Key result
Recurrent aspiration was associated with the first reported case of isolated, recurrent right ventricular Takotsubo cardiomyopathy.
Case Report (n=1)
This report documents the first known case of isolated, recurrent right ventricular Takotsubo cardiomyopathy, expanding the known phenotypic variants of the condition.

May warrant RV Takotsubo consideration in recurrent aspiration; extends phenotypic variants but remains hypothesis-generating.
Takotsubo cardiomyopathy is described as transient hypokinesis of the apical and mid-segments of the left ventricle with hypercontractile basal segments triggered by emotional or physical stress. Variants with basal hypokinesis and apical hyperkinesis have been described, as well as simultaneous involvement of the right ventricle (RV). Proposed mechanisms include myocardial "stunning" due to excessive catecholamine release. The echocardiographic presentation of Takotsubo cardiomyopathy may be related to differences in regional sympathetic innervation and catecholamine receptor density in the myocardium in the setting of high levels of circulating catecholamines. We describe the first case of isolated, recurrent RV Takotsubo cardiomyopathy reported in the literature.

Chandorkar et al. (2014) conducted a case report in Recurrent Right Ventricular Takotsubo Cardiomyopathy (n=1). Recurrent aspiration was evaluated. Recurrent aspiration was associated with the first reported case of isolated, recurrent right ventricular Takotsubo cardiomyopathy.
