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.

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.

We report a rare case of a large left atrial myxoma that manifested as syncope in a patient who presented to the hospital following a syncopal episode. Our patient had a history of hypertension and anemia with reported two months of dyspnea on exertion. He was found to have a large left atrial myxoma. Atrial myxomas are the most common benign primary cardiac tumors. Patients may be asymptomatic or experience shortness of breath, palpitations, syncope, or sudden death. Cases of syncope caused by left atrial myxoma have been rarely documented. Our case report adds to the growing literature documenting this phenomenon. Larger observational studies are needed to properly define the incidence of left atrial myxoma causing syncope.

Myxomas are tumors that occur due to uncontrolled proliferation of mesenchymal cells. Cardiac myxomas although very rare, are still the most common primary tumor of heart. Cardiac myxomas have a prevalence of 0.03% in the general population. They can have a variety of clinical presentations with obstructive cardiac symptoms, constitutional symptoms and symptoms due to embolism to other body parts chief among them. CNS embolism with stroke is among the rarest clinical presentation of cardiac myxomas. Our article portrays a case of cardiac myxomas that initially resulted in episodes of dyspnea and syncope and eventually led to recurrent episodes of transient ischemic attack and stroke. Case was confirmed by transesophageal echocardiography and managed surgically by medial sternotomy. Myxoma, a benign primary cardiac tumor is itself a rare occurrence, embolization of myxoma leading to multiple strokes is an atypical clinical presentation. Our report would be a valuable addition to the already existing literature.

Syncope is a frequent reason for elderly patients to present to an outpatient office. The underlying cause of syncope can range from benign to serious. Although serious cases of syncope are rare, appropriate workup can help detect and address potentially fatal pathologies. We present a case of a 74-year-old woman who presented with an episode of syncope with associated epigastric cramping. Sudden syncope without significant comorbidities prompted further diagnostic workup, which revealed a rare cardiac myxoma. This case underscores the importance of ruling out potentially fatal causes prior to favoring more conservative diagnoses when investigating syncope in the elderly population.

The most common primary cardiac tumors in adults are atrial myxomas, with adolescent-onset being uncommon. In this case report, a 15-year-old female was hospitalized with cerebrovascular embolism and later diagnosed with a left atrial myxoma. She had previously shown signs of distal vascular micro thrombosis, including recurring bilateral lower extremity rash, which are crucial for the early diagnosis and differential diagnosis of atrial mucinous neoplasm. We reviewed the various clinical symptoms and diagnostic approaches to identify left atrial mucinous neoplasm. This patient also had a combination of endocrine-related diseases. We reviewed the diagnostic approach for the Carney Complex (CNC) and discussed the role of thyroid disease in diagnosing CNC.

The vague presentation of an atrial myxoma makes accurate diagnosis difficult. This case report reviews the case of a 54-year-old female who presented to the Emergency Department complaining of shortness of breath and back pain. Prior to her Emergency Department evaluation, she had been given a diagnosis with pneumonia. Upon further evaluation, she was diagnosed with a large left atrial myxoma that was surgically removed via median sternotomy. After recovering from her surgery, the patient had a full resolution of her symptoms. Although the treatment for myxomas has a high success rate of full recovery, the difficulty in diagnosis poses problems for patients and can prolong symptoms due to potential misdiagnosis.
