Aortic and Mitral Valve Disease and Left Ventricular Dysfunction in Children

Area of Science:

• Cardiology
• Valvular Heart Disease

Background:

• Aortic and mitral valve diseases impose significant hemodynamic burdens, affecting patient quality of life and longevity.
• Management requires balancing medical interventions with surgical timing, which is complex in pediatric cases.

Purpose of the Study:

• To review the etiology, anatomy, pathophysiology, presentation, and treatment of aortic stenosis, aortic regurgitation, mitral regurgitation, and mitral stenosis.
• To outline age- and lesion-specific treatments for valvular heart disease based on severity.
• To emphasize long-term preservation of left ventricular function.

Main Methods:

• Literature review of MEDLINE and PubMed databases.
• Synthesis of current understanding of aortic and mitral valve disease management.

Main Results:

• Discussion of four primary valve conditions: aortic stenosis, aortic regurgitation, mitral regurgitation, and mitral stenosis.
• Outline of treatment strategies tailored to disease severity and patient age.
• Focus on maintaining left ventricular function as a key treatment goal.

Conclusions:

• Effective management of mitral and aortic valve disease hinges on appropriate medical care and timely surgical intervention.
• Pediatric patients present unique challenges due to early disease onset, growth considerations, and altered hemodynamic tolerance.
• Guidelines for adult management require adaptation for pediatric populations to optimize outcomes.
