Dr. Charles Dotter in LIFE Magazine (1964)
Who is that mad scientist in the 1964 issue of LIFE magazine? Oh, just the man who invented the concept of angioplasty; in fact he’s the man who actually coined the word “angioplasty!” And he’s the doctor who performed the first angioplasties in the leg, in order to save limbs from amputation without resorting to surgery.
Like many innovators, he had a crazy idea: to open blocked arteries from the inside out. No cutting, suturing, or stitching. Less trauma, lower morbidity, quicker recovery. His name was Charles Dotter and he was a radiologist in Portland, Oregon who, 51 years ago next week, performed an angioplasty on the blocked leg artery of an 82-year-old woman. Continue reading
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.

On October 23-25, 2014 the 3rd Advanced International Masterclass on the Transradial Approach will be held in Chicago and, if you already perform or want to start using the wrist approach to diagnostic or interventional procedures, you need to attend. Where else will you be able to spend two-and-a-half days with the most expert and experienced radial practitioners in the world?
I went to the very successful AimRADIAL course in New York City last fall and witnessed something I hadn’t really seen since the early days of angioplasty: a relatively small meeting (i.e. less than 300) attended by the pioneers of the procedure, cardiologists who have the largest experience in the radial approach, talking among themselves and trading their latest findings and techniques with each other, and sharing this information with the newer generation of physicians in attendance.It felt like an actual community!

It’s been over 35 years since the first angioplasty was performed in Zurich by Dr. Andreas Gruentzig, but it was just yesterday that this minimally invasive procedure arrived in Australia’s Northern Territory.
As reported today by Sky News, Dr. Marcus Ilton, chief cardiologist at Royal Darwin Hospital, performed the first angioplasty and stent implantation ever done in the NT. Continue reading
Symplicity Renal Denervation System
Is the failure of the SYMPLICITY HTN-3 trial to meet its efficacy endpoint the “end of the road” for renal denervation? Will renal denervation now land on the heap of failed technologies? I don’t think so, and Dr. Darrel Francis, the cardiologist who famously predicted that SYMPLICITY HTN-3 would not meet its endpoint, agrees.
In fact Dr. Francis told Angioplasty.Org that it would be a “grave error” if the FDA withheld renal denervation from the American people, based on this news!
OK. Do I have your attention? Continue reading
Slender Club Europe 2014: a new initiative of Slender Club Japan
A criticism from some cardiologists of the transradial approach, in which diagnostic angiography and percutaneous interventions (angioplasty and stents) are performed through the radial artery in the wrist, has been that the radial artery is too small to permit successful navigation of the various sheaths, wires and catheters. Of course, it’s been more than two decades since Dr. Ferdinand Kiemeneij successfully opened a blocked coronary artery via the wrist and today, in many parts of the world, half of all procedures are done this way.
