Lipoma of the interventricular septum involving the tricuspid valve is a rare entity. A 50-year-old woman presented with exertional dyspnea. She was found to have a large right interventricular septal mass in the initial transthoracic echocardiography. This mass was further investigated by transesophageal echocardiography, cardiac gated CT, and cardiac magnetic resonance imaging. It was found to be lipomatous and embedded into the septal leaflet of the tricuspid valve. The diagnosis was confirmed by biopsy. Surgical exploration revealed that the mass was deeply embedded in the interventricular septum and septal leaflet of the tricuspid valve. The mass was resected along with sections of the interventricular septum and tricuspid valve. She underwent bioprosthetic tricuspid valve placement and patch reconstruction of the interventricular septum. We also searched case reports from MEDLINE and studied pathological and epidemiological characteristics of the published cases of cardiac masses in the past year. Cardiac lipoma although a benign tumor can cause serious hemodynamic complications. Initial transthoracic echocardiography followed by multimodality imaging is the cornerstone of the diagnosis.
间隔内室瘤累及三尖瓣是一种罕见的实体。一位 50 岁的女性因劳累性呼吸困难就诊。最初的经胸超声心动图发现她有一个大的右室间隔肿块。经食管超声心动图、心脏门控 CT 和心脏磁共振成像进一步检查发现该肿块为脂肪瘤，并嵌入三尖瓣的隔瓣。通过活检确诊。手术探查发现肿块深深地嵌入室间隔和三尖瓣的隔瓣。切除了肿块及部分室间隔和三尖瓣。她接受了生物瓣三尖瓣置换和室间隔补丁重建。我们还在 MEDLINE 上搜索了病例报告，并研究了过去一年发表的心脏肿块病例的病理和流行病学特征。心脏脂肪瘤虽然是良性肿瘤，但可引起严重的血流动力学并发症。初始经胸超声心动图，然后是多模态成像，是诊断的基石。
