The anatomical function of the heart valves is like the need to enter and exit the home every day in our daily life. When the door of the home appears to be open, closed or not closed properly, it is bound to be a major problem in the home and must be repaired or replaced in order to restore the function of the door. Likewise, regardless of the cause as long as mechanical functional damage to the valves such as valve stenosis or insufficiency occurs, rather than functional insufficiency due to heart enlargement, such mechanical valve stenosis and insufficiency cannot be restored to its original structure and function by pharmacological treatment. Although some drugs can reduce or eliminate the patient’s symptoms by adjusting the heart’s rhythm, increasing or decreasing the heart’s contractile function, and regulating the resistance of the peripheral vessels to achieve an optimal hemodynamic balance under pathological conditions, none of the drugs can treat the valve itself, neither opening the stenotic orifice nor restoring the function of the incompetent valve. . On the other hand, the valve lesion will continue to develop, and after a period of time, either because of exertion or because of emotional stress, a new imbalance will appear and clinical symptoms will reappear. When the valve lesion is severe enough, it must be treated surgically in order to restore the function of the valve, and only when the function of the valve is restored, the function of the heart can be restored and the patient can regain health and vitality. Restoring the function of the heart valves through surgery has become a common method of treating valve disease. Heart valve insufficiency is divided into two main types of mitral valve insufficiency and aortic valve insufficiency. Common medical causes of mitral valve insufficiency include wind heart disease, mitral valve prolapse, coronary artery disease, tendon rupture, mitral annulus and subannular calcification, infective endocarditis, significant enlargement of the left ventricle, and congenital malformations. Aortic valve closure insufficiency is mostly seen in wind heart disease, congenital malformations, aortic valve mucinous degeneration, infective endocarditis, trauma, aortic coarctation, prosthetic valve rupture, ankylosing spondylitis, both of which have a common feature in the development of the disease course, that is, a long period of cardiac function compensation, patients can have no obvious clinical symptoms for a long time, and patients with early symptoms can also be relieved by drug therapy for a short period of time These symptoms often cause patients to believe that their lesions are mild and that they can continue conservative treatment. According to clinical statistics, more than 40% of patients currently have a fear of heart surgery because they are influenced by the traditional medical concept that heart surgery is costly and has poor surgical results and high mortality, thus they often miss the best time for surgery and have serious consequences, and a significant proportion of them die suddenly as a result. The authors recently encountered such a case: a 60-year-old female patient, a year ago that has mild chest tightness, weakness symptoms, performed cardiac ultrasound shows moderate mitral regurgitation, left ventricular thickening, left atrial hypertrophy, left ventricular ejection fraction decreased, the doctor recommended mitral valve replacement surgery, but the patient took cardiac and diuretic drugs, the symptoms were significantly reduced, coupled with the traditional medical concept of fear of heart surgery, so they chose to continue conservative treatment. One year later, his symptoms worsened significantly, and he developed atrial fibrillation and cerebral infarction with hemiplegia caused by thrombosis, and his heart ultrasound showed that the left ventricle was significantly enlarged and the ejection fraction of the left ventricle decreased significantly. After he came to our department, he said, “I am very determined now, even if I may die on the operating table, I still want to do it. The problem is that determination alone is not the answer. This surgery was enough for about 50,000 yuan two years ago, but now it is estimated to be 150,000 to 200,000 yuan due to the increased difficulty of the surgery, and doctors are afraid to do it. Now we are conditioning his physical condition to see if there is a possibility to fight for the opportunity of surgery. The success rate of early elective surgery is 99%, and most patients can recover their heart function 3-6 months after surgery, and can do many things after surgery that they could not do before surgery, and have a good quality of life. If the heart disease enters the decompensated stage, the success rate of the operation is only 50-80%, even if the operation period is safely passed, it takes a long time to recover after the operation, and even some patients’ heart function cannot be completely restored to normal. I hope people can establish the concept of “early detection, early diagnosis and early treatment” to give themselves and their doctors a chance.
