A 56-year-old man presented with severe aortic valve disease. Pulsus alternans was recorded in the left ventricle, apparently provoked by catheter placement through a stenotic aortic valve. This case illustrates that studies on left ventricular performance in severe aortic stenosis should be done with a transseptal catheter.
一名56岁男性因严重主动脉瓣疾病前来就诊。在左心室记录到交替脉，显然是由于通过狭窄主动脉瓣放置导管所诱发。该病例表明，对于严重主动脉瓣狭窄患者左心室功能的研究应采用经房间隔导管进行。
