A 53 year old man with a history of rheumatic mitral stenosis was admitted to hospital because of recurrent fainting spells. Auscultation showed a variable diastolic rumbling murmur. Simultaneous echo- and phonocardiograms demonstrated a floating left atrial thrombus; when this passed into the left ventricular inflow tract and obstructed the mitral valve orifice the diastolic murmur disappeared.
一名有风湿性二尖瓣狭窄病史的53岁男性因反复晕厥发作入院。听诊显示有变化的舒张期隆隆样杂音。同步超声心动图和心音图显示左心房有一漂浮血栓；当该血栓进入左心室流入道并阻塞二尖瓣口时，舒张期杂音消失。
