Left atrium 43mm is usually the result obtained by measuring the anteroposterior diameter of the left atrium under cardiac ultrasound examination. 43mm anteroposterior diameter of the left atrium is abnormal, which means that the left atrium is enlarged.
During a cardiac ultrasound, the normal value of the anteroposterior diameter of the left atrium is 30-40 mm for men and 27-38 mm for women. 43 mm of the anteroposterior diameter of the left atrium, regardless of the gender, is abnormal, indicating that the patient has left atrial enlargement.
Left atrial enlargement can be seen in atrial septal defect, ventricular septal defect, mitral stenosis, mitral valve insufficiency, hypertension, hypertrophic cardiomyopathy, dilated cardiomyopathy, persistent atrial fibrillation, coronary artery disease and other diseases.
If the anteroposterior diameter of the left atrium is found to be 43mm, please follow the doctor’s instructions to improve the follow-up examination and treatment.
