Abstract: The absence of left atrial appendage ( LAA ) is an extremely rare disease, which is usually diagnosed by chance in imaging examinations before atrial fibrillation surgery. Here, we report a rare case of left atrial appendage loss in a 67-year-old man who planned to undergo radiofrequency catheter ablation of atrial fibrillation. We observed LAA deficiency in transesophageal echocardiography (TEE) and further refined left atrial CTA imaging and cardiac magnetic resonance imaging ( MRI ) to confirm this diagnosis. Since there is no data on anticoagulation in patients with a missing left atrial appendage, we continue to use rivaroxaban anticoagulation per guidelines after successful radiofrequency catheter ablation.
