Summary
Pregnancy with valvular heart disease (VHD) poses risks, especially with regurgitant lesions. This study found significant maternal morbidity in pregnant individuals with VHD, highlighting the need for careful cardio-obstetric management.
Area of Science:
- Cardiology
- Obstetrics
- Maternal-Fetal Medicine
Background:
- Valvular heart disease (VHD) during pregnancy is linked to substantial maternal and fetal complications.
- Limited data exists on contemporary cardio-obstetric risks associated with various VHD types.
Purpose of the Study:
- To describe maternal, obstetric, and fetal outcomes in pregnancies complicated by moderate to severe VHD.
- To identify specific risks associated with different types of valvular heart disease during pregnancy.
Main Methods:
- Retrospective cohort study of pregnancies between 2010-2021.
- Included adult patients with moderate to severe native VHD and/or prior valve interventions.
- Analyzed outcomes including pre-eclampsia, heart failure hospitalizations, preterm delivery, C-section, and NICU admission.
Main Results:
- Out of 242,066 pregnancies, 89 (0.04%) had clinically significant VHD.
- Regurgitant lesions (AR/MR) were most prevalent, associated with higher rates of pre-eclampsia and C-sections.
- Stenotic lesions (AS/MS) were linked to heart failure hospitalizations, preterm delivery, and NICU stays.
Conclusions:
- Left-sided valvular regurgitant lesions during pregnancy are associated with significant maternal morbidity.
- Both regurgitant and stenotic VHD lesions require careful management during pregnancy.
- This study provides contemporary data to guide cardio-obstetric risk assessment for VHD patients.

500
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...

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

404
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...

484
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...

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...
