Detection of multiple papillary fibroelastomas of the tricuspid valve by transesophageal echocardiography

Pulmonary Valve Papillary Fibroelastoma. A Case Report

We present a case of pulmonary valve fibroelastoma diagnosed by echocardiogram which was confirmed by surgical resection in a patient in whom elective coronary artery bypass surgery was performed. The patient had no clinical or constitutional symptoms suggesting the presence of an intracardiac tumor. Routine preoperative transthoracic echocardiography revealed a pulmonary valve tumor. Histopathological analysis resulted in a diagnosis of papillary fibroelastoma. Papillary fibroelastomas are rare and benign cardiac tumors. They usually arise from the cardiac valves. In the literature we found only a few cases, so it seems there is a need for further description of additional cases of pulmonary valve fibroelastoma.

Multiple papillary fibroelastomas attached to left ventricular side and aortic side of the aortic valve: A report of new case and literature review

The aortic valve (AV) is the most commonly affected site in multiple papillary fibroelastomas, but the frequency of embolism caused by the attachment side of the AV has not been elucidated. According to the review of the previous literature, 16 cases have been found attached to the AV. Of these, 6 of these have been found to be attached on the aortic side and 4 on the left ventricular side, 1 was bilateral, and 5 cases were unknown. Of the cases found on the aortic side, embolism occurred in 3 of them, and of the left ventricular side cases, embolism occurred in 2 of them. The frequency of embolism is equivalent even if papillary fibroelastoma attached to either side of the AV.

Cardiac fibroelastoma: a rare cause of stroke in young adults

A 26-year-old man presenting with a transient episode of dysarthria and dizziness, 3 weeks prior to admission, was referred to our center to be evaluated for transient ischemic attack (TIA). The patient had been previously admitted to a different hospital and echocardiography was reported normal at that center, but upon presenting to our institution strand-like masses in the left ventricle (LV) were detected. Transesophageal echocardiography (TEE) revealed two distinct mobile LV masses suggesting a diagnosis of papillary fibroelastoma. CT angiography and histopathological studies confirmed this diagnosis.

Papillary fibroelastoma of the tricuspid anterior leaflet

The case of a 50-year-old woman with an occasional diagnosis of cardiac tumor of the tricuspid valve is reported. At surgery, a single 2 cm x 2 cm polypoid gelatinous neoplasm infiltrating the anterior leaflet of the valve was resected and a tricuspid valve reconstruction along with annuloplasty was accomplished. The postoperative period was uneventful. A diagnosis of papillary fibroelastoma was made at pathology. This neoplasm, which represents a rare pathological entity, is more frequently localized on the mitral valve and usually stays asymptomatic for a long time. Only a few cases involving the tricuspid and pulmonary valves have been reported. Indication for surgery is related to a certain incidence of pulmonary embolism. Surgical removal of papillary fibroelastoma is a low-risk and definitive operation, as only one case of recurrence of the tumor has been reported so far in the literature.

Papillary fibroelastoma of the pulmonary valve

A papillary fibroelastoma is rare, but it is the most common primary tumor of the cardiac valves. Most papillary fibroelastomas affect the left-sided heart valves, such as the aortic and mitral valves; however, they also rarely affect the pulmonary valve. Generally, surgical removal is strongly recommended to prevent its potential thromboembolic risks, especially in cases of left-sided cardiac involvement. However, there are few reports on the treatment of asymptomatic, small, right-sided cardiac fibroelastomas. We present a rare case of an asymptomatic papillary fibroelastoma occurring on the pulmonary valve, which was detected by transthoracic echocardiography, transesophageal echocardiography, and a 64-slice cardiac computed tomography scan, and which was surgically removed.

Papillary fibroelastoma of the right atrium as an unusual source of recurrent pulmonary embolism

Papillary fibroelastoma is the most common primary tumour of cardiac valves, with the potential for embolic events and obstructive effects. Location in non-valvular endocardium is extremely rare. Transthoracic and transoesophageal echocardiography have greatly increased the ability to make the diagnosis of these surgically treatable tumours in a timely fashion. We report the case of a 70-year-old woman with symptoms and ventilation-perfusion scan evidence of pulmonary embolization from a papillary fibroelastoma of the right atrium. Initial transthoracic echocardiography failed to identify the tumour, whereas transoesophageal echocardiography demonstrated a mobile echodense mass attached to the right atrial free wall. After surgical excision, histopathology revealed papillary fibroelastoma. The epidemiology, aetiology, localization, macroscopy, histopathology, immunohistochemistry, clinical presentation, diagnosis and management of cardiac papillary fibroelastoma are reviewed. The case is unusual with respect to the site of origin of the papillary fibroelastoma as well as its clinical presentation, which is clearly related to pulmonary embolization.

Double primary left ventricular and aortic valve papillary fibroelastoma

Papillary fibroelastomas of the heart are relatively rare benign tumors and although they can be symptom free, symptoms such as cerebral ischemia and cardiac infarction can be lethal. It is important to diagnose this tumor using echocardiography, because lethal embolisms can be prevented by surgical resection. Recurrence of this tumor has not been reported and multiple tumors are rare. The present report is a case of double primary aortic valve fibroelastoma with aortic regurgitation diagnosed 4 years after surgery for a left ventricular fibroelastoma with mitral valvular disease.

Cardiac papillary fibroelastoma: a comprehensive analysis of 725 cases

BACKGROUND

With the advent of echocardiography, cardiac papillary fibroelastoma (CPF) is being increasingly reported. The demographics, clinical characteristics, pathological features, treatment, and prognosis of CPF are examined.

DATA COLLECTIONS

Cases, case series and related articles on the subject in all languages were identified through a comprehensive literature search.

RESULTS AND CONCLUSIONS

Seven hundred twenty-five cases of CPF were identified. Males comprised 55% of patients. Highest prevalence was in the 8th decade of life. The valvular surface was the predominant locations of tumor. The most commonly involved valve was the aortic valve, followed by the mitral valve. The left ventricle was the predominant nonvalvular site involved. No clear risk factor for development of CPF has been reported. Size of the tumor varied from 2 mm to 70 mm. Clinically, CPFs have presented with transient ischemic attack, stroke, myocardial infarction, sudden death, heart failure, presyncope, syncope, pulmonary embolism, blindness, and peripheral embolism. Tumor mobility was the only independent predictor of CPF-related death or nonfatal embolization. Symptomatic patients should be treated surgically because the successful complete resection of CPF is curative and the long-term postoperative prognosis is excellent. The symptomatic patients who are not surgical candidates could be offered long-term oral anticoagulation, although no randomized controlled data are available on its efficacy. Asymptomatic patients could be treated surgically if the tumor is mobile, as the tumor mobility is the independent predictor of death or nonfatal embolization. Asymptomatic patients with nonmobile CPF could be followed-up closely with periodic clinical evaluation and echocardiography, and receive surgical intervention when symptoms develop or the tumor becomes mobile.

An unusual case of multiple papillary fibroelastoma, review of literature

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.

Clinical and echocardiographic characteristics of papillary fibroelastomas: a retrospective and prospective study in 162 patients

BACKGROUND

Cardiac papillary fibroelastoma (CPF) is a primary cardiac neoplasm that is increasingly detected by echocardiography. The clinical manifestations of this entity are not well described.

METHODS AND RESULTS

In a 16-year period, we identified patients with CPF from our pathology and echocardiography databases. A total of 162 patients had pathologically confirmed CPF. Echocardiography was performed in 141 patients with 158 CPFs, and 48 patients had CPFs that were not visible by echocardiography (<0.2 cm), leaving an echocardiographic subgroup of 93 patients with 110 CPFs. An additional 45 patients with a presumed diagnosis of CPF were identified. The mean age of the patients was 60+/-16 years of age, and 46.1% were male. Echocardiographically, the mean size of the CPFs was 9+/-4.6 mm; 82.7% occurred on valves (aortic more than mitral), 43.6% were mobile, and 91.4% were single. During a follow-up period of 11+/-22 months, 23 of 26 patients with a prospective diagnosis of CPF that was confirmed by pathological examination had symptoms that could be attributable to embolization. In the group of 45 patients with a presumed diagnosis of CPF, 3 patients had symptoms that were likely due to embolization (incidence, 6.6%) during a follow-up period of 552+/-706 days.

CONCLUSIONS

CPFs are generally small and single, occur most often on valvular surfaces, and may be mobile, resulting in embolization. Because of the potential for embolic events, symptomatic patients, patients undergoing cardiac surgery for other lesions, and those with highly mobile and large CPFs should be considered for surgical excision.

Organized thrombus of the tricuspid valve mimicking valvular tumor

We report on a case of organized thrombus of the tricuspid valve mimicking a valve tumor. Preoperative transesophageal echocardiography showed the mass to have originated from the septal leaflet of the tricuspid valve. A pouch of the tricuspid valve and a ventricular septal defect were observed perioperatively, with the mass attached to the septal leaflet. Histologic examination revealed the mass to be an organized thrombus without tumor components.

Papillary fibroelastoma of the mitral valve with systemic embolization

Primary tumors of the heart are rare disorders. In autopsy studies, their incidence was reported to be 0.01-0.5%. We present the case of a papillary fibroelastoma of the mitral valve with systemic embolization in a young man.

Papillary fibroelastoma: increasing recognition of a surgical disease

Papillary fibroelastomas are uncommon benign tumors usually involving the heart valves, which historically have been diagnosed at autopsy. With the advent of echocardiography, however, the number of patients diagnosed in life has increased. Papillary fibroelastomas represent a surgically treatable cause of cerebrovascular and cardiovascular ischemia and infarction making their identification clinically important. We report three unusual cases of papillary fibroelastoma; two patients presenting with symptoms of cerebrovascular ischemia and one presenting with myocardial infarction. We also present a comprehensive review of the literature and provide a compilation of all case reports to date.

Cardiac valve papillary fibroelastoma: surgical excision for revealed or potential embolization

OBJECTIVE

We have reviewed the case histories of 4 patients who underwent operations between September 1994 and November 1997 at Broussais Hospital for cardiac valvular papillary fibroelastoma.

METHODS

Diagnosis was strongly suggested by echocardiography. Tumor locations were mitral (1), tricuspid (1), and aortic (2). Indications for operation were previous stroke for the mitral tumor, prophylaxis for the tricuspid tumor, syncopal episodes for the first aortic tumor, and transient ischemic attack and mesenteric ischemia for the second aortic tumor.

RESULTS

Surgical excision with a conservative, valve-sparing approach was performed in all cases. For the first aortic tumor, aortic valve reconstruction was achieved with part of a cryopreserved aortic homograft cusp. Intraoperative transesophageal echocardiography showed no evidence of valvular regurgitation after excision in all cases. All patients had uneventful postoperative recoveries. No evidence of regurgitation or recurrence was seen on echocardiography at follow-up.

CONCLUSIONS

Despite their histologically benign aspect, cardiac papillary fibroelastomas should be excised because of potential embolic complications. A conservative, valve-sparing approach is recommended, however, because of the absence of recurrence after total excision.
