When divided by unified atomic mass units or daltons to form a pure numeric ratio, the atomic mass of an atom becomes a dimensionless value called the relative isotopic mass (see section below). Thus, the atomic mass of a carbon-12 atom is 12 u or 12 daltons (Da), but the relative isotopic mass of a carbon-12 atom is simply 12.
Most people who have mitral valve prolapse (MVP) donât need treatment because they donât have symptoms and complications. Even people who do have symptoms may not need treatment. The presence of symptoms doesnât always mean that the backflow of blood through the valve is significant. People who have MVP and troublesome mitral valve backflow may be treated with medicines, surgery, or both. The goals of treating MVP include:
Mitral valve prolapse is a fairly common medical problem that is the focus of some controversy and even confusion among both physicians and those who suffer from it.There is at the same time less to it and more to it than at first appears.Mitral valve prolapse is named for a heart valve and is usually first diagnosed as a faint heart âclickâ or murmur, though it isnât a form of âheart diseaseâ in any conventional sense.here is at the same time less to it and more to it than at first appears.
