Analysis of ultrasonic cardiogram image of mitral valve prolapse and ruptured mitral chordae tendineae in patients over 45 years of age

Objective:To explore characteristics of ultrasonic cardiogram in patients with mitral valve prolapse and ruptured mitral chordae tendineae.Methods:The cardiac structures and functions of fifty-four patients over 45 years of age who suffered from mitral valve prolapse and ruptured mitral chordae tendineae were evaluated with ultrasonic cardiogram.Results:There was no gender-related difference in the mitral valve prolapse group.And there was no difference in the incidence of prolapse between anterior mitral valve leaflet and posterior mitral valve leaflet.Moderate mitral regurgitation(73.1%) was significantly more common in this group.The ruptured mitral chordae tendineae was more common in men(67.9%) than in women(32.1%).And the ruptured mitral chordae tendineae was more common in the posterior mitral valve leaflet(60.7%).Moreover,moderate to severe mitral regurgitation was significantly more common(92.9%).The changes of the cardiac structures in the mitral valve prolapse group were more than those in the ruptured mitral chordae tendineae group.Conclusion:The features of ultrasonic cardiogram are obvious in patients over 45 years of age who suffer from mitral valve prolapse and ruptured mitral chordae tendineae.
