Mitral valve repair surgical procedure
Mitral valve repair surgery is a common procedure used to treat certain types of mitral valve disease. This heart condition affects the valve that allows blood to flow from the left atrium into the left ventricle, and can lead to complications such as regurgitation.
The heart contains four chambers: the right atrium, left atrium, right ventricle, and left ventricle. Mitral valve disease is a collection of conditions that can damage this vital valve. There are two main types of mitral valve disease: mitral valve regurgitation and mitral valve stenosis.
Mitral valve repair surgery may involve a variety of techniques, depending on the type and severity of the disease. The three main types of mitral valve repair surgery are annuloplasty, leaflet resection, and chordal repair.
Annuloplasty involves a surgeon sewing a synthetic ring around a person's mitral valve to help strengthen and tighten the valve. Leaflet resection involves removing the damaged section of a person's mitral valve, while chordal repair involves replacing damaged chordae, which are thick, fibrous cords that connect the mitral valve leaflets to the heart muscle.
Mitral valve surgery is generally low risk, with a mortality rate of 1-2%. However, complications can occur, including bleeding, infection, respiratory failure, kidney failure, stroke, sepsis, blood clots, arrhythmia, endocarditis, and other issues.
Research from 2020 found that minimally invasive mitral valve surgery (MIMVS) was successful in 95.8% of cases. Recovery time may be shorter for people who have MIMVS or percutaneous mitral valve repair.
In centers with surgeons who are experts in mitral valve repair surgery, success rates may be over 90% or close to 100%. If a person has a mitral valve repair early enough, they have a life expectancy similar to someone the same age who does not have mitral valve disease.
It's important to note that patients with mitral valve prolapse (MVP) and a related condition called mitral annular disjunction (MAD) who undergo mitral valve surgery have a three-fold increased long-term risk of ventricular arrhythmias (VA), such as sustained or non-sustained ventricular tachycardia or high burdens of premature ventricular complexes. This increased risk persists despite surgical correction of MAD and applies regardless of whether the valve is repaired or replaced.
The recovery process after mitral valve repair surgery typically involves a hospital stay of around 4-7 days, depending on individual factors. Early post-op recovery focuses on pain control, wound care, and gradual mobilization. Cardiopulmonary rehabilitation may be recommended to improve cardiovascular fitness and function. Regular follow-up with echocardiography is necessary to monitor valve function and detect complications such as recurrent mitral regurgitation or arrhythmias. Long-term antibiotic prophylaxis decisions may be individualized given the lower but present risk for infective endocarditis post-repair.
In summary, patients who undergo mitral valve repair tend to have a favorable long-term risk profile for infections but need monitoring for arrhythmias, especially if they had mitral annular disjunction. Recovery involves hospital care, rehabilitation, and routine cardiac monitoring over years after surgery to ensure valve integrity and cardiac rhythm stability.

- The field of science continues to advance, with research in cardiovascular health and medical-conditions like heartvalve disorders playing a significant role in improving surgical techniques for treating mitral valve diseases, such as mitral valve repair surgery.
- The importance of maintaining one's health and wellness cannot be overstated, particularly in relation to heartvalve disorders, as early detection and treatment can lead to a life expectancy comparable to those who do not have such medical conditions, with mitral valve repair surgery being a crucial step in preserving cardiovascular health.
