Right ventricular outflow tract mass - an unusual cause of syncope

Abstract

Primary intracardiac tumours are a rare entity, having an incidence of 0.001 to 0.03 only. We present a case of recurrent syncope in a 42 year old male, caused by a myxoma in the RVOT (Right ventricular outflow tract), which is a highly unusual site for the tumour. After thorough evaluation, surgical excision of the RVOT mass was done and histopathological examination confirmed the diagnosis. The patient became asymptomatic after the surgery and Echocardiography also showed normalisation of the gradient across the RVOT after the excision of the mass. A high degree of suspicion is necessary to identify primary intracardiac tumours as the presentation is often misleading and the condition mimics other general systemic illness. There is prompt relief of symptoms for such patients once the mass is excised, hence calling for increased vigil while screening for primary tumours in patients with atypical symptomatology.
