RESUMO
Cardiac myxoma is extremely rare in children. However, if not treated immediately, it may cause varying symptoms until sudden death. A-9-years old male Javanese child was brought to the emergency department of Prof. Soekandar General Hospital, Mojokerto with progressive dyspnoea since one month which got worse in the left decubitus position. There was no significant past medical history. Physical examination revealed hypotension, mitral stenosis, tricuspid regurgitation, and pulmonary congestion. Transthoracic echocardiography revealed a round pedunculated 3x3.3 cm mass in the Left Atrium that swingingly moved to the Left Ventricle during diastole. This was diagnosed provisionally as Myxoma with a differential of thrombus. After stabilization, he was referred to a tertiary hospital for emergency excision. Histopathology confirmed the myxoma. There were no symptoms and activity limitations during the 6 months follow-up. To the best of our knowledge, this is the first paediatric cardiac myxoma with Acute Heart Failure symptoms reported in Indonesia. Echocardiography is imperative for diagnosing myxoma. Appropriate and timely management results in an excellent outcome.

Primary cardiac angiosarcoma is a rare, aggressive malignancy that commonly metastasizes to various organs. The presenting symptoms are typically nonspecific, so a comprehensive examination is required to confirm the diagnosis promptly. This case report describes the presentation of an older patient with a history of neoplasms. Echocardiography and biopsy were performed, but despite surgical intervention to resect a large right atrial mass, the patient died. A final diagnosis of primary angiosarcoma was made based on the resected specimen.

Undifferentiated pleomorphic cardiac sarcomas are extremely rare, highly malignant mesenchymal cardiac neoplasms typically presenting in the sixth decade of life. Here, we have reported a rare case of undifferentiated pleomorphic cardiac sarcoma presenting with dyspnea in a young male. On further evaluations, a large, ill-defined, multilobulated mass was observed in left atrium (LA) with encasement of left circumflex artery, attachment to mitral valve annulus, and invasion through LA wall and pericardium.
RESUMO
BACKGROUND: Surgical resection remains the mainstay of treatment for cardiac sarcoma, a rare but lethal disease. Achieving complete removal of a large-sized left ventricular sarcoma remains a challenge even with various surgical approaches that have been employed. CASE PRESENTATION: We present a case of a 74-year-old woman with shortness of breath who underwent surgical removal of a primary cardiac sarcoma, measuring 6 × 3.5 × 3 cm, attached to the septum of the left ventricle and caused sub-aortic valve obstruction. Transaortic approach was chosen and the access to this entire huge mass was enabled by using interim partial resection which created a space for further dissection and subsequent deeper endoscopic views. The further dissection was finally able to be advanced on the apex, and the residual mass was completely resected with gross tumor-free margins. CONCLUSION: Interim partial resection and endoscopic guidance can highly facilitate the transaortic removal of even large left ventricular sarcomas.

INTRODUCTION: Primary cardiac myxomas are rare tumors. Concurrent valvular lesion is a common finding on evaluation which is thought to be due to annular dilatation secondary to tumor movement across the valve, functional obstruction across the valve, and severe pulmonary hypertension secondary to chronic obstruction. A common belief among surgeons is that excision of myxoma leads to abatement of symptoms, and further valve intervention may not be warranted. METHODS: A 10-year retrospective descriptive study was designed to analyze patients who underwent excision of cardiac myxoma at our center. Data was analyzed regarding presenting features, echocardiographic findings of myxoma and valve morphology, intraoperative assessment, and postoperative outcome with/without valve repair/replacement in all patients. RESULTS: A total of 22 patients underwent surgery for myxoma. Six patients underwent successful mitral valve repair with ring annuloplasty, two had moderate mitral regurgitation, three had severe mitral regurgitation, and one patient had no mitral regurgitation on preoperative assessment, but moderate mitral regurgitation was found intraoperatively. Four of these patients had no residual mitral regurgitation in follow-up period while two had mild residual mitral regurgitation. One patient had severe mitral stenosis of concurrent rheumatic etiology and successfully underwent mitral valve replacement. CONCLUSION: Cardiac myxomas are rare benign tumors commonly associated with mitral valve insufficiency. Mitral valve should be assessed intraoperatively after excision of mass as preoperative assessment might often be insufficient. Concomitant mitral valve intervention might be needed with a case-specific tailored approach, and mitral valve repair with ring annuloplasty offers best surgical outcome in such cases.

BACKGROUND: Malignant primary cardiac tumors are infrequent and can lead to an unfavorable prognosis if not identified and treated promptly. Early detection and prompt treatment of malignant primary cardiac tumors are crucial for a better prognosis. This article presents a case of primary cardiac leiomyosarcoma and reviews the literature on this topic. CASE PRESENTATION: Female patient that developed recurrent pericardial effusion and hemodynamic instability caused by a cardiac tumor, later identified as leiomyosarcoma. Multidisciplinary treatment was administered to the patient. CONCLUSIONS: The initial approach to this type of pathology should include multimodality imaging to establish a prompt diagnosis leading to complete standard treatment, to minimize risks to the patient's heart function which may include resection with complete margins of the neoplasm, otherwise the prognosis may be poor.
RESUMO
Objective:To investigate the clinicopathological features, mutation, therapeutic efficacy and the factors influencing the prognosis of patients with cardiac diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 11 cardiac DLBCL patients in Ruijin Hospital of Shanghai Jiao Tong University School of Medicine from January 2016 to October 2020 were retrospectively analyzed. NovaSeq sequencing platform was used to detect gene mutations in 5 patients, and bioinformatics analysis of sequencing data was conducted through public database to identify the mutation sites of pathogenic genes. Kaplan-Meier method was used to analyze the progression-free survival (PFS) and the overall survival (OS). Univariate Cox proportional risk model was used to analyze the influencing factors of prognosis.Results:Among 11 patients with cardiac DLBCL, 5 were male and 6 were female. The age [ M ( Q1, Q3)] was 61 years (45 years, 70 years). All 11 patients were non-germinal center B-cell (non-GCB) type. There were 2 primary cases and 9 secondary cases; 9 cases with Ann Arbor stage of Ⅲ-Ⅳ, 10 cases with increased lactate dehydrogenase (LDH) and 9 cases with international prognostic index (IPI) score equal to or higher than 3 scores. Among 11 patients, 9 cases received a first-line treatment based on the R-CHOP (rituximab, cyclophosphamide, epirubicin/doxorubicin hydrochloride liposomes, vincristine and prednisone) regimen, of which 8 patients achieved complete remission (CR), and 1 patient achieved stable disease (SD); 1 patient received IR2 (ibrutinib + rituximab + lenalidomide) treatment regimen and achieved SD, and 1 patient received supportive treatment only and achieved progression of the disease. The follow-up time was 39.9 months (25.6 months, 57.3 months). The 3-year PFS rate and 3-year OS rate of 11 patients was 54.5%, 77.9 %, respectively. Univariate Cox regression analysis showed that gender, B symptoms, Ann Arbor stage, LDH level, number of extranodal lesions, IPI score were not correlated with PFS and OS of patients (all P > 0.05). Among 5 cases undergoing gene detection, KMT2D mutations and PIM1 mutations were detected in 2 cases,respectively. Interestingly, KMT2D mutations were only found in secondary cardiac DLBCL patients (2/3), while PIM1 mutations were only detected in primary cardiac DLBCL patients (2/2). Conclusions:Most cardiac DLBCL patients are non-GCB type and have advanced clinical stage, while may benefit from R-CHOP treatment regimen. PIM1 and KMT2D are the commonly mutated genes in cardiac DLBCL.

RESUMO
ABSTRACT Objective: Pediatric cardiac tumors are rare and, among them, 90% are benign. Cardiac fibroma is the second most frequent tumor, after rhabdomyoma. The objective of this study is to report a case of cardiac fibroma diagnosed incidentally in a patient admitted with acute viral bronchiolitis. Case description: A 5-month-old male infant was admitted to the pediatric emergency department with acute viral bronchiolitis requiring hospitalization. He presented a detectable respiratory syncytial virus in oropharyngeal swab, blood test with lymphocytosis and a chest radiography revealed cardiomegaly. Further cardiologic testing was performed detecting elevation of cardiac biomarkers, an electrocardiogram with alteration of left ventricular repolarization and echocardiogram with a heterogeneous mass in the left ventricular, with areas of calcification. A chest angiotomography suggested rhabdomyosarcoma or cardiac fibroma and a magnetic resonance showed a mass, with characteristics suggesting fibroma. The final diagnosis was made after two cardiac catheterizations for biopsy of the lesion, confirming cardiac fibroma by anatomopathological examination. Because the patient had moderate to severe systolic dysfunction, he was submitted to heart transplant. Comments: One third of cardiac fibromas are asymptomatic, generally diagnosed late through tests ordered for other reasons. The gold-standard test for definitive diagnosis is biopsy. Cardiac fibroma usually does not present spontaneous regression and, in most cases, partial or total surgical resection is necessary. When tumors are unresectable, heart transplantation should be indicated. It is essential to have detailed characterization of the cardiac mass to establish the most appropriate therapeutic approach for each patient.
RESUMO Objetivo: Tumores cardíacos pediátricos são raros e, entre eles, 90% são benignos. O fibroma cardíaco é o segundo mais frequente, após o rabdomioma. O objetivo deste trabalho é relatar um caso de fibroma cardíaco, cujo diagnóstico foi incidental em um paciente internado por bronquiolite viral aguda. Descrição do caso: Lactente do sexo masculino com cinco meses foi atendido em um pronto atendimento pediátrico com quadro de bronquiolite viral aguda, necessitando de hospitalização. Em exames complementares, apresentou vírus sincicial respiratório detectável, hemograma com linfocitose, além de radiografia de tórax com cardiomegalia. Em investigação cardiológica, as enzimas cardíacas encontravam-se elevadas, o eletrocardiograma apresentava alteração de repolarização de parede lateral de ventrículo esquerdo e o ecocardiograma demonstrou massa heterogênea em ventrículo esquerdo, com áreas de calcificação. A angiotomografia de tórax sugeriu rabdomiossarcoma ou fibroma cardíaco e a ressonância magnética demonstrou massa cuja localização e características sugeriram fibroma. O diagnóstico foi conclusivo após dois cateterismos para biópsia da lesão, confirmando fibroma cardíaco pelo anatomopatológico. Em razão da disfunção sistólica moderada a grave, o paciente foi submetido a transplante cardíaco. Comentários: Um terço dos fibromas cardíacos é assintomático, geralmente diagnosticado tardiamente por meio de exames solicitados por outro motivo. O padrão-ouro para o diagnóstico definitivo é a biópsia. O fibroma cardíaco não costuma apresentar regressão espontânea, sendo submetido, na maioria dos casos, a ressecção cirúrgica parcial ou total. Nos tumores irressecáveis, o transplante cardíaco deve ser indicado. A caracterização detalhada da massa cardíaca é fundamental para traçar a conduta terapêutica mais adequada para cada paciente.
RESUMO
Resumo Fundamento: Seguimento de coorte retrospectiva de 30 anos que se aproxima da história natural dos tumores cardíacos diagnosticados no feto uma vez que nenhum caso foi submetido à interrupção da gestação. Objetivo: Avaliar a morbidade e mortalidade perinatal e em longo prazo em fetos com diagnóstico de tumor cardíaco. Como objetivo secundário avaliar os fatores que influenciaram os resultados perinatais e pós-natais. Método: Estudo de coorte retrospectiva envolvendo 74 gestantes com diagnóstico ecocardiográfico fetal de tumor cardíaco acompanhadas em dois serviços de referência no período de maio de 1991 a novembro de 2021. Foi realizada análise descritiva dos dados por meio de frequências absolutas (n) e relativas (%), mediana e intervalos interquartis. Para avaliar a associação entre as características ecocardiográficas e as manifestações clínicas com os resultados perinatais e pós-natais, foi aplicado o teste exato de Fisher. O cálculo da sobrevida global foi realizado pelo método de Kaplan-Meier e a comparação de curvas pelo teste de log-rank. O tempo de seguimento, calculado em meses, foi definido a partir da data de alta do hospital à data do status atual (vivo/censura ou óbito). O nível de significância considerado foi de 5% (p<0,05). Resultados: o rabdomioma é o tipo mais frequente (85%) de tumor cardíaco; apresenta alta morbidade (79,3%) e mortalidade geral de 17,4%; a presença de hidropisia fetal preditiva de óbito. Conclusão: A presença de hidropisia fetal teve impacto na mortalidade, sendo fator importante para aconselhamento e estabelecimento de prognóstico. A maioria dos óbitos ocorrem antes da alta hospitalar.
Abstract Background: This was a 30-year retrospective cohort study that approximates closely to the natural history of cardiac tumors diagnosed in the fetus, since there was no case of pregnancy interruption Objective: To assess morbidity and mortality in the perinatal period and at long term in fetuses diagnosed with cardiac tumor. Our secondary objective was to assess the evaluating factors of perinatal and postnatal results. Methods: This was a retrospective cohort study with 74 pregnant women with an echocardiographic diagnosis of fetal cardiac tumor at two referral centers between May 1991 and November 2021. A descriptive analysis was performed, and data were expressed as absolute (n) and relative (%) frequencies, median and interquartile range. Fisher's exact test was used to evaluate the association of echocardiographic characteristics and clinical manifestations with perinatal and postnatal results. Global survival was calculated using the Kaplan-Meier method and the curves were compared by the log-rank test. The time of follow-up, calculated in months, corresponded to the time elapsed from hospital discharge to current status (survived/ censoring or death). The level of significance was set at 5% (p<0.05). Results: Rhabdomyoma is the most common type of cardiac tumor (85%), with a high morbidity (79.3%) and overall mortality of 17.4%. The presence of fetal hydrops was a predictor of death. Conclusion: The presence of fetal hydrops had an impact on mortality, and hence is an important factor in counselling and determining the prognosis. Most deaths occurred before hospital discharge.
RESUMO
Objective To observe the value of multimodal imaging for diagnosis of cardiac space-occupying lesions.Methods Data of 70 patients with cardiac space-occupying lesions who underwent echocardiography and cardiac CT(CCT)were retrospectively analyzed,among them 35 also underwent cardiac MRI(CMRI).The value of multimodal imaging for diagnosis of cardiac space-occupying lesions were explored according to the results of surgical pathology or clinical diagnosis.Results Among 70 cases,benign tumors were confirmed by surgical pathology in 43 cases,while malignant tumors were confirmed by surgical pathology in 3 cases and clinically diagnosed in 1 case.Meanwhile,non-tumor-occupying lesions were clinically diagnosed in 23 cases,all obviously shrunken after treatments.Among 70 cases,echocardiography correctly diagnosed 57 cases,misdiagnosed 8 cases and unclearly diagnosed 5 cases,with diagnostic accuracy rate of 81.43%(57/70).CCT correctly diagnosed 63 cases,misdiagnosed 4 cases but missed 3 cases,with diagnostic accuracy rate of 90.00%(63/70).CMRI outcomes in all 35 cases were consistent with surgical pathologic results,with diagnostic accuracy rate of 100%(35/35).Conclusion Multimodal imaging might provide objective evidences for diagnosis and treatment of cardiac space-occupying lesions.
RESUMO
Fundamento. Las masas y quistes cardíacos son entidades bien conocidas, cuya reducida prevalencia y sintomatología inespe-cífica dificultan su diagnóstico. El objetivo del estudio fue ca-racterizar el cuadro de los pacientes afectos en nuestro medio para orientar futuros diagnósticos.Metodología. Estudio descriptivo de los pacientes intervenidos de tumores y quistes cardíacos entre 2002 y 2022 mediante la búsqueda en el registro del Servicio de Cardiología y Cirugía Cardíaca de la Clínica Universidad de Navarra (Pamplona, Es-paña). Se recogieron variables sociodemográficas, clínicas, his-tológicas y quirúrgicas.Resultados. Se identificaron 13 pacientes, la mayoría (76,92%) mujeres, con media de edad 63,08 años (DE: 15,17). El 92,31% de los pacientes tenían al menos un factor de riesgo cardiovascular, siendo los más prevalentes un IMC ≥25 kg/m2 y la hipertensión arterial (61,54% y 53,85%, respectivamente). El tipo de masa car-díaca más frecuente fue el mixoma (69,23%). El 46,15% de masas cardiacas fueron hallazgos incidentales; el síntoma más frecuen-te fue la disnea (53,85%) y el 30,77% de los pacientes se encontra-ban asintomáticos. . La prueba de imagen más empleada para en el diagnóstico fue la ecocardiografía transtorácica Doppler color (69,23%). La concordancia entre los diámetros medios precirugía y postcirugía resultó muy alta (CCI = 0,807, IC95%: 0,450-0,943).Conclusiones. Se describieron los cuadros de los pacientes, apor-tando información poco descrita en la literatura, como los facto-res de riesgo cardiovascular más frecuentes en estas entidades. Se describieron un caso de leiomiosarcoma cardíaco y un caso de sarcoma intimal del tronco pulmonar, dos tipos de tumores extremadamente raros de los que existen pocos casos descritos (AU)
Background. Masses and cysts in the heart are well-known entities, but their low prevalence and non-specific symptoms makes the diagnosis difficult. We aimed to characterize the fea-tures of these entities in our environment.Methods. We carried out a search of patients who underwent surgery for tumors and cysts in the heart between 2002 and 2022 in the registry of the Department of Cardiology and Car-diac Surgery of Clínica Universidad de Navarra (Pamplona, Spain). Sociodemographic, clinical, histological, and surgical variables were collected.Results. We identified 13 patients; mean age was 63.08 ± 15.17 years, 76.92% were female and 92.31% had at least one car-diovascular risk factor, e.g., BMI ≥ 25 kg/m2 and high blood pressure (61.54% and 53.85%, respectively). The most com-mon type of cardiac tumors were myxomas (69.23%). Around half (46.15%) were incidental; the most frequent symptom was dyspnea (53.85%); 30.77% of the patients were asymptomatic. The most commonly used imaging technique for the diagno-sis was transthoracic Doppler echocardiography (69.23%). The agreement between the mean diameters before and after sur-gery was very high (ICC = 0.807, 95%CI: 0.450-0.943).Conclusions. We describe the features of masses and cysts in the heart (77% female patients) and provide information scarcely available in the literature, e.g., the most frequent car-diovascular risk factors for this population. A case of cardiac leiomyosarcoma and a case of intimal sarcoma of the pulmo-nary trunk are described, two extremely rare tumors for which there are few described cases (AU)

Resumo Os últimos meses de 2019 foram marcados pelo surgimento de uma nova pandemia, denominada "COVID-19". Desde então, essa infecção e suas complicações têm sido a prioridade de profissionais de saúde, com muitos sintomas atribuídos às suas apresentações precoces e tardias. Até o momento, outras doenças, mesmo em situações fatais, têm sido negligenciadas ou diagnosticadas incorretamente devido à atribuição dos sintomas do paciente à presença da infecção por COVID-19. Apresentamos aqui um caso de angiossarcoma cardíaco, em um menino que, cerca de 2 meses antes, havia sido infectado com COVID-19. Dado o histórico de infecção, a abordagem inicial foi o manejo da miopericardite pós-COVID-19. No entanto, o quadro do paciente piorou, exigindo reavaliação por multimodalidades com maior precisão. Por fim, o paciente foi diagnosticado com um tumor cardíaco. Este artigo procura enfatizar a importância da atenção a outras doenças e condições fatais na era COVID-19, com ênfase em evitar diagnósticos incorretos de outras doenças.
Abstract The final months of 2019 saw the emergence of a new pandemic termed "COVID-19". Since then, this infection and its complications have been the priority of healthcare providers, with many symptoms attributed to its early and late presentations. Thus far, other diseases, even fatal situations, have been overlooked or misdiagnosed due to the attribution of patient symptoms to the presence of COVID-19 infection. We herein present a case of cardiac angiosarcoma in a young boy who had previously become infected with COVID-19 about two months earlier. Given the history of infection, the initial approach was post-COVID-19 myopericarditis management. However, the patient's condition worsened, necessitating reevaluation via multimodalities with higher precision. Ultimately, the patient was diagnosed with a cardiac tumor. This article seeks to underscore the significance of taking heed of other diseases and fatal conditions during the COVID-19 pandemic with an emphasis on avoiding misdiagnosing other diseases.
RESUMO
ABSTRACT Primary cardiac tumors are rare, with an incidence between 0.0017 and 0.19%, and are asymptomatic in up to 72% of cases. Approximately 75% of tumors are benign, and nearly 50% of these are myxomas. Concerning location, 75% of myxomas are in the left atrium, 15 to 20% in the right atrium, and more rarely in the ventricles. The finding of cardiac myxomas usually implies immediate surgical excision to prevent embolic events and sudden cardiac death. Reports with documented growth rate are rare, and the actual growth rate remains a controversial issue. We report the rapid growth rate of a right atrial myxoma in an oligosymptomatic 69-year-old patient, with negative previous echocardiographic history in the last two years, who refused surgery upon diagnosis, enabling monitoring of myxoma growth.

Abstract Introduction: Lymphomas arising from cardiac myxomas represent a particularly rare pathology, with only few cases reported in the literature. Case presentation: We report a complete excision of a malignant lymphoma arising from a cardiac myxoma in a 44-year-old female patient. The myxoma presented like a floating mass within the left atrium with a maximum diameter of 3.5 cm. The clinical post-operative period was uneventful and the patient was dismissed on the 6th post-operative day. Conclusion: This case reinforces the concept of radical excision of cardiac neoplasms.
RESUMO
Objective:To investigate clinicopathological and magnetic resonance imaging (MRI) characteristics of pediatric cardiac tumors.Methods:The clinical, pathological and MRI data of 7 patients with pediatric cardiac tumors confirmed by pathological examination in Children's Hospital of Chongqing Medical University from February 2012 to December 2016 were retrospectively analyzed.Results:There were 3 males and 4 females with first diagnosis age ranging from 1 month to 3 years. As for clinical presentation, most cases were featured with cardiac murmur and enlarged cardiac boundary; only 1 case had acute cerebral infarction, and 1 case did not show any abnormal performance. Pathological findings showed that 6 cases of benign tumors (including 2 cases of fibroma, 1 case of rhabdomyoma, 1 case of myxoma, 1 case of lipoma and 1 case of hemangioma), 1 case of malignant tumor (primitive neuroectodermal tumor of pericardium). MRI results showed that the signal intensity of malignant tumor was higher than that of normal myocardium in each sequence; significant differences were found in benign tumors; first-pass perfusion, cardiac cine image and late gadolinium enhancement were the most obvious.Conclusions:The clinical presentations of pediatric cardiac neoplasms are atypical. Each tumor type has pathognomonic pathological features. MRI has great advantages in the diagnosis and differential diagnosis of cardiac tumors especially for benign tumors.
RESUMO
Objective: To evaluate the safety and efficacy of catheter ablation in patients with new-onset atrial arrhythmia after surgical excision of left atrial myxoma. Methods: Nine patients with new onset atrial arrhythmia and a prior history of left atrial myxoma, who received surgical myxoma excision and catheter ablation between September 2014 and November 2019, were included in the present study. Baseline characteristics, procedural parameters during catheter ablation, severe perioperative adverse events, recurrence rate of arrhythmia and clinical prognosis were analyzed. Kaplan Meier survival analysis was used to define the maintenance rate of sinus rhythm after catheter ablation in this patient cohort. Results: Nine patients were included. The average age was (55.8 ± 9.1) years old (3 male), there were 3 patients (3/9) with paroxysmal atrial fibrillation (PAF) and 6 patients (6/9) with atrial flutter or atrial tachycardia (AFL or AT). Ablation was successful in all patients, there were no perioperative complications such as stroke, pericardial effusion, cardiac tamponade, vascular complications or massive hemorrhage. During a mean follow-up time of 40.0 (27.5, 55.5) months, sinus rhythm was maintained in six patients (6/9) after the initial catheter ablation. The overall sinus rhythm maintenance rate was 2/3. In addition, 1 out of the 3 AF patients (1/3) developed recurrence of AF at 3 month after ablation, and 2 out of the 6 AFL or AT patients (2/6) developed late recurrence of AF or AFL (19 months and 29 months after ablation), two out of three patients with recurrent AFs or AFL received repeated catheter ablation and one patient remained sinus rhythm post repeat ablation. Meanwhile, there was no recurrence of atrial myxoma, no death, stroke, acute myocardial infarction and other events during the entire follow-up period. Conclusions: Catheter ablation is a safe and feasible therapeutic option for patients with new-onset atrial arrhythmia after surgical excision of left atrial myxoma.
RESUMO
Abstract Objective: To understand the current evidence and guidelines behind the appropriate management of cardiac tumours. Methods: A comprehensive electronic literature search has been performed in major databases - PubMed, Embase, Scopus, Ovid, and Google Scholar. All articles that discussed all different forms of cardiac tumours, their clinical presentation, diagnosis, and management methods have been critically appraised in this narrative review. Results: All relevant studies have been summarized in appropriate sections within our review. Cardiac tumours are rare but can be catastrophic and life-threatening if not identified and managed on timely manner. Utilization of all the available imaging methods can be of equivocal importance, relevant to each cardiac tumour. Surgical excision is the ultimate treatment method, however histopathological results can guide the adjunct treatment. Conclusion: Early detection of cardiac tumours has significant effect on planning the method of intervention. Technological advancements and increased availability of imaging modalities have enabled earlier and more accurate detection of these tumours. Novel medical therapies, recommendations for screening, and operative techniques have all contributed to overall improving knowledge of these tumours and ultimately patient outcomes.

Background: The incidence rates of cardiac tumors are low. Aim: To report the clinical presentation of cardiac myxomas and long-term evolution after resection. Material and Methods: Review of a database of surgical patients undergoing surgical resection of a cardiac myxoma in a public hospital between 1990 and 2018. Results: Seventy-eight patients aged 53 ± 15 years (65% females) were included. The most frequent comorbidities were arterial hypertension (40.5%), hypothyroidism (15%) and diabetes mellitus (12%). The main presenting symptoms were dyspnea (33%), neurological deficit secondary to embolism (30%) and acute pulmonary edema (5%). The most common location was the left atrium, in 87%. During surgery, cardiopulmonary bypass and aortic cross-clamp times were 50.2 ± 19.6 and 33.4 ± 15.2 min, respectively. One patient died due to severe neurological involvement. Follow-up was completed in seventy-seven patients, with a mean echocardiographic follow-up time of 10.4 ± 7.7 years. Thirty-four patients were followed for more than 10 years. Six patients (7.7%) died during the follow-up and in six patients (7%) a recurrence was identified. Conclusions: Cardiac myxoma usually has nonspecific symptoms. Surgical excision offers excellent short and long-term results. Complications and recurrence rates are low in non-hereditary myxomas but obligates to perform echocardiographic follow-up for early diagnosis of recurrence.
