Overview
Myxoma of the heart, also known as cardiac myxoma, is a rare, typically benign primary cardiac tumor that arises from the endocardium, often attached to the atrial septum, particularly the left atrium. It can cause significant hemodynamic disturbances and embolic events 12.Diagnosis
Clinical Presentation: Symptoms may include dyspnea, palpitations, syncope, and embolic phenomena (stroke, systemic emboli).
Physical Examination: Atrial murmur, especially heard best at the apex, and signs of heart failure.
Imaging: Echocardiography is crucial for diagnosis, showing characteristic mobility and appearance of the tumor.
Electrocardiography (ECG): May reveal atrial fibrillation or other arrhythmias secondary to the tumor.
Cardiac MRI/CT: Provides detailed anatomical information and helps assess tumor extension and involvement 1.Management
Surgical Excision: First-line treatment, typically via open-heart surgery or minimally invasive techniques, aiming for complete resection to prevent recurrence 1.
Anticoagulation: Preoperative and postoperative anticoagulation to reduce embolic risk, specific drug classes and doses vary based on clinical scenario 1.
Postoperative Monitoring: Close follow-up with echocardiography to monitor for recurrence or complications 1.Special Populations
Pediatrics: Limited data; management principles similar to adults but with considerations for growth and development 1.
Elderly: Increased risk of comorbidities; surgical risk stratification is crucial before proceeding with excision 1.Key Recommendations
Surgical excision is the definitive treatment for cardiac myxoma to prevent recurrence and embolic events (Evidence: Strong 1).
Echocardiography is essential for diagnosis and preoperative assessment of cardiac myxoma (Evidence: Strong 1).
Postoperative anticoagulation should be considered to mitigate embolic risk, tailored to individual patient factors (Evidence: Moderate 1).References
