Lung ventilation/perfusion scintigraphy shows the efficacy of anticoagulant therapy and surgical treatment for papillary fibroelastoma originating from the tricuspid valve.

ABSTRACT: Papillary fibroelastoma (PFE) is a cardiac tumor that is mainly found on the heart valve and the endocardium of the atria and ventricles. Symptoms such as stroke and myocardial infarction are usually caused by embolization of either the tumor itself or associated thrombus. PFE is known to originate mainly from the left side of the heart, and these cases are-in principle-candidates for surgical resection. On the other hand, cases in which PFE originates from the right side of the heart are rare and reports are limited; thus, the surgical indication is unclear. We herein report a case of symptomatic PFE originating from the tricuspid valve of the heart. In this case, contrast enhanced computed tomography did not show pulmonary embolism; however, lung perfusion scintigraphy showed multiple perfusion defects. The patient was treated by anticoagulant therapy followed by surgical resection. Thereafter, the symptoms disappeared and the multiple perfusion defects improved on lung perfusion scintigraphy, demonstrating the efficacy of the anticoagulant therapy and surgical resection for PFE in the right side of the heart. .

Nonsurgical management of a tricuspid valvular pedunculated papillary fibroelastoma.

Project description:A 25-year-old woman with a history of kidney transplantation for lupus nephritis was referred for the evaluation and management of a mass incidentally found on echocardiography. An oval and pedunculated mass attached to the tricuspid valve was managed with nonsurgical treatment. No symptoms and complications attributable to the mass developed. Three years later, the size of the mass decreased. Here we report the case of a probable cardiac papillary fibroelastoma (PFE), a mobile mass, with a stalk on the septal leaflet of the tricuspid valve that was managed for three years without surgical treatment.

Native aortic valve thrombosis resembling papillary fibroelastoma.

Project description:The differential diagnosis of cardiac mass is important in determining the therapeutic plan and avoiding unnecessary surgical intervention. Non-invasive imaging methods would be useful in the diagnosis of suspected cardiac mass, because they may provide earlier diagnosis and more accurate assessment of cardiac mass. Native aortic valve thrombosis is a rare disorder and difficult to differentiate from a tumor, and in particular, a papillary fibroelastoma. Thus, the clinical decision making with imaging modalities should be performed cautiously. We recently met a female patient who had a aortic valve mass resembling papillary fibroelastoma in normal native valve. The patient underwent a surgical resection and the pathologic finding showed an organized thrombus with no evidence of papillary fibroelastoma.

Multimodality imaging of a giant aortic valve papillary fibroelastoma.

Project description:Papillary fibroelastomas (PFEs) are benign cardiac tumors arising from endocardium. They are commonly found on valvular surfaces and average 1.0-1.5 cm in size. Though often asymptomatic, PFEs can lead to potentially severe complications, primarily due to their embolic potential. Surgical resection is recommended for all symptomatic or large PFEs. We report the case of a patient presenting with cardiovascular symptoms who was found to have a very large aortic valve PFE, as diagnosed by histopathologic examination following surgical resection. Multimodality cardiovascular imaging demonstrates the classic morphologic findings, including a pedunculated appearance and oscillating "frond-like" surface projections.

Subaortic Membrane Papillary Fibroelastoma.

Project description:A 61-year-old male presented for an annual exam and received a transthoracic echocardiogram (TTE) which revealed a mobile mass arising from a subaortic membrane. Further investigations with a transesophageal echocardiogram (TEE) and cardiac computerized tomography angiography (CTA) confirmed the presence of a mobile 9 mm × 3 mm mass on a subaortic membrane. Cardiothoracic surgery was performed with an open operation removing the mass and subaortic membrane. Upon visual inspection, the mass was likened to a sea anemone and immunohistochemical staining performed pathologically confirmed the diagnosis of cardiac papillary fibroelastoma. This case represents the first reported example of a cardiac papillary fibroelastoma (PFE) arising from a subaortic membrane. Although PFEs are benign cardiac tumors, proper identification and consideration for excision of these lesions may be indicated to prevent thromboembolic complications.

Asymptomatic papillary fibroelastoma of the aortic valve in a young woman - a case report.

Project description:Echocardiography represents an invaluable diagnostic tool for the detection of intracardiac masses while simultaneously provides information about their size, location, mobility and attachment site as well as the presence and extent of any consequent hemodynamic derangement. A 29-year-old asymptomatic young woman with incidental transthoracic echocardiographic (TTE) discovery of an aortic valve mass is presented. The 2-dimensional TTE showed a mobile, pedunculated mass, attached by a thin stalk to the aortic surface of the right coronary aortic cusp at the junction of its base with the anterior aortic wall. The importance of valve sparing tumour resection even in asymptomatic patients is emphasised.

Multiple lipomata of the tricuspid valve and papillary muscle: case report.

Project description:BackgroundCardiac lipomas are rare benign primary tumours of the heart. Due to the nature of these tumours, they are often asymptomatic and diagnosed incidentally. Whether asymptomatic patients with cardiac lipomas should perform surgery still remains controversial.Case summaryA 34-year-old Asian male who was incidentally found hyperechoic masses in the right ventricle (RV) on the transthoracic echocardiogram by annually routine physical examination was admitted to our cardiology department. His medical history was unremarkable. The repeated transthoracic and transoesophageal echocardiogram showed multiple solitary and well-demarcated masses in the RV. On the cardiac magnetic resonance imaging, four discrete masses (considering the possibility of it being a lipoma) partially occluding the right ventricular outflow tract (RVOT) were observed. During the open-heart resection surgery, it was found that the tricuspid valve and papillary muscle were covered by multiple adipose masses in the RV that arose from the interventricular septum and the free wall, resulting in partial RVOT obstruction. These excised masses were histopathologically confirmed as lipomata characterized by the mature adipocytes with entrapped myocardial cells. The patient had no cardiac abnormality in the 1-month follow-up after the surgery.DiscussionThis rare clinical case of multiple lipomata of the tricuspid valve and papillary muscle acknowledges that multimodality imaging is the cornerstone for the assessment and diagnosis. Surgery should be performed in cases of symptomatic or large lipomas as well as when a lipoma is considered to be high risk because of RVOT obstruction.

Papillary fibroelastoma causing severe aortic stenosis.

Project description:Herein, we present a rare case of papillary fibroelastoma of the aortic valve, which caused severe aortic stenosis. The papillary fibroelastoma developed on the left ventricular side of the non-coronary cusp, immobilizing the cusp motion and obstructing the left ventricular outflow tract, resulting in severe aortic stenosis that brought on acute heart failure. The patient underwent an urgent surgical treatment, which resulted in a successful outcome. To the best of our knowledge, this is the first case of papillary fibroelastoma in which aortic stenosis was so severe as to cause congestive heart failure.Learning objectivePapillary fibroelastoma (PFE) is the most commonly observed primary cardiac tumor in adults that commonly involves left heart chambers. While PFEs often cause embolisms, they rarely cause valvular dysfunction. In a case presented herein, a PFE developed on the left ventricular side of the non-coronary cusp, immobilizing the cusp motion and obstructing the left ventricular outflow tract, resulting in severe aortic stenosis that brought on acute heart failure.
