Most cases of MVP have which associated lesion?

• A. MR
• B. MS
• C. Aortic stenosis
• D. Tricuspid regurg

Answer: (A)

Mitral valve prolapse typically involves redundant, myxomatous mitral leaflets that billow into the left atrium during systole. This abnormal coaptation often leads to mitral regurgitation because the leaflets fail to close snugly, allowing blood to leak backward. So, in most cases MVP is accompanied by mitral regurgitation, with the severity varying based on prolapse extent and annular involvement. Other valve lesions like mitral stenosis or aortic stenosis aren’t the common associates, and while some left-sided disease can be linked to tricuspid regurgitation, it’s not the predominant associated lesion with MVP. Therefore, mitral regurgitation is the best answer.
