Abstract

Papillary fibroelastoma (PFE) is a benign tumor that arises mostly from left-sided valves. PFE can cause stroke, and surgical resection may be needed. Lambl's excrescence (LE) is a filiform valvular lesion and is considered a possible cause of stroke. A 79-year-old man with light-headedness and left-sided hemiparesis was diagnosed with stroke. Transesophageal echocardiography (TEE) revealed a round-shaped mobile mass in the left ventricular outflow tract (LVOT), which was considered the cause of the stroke. Surgical resection was performed transaortically, and during surgery, a mass was incidentally detected on the noncoronary cusp (NCC), which was also resected followed by aortic valve replacement. Pathology confirmed that the mass in the LVOT was a PFE and that the filiform mass on the NCC was LE. We herein report a rare case of PFE in the LVOT and coexisting LE on the NCC. A careful examination via TEE helps to identify other possible causes of stroke hidden behind the obvious cause.

乳头状纤维母细胞瘤与左心兰布尔赘生物并存病例,偶尔伴有严重中风。
乳头状纤维母细胞瘤(PFE)是一种良性肿瘤,多发于左侧瓣膜。PFE可导致中风,可能需要手术切除。Lambl's excrescence(LE)是一种丝状瓣膜病变,被认为可能导致中风。一名 79 岁的男性因头重脚轻和左侧偏瘫被诊断为中风。经食道超声心动图(TEE)显示,左室流出道(LVOT)内有一个圆形移动肿块,这被认为是中风的原因。在手术过程中,意外发现非冠状动脉尖(NCC)上有一个肿块,也进行了切除,随后进行了主动脉瓣置换术。病理证实 LVOT 中的肿块是 PFE,而 NCC 上的丝状肿块是 LE。我们在此报告一例罕见的 LVOT 内 PFE 和 NCC 上 LE 并存的病例。通过 TEE 进行仔细检查有助于识别隐藏在明显病因背后的其他可能的卒中病因。

期刊介绍: Authors of research articles should disclose at the time of submission any financial arrangement they may have with a company whose product figures prominently in the submitted manuscript or with a company making a competing product. Such information will be held in confidence while the paper is under review and will not influence the editorial decision, but if the article is accepted for publication, the editors will usually discuss with the authors the manner in which such information is to be communicated to the reader.
