A Stent By Any Other Name

Stent and RoseForgive the perverse Shakespearean pun in the title but, as the Bard wrote: “What’s in a name? That which we call a rose by any other name would smell as sweet.” My topic is pretty much the polar opposite of roses, but the whole concept of labels and what we call things has become increasingly important. It’s one that I touched on in my post over last weekend about the impending CMS audits of stent procedures: namely, that the “official” terms used to describe treatment of a blocked artery are flawed when it comes to proper use of the English language.

The official “Appropriate Use Guidelines” place stent and angioplasty procedures into three categories: Appropriate, Uncertain and Inappropriate. Any patient, potential patient or, for that matter, anyone not steeped in the minutiae of interventional cardiology, would look at those terms and assume that any doctor putting a metal coil into someone’s heart when the procedure was labeled “uncertain” or “inappropriate” should be fined or fired or both.

Stents, Angioplasty and PCI: The Uncertainty Principle (MEDICARE Style)

Is This Stent Necessary?The question of the day, regarding whether or not to stent a coronary artery, is now being brought to the forefront by the U.S. government in the form of a Medicare “Demonstration Project”. And by “brought to the forefront”, I mean MONEY! — as in “we won’t pay you if we determine that the stent procedure was inappropriate.”

The bottom line is that, on November 15, CMS announced “New Demonstrations to Help Curb Improper Medicare, Medicaid Payments“. These so-called “demonstrations” will occur in 11 states where claims “historically result in high rates of improper payments”: Florida, California, Michigan, Texas, New York, Louisiana, Illinois, Pennsylvania, Ohio, North Carolina and Missouri.

Women’s Heart Disease and Intravascular Ultrasound (IVUS)

I’ve written before about the use of IVUS in stent and angioplasty procedures in women, most recently in October about a study done at NYU Medical Center. My article, “Intravascular Ultrasound (IVUS) Imaging Reveals Hidden Heart Attack Culprit In Women“, showed how intravascular imaging could detect a type of coronary disease not seen on angiography.

Now a similar tale has been broadcast by CBS affiliate WGCL-TV in Atlanta about how a type of coronary narrowing more typical in women may not be seen on a standard angiogram because it’s evenly distributed along the arterial wall or channel and doesn’t appear as a “spike” or sudden narrowing — yet it may be restricting the flow of blood to the heart just the same. Once again — angiography alone is not enough to accurately diagnose coronary artery disease and guide its treatment. Continue reading

Stent as Concertina

A "Stent Concertina"Call it an accordian, a concertina or a “squeezebox”…but don’t call it a stent. Because one thing that is not music to your ears is a coronary stent that you have carefully placed to relieve your patient’s symptoms — and which then gets shorter or longer when you push or pull another catheter, balloon or wire through it.

This is an issue that was first raised a little over a month ago and it has been the subject of a number of news articles. It’s been dubbed “the concertina effect” but its scientific name is “longitudinal stent compression” or “longitudinal stent distortion” and it’s of concern because once a stent has been correctly sized and placed in just the right position to keep a blockage open…well, you don’t want it moving or changing shape.

iFR: A New Way to Judge Stents and Angioplasty for Coronary Blockages?

angiographic image of stenosisFor several years now, I’ve been advocating for expanded use of functional measurement, otherwise known as Fractional Flow Reserve (FFR), as a way of determining whether or not a blocked artery is actually causing ischemia. A new measurement, made possible by recent advances in computer technology, called iFR (instant wave-Free Ratio™) may provide the momentum that pushes this concept into mainstream cardiology. Continue reading

How Do We Know That TCT 2011 is Done?

Angioplasty.Org image of the end of the TCT 2011While a number of the 12,000 attendees started leaving and catching planes to their home bases all over the world yesterday, some to Florida for the beginning of yet another major heart meeting, the AHA, and some who will be off next week to the Veith Symposium in New York, the real evidence that TCT is over for the year is this view of the Exhibit Area, taken moments ago: rugs rolled up, fork lifts rolling forward, hi-tech exhibits slid into wooden framed crates….

Next year, TCT will be held in Miami, Florida on October 22-26, 2012 and the following year will be back in San Francisco.

SRO Times 5 for Transradial Symposium at TCT2011

Transradial symposium at TCT2011

Transradial Symposium at TCT2011

Today I saw hard statistical evidence that the transradial approach is growing exponentially in the U.S. This photo, taken this afternoon, during the half-day transradial symposium at TCT2011 says it all. 800 cardiologists were packed into room 104 of the Moscone Center in San Francisco to hear 5 hours of presentations and discussions on the transradial approach to diagnostic angiography, angioplasty and stent placement.

As transradial pioneer Dr. Tejas Patel said to me after the session, inadvertently doing a San Francisco shout-out, “It was a Full House!”

It was more than a full house, with doctors lined up against the back and side walls and, of course, people leaving and more coming in. Most likely, well over 1,000 cardiologists attended all or part of this session. Continue reading
