Thirty-five patients (10 men and 25 women) with a preoperative diagnosis of cardiac myxoma have undergone cardiac surgery since 1964 at the University of Louvain. The mean age of the patients was 49 (range 20-75) years. The most commonly encountered symptoms were: dyspnoea 49%; thoracic pain 26%; cough and peripheral embolism 17% each; stroke and preoperative atrial fibrillation 14% each; flutter 11%; expectoration, acute pulmonary oedema, syncope and transient ischaemic attack 6% each; and pulmonary embolism 3%. The different locations were: left atrium 66%; right atrium 26%; both atria 3%; right ventricle 3%: and retrohepatic vena cavae 3%. Septal implantation was found in 66%. Histological examination confirmed 28 myxomas but three 'tumours' were thrombi, two haemangiomas, one rhabdomyosarcoma and one liposarcoma. The follow-up has now reached 2829 months with an average of 81 months per patient (range 0-342 months). Three patients died early (9%) and there were four late deaths (11%). No cases were familial. Surgical resection is the correct treatment for cardiac myxomas and gives good long-term results.

Rationale: Thrombus is the most common occupying lesion in the cardiac chambers, it is often distinguished from cardiac neoplastic occupations. Among them, the most common is cardiac myxoma, whose imaging manifestations are often confused with thrombus. However, the 2 types of lesions have different therapeutic strategies and are both potentially high-risk sources of embolism, so early differentiation between intracardiac thrombus and cardiac tumor is essential.

Accuracy of transthoracic echocardiography in diagnosis of cardiac myxoma: single center experience.

Background: The differential diagnosis of cardiac myxomas (CM), the most common benign primary cardiac tumors, is broad and a thorough diagnostic workup is required to establish accurate diagnosis prior to surgical resection. Transthoracic echocardiography (TTE) is usually the first imaging modality used for diagnosis of suspected CM. In a single tertiary centre study, we sought to determine the accuracy, sensitivity, and specificity of TTE in the diagnosis of CM and to determine echocardiographic characteristics indicative of CM.

Left atrial myxoma is the most prevalent primary cardiac tumor, known for its high risk of systemic embolization. Although surgical excision remains the standard treatment, options are limited for high-risk patients. This case report introduces a novel approach using transcatheter electrosurgery to address a left atrial myxoma via a transseptal approach in a patient ineligible for conventional surgery due to the heightened risk of intracranial hemorrhage associated with cerebral amyloid angiopathy.

Papillary fibroelastomas (PFEs) followed by cardiac myxomas (CM) are the 2 most common primary benign cardiac tumors. Although typically asymptomatic, they can manifest with nonspecific symptoms such as dyspnea and dizziness or more acute manifestations such as embolic events. We describe an unusual location of a PFE typically seen with a CM.
