Primary neoplasms of the cardiac valves are extremely rare. However, papillary fibroelastoma is the third most common primary tumor of the heart [Ann Thorac Surg 52 (1991) 1127]. These tumors can be found anywhere in the heart, but most commonly involve the cardiac valves [Ann Thorac Surg 52 (1991) 1127; McAllister HA, Fenoglio JJ. Tumors of the cardiovascular system. In: Atlas of tumor pathology, 2nd series, vols. 1-3. Washington (DC): Armed Forces Institute of Pathology; 1978. p. 20-5]. Most papillary fibroelastomas do not cause symptoms and are usually incidental findings by routine echocardiography or at autopsy. However, early diagnosis of this condition is important, since it represents a surgically correctable cause of systemic emboli, stroke, myocardial infarction, and sudden cardiac death [Ann Thorac Surg 52 (1991) 1127; Ann Thorac Surg 68 (1999) 1881; J Am Soc Echocardiogr 9 (1996) 353; Tex Heart Inst J 22 (1995) 327; Tex Heart Inst J 26 (1999) 298]. The echocardiographic findings should be confirmed by histology, since the clinical differential diagnosis includes myxoma, vegetation, thrombi, lipoma, and pseudopapillary fibroelastoma [Tex Heart Inst J 26 (1999) 298; J Am Soc Echocardiogr 11 (1998) 92; J Natl Med Assoc 87 (1995) 68]. Review of the literature reveals that multiple papillary fibroelastomas are extremely rare [Am Heart J 125 (1993) 1443; J Am Soc Echocardiogr 7 (1994) 315; Ann Thorac Surg 48 (1989) 119]. Li Manduri et al. [J Am Soc Echocardiogr 7 (1994) 315] reported multiple masses on the tricuspid valve, the larger of which was 1 cm in diameter. De Virgilio et al. [Ann Thorac Surg 48 (1989) 119] reported a case of multiple 1-cm papillary fibroelastomas located on mitral valve, left ventricular outflow tract, and along septum. We report an unusual case of multiple papillary fibroelastomas in a woman, who initially was admitted because of a shortness of breath and recent cerebrovascular accident.
心脏瓣膜原发性肿瘤极为罕见。然而,乳头状纤维弹性瘤是心脏第三常见的原发性肿瘤[《胸外科年鉴》52(1991)1127]。这些肿瘤可在心脏的任何部位发现,但最常累及心脏瓣膜[《胸外科年鉴》52(1991)1127;麦卡利斯特HA,费诺利奥JJ。心血管系统肿瘤。见:《肿瘤病理学图谱》,第2版,第1 - 3卷。华盛顿(特区):武装部队病理研究所;1978年。第20 - 5页]。大多数乳头状纤维弹性瘤不引起症状,通常是在常规超声心动图检查或尸检时偶然发现。然而,这种疾病的早期诊断很重要,因为它是系统性栓塞、中风、心肌梗死和心源性猝死的可手术纠正病因[《胸外科年鉴》52(1991)1127;《胸外科年鉴》68(1999)1881;《美国超声心动图学会杂志》9(1996)353;《德克萨斯心脏研究所杂志》22(1995)327;《德克萨斯心脏研究所杂志》26(1999)298]。超声心动图检查结果应由组织学证实,因为临床鉴别诊断包括黏液瘤、赘生物、血栓、脂肪瘤和假乳头状纤维弹性瘤[《德克萨斯心脏研究所杂志》26(1999)298;《美国超声心动图学会杂志》11(1998)92;《美国国家医学协会杂志》87(1995)68]。文献回顾显示,多发性乳头状纤维弹性瘤极为罕见[《美国心脏杂志》125(1993)1443;《美国超声心动图学会杂志》7(1994)315;《胸外科年鉴》48(1989)119]。李和曼杜里等人[《美国超声心动图学会杂志》7(1994)315]报告了三尖瓣上有多个肿块,其中较大的直径为1厘米。德维尔吉洛等人[《胸外科年鉴》48(1989)119]报告了一例多发性1厘米乳头状纤维弹性瘤病例,位于二尖瓣、左心室流出道和室间隔。我们报告了一例不寻常的多发性乳头状纤维弹性瘤病例,患者为一名女性,最初因呼吸急促和近期脑血管意外入院。
