An exceptionally giant left atrial myxoma: a case report and literature review.

BACKGROUND: Cardiac myxomas are considered the most common benign heart tumours. The clinical manifestations mainly depend on the size of the tumour. They usually vary from asymptomatic, mild non-specific symptoms, to severe obstructive cardiac and systemic findings. We describe herein a significantly large left atrial myxoma in a patient misdiagnosed with respiratory asthma. CASE SUMMARY: A 54-year-old lady, was diagnosed previously with asthma, presented with a history of dyspnoea on exertion, palpitations, and mild peripheral oedema. Chest X-ray suggested pulmonary congestion. Due to high suspicion of cardiac issues, transthoracic echocardiography was done revealing giant left atrial mass. Consequently, the mass was approached and excised surgically through the inverted T biatrial incision. Grossly, the mass measured 10 × 8 × 6 cm, and it had a smooth surface and was filled with gelatinous material. The histopathology confirmed benign myxoma without malignant features. DISCUSSION: Our article mainly focuses on the diagnostic challenges of a patient with atrial myxoma. The major discrepancy between the tumour size and the severity of the patient's symptoms should draw physicians' attention to consider atrial myxoma over a long list of differentials, in order to take immediate action to reduce the mortality and improve the overall prognosis.

Factor VII deficiency: do all need replacement for cardiac surgery?

In cardiac surgery, supplementation with recombinant factor VIIa is the treatment of choice for patients with factor VII deficiency, but overzealous administration can be associated with thromboembolic side-effects. A 53-year-old man with factor VII activity 15.2%, international normalized ratio 2.9, and acute thrombotic critical coronary anatomy, underwent coronary artery bypass surgery and a thoracotomy with decortication 5 months later. He was managed successfully without recombinant factor VIIa supplementation. This case demonstrates that current bedside and laboratory tests such as thromboelastography, prothrombin time or international normalized ratio, and factor VII activity may not predict replacement therapy in these patients.

Management issues during postinfarction ventricular septal defect and role of perioperative optimization: A case series.

The development of a myocardial infarction ventricular septal rupture is a rare fatal complication, and the surgical repair is the treatment of choice. In most of the scenarios, the operation will be done as an emergency procedure that carries high mortality. Prognosis of these patients depends on prompt echocardiographic diagnosis and the proactive medical and surgical therapy. More recently, various options have been put forward including the timing for surgery, percutaneous closure devices, and the improved outcome with initial stabilization with medical treatment including mechanical support. In this retrospective case series, we are presenting the management of these patients who presented us in different clinical scenarios and trying to identify the risks for the poor outcome and to formulate a strategy to improve the outcome.

An unsuspected diagnosis of mucoepidermoid carcinoma of lung.

A 40-year-old man with dry cough for 5 years, no history of smoking, and a right lung mass, underwent a radiologically-guided core needle biopsy. The initial histopathological diagnosis was adenocarcinoma of the lung. After lobectomy, the final pathology was mucoepidermoid carcinoma. The initial biopsies sampled only a mucinous component of the tumor, leading to a diagnosis of adenocarcinoma. The possibility of mucoepidermoid carcinoma could be suspected on the basis of clinical history and radiologic evidence. This unusual case highlights the importance of adequate multidisciplinary review of patients who increasingly receive pathologic diagnoses based on ever smaller tissue samples.
