A free floating ball thrombus in left atrium is very rare, only 2 cases that develop ball thrombus after mitral valve replacement (MVR) have been reported. This case was a 55-year-old female who underwent MVR and tricuspid annuloplasty (TAP) in 1978. After 16 years, she developed replaced mitral valve stenosis due to pannus formation and tricuspid regurgitation (TR), with a free floating ball thrombus in the giant left atrium. A ball thrombus was taken out, and Re-MVR and tricuspid valve replacement (TVR) was carried out. Post operative course was uneventful. Because a free floating ball thrombus easily causes "Hole-in-one" sudden death, early surgical treatment must be considered.
左心房内的游离球形血栓非常罕见，仅有2例二尖瓣置换术（MVR）后发生球形血栓的病例报道。该病例为一名55岁女性，于1978年接受了二尖瓣置换术和三尖瓣环成形术（TAP）。16年后，她因血管翳形成出现人工二尖瓣狭窄和三尖瓣反流（TR），巨大的左心房内有一个游离球形血栓。取出球形血栓后，进行了再次二尖瓣置换术和三尖瓣置换术（TVR）。术后过程顺利。由于游离球形血栓容易导致“一击毙命”式的猝死，必须考虑早期手术治疗。
