“I couldn’t be more pleased….”

It's been 14 months since my aortic valve replacement and implant of the On-X mechanical valve.  I couldn't be more pleased with the results.  In the last year, I've averaged walking 3-4 miles per day only missing a few days here and there on account of rain.  Even during this cold winter and last year, […]

“I wanted the best….”

When I was told that I needed surgery to repair aneurysm on my Acending Aorta, I was extremely nervous to say the least. I then found that I had a bicuspid valve and that too needed to be replace. I was in the military so I really was at the mercy of what ever the […]


After 14 years of watchful waiting, four years after a mitral balloon valvuloplasty, I could no longer hit my golf ball and walk to it without becoming breathless. A stress echo showed it was time to replace my diseased and leaking mitral valve.  There was no doubt in my mind that I would have an […]

Aortic Aneurysm Success Story

“When my cardiologist indicated it was time for me to surgically address my ascending aortic aneurysm and degrading aortic valve, I undertook some research into what would be my best choice. I did not want to face the prospect of another open heart procedure when in my 80s, as would probably be required if I […]

“My On-X Valves have been great!”

“The On-X valves have been great. I have two of your valves–aortic and mitral. They are not too loud and do not keep me or my wife awake at night. I had surgery to replace my aortic and mitral valves in November of 2006. I researched heart valves on the internet and talked with patients […]

“The On-X Valve was just what I had surmised”

“I opted for an aortic valve repair 8.5 years ago because I was hoping that a new improved mechanical valve would come along before I needed my next operation. The repair worked for a little over 8 years and fortunately, the on-x valve was just what I had surmised and hoped would come to market. […]

“Amazing how far medical technology has come”

I was born with BAV 38 years ago. After researching valve replacements I knew what I wanted before I saw the surgeon(it was never a matter of if but when it would be replaced) and was pleased that he also suggested ON-X. I sometimes hear my AV, but it does not bother me and my […]

Failed tissue valve patient is grateful to receive an On-X heart valve

As elective surgery, I had my first heart valve operation in 1997 to repair my congenital bi-cuspid aortic valve. The initial repair worked well for 3 days, then tore. As a result the surgeons talked me into a pig valve which they said would last from 8 to 16 years. What they neglected to tell […]

“At seven months post-op, I ran my first 5k ever and at 15 months I just completed my first 10k!”

I received my On-X aortic valve on April 5, 2010 at the age of 40 after a few months of declining health. Shortly after birth, it was determined that I had a mitral valve murmur that would likely not cause any issues throughout my life. I had not had my murmur checked for a number […]

International Patient Monitors Own INR

My recovery has gone very well overall; only a slight susceptibility to high blood pressure remaining but I’ve got that under control through medication. I’m very pleased with my choice of valve and I’m aware of the excellent results shown by clinical trials so far. It appears that the On-X has the edge on the […]
