[Hypotension after catheter ablation].

A 80-year-old female patient with symptomatic atrial tachycardia develops cold sweat and hypotension in the recovery room after pulmonary vein isolation. The procedure included an anterior line and an endo- and epicardial mitral isthmus line. Echocardiography excluded a hemodynamically relevant pericardial effusion. The patient's symptoms deteriorated over time. A rare cause was found.
