摘要

二尖瓣雙開口疾病是一種少見之先天性異常病變。主要特徵為具備二個二尖瓣膜開 口，每個開口各自擁有獨立之腱索及乳突肌.。有些患者會合併其他之心臟異常細心內墊 缺損、主動脈狹縮等,有些則甚至造成二尖瓣狹窄病變。在此提出一例以心導管氣球瓣膜擴張術、治療此一先天性異常合併二尖瓣狹窄成功案例，並首例輔以立體超音波診斷確認此一病變。(中台灣醫誌2002;7:59-64 )

We report a rare case of stenotic double-orifice mitral valve of incomplete bridge-type in a 40 year-old female. Transthoracic two-dimensional echocardiography revealed a double-orifice . mitral valve at the leaflet level, with anterolateral and posteromedial orifices which measured 0.6 and 1.1 cm2 by planimetry, respectively. Color Doppler examination showed separate diastolic flows and trivial regurgitation through each orifice. The fibrous bridge tissue between the leaflets was successfully split using percutaneous Inoue-balloon valvuloplasty with stepwise dilations applied only to the posteromedial orifice. The mitral valve area after the procedure measured 3.0 cm2, Transesophageal echocardiograms with three-dimensional reconstruction also confirmed the presence of a double-orifice mitral valve before and an enlarged single mitral orifice after the valvuloplasty( Mid Taiwan J Med 2002;7:59-64)
