Physical effects of heart valve disorders

Physical effects include regurgitation and stenosis.

Regurgitation

Regurgitation occurs when blood:

  • flows back into the valve as it closes
  • leaks through the valve’s flaps after they’re closed

This condition causes the heart to work harder to pump the same amount of blood.

Stenosis

Stenosis is the narrowing of a valve opening that decreases blood flow through the valve. This increases the risk of blood clots and causes the heart to work harder.

Increased risk effects of heart valve disorders

If a heart valve disorder goes untreated, you may be at risk of:

  • stroke
  • blood clots
  • heart failure 
  • death due to sudden cardiac arrest, which is when your heart stops
