Atrial myxomas are benign primary cardiac tumors. They can present with nonspecific symptoms, ranging from constitutional symptoms and embolic phenomena such as transient ischemic attacks (TIAs) or strokes to sudden cardiac death. Early diagnosis may be a challenge due to the nonspecific presentation of atrial myxoma. A high degree of suspicion is needed in patients with TIA having no known cardiovascular risk factors. Although benign, if left untreated, it can lead to serious complications ranging from embolic phenomena and obstructive symptoms to sudden cardiac death. An echocardiogram is of fundamental importance in diagnosing atrial myxoma, and surgical resection is the ultimate treatment of choice. Here, we discuss a case of TIA as the initial presentation of atrial myxoma.

Cardiac myxomas are rare tumors with risks of cardiac outflow obstruction and embolic events. Surgical excision of the tumor at the earliest is the definitive treatment. We report the successful anesthetic management of a 65-year-old female patient with incidental left atrial myxoma for right proximal femur nailing. The patient was asymptomatic with no significant cardiac history. Since fracture reduction cannot be deferred for a prolonged period, the case was taken up under general anesthesia with invasive blood pressure monitoring.

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. Our findings highlight the necessity of a comprehensive diagnostic approach, including the early use of resting transthoracic echocardiogram, to unveil less common causes like atrial myxoma. This case reinforces the pivotal role of considering alternative diagnoses in complex presentations of DOE, thereby guiding more accurate and tailored patient management.

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. Current multimodal diagnostic tools together with the multidisciplinary evaluation of the HeartTeam allowed an accurate diagnosis and an adequate management of the clinical picture.

UNASSIGNED: 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.
UNASSIGNED: Illustrative case presentation and literature review.
UNASSIGNED: I admitted a 28 y woman transferred to the comprehensive stroke center with an ischemic stroke treated with intravenous thrombolysis. She had a two year history of skin lesions in the hands/fingers and feet/toes/sole. Skin biopsies showed perivascular neutrophilic inflammatory dermatitis without skin vasculitis. Admission physical exam was notable for chronic skin changes on her hand and foot and an acute erythematous petechial rash over the right side of her face in the distribution of the right external carotid artery. MRI brain showed ischemia involving the right internal carotid artery territory. Transthoracic echocardiogram identified a 2.4 cm atrial myxoma with normal mitral valve function. She underwent uncomplicated cardiac surgery with confirmation of a villous myxoma. At her 8 week follow up visit, she had resolution of her neurologic deficits, and her skin rashes had cleared.Literature review identified 17 additional published cases of sentinel rashes preceding diagnosis of atrial myxoma. Skin changes were often reported in the hand and feet and may involve the digits, palm, and sole. In 8 cases, skin biopsy identified myxomatous emboli in dermal vessels. These cutaneous manifestations share similarities with Osler nodes and Janeway lesions first described in the 1890\'s, now understood to represent microemboli to the dermis. Seven of these 17 cases (41 %) developed strokes after the initial presentation of cutaneous changes. Our patient had an embolic event primarily affecting the right common carotid artery territory with facial cutaneous changes due to emboli to the external carotid artery territory and cerebral ischemia in the right internal carotid artery territory.
UNASSIGNED: I recommend reclassification of the cutaneous signs of atrial myxoma as embolic (to the dermis microvasculature) rather than a constitutional symptom. As the skin biopsy often fails to show myxomatous emboli, physicians should have a high suspicion for a proximal embolic source for patients with a migratory rash preferentially affecting distal extremities. Earlier diagnosis of atrial myxoma when the sentinel rash first appears provides a valuable window of opportunity for cardiac surgery before the patient experiences stroke or peripheral emboli.

Left atrial masses are commonly caused by atrial myxomas and metastatic tumors. Primary cardiac sarcomas are rare. Patients present with symptoms related to the tumor location. There are only a few case reports on this rare disease. We report the case of a 17 years old male patient presented with shortness of breath for 2-month duration. Echocardiography revealed a left atrial mass that was later surgically excised and histopathology confirmed a primary cardiac sarcoma. We discuss the diagnostic and therapeutic challenges encountered in the management of this rare disease. To the best of our knowledge, this is the first case reported in East Africa.

This is a case of acute coronavirus disease 2019 pneumonia that revealed an incidental large atrial myxoma with obstructive physiology that ultimately required emergent treatment with a definitive atriotomy and resection of the underlying myxoma.

Cardiac tumours are uncommon in the general population and even more so in the paediatric population. Here we present a case of an asymptomatic 7-year-old male with history of high-risk neuroblastoma who underwent 1-year post-treatment surveillance scan with an incidental finding of intracardiac lesion found to be an atrial myxoma.
