Online learning has become an increasingly expected and popular component for education of the modern-day adult learner, including the medical provider. In light of recent coronavirus pandemic, there has never been more urgency to establish opportunities for supplemental online learning. Heart University aims to be the ‘go-to online resource’ for e-learning in congenital heart disease and pediatric acquired heart disease. It is a carefully-curated open access library of pedagogical material for all providers of care to children and adults with congenital heart disease or children with acquired heart disease, whether  a trainee or a practicing provder. In this manuscript, we review the aims, development, current offerings and standing, and future goals of Heart University.

Reply to letter “Leveraging e-learning for medical education in low- and middle-income countries”

Cardiology in the Young, June 2020

Justin T. Tretter, Preeti Ramachandran, Bistra Zheleva, Jackie Boucher, Sarah de Loizaga Carney, Jonathan Windram, Andrew N. Redington, Raman Krishna Kumar

“We are particularly pleased and thankful that MA and Vervoort chose to focus their letter on the potential impact which Heart University may play in providing online supplemental education in low- and middle-income countries. While there are many ongoing developments and future aims laid out in our review of Heart University, one for which we are most excited is the e-content aimed for providers of congenital and paediatric acquired heart disease in low- and middle-income countries.”

Telehealth Medicine Use in the Adult Congenital Cardiology Practice - How to Incorporate Telehealth into Your Clinical Practice During These Difficult Times

Congenital Cardiology Today, June 2020

Jonathan D. Windram, BSc (Hons), MBChB, MRCP; Justin T. Tretter, MD; Ami Bhatt, MD, FACC

The COVID-19 pandemic has changed our lives in ways that we did not envisage just over a month ago. At the time of writing, over 170,000 people have lost their lives worldwide and 4.5 billion people are under quarantine to slow the pandemic.1 In addition to the acute burden COVID-19 is placing on our emergency rooms and intensive care units, we are also having to adapt our outpatient clinical practice to delay any non-urgent in-person visits in an attempt to limit exposure to patients and providers. As health care providers we find ourselves rapidly transitioning from the normal clinical visit in person to telephone or telehealth visits when appropriate. How do we do this effectively? What tips and tricks are there to performing a telehealth visit well? And with this increasing comfort and experience with telehealth, are we recognizing there may be an increased role for telehealth which outlives this pandemic?

Are e-learning Webinars the future of medical education? An exploratory study of a disruptive innovation in the COVID-19 era

Cardiology in the Young, December 2020

Colin J. McMahon, Justin T. Tretter, Theresa Faulkner , R. Krishna Kumar, Andrew N. Redington, Jonathan D. Windram

E-learning Webinars represent a disruptive innovation, which promotes deep learning, greater multidisciplinary participation, and greater attendee satisfaction with fewer barriers to participation. Although Webinars will never fully replace conferences, a hybrid approach may reduce the need for conferencing, reduce carbon footprint. and promote a “sustainable academia”.

The Future is Now! A Supplemental Webinar Series to The First International Pediatric Cardio-Oncology Meeting

Progress in Pediatric Cardiology, February 2021

Thomas D.Ryan

Planning for the First International Pediatric Cardio-Oncology Meeting has been underway since early 2019, with the original date in October 2020 delayed due to the COVID-19 pandemic. But patients continue to need care, research carries on, and the ability to learn from our colleagues remains one of the most important tools in our collective ability to advance the field. Through collaboration with Heart University (, a free web-based global education resource and training tool with an emphasis on acquired and congenital heart disease, we are able to provide colleagues around the world with focused sessions similar to those that will be expanded at the in-person meeting. The first such two-hour webinar was presented live online on December 16, 2020, and moving forward similar webinars will be offered approximately every other month for the next year leading up to the in-person meeting in 2022, with all sessions available online afterward for on-demand viewing. Although we are excited to get together with our colleagues in person, why wait until then to share what we know? The future is now!

Webinars reduce the environmental footprint of pediatric cardiology conferences

Cardiology in the Young, March 2021

Brett Duane, Alexandra Lyne, Theresa Faulkner, Jonathan D. Windram, Andrew N. Redington, Sophie Saget, Justin T. Tretter, Colin J. McMahon

While the virtual conference may never completely replace the traditional in-person paediatric cardiology conference, due to networking benefits, the significant theoretical benefits to the environment highlighted in this study, warrants consideration for the virtual conference taking a more common place in sustainable academia.

Medical Education and Training Within Congenital Cardiology: Current Global Status and Future Directions in A Post COVID-19 World

Cardiology in the Young, April 2021

Colin J. McMahon, Justin T. Tretter, Andrew N. Redington, Frances Bu’Lock, Liesl Zühlke, Ruth Heying, Sandra Mattos, R. Krishna Kumar, Jeffrey P. Jacobs, Jonathan D. Windram,

Despite enormous strides in our field with respect to patient care, there has been surprisingly limited dialogue on how to train and educate the next generation of congenital cardiologists. This paper reviews the current status of training and evolving developments in medical education pertinent to congenital cardiology. The adoption of competency-based medical education has been lauded as a robust framework for contemporary medical education over the last two decades. However, inconsistencies in frameworks across different jurisdictions remain, and bridging gaps between competency frameworks and clinical practice has proved challenging.
