Conclusions: In MVP, myocardial deformation analysis with strain echocardiography
identiﬁed speciﬁc contraction patterns with postsystolic shortening leading to
increased values of PSI and MD, translating the importance of mitral valve–
myocardial interactions in the arrhythmogenesis of severe ventricular arrhythmia.
Strain echocardiography may provide important implications for rhythmic risk
stratiﬁcation in MVP
