Abstract

Background: Papillary fibroelastoma is a rare, benign cardiac tumor that typically originates from the cardiac valves, with papillary muscle involvement being extremely rare. However, optimal management of papillary fibroelastoma remains variable.

Case presentation: A 79-year-old female with multiple comorbidities, including Parkinson's syndrome, diabetes, and frailty, was referred to our hospital because an incidental left ventricular mass was detected during a preoperative evaluation for knee osteoarthritis. Echocardiography and computed tomography revealed a mobile, 17-mm mass in the left ventricle, possibly attached to the posterior papillary muscle. The morphological findings were suspicious for papillary fibroelastoma. The tumor was surgically resected from the papillary muscle using a three-dimensional thoracoscopy-assisted right limited-thoracotomy approach. Histopathological analysis confirmed the diagnosis of papillary fibroelastoma. Postoperatively, the patient was discharged without complications, and no recurrence was observed at the 1-year follow-up.

Conclusion: This case demonstrates the feasibility and efficacy of minimally invasive video-assisted right thoracotomy for the resection of a papillary fibroelastoma originating from the papillary muscle.

微创视频辅助切除起源于左心室乳头状肌的乳头状纤维弹性瘤1例。
背景:乳头状纤维弹性瘤是一种罕见的良性心脏肿瘤,通常起源于心脏瓣膜,并累及乳头状肌极为罕见。然而,乳头状纤维弹性瘤的最佳治疗方法仍然是可变的。病例介绍:一名79岁女性,患有多种合并症,包括帕金森综合征、糖尿病和虚弱,由于在术前评估膝关节骨关节炎时发现偶然的左心室肿块而被转介到我院。超声心动图和计算机断层扫描显示左心室有一个可移动的17毫米肿块,可能与后乳头肌相连。形态学表现怀疑为乳头状纤维弹性瘤。采用三维胸腔镜辅助右有限开胸入路从乳头肌切除肿瘤。组织病理学分析证实了乳头状纤维弹性瘤的诊断。术后出院,无并发症,随访1年无复发。结论:本病例证明了视频辅助下微创右开胸切除起源于乳头状肌的乳头状纤维弹性瘤的可行性和有效性。
