Atrial myxoma

A 51-year-old male with a complicated medical history presented with shortness of breath. Preoperative workup confirmed the presence of a large atrial mass. However, delayed gadolinium enhancement CMR with long inversion time (TI 600) showed lack of enhancement, which was suggestive of a thrombus. During cardiac magnetic resonance imaging, delayed gadolinium enhancement sequences with long inversion time (TI 600) are commonly used to distinguish between an avascular thrombus versus a vascular tumor.

Atrial myxoma, though the most common primary cardiac tumor, often presents with nonspecific symptoms that can obscure its diagnosis. This case report details an unusual presentation of dyspnea on exertion (DOE) in a patient initially considered to have chronic obstructive pulmonary disease (COPD), a common pulmonary etiology of DOE. The diagnostic journey underscores the critical importance of considering atrial myxoma in patients with DOE, especially when symptoms are not fully explained by apparent pulmonary conditions...

BACKGROUND: Left atrial myxoma during pregnancy is rare. We present three cases in order to aid in the management. CASE PRESENTATION: Three cases of left atrial myxoma during pregnancy were presented in this article. Three patients all received multidisciplinary team work and acquired good outcomes. The case 1 had no symptoms and delivered before traditional cardiac surgery. The case 2 and case 3 undergone totally endoscopic minimally invasive cardiac surgery during pregnancy...

BACKGROUND: Cardiac myxomas (CM) are the most prevalent type of primary cardiac tumour. The majority of primary cardiac tumours, including CM, are found to be benign. In the context of this study, the objective was to investigate and analyse the experience of CM over a period of 10 years, specifically in Bahrain. By examining this particular subset of cardiac tumours, valuable insights can be gained regarding their prevalence, clinical presentation, diagnostic methods, treatment approaches, and outcomes in the Bahraini population...

Here, we present a case of choriocarcinoma with metastasis only to the right inferior pulmonary vein and heart, which is unusual, as the skipping of lung metastasis is extremely rare. The 34-year-old patient presented with cough and hemoptysis. The diagnosis was challenging due to the absence of gynecological abnormalities and elevated β-HCG levels, only revealing a cardiac mass upon imaging. While no abnormalities were found through gynecological ultrasound or gynecological examination, the serum human chorionic gonadotropin β subunit (β-HCG) level was abnormally raised...

INTRODUCTION AND IMPORTANCE: Systemic lupus erythematosus (SLE) predominantly affects young women and is associated with an increased risk of thrombosis. Antiphospholipid antibody syndrome (APS) may complicate the clinical picture, often leading to recurrent arteriovenous thrombosis. This case report underscores the significance of two unique aspects: the rare occurrence of an atrial thrombus and the presence of antinuclear antibody (ANA)-negative SLE. CASE PRESENTATION: A 32-year-old woman presented with a history of symmetric polyarticular joint pain, oral ulcers, significant weight loss, and a history of unprovoked popliteal thrombosis and two unexplained abortions...

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...

BACKGROUND: Myxomas are the most common primary cardiac tumor and typically originate in the left atrium. Atrial myxomas may present following complications of obstruction and emboli. If an atrial myxoma goes untreated, complications such as congestive heart failure, embolic stroke, and sudden death can occur. CASE PRESENTATION: A 58-year-old Caucasian male presented following a cardiac arrest. He was taken emergently to the cardiac catheterization lab and received two drug eluting stents...

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...

Cardiac myxoma is the most common primary heart tumor in adults. Although biologically benign, they can be life-threatening by obstructing heart function. They typically develop in the left atrium and can be polypoid (causing more obstruction) or papillary (more likely to cause embolizations). Symptoms are nonspecific, and diagnosis is relatively rare. Echocardiography is essential for quick diagnosis, and surgical removal is the primary treatment with low mortality rates, excellent postoperative survival, and low recurrence rates...

BACKGROUND: Minimally invasive surgery has emerged as a favorable alternative to conventional surgery for various cardiac conditions. This study aimed to compare the perioperative outcomes and follow-up results of the robotic approach versus the sternotomy approach for left atrial myxoma (LAM) resection. METHOD: We retrospectively analyzed the perioperative outcomes and follow-up results of 94 patients who underwent left atrial myxoma resection using either the sternotomy approach (n = 64) or the robotic approach (n = 30) at our center between January 2017 and April 2023...

Cor triatriatum sinister is a rare entity characterized by a membrane within the left atrium and posterior to the atrial appendage. This defect may cause obstructive symptoms analogous to mitral stenosis. The authors present a case of an incidentally detected enhancing mass originating from a cor triatriatum sinister membrane, with imaging characteristics most suggestive of myxoma. Keywords: MR Imaging, Cardiac, Left Atrium, Congenital, CT Angiography, Echocardiography Supplemental material is available for this article ...

BACKGROUND: Primary cardiac tumors are uncommon, with the majority being benign myxomas. Cystic myxoma, a particularly rare type of benign cardiac tumor, demands cautious differential diagnosis from other cardiac tumors. CASE SUMMARY: A 43-year-old male patient presenting with intermittent dyspnea was referred to our department for surgical evaluation. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) unveiled an intra-left atrial cyst, which was subsequently found to be blood-filled during a video-assisted microinvasive heart surgery...

A previously healthy woman in late adolescence presented to the emergency department with stroke-like symptoms following a two-month history of bilateral foot pain and oedema, accompanied by a macular rash and progressive lower extremity weakness. On further investigation, she was found to have multiple cerebral emboli and a left atrial myxoma fixed to the interatrial septum. The patient subsequently underwent urgent surgical excision of the myxoma. On follow-up, her cutaneous and neurological symptoms were significantly improved...

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...

INTRODUCTION: Presenting symptoms of atrial myxoma are classically viewed as a triad of cardiac, embolic, and constitutional symptoms. Dermatologic manifestations are viewed as constitutional symptoms and have not received much attention. METHODS: Illustrative case presentation and literature review. RESULTS: I admitted a 28 y woman transferred to the comprehensive stroke center with an ischemic stroke treated with intravenous thrombolysis...
