It is believed that many patients with heart valve disease struggle with the choice of a prosthetic valve once they have been determined to have a replacement valve. The choice of prosthetic valve is of great significance to the patient’s quality of life after surgery. There are two main types of prosthetic valves: mechanical and biologic, so how do you choose the most appropriate prosthetic valve for you? Biologic valves are recommended for 1) elderly patients older than 60 years of age with a flush heart rhythm and no atrial fibrillation, especially for patients older than 65 years of age. 2, Patients of childbearing age who wish to have children after surgery. Although it is still possible to attempt to apply heparin instead of warfarin for pregnancy after replacement of the mechanical valve, there is still a risk of malformation and bleeding and embolism, though. Therefore, women preparing to become pregnant after flap replacement may opt for a biologic flap. 3. Biologic flaps are recommended for patients with bleeding tendencies. This includes patients with bleeding qualities, bleeding disorders, and other reasons for not receiving long-term anticoagulation therapy. 4, Biologic flaps are recommended for patients who are unable to undergo anticoagulation due to geographic or condition restrictions. 5, Patients of any age who are unwilling to take long-term anticoagulants for various reasons and who can accept reoperation after a bad biological flap. The recommended patients for mechanical valves are 1, younger patients under 60 years of age with no contraindications to anticoagulation, especially patients with preoperative persistent atrial fibrillation and multivalvular lesions. 2, Patients who are not suitable for implantation of a bioprosthetic valve. For example, patients with small aortic root, or small left ventricle, the left ventricular outflow tract is not wide, in this case mitral valve position implantation of biological valve can often lead to secondary stenosis of the left ventricular outflow tract, the use of mechanical valve is recommended. Doctor’s Note The choice of prosthetic valve is very important as it affects the patient’s postoperative lifestyle and the long-term outcome of the procedure. The choice of valve is not absolute, but can be based on the respective characteristics of the bioprosthetic and mechanical valves, combined with your own physical condition and lifestyle needs, and the advice of your doctor before making the most suitable choice.
