Hello dear, Thank you for your question. In my opinion, the bronchitis needs to be treated with antibiotics and cough syrup. I always suggest my patients to drink plenty of water, in order to alleviate the passing of the secretions. Your doctor will examine your lungs with a stethoscope and may also request a chest X-ray. He or she will be able to prescribe therapy accordingly. Please do not underestimate the treatment of bronchitis, which is particularly important in your case, since CHF has started. I think you are scheduled for a transesophageal heart ultrasound, so your doctor can evaluate the state of your mitral valve before the operation. It maybe uncomfortable to have the examination while having bronchitis. Therefore, if it is possible, I would advise to postpone the procedure. I hope this helped. Kind regards, Dr. Alma
