Barbara Walters Interviews Her Aortic Valve

Voiceover speaks in the background...
"It has worked for years, tirelessly opening and closing. Now, saddled with the challenges of age, Barbara Walters spends a few comfortable moments interviewing her critically narrowed aortic valve, for what comes next..."
"So, A.V., this must be very hard for you, being replaced and all."

Tears welling...

"Yes.... yes, it is. I mean all these years opening and closing, opening and closing and just because I get a little stiff, this is the thanks I get. The prospect of some cow or pig thing doing what I've been doing for years.... It's devastating...."

"What will you do next?"

"I mean, that's just it! Don't you see? I'll just sent packing to some cold, silver kidney basin to the basement, only to be palpated and sampled, frozen and sectioned, while they get the benefit of anti-platelet agents. Then, God who knows what!?.... But I'll miss you Barbara..."

"Oh, A.V.!"

(A pause... Barabara herself grabs a Kleenex...)

"Seriously, thanks to you there'll be no more gradient, no more being pushed around. But I feel good knowing one thing..."

(Another pause)

"What's that, A.V.?"

(Blushing and turning away...)

"I know who will be your first guest on The View when you return in September!"

Prosthetic Aortic Valve? There's an App For That!

Meet iAorticValve produced by iMobileHealthCare, available now for upload to your iPhone.

In an era where the medical device industry is increasingly concerned about health care reform, innovation, and the implications for providing their products to patients, it's nice to know there are helpful companies sprouting up that can place company literature about mechanical, biologic, or percutaneous prosthetic aortic valves, both approved and experimental, on your iPhone free of charge. Further, if you want to go ahead and calculate your own STS (Society of Thoracic Surgery) Risk Calculator for placement of a heart valve, heck, you can do that also.

Do not, however, look for objective criticism of the various valve types since most device literature there fails to include warnings, containdications, or adverse events about the devices. Further, references were not hyperlinked, making the utility of the quickly reviewing the references challenging for the casual user. Maybe more information is provided if you're a patient that registers for the $39.99 (doctors pay $59.99) annual access fee to become part of the "network," but I regret that I failed to cough up the change when I realized I could just search Google instead on my iPhone for the same information.

However, I did register as a "patient" as a free trial to look around, and saw some nicely-produced industry videos from YouTube for my consumption, information on some nice doctors with an interest in experimental percutaneous valve placements and thoracic surgery along with information on which insurers those doctors accept.

But a word of caution is also in order. The images and content I found on the iPhone app appear to be those also displayed on the manufacturers' websites and from doctor's available online webpages. Whether or not these doctors are aware that this information exists there is uncertain. I did a little investigative reporting and discovered that at least one of the doctors on the company website did not personally register his information nor grant permission for its use there. In short, then, the iMobileHealthCare team appears to have aggregated information from various web sources with a heavy bias toward percutaneous aortic valve implantation. I could find no disclaimer to this effect on their site.

US FDA regulations that clearly state that marketing experimental devices before they are properly labeled is strictly prohibited. But does that marketing scheme pertain to other companies that don't make those devices? I don't know. It is interesting that this app promotes doctors who are investigating some of the percutenous aotic valve devices to patients eager to "learn more." I'll let you decide if that sounds like marketing.

But alas, it's a new iPhone frontier and the information contained on the device is out there in other locations on the web. Feel free upload the 5+ megabyte app on your iPhone for "free" and look around at the pretty pictures and see the link under "Resources" to PubMed's home page or the blog with a few entries. While there are a few bugs in the software, it's interesting to see where things are going in mobile health care information age for patients and doctors.

It's also interesting to see the challenges industry will have going forward trying to comply with FDA marketing regulations.

Robin Williams Discusses his Aortic Valve Replacement

He's an exerpt from a candid video where Robin Williams discusses his rationale for choosing the type of valve replacement he received:
"... here are your choices:
  • pig valve, which is great, you can find truffles,
  • mechanical valve, which clicks and you know, weird, (eds note: that also requires chronic anticoagulation)
  • and bovine - great, 'I'll go bovine, Bob, for 20!'"
The video provides a very real (and, yes, humorous) glimpse into the emotional and physical impact of aortic valve surgery as only Robin Williams can portray.
