There is good opacification of the pulmonary arterial tree with no evidence of pulmonary embolus. There is no evidence of right heart strain. There is a polypoidal soft tissue filling defect within the anterior aspect of the left atrium, apparently arising from the intra-atrial septum via a pedicle, in keeping with an atrial myxoma. There is bibasal patchy atelectasis and small bilateral pleural effusions.
