Can mitral valve prolapse cause arrhythmias?

Mitral valve prolapse symptoms can vary widely from one person to another. They tend to be mild and develop gradually. Symptoms may include: A racing or irregular heartbeat (arrhythmia)

Which is the most common arrhythmia in patients with mitral valve prolapse?

Ventricular arrhythmias and sudden cardiac death (SCD) have been reported. From a pathological anatomy viewpoint, accumulation of proteoglycans (myxomatous mitral valve) is the most common cause of MVP, accounting for leaflet thickening and redundancy, chordal elongation, interchordal hoodings, and annular dilatation.

When to see an echo for mitral valve prolapse?

Even for those who are not experiencing symptoms, if a murmur is detected suggesting mitral valve prolapse, an echocardiogram, or echo, is usually recommended. The echo uses ultrasound to evaluate the characteristics of the valve cusps and how much blood may be leaking (regurgitation) from the valve when the heart contracts.

Can a prolapsed mitral valve cause a heart murmur?

In some cases, the prolapsed valve lets a small amount of blood leak backward through the valve, which may cause a heart murmur. Watch an animation of mitral valve prolapse. Is mitral valve prolapse dangerous? In most cases, it’s harmless. Most people who have the condition are unaware of it and their health is not affected.

What happens to the mitral valve during MVP?

What is mitral valve prolapse (MVP)? Mitral valve prolapse is a condition in which the two valve flaps of the mitral valve do not close smoothly or evenly, but instead bulge (prolapse) upward into the left atrium. Mitral valve prolapse is also known as click-murmur syndrome, Barlow’s syndrome or floppy valve syndrome. What happens during MVP?

How does LV geometry affect mitral valve prolapse?

Such changes to LV geometry significantly change the spatial relationships between mitral leaflets, papillary muscles, and chordae tendinae. In this example, lateral displacement of the papillary muscles and chordae lead to poor leaflet coaptation and MR from LA dilatation. The resulting MR is centrally directed.
