Atrial septal defect (ASD) is a form of congenital heart defect that enables blood flow between the left and right atria via the interatrial septum it is possible for blood to travel from the left side of the heart to the right side of the heart, or vice versa. This results in the mixing of arterial and venous blood, which may or may not be clinically significant.
Mitral valve prolapse (MVP) may be defined as an abnormal protrusion or bulging of mitral valve leaflet segments into the left atrium past the plane of the mitral annulus during ventricular systole. In typical MVP, the free leaflet edges point toward the left ventricle during systole. In more severe forms of MVP, the free edges of mitral leaflets may lose their chordal support and evert into the left atrium during systole. When that occurs, the mitral valve leaflet is said to be flail.
A number of studies have demonstrated the feasibility of 3DE in optimally displaying mitral valve prolapse,The accuracy of 3DE in localizing the involved leaflets has been confirmed at surgery.3DE might also improve the diagnostic sensitivity and specificity in mitral valve prolapse Reconstruction of the mitral valve en face from the left atrial perspective provides a view of the valve similar to that seen intraoperatively by the cardiac surgeon, with the major advantage of displaying the dynamic motion of the valve within the beating heart Clearly,3DE has great potential to facilitate the preoperative planning of mitral valve repair.
Our study includes the study of ASD patients referred for ASD device closure in the Cardiac Catheterization laboratory in Cairo University Children Hospital
during the period from March ,2012 to October ,2013 they are 32 patients divided into:
ASD patients without MVP: included 21 cases of ASD without MVP (8 male and 13 female).
ASD patients with MVP (study group): included 11 cases of ASD with MVP (3 male and 8 female).
Our study showed that the Frequency of mitral valve prolapse in ASD patients was 34.37% which was statistically significant (P value |
