“…Cardiac CT can assist in evaluating the coronary arteries and other cardiac structures before surgery [ 5 ]. Cardiac MRI or cardiac CT can be combined with fluorodeoxyglucose positron emission tomography (FDG-PET), which demonstrates tumor metabolic activity helping differentiate between benign and malignant tumors [ 10 ]. Cardiac myxomas will demonstrate no or low metabolic activity while malignant tumors demonstrate high metabolic activity [ 10 ].…”

Large Right Atrial Myxoma: A Rare Presentation

We present a case of a 74-year-old female with a large right atrial myxoma who initially presented to her primary care physician with nonspecific constitutional and abdominal symptoms. Her presenting symptoms were initially thought to originate from her gastrointestinal tract, but her workup for a gastrointestinal disorder was nondiagnostic. It was not until this patient developed symptoms of overt right heart failure that a cardiac condition was suspected. Our case highlights the importance of understanding the potential of cardiac myxomas to mimic many diseases, including cardiac, infective, neurologic, immunologic, pulmonary, and malignant diseases. Therefore, clinicians must always maintain a high index of suspicion for cardiac myxomas when evaluating patients with cardiac and non-cardiac-related symptoms that may be due to these tumors.

“…Nevertheless, among all the chambers of the heart, the presence of a mass in the right atrium poses distinct difficulties due to typical structural variations that can imitate a tumor.

“…the likelihood of thrombi or vegetations, which can also mimic a tumor. 1 The primary cause of a mass in the right atrium is typically a thrombus resulting from the connection between the right atrium and the deep venous system. 2 However, the presence of a mass in the right atrium should raise concerns about the possibility of a neoplasm, which can be either benign or malignant.…”

Metastatic right atrial mass in the presence of atrial septal defect: A rare clinical coincidence

Key Clinical MessageThe key takeaway from this clinical scenario is to choose the most appropriate and reasonable treatment plan when dealing with a patient who has atrial septal defect (ASD) and concurrent atrial and mediastinal masses. In such cases, a heart‐oncology team should make the therapeutic decision.AbstractRight atrial masses are not pretty rare and might be a diagnostic challenge. Thrombosis, tumors, and vegetations are primary differential diagnoses. Workup for these masses usually includes multimodality imaging and biopsy in selected cases. We report a case of a 37‐year‐old lady who presented with cough, dyspnea, and head and neck swelling after a cesarean section. Echocardiography revealed a right atrial mass accompanied by a secundum type atrial septal defect (ASD). Pulmonary CT Angiography was performed, in which a lobulated mass in the anterior mediastinum was detected, and a heart‐oncology team made the therapeutic decision. The patient was scheduled for surgical ASD closure and concomitant tissue biopsy. The pathology results were in favor of poorly differentiated germ cell tumors, and chemotherapy was started following the surgery. After two sessions of chemotherapy, the tumor did not respond to the primary regimen. Thus, an updated regimen was initiated. Compliance with the updated regimen was acceptable, and the patient is currently under treatment and follow‐up.

Adherent Right Atrial Cardiac Lipoma with Obstructive Symptoms: An Unusual Case Report

Benign cardiac tumors are rare, and cardiac lipomas constitute a small proportion. Since the majority of these lipomas vary in morphology, size, clinical presentation, and diagnosis, it is difficult to diagnose them until they become symptomatic. Management of large adherent cardiac lipomas presenting with obstructive symptoms can be challenging. It can be arduous to excise them completely, as they may involve vital structures and may sometimes need debulking only, leading to the possibility of recurring tumors. We report a case of a 60-year-old male with complaints of chest pain and dyspnea on exertion, diagnosed with a large right atrial mass, extensive involvement of the right atrial wall, and impingement on the tricuspid valve and was managed by surgical resection with a positive clinical result. This case highlights that obstructive or symptomatic cardiac lipomas can be effectively resected with favorable outcomes.
