OBJECTIVE: Transthoracic and transesophageal comparative analysis of functional and morphological abnormalities associated to idiopathic mitral valve prolapse (MVP).
DESIGN: Prospective study.
SETTING: Outpatients with MVP diagnosis referred to echocardiographic laboratory of Cardiology Institute in Madrid, Spain.
MATERIAL AND 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.
