The differential diagnosis of myocardial infarction in patients with a number of potential causes can be challenging, especially when there is no angiographic evidence of coronary obstruction. We describe a case of extensive anterior ST-elevation myocardial infarction in a young male smoker who had a left atrial myxoma and a history of cocaine use 10 hours before the event. Clinical reasoning during a myocardial infarction investigation should be oriented by the probability of the causal relationship between the ischemic event and each factor present in the clinical context...

A 69-year-old female with left atrial tumor was refered to our hospital for surgical treatment. The tumor was attached to the interatrial septum and resected completely. Histopathological analysis confirmed a myxoma with ossification(mature bone). These findings may support the hypothesis that the undifferentiated mesenchymal cells are the origin of cardiac myxoma.

Cardiac myxomas are frequently located in the left or right atria, with multiple locations being rare. We report a 59-year-old healthy female with 5 months of cough and exertional dyspnea. A transthoracic echocardiography (TTE) exhibits a 9 × 5 cm nonpedunculated tumor arising from the interatrial septum (IAS) and inhabiting both atria, but was unable to depict the relation with the IAS. Transesophageal echocardiography exposes a single tumor crossing the IAS through an ostium secundum atrial septal defect (ASD) causing right heart functional impairment...

Interleukin (IL)-6 is a pleiotropic inflammatory cytokine with both pro- and anti-inflammatory capacities, produced by different cells and tissues, such as leukocytes, adipocytes, and endothelium. From the viewpoint of cardiologists, this cytokine is a reliable biomarker of cardiac dysfunction, occurrence of atrial fibrillation, cardiac myxoma with recurrence, remote metastasis or embolization, and atherosclerotic processes. Although IL-6 levels were detected in patients undergoing cardiac operations and reported sporadically, the perioperative kinetics of IL-6 in cardiac surgical patients was insufficiently elaborated...

There was no report on the application of totally endoscopic surgery for giant atrial myxoma resection. A 62-year-old female patient with giant atrial myxoma causing severe mitral stenosis and acute pulmonary edema underwent a successful operation by totally endoscopic techniques without the assistance of robotic systems using four small trocar ports (three 5-mm trocars and one 12-mm trocar). The patient recovered uneventfully and was satisfied with cosmetic results.

BACKGROUND: Carney complex (CNC) is a very rare disease. Although thyroid lesions are included in the diagnostic criteria for CNC, they are an infrequent occurrence. CASE PRESENTATION: The patient was a 69-year-old woman who had undergone the removal of a left atrial myxoma 10 years earlier, at the age of 59. At the time of the operation, thyroid ultrasonography (US) revealed multiple hypoechoic nodules. Thyroid scintigraphy revealed an increased uptake of 99m Tc in these lesions, which was consistent with toxic multinodular goiter, and she was diagnosed with CNC...

Cardiac myxomas are the most common type of primary cardiac tumour. The most common location of cardiac myxoma is left atrium. Right atrial myxomas are very rare and usually asymptomatic or sometimes present with dyspnoea. Right atrial myxoma presenting as a right-sided heart failure is very rare. We report a very rare case of a 52-year-old man of right atrial myxoma presented unsually as right-sided heart failure.

Cardiac myxoma is a benign tumor, but it is known for its space-occupying effect at the site of origin and frequent systemic embolization. This case report highlights a biatrial myxoma of interatrial septum who presented with significant tricuspid valve regurgitation, atrial fibrillation, and cardioembolic stroke of the left parietal lobe, i.e., a biatrial myxoma with triple ripples.

Emboli are common clinicopathologic findings. Recognition of the type of arterial emboli could be the first clue to the original source. Emboli with myxomatous changes are rare. Myxoma-like features in mural organizing thrombi have been reported. The most challenging differential diagnosis is between embolic cardiac myxomas and myxomatous thromboemboli. Emboli from sarcomas and arteriosclerotic plaques with myxoid features are also potential pitfalls. There is scarcity of studies focusing on myxoid emboli and their clinical and pathologic importance...

Objective: This paper reports a 20 years' experience in the management of atrial myxomas at our institution. Apart from presenting our experience of their clinical presentation, surgical management, post-operative complication, and long-term follow-up we investigated any correlation between left and right sided tumor with their symptom of presentation. Materials and Methods: The data were retrospectively collected for patients between the period 1995 and 2015 from the hospital database...

RATIONALE: Carney complex (CNC) accounts for up to two-thirds of familial cardiac myxoma, which is a rare autosomal dominant syndrome characterized by multiple mucocutaneous lesions and endocrine tumors. Mutation in the cAMP-dependent protein kinase A (PKA) regulatory (R) subunit 1 (PRKAR1A) gene has been identified as a cause of CNC. In this article, we report 3 first-degree relatives with cardiac myxoma who were diagnosed with CNC and underwent surgical resection. PRESENTING CONCERNS: The recurrence of cardiac myxoma was detected in a 45-year-old male by echocardiography 5 years after the resection was carried out, without any additional symptoms...

The strategy for the successful removal of gigantic myxoma of the left atrium obstructing inflow into the left ventricle is presented. We consider an anterolateral minithoracotomy approach superior to median sternotomy for complete and comfortable atrial tumour excision because of the excellent exposure and the cosmetic outcome. After removal, local cryodestruction of potential remnant cells is mandatory to prevent recurrency.

A 47-year-old female, with multiple comorbidities, presented with a cough of two months, loss of weight and appetite. She was treated for pneumonia. A chest X-ray showed bilateral reticulonodular opacities. She was noted to have a vague central abdominal mass and a systolic murmur over the mitral region. Ultrasonography and computed tomography of the abdomen showed an omental mass and loculated ascites. Oesophagoduedenoscopy showed antral gastritis and during colonoscopy the surgical team was unable to advance the scope beyond 40 cm due to external compression...

A 23-year-old Asian student presented to our service with a 1-month history of fever, weight loss of 10 kg, night sweats, fatigue and general malaise. He was previously well with no significant medical or family history. He had a low-grade pyrexia and cardiac auscultation revealed a diastolic murmur consistent with 'tumour plop'. He had no sequelae of endocarditis. He had low-grade pyrexia of 37.7°C, and ECG showed sinus tachycardia at 130 bpm. He had raised inflammatory markers and was started on broad spectrum antibiotics...

Atypical presentation of myxomas in the two cases described here arise from the fact that both patients were asymptomatic and both showed unexpected echocardiographic findings. Asymptomatic presentation is very rare, and occurs in only about 10% of individuals. Atrial myxomas discovered on incidental echocardiography is also a rare phenomenon, as seen in our cases. Early diagnosis and timely surgical treatment allow these patients to live a completely asymptomatic life.
