RESUMO
Cardiac masses are relatively rare, with a right atrial mass being even more rare. Right atrial masses pose a diagnostic dilemma owing to the diverse range of potential diagnoses, even when the clinical context and initial imaging modalities are thoroughly evaluated. A right atrial mass can have a varied etiology as it can be a physiological variant, or a neoplastic or a non-neoplastic mass with each having a separate line of management. This paper aims to highlight the etiology and the surgical outcomes of patients having a right atrial mass.
RESUMO
Sudden cardiac death is a phenomenon that affects more than 200,000 individuals annually in the United States. Among sudden cardiac deaths, only a fractionally small portion is thought to be attributable to intracardiac neoplasms. Though rarely implicated as the primary cause of death, cardiac myxomas are the most common benign neoplasms of the heart and have been known to cause death due to multifactorial embolic events, fatal arrhythmias, and frank obstructive events. In this case, a healthy, asymptomatic young male was found unresponsive in his residence. Examination of the heart at autopsy revealed dilation of the right atrium and a large, hemorrhagic, irregular, and obstructing mass arising from the right atrium, consistent with cardiac myxoma. When unusual cardiac findings are discovered at autopsy, a systematic investigation of the heart, including retaining the organ for cardiac pathology consultation, is mandatory to correctly identify the cause of death.
RESUMO
Using point of care ultrasound (POCUS) to evaluate patients with syncope in the emergency department facilitates the timely diagnosis of life-threatening pathologies. Case: A 56-year-old woman presented to the emergency department of a hospital in Bogotá, Colombia, for a syncopal episode. Vital signs, physical examination, electrocardiogram, and routine laboratory tests were normal. Cardiac POCUS was performed, which identified an echogenic mass located in the left atrium, measuring 35x28mm, which in left atrial systole appeared to occupy the entire chamber. She underwent surgical resection of the mass and histopathology revealed atrial myxoma. Conclusions: POCUS was useful in the rapid diagnosis of atrial myxoma in a woman presenting with syncope.
RESUMO
BACKGROUND: Malignant cardiac neoplasms (MCNs), both primary and metastatic, are rare with few epidemiologic studies. METHODS: This retrospective study used the Healthcare Utilization Project/Nationwide Inpatient Sample database from 2002 to 2018 to evaluate the co-occurrences with other malignancies, and mortality of MCNs in the USA. RESULTS: The data contained 7207 weighted discharges of MCN. Median patient age was 51.4â¯years, 52.29â¯% were male, in-hospital mortality was 10.51â¯%, mean cost of hospitalization was $34,280 USD. Lung, mediastinum, and airways were the most common primary cancers associated with metastatic MCN. CONCLUSIONS: MCN are rare in the USA, however they carry a high in-hospital mortality, high morbidity, and hospital cost.

Cardiac lipomas are benign primary cardiac tumors that are most often asymptomatic and diagnosed incidentally. Cardiac magnetic resonance imaging (MRI) is the imaging modality of choice when aiming to characterize these tumors. A minority of cardiac lipomas are intramyocardial, which, when combined with the much more common post-infarction fatty metaplasia, makes diagnosing these lipomas very challenging. We review a case of intramyocardial lipoma in the distal interventricular septum that was initially detected on a low-dose computed tomography for lung cancer screening and the subsequent findings on cardiac MRI that made the diagnosis. Additionally, this case also helps to support the conservative management of intramyocardial lipomas that are more distal in the left ventricle and subsequently at lower risk for conduction arrhythmias.
RESUMO
Cardiac lipomas are extremely rare benign neoplasms of the heart. Most of them do not cause clinical symptoms, so far they are found incidentally in the majority of cases. Here, we describe a case of left intraventricular lipoma in an asymptomatic 34-year-old man which found by transthoracic echocardiography at comprehensive medical examination. Echocardiography and magnetic resonance imaging demonstrated a 3 × 3-cm mass in apical wall of the left ventricle, which was diagnosed as lipoma or liposarcoma. Although he was asymptomatic, tumor resection was indicated to confirm a diagnosis of the tumor and to prevent of future fatal complications. Surgery was performed with endoscopic assistance, and the tumor was resected. Histological examination of the tumor specimens consistent of lipoma. The patient is currently asymptomatic, and no recurrence was seen after 4 years.

Background: Primary cardiac tumors are often benign and commonly present as cardiac myxomas (CMs) or papillary fibroelastomas (CPFEs). There is a paucity of prognostic indicators for tumor burden or potential for embolic cerebrovascular events (CVEs). This study was performed to address these gaps. Methods: Medical records at the University of Florida Health Shands Hospital between 1996 and 2021 were screened to identify patients with CMs or CPFEs. Clinical features, echocardiographic reports, and CVE outcomes were quantitatively assessed. Results: A total of 55 patients were included in the study: 28 CM (50.9%) and 27 CPFE (49.1%) patients. Baseline patient characteristics were similar among patients. The neutrophil-lymphocyte ratio was correlated (p < 0.005 in all cases) to three metrics of tumor size in both CM (r = 64-67%) and CPFE (r = 56-59%). CVEs were the presenting symptom in 30 (54.5%) patients. CVE recurrence was high; the 5-year CVE recurrence rate in patients with tumor resection was 24.0% compared to 60.0% without resection. No baseline patient characteristics or tumor features were associated with an initial presentation of CVEs compared to any other indication. Univariate analysis indicated that prolonged duration to surgical resection, left atrial enlargement, male sex, and a neutrophil-lymphocyte ratio >3.0 at the follow-up were significantly associated with 5-year CVE recurrence. Left atrial enlargement and a neutrophil-lymphocyte ratio >3.0 at the follow-up remained significantly associated with 5-year CVE recurrence in multivariate analysis. Conclusion: The neutrophil-lymphocyte ratio may prognosticate tumor size and recurrence of neurologic events. An increased risk of CVE within 5 years of mass resection is almost exclusive to patients initially presenting with CVEs.
RESUMO
Cardiac hemangiomas are very rare benign cardiac tumors. They can present at any age and clinical presentation varies according to location and size. We encountered an 87-year-old woman with a left atrial hemangioma clinically diagnosed as cardiac myxoma. Histopathological examination revealed that it was a cavernous-type hemangioma Left atrial hemangiomas, especially those attached to the left atrium wall, may be mistakenly diagnosed as myxomas. Furthermore, a comprehensive review of atrial hemangioma was conducted for the diagnosis and treatment of this uncommon entity.
RESUMO
Representing 10%-25% of the primary cardiac neoplasms, primary malignant cardiac tumors (PMCT) have a poor prognosis, yet with rare incidence. Constituting more than 50% of the PMCT, cardiac sarcoma has increased not only in incidence over the past five decades but also in severity. Patients with PMCTs, especially sarcomas, have the worst prognosis when compared with other cardiac or extracardiac tumors. This retrospective study was performed using SEER*stat software, latest version 8.3.9.2(5) by accessing seer 18 registries plus data (excl AK) Nov 2020 Sub (2000-2018) for standard mortality ratio (SMR). A total of 235 patients were identified of whom 49.4% were females. Most of our patients were Stage 4 (n = 81) and distant in location (n = 92). The most common treatment method was tumor-directed surgery (n = 164), chemotherapy (n = 146), and radiotherapy (n = 55). Furthermore, other associated cancers with cardiac sarcoma were rare, with ten cases with lung and bronchus cancer (SMR: 37.95, 95% confidence interval [CI]: 18.2, 69.8), four with bone and joints (SMR: 1726.05, 95% CI: 470.2, 4419.3). During a 5-year follow-up, 235 patients died primarily due to cardiac sarcoma (n = 182, 77.4%), other cancers (n = 34, 14.4%), and other noncancerous causes (n = 19, 8%), while the noncancerous causes were attributed mainly to cardiovascular diseases (n = 4, 21%, SMR: 4.95, 95% CI: 1.35, 12.67), septicemia (n = 2, 10.5%, SMR: 41.23, 95% CI: 4.99, 148.95).

BACKGROUND: Burkitt lymphoma (BL) is a rare disease with the sporadic variant accounting for less than 1% of adult non-Hodgkin lymphomas. BL usually presents with an abdominal bulk, but extranodal disease affecting the bone marrow and central nervous system is common. Cardiac manifestations, however, are exceedingly rare, with less than 30 cases reported in the literature. CASE PRESENTATION: We report on a 54-year-old male patient with a six week-long history of paranasal sinus swelling, fatigue and dyspnea on exertion. Stage IV sporadic BL with extensive lymphonodal and cardiovascular involvement was diagnosed. Manifestations included supra- and infradiaphragmatic lymphadenopathy as well as infiltration of the aortic root, the pericardium, the right atrium and the right ventricle. EBV-reactivation was detected, which is uncommon in the sporadic subtype. After initial full-dose chemotherapy with very good BL control, the patient developed acute, but fully reversible cardiac insufficiency. Myocardial lymphoma involvement receded completely during the following two therapy cycles, while cardiac function periodically deteriorated shortly after chemotherapy administration and quickly recovered thereafter. Interestingly, the decline in cardiac function lessened with decreasing myocardial lymphoma manifestation. Once the cardiovascular BL infiltration was resolved, cardiac function remained stable throughout further treatment. Following seven cycles of chemotherapy and mediastinal radiation, the patient is now in continued complete remission. CONCLUSIONS: Although rare, cardiac involvement in BL can quickly become life-threatening due to rapid lymphoma doubling time and should therefore be considered at initial diagnosis. This case suggests an association between myocardial infiltration, chemotherapy associated tumor cell lysis and transient deterioration of cardiac function until the damage caused by the underlying lymphoma could be restored. While additional studies are needed to further elucidate the mechanisms of acute cardiac insufficiency due to lymphoma lysis in the infiltrated structures, prompt BL control and full recovery of the patient supports courageous treatment start despite extensive cardiovascular involvement.

RESUMO
Cardiac neoplasms are uncommon tumors. For epidemiological purposes, they can be divided into benign and malignant subtypes, with the former occurring at a significantly higher rate than the latter. Due to their uncommon nature, there are few data-driven studies examining the characteristics and trends of benign cardiac neoplasms. Our retrospective HCUP-NIS data review purports to illuminate some of the trends surrounding benign cardiac neoplasms and their associated co-occurrences. The data consisted of 482,872,274 weighted discharges. There were 45,568 weighted discharges that included a benign cardiac neoplasm. Benign cardiac neoplasms were more often observed in women (64.33%), and the average age was 63.8 years. The most common cardiovascular co-occurrences in patients with benign cardiac neoplasm were atrial tachyarrhythmias (28.93%), heart failure (19.61%), and embolic events such as stroke, myocardial infarct, or pulmonary embolism (19.82%). Other co-occurrences included pulmonary hypertension (7.55%), ventricular arrhythmias (3.23%), and other EKG abnormalities (3.70%). Procedures were numerous in patients with benign cardiac neoplasms. 43% of patients with this diagnosis had some form of cardiac surgery during their hospitalization. Overall, this study found low incidence of benign cardiac neoplasms in the USA during this 13-year study period. However, in the presence of benign cardiac neoplasms, our study showed that cardiovascular co-occurrences are not uncommon and may help to illuminate this otherwise rare diagnosis.

OBJECTIVE: This study aimed to examine the magnetic resonance imaging (MRI) characteristics of primary cardiac neoplastic lesions. METHODS: A retrospective investigation was conducted on 24 cases of primary cardiac neoplastic lesions as confirmed by surgery and pathology results. All the cases in this study received MRI multi-sequence and multi-dimension scanning, including the cardiac long-axis and short-axis cine sequences, parameter sequences of the cardiac long axis and short axis (T1WI, T2WI), first-pass perfusion sequence, and delayed enhancement sequence of the cardiac long axis and short axis. The age and gender of the patients and the location, size, signal characteristics, and relationship with the neighboring tissues of all the lesions were examined. RESULTS: Twenty-four cases of primary neoplastic lesions were examined in this study, the onset age was 11-72 years old, the median age was 53 years old, and the mean age was 46 years old. Among these cases, there were 8 cases including males and 16 cases including females, 19 cases were benign lesions; including 11 cases of myxoma, 4 cases of hemangioma, 1 case of paraganglioma, 1 case of PEcoma, 1 case of hamartoma, and 1 case of lipoma. The malignant lesions included 3 sarcomas and 2 lymphomas in 5 patients. CONCLUSION: MRI imaging provides a great value in the preoperative classification of primary cardiac neoplastic lesions.
RESUMO
Background Cardiac diffuse large B-cell lymphoma (cDLBCL) is an extremely rare disease. Introduction of rituximab has significantly improved survival in non-cardiac DLBCL, but there is limited data regarding the effects on outcomes in cDLBCL. We sought to evaluate the outcomes of cDLBCL in both pre- and rituximab eras. Methods We identified all cDLBCL cases in the Surveillance, Epidemiology and End Results (SEER) registry from 1975 to 2016. We compared survival (overall and lymphoma-specific) of patients diagnosed prior to versus after rituximab approval in 2006. Results A total of 106 patients were included in the final analysis. Median age was 69.5 years, 67% of the patients were white and 64% had local stage I/II disease. 67% of the patients were diagnosed after 2006 and thus belonged to the rituximab era group. Overall, 77% received chemotherapy, 24% had surgery and 15% had radiotherapy. Median overall survival (OS) for the entire cohort was 22 months. Median OS was 16 months (95% CI, 0.55-31) for the pre-rituximab group, versus 26 months (95% CI, 7.5-45) for the rituximab group (p = 0.34). Median lymphoma-specific survival (LSS) was 30 months (95% CI, 8.0-52) for the pre-rituximab group versus 36 months (95% CI, 16-158) for the rituximab group (p = 0.30). OS and LSS were also not significantly different between the two era groups when stratified by chemotherapy. In multivariable analysis, both OS and LSS were associated with lymphoma stage, insurance status and age but not with diagnosis era or chemotherapy. Conclusions Cardiac DLBCLs are rare and affecting mostly the elderly. Younger age, limited disease stage, and having health insurance but not lymphoma diagnosis era were associated with better outcomes.

Cardiac neoplasms are a diagnostic challenge on many levels. They are rare, their clinical presentation may mimic other much more common cardiac diseases, and they are at an uncommon intersection of oncologic and cardiac imaging. The pathology of primary cardiac neoplasms explains their varied imaging features, for example, calcification in primary cardiac osteosarcomas and T2 hyperintensity in myxomas. Integrating the imaging and pathologic features of cardiac tumors furthers our understanding of the spectrum of appearances of these neoplasms and improves the clinical imager's ability to confidently make a diagnosis.

Resumo Apresentamos o relato de caso de uma paciente com mixoma valvar mitral infectado e uma revisão da literatura sobre o assunto. Uma mulher de 33 anos apresentou histórico de febre e dispneia com evolução de alguns dias. Na hospitalização, ela apresentava uma síndrome semelhante ao lúpus, com hemoculturas positivas para Haemophilus spp . O ecocardiograma revelou uma massa gigante envolvendo ambos os folhetos mitrais associada à regurgitação grave, necessitando de troca valvar mitral biológica. A microscopia revelou mixoma infectado e a paciente recebeu alta assintomática após o término da antibioticoterapia. Ela apresentou bons resultados no seguimento. Este é o sexto caso de mixoma valvar mitral infectado relatado na literatura e o terceiro caso de mixoma cardíaco infectado pelo grupo HACEK. Devido à alta incidência de eventos embólicos, a antibioticoterapia precoce aliada à pronta intervenção cirúrgica são decisivos para a redução da morbimortalidade. O tempo para o diagnóstico foi muito mais breve do que o geralmente relatado em casos de endocardite por HACEK. A troca valvar foi a intervenção mais comum e todos os pacientes em relatos de caso anteriores apresentaram bons resultados no seguimento.
Abstract We present a case report of a patient with an infected mitral valve myxoma and a literature review on the subject. A 33-year-old female presented with a history of fever and dyspnea evolving over a few days. On admission, she had a lupus-like syndrome with positive blood cultures for Haemophilus species . Echocardiogram revealed a giant mass involving both mitral leaflets causing severe regurgitation, requiring biological mitral valve replacement. Microscopy showed an infected myxoma and the patient was discharged asymptomatic upon completion of antibiotics. She did well on follow-up. This is the sixth case of an infected mitral valve myxoma reported in the literature and the third case of a cardiac myxoma infected by the HACEK group. Exceedingly high incidence of embolic events makes prompt imaging, antibiotic therapy and surgery crucial for better outcomes. Time to diagnosis was much briefer than usually reported in other cases of HACEK endocarditis. Valve replacement was the most common surgical procedure and all patients from previous reports did well on follow-up.

We report the case of a 71-year-old man affected by testicular large B-cell lymphoma (DLBCL), treated with right orchiectomy and first-line chemotherapy (R-CHOP, 8 cycles). A complete remission was obtained after therapy. Twenty-two months after the primary diagnosis the patient suddenly presented dyspnoea and superior vena cava syndrome; thus, he underwent a CT scan that revealed a large mass in the right atrium, expanding to the superior vena cava. A differential diagnosis between a neoplastic mass and a clot was proposed. The subsequent MR did not clarify the nature of the mass; therefore, the patient underwent an 18F-FDG PET/CT scan (PET/CT), after a specific preparation to reduce fluoro-deoxyglucose (FDG) myocardial uptake. PET/CT revealed an intense FDG uptake involving the whole mass (SUVmax 9.4), suggestive for neoplasm and confirmed by the subsequent endocardiac biopsy. The patient was treated with 8 cycles of R-COMP, obtaining a complete remission, as indicated by the PET/CT performed after the seventh cycle of therapy. The case that we are reporting highlights that DLBCL can have an uncommon relapse presentation in the atrium. PET/CT, compared to conventional imaging, can be a valuable tool to detect early and better characterize cardiac lesions in order to improve the poor prognosis of these conditions.
RESUMO
BACKGROUND: Primary cardiac lymphoma (PCL) is a rare cardiac neoplasm. The most common type is diffuse large B-cell lymphoma, which mainly involves the right atrium and right ventricle. Its clinical manifestations are not specific. It is usually found late and the prognosis is poor. PCL is more common in immunodeficient patients. In view of the rarity of PCL, we have made a case report and a brief literature review. CASE PRESENTATIONS: We documented an elderly male patient with Burkitt's lymphoma diagnosed by echocardiography and percutaneous biopsy because of chest tightness. Chemotherapy was given to the patient, and the patient's condition was alleviated without recurrence. CONCLUSIONS: Primary cardiac lymphoma is a highly malignant tumor. Early detection, diagnosis and treatment are crucial to the prognosis of PCL. At present, the most effective treatment is chemotherapy. There are more chemotherapy schemes and treatment methods worth studying.
