In addition, the additional somatic disorders are reported in a condition typically described as asymptomatic. Antibiotic dosages vary according to the patients ability to tolerate a particular regimen. The American Heart Association recommends 3.0 grams of amoxicillin orally one hour before the procedure and then 1.5 grams six hours after the initial dose. Depending upon the severity of the MVP, the treatment may be more powerful than an occasional dosing of antibiotics. For severe MVP, replacement of the valve may be in order.
Mechanical valves have the advantage of durability but the disadvantage of causing blood clots.
Biological tissue valves negate the need for anti-coagulant medication but are less durable and more likely to be rejected by the immune system. There is little likelihood that MVP would cause death. Although the statistics compare 1990 with 1993, it is clear that the most commonly diagnosed valvular disorder causes relatively few deaths and hospitalizations. For most people, treatment of an MVP consists of nothing more than the previously recommended administration of antibiotics and occasional rest and stress management. For others, surgical intervention is necessary.
