Refractory and fatal hemodynamic depression remarkably occurred eight hours after left carotid artery stenting in a 62-year-old male who had no hemodynamic instability till then; possible contributory factors were pre-existing moderate left ventricular systolic dysfunction and new-onset complete heart block caused by vasopressor-induced sympathetic stimulation in the presence of covert distal conduction system disease.
一名62岁男性在左颈动脉支架置入术后8小时,显著出现难治性和致命性血流动力学抑制,在此之前他并无血流动力学不稳定的情况;可能的促成因素包括既往存在的中度左心室收缩功能障碍,以及在隐匿性远端传导系统疾病存在的情况下,血管升压药诱发的交感神经刺激导致的新发完全性心脏传导阻滞。
