What is the Mitral Valve?
The mitral valve is located between the left atrium and the left ventricle and is composed of two flaps. Normally the flaps are held tightly closed during left ventricular contraction (systole) by the chordae tendineae (small tendon "cords" that connect the flaps to the muscles of the heart). In Mitral Valve Prolapse (MVP), the flaps enlarge and stretch inward toward the left atrium, sometimes "snapping" during systole, and may allow some backflow of blood into the left atrium (regurgitation).
How is Mitral Valve Regurgitation (including Mitral Valve Prolapse) Treated?
The standard of care for patients with symptomatic Mitral Valve Regurgitation (including Mitral Valve Prolapse) is mitral valve surgery repair or replacement.
What is Mitral Valve Repair?
Mitral valve repair is the best option for nearly all patients with a mitral regurgitation (a leaking valve) and for many with a mitral stenosis (a narrowed valve). Heart valve repair is preferable, because a person's own tissues are used.
Mitral valve repair can be performed minimally invasively and with a catheter (Mitraclip)
What are the advantages of mitral valve repair?
What is Mitral Valve Regurgitation?
Mitral valve regurgitation (MR), also known as a leaking mitral valve, Barlow's syndrome, occurs when one or both of the flaps may not close properly, allowing the blood to leak backward (regurgitation). This regurgitation may result in a murmur (abnormal sound in the heart due to turbulent blood flow). Mitral regurgitation (backward flow of blood), if present at all, is generally mild.
What is Mitral valve Prolapse?
Mitral valve prolapse, also known as click-murmur syndrome, Barlow's syndrome, balloon mitral valve, or floppy valve syndrome, is the bulging of one or both of the mitral valve flaps (leaflets) into the left atrium during the contraction of the heart. One or both of the flaps may not close properly, allowing the blood to leak backward (regurgitation). This regurgitation may result in a murmur (abnormal sound in the heart due to turbulent blood flow). Mitral regurgitation (backward flow of blood), if present at all, is generally mild.
It is estimated that mitral valve prolapse occurs in less than 3 percent of the population.
What is the risk of mitral valve surgery?
For asympotmatic patients undgoing mitral valve surgery, the risk of peri-operative death is significantly less than 1 in 100. Furthermore, after a successful valve repair the need for reoperation is less than 5 in 100 at 20 years
