A local research team from Gosford and John Hunter hospitals has collaborated on an important study with the potential to improve patient experiences during angiograms and stent procedures. This innovative research makes heart procedures safer, quicker, and more comfortable—especially for women. Read on to learn how our Central Heart team is working to transform patient care.
The EAGER randomised controlled trial
The EAGER study (Enhancing Guidewire Efficacy for Transradial Access), published in the Circulation: Cardiovascular Interventions, that included more than 330 patients was led by Central Heart’s Dr. Adam Bland (first author) and Associate Professor Tom Ford (principal investigator) who are both passionate about improving patient care and outcomes. Their research is helping to transform the way blocked arteries are treated, thanks to a new guidewire called the Baby J. A guidewire is a medical device used to guide the catheter into place during heart procedures. The purpose of a guidewire is to gain access to the blood vessels using a minimally invasive technique.
A big change in heart procedures
For decades, heart procedures were performed through an artery in the groin—known as the transfemoral approach— but this carried higher risks like bleeding and longer recovery times. Modern research shows that accessing the heart through the wrist is safer, more comfortable, and speeds recovery. As a result, international guidelines now dictate that the radial approach should be used whenever possible. However, the traditional guidewires used in these procedures weren’t designed for the smaller arteries in the wrist. The diameter of a typical female radial artery is under 2mm.
This challenge inspired Dr. Bland and A/Prof Ford to design the EAGER study and test the Baby J guidewire in a groundbreaking randomised controlled trial. The Baby J guidewire is a smaller, more flexible tool specifically designed for transradial procedures. They recently discussed the study with colleagues and friends at Gosford Hospital in a feature for NBN News.
Why the Baby J guidewire is a crucial innovation
The Baby J guidewire has proven to advance cardiac care significantly. The EAGER study’s findings demonstrate its impressive benefits:
- Higher success rates: The Baby J successfully navigated to the heart in 96% of cases, compared to 84% with the traditional wire.
- Better outcomes for women: Women, who often face more complications with traditional wires, experienced a 35% higher success rate with the Baby J.
- Faster procedures: The Baby J reduced procedure time and cut down on radiation exposure for both patients and medical staff.
- More comfortable experience: Patients reported smoother and less painful procedures.
Patient story: Gail
For patients like Gail of Wyongah, the difference was clear. She had a complex stent procedure through her wrist to treat a severely calcified blocked artery causing angina. Using a specialised tool (a coronary drill) and the Baby J guidewire, doctors Ford and Spina were able to complete the procedure smoothly. Gail was amazed at how quick and painless it was.
“As soon as the procedure started, it felt like it was over,” she said. “I didn’t feel a thing. Afterwards, I noticed a little pain in my hand for a couple of days, but that was it. It was no big deal whatsoever.”
Gail’s story highlights the real-world impact of this innovation, made possible by the teamwork and dedication of the staff at Gosford and John Hunter Hospitals. This study is a testament to what can be achieved through collaboration, even in a semi-regional setting with less resources.
“It was a true team effort—nurses, radiographers, technicians, and physicians all played a crucial role, and I pay tribute to their hard work and commitment,” said A/Prof Ford.
“Innovation thrives when good people come together.”

The vision behind the EAGER study
For A/Prof Ford, the motivation behind the EAGER study was simple: improving patient outcomes.
“The guidewires we’ve been using for years were designed for larger arteries in the groin, not the smaller arteries in the wrist,” said A/Prof Ford. “The Baby J wire changes that, especially for women, who are more prone to complications like bleeding. This wire improves success rates, reduces procedure times, and makes the whole experience safer and more comfortable for our patients.”
Dr. Adam Bland, the study’s first author, sees the Baby J as a catalyst for change in cardiac care worldwide.
“Our work has already been presented at the European Society of Cardiology conference in London, the largest cardiology event in the world, and published in Circulation: Cardiovascular Interventions, a leading journal [from the American Heart Association],” Dr. Bland said.
“I’m proud of what we’ve achieved here on the Central Coast and in the Hunter. This study is proof that local innovation can have global impact.”
Leading the way for future care
Thanks to the leadership of Dr. Bland and A/Prof Ford, the Baby J guidewire is now becoming standard practice at Gosford and John Hunter hospitals. Their research is already inspiring changes in how heart procedures are performed, both in Australia and around the world.
“This technology represents a small change that has a big impact,” Dr. Bland said. “It’s about making procedures safer and more efficient, while also improving the experience for patients. We’re excited to see how these innovations continue to shape the future of cardiac care.”
A/Prof Ford credits his colleagues at Gosford Hospital and John Hunter Hospital, and patients at Central Heart for their contributions and trust. “The results of the EAGER study wouldn’t exist without the courage of our patients and the dedication of our team,” said A/Prof Ford. “This is just the beginning of what we can achieve together.”
