Brief Answer:
It means that the right upper chamber of your heart is enlarged

Detailed Answer:
Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. Right auricle of atrium is the name of one of the four heart chambers. This chamber gets its input blood supply from the lungs after oxygenation and it pumps the blood in to the left ventricle from where it is supplied to all the organs.

2. Right auricular dilatation refers to a condition where this chamber is severely enlarged.

3. The causes of right auricular dilatation includes the following
(i) raised right ventricular pressures: pulmonary arterial hypertension, cor pulmonale
(ii) valvular disease: tricuspid regurgitation, tricuspid stenosis, Ebstein's anomaly
(iii) atrial septal defect (ASD)
(iv) atrial fibrillation (AF)
(v) dilated cardiomyopathy

4. Your complete echocardiography report will tell the cause of severe right auricular dilatation. Please discuss your condition with the cardiologist and take required treatment.

Wish you a quick recovery.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.
Do write back if you have any doubts.

Regards,
Dr.Vivek
