MVP may lead to excessive
stress on the papillary muscles, which,
in turn, leads to dysfunction and
ischemia of the papillary muscles and
the subjacent ventricular myocardium. Rupture of chordae tendineae
and progressive mitral annular dilation and calcification contribute to valvular
regurgitation, which then places more stress on the diseased mitral
valve apparatus, thereby creating a vicious circle.
However the clinical course is most often benign and most patients are asymptomatic and remain so for their entire lives.Initial MR severity is the primary predictors of progression.In your case LVEF (70%) is excellent and long-term course is likely to be benign .
Beta blockers sometimes relieve
chest pain and control palpitations.
