一例68岁女性患者,持续心房颤动射频消融术后1天出现呼吸困难并逐渐加重,胸片提示双肺渗出性病变,N末端-前体脑钠肽明显升高,超声心动图显示左房射血分数(LAEF)下降,左房顿抑明显,急性左心衰竭发生,经过利尿抗心力衰竭治疗后10天,症状缓解,胸片显示双肺渗出吸收,超声心动图显示LAEF恢复。提示:心房颤动射频消融术后要警惕心房顿抑诱发急性左心衰竭的发生。
A 68-year-old woman with persistent dyspnea on day 1 of radiofrequency ablation of atrial fibrillation and chest X-ray showed exudative pulmonary lesions and increased N-terminal pro-brain natriuretic peptide. Echocardiography showed left atria LVEF decreased, left lepton suppressed obviously, acute left heart failure occurred. After diuresis and anti-heart failure treatment ten days, the symptoms were relieved. The chest radiograph showed double lung exudation and absorption, and the echocardiogram showed LAEF recovery. Tip: Atrial fibrillation after radiofrequency ablation should be wary of atrial fibrillation induced acute left heart failure.
