LV Diverticulum with Concurrent Takotsubo Cardiomyopathy

Abstract

Introduction Left ventricular diverticulum was first described in 1838 and is thought to occur in 0.4% of the population [1,2]. Left ventricular diverticulum is challenging to diagnose due to the asymptomatic nature and lack of consistent ways to describe the outpouching, however it is known that it contains all layers of the heart [3-5]. Previous authors have tried to classify based on using the size of diverticulum compared to the size of the left ventricle [4]. Diverticulum can be classified as either muscular or fibrous and they display contractile features consistent with the remaining heart [3,4]. As much as 30% of left diverticulum cases are not associated with congenital abnormalities and can present with chest pain [3]. Echocardiography and angiography can be used for diagnosis and surgical resection are typically the treatment of choice before complications such as endocarditis, arrhythmia, heart failure, and tamponade occur [1,6].
