Primary cardiac valve tumors

Papillary fibroelastoma of the aortic valve: analysis of 21 cases, including a presentation with cardiac arrest

Cardiac papillary fibroelastoma is a rare, benign tumor, arising predominantly from cardiac valves. This tumor can cause a variety of symptoms due to thromboembolism. We describe our single-center surgical experience with papillary fibroelastoma of the aortic valve. From April 2004 through June 2013, 6,530 patients underwent cardiac surgery. Of those, 6,098 patients were included in the final analysis. Twenty-one patients (0.34%) underwent surgical resection of 30 papillary fibroelastomas of the aortic valve. Most patients (67%) were incidentally diagnosed to have cardiac papillary fibroelastoma. The usual symptom was cerebral infarction (in 5 of 7 symptomatic patients). A rare presentation of papillary fibroelastoma in one patient was cardiac arrest caused by left main coronary artery ostial obstruction. Tumor size was not related to patient age (Pearson correlation coefficient, 0.34; P=0.13). Neither the number of tumors (1.43 ± 0.72 vs 1.43 ± 0.62) nor tumor size (8.14 ± 2.42 vs 8.07 ± 3.31 mm) was significantly different between symptomatic and asymptomatic patients. All lesions were resected by means of the simple shave technique. There were no operative or 30-day deaths. Follow-up echocardiograms showed no tumor recurrence (mean follow-up duration, 17 ± 14 mo). We identified no significant relationship among tumor size, number of tumors, symptoms, or patient age. Because simple shave excision of the tumor can be safely achieved without evidence of tumor recurrence, we conclude that surgical resection can be reasonable in asymptomatic patients.

[Unusual consequences of foam sclerotherapy]

Neurological disorders are rare complications of foam sclerotherapy. Visual disturbances and headache are the most commonly reported events and are thought to be equivalent to migraine with aura. Exceptionally, strokes have been reported. Papillary fibroelastoma is a rare cardiac tumor, which may embolize in cerebral arteries. We report the case of a patient in whom neurological disorders occurred during a session of foam sclerotherapy, and led to the discovery of a cardiac fibroelastoma.

Cardiac Papillary Fibroelastoma Originating from the Mitral Valve Chordae

Cardiac papillary fibroelastoma (CPF) is a rare benign primary cardiac neoplasm. In particular, CPF originating from the mitral valve chordae is extremely rare. A 74-year-old man was hospitalized for the evaluation of a cardiac mass in the left ventricle. Echocardiography revealed a mobile, spherical, pedunculated 2.1×2.1 cm mass at the mitral valve chordae with no mitral regurgitation. The patient underwent excision of the mass without repairing the mitral valve. A histological examination confirmed the mass to be a papillary fibroelastoma.

Paroxysmal sneezing at the onset of syncopes and transient ischemic attack revealing a papillary cardiac fibroelastoma

Sneezing can at times be associated with neurological disorders. The “sneeze center” is localized in the lateral medulla. We report the case of a 50-year-old man who presented three episodes of sneezing, two of them followed by an episode of transient gait instability and dizziness and the third one followed by an episode of transient left hemiparesis due to fibroelastoma of the aortic cardiac valve. To the best of our knowledge, this is the first description of a transient ischemic attack due to cardiac papillary fibroelastoma and revealed by violent episodes of sneezing.

Cardiac Masses on Cardiac CT: A Review

Cardiac masses are rare entities that can be broadly categorized as either neoplastic or non-neoplastic. Neoplastic masses include benign and malignant tumors. In the heart, metastatic tumors are more common than primary malignant tumors. Whether incidentally found or diagnosed as a result of patients' symptoms, cardiac masses can be identified and further characterized by a range of cardiovascular imaging options. While echocardiography remains the first-line imaging modality, cardiac computed tomography (cardiac CT) has become an increasingly utilized modality for the assessment of cardiac masses, especially when other imaging modalities are non-diagnostic or contraindicated. With high isotropic spatial and temporal resolution, fast acquisition times, and multiplanar image reconstruction capabilities, cardiac CT offers an alternative to cardiovascular magnetic resonance imaging in many patients. Additionally, cardiac masses may be incidentally discovered during cardiac CT for other reasons, requiring imagers to understand the unique features of a diverse range of cardiac masses. Herein, we define the characteristic imaging features of commonly encountered and selected cardiac masses and define the role of cardiac CT among noninvasive imaging options.

MRI of pediatric cardiac masses

OBJECTIVE

The purpose of this article is to describe the characteristic cardiac MRI features of primary and secondary cardiac tumors, including differentiation from masslike lesions, such as thrombus or focal myocardial hypertrophy.

CONCLUSION

The frequency and type of cardiac tumors in children differ from those in adults. Although transthoracic echocardiography is the initial imaging technique of choice for evaluation of cardiac tumors, cardiac MRI is an important complementary modality for characterization of the mass and effect on cardiac function.

Lipomatous hamartoma of mitral valve

Primary cardiac tumors are very rare, and tumors arising from cardiac valves are extremely rare. We present a case of lipomatous hamartoma of the mitral valve in a young female. This is the 6th case of lipomatous hamartoma of the mitral valve to be reported. We discuss the operative and histopathological findings.

Multiple papillary fibroelastomas and thrombus in the left heart

Cardiac papillary fibroelastomas (CPF) are benign cardiac tumors and usually discovered incidentally during echocardiography. This report describes the case of a 68-year-old man, referred to cardiology for multiple masses of the left ventricle and left atrium. The transthoracic echocardiography revealed multiple oscillating masses in the left ventricle and aortic valve, non-mobile mass in the left atrium with severe mitral stenosis and moderate aortic regurgitation. The patient underwent surgical resection of the masses with valve replacements. Histopathologic examination confirmed the diagnosis of CPF in the left ventricle and aortic valve, thrombus in the left atrium.

Papillary fibroelastoma of tricuspid valve presenting as pulmonary embolism

A 65-year-old gentleman was admitted with recurrent dyspnea. Two-dimensional and transesophageal echocardiography revealed a highly mobile echogenic mass attached to the tricuspid valve. A (99m)Tc lung perfusion scan was suggestive of pulmonary embolism. The patient underwent surgical resection of the mass. Histopathological examination revealed a papillary fibroelastoma.

CT and MRI of pulmonary valvular abnormalities

Pulmonary valve disease constitutes a wide spectrum of conditions. Traditionally, echocardiography has been the technique of choice for the evaluation of pulmonary and other valvular disease. However, with advances in technology, computed tomography (CT) and magnetic resonance imaging (MRI) are playing increasingly important roles in the evaluation of these disorders. In this article, we review the normal appearance of the pulmonary valve and then illustrate various variants and pathological entities of the pulmonary valve.

Multimodality imaging of right-sided (tricuspid valve) papillary fibroelastoma: recognition of a surgically remediable disease

Presentation of an increasingly recognized right-sided primary valve tumor of clinical importance: the tricuspid valve papillary fibroelastoma (PF). Early recognition and surgical intervention is emphasized for valvular PF, which carries a significant risk of morbidity and mortality. Newer imaging techniques, including CT and MRI, assist in localizing and differentiating PF from alternative cardiac pathology.

Papillary fibroelastoma of tricuspid valve in a pediatric patient

We are reporting a rare case of papillary fibroelastoma of the tricuspid valve in an 8-year-old child who presented with pulmonary embolism. Echocardiography was instrumental in determining the source of the pulmonary embolism, but not in delineating between tumor and thrombus. Successful surgical resection of the mass was accomplished and good outcome was attained despite the delay in diagnosis and failure of medical management. A high index of suspicion for tumor involving the tricuspid valve is emphasized despite its rarity in children.

MR imaging of cardiac tumors and masses: a review of methods and clinical applications

Cardiac masses are usually first detected at echocardiography. In their further evaluation, cardiac magnetic resonance (MR) imaging has become a highly valuable technique. MR imaging offers incremental value owing to its larger field of view, superior tissue contrast, versatility in image planes, and unique ability to enable discrimination of different tissue characteristics, such as water and fat content, which give rise to particular signal patterns with T1- and T2-weighted techniques. With contrast material-enhanced MR imaging, additional tissue properties such as vascularity and fibrosis can be demonstrated. MR imaging can therefore contribute to the diagnosis of a cardiac mass as well as be used to detail its relationship to other cardiac and extracardiac structures. These assessments are important to plan therapy, such as surgical intervention. In addition, serial MR studies can be used to monitor tumor regression after surgery or chemotherapy. Primary cardiac tumors are very rare; metastases and pseudotumors (eg, thrombus) are much more common. This article provides an overview of cardiac masses and reviews the optimal MR imaging techniques for their assessment.

Cardiac papillary fibroelastoma presenting as acute stroke

We present a case of a young woman who was initially diagnosed with acute stroke with no obvious risk factors. Preliminary investigation with transthoracic echocardiography and subsequent advanced imaging with transoesophageal echocardiography suggested the diagnosis of a benign cardiac tumour on the anterior leaflet of mitral valve. The patient underwent urgent surgical resection. Histology confirmed the diagnosis of cardiac papillary fibroelastoma. She made complete clinical recovery with no recurrence of symptoms.

Cardiac papillary fibroelastoma: a retrospect of four cases

OBJECTIVE

We have reviewed the medical histories of 4 patients who underwent operations between November 2004 and February 2011 at Changhai Hospital for cardiac papillary fibroelastoma.

METHODS

Diagnosis was demonstrably suggested by echocardiography. Tumor locations were mitral valve (1), left atrium (1), and aortic valve (2). Indications for operation were previous cerebrovascular accident for the mitral tumor, incidental apopsychia and giant mobile mass for the left atrium, ingravescent chest tightness and palpitations for the first aortic tumor, and severe regurgitation of aortic valve for the second aortic tumor. The study was approved by the Changhai Hospital Ethics Committee, and the consent from the patients or their immediate family was obtained.

RESULTS

Surgical excision with necessary valve replacement operations was performed 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 removed because of potential embolic complications.

An unusual case of giant cardiac fibroelastoma mimicking left atrial myxoma in a patient presenting with syncope

Cardiac papillary fibroelastomas are the most common primary valvular tumors. Generally benign, they account only for about 10% of all primary cardiac neoplasms, can occur in normal or diseased hearts, and are associated strongly with open heart surgery and radiotherapy. They are, in most cases, incidental findings, but can be discovered after syncope. We report the case of an elderly female, who was referred for syncope and was found to have a large fibroelastoma at the mitral valve annulus, intermittently obstructing the left ventricular inflow tract, and mimicking the presentation of left atrial myxoma. This case illustrates another potential mechanism of syncope in patients with fibroelastomas.

Fibroelastoma as a Culprit of Syncope

We present a case of a valvular mass diagnosed by emergency department bedside ultrasonography in a young patient with syncope. Bedside ultrasound has become a valuable tool in the evaluation of patients with syncope in the emergency department. This patient was believed to have a fibroelastoma on ultrasound that was confirmed by magnetic resonance and ultimately by postsurgical pathological evaluation. The indications and findings of using ultrasonography as part of the workup of syncope in the emergency department are discussed.

Surgical experience with cardiac papillary fibroelastoma over a 15-year period

BACKGROUND

Papillary fibroelastomas are rare, benign cardiac tumors. They are predominantly asymptomatic. However, they can lead to serious complications, namely thromboembolic events. Symptomatic lesions can be managed primarily with surgical excision and valvular preservation. Controversy exists as to the management of asymptomatic lesions.

METHODS

All patients diagnosed with cardiac papillary fibroelastoma between 1996 and 2012 at a single institution were queried for clinical and pathologic characteristics.

RESULTS

Twenty-three patients with 29 lesions were identified. Most lesions were solitary, less than 1.0 cm in diameter, and occurred in patients greater than 60 years of age. The most common presentation was thromboembolic complication. All were managed successfully with surgical excision. One patient developed a recurrence or metachronous lesion within 3 months of initial surgical intervention.

CONCLUSIONS

Papillary fibroelastomas are rare, benign, predominantly asymptomatic cardiac tumors that can cause potentially serious complications. The natural history and etiology of papillary fibroelastomas are largely unknown. Controversy exists over the management of asymptomatic lesions. However, there is consensus that symptomatic lesions should undergo surgical excision with valvular preservation when possible. A unique case of a possible papillary fibroelastoma recurrence is also described.

A rare case of aortic valve myxoma: easy to confuse with papillary fibroelastoma

Myxoma of the aortic valve is an exceedingly uncommon condition. In this article, we report the case of a 72-year-old man with myxoma arising from the aortic valve. We extirpated the mass and repaired the aortic valve with the patient under cardiopulmonary bypass. The postoperative course was uneventful. Histological examination confirmed that the mass was a myxoma.

An uncommon cause of renovascular hypertension

Renovascular hypertension is usually due to an atherosclerotic artery stenosis or a fibromuscular dysplasia. We describe an uncommon cause of renal ischemia. A 66-year-old woman was admitted for severe hypertension. During her stay, she presented an acute myocardial infarction with normal coronary angiography. After a flank pain, a contrast-enhanced abdominal computed tomography scan was performed which revealed a stenosis of the left main renal artery. However, renal angiography displayed a thrombosis. Transesophageal echocardiography showed a mobile mass attached to the mitral valve. A diagnosis of renal artery thrombosis and acute myocardial infarction both resulting from a cardiac tumour embolism was established.

Resolution of recurrent chest pain with resection of papillary fibroelastoma

Papillary fibroelastoma (PFE) is a benign primary tumor of the heart usually originating from the heart valves. Nonvalvular fibroelastomas are rare, and reported cases have presented either incidentally or with cerebral embolic phenomena; none have reported recurrent anginal symptoms. We are reporting a case of a 53-year-old female with history of significant radiation exposure to the chest in the past, who presented with recurrent chest pain and was found to have left atrial nonvalvular PFE managed with surgical excision. 

Surgical treatment for primary mitral valve tumor: a 25-year single-center experience

OBJECTIVE

Primary mitral valve (MV) tumor is a rare lesion, and to date, there have been few larger surgical series of MV tumors. We retrospectively analyzed 11 cases of primary MV tumors regarding clinical and pathological features, surgical procedure and long-term outcomes.

METHODS

From November 1983 to December 2008, we operated on 11 patients (age 36.3 ± 17.7 years, weight 55.4 ± 11.2 kg) with primary MV tumors. Symptoms were cardiac in 8 cases (72.7%) and neurologic in 3 (26.3%). Surgical procedures included en bloc excision and MV repair in 8 cases and tumor resection and MV replacement in 3. No radiotherapy or chemotherapy was given to patients with malignant tumors.

RESULTS

Pathological diagnosis was papillary fibroelastoma in 3 cases, myxoma in 3, lymphangioma in 1, lipoma in 1, hemangioma in 1 and sarcoma in 2. No early deaths or complications occurred. Late death occurred in 2 patients with sarcoma 1 year postoperatively. At the latest follow-up, with a maximum of 25 years (mean 10.6 ± 8.8), the 9 survivors were in New York Heart Association functional class I with normal MV function and no echocardiographic evidence of local recurrence.

CONCLUSIONS

The majority of primary MV tumors are benign. They can cause cardiac or neurologic symptoms and should be excised as soon as a diagnosis is made. For benign tumors, valve-sparing resection and valve repair are often possible with excellent long-term outcomes. The prognosis of malignant MV tumors is poor.

Papillary fibroelastoma of the aortic valve visualized by 320-slice computed tomography: report of a case

A 72-year-old man presented with a papillary fibroelastoma on the non-coronary cusp of the aortic valve. He was asymptomatic, with a history of hypertension and paroxysmal atrial fibrillation. Echocardiography revealed a mobile, round mass (13 × 15 mm) on the non-coronary cusp of the aortic valve. Scanning with 320-slice multi-detector row computed tomography (MDCT) also revealed a mass on the non-coronary cusp of the aortic valve. The tumor was subsequently excised from the aortic valve. In this case, the MDCT images were extremely clear and provided useful information like that obtained with echocardiography.

Environmental Pollution as a Cause of Papillary Fibroelastoma: Hints for a New Etiological Hypothesis?

<p><b>Background:</b> Environmental pollution has adverse human health effects, mostly on the respiratory tract but also on the cardiovascular system. Papillary fibroelastomas are exceedingly rare primary cardiac tumors; their pathologic origin remains still elusive.</p><p><b>Case Report:</b> This is a brief report on 3 patients referred for surgical treatment of papillary fibroelastomas in the last 6 months. All patients were born, lived, and worked in a narrow region in Campania that is under active monitoring because of high rates of environmental pollution.</p><p><b>Conclusions:</b> Known mechanisms of cardiovascular damage generated by environmental pollution are cross linked with described papillary fibroelastomas' etiological cascade. Evidence is suggested for a common origin. These results provide intriguing but inconclusive insights into pathophysiological pathways that may link exposure to environmental pollution and development of papillary fibroelastomas.</p>

A papillary fibroelastoma of the aortic valve that presented with repeated chest pain

A 70-year-old woman without any previous history of heart disease was referred to our hospital for repeated chest discomfort. She had experienced temporary hemiparesis because of a cerebral infarction of unknown etiology. Clinical evaluations were all within normal limits except for echocardiography. There was a mobile tumor in her ascending aorta, about 15 mm in diameter, adhering to a part of the right coronary cusp on its aortic side. Urgent surgery was performed. The tumor was attached to the edge of the right coronary cusp and excised with a part of the right coronary cusp, which was then repaired. Histological examination revealed the tumor to be a papillary fibroelastoma. The chest discomfort responsible for admission disappeared after the operation. In patients with events that may be embolic in nature and are not explained by other cardiovascular or neurological diseases, a cardiac source of emboli should be considered.

Intracardiac lipoma arising from the papillary muscle

Cardiac lipoma is the commonest nonmyxomatous benign primary cardiac tumor. We report a case of lipoma arising from the anterolateral papillary muscle and presenting with a transient ischemic episode and a history of malignant melanoma. The lipoma was removed leaving the mitral apparatus intact. 

Primary cardiac valve tumors

To assess the prevalence, characteristics, and outcome of surgical treatment of primary cardiac valve tumors in a single center, we reviewed our experience in 6 women and 1 man, aged 49 to 76 years (mean, 64.7 years) who presented between 1999 and 2006. In one patient, the diagnosis of cardiac valve tumor was made incidentally on transesophageal echocardiography during aortocoronary bypass surgery. The others had clinical symptoms: angina or myocardial infarction in 3, congestive heart failure in 2, dyspnea and cerebrovascular ischemia in 1 patient each. Four of the 7 tumors were benign, and 3 were malignant. All patients survived the operation and recovered uneventfully. Midterm follow-up was available in all patients. Two patients with malignant tumors were considered unsuitable for adjuvant therapy by the oncologist; both died during follow-up from local tumor recurrence. All 5 survivors were categorized at the last follow-up as functional class I, with normal exercise tolerance. Excellent early and midterm surgical results can be obtained in patients with benign cardiac valve tumors, but the prognosis for those with a malignant tumor is poor.

Papillary fibroelastoma presenting as a left ventricular mass

Cardiac papillary fibroelastoma (CPF) is a benign cardiac tumor that usually affects cardiac valves. It is usually discovered incidentally on routine echocardiography. However, left ventricular CPF is rare. This report describes the case of a 73-year-old female, referred to a cardiology department for evaluation of a mass of the left ventricle. The mass was found routine echocardiography. The transthoracic echocardiography revealed a 2.2x1.3 cm highly oscillating mass, attached by stalk on the inferior wall of the left ventricle. Cardiac magnetic resonance imaging demonstrated a non-enhanced, 1.8x1.0 cm mass on the inferior wall of the left ventricle. The patient underwent surgical resection of the mass, histopathologic examination of the mass confirmed the diagnosis of a CPF.

Multidetector computed tomography findings of a papillary fibroelastoma of the aortic valve: a case report

Papillary fibroelastoma is a rare benign cardiac tumor that represents 10% of all primary cardiac tumors. Diagnosis is accomplished incidentally by echocardiography that is usually performed for another purpose. Most papillary fibroelastomas are asymptomatic, but the lesions are recognized as a cause of embolisms. To the best of our knowledge, there has been no case report of computed tomography findings of a papillary fibroelastoma. We report a case of a papillary fibroelastoma in a 78-yr-old woman who had dyspnea and chest tightness. Echocardiography revealed a small lobulated mobile echogenic mass attached to the aortic valve, and CT demonstrated a lobulated soft tissue density mass with a thin stalk at the sinotubular junction of the aortic valve.

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.
