[Recurrent cardiac myxoma that developed rapidly in a short period].
A 55-year-old woman, who had undergone extirpation of left atrial myxoma 3-years before, was admitted to our hospital with dyspnea. Chest computed tomography revealed a low density mass in the left atrium (LA) with a diameter of 54 mm. Transthoracic echocardiography showed that the mass was attached to the left atrial septal wall and had a pendulum-like movement. We urgently performed an operation for recurrent left atrial myxoma. Through atrial transseptal approach, a huge myxomatus tumor was observed in the LA. The stalk was on the endocardium at the cranial side of the previous autologous pericardial patch. The tumor was completely excised along with the patch. We repaired the disrupted endocardium and performed Dacron patch repair of the atrial septal defect. The patient recovered uneventfully and was discharged 14 days after surgery. The excised tumor was found to be myxoma on pathological examination similar to the previous tumor. We report a case of recurrent left atrial myxoma with rapid growth in a short time period.
