Valve aortique
Sténose aortique
Traitement
- Chirurgie de remplacement de la valve aortique
- TAVI
- Traitement médicamenteux: diminution de la post-charge. Vasodilators should be used with caution in patients with aortic stenosis and heart failure symptoms.
Valve mitrale
Sténose mitrale
- Medical therapy for mitral stenosis consists of diuretics or long-acting nitrates, which may help alleviate symptoms such as dyspnea. In addition, β-blockers or nondihydropyridine calcium channel blockers can lower heart rate and improve left ventricular diastolic filling time.
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.[1]
Secondaire
- Chronic secondary mitral regurgitation involves causes other than the annulus, such as ventricular dysfunction.[1]
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 à contrepulsion
