Abstract:
Assessing the normal thickness of mitral valve leaflets is very important to help the surgeon during operation to assess the exact mechanical reason for valve insufficiency and any inflammation and thickening that change the morphology of mitral valve leaflets. The aim of this study was to evaluation of morphology of mitral valve leaflets thickness in Sudanese using echocardiography and correlates it with age, sex, leaflets motion, leaflets calcification and subvavular thickening, in order to account for the variation in respect to International Index.
It was carried out on one hundred, classified into fifty normal and fifty abnormal patients in Sudan-Khartoum-Khartoum Hospital. The study was conducted from July 2012 up to November 2013.The machines used in the study were high resolution real time scanner (Siemens acuson cv70) with a 3.5MHz convex transducer. The measurements of mitral valve leaflets thickness were done in millimeters and scanning was performed in left lateral decubitus position with the upper body slightly elevated.
The data was collected, classified and analysis of the results found that the female in this study with percentage 58% and the male was 42%, they have thickening leaflets mitral valve.
The study found that the mean and standard deviation of measurement for males and females was found to be
Normal anterior mitral valve leaflets thickness (2.3 ±.13), abnormal anterior mitral valve leaflets thickness (4.3 ± .35), normal posterior mitral valve leaflets thickness (2.5 ± .13), abnormal posterior mitral valve leaflets thickness (4.6 ± .30).
The study found that there was good relationship between normal and abnormal mitral valve leaflets thickness in Sudanese population. Also the study found that correlation between anterior and posterior leaflets thickness. For leaflets thickening, leaflets motion, leaflets calcification, subvalvular thickening the study showed that there was direct correlation between them.
Regarding the results and comparing with other population it should be considered that the Sudanese findings are greater.
Regarding the results the researcher has come out with the following recommendations:
• The study recommended routine evaluation of mitral leaflets thickness in Sudanese population.
• The study recommended evaluates the same study in different component of mitral apparatus.
• The study recommended performs of several different measurement of mitral valve.
• The study recommended more research to be done with increased duration and sample volume for accurate results.
• Further study should be done for valvular disease with different
