Iatrogenic pneumohemomediastinum mimicking cardiac tamponade: a complication of catheter ablation procedure

Pacing Clin Electrophysiol. 1997 Jan;20(1 Pt 1):138-9. doi: 10.1111/j.1540-8159.1997.tb04827.x.

Abstract

We describe a patient who developed cardiac tamponade during electrophysiological mapping aimed at ablating an atrioventricular accessory pathway. Transesophageal echocardiography showed compression of the left pulmonary veins due to pneumohemomediastinum secondary to left subclavian vein cannulation.
