The prevalence of mitral-valve prolapse in an Australian volunteer population was found to be 4%, with no significant difference in symptoms or ECG abnormalities compared to those without prolapse.
MVP appears incidental without excess symptoms or ECG changes; leaves open its prognostic relevance in unselected populations.
The prevalence of mitral-valve prolapse in 200 volunteers (100 men and 100 women) was investigated by means of a combination of clinical, phonocardiographic, and echocardiographic findings. Mitral valve prolapse was documented on M-mode echocardiography in four men and four women, giving an over-all prevalence of 4%. In addition, symptoms and electrocardiographic abnormalities, which are reported to occur more commonly in patients with mitral valve prolapse, occurred with equal frequency in the subjects with mitral valve prolapse and in those without prolapse.
