Abstract
Diagnosing atrial myxoma in pregnancy is challenging because patients may present with non-specific symptoms that might be overlooked. The timing of non-obstetric operation usually depends on the nature of the disease, after careful consideration of feto-maternal safety, including the use of cardiopulmonary bypass and placental transfer of anaesthetic drug. A woman in her 30s at 18 weeks of pregnancy presented with recurring dizziness. She underwent successful myxoma excision at 20 weeks under general anaesthesia and cardiopulmonary bypass. The 6×5 cm myxoma was histologically confirmed as myxoma. Early detection of atrial myxoma in pregnancy is crucial, and a clinician has to consider the diagnosis of left atrial myxoma with mitral valve obstruction as a cause of severe dizziness. Optimal outcomes require multidisciplinary management. In this case, surgery during the second trimester of pregnancy enabled a full-term pregnancy with the patient's and foetal well-being and normal postprocedural echocardiography.

Takotsubo syndrome and atrial myxoma-identifying a new trigger: a case report. Front Cardiovasc Med 2024; 11:1323492. [PMID: 38414925 PMCID: PMC10897023 DOI: 10.3389/fcvm.2024.1323492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 01/29/2024] [Indexed: 02/29/2024] Open
Abstract
Takotsubo syndrome (TTS) is a rare cardiomyopathy, but its prevalence is increasing due to the greater availability of diagnostic tools, whose pathophysiology is unknown; however, the evidence points to an excess of catecholamines that ends up generating cardiac stunning. The cause of excessive sympathetic discharge is multifactorial, and some tumors may be related to their origin. In this case report, we present a female patient with TTS whose only identified triggering factor was an atrial myxoma, which generated an unusual clinical presentation. Current multimodal diagnostic tools together with the multidisciplinary evaluation of the HeartTeam allowed an accurate diagnosis and an adequate management of the clinical picture.

A polo ball in the right atrium, importance of echocardiographic characteristics of intracardiac myxomas: a case report. J Med Case Rep 2023; 17:403. [PMID: 37730679 PMCID: PMC10512563 DOI: 10.1186/s13256-023-04130-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 08/14/2023] [Indexed: 09/22/2023] Open
Abstract
BACKGROUND Myxomas are the most prevalent type of heart tumors, mainly occurring in the left atrium, with approximately 20% of cases found in the right atrium. Timely diagnosis and appropriate management of myxomas are crucial for favorable outcomes and to minimize complications. CASE PRESENTATION A 77-year-old Asian male with no significant medical history presented with intermittent trepopnea and palpitations. Physical examination revealed regular heart sounds and no other relevant findings. A transthoracic echocardiogram showed a large, round-shaped, smooth-edged mass with diameter of 86 mm, occupying most of the right atrium. Mild tricuspid flow obstruction and mild left ventricular systolic dysfunction were also observed. Cardiac tomography confirmed the size, smooth edges, and showed microcalcifications of the mass, with no invasion of surrounding tissues. Surgical intervention successfully removed the spheroid mass, leading to the alleviation of symptoms. Histopathology confirmed the myxoma nature of the mass. A comprehensive discussion based on relevant medical literature is provided, with emphasis on echocardiographic characteristics of the mass with relation to potential embolic disease. CONCLUSION This case shows an atypical presentation of an exceptionally large myxoma in the right atrium, resembling the size of a polo ball, in a patient presenting with supraventricular arrhythmia and trepopnea. Early diagnosis and appropriate management played a vital role in achieving a successful outcome for the patient.

Abstract
Atrial myxomas are primary cardiac tumors which may cause ischemic stroke. The authors present a case of a 51-year-old man admitted to the emergency department with right-sided hemiplegia and aphasia caused by ischemic stroke. 2D and 3D transesophageal echocardiography showed an atrial myxoma described as a large mass in the left atrium attached to the interatrial septum. In the end, surgical excision of the myxoma was performed 48 h after diagnosis. Nowadays, specific guidelines concerning the correct time for surgical excision of the myxoma are lacking. The authors highlight the utmost role of echocardiography to promptly characterize a cardiac mass and the importance of discuss about the timing of cardiac surgery.

Clinical features, risk factors and survival in cardiac myxoma-related ischemic stroke: A multicenter case-control study. J Neurol Sci 2023; 444:120517. [PMID: 36528975 DOI: 10.1016/j.jns.2022.120517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 11/11/2022] [Accepted: 12/04/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Cardiac myxoma (CM) is an important etiology of stroke in young adults, but studies on CM-related ischemic stroke (CM-IS) are limited and conflicting. Hence, we investigated clinical characterizations, risk factors of CM-IS, and short-term survival after surgical resection. METHODS We performed a retrospective analysis of data from all CM patients at three referral management centers and conducted follow-up examination. RESULTS Among 414 CM patients, 402 were recruited for further analysis, including 54 patients with CM-IS and 348 patients with CM without stroke (Non-stroke). In the acute phase, patients presented with NIHSS 3 (interquartile range: 0-10) and clinical presentation comprising neurological, cardiac and constitutional symptoms. Multivariate analysis showed that the factors associated with an increased risk of CM-IS were tumor width < 30 mm [OR = 2.652, 95% CI: 1.061-6.627, P = 0.037], tumors with high-mobility (OR = 2.700, 95% CI: 1.357-5.371, P = 0.005), thrombus on the tumor surface (OR = 1.856, 95% CI: 1.003-3.434, P = 0.049), and lower B-type natriuretic peptide (BNP) levels (OR = 0.995, 95% CI: 0.989-0.999, P = 0.047). The overall three-year survival rate was 95.7% (95% CI: 94.9-96.5) in CM-IS patients who underwent surgery. CONCLUSIONS CM-IS patients had mild or moderate neurologic deficits with various presentations at disease onset. Narrower tumor width, tumors with high-mobility, thrombus on the tumor surface, and lower BNP levels are potential predictors of CM-IS development. Surgical removal of CM is safe and efficacious in patients with CM-IS.

Risk factors assessment and a Bayesian network model for predicting ischemic stroke in patients with cardiac myxoma. Front Cardiovasc Med 2023; 10:1128022. [PMID: 37034338 PMCID: PMC10079949 DOI: 10.3389/fcvm.2023.1128022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 03/06/2023] [Indexed: 04/11/2023] Open
Abstract
Objective This study aims to identify relevant risk factors, assess the interactions between variables, and establish a predictive model for ischemic stroke (IS) in patients with cardiac myxoma (CM) using the Bayesian network (BN) approach. Methods Data of patients with CM were collected from three tertiary comprehensive hospitals in Beijing from January 2002 to January 2022. Age, sex, medical history, and information related to CM were extracted from the electronic medical record system. The BN model was constructed using the tabu search algorithm, and the conditional probability of each node was calculated using the maximum likelihood estimation method. The probability of each node of the network and the interrelationship between IS and its related factors were qualitatively and quantitatively analyzed. A receiver operating characteristic (ROC) curve was also plotted. Sensitivity, specificity, and area under the curve (AUC) values were calculated and compared between the BN and logistic regression models to evaluate the efficiency of the predictive model. Results A total of 416 patients with CM were enrolled in this study, including 61 with and 355 without IS. The BN model found that cardiac symptoms, systemic embolic symptoms, platelet counts, and tumor with high mobility were directly associated with the occurrence of IS in patients with CM. The BN model for predicting CM-IS achieved higher scores on AUC {0.706 [95% confidence interval (CI), 0.639-0.773]} vs. [0.697 (95% CI, 0.629-0.766)] and sensitivity (99.44% vs. 98.87%), but lower scores on accuracies (85.82% vs. 86.06%) and specificity (6.56% vs. 11.48%) than the logistic regression model. Conclusion Cardiac symptoms, systemic embolic symptoms, platelet counts, and tumor with high mobility are candidate predictors of IS in patients with CM. The BN model was superior or at least non-inferior to the traditional logistic regression model, and hence is potentially useful for early IS detection, diagnosis, and prevention in clinical practice.

Abstract
Studying cardiac masses is one of the most challenging tasks for cardiac imagers. The aim of this review article is to focus on the modern imaging of cardiac masses proceeding through the most frequent ones. Cardiac benign masses such as myxoma, cardiac papillary fibroelastoma, rhabdomyoma, lipoma, and hemangioma are browsed considering the usefulness of most common cardiovascular imaging tools, such as ultrasound techniques, cardiac computed tomography, cardiac magnetic resonance, and in the diagnostic process. In the same way, the most frequent malignant cardiac masses, such as angiosarcoma and metastases, are highlighted. Then, the article browses through nontumoral masses such as cysts, mitral caseous degenerative formations, thrombi, and vegetations, highlighting the differential diagnosis between them. In addition, the article helps in recognizing anatomic normal variants that should not be misdiagnosed as pathological entities.

Abstract
Pulmonary artery intimal sarcoma (PAIS) is a rare tumor with an incidence of 0.001%-0.03% that usually grows along artery walls and absorbs fluorodeoxyglucose. It is difficult to distinguish PAIS from pulmonary thromboembolism due to the similarities of their symptoms. Therefore, contrast-enhanced computed tomography and positron emission tomography-computed tomography (PET-CT) should be used to establish a correct diagnosis. Here we report a case of an extremely rare type of PAIS, pedunculated PAIS, which could not be visualized on PET-CT. Histological features of a tumor with a low accumulation of fluorodeoxyglucose revealed low-cellularity and necrotizing background. Multimodal imaging was useful to diagnose PET-CT negative PAIS accurately. <Learning objective: Pedunculated pulmonary artery intimal sarcoma (PAIS) is a rare form of neoplasm. You need to know that PAIS which has low cellularity with marked interstitial myxoid tissue cannot be detected on positron emission tomography-computed tomography.>.

Abstract
Mitral valve prolapse (MVP) is a commonly occurring heart condition defined by enlargement and superior displacement of the mitral valve leaflet(s) during systole. Although commonly seen as a standalone disorder, MVP has also been described in case reports and small studies of patients with various genetic syndromes. In this review, we analyzed the prevalence of MVP within syndromes where an association to MVP has previously been reported. We further discussed the shared biological pathways that cause MVP in these syndromes, as well as how MVP in turn causes a diverse array of cardiac and noncardiac complications. We found 105 studies that identified patients with mitral valve anomalies within 18 different genetic, developmental, and connective tissue diseases. We show that some disorders previously believed to have an increased prevalence of MVP, including osteogenesis imperfecta, fragile X syndrome, Down syndrome, and Pseudoxanthoma elasticum, have few to no studies that use up-to-date diagnostic criteria for the disease and therefore may be overestimating the prevalence of MVP within the syndrome. Additionally, we highlight that in contrast to early studies describing MVP as a benign entity, the clinical course experienced by patients can be heterogeneous and may cause significant cardiovascular morbidity and mortality. Currently only surgical correction of MVP is curative, but it is reserved for severe cases in which irreversible complications of MVP may already be established; therefore, a review of clinical guidelines to allow for earlier surgical intervention may be warranted to lower cardiovascular risk in patients with MVP.

Abstract
The Carney complex (CNC) is a rare autosomal dominant genetic complex that is characterised by multiple neoplasms consisting of neuroendocrine and cardiac tumours, with only 750 cases reported worldwide as of 2017. Cardiac tumours, in the context of the CNC, are of unique importance since the leading causes of death in patients with CNC are cardiac. To prevent sudden cardiac death and embolic events, a difficult diagnosis must be made and postdiagnostic screenings must be regular. We present a case of a 52-year-old man, with a medical history of pituitary microadenoma and facial lentiginosis, who presented with dyspnoea 2 months after suffering a cerebrovascular accident.

Abstract
BACKGROUND Although rare, atrial myxoma is the most common benign cardiac tumor. The recognized triad of presenting symptoms relates to constitutional, embolic, and obstructive effects produced by the tumor. However, the presentation may be non-specific and mimic other diseases, confounding diagnosis. CASE REPORT A middle-aged woman presented with wheezing and shortness of breath. With a strong background smoking history, the initial impression was that of acute bronchospasm. She however deteriorated rapidly, with decreased consciousness and cardiac arrest requiring resuscitation. Despite intensive care management, she died within 1 day of admission. Autopsy revealed a previously undiagnosed left atrial myxoma with coronary and systemic embolization. CONCLUSIONS This case highlights an unusual presentation of atrial myxoma, resulting in fatal simultaneous embolization to the coronary and cerebral arteries. This simultaneous embolic presentation is not common, but the potential consequences are serious. This report also demonstrates that the presentation of a left-sided atrial myxoma with cardiac asthma can mimic respiratory disease and confound diagnosis. In adult patients without a history of chronic respiratory disease, the possibility of cardiac asthma should always be entertained. Furthermore, the importance of considering atrial myxoma as a cause for cardiac asthma is emphasized. The use of transthoracic echocardiogram in aiding the rapid diagnosis of atrial myxoma is recommended. Finally, the continued acknowledgement of the important contribution the academic autopsy makes in complementing and improving clinical practice remains imperative.

Abstract
Atrial myxoma is a benign primary heart tumour, which can be found incidentally on imaging studies. It is usually located in the left atrium and may manifest as dyspnoea, chest pain, heart failure, cough, shortness of breath when rising from a recumbent position, haemoptysis, hoarseness and as a source of cardiac embolism. However, dysphagia caused by an atrial myxoma has been reported only twice in the literature. We present a 53-year-old Caucasian man with a chronic history of dysphagia caused by an atrial myxoma, in which surgical resection resulted in complete resolution of his dysphagia.

Abstract
Primary cardiac valve tumours are rare. This is a case report of a 32-year-old non-smoker man with a history of stroke 1 year prior and no other cardiovascular risk factors. The patient was admitted to our acute stroke ward for recurrent left hemiparesis, slurring of speech, facial asymmetry and central retinal artery occlusion. Initial laboratory investigations and ECG were normal. An urgent CT brain showed a large hypodense area at the right frontal, parietal, temporal, occipital region with effaced sulci and right lateral ventricle with midline shift and cerebral oedema in keeping with acute infarction. We proceeded with CT angiography of the cerebral and carotid on the following day, which revealed no evidence of thrombosis, aneurysm or arteriovenous malformation. There were no abnormal beaded vessels to suggest vasculitis. Transthoracic echocardiography revealed a large mobile mass in the left atrium. Meanwhile, MRI cardiac confirmed a large ill-defined mobile solid mass attached to the mitral valve's inferoseptal component suggestive of mitral valve myxoma. This case report highlights the significance of considering a cardiogenic source of emboli in patients with large cerebral infarcts and other cardiac embolic phenomena. Imaging modalities such as echocardiography and cardiac MRI will help detect treatable conditions, such as valvular myxoma and prevent further complications.

Abstract
Background The risk factors contributing to embolism in cardiac myxoma (CM) are yet controversial. This systematic review and meta-analysis aimed to clarify the risk factors of embolism for the CM patients. Methods PubMed, Embase, Cochrane library, Web of Science, China National Knowledge Infrastructure, Wan Fang, and Wei Pu databases were searched from inception to June 2019. Statistical analysis was conducted using Stata version 14.0. The pooled odds ratio or mean difference with 95% confidence interval was estimated for each risk factor. Results Herein, 12 studies, encompassing 1814 patients, were included. The pooled results suggested that New York Heart Association (NYHA) class I/II (P < 0.01), hypertension (P = 0.03), irregular tumor surface (P < 0.01), tumor in atypical location (P = 0.01), narrow base of tumor (P < 0.01), and increased fibrinogen (FIB) (P < 0.01) are significant risk factors of embolism in CM patients. However, sex, age, body mass index, smoking, left ventricular ejection fraction, diabetes, hyperlipidemia, atrial fibrillation, valvular heart disease, coronary heart disease, tumor size, platelet count, white blood cells, and hemoglobin were not associated with embolism (all P > 0.05). Conclusions NYHA class (I/II), hypertension, irregular tumor surface, atypical tumor location, the narrow base of tumor, and increased FIB were significant risk factors of embolism in CM patients. For CM patients with these factors, early surgery might be beneficial to prevent embolism.

Abstract
Background Embolic stroke is a common complication of atrial myxoma, whereas multiple cerebral aneurysms associated with atrial myxoma is rare. The pathogenesis of the cerebral vascular disease related to an atrial myxoma is still not well known, and there are no guidelines to guide treatment and anesthesia management in such patients. Case presentation In this report, we present a 38-year-old woman with occasional dizziness and headache diagnosed as multiple cerebral fusiform aneurysms, in whom transthoracic echocardiography revealed a mass attached to the interatrial septum in the left atrium. Myxoma resection was performed in fast track cardiac surgery pathway without neurological complications, and no intervention was carried out on the cerebral aneurysms. She was discharged home 6 days after the procedure for followed-up. Furthermore, we reviewed and analyzed the literature in the PubMed and Google Scholar databases in order to conclude the optimal treatment in such cases. Conclusions Atrial myxoma-related cerebral aneurysms are always multiple and in a fusiform shape in most occasions. Early resection of myxoma and conservative therapy of aneurysm is an optimal treatment. TEE and PbtO2 monitoring play an essential role in anesthesia management. Fast track cardiac anesthesia is safe and effective to early evaluate neurological function. Long term follow-up for “myxomatous aneurysms” is recommended. And outcome of most patients is excellent.

Abstract
Despite the huge improvement in cardiovascular care over the past several decades and the decline in cardiovascular deaths, sudden cardiac death (SCD) continues to present a nationwide health problem accounting to more than half of all deaths from cardiovascular disease. Majority of these cases are related to coronary artery disease and arrhythmias, however, a very small number of these cases are secondary to cardiac neoplasms. These neoplasms commonly present with conduction abnormalities or symptoms secondary to valvular disease such as dyspnea, orthopnea, cough and/or edema. This is a rare case of a 63-year-old gentleman who suffered sudden cardiac death secondary to a cardiac myxoma.

Abstract
BACKGROUND Cardiac myxoma is the most common primary benign tumor of the heart and it has diverse clinical presentations. It is known to embolize into systemic circulation. However, presentation with complete occlusion of the aorta is uncommon. CASE REPORT We report an 18-year-old female who presented to the emergency department with features of acute bilateral limb ischemia. Arterial Doppler ultrasonography showed infrarenal aortic occlusion. A bedside cardiac ultrasound was done in the emergency department which clinched the diagnosis of atrial myxoma. Complete surgical excision of the tumor and subsequent histopathologic examination confirmed the diagnosis of atrial myxoma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This report puts emphasis on the fact that atrial myxoma, though rare, may be considered as a source of embolism in patients presenting with acute limb ischemia. The importance of bedside ultrasonography for early diagnosis in such presentations is also highlighted.

Abstract
BACKGROUND Cardiac myxomas are the most frequent cardiac tumors. Although histologically benign, in some cases myxomas may be lethal, due to impairment of cardiac dynamics and their thromboembolic potential. The study aimed to assess the clinical presentation of cardiac myxomas and their correlation with echocardiographic features and to describe the perioperative results and long-term outcome of surgically treated patients. METHODS A prospective study of 53 patients with cardiac myxomas who were operated at Hospital Argerich, followed clinically and with echocardiography from 1993 until 2013. All patients underwent echocardiographic studies. RESULTS The patient's mean age was 53 ± 16 years (62.3% were women). The most common findings were dyspnea followed by embolic events. Most tumors were localized in the left atrium (77.4%), mainly in the fossa ovalis (63%). Mean size of the tumors was 4.76 x 3.50 cm. Tumors were generally mobile (88%) and went beyond the valve plane, causing mild mitral or tricuspid valve obstruction (58%) and dilation of the respective atrial chamber. Patients whose tumors were obstructive had higher pulmonary artery systolic pressures (50 vs 33 mmHg p < 0.01). According to the echocardiographic appearance 67% of tumors had a smooth surface and the remaining 32% had a villous surface. All patients with embolic manifestations had tumors with a villous surface. CONCLUSIONS Clinical presentation relates to the ultrasound characteristics of myxomas. Smooth tumors are larger, occur with obstructive symptoms, and benefit from an elective surgery, whereas villous myxomas entailed a high embolic risk and require prompt surgical treatment.

Abstract
Background Myxomas account for approximately half of all primary cardiac neoplasms. Most occur in the left atrium and only rarely are attached to the mitral valve, with just over 30 such cases reported in the literature. These neoplasms can manifest with a combination of obstruction of blood flow, systemic embolization, and constitutional symptoms. Case Description We present a case of a 32-year-old African American man presenting at an emergency department with symptoms of a transient ischemic attack. Transesophageal echocardiography identified a mass originating from the posterior leaflet of the mitral valve. The mass was surgically resected and histologically classified as a myxoma. He remained asymptomatic during the course of 5-year surveillance. Conclusions Few similar cases have been described in the literature. Here we present a review of the diagnosis and surgical management of this rare presentation for mitral valve myxoma.

Abstract
Myxomas are the most common benign cardiac neoplasms in adults. The vast majority of cardiac myxomas arise from the left atrium near the fossa ovalis of the intra-atrial septum. There have been reports of myxomas arising from the ventricles accounting for about 5% of cases. In our literature review, we have found 55 reported cases of myxomas originating from the mitral valve reported in the adult population dating back to 1871. The majority of these cases presented with embolic complications or syncope. We present an incidental mitral valve myxoma which we excised in efforts to prevent debilitating complications.

Abstract
Left atrial myxoma is the common benign tumor of heart. Coronary arteries may supply these tumor. Considering the vascular nature of the tumor, acquired coronary cameral fistula(CCF) can be a possibility postexcision of the left atrial myxoma. Here, we discuss a case of 53-year-old female patient, who developed acquired CCF, following excision of the tumor and the role of transesophageal echocardiography intraoperatively in diagnosis.

Abstract
BACKGROUND Cardiac myxomas are the most frequent primary benign intracardiac tumors. We reviewed our 27-year experience to evaluate factors associated with an embolism in patients with cardiac myxomas and their long-term outcomes. METHODS A retrospective review identified 99 patients with cardiac myxomas between 1985 and 2012. Tumors were divided into two groups based on their gross external features. Tumors with a smooth regular border and a solid consistency were classified as solid; papillary myxomas were characterized by an irregular and gelatinous exterior with friable, soft consistency. The patients were classified into embolic and non-embolic groups to focus on embolic events. RESULTS Mean age at surgery was 49.8 ± 16 years. There were 92 left atrial myxomas (92.9%). Embolization was observed in 25 patients (25.3%) before surgery. Three variables were associated with an embolic event, small tumor size (odds ratio [OR] = 4.36 P = 0.037 confidence interval [CI] 95% 0.534-0.980), atrial fibrillation (OR = 10.119 P = 0.001 CI 95% 0.021-0.397), and papillary-type pathology (OR = 11.544 P = 0.001 CI 95% 0.033-0.399). Tumor pathology or the presence of embolization prior to surgery had no effect on operative mortality or long-term survival. CONCLUSIONS Embolization of cardiac myxomas is more likely to occur in papillary-type tumors, that are smaller in size and in patients presenting with preoperative atrial fibrillation. However, the presence of embolization at the time of surgery does not increase operative morbidity or mortality or affect long-term survival.

Small, smooth, nonmobile cardiac myxoma detected by transesophageal echocardiography following recurrent cerebral infarction: a case report. J Med Case Rep 2017; 11:131.

Abstract
Background Cardiac myxoma is known to cause repeated events of cerebral embolism. Soft and irregularly shaped myxomas with high mobility are associated with a higher occurrence of cerebral embolism. In contrast, nonmobile cardiac myxomas with a round regular shape are rarely considered to be a cause of cerebral embolism. In this case, we present a patient with recurrent cerebral embolism associated with a small and nonmobile cardiac myxoma of round regular shape. Case presentation A 76-year-old Japanese man presented to our hospital with weakness in his right upper extremity. He had a history of right frontal lobe infarction in the previous month. T2-weighted magnetic resonance imaging revealed an area of hyperintensity in the left precentral gyrus, indicating acute cerebral infarction. Transthoracic echocardiography revealed normal left ventricular function and no abnormalities. However, transesophageal echocardiography showed a small and nonmobile left atrial tumor with round regular shape attached to the ostium secundum of the atrial septum. Based on these findings, we diagnosed recurrent cerebral infarction due to embolization caused by left atrial myxoma, and cardiac tumor extraction was performed on hospitalization day 36. The excised tumor measured 0.6 × 0.6 × 0.5 cm and was diagnosed as cardiac myxoma by histologic examination. Conclusions Even small and nonmobile cardiac myxomas with a round regular shape may cause recurrent cerebral infarction. The diagnosis of this type of atrial myxoma is elusive and transesophageal echocardiography was an effective method of detection. In a clinical situation, this type of cardiac myxoma may be overlooked as a cause of cerebral infarction.

Abstract
We report 2 patients with left atrial (LA) myxoma with associated severe left ventricular (LV) dysfunction. Both presented with progressive effort intolerance without a history suggestive of acute coronary event. LA myxoma was diagnosed by transthoracic echocardiography, which also detected severe systolic dysfunction and LV dilatation. Regional wall motion abnormality and thinning were absent. Coronary angiograms also showed no occlusive disease, but distal ectasia was seen in 1 patient. Metabolic and endocrine causes of reversible LV dysfunction were excluded. Cardiac function improved following surgery for myxoma in 1 patient. LV dysfunction, thus far, has not been directly attributed to myxoma. Coronary embolization leading to myocardial infarction and coexisting coronary atherosclerosis are the recognized methods by which LV dysfunction manifests in myxoma. Our report suggests the possibility of reversible severe global LV dysfunction due to cardiodepressant effect of myxoma through as yet unclear mechanisms.

Abstract
Primary cardiac tumors are extremely rare and constitute only about 5% of all cardiac tumors. Cardiac myxomas are noncancerous primary tumors of the heart and constitute about of 50% of all primary heart tumors. Left-sided atrial myxomas are more common than right-sided atrial myxomas. Atrial myxomas can lead to a triad of complications. The most common symptoms are associated with obstruction due to the size and location of the tumor. The next most common symptoms are associated with pulmonary and systemic embolization. Patients may also present with constitutional symptoms. Diagnosis is made via means of transesophageal echocardiography and magnetic resonance imaging. Early diagnosis and surgical resection remain the treatment of choice to prevent complications. Patients usually have a good prognosis after resection.

Abstract
The purpose of this study was to present 11 patients operated on owing to rare forms of peripheral arterial embolism at the Institute for Cardiovascular Diseases of the Serbian Clinical Center over a period of 20 years. Three patients were operated on owing to a foreign body embolism, two owing to a septic embolism, three owing to emboli that originated from malignant tissues, two owing to an embolization from cardiac myxoma, and one owing to an embolism from a myxomatous atrial septal defect. The preoperative evaluation included clinical examination, laboratory findings, and electrocardiography; in the majority of cases, ultrasonography and angiography were performed. Surgical treatment included foreign body extraction in three cases; thromboembolectomy in seven cases, and artery resection and saphenous graft interposition in one patient with septic embolism. In addition, three cardiosurgical procedures were done: aortic valve replacement in the patient with a septic embolism and tumor excision in patients with atrial myxoma. In addition to the usual clinical signs of acute limb ischemia, in the rare forms of arterial embolism, the presence of certain uncommon clinical symptoms was also observed. The early results of vascular surgical treatment were very good in all patients. Further follow-up revealed a poor prognosis in patients with malignant arterial embolism.

Abstract
BACKGROUND Risk factors for embolism and recurrence of primary cardiac myxoma are not well established. This study aimed to assess the risk factors for embolism and recurrence of cardiac myxoma, as well as the survival of the patients. METHODS The medical records of 207 consecutive patients treated for primary cardiac myxoma between September 1988 and October 2014 were retrospectively analyzed. All diagnoses were pathologically confirmed. Data were collected to identify the risk factors influencing the prognosis. RESULTS Mean age at surgery was 44.2 ± 15.8 years. Operative mortality (within 30 days of the surgery) occurred in seven patients. Mean follow-up was 9.35 ± 6.55 years. Embolism occurred in 32 (15.5 %) patients before surgery. Multivariate analysis indicated that small (≤ 4.5 cm) myxoma (OR = 5.14; 95 % CI, 2.30-11.94; P < 0.0001) and soft, gelatinous myxoma (OR = 5.84; 95 % CI, 1.91-25.61; P = 0.001) were independently associated with the occurrence of embolism. Ten patients experienced recurrences. After excluding the patients who died within 30 days of surgery, survival was 92.7 % at 10 years. Age, sex, tumor size, cardiopulmonary bypass duration, aortic cross clamp duration, tumor appearance, and pre-operative embolism were not associated with early mortality. Multivariate analysis showed that multicentric myxomas were independently associated with recurrence (OR = 9.45, 95 % CI, 2.15-41.3, P = 0.004). CONCLUSIONS The surgical resection of primary cardiac myxoma is associated with excellent long-term survival. Tumors ≤ 4.5 cm and soft tumors were independent risk factors for embolism. Multicentric cardiac myxoma was an independent risk factors for recurrence of myxoma.

Abstract
A 64-year-old man developed right arm weakness and dysarthria, and was admitted to our hospital. Diffusion-weighted magnetic resonance imaging of the brain showed a high intensity area in the frontal lobe. T2*-weighted images showed multiple spotty low intensity lesions in bilateral cerebral hemispheres, mimicking cerebral microbleeds. Cerebral angiography showed multiple aneurysms in the anterior, middle, posterior cerebral arteries and cerebellar arteries. Transthoracic echocardiography revealed a floating structure in the left atrial chamber, indicating cardiac myxoma. We diagnosed cardioembolic ischemic stroke due to left atrial myxoma. Cardiac surgery for excision of a left atrial myxoma was performed on the 3rd hospital day. Multiple aneurysms should be taken into account for differential diagnosis in patients with cardiac myxoma and with atypical spotty low intensity on T2*-weighted images.

Abstract
Myxoma is a common benign cardiac tumor that may rarely cause an acute myocardial infarction. A 77-year-old woman was admitted to our hospital with chest pain. Electrocardiography showed an ST elevation in leads V3-6. Transthoracic echocardiography revealed an ovoid mass with fragmentation in the left atrium and hypokinesia of the left ventricular apex. Coronary angiography indicated the presence of a coronary embolism that was suspected to be from the left atrial mass. The mass was removed by emergency surgical resection to avoid a further systemic embolism and was diagnosed pathologically as a myxoma. The patient was discharged after 13 days with no complications.

Abstract
Cardiac myxoma is the most common cardiac neoplasm. In the majority of cases, it is isolated (non-syndromic) and located in the left atrium. In up to 10% cases, it is seen in syndromic association with the Carney complex where it is encountered in younger patients, with atypical and multiple locations, such as the right atrium or ventricles, and carries a high risk of recurrence. Imaging is pivotal in the diagnosis, management guidance and surveillance. Surgical excision is the established definitive treatment. Further research should address management strategies in incidentally discovered small myxomas in asymptomatic patients and the role of genetic testing and screening in syndromic myxomas.

Abstract
Introduction The aim of this study was to determine the factors associated with postoperative atrial fibrillation (AF) in patients with left atrial (LA) myxoma. Methods Thirty-six consecutive patients with LA myxoma (10 men, mean age: 49.3 ± 15.7 years), who were operated on between March 2010 and July 2012, were included in this retrospective study. Pre-operative electrocardiograms and echocardiographic examinations of each patient were reviewed. Results Postoperative AF developed in 10 patients, whereas there was no evidence of paroxysmal AF after resection of the LA myxoma in the remaining 26 patients. The patients who developed AF postoperatively were significantly older than those who did not develop AF (median: 61.5 vs 46 years; p = 0.009). Among the electrocardiographic parameters, only P-wave dispersion differed significantly between postoperative AF and non-AF patients (median: 57.6 vs 39.8 ms, p = 0.004). Logistic regression analysis revealed P-wave dispersion (OR: 1.11, 95% CI: 1.003–1.224, p = 0.043) and age (OR: 1.13, 95% CI: 1.001–1.278, p = 0.048) as independent predictors of postoperative AF in our cohort of patients. Conclusions P-wave dispersion is a simple and useful parameter for the prediction of postoperative AF in patients with LA myxoma.

Abstract
BACKGROUND Cardiac myxomas are the most common benign intracardiac tumors. We studied the clinical presentation of cardiac myxomas, their morbidity, mortality and recurrence rate following surgery at our institution over a period of four years. METHODS During August 2008 to November 2012, a total of 12023 cardiac surgeries were performed. Amongst these, 50 patients (12 males, 38 females) underwent complete removal of primary or recurrent intracardiac myxomas. Complete tumor excision with a cuff of interatrial septum followed copious saline irrigation of the cardiac chambers was performed in each case. RESULTS Forty six patients survived the surgery of which 43 are being followed up at regular intervals for development of recurrence. Myxomas constituted 0.41% of the total cardiac surgeries at our institute. Most of them were noted in the fourth decade. The commonest location was left atrium (74%) followed by right atrium (22%). Only one patient had a myxoma in the right ventricle. Forty six patients (92%) survived the surgery. CONCLUSION Cardiac myxoma excision account for a very small percentage of cardiac procedures. Immediate surgical treatment is indicated in all patients. Cardiac myxomas can be excised with a low rate of mortality and morbidity.

Abstract
Cardiac myxomas are the most common type of benign cardiac tumors and most of them occur in the left atrium but the biatrial myxoma is uncommon. We present a rare case of giant biatrial myxoma nearly obstructing the orifice of the inferior vena cava. A 58-year old woman presented with exertional dyspnea and intermittent chest discomfort. The non-pedunculated tumor involved most of the interatrial septum and extended from the orifice of the inferior vena cava to the displaced mitral annulus and the lower left pulmonary vein. The resected specimen weighed 76 gram and measured 80 × 40 × 30 mm. She did not complain of dyspnea or show any sign of recurrence by echocardiography during the 2-year follow-up period.
