Abstract
Right atrial diverticulum is a very rare anomaly. It is an outpouching arising from the right atrial free wall. Clinical presentations vary widely but some cases are associated with supraventricular tachycardia and atrial flutter/fibrillation. The incidence/prevalence of this anomaly is not available because only a few cases have been reported. We report a 38-year-old female patient who presented to the Heart Clinic, Tehran, Iran in 2019 with a history of dyspnea and chest pain. Electrocardiography revealed left bundle branch block. Following a magnetic resonance imaging study, the patient was diagnosed with a right atrial diverticulum. She underwent surgical resection of the diverticulum. The post-operative course was uneventful and no recurrence of the arrhythmia was detected during the six months of follow-up. To the best of the authors’ knowledge, this combination has not been described in the literature.

Summary
A 38-year-old female patient presented to the Heart Clinic, Tehran, Iran in 2019 with a history of palpitation, dyspnoea on exertion and recurrent chest pain accompanied by three episodes of syncope that occurred two years prior to presentation. She received imipramine for depression but the symptoms did not improve. Transthoracic echocardiography showed an echolucent space around the RA approximately 2 × 3 cm in size that was connected to the RA [Figure 2]. Cardiac magnetic resonance imaging (MRI) showed a 25.2 × 16.5 × 35 mm pouch in the inferior wall of the RA [Figure 3].
