Heart Valve Summit Video #4: “Why Are The New Transcatheter Therapies Only For Inoperable Patients?” Asks Cory

By Adam Pick on November 7, 2011

As we learned last Thursday, the FDA just approved the new SAPIEN transcatheter aortic valve replacement for inoperable patients. This exciting announcement has left many patients and caregivers wondering why the SAPIEN is only for inoperable patients in the United States.

At the recent Heart Valve Summit, I was able to discuss this important topic with Dr. Lars Svensson, MD, one of the leading heart valve surgeons at The Cleveland Clinic. Here are the highlights of Dr. Svensson’s response to Cory’s question, “Why are the new transcatheter therapies only for inoperable patients?”



For the patients and caregivers of our community who are hearing impaired, I have provided a written transcript of this video interview below.

Thanks to Cory for his question. I would also like to extend a special “Thank you!” to Dr. Lars Svensson for his ongoing pursuit of healthy hearts. Doctor Svensson has been intimately involved in the development, clinical use and FDA trials of several technologies that enhance valvular treatment for patients around the world.

P.S. Here is the video transcript:

Adam: “Hi everybody, it’s Adam. We are at the Heart Valve Summit in Chicago, Illinois.  We’re answering your questions that were posted at HeartValveBlog.com.  Very excited to be standing next to Dr. Lars Svensson, MD, who is the director of the Aorta Program and Quality at The Cleveland Clinic in Cleveland, Ohio.  We have a question that came in from Cory, Dr. Svensson, and the question is, “Why is it that all new transcatheter therapies are only for inoperable patients?  Can’t we all benefit from them?”

Dr. Lars Svensson: “That’s a very good question and obviously we’d love to introduce all new technologies, that appear to be working, to all patients, but the FDA has mandated, and rightly so, that we test progressively devices in lower risk populations over time.

So the first study that came out, with the percutaneous valves, the Partner B, as it’s called, was in patients who were inoperable for the traditional surgery, in other words, patients who weren’t being treatment.  So in a sense there was the potential for great benefit in patients who had no other options.  And as far as risk assessment on those patients one can, in a sense, be a bit more forgiving about the risks in that population, because they had no option.

But, as we progressively have looked at lower risk patients, Partner A was a trial that we reported earlier that was in a high risk population.  In the Partner B, the inoperable patients, there, in a sense, the media message was very easy.

We improved survival in these patients by two-thirds, 67% in two years.  Fantastic result, really good, no other option, we did a great job.  In the Partner A, which was the high risk surgical, there we were looking at the comparison with open surgery.  So the headline is not so catchy, but really what it is, is that the percutaneous valves were equivalent to open aortic valve replacement, as far as survival or dying with the operation, at a slightly higher risk of neurological events, particularly stroke and TIA’s.  And the reason why we then cannot open it up, in a sense, to everybody is; first of all, we don’t know what is going to happen in a younger population.

In a younger population you have the demand on the valve, working for a longer time.  And we know, in that population, the results with open surgery are really excellent.  We looked over a seven year period in the 2000’s in our patients, less than the age of 70, having a first time aortic valve replacement at The Cleveland Clinic, and the risk of death was .27%.  Now that wasn’t just a fluke, looking at all of our quality data, obviously, at the clinic, for all patients, who had an aortic valve replacement of an aortic valve plus coronary bypass, for the first 6 months of this year.  We did 398 patients for those operations.  There was only one death, so .25%.  Three patients had strokes, 1% risk of stroke.

So, the new technology has had a higher stroke rate and we want to reduce that before we introduce it to younger patients.  And, I think we are going to do that, the new devices that are becoming available to use together with the percutaneous valves, I think will reduce that risk. So it’s a fine balance, the FDA has to look at the risks of the procedure, the devices versus the safety and the benefits.  So the FDA is in a difficult position in rolling out these two technologies to everybody.”

Adam: “Got it, well Cory, I hope that helped you.  I know it helped me learn more about how eventually we are going to be seeing these new technologies roll out in the new future.  And, I want to acknowledge you, Dr. Svensson, for all the work that you are doing, these new revolutionary technologies, whether it is transcatheter, I know about the recent ValveXchange leaflet replacement system you did in Paraguay.  It’s really just a testament to what you are doing and your pursuit of healthy hearts.  And I know a lot of our patients have come to you and they’ve had great results.  And so I just want to thank you for taking the time to share your expertise with us.”

Dr. Svensson: “My pleasure.  Good talking to you.”

Adam: “Keep on tickin!”

I recently I had a bioprosthetic valve replacement after a failed mitral valve repair at Cleveland Clinic. All of the transcatheter work seems to be centered on the aortic valve. My question is looking to the future, do any of the experts see the transcatheter approach for the mitral valve replacements?

Are you aware of the new medication that could replace coumadin? Is this medication being widely used or is it like the new heart valve replacement procedure being reserved for older patients?

My husband age 91 1/2 who has some idopathic pumonary fibrosis (intisistial disease) has been diagnosed at Univ of Co hospital with severe aortic stenosis (.67 cm). They say he must undergo some risky and expensive tests to determine if he is eleigible for TAVR. Since he refuses open-heart surgery, we hesitat to undergo the tests only to find out that they consider him operable. Are there places we can go that will perform TAVR even if the patient is considered operable, if he is risky and can pass the artery tests? We are anxious for advise. Anne Tolbert for Bert Tolbert
