What Is Tricuspid Valve Replacement?
Valve replacement is to replace a diseased valve with a functioning one. It is mainly used for cases where the heart's valve cannot be corrected by medically conservative methods, such as mitral valve replacement, aortic valve replacement, or double valve replacement. Valve replacement and so on.
Valve replacement
- In humans, there are valves in the heart and large blood vessels. Their role is to ensure the one-way flow of blood flow, that is, the centrifugal direction of arterial blood, and the venous blood flows to the heart. If the valve is damaged, this blood flow will be disturbed. Causes human illness. The ideal valve has good compatibility with the human body, no mechanical failure, no thrombus, etc. At present, mechanical valves and biological valves used in clinical practice have certain defects. The former requires lifelong anticoagulation, noise, and possible mechanical failure. The latter has a limited service life.
- Mitral stenosis
- If the leaflet movement is good, only the junction adhesion or mild subvalvular damage, you can strive for closed expansion or open-sight angioplasty. If valve calcification or funnel-like changes, valve replacement surgery is required;
- Mitral regurgitation
- Those with an enlarged mitral valve annulus or limited leaflet curl at the junction can seek open-sight plastic surgery. Leaflet perforation, chordae rupture, etc., if the plastic surgery is difficult to completely correct or the plastic surgery fails, mitral valve replacement surgery should be implemented. Mitral stenosis with mitral regurgitation, most require valve replacement;
- 3. Tricuspid valve damage: Usually tricuspid valve is not replaced. Valve replacement is performed only when the lesion is severe;
- Aortic stenosis
- Congenital aortic valve stenosis can often be performed by open-sight incision in adolescents. Middle-aged and elderly aortic valve stenosis is mostly caused by calcification based on congenital aortic valve bivalvular deformity. Need for heart valve replacement-aortic valve replacement;
- Aortic insufficiency
- Aortic valve insufficiency can be caused by annulus enlargement, leaflet tearing and perforation, curling or prolapse, etc. Usually, heart valve replacement should be performed. Plastic surgery is only possible with mild prolapse of the aortic valve;
- 6. Pulmonary valve disease: mostly congenital malformations, rarely requiring valve replacement, often with a right ventricle-pulmonary bypass with valved ducts.
- Patients can compare the common indications for heart valve replacement according to their own conditions to decide whether they need heart valve replacement.
Preoperative valve replacement care
- Preoperative care of cardiopulmonary bypass open heart surgery, and to clarify anticoagulation knowledge and its significance to patients and their families.
Nursing after valve replacement
- Nursing after open heart surgery with extracorporeal circulation.
- 1. Special attention is paid to the prevention of early postoperative arrhythmias.
- 2. Correct and reasonable use of antibiotics after nursing infections.
- 3. The prothrombin time is measured in the morning on the 3rd day after the anticoagulation nursing, and the prothrombin time is required to be maintained at 1.5-2 times the normal value. Patients who replace mechanical valves must take anticoagulants for life. Pay attention to the following points:
- (1) During the hospital stay, the nurse should record the daily prothrombin time and the oral warfarin dose. At the same time, the patient should prepare a small record book to help find out the medication rule, and let the patient try to take it for him to develop. Get used to it and record it for life.
- (2) Oral warfarin should master the principle of regular quantitative and accurate dosage.
- (3) Pay attention to signs of excessive anticoagulation: such as hematuria, nosebleeds, subcutaneous hemorrhage, bleeding gums, occult blood in stool, etc. If the above symptoms occur, generally reduce or discontinue the drug for 1 day.
- (4) Observe the presence or absence of thrombosis, pay attention to the patient's consciousness, limb movements, and contact the physician in time if abnormalities are found in order to adjust the dose of anticoagulant drugs.
Valve replacement health guidance
- 1. Take warfarin anticoagulant in a regular amount.
- 2. Regular follow-up visits to the outpatient clinic every 2 weeks after discharge and once every 4 weeks after 3 months; if the prothrombin time is unstable, the prothrombin time should still be measured 1-2 times a week.
- 3, rest for six months after being discharged from the hospital to avoid excessive activity and fatigue. However, the amount of activity can be gradually increased.
- 4, diet pay attention to nutrition.
- 5. Take strong diuretics as prescribed by your doctor. Avoid taking medications that affect prothrombin time. [1]
