Key result
Transient complete AV block in midventricular Takotsubo cardiomyopathy resolves completely without a permanent pacemaker.
Why the study?
Midventricular Takotsubo cardiomyopathy complicated by transient complete atrioventricular block is a rare clinical presentation requiring detailed characterization.
Case Report (n=1)
No
Midventricular Takotsubo cardiomyopathy can be complicated by transient complete atrioventricular block that may resolve completely, avoiding the need for permanent pacemaker implantation.
Supports expectant management of transient AV block in Takotsubo cardiomyopathy; leaves open whether permanent pacing is ever indicated.
A 63-year-old woman had mistakenly drunk detergent stored in a plastic bottle and was transported to our hospital via ambulance due to unconsciousness. In the emergency room, the monitoring electrocardiogram showed complete atrioventricular block and temporary pacing was thus started. Left ventriculography indicated midventricular Takotsubo cardiomyopathy, although coronary angiograms showed a normal appearance. The atrioventricular block was transient, and the reduced left ventricular wall motion gradually recovered. An electrophysiological study performed before discharge showed no abnormalities in the atrioventricular conduction system. In conclusion, we experienced a case of mid-ventricular Takotsubo cardiomyopathy complicated by transient complete atrioventricular block.

Sugiura et al. (2013) conducted a case report in Midventricular Takotsubo cardiomyopathy (n=1). Severe emotional stress (mistakenly drinking detergent) was evaluated on Clinical recovery. A 63-year-old woman developed midventricular Takotsubo cardiomyopathy complicated by transient complete atrioventricular block following severe emotional stress, which resolved completely without the need for a permanent pacemaker.
