Running on the Frontline of Cardiovascular Medicine, Science, and Technology

OnWednesday, September 16, 2020, I received the shocking and sad news that James T. Willerson, MD, had passed away. Like many physicians, scientists, and administrators who have been mentored by and worked with Dr. Willerson, I found it difficult to bear the reality that we have lost an outstanding leader, cardiologist, researcher, mentor, collaborator, and friend. Here, in this opinion article, I wish to go through Dr. Willerson’s career and share my own experience of how Dr.Willerson and I came to closely work together and how we becamemore than just collaborators for more than 20 years.
