Cardiac papillary fibroelastoma originating from pulmonary vein--a case report

Unusual Location of a Papillary Fibroelastoma Causing a Multi-territorial Stroke

A 56-year-old male presented with a multi-territorial stroke without traditional cerebrovascular risk factors. A transesophageal echocardiogram revealed an intracardiac lesion attached to the lateral wall of the left atria, consistent with an atrial myxoma. Surgical excision of the lesion was performed and revealed that lesion was in fact a papillary fibroelastoma with thrombus attached, which demonstrates a novel mechanism by which intracardiac masses can cause cerebral events.

Cardiac papillary fibroelastoma arising from the opening of the left inferior pulmonary vein in left atrium: A rare case report

RATIONALE

Cardiac papillary fibroelastoma is a small, benign endocardial tumor, while it is clinically important because of its strategic position and propensity for causing embolic events and hemodynamic complications.

PATIENT CONCERNS

A 59-year-old female presented our hospital for investigation and treatment of a sudden onset of syncope lasted about 2 minutes.

DIAGNOSES

Cardiac papillary fibroelastoma arising from left inferior pulmonary vein in left atrium.

INTERVENTIONS

The tumor was successfully removed by cardiac surgery.

OUTCOMES

The patient's postoperative course was uneventful, and she was discharged 10 days after surgery. The patient remained free of neurologic deficits and had no evidence of residual or recurrence of tumor with echocardiography during 1 year of follow-up.

LESSONS

Cardiac papillary fibroelastoma is a benign tumor, with increased risk of thromboembolic events. It is often diagnosed in patients with echocardiography by chance or after a neurologic event. Complete surgical resection should be considered when the patient is indicated and the long-term postoperative prognosis is excellent.

[Papillary fibroelastoma of mitral leaflet revealed by a cerebrovascular accident. Case report]

Papillary fibroelastoma is a benign primitive cardiac tumour, which can be associated with serious embolic complications. We report on a 37-year-old woman admitted for a cerebrovascular accident. Transthoracic and transesophageal echocardiography revealed a small and pedunculated mass attached to the anterior mitral leaflet. Because of the severity of its symptoms and its high embolic potential, the tumour was surgically excised and histologically diagnosed as a papillary fibroelastoma. The postoperative period was uneventful and the patient was discharged at the third day. Papillary fibroelastoma must be surgically treated because of its high embolic potential and its severe prognosis.

Thrombus or tumor? a case of fibroelastoma as indicated during the submission process

We describe the case of a 50-year-old woman who was admitted to a pheriferal department for heart failure. The echocardiography revealed a small mass measuring about 1.3 x 1.0 cm adhering to the non-coronary cusp of the aortic valve, mild dilated cardiomiopathy and severe biventricular dysfunction. This mass had erroneously been considered a thrombotic lesion, so the patient was treated with thrombolysis and heparin e.v. Only after a transoesophageal echocardiography a tumour cardiac mass was suspected. The diagnosis of fibroelastoma was confirmed by MRI and then from the anatomic and histoligical definition after surgery.

Left atrial papillary fibroelastoma: a rare cause of multiple cerebral emboli

Papillary fibroelastomas have been increasingly described since the widespread use of cardiac echocardiography. Most often diagnosed incidentally, papillary fibroelastomas may embolize, mainly to the cerebral circulation. The aortic valve is predominantly affected. The left ventricle is the most frequent nonvalvular location. We present a case of a 59-year-old man who had recurrent episodes of cerebral ischemic attacks and required coronary artery bypass surgery. The overall neurologic investigation was normal, including a transthoracic echocardiography. A 5 x 5 mm pedunculated, mobile mass was described on the intraoperative transesophageal echocardiography. The excision was performed through the left atrial appendage during the coronary artery bypass surgery. The microscopic examination demonstrated a papillary fibroelastoma. The unusual localization and management of papillary fibroelastomas are discussed.

Papillary Fibroelastoma Arising from the Left Atrial Free Wall

Primary cardiac tumors are rare. Papillary fibroelastomas represent the second or third most common benign cardiac tumor and the most common one associated with heart valves. Nonvalvular endocardial location of this tumor is extremely rare. We present a case of a papillary fibroelastoma arising from the left atrial (LA) free wall.

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.
