area after surgery, with a statistically significant difference between systolic-diastolic changes.


CONCLUSIONS
3DE, coupled with 2DE, is feasible and accurate in delineating the extent and location of prolapsing scallops of the mitral valve. The combined approach is also valuable in planning mitral valve surgery and evaluating the mitral valve annulus in vivo.
