Symptoms may occur at any time, but most often they accompany a change of body position. Pedunculated myxomata can have a "wrecking ball effect", as they lead to stasis and may eventually embolize themselves. Symptoms may include: * Shortness of breath with activity * Platypnea – Difficulty breathing in the upright position with relief in the supine position * Paroxysmal nocturnal dyspnea – Breathing difficulty when asleep * Dizziness * Fainting * Palpitations – Sensation of feeling your heart beat * Chest pain or tightness * Sudden Death (In which case the disease is an autopsy finding) The symptoms and signs of left atrial myxomata often mimic mitral stenosis. General symptoms may also be present, such as: * Cough * Pulmonary edema – as blood backs up into the pulmonary artery, after increased pressures in the left atrium and atrial dilation * Hemoptysis * Fever * Cachexia – Involuntary weight loss * General discomfort (malaise) * Joint pain * Blue discoloration of the skin, especially the fingers change color upon pressure, cold, or stress (Raynaud's phenomenon) * Clubbing – Curvature of nails accompanied with soft tissue enlargement of the fingers * Swelling – any part of the body * Presystolic heart murmur These general symptoms may also mimic those of infective endocarditis. Complications * Arrhythmias * Pulmonary edema * Peripheral emboli * Spread (metastasis) of the tumor * Blockage of the mitral heart valve * Stroke * Fusiform cerebral aneurysms
