Method: a specially designed hook was introduced into the left atrium from the left superior pulmonary vein, partial chordae tendines of mitral valve were transected to produce moderate mitral regurgitation. 方法:经实验犬左上肺静脉置入特制金属钩,钩断部分二尖瓣腱索,产生中度二尖瓣返流。
Results: CT images showed synovial proliferation of bursa carpi ulnaris, the tendines were disarranged. 结果:CT显示腕尺侧滑液囊滑膜增生,滑液囊增宽、增厚、延长,其内肌腱排列次序紊乱、分散、推移而无增粗改变。
