Hi doctor. I just had heart surgery to repair mitral valve and ligament connection 3 weeks ago and have been discharged from the hospital. After 5 days of surgery, her heart beat stably, but on the 6th day, her heart beat faster every time she walked or sat up. But when I lay down for about 30 minutes, my heart gradually stabilized.

Her mother has tight stenosis, mild mitral regurgitation, mild aortic regurgitation and severe pulmonary hypertension. I would like to consult a doctor for treatment methods for damage to the two heart valves. Thank you!
