Moderate to severe
mitral regurgitation is a disease of the heart valves. Normally, the mitral valve prevents blood from flowing back from the left ventricle to the left atrium during systole. However, when moderate and severe regurgitation occurs, a large amount of blood will rush back to the left atrium when the left ventricle contracts. This condition can trigger a series of symptoms. Patients may experience expiratory dyspnoea, especially during physical activity or when lying down, because pulmonary venous return is blocked, causing congestion in the lungs. The patient may also experience fatigue, palpitation, and edema, as the heart is affected and unable to effectively pump blood throughout the body, resulting in inadequate blood supply to all parts of the body.
Etiologically, mitral regurgitation may be due to leaflet disease, annular enlargement, chordae tendineae, or papillary muscle dysfunction. For example, rheumatic heart disease can damage the leaflets and chordae tendineae of the mitral valve, while myocardial infarction may lead to abnormal papillary muscle function, which can lead to mitral regurgitation.
For the treatment of moderate and severe mitral regurgitation, it is necessary to consider the patient’s age, physical condition, severity of symptoms and other factors. Drug therapy is mainly used to improve symptoms and heart function, such as the use of diuretics to reduce edema, angiotensin-converting enzyme inhibitors (ACEI) to reduce heart load. Surgical treatment, such as mitral valve repair or mitral valve replacement, can also be considered to improve regurgitation by repairing or replacing the diseased mitral valve when physical conditions permit.
A
mitral clamp is a medical device used to treat mitral regurgitation. It delivers the clamping device to the mitral valve lesion through a catheter by means of minimally invasive intervention. Mitral valve regurgitation can increase the burden on the heart and affect the function of the heart. Mitral valve clamp can effectively improve regurgitation, reduce abnormal blood reflux, reduce heart load, alleviate symptoms of patients, improve quality of life, and bring new hope for some patients who are not suitable for or refuse traditional thoracotomy.
During
the procedure, the surgeon utilizes a special delivery system to accurately place the mitral clamp. This technology has the advantages of small trauma and quick recovery. Compared with traditional cardiac surgery, it avoids the greater risk of thoracotomy and extracorporeal circulation. Mitral clamp can precisely clamp the mitral valve leaflet and reshape the structure and function of the mitral valve. The symptoms of heart failure in patients after operation can often be significantly improved, such as expiratory dyspnoea, fatigue and other conditions, and the hospitalization time is relatively short, so they can return to normal life more quickly. At the same time, this technology is constantly improving and developing to provide better treatment options for more patients with mitral valve disease.
In the long run, the mitral valve clamp can stabilize the hemodynamic state of the heart to a great extent. It reduces the possibility of a series of serious complications such as arrhythmia and cardiac enlargement caused by the long-term existence of mitral regurgitation. In terms of adaptation to the population, it is mainly suitable for patients with moderate to severe mitral regurgitation who are elderly, have a variety of complications and have poor surgical tolerance. However, before using the mitral clamp, a comprehensive and detailed evaluation, including cardiac ultrasound and other tests, is needed to determine whether the patient is suitable for this treatment. With the further development of medical technology, the operation technology related to mitral valve clamp is becoming more and more popular. More medical centers can carry out this treatment, which brings good news to patients with mitral valve regurgitation worldwide and greatly improves the prognosis and living conditions of this group of patients.
