Minimally invasive excision of a mitral valve papillary fibroelastoma, initially suspected as a myxoma, resulted in an uneventful postoperative course with preserved mitral valve function.

Highlights the diagnostic challenge of differentiating papillary fibroelastomas from myxomas intraoperatively and demonstrates successful minimally invasive resection with valve preservation.
Papillary fibroelastomas typically arise from the cardiac valves, whereas cardiac myxomas rarely originate from the valves. Distinguishing these tumors intraoperatively can be challenging. An 81-year-old man was referred for evaluation of an incidental cardiac mass. Transesophageal echocardiography revealed a mobile 10-mm mass attached to the P1 segment of the posterior mitral leaflet. Minimally invasive cardiac surgery via a right mini-thoracotomy allowed satisfactory exposure of the mitral valve. Intraoperative findings and frozen section analysis suggested a myxoma, prompting excision with a margin that included the tumor attachment. However, the final histopathological examination revealed papillary fibroelastoma. The postoperative course was uneventful, and the mitral valve function was preserved. Papillary fibroelastomas and myxomas can be difficult to differentiate intraoperatively. Surgical decision-making should balance adequate tumor resection with preserved valve function when a diagnosis is uncertain.
Inoue et al. (Sun,) conducted a case report in Papillary fibroelastoma of the mitral valve (n=1). Minimally invasive cardiac surgery via right mini-thoracotomy was evaluated on Postoperative course and mitral valve function. Minimally invasive excision of a mitral valve papillary fibroelastoma, initially suspected as a myxoma, resulted in an uneventful postoperative course with preserved mitral valve function.
