Why the study?
Does mitral valve morphology correlate with the severity of mitral regurgitation and occurrence of ruptured chordae tendineae in patients with mitral valve prolapse?
Population
67 subjects, comprising 37 patients with mitral valve prolapse (MVP) and 30 control subjects.
Design
Case-control

May support morphology-guided risk stratification in MVP; hypothesis-generating and requires prospective validation before practice change.
Does mitral valve morphology correlate with the severity of mitral regurgitation and occurrence of ruptured chordae tendineae in patients with mitral valve prolapse?
Mitral valve leaflet thickness, length, and annular diameter are proportionally redundant in MVP and closely relate to the occurrence of ruptured chordae tendineae or severe mitral regurgitation.
Sonoda et al. (2008) studied this question.
