Summary
Percutaneous Balloon Mitral Valvotomy (PBMV) is a safe and effective treatment for severe rheumatic mitral valve stenosis in pregnant women. This procedure significantly reduces pressure and gradient across the mitral valve, leading to good fetal outcomes.
Area of Science:
- Cardiology
- Obstetrics
- Interventional Cardiology
Background:
- Rheumatic mitral valve stenosis is a common valvular abnormality in pregnant women.
- Severe mitral valve stenosis can lead to heart failure during pregnancy, posing risks to both mother and fetus.
Purpose of the Study:
- To evaluate the fetal outcomes of pregnant patients with severe rheumatic mitral valve stenosis who underwent Percutaneous Balloon Mitral Valvotomy (PBMV).
- To assess the safety and efficacy of PBMV during pregnancy.
Main Methods:
- Retrospective study of pregnant patients with severe rheumatic mitral valve stenosis who underwent PBMV.
- Data collected from medical records at a tertiary referral center.
- Follow-up conducted via phone calls and office visits.
Main Results:
- PBMV was performed on 24 pregnant patients, with 100% procedural success.
- Significant reductions observed in pulmonary artery pressure and transmitral valve gradients post-procedure.
- Good fetal outcomes were reported in most cases, with two infants experiencing mortality due to heart failure.
Conclusions:
- Percutaneous Balloon Mitral Valvotomy is a relatively safe and effective procedure for managing severe rheumatic mitral valve stenosis during pregnancy.
- The procedure leads to significant hemodynamic improvements and generally favorable fetal outcomes.

The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

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. Timely...

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...

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...

1.1K
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...
