One out of eight people over the age of 75 suffers from moderate to severe heart valve disease which involves damage to one or more of the heart’s valves. While some types are not serious, others can lead to major complications—including death.

What is regurgitation?


Regurgitation is when a valve does not fully close and allows blood to leak backwards. It is also commonly referred to as valve insufficiency, or a leaky valve. This condition includes mitral regurgitation and aortic regurgitation.

What is stenosis?


Stenosis is when a valve does not fully open to allow enough blood to flow through. This can be due to age-related calcification of the valve. A calcified valve can become very narrow or blocked and therefore limits the amount of blood that flows through. It is also commonly called a sticky, narrowed, or stiff valve.
