Valve aortique

Sténose aortique

Traitement

Valve mitrale

Insuffisance mitrale

Synonyme: régurgitation mitrale

Primaire

• Chronic primary mitral regurgitation relates to processes involving any portion of the mitral annulus. Common causes of primary mitral regurgitation are mitral valve prolapse (also known as myxomatous or degenerative mitral valve disease), radiation therapy, rheumatic disease, and cleft mitral valve.

Secondaire

• Chronic secondary mitral regurgitation involves causes other than the annulus, such as ventricular dysfunction.

Traitement

• Mitral valve repair is strongly recommended for chronic severe primary mitral regurgitation in
  • symptomatic patients with left ventricular ejection fraction greater than 30%
  • asymptomatic patients with left ventricular dysfunction
  • and patients undergoing another cardiac surgical procedure.
• Insuffisance mitrale aiguë: ballonnet intra-aortique
