GONZALEZ L., Roberto et al. Embolic stroke secondary to a mitral valve fibroelastoma. Case report. Rev. méd. Chile [online]. 2019, vol.147, n.2, pp.243-246. ISSN 0034-9887.

Embolic stroke secondary to cardiac tumors is uncommon. However, 25-30% of cardiac tumors may cause systemic emboli. We report a 29-year-old male consulting for a sudden episode of aphasia and right hemiparesis, compatible with infarct of the left middle cerebral artery territory. Transthoracic echocardiography reported an ovoid tumor of 8 × 7 × 7 mm in relation to the sub valvular apparatus of the mitral valve. After neurologic stabilization, surgical treatment was performed. Approached by median sternotomy and in cardiopulmonary bypass, the mitral valve was explored. A macroscopic tumor consistent with a papillary fibroelastoma curled in sub valvular chordae was found. It was deployed and resected from its base, while the anterior mitral leaflet was preserved intact. Histopathological examination confirmed the intraoperative macroscopic diagnosis. The patient recovered uneventfully postoperatively and was discharged on the fifth day after surgery. He currently is in functional capacity I without cardiovascular symptoms at five years follow-up.
