Thank you for your question, yes leaking mitral valve carries formidable risk for endocarditis. So endocarditis prophylaxis is needed in such cases.
Thank you for your reply, ..In the new guidelines, the Committee noted that mitral valve prolapse (MVP) is the most common underlying condition that predisposes to the acquisition of IE in the western world...
These above wordings are from following reference.
Thank you for your reply, Mitral valve leak is still the major cause of infective endocarditis.
Thank you for your reply, sorry i was out of city for few days.. i can understand your confusion. MVP is the major cause still the incidence of IE with MVP is low..
This means that if there are 100 cases of IE or infective endocarditis majority are secondary to MVP. e.g 30 cases out of 100 are due to MVP but you can see around 7% of population in many countries have some degree of MVP so this makes it million of cases of MVP. Incidence means cases occurring in a population. So it means that MVP is most common cause but still incidence is low. I hope this helps.
