• Reversible outflow tract obstruction is a rare complication of myocardial infarction. • Immediate bedside echocardiogram can help recognize this complication. • Sigmoid-shaped septum and narrow aortoseptal angle are likely anatomic contributors. • Tachycardia, hypertension, and basal hypercontractility are hemodynamic factors. • Early beta-blockers and revascularization can reverse this complication.
• 可逆性流出道梗阻是心肌梗死的一种罕见并发症。
• 床边即时超声心动图有助于识别这一并发症。
• 乙状结肠形室间隔和狭窄的主动脉-室间隔角可能是解剖学上的促成因素。
• 心动过速、高血压和基底节高收缩性是血流动力学因素。
• 早期使用β受体阻滞剂和血运重建可逆转这一并发症。
