Title

Takotsubo Cardiomyopathy Presenting with Sinoatrial Disease: A Rare Presentation

Publication/Presentation Date

Abstract

Takotsubo cardiomyopathy (TCM), or apical ballooning syndrome, is a distinct nonischemic cardiomyopathy mimicking acute coronary syndrome. A 76-year-old female presented with ST elevation in the inferior lead and a troponin level of 0.81 ng/dL. An immediate coronary angiography showed non-obstructive coronary artery disease. A subsequent ventriculogram and echocardiogram showed anteroapical and distal inferior wall hypokinesis suggestive of TCM. Despite therapy with beta blocker, she was observed to have two significant sinus pauses, one eight-second, and a second 29-second pause. An urgent transvenous pacemaker was put in place and later followed by a permanent pacemaker. The patient was discharged on carvedilol and losartan. Although other arrhythmias such as complete heart block, torsades, and ventricular arrhythmias have been commonly reported, the association of TCM with recurrent sinus arrest has rarely been reported in the literature. The occurrence observed in this case implies that patients with TCM should be monitored closely for arrhythmias, and, if such a condition is identified, planning for permanent pacemaker implantation should be started early enough to avoid recurrent life-threatening episodes.
