主动脉内球囊反搏在主动脉瓣重度狭窄患者中的应用

Application of intra - aortic balloon counterpulsation in a patient with severe aortic stenosis

主动脉内球囊反搏（IABP）广泛应用在急性心肌梗死（AMI）合并心源性休克、难治性不稳定型心绞痛及血流动力学不稳定的高危冠状动脉介入治疗等患者。然而，目前还没有推荐IABP应用于重度主动脉瓣狭窄（As）患者。我们报道1例重度AS患者发生心脏骤停，复苏后血流动力学障碍，及时植入IABP，迅速逆转了血流动力学恶化，为进一步外科主动脉瓣置换手术提供了安全过渡的保障。

Intraaortic balloon pumping （IABP） has been used widely in the setting of acute myocardial infarction complicated by cardiogenic shock, unstable coronary syndromes, and hemodynamic instability patients undergoing percutaneous coronary intervention （PCI）. However, there currently are no recommendations for utilisation of IABP in patients with critical aortic stenosis （AS）. In this report, we describe the successful implementation of IABP counterpulsation in a patient with cardiac arrest and unstable hemodynamic complicating severe AS. The placement of IABP in this setting is associated with rapid improvement in haemodynamics, and plays a prominent role in bridging the patient to aortic valve replacement surgery.
