Mitral Valve Prolapse and Sudden Death Most diagnosed with MVP have an extremely mild form of the condition, which carries no measurable risk. Initial evidence that MVP may be associated with sudden death came mainly from autopsy series.

Can mitral valve prolapse cause sudden cardiac death?

Importance Malignant arrhythmic mitral valve prolapse (MVP) phenotype poses a substantial risk of sudden cardiac death (SCD), and an estimated 26 000 individuals in the United States are at risk of SCD per year.

How common is death from mitral valve prolapse?

“Our analysis confirms the association, and indicates that the incidence of sudden cardiac death in patients with mitral valve prolapse is significant at 14 in 1000 per year,” he says.

Can a leaky heart valve cause sudden death?

With a leaky valve, sometimes not enough blood gets pumped to the rest of the body. Heart valve leakage/regurgitation can force the heart to work harder to do its job. The condition can lead to heart failure, sudden cardiac arrest, and death.

Can heart valve problems cause sudden death?

Sudden death due to valvular heart disease is reported to range from 1% to 5% in native valves and around 0.2%–0.9%/year in prosthesis. The nature of the diseases is varied, from heritable, congenital to acquired. It may affect both genders in multiple age groups.

Can mitral valve prolapse develop suddenly?

Acute mitral valve regurgitation develops quickly and can be life-threatening. It happens when the valve or nearby tissue ruptures suddenly. Instead of a slow leak, blood builds up quickly in the left side of the heart.

Is heart valve disease fatal?

For some people, the condition mostly stays the same throughout their lives and doesn’t cause any problems. For other people, heart valve disease slowly worsens until symptoms develop. If not treated, advanced heart valve disease can cause heart failure, stroke, blood clots, or death due to sudden cardiac arrest (SCA).

What causes mitral regurgitation?

A tear can cause leakage through the mitral valve suddenly and may require repair by heart surgery. Trauma to the chest also can rupture the cords. Rheumatic fever. Rheumatic fever — a complication of untreated strep throat — can damage the mitral valve, leading to mitral valve regurgitation early or later in life.

Does mitral valve regurgitation increase the risk of death?

Patients with mitral valve prolapse and significant mitral valve regurgitation have an increased risk for sudden cardiac death, estimated at 0.9 to 1.9 percent annually, which is far greater than patients with only mitral valve prolapse or the population as a whole.10,11.

Does mitral valve prolapse predict sudden cardiac death in young females?

Reported cases of isolated mitral valve prolapse and sudden cardiac death indicate that young females with bileaflet redundant leaflets are predominantly affected. Clinical predictors of sudden cardiac death in isolated mitral valve prolapse are lacking.

What is the incidence of mitral valve disease (MVP) in the US?

The incidence of SCD with MVP was estimated at 217 events per 100 000 person‐years. Isolated MVP and SCD predominantly affects young females with redundant bileaflet prolapse, with cardiac arrest usually occurring as a result of ventricular arrhythmias.

What is a systolic murmur with mitral valve prolapse?

This may be accompanied by a systolic murmur in the presence of significant mitral valve regurgitation. On echocardiography, mitral valve prolapse occurs when one or both leaflets protrude greater than 2 mm beyond the annulus into the left atrium during systole in the parasternal long axis and/or apical four chamber views. 1,7
