FDA Approves Volcano's iFR® Pressure Measurement Modality for Use in Coronary Stent Guidance
Volcano's iFR system measures intracoronary pressures without need for adenosine
The FDA has granted approval to Volcano's proprietary coronary pressure measurement modality, iFR (Instant wave-Free Ratio). iFR represents a significant advance in the field of functional measurement (FM), in which the actual flow pressures inside the coronary artery can be measured and the deficit caused by a coronary blockage or lesion can be accurately assessed....

Can Near-Infrared Imaging Predict Heart Attack Risk?
Infraredx TVC Imaging System
What causes a heart attack? Is it a physical narrowing in the coronary artery, a blockage that can be seen on angiography? Or is it more likely the eruption of a lipid-rich plaque, a so-called vulnerable plaque, that may not look significant in percent stenosis during a standard catheterization? To find an answer, MedStar Heart Institute and Infraredx announced enrollment of the first patient in the Lipid-Rich Plaque (LRP) Study, which will involve 100 centers worldwide and has a target enrollment of 9,000 patients....

Does FAME II Trump COURAGE? FFR: Key to Stents and Angioplasty?
fluoroscopic image
Enrollment for the FAME II trial was stopped after only 2/3 of the planned patients were included. Why? Because the interim data so clearly favor the use of Fractional Flow Reserve (FFR) to guide stenting in stable angina patients that the independent Data Safety Monitoring Board for the trial has concluded that it would be unethical to continue to randomize patients to optimal medical therapy alone....

IVUS Reveals Hidden Heart Attack Culprit In Women.
Angiography vs. IVUS
A heart attack can occur in a coronary artery that looks completely normal on angiography, long considered the "gold standard" of coronary imaging. But newer techniques, such as intravascular ultrasound (IVUS), were able to reveal the cause of the incident: plaque disruption..... (read more)
An IVUS State of Mind
Antonio Colombo, MD
Most cardiologists use an angiogram, a two-dimensional "shadow image" of the coronary arteries, to make treatment decisions. But those who use IVUS and other intravascular technologies see a different picture: a cross-sectional "slice" and a 3-D reconstruction of the blockage. It's what IVUS pioneer Dr. Antonio Columbo calls "an IVUS mentality" and it has forever affected the way he interprets what is going on inside the coronary arteries.... (read more)

Fractional Flow Reserve (FFR)
FloWire® Doppler Guide Wire
A narrowing in an artery may be seen on an angiogram, but is that narrowing causing a problem? One way to determine this is by using a special catheter to measure Fractional Flow Reserve (FFR) which actually quantifies the blood flow and may indicate that an intervention is not necessary.....

Optical Coherence Tomography (OCT): An Overview
OCT
Optical coherence tomography (OCT) is one of the newest intravascular imaging modalities. OCT uses a fine-tuned laser to produce extremely high resolution images that can actually show whether the struts of a stent have been covered or "healed". Like IVUS, there is no radiation involved.

Quote of the Month
“We've known for almost 25 years that visual assessment of angiograms is reproducible and inaccurate. Every angiographer knows you can make a lesion anywhere from 20 to 70%, just by the frame that you pick when you look at an angiogram. The lesson that the interventional community needs to learn is that you have to be really careful about documenting why you are treating moderate severity lesions. And when in doubt, either use IVUS or FFR to make sure that you can prove to people that the lesion is severe enough to be treated.”
