1. Symptoms of atrial fibrillation
Symptoms of atrial fibrillation often manifest when changing positions include: shortness of breath when lying flat, chest pain, feeling of tightness in the chest, dizziness, palpitations, sometimes fainting.
2. Causes and risk factors
Atrial myxoma is a primary tumor that originates in the heart, unlike other tumors that often originate elsewhere, metastasize to the heart via the hematogenous route or invade the heart from nearby areas.
Primary cardiac tumors are rare and mucinous tumors are the most common. Most of the atrial myxomas are found in the left atrium, usually with peduncles arising from the atrial septum, the rest are rare in the right atrium.
Atrial fissures are more common in women. About 10% of myomas are familial; in these individuals, the tumor is more common in multiple locations in the heart and presents with symptoms in younger patients.

3. Diagnosis of atrial myxoma
Your doctor may order tests such as an electrocardiogram, echocardiogram, cardiac CT scan, or cardiac MRI to make a diagnosis.4. Complications of atrial myxoma
Although atrial myxoma is a benign tumor, it is a dangerous tumor because it is located in the heart. If left untreated, the tumor will cause many complications, including: the tumor may burst, drift with the blood stream and cause embolism in other parts of the body such as cerebral embolism, visceral embolism, limb embolism. Especially if the tumor presses on the mitral valve opening, causing obstruction of blood flow through the mitral valve, it can cause fainting or even sudden death for the patient.
