Abstract:
Right atrial diverticulum is a rare congenital cardiac malformation with a very low incidence and few reports in the literature. It is a sac-like structure originating from the free wall of the right atrium or the right auricle，and the wall of the diverticulum is mostly composed of normal myocardial tissue. Patients with diverticulumare asymptomatic in the early stage of the disease，and it is mostly detected by imaging examinations. The patient was a 96-year-old male admitted to the Second Hospital of Hebei Medical University with intermittent chest tightness，shortness of breath，and dizziness for more than half a month. Echocardiography and contrast echocardiography were performed 1 d after the patient was admitted to the hospital，suggesting the diagnasis of right atrial diverticulum with thrombosis，and coronary CT angiography was performed 4 d after the patient was admitted to the hospital，which considered right atrial diverticulum，with an internal filling defect，and suspected thrombus formation. The patient was older and did not receive further diagnosis and treatment，and cardiac ultrasound was repeated 1 month later，with no significant change in the size and morphology of the mass within the right atrial diverticulum. By analyzing in detail a case with right atrial diverticulum initially misdiagnosed as pericardial effusion，this article aimed to raise cardiac sonographers' awareness of the diagnosis of right atrial diverticulum and to explore the key role of cardiac acoustic contrast technology in cardiac ultrasound diagnosis.
