Transesophageal echocardiography is the best test to detect the presence of left auricular thrombus, and a number of other tests may be performed to assist in treatment.
In patients with atrial fibrillation, loss of contractile function of the left auricle and blood stasis are the main causes of left auricle thrombosis. Therefore, patients can also have a 24-hour ambulatory electrocardiogram (ECG) to determine atrial fibrillation and ventricular rate, and the elimination of atrial fibrillation is an effective way to prevent left auricle thrombosis.
Slow blood flow, endothelial damage and increased blood coagulation are the three necessary conditions for thrombosis, therefore, blood lipids, coagulation function, liver function, kidney function should also be tested to determine whether the patient has risk factors for thrombosis, and if the patient is a high-risk patient for thrombosis, oral anticoagulant drugs should be taken to prevent thrombosis.
If the patient has left auricular thrombus, atrial fibrillation is usually present. If atrial fibrillation cannot be cured and the patient does not want to take oral anticoagulant drugs, left auricular occlusion can be considered.
Because left auricular thrombus dislodged easily lead to cerebral embolism, should be timely consultation, regular review, under the guidance of the doctor examination and treatment.
