RESUMEN

BACKGROUND: Cardiac metastasis including the right ventricle from renal cell carcinoma is rare. No standard treatment for cardiac metastasis and recurrence in renal cell carcinoma has been established. CASE PRESENTATION: We present the case of a 61-year-old man who underwent the resection of recurrent right ventricular metastasis caused by renal cell carcinoma following molecular targeted therapy. The first cardiac operation was performed for right ventricular metastasis due to renal cell carcinoma. The patient had a good postoperative course. Two years after the first operation, however, follow-up computed tomography revealed the recurrence of the right ventricular tumor and metastases in both lungs. Molecular targeted therapy was carried out and effectively controlled the lung metastasis but the right ventricular lesion remained unchanged, leading to reoperation. The recurrent right ventricular tumor was completely resected through a redo median sternotomy assisted by cardiopulmonary bypass. The patient had an uneventful postoperative course and was discharged on the 13th postoperative day. Follow-ups at 2 years showed no cardiac recurrence. CONCLUSION: Surgical intervention was considered useful in managing the recurrence of right ventricular metastasis from renal cell carcinoma after molecular targeted therapy.

RESUMEN

A patient with ventricular tachycardia (VT) and right ventricular (RV) metastatic diffuse large B-cell lymphoma had persistent RV gadolinium enhancement following chemotherapy and disease remission. Electrophysiology study demonstrated inducible sustained monomorphic VT requiring subcutaneous implantable cardioverter-defibrillator implantation. This highlights the arrhythmogenic potential of residual scar after resolution of cardiac masses.

RESUMEN

A young patient, recently treated for squamous cell penile carcinoma, presented with acute myocardial infarction and severe heart failure. Despite repeatedly ruling out metastatic disease on imaging, surgery for a mechanical assist device revealed unexpected squamous cell metastasis in the pericardium. Consequently, palliative care was initiated.

RESUMEN

Radioligand Therapy (RLT) in the form of [177Lu] Lu-DOTA-TATE (Lutathera®) is a promising treatment for pancreatic neuroendocrine tumors (pNETs) with cardiac metastasis. We present a patient treated with [177Lu] Lu-DOTA-TATE that showed shrinkage of metastasis after four treatments at 7.4 GBq every 8 weeks.

RESUMEN

Adrenocortical carcinoma is a malignant tumor with a poor prognosis and a frequent metastatic extension. In very rare cases, a cardiac metastatic disease may occur, and surgical resection is essential for its management. MR-guided stereotactic radiotherapy is an attractive radiotherapy modality for the treatment of mobile thoracic tumors, enabling the target to be monitored continuously during irradiation, while the dosimetric plan can be adapted daily if necessary. We report here the case of a patient with intracardiac metastasis secondary to malignant adrenocortical carcinoma, treated with magnetic resonance imaging-guided stereotactic radiotherapy.

RESUMEN

Resumen El sarcoma sinovial primario del pericardio es un tumor muy raro y de mal pronóstico y se sabe poco en cuanto al manejo terapéutico. Presentamos el caso de una paciente de 51 años a quien se le realizó resección quirúrgica incompleta, quimioterapia y radioterapia. Hasta donde sabemos, este es el primer caso de un sarcoma sinovial primario de pericardio que luego de operado se mantuvo asintomático durante 5 años hasta que en una TAC de control se le detectaron metástasis cardiacas que comprometían las cavidades derechas y con quimioterapia, la ecocardiografía demostró la reso lución completa de las mismas.

Abstract Primary pericardial synovial sarcoma is an extraor dinarily very rare tumor with a poor prognosis, and little is known about its therapeutic management. We describe the case of a 51-year-old woman patient who underwent incomplete surgical resection, chemotherapy, and radiotherapy. To the best of our knowledge, no pri mary pericardial synovial sarcoma has been described which, after surgery, remains asymptomatic for 5 years, and until a control CT scan detects cardiac metastases that compromised the lumen of the right cavities and with chemotherapy, echocardiography demonstrated complete resolution of cardiac metastases.

RESUMEN

Melanoma is considered a masquerader of many diseases owing to its potential to metastasize to many organs. Several malignancies can metastasize to the heart including malignant melanoma. Historically, antemortem diagnosis of cardiac involvement of melanoma is not common, but with significant improvement in imaging modalities, the diagnosis can now be made early and accurately, aiding in treatment and improved survival. We present a case of a 36-year-old man with brief neurological symptoms and subsequent diagnosis of cerebrovascular accident (CVA). Cardiac imaging revealed incidental findings of right and left ventricular masses and lymph node biopsy, confirming metastatic melanoma. Cardioembolic etiology was suspected for his CVA. Prompt immunotherapy was initiated with improvement in his clinical condition.

RESUMEN

Neuroendocrine neoplasms represent an uncommon disease with an increasing incidence. Thanks to improvements in diagnostic and therapeutic methods, metastases previously considered uncommon, such as bone metastases, or even very rare, such as brain, orbital and cardiac metastases, are more frequently found in daily practice. Due to the great heterogeneity of these neoplasms, there is a lack of high-quality evidence on the management of patients with these types of metastases. The aim of this review is to provide the current state of the art, reviewing neuroendocrine neoplasm specific studies and useful information from other tumor types and to propose a treatment recommendation with algorithms to consider in daily clinical practice.

RESUMEN

Intrahepatic cholangiocarcinoma is a rare type of cancer that is usually discovered at an advanced stage where surgical treatment is not an option. When compared to standard systemic therapy, transarterial chemoembolization (TACE) can provide a survival benefit to unresectable patients. Extrahepatic tumor spread is not rare, but cardiac involvement is an unusual complication.We present the case of a 56-year-old man with histologically proven intrahepatic cholangiocarcinoma. Oncologic risk factors include hepatitis B and liver cirrhosis. Being in an unresectable stage of the disease, three TACE procedures were performed. Partial response was achieved (according to RECIST) leading to a 16-month survival. However, disease progression was present, with unusual heart metastases.TACE can bring a survival benefit to unresectable cholangiocarcinoma patients. Defining the best disease stages in which TACE can be implemented and introducing it as part of standard treatment guidelines still presents a challenge.

RESUMEN

Cardiac masses are currently studied using multimodality imaging. For diagnosis, different imaging techniques that can provide complementary information are used. Cardiac magnetic resonance imaging (MRI) has become a fundamental tool for this type of pathology owing to its ability to provide tissue characterization, spatial accuracy, and the anatomic relationships of the different structures. This study presents a series of four clinical cases with an initial diagnosis of a cardiac mass. All cases were evaluated at a single center, and patients were aged 57 to 72 years. An etiological study was conducted on all patients using different imaging techniques, including MRI. This study describes the diagnostic and therapeutic procedures of the four cases, which included two intracardiac metastases and two benign tumors. Cardiac MRI was decisive in the diagnostic process, determining the clinical decision-making in all four cases. Cardiac MRI has emerged as a pivotal technique in the diagnosis of cardiac masses. It can provide a highly accurate histological diagnosis without the need for invasive techniques.

RESUMEN

The heart is a rare site of cancer metastases, even from the most common malignancies, such as lung cancer. Cardiac metastases may lead to myocardial dysfunction. This report presents a case of lung cancer metastases to the left ventricular myocardium that clinically manifested as atypical symptoms of cardiac dysfunction. The metastases were not revealed until after the patient died. Posthumously, the anamnesis, autopsy results, and morphological examination were evaluated. We demonstrated that the atypical symptoms of cardiac dysfunction were caused by occult (undiagnosed) metastases of lung cancer cells to the heart. The doctors did not consider this variant as possible metastatic lung cancer, because the patient had been treated radically one year earlier.

RESUMEN

A 50-year-old woman who had previously undergone right radical mastectomy presented with chest tightness and shortness of breath after physical activities. A cardiac mass and multiple hepatic lesions were successively detected. We first performed hepatic puncture biopsy. Histopathologic examination confirmed that the multiple hepatic lesions were venous malformations. Based on the imaging findings and previous reports in the literature, we boldly speculated that the cardiac mass was also a venous malformation. The cardiac venous malformation was successfully resected, and the postoperative pathology confirmed our suspicion.

RESUMEN

Hepatocellular carcinoma (HCC) is primary hepatic malignancy with a high incidence of recurrence. The risk of recurrence directly correlates to patient's overall prognosis. Management of advanced HCC involves a combination of surgical resection, locoregional therapy, and systemic treatment. Distant metastases are rare, and intraventricular cardiac metastases are even more infrequent. This brief review details an illustrative case of cardiac metastasis after curative treatment of primary HCC and then summarizes the literature on risk factors, treatment options, and patient prognosis in the setting of distant metastases from HCC. Prognosis of metastasis to the heart is generally poor, and available evidence emphasizes the importance of maintaining regular posttreatment screening for metastases in patients with HCC. Given the variable presentation and high risk of recurrence, it is critical to have individualized multimodality treatment plans.

RESUMEN

Hepatocellular carcinoma is common in patients with cirrhosis regardless of the etiology. Its presentation is uncommon in patients without known cirrhosis. It can spread commonly to the lungs, abdominal lymph nodes and bone but cardiac metastases are rare. The screening and early diagnosis impact the treatment feasibility and prognosis. The most common etiologies of cirrhosis and hepatocellular carcinoma are alcohol consumption and viral hepatitis B and C, however, non-alcoholic fatty liver disease (NAFLD) is becoming a more pronounced known risk factor for steatosis, advanced liver fibrosis, cirrhosis, and thus hepatocellular carcinoma due to the rise of metabolic syndrome prevalence. Although a known risk factor, there are no current recommendations for cancer surveillance in patients with NAFLD. The aim of this paper is to raise awareness of this rising complication by describing a rare initial presentation of hepatocellular carcinoma.

RESUMEN

A 30-year-old man with a history of an in-situ melanoma of the forehead was referred for cardiac evaluation because of tachycardia and elevated levels of serum troponin. The transthoracic echocardiogram revealed multiple masses attached to the walls of both ventricles and the right atrium (RA). A large mass was occupying almost one third of the right ventricle (RV), resulting in reduction of the end-diastolic RV volume and tachycardia. A cardiac magnetic resonance imaging confirmed multifocal myocardial infiltration and intracavitary masses and excluded the presence of thrombus in any of the cardiac chambers. Diffuse metastatic involvement in the liver, the spleen, and the brain by computed tomography precluded surgical management. Being BRAF-unmutated, the patient was initially treated with a combination of nivolumab and ipilimumab. One month later, the cardiac metastases in RA and left ventricle were unchanged on echocardiogram, while the tumor in RV was enlarged occupying the majority of the chamber, resulting in further reduction of the cardiac output and tachycardia. The treatment was changed to a combination of dacarbazine and carboplatin, but the patient eventually died two months later. Heart is not a common metastatic site of melanoma and cardiac involvement is usually clinically silent making ante mortem diagnosis difficult. Multimodalidy imaging plays a pivotal role in the diagnostic work up. Cardiac melanoma metastases indicate an advance stage disease with poor prognosis.
