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.

Dr. Frank J. Veith
Today was day one of the 41st Annual Veith Symposium in New York City. Started by Dr. Frank J. Veith, a pioneer in the field of endovascular approaches to vascular surgery, this five-day event covers the entire field of minimally invasive approaches to clinical situations that just a couple decades ago were the exclusive purview of open surgery.
The whole field of endovascular repair and intervention has grown exponentially since the first endovascular repair of an abdominal aortic aneurysm (EVAR) was performed by Dr. Juan Parodi in 1990, but it took quite some time to be accepted as a standard of care. Today the endovascular approach is the preferred procedure to repair an AAA and this is because of the advances in medical device design and manufacturing and the dedication of physicians to this less invasive non-surgical approach, physicians who will be attending this year’s Veith Symposium.
Today is Veterans Day in the U.S., honoring the soldiers who fought in the country’s wars. Last week was the VIVA 14 meeting, presenting the latest advances and techniques in endovascular repair and therapy of blood vessels.
These two events are actually closely aligned: the development and advances made in vascular surgery, and now endovascular therapies, were pioneered on the battlefield. Continue reading
Dr. Charles Dotter in LIFE Magazine (1964)
Crazy Charlie. An August 1964 LIFE magazine photo spread on Dr. Charles Dotter reinforced that nickname, given to Dotter by the vascular surgeons who knew him and his work at Oregon Health Sciences University in Portland — and who did not like what he was doing. Unblocking arteries in the leg without surgery? From the inside, using catheters? Crazy!
So that was 50 years ago, and to call Dotter a visionary is a vast understatement because this week, radiologists, cardiologists and surgeons have gathered in Las Vegas, not to gamble (although who’s to say…) but to present and hear the latest information, late-breaking trials and reports on vascular interventional therapies at the VIVA 14 meeting and see demonstrations of an array of devices and techniques.

November 4 begins the 14th Annual VIVA meeting in Las Vegas. Yes, that’s “Viva, Las Vegas!”
The whole field of endovascular repair and intervention has grown exponentially since the first VIVA meetings. For example, the first endovascular repair of an abdominal aortic aneurysm was performed by Dr. Juan Parodi in 1990, but it took quite some time to be accepted as a standard of care. Today the endovascular approach is the preferred procedure to repair an AAA and this is because of the advances in medical devices and dedication of physicians to this less invasive non-surgical approach, physicians who will be attending this year’s VIVA meeting.

This week started off with me watching a demonstration of fractional flow reserve (FFR) during multivessel PCI. This very instructive case was transmitted live from Hammersmith Hospital in London and featured Dr. Justin E. Davies showing how to perform FFR and, more importantly, how the use of FFR changed the treatment plan for this patient.
The angiogram had shown three intermediate blockages (LAD, OM, RCA) and, as such, this patient might have been a candidate for CABG instead of PCI. However, when FFR was used to measure whether or not these blockages were ischemic, two were found to be hemodynamically insignificant: it would be safe to defer stenting and treat them medically. The third lesion in the LAD clearly was the cause of the symptoms and stenting would have benefit for the patient. Continue reading
