LV Diverticulum with Concurrent Takotsubo Cardiomyopathy

Abstract

Takotsubo Cardiomyopathy was first described in 1991 and most often occurs in females due to perceived physical or emotional stress. Takotsubo Cardiomyopathy has an estimated incidence of 100 new cases per million each year and accounts for 2% of all suspected acute coronary syndrome [7]. Diagnosis criteria for takotsubo cardiomyopathy include: no significant history of coronary artery disease, ST elevation and or T wave EKG changes, and absence of pheochromocytoma or myocarditis, and temporary dyskinesis/hypokinesis/akinesis in left ventricle with/without associated apical involvement [8]. Current evidence suggests that post-menopausal women (> 50 years old) are more at risk for takotsubo due to the estrogen deficiency and the noted role of estrogen in reducing the stress-induced damage to the heart. The prevalence of Left Ventricular Diverticulum with 
Takotsubo Cardiomyopathy is unknown, and the pathogenesis is incompletely understood [7]. Here we present a case of Takotsubo 
Cardiomyopathy a newly diagnosed Left Ventricular Diverticulum. To our knowledge, there is only one other reported case in 2008 [9].
