We describe a patient with severe aortic stenosis who underwent CoreValve (Medtronic) implantation and presented several days later with a tachyarrhythmic episode. The electrocardiographic features of the arrhythmia were compatible with left-ventricular outflow tract ventricular-tachycardia. The life-threatening event was not associated with ischemia or an electrolyte disorder and was not drug-induced. A probable cause was the irritation of the myocardium by the prosthetic valve. Clinicians should be aware that the presence of anatomical parameters that increases the risk for myocardial injury and the need for pacemaker implantation might indicate an increased risk of a tachyarrhythmic episode.
我们描述了一位患有严重主动脉瓣狭窄的患者,他接受了 CoreValve(美敦力)植入术,几天后出现了心动过速性心律失常。心律失常的心电图特征与左心室流出道室性心动过速一致。危及生命的事件与缺血或电解质紊乱无关,也不是药物引起的。可能的原因是假体瓣膜对心肌的刺激。临床医生应该意识到,存在增加心肌损伤风险和需要植入起搏器的解剖参数可能表明心动过速性心律失常发作的风险增加。
