[Transthoracic and transesophageal comparative echocardiography in mitral valve prolapse].
OBJECTIVE
Transthoracic and transesophageal comparative analysis of functional and morphological abnormalities associated to idiopathic mitral valve prolapse (MVP).


METHODS
Prospective study.


METHODS
Outpatients with MVP diagnosis referred to echocardiographic laboratory of Cardiology Institute in Madrid, Spain.


METHODS
In each case we analyzed by TTE and TEE, anterior, posterior and double localization of MVP, number of prolapsed mitral leaflets/patient, total area of MVP to mitral valve plane, mitral annulus diameter, total area and spatial distribution of mitral regurgitation.


RESULTS
TEE diagnosed a greater number of prolapsed mitral leaflets and a greater percentage of double (80%) MVP. MPV area by TEE (50 +/- 31 mm2) was considerably larger (96 +/- 30 mm2) than TTE MVP area (50 +/- 31 mm3. Associated mitral valve regurgitation area calculated through TEE was larger (558 +/- 502 mm2) than the same parameter evaluated by TTE (450 +/- 515 mm2).


CONCLUSIONS
TEE is an efficient technique in MVP non invasive diagnosis and particularly sensitive to posterior MVP. Our data could be helpful in MVP cases scheduled for mitral valve repairment.
