Prevalence of bicuspid aortic valve and mitral valve prolapse in a healthy Saudi population and the clinical implications of their association.

In this study, 103 Saudi males and 172 Saudi females were referred for medical check-up for employment purposes and/or as undergraduate students. Clinical evaluation of all participants included full cardiovascular examination, with the following investigations being performed: ECG, chest x-ray, and cross-sectional echocardiography. Bicuspid aortic valve was detected in three males and in four females, for a total percentage of 2.5%. Isolated mitral valve prolapse was detected in seven males (6.7%) and six females (3.5%). Association with mitral valve prolapse was reported in five males and seven females, with a total percentage of 4.3%. This association seems to have important etiological, medical and surgical implications.
