On September 22-23, 2016, the 5th Advanced International Masterclass on the Transradial Approach will be held in Budapest, Hungary. And this year, AimRADIAL will be preceded on September 21 by a one-day comprehensive workshop covering all aspects of Fractional Flow Reserve (FFR) from the basic principles and set-up in the cath lab, to the differences between FFR, iFR, and CFR, a comprehensive review of the clinical study data so far, and finally a look at future modalities, like FFR-CT (although the title of that talk by Dr. Nick Curzen is “FFR-CT: the future is now“).

Consumer Reports regularly publishes health information to aid the consumer/patient in making decisions. And that’s a good thing. But also important is having the most current information, which their January 27, 2015 article, titled “The surprising dangers of CT scans and X-rays,” does not.

Rumors and theories about an acquisition of Volcano Corporation (NASDAQ: VOLC) had been circulating for quite some time: months, years even. The company seemed an obvious choice: it has an advanced intravascular ultrasound (IVUS) technology that leads the market, with Boston Scientific coming in second; it has a fractional flow reserve (FFR) wire that splits the market with St. Jude Medical; and recently Volcano gained FDA approval for its Instant Wave-Free Ratio (iFR) physiologic measurement product, a faster, cheaper potential alternative to FFR.

Former President George W. Bush received an angioplasty and stent this morning at Texas Health Presbyterian Hospital Dallas. The stent was recommended by Bush’s doctors to open a blockage in one of his coronary arteries, found yesterday during what was described by Bush spokesman Freddy Ford as his annual physical exam at the Cooper Clinic in Dallas.
