Mitral Valve Prolapse

Overview

Epidemiology

• Most common cardiac valve anomaly
• Affects 3%–7% of the global population
• Women > men 
• Most common between 15–30 years of age
• Complications are more often seen in men.

Etiology

• Primary/ idiopathic Idiopathic Dermatomyositis (most common)
• Secondary:
  • Connective tissue Connective tissue Connective tissues originate from embryonic mesenchyme and are present throughout the body except inside the brain and spinal cord. The main function of connective tissues is to provide structural support to organs. Connective tissues consist of cells and an extracellular matrix. Connective Tissue: Histology disorders:
    • Marfan’s syndrome 
    • Ehlers-Danlos syndrome Ehlers-Danlos syndrome Ehlers-Danlos syndrome (EDS) is a heterogeneous group of inherited connective tissue disorders that are characterized by hyperextensible skin, hypermobile joints, and fragility of the skin and connective tissue. Ehlers-Danlos Syndrome 
    • Osteogenesis imperfecta Osteogenesis imperfecta Osteogenesis imperfecta (OI), or “brittle bone disease,” is a rare genetic connective tissue disorder characterized by severe bone fragility. Although OI is considered a single disease, OI includes over 16 genotypes and clinical phenotypes with differing symptom severity. Osteogenesis Imperfecta
    • Pseudoxanthoma elasticum
  • Cardiac abnormalities:
    • Atrial septal defect Atrial Septal Defect Atrial septal defects (ASDs) are benign acyanotic congenital heart defects characterized by an opening in the interatrial septum that causes blood to flow from the left atrium (LA) to the right atrium (RA) (left-to-right shunt). Atrial Septal Defect (ASD)
    • Hypertrophic cardiomyopathy Hypertrophic Cardiomyopathy Hypertrophic cardiomyopathy (HCM) is the most commonly inherited cardiomyopathy, which is characterized by an asymmetric increase in thickness (hypertrophy) of the left ventricular wall, diastolic dysfunction, and often left ventricular outflow tract obstruction. Hypertrophic Cardiomyopathy

Pathophysiology

Mitral valve Mitral valve The valve between the left atrium and left ventricle of the heart. Heart: Anatomy prolapse (MVP) is the bulging of the mitral valve Mitral valve The valve between the left atrium and left ventricle of the heart. Heart: Anatomy (MV) leaflets into the atrium by ≥ 2 mm above the plane of the MV annulus during ventricular systole Ventricular systole Cardiac Cycle:

• Most commonly characterized by myxomatous degeneration (Barlow’s syndrome): accumulation of glycosaminoglycans (GAGs) and alterations in collagen Collagen A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of skin; connective tissue; and the organic substance of bones (bone and bones) and teeth (tooth). Connective Tissue: Histology structure → expansion of the spongiosa layer of the MV leaflets and chordae tendineae Chordae tendineae The tendinous cords that connect each cusp of the two atrioventricular heart valves to appropriate papillary muscles in the heart ventricles, preventing the valves from reversing themselves when the ventricles contract. Heart: Anatomy leading to:
  • Thickened, stretchy leaflets with excess tissue
  • Elongated chordae tendineae Chordae tendineae The tendinous cords that connect each cusp of the two atrioventricular heart valves to appropriate papillary muscles in the heart ventricles, preventing the valves from reversing themselves when the ventricles contract. Heart: Anatomy (rupture less common)
  • MV annulus enlargement
  • Endothelial disruption of the MV leaflets → possible sites for endocarditis Endocarditis Endocarditis is an inflammatory disease involving the inner lining (endometrium) of the heart, most commonly affecting the cardiac valves. Both infectious and noninfectious etiologies lead to vegetations on the valve leaflets. Patients may present with nonspecific symptoms such as fever and fatigue. Endocarditis and thrombus formation
• Fibroelastic deficiency is another potential cause (usually older patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship): ↓ collagen Collagen A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of skin; connective tissue; and the organic substance of bones (bone and bones) and teeth (tooth). Connective Tissue: Histology, elastin, and proteoglycans Proteoglycans Glycoproteins which have a very high polysaccharide content. Basics of Carbohydrates leads to:
  • Thin leaflets, no excess tissue
  • Some annulus dilation
  • Thin, elongated chordae → ↑ risk of rupture

Cardiac Cycle → mild MR MR Calculated as the ratio of the total number of people who die due to all causes over a specific time period to the total number of people in the selected population. Measures of Health Status
  • Ruptured chordae tendineae Chordae tendineae The tendinous cords that connect each cusp of the two atrioventricular heart valves to appropriate papillary muscles in the heart ventricles, preventing the valves from reversing themselves when the ventricles contract. Heart: Anatomy → flail leaflets → severe MR MR Calculated as the ratio of the total number of people who die due to all causes over a specific time period to the total number of people in the selected population.
