We need to get rid of two misconceptions: Misconception 1: Valve replacement was a major surgery for me, taking a lot of risks and experiencing not only physical pain, but also a heavy mental burden. I still have palpitations after the surgery, and I am still careful to go home and stay out of the house so that my problem will not return. The correct perspective: Valve replacement surgery is a “radical surgery” for valve pathology, and as long as the postoperative rehabilitation program is done well, the valve will last for a long time after surgery. After surgery, patients can resume normal life and work, and those who had poor heart function before surgery, walking and climbing stairs, will find their hearts less burdened and rejuvenated after surgery. Myth 2: Many patients feel that the surgery is successful, their heart valves are clear, all the symptoms they had before the surgery are gone, and they are exactly the same as normal people, so they don’t need to go to the hospital for regular checkups. Correct: Postoperative medication and regular checkups are very important after heart valve replacement! In particular, the use of warfarin after surgery is crucial. Overdose of warfarin may increase the possibility of bleeding such as brain bleeding and stomach bleeding, while underdose may increase the possibility of thrombosis such as pulmonary embolism and cerebral embolism. The human body’s drug metabolism may fluctuate, and the food and drugs taken may also have an effect on the metabolism of warfarin, so regular visits to the hospital are necessary to check the prothrombin time and adjust the warfarin dosage. So remember to go to the hospital for regular check-ups after surgery! We recommend that during the first month after discharge from the hospital, it is advisable to visit the hospital once a week to check the prothrombin time (PT) in order to adjust the warfarin dosage correctly. Later, if the PT is stable, you can gradually extend the periodicity of the outpatient tests. But remember, at least once a month is a must to come to the hospital for PT check!
