My mother is undergoing surgery to have a mechanical heart valve. What is the lifespan of a mechanical heart valve?

Dr. Allen Raczkowski

Mechanical heart valves are made of a substance called pyrolytic carbon, which is similar to industrial grade diamond. It is very hard and wears very little.

These valves are tested for durability by making the valve open and close over and over again like in the heart (about the same number of heart beats if you lived 100 years!) and show almost no wear.

Although mechanical failure is extremely unlikely, there are other problems like infection that could require further surgery. This is also very unlikely if the patient follows the American Heart Association's recommendations.

Dr. Allen Raczkowski practices Cardiothoracic Surgery and General Surgery at Banner Heart Hospital in Mesa, Arizona. Renowned as the world's leading robotic cardiac surgeon, Dr. Raczkowski uses a special technology, the Da Vinci robot, which enables him to perform delicate procedures such as valve repairs and coronary artery surgery, producing better results, and offering patients a better quality of life in much less time than traditional heart surgery. Dr. Raczkowski graduated from the Wayne State University School of Medicine with an MD and has been in the profession for over 30 years. Visit him online at www.bannerhealth.com.

Is there an ideal time off (respite) for caregivers that I can show my sisters to help my case for getting time off?

I have never seen an official “Required Respite Time” statistic because of course there are so many factors and it’s very individual, but I would boil the need for respite down to this: As often as needed!
