Abstract

Myxomas are rare cardiac neoplasms and may present as single or multiple tumors. Only a few cases of single biatrial myxomas have been reported. We report a very rare case of this condition in a middle-aged woman, presenting with exertional dyspnea and cough. The patient had a resting tachycardia of 105 beats per minute, and cardiac auscultation discovered a mid-diastolic murmur across the mitral valve, followed by a tumor plop focused on the apex and elevated levels of C-reactive protein (1+) and creatine phosphokinase in lab data. The diagnosis was made via transesophageal and transthoracic echocardiographic examinations, showing the tumor extension through a patent foramen ovale (PFO). The operation was undertaken, the myxoma was excised, and the PFO was repaired. She was discharged with no further complications. Although myxomas are rare, considering this condition before surgery is significant. The involvement of both atria via a PFO is possible.
