Summary
Acute mitral regurgitation in infants, often due to chordae tendineae rupture, is increasingly reported. Early diagnosis and mitral valve repair are crucial to prevent infant death from cardiogenic shock.
Area of Science:
- Pediatric Cardiology
- Cardiac Surgery
- Neonatal Medicine
Background:
- Acute mitral regurgitation (AMR) in infants was considered rare but is now increasingly recognized.
- Rupture of the chordae tendineae is a primary cause of AMR, particularly noted in Japan.
Observation:
- Infants presenting with sudden cardiorespiratory collapse may have undiagnosed AMR.
- Delayed diagnosis or treatment can lead to severe outcomes, including cardiogenic shock and mortality.
Findings:
- Early diagnosis is critical for managing AMR in infants.
- Mitral valve repair is the preferred treatment for moderate to severe AMR when feasible.
Implications:
- Pediatricians and cardiac specialists must consider AMR in infants with acute cardiorespiratory distress.
- Pediatric cardiac surgeons require specialized skills in mitral valve repair and replacement techniques, including supraannular approaches.

1.1K
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 regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...

Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1.

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 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...

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
