RESUMO
Cardiac fibromas are the second most common primary cardiac tumors in childhood. They only rarely present in adults. They are mainly located in the free wall of the ventricles and attached to the interventricular septum. Despite their benign pathology, fibromas in some locations can cause significant complications. This video tutorial illustrates the resection of a septo-apical cardiac fibroma in an asymptomatic 26-year-old woman, diagnosed with transthoracic echocardiography and cardiac magnetic resonance imaging after an abnormal ECG on an occupational medical examination. Surgery was performed through a median sternotomy using cardiopulmonary bypass. A nodular intramyocardial mass was found at the left ventricular apex and resection was carried out. After removing the fibroma, a defect was found at the apex affecting both ventricles. The defects were closed using a direct suture of 4-0 polypropylene "U" stitches reinforced with a Teflon patch to exclude the ventricular cavity. Pathology confirmed the diagnosis of benign cardiac fibroma with tumor-free surgical margins. The patient recovered uneventfully and was discharged on postoperative day 5. The outpatient follow-up cMRI 10 months after surgery showed no signs of tumor recurrence and normal biventricular function.
