Right atrial myxoma presenting as syncope due to pulmonary embolism in a previously asymptomatic patient
Abstract:
Tumours of the heart are rare, and in the vast majority of cases are myxomas that have a benign profile. According to their location, their clinical manifestations differ but there are cases that are completely asymptomatic [M. Yuce, S. Dagdelen, M. Ergelen, N. Eren, N. Caglar, A huge obstructive myxoma located in the right heart without causing any symptom. Int J Cardiol 2007;114:405-406.], found only post-mortem. Herein we describe the case of a 45-year-old female patient previously asymptomatic who presented with syncope due to a large right atrial myxoma with extracardiac localization as embolic phenomenon in the pulmonary artery tree.
