ACC | April 30, 2012

One of the most interesting educational exhibits at the recent American College of Cardiology (ACC) 2012 Scientific Session was "The Heart of Innovation" display on the show floor. The ACC in collaboration with marquee sponsor Philips Healthcare and several other industry leaders created this non-accredited, hands-on education experience. The exhibit explored the evolution of the standard-of-care for heart disease and heart failure caused by valvular disease. It looked at these issues through the lenses of personalized medicine, techno-biology, minimally invasive procedures and physician-patient engagement. The exhibit included technology from the past, present and future of healthcare. To incorporate a historical view, the entrance to the display included the ACC's special collection of historic artifacts encompassing medical books, stethoscopes and device technology dating back hundreds of years, including a stethoscope from 1535. This historical perspective was juxtaposed with a modern attendee experience that included the option to explore the entire exhibit with a specially provided iPad tour. The centerpiece was a mockup of a hybrid OR. It included a Corindus CorPath robotic cath lab intervention guidance system. Other partners included Maquet, showing a portable heart-lung machine the size of a small suitcase and the CFI Medical Solutions ZeroGravity radiation protection system. What made the hybrid OR particularly unique was that it was situated across from the Minimally Invasive Gallery, which featured many of the innovations that are driving procedures performed in the hybrid OR. The gallery encompassed solutions from Medtronic and Edwards Lifesciences, including Edward's breakthrough Sapien transcatheter heart valve. The display discussed current treatments and what the future technologies will likely be from the standard-of-care in the future.

New evidence shows that with appropriate preparation, angioplasty can be safely and effectively performed at community hospitals without on-site cardiac surgery units. This was according to data presented from the CPORT-E trial during the American College of Cardiology (ACC) 2012 Annual Scientific Session. The study is the first randomized controlled trial to investigate elective cath lab angioplasty (or percutaneous coronary intervention, which includes stenting and balloon angioplasty) in community hospitals in the United States.

Results showed no difference in death rates among patients undergoing elective angioplasty at facilities with and without on-site cardiac surgery units. There were also no significant differences in rates of complications such as bleeding, renal failure and stroke. "The study shows that under certain circumstances, non-primary angioplasty can be performed safely and effectively at hospitals without on-site cardiac surgery," said Thomas Aversano, M.D., associate professor of cardiology at Johns Hopkins University and the study's lead investigator. Until a recent guideline change by the American College of Cardiology and the American Heart Association, community hospitals without cardiac surgery units performed only emergency angioplasties. Patients needing elective angioplasty were transferred to facilities with on-site cardiac surgery units. "The study supports and reinforces the [new] guidelines," said Aversano, adding that the findings can help hospitals and healthcare planners more efficiently allocate financial and human resources. The ability for community hospitals to offer elective angioplasty benefits patients, Aversano said. Other studies have shown that patients are often reluctant to transfer to a hospital that may be farther away or more expensive than their community hospital. "It's not just a question of patient convenience — it's also a question of access," he said.

Radial Access | April 28, 2011

In the largest randomized trial to compare radial access and femoral access for coronary angiography and intervention, researchers found radial access reduced rates of vascular complications, according to research presented at the American College of Cardiology (ACC) 2011 Scientific Session in New Orleans. The trial also found that radial access did not reduce the primary outcome measure of death, heart attack, stroke and non-CABG-related major bleeding compared to femoral access in the overall study population. The data showed these outcomes were equal for both femoral and radial access procedures.

"Interventional cardiologists can feel reassured both radial and femoral approaches are safe and effective," said Sanjit Jolly, M.D., M.Sc., assistant professor of medicine at McMaster University in Hamilton, Ontario, Canada. Radial access did lead to reductions in the primary outcome measure in patients who underwent the procedure at hospitals that conducted a high volume of radial procedures. For centers that were less experienced with radial access, Jolly said it was clear there is a learning curve, and operators got better and faster with radial procedures with more experience. "The take-home message is practice makes perfect," he said. Jolly explained the high-volume centers using radial access performed very well, but it was clear from the study operators need a lot of radial cases to increase performance.

Radial Access | March 22, 2011

St. Joseph's Hospital of Atlanta created a radial access recover room that replaces beds and the sterile institutional hospital look with a more patient-friendly design. Transradial access is slowly gaining ground in the United States as more physicians make the switch due to greatly reduced bleeding complications, increased patient comfort and earlier ambulation. St. Joseph's Hospital of Atlanta is a big supporter of radial access and has taken the concept a step further by creating the first transradial recovery lounge in the country.

"I really see this as the future of cardiac care, not just as an alternative access route for percutaneous coronary intervention, but also to improve the patient experience and reduce their hospital stay," said Jack P. Chen, M.D., FACC, FSCAI, FCCP, director of cardiac research, St. Joseph's Translational Research Institute, Saint Joseph's Heart and Vascular Institute, Atlanta. A trend in medical facility design over the past 15 years has moved away from the sterile, institutional look of traditional hospitals. Instead, more inviting, warm and friendly looking facilities are being built to make patients feel more comfortable. This concept is now being applied to the cath lab recovery room. Use of radial access allows for immediate ambulation, and thus a major revision to recovery room design, replacing beds with couches and recliner chairs. St. Joseph's Hospital is the first in the United States to build a cafe-like lounge exclusively for radial access patients.

Chen took the idea from Ferdinand Kiemeneij, M.D., department of interventional cardiology, Onze Lieve Vrouwe Gasthuis, Amsterdam, The Netherlands. He created the first radial access recovery room in Europe after getting the idea from a KLM airline lounge. "The idea is to build a cafe-type atmosphere to reduce the anxiety associated with invasive heart procedures," Chen said. "When I first approached the hospital administration with this idea, they required a bit of convincing. However, after seeing the patient satisfaction and alleviation of complications stemming from this technique, all were in agreement that this concept may well be the wave of the future."

He said the hospital embraces the radial access approach as a new frontier in interventional cardiology and agreed to build the new recovery area. "To me, this rounded out the picture of a more patient-friendly cardiology program for what is essentially a minimally invasive catheterization/interventional procedure," Chen said. Patients sit in the lounge chairs for 30 minutes to an hour, only to recover from the sedation. The patients are then allowed to ambulate in their street clothes. They can walk around or sip a cappuccino, Chen said.

The recovery room has comfortable reclining chairs instead of beds and there are couches and coffee tables topped with magazines and newspapers. The recliners have attached swing-up tabletops where patients can put a laptop computer and check their e-mail or surf the Internet. The idea is to eliminate the sterile, institutional appearance of most recovery rooms and to relax the patient with a more inviting atmosphere. â??We are trying to take the hospital out of the equation," Chen said. "Patients are much more at ease than they would be in a typical hospital setting. To allow them to put their street clothes on really reduces the anxiety they have." The lounge was showcased and visited by many cardiologists from around the country during the American College of Cardiology (ACC) Annual Scientific Sessions in March 2010, which were held in Atlanta.
