Although the prevalence of mitral valve prolapse was once thought to be as high as 15
percent in the general population, more recent studies using new echocardiographic
criteria for diagnosis have suggested a prevalence of approximately 2.4 percent.
Clinical futures
•
MVP is more common in females and more common in the age group of 14-30.
•
The clinical course is often benign
•
Most patients are asymptomatic and may remain so for their entire lives.
•
Some patients may manifest with features of Mitral regurgitation
•
Arrhythmias like premature ventricular contractions and ventricular tacycardias may
occur as complications.
•
The mid-systolic click, often accompanied by a late systolic murmur, is the auscultatory
hallmark of mitral valve prolapse.
Management
•
Asymptomatic patients may need only reassurance
•
Symptomatic patients with thickening of mitral valve
•
o
Endocarditis prophylaxis is
o
B- blockers sometimes may relive chest pain
Sever symptoms from secondary MR: surgical treatment may be needed ( mitral valve
repair and or rarely replacement. )

Even though the definitive management for most valvular heart diseases is surgical
intervention to correct the underlying valvular abnormality , in the current Ethiopian
setup, surgical interventions are not affordable and not available in the country. Hence
the general management is treatment of the congestive heart failure state.
•
The onset of symptoms in the developing world occurs at an earlier age because of
repeated attack of recurrent rheumatic fever. Increased left atrial pressure and
decreased cardiac output produce the symptom. Therefore both primary and secondary
preventions are paramount importance to reduce the morbidity and mortality
•
Great progress has been made in improving rates of morbidity and mortality in patients
with valvular heart disease. Successful management of patients with valvular heart
disease requires an evidence-based approach to echocardiography and to surgical
intervention.
