Summary
Mitral valve repair offers reduced operative mortality, long-term mortality, and bleeding in rheumatic heart disease. However, it is associated with a higher reoperation rate, making it a recommended option when feasible.
Area of Science:
- Cardiology
- Cardiac Surgery
- Preventive Cardiology
Background:
- Rheumatic heart disease (RHD) is a leading global cause of heart valve disease.
- Mitral valve repair is preferred for degenerative disease, but its role in RHD is debated.
- This meta-analysis evaluates repair versus replacement for RHD.
Purpose of the Study:
- To compare the outcomes of mitral valve repair and replacement in patients with rheumatic heart disease.
- To assess operative mortality, long-term mortality, reoperation rates, bleeding, thromboembolism, and endocarditis.
Main Methods:
- A systematic search of Medline, EMBASE, Cochrane, and Scopus (1980-2016).
- Inclusion of studies reporting outcomes for both mitral valve repair and replacement in RHD.
- Independent assessment, data extraction, and analysis by two authors.
Main Results:
- 13 studies included 2,410 repairs and 3,598 replacements.
- Repair showed lower operative mortality (3.2% vs 4.3%) and significantly lower long-term mortality (OR 0.41).
- Repair was associated with less bleeding (OR 0.26) but a higher reoperation rate (OR 3.02).
Conclusions:
- Mitral valve repair is linked to reduced operative and long-term mortality and bleeding in RHD.
- Repair is recommended for rheumatic mitral valve disease when technically feasible.
- A higher rate of reoperation is a key consideration with mitral valve repair in RHD.

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
