Interventional Cardiologists at Presbyterian Hospital of Dallas Perform Peripheral Vascular Cases for International Audience

DALLAS — Presbyterian Hospital of Dallas is one of only a handful of medical centers in the United States — and the only Texas facility — to broadcast live interventional cases to the prestigious Vascular InterVentional Advances conference, held this week in Las Vegas, Nev.

The VIVA conference will educate over 1,000 physicians and medical personnel on the latest advances in the treatment of peripheral vascular disease (PVD), a looming health crisis as the U.S. population ages and more Americans battle obesity.

Drs. Tony Das and James Park, interventional cardiologists on the medical staff at Presbyterian Hospital of Dallas, will perform cases designed to teach cardiologists, vascular surgeons and radiologists around the country about the latest advances in clinical care for PVD. The cases will be performed in the cardiac catheterization lab at Presbyterian Hospital of Dallas and transmitted in high-definition to the conference in Las Vegas, where cardiac experts from around the world will be assembled.

“With the prevalence of diabetes and obesity among an already aging population, the challenges facing those involved in the diagnosis and treatment of peripheral vascular disease are overwhelming,” Das said. “It’s a problem that will increasingly challenge medical experts around the country in coming years.”

Other sites for live cases include The Cleveland Clinic and the University of California Davis Medical Center.

Das and his colleagues will demonstrate complex vascular procedures to open and stent arteries supplying the kidneys, focusing part of their session on the increase in renal artery disease in the United States. Other cases will focus on techniques to open complex blockages of the femoral and tibial arteries, which supply blood to the lower limbs.

“What makes this conference so important is that it’s about teaching, not just demonstrating,” Park said. “The idea is to share our knowledge with others, so we can begin to address these health problems in an effective way in the communities and hospitals where these physicians practice.”

PVD is a common condition affecting more than 10 million adults in the United States. The condition is a disease of blood vessels outside the heart and brain characterized by a narrowing of vessels that carry blood to the legs, arms, stomach and kidneys.

Cases at Presbyterian will also demonstrate advanced ways to clear vascular blockages in leg arteries, that, if untreated, can lead to tissue loss and ultimately limb loss. A new technique to treat these blockages involves using a tiny crown coated with diamond chips that rapidly spins at high speeds and sands away plaque inside leg arteries — while preserving the healthy tissue of the arterial wall. Orbital rotational force causes the tip of the device to expand inside the artery as it slowly sands away plaque and opens the artery to restore proper blood flow.

“These treatments are among our best tools to treat peripheral vascular disease and restore blood flow to the legs and feet,” said Dr. Kenneth Saland, an interventional cardiologist on the medical staff at Presbyterian Hospital of Dallas and part of the team that will present cases to the VIVA conference. “Advanced treatments like these are keys to effective limb salvage.”

“The VIVA conference participation is just another example of the commitment by physicians on the hospital's medical staff and Presbyterian Hospital of Dallas to provide comprehensive, leading-edge quality heart and vascular education and care to the medical community and patients we serve both locally and globally,” said Jon Gardner, Presbyterian's director of the heart and vascular service line.

Procedures also will include demonstrations of techniques to treat restenois, which is a re-narrowing or additional blockage buildup inside artery walls that have been previously treated. The VIVA conference will host experts in the various specialties that treat vascular disease, including vascular surgery, interventional cardiology, vascular medicine, interventional radiology, neuroradiology, neurosurgery and cardiothoracic surgery.

The conference will feature “laptop learning,” a computerized system that integrates a variety of media into a customizable learning program. Each attendee of the conference can communicate privately with select faculty, either experts at the conference or presenting physicians such as Das and Park. The conference will also feature “chalk talks” between conference attendees and faculty.

The Research and Education Institute for Texas Health Resources (TREI) provided technical support and assistance in the preparation and production of this event through the Presbyterian Institute for Minimally Invasive Technology (PIMIT). TREI conducts research that contributes to the prevention, diagnosis and treatment of disease, and offers continuing medical education to physicians and other health care professionals. Through PIMIT, TREI conducts clinical outcomes research on the efficacy and cost-effectiveness of minimally invasive procedures, and trains physicians and other health care professionals in the use of minimally invasive technologies.
