My mother has MR and AF for many years. Is her condition getting worse?

Hi doctor,

My mother was diagnosed with mitral valve regurge and atrial fibrillation before many years. She is taking Dilatrend twice a day with vitamins. She is 65 years old now and done an ECHO every six to nine months. For the past three years, she has the following ejection fraction. She had an EF of 55 percent before two years and it became 73 percent last year. It came back to 58 percent this year. On the left atrium, the ejection fraction was 55 percent before two years, 69 percent last year, and back to 54 percent this year. The left atrium to aorta ratio was 1.7 before two years back and came to 2.09 last year. It came back to 1.8 this year. The other parameters remained the same with a constant grade of two to three mitral regurge with a regurge fraction ranging between thirty-one to thirty-six, in grade two tricuspid regurge, trivial aortic and pulmonary regurge. The RVSP on the other hand got increased from 52 mmHg (before two years) to 78 mmHg this year. Did these things seem to be better due to the higher ejection fraction? Her visible symptoms have not changed with the exception that she is getting tired sooner and has a feeling of anxiety or weakness periodically.
