二尖瓣脱垂(MVP)综合征在18世纪己被描述,曾命名为“神经性心悸”、“功能性心脏病”、“易激惹心脏”及“Dacosta”综合征等。直至本世纪60年代中期该综合征方为人们所重视。原发性MVP系指瓣叶、瓣环和腱索的结缔组织异常所造成的症候群。超声心动图(UCG)、心血管造影或病理检查时,可见二尖瓣叶子心脏收缩期突向左房。体检时常可听到喀喇音和/或收缩期杂音。近年来有人对本综合征的存在提出疑意。
Mitral valve prolapse (MVP) syndrome has been described in the 18th century and was named “neuropathic palpitations”, “functional heart disease”, “irritable heart” and “Dacosta” syndrome. Until the mid-60s of this century, the syndrome is valued by people. Primary MVP is the syndrome caused by the abnormal connective tissue of the valve leaflets, annulus and chordae. Echocardiography (UCG), cardiovascular angiography or pathological examination showed mitral valve leaflets systolic sudden left atrium. Physical examination can often hear the click sound and / or systolic murmur. In recent years, some people have raised the suspicion of the existence of this syndrome.
