Dr Yoo is a cardiac radiologist and clinical director of the 3D printing program at the Hospital for Sick Children. He is a professor in the Departments of Medical Imaging and Paediatrics at the University of Toronto. His main clinical and research activities are MR and CT applications in children with cardiovascular disease and fetal echocardiography. He has developed a unique training program for cardiac imaging where both radiology and cardiology fellows collaborate closely together in a harmonious and productive manner. He has introduced 3D printing technology to the program. This technique allows preoperative simulation of the surgical procedures in patients with complex congenital heart disease.

Dr. Valverde was appointed as the Section head of the Cardiac MR program and the Director of the 3D Printing program of the Hospital for Sick Children in 2023. He received his medical degree and residency training in Seville, Spain, and pediatric cardiology fellowship in London, UK. He achieved a postgraduate research degree, MD(Res), at the Biomedical Engineering & Imaging Sciences department of King's College London, UK. His PhD thesis in 2022 was Evaluation of Multimodal Imaging for 3D Printing in Congenital Heart Disease.

Dr Barron is a staff cardiovascular surgeon and head of the Division of Cardiovascular Surgery at the Hospital for Sick Children. His clinical practice focuses on open heart surgery in both pediatric and adult patients with congenital heart disease. His interests include hypoplastic left heart syndrome, congenitally corrected transposition and complex pulmonary atresia.
 

Dr Barron is one of the lead surgical proctors for the HOST program at Sickkids and is involved with curriculum and model development.

Dr Honjo is a staff cardiovascular surgeon at the Hospital for Sick Children. His clinical practice focuses on open heart surgery in neonates and infants, surgical palliation for single ventricle patients, mechanical cardiopulmonary support in the pediatric population, and surgery for patients with adult congenital heart diseases.

​

Dr Honjo is one of the lead surgical proctors for the HOST program at Sickkids and developed the In-House curriculum alongside Dr Yoo and Dr Hussein. He is an integral part of the teaching and validation of the surgical models used in the HOST simulation.

Dr Haller is a staff cardiovascular surgeon at the Hospital for Sick Children. His clinical practice focuses on open heart surgery in both pediatric and adult patients with congenital heart disease. Dr Haller attended the inaugural HOST course in 2015 as a delegate whilst a fellow at Sickkids and now is one of the proctors of the course.

​

In addition to his other research interests, Dr Haller is exploring the use of 3D-printing to gain further insight into complex aortic arch reconstruction. He is collaborating with the 3D printing team to expand the HOST program to minimally invasive congenital cardiac surgery.

Dr Van Arsdell is the Chief of Congenital Cardiovascular Surgery at the Ronald Reagan UCLA Medical Center and former head of the Division of Cardiovascular Surgery at the Hospital for Sick Children. His clinical focus is on neonatal repairs, complex palliations and adult congenital surgery.Along with Dr Yoo, he pioneered the introduction of 3D printing into congenital cardiac surgery with its implementation into hands-on surgical training. Dr Van Arsdell continues to be an integral part of the HOST program, proctoring at the annual sessions.

Dr Hussein is a cardiothoracic surgery resident from the UK with a strong interest in congenital cardiac surgery and medical education. He has recently completed a research fellowship at the Hospital for Sick Children (SickKids), Toronto and was awarded a PhD for his research. His thesis is on creating 3D printed heart models to help train congenital heart surgery residents and fellows in complex pediatric heart procedures. He has a keen interest in surgical simulation and its incorporation into dedicated training programmes.

Brandon graduated from the University of Guelph in 2018 and holds a Bachelor of Science and Bachelor of Engineering. At SickKids, Brandon works as a 3D Printing Manager where he oversees all technical equipment and manages the hospital-wide 3D Printing service. Since working at SickKids, he has become specialized in various medical 3D printing applications including cardiology, orthopaedics, anatomical simulations and surgical tool development.

Dr. Ankavipar Pam Saprungruang is a pediatric cardiologist from Thailand. She received her medical degree from Chulalongkorn university, Bangkok, Thailand in 2011. Pam completed her Pediatric Residency at the Chulalongkorn University followed by her Pediatric Cardiology training at the King Chulalongkorn Memorial Hospital, Bangkok, Thailand. She was working as a pediatric cardiologist at the Cardiac Center, King Chulalongkorn Memorial Hospital prior to coming to Toronto. She completed advanced cardiac imaging fellowship at SickKids in 2020-2021.

Pam joined Dr. Yoo research lab in 2021 for clinical research fellowship in 3D printing heart.

Pascal is a mechanical engineering student at The University of Waterloo and a co-op at SickKids. His research work involves the 3D modelling of heart valves and surgical patching for aortic repair. Pascal also has experience with mechanical design and motor control for surgical robots.

Ms Kim leads the post-processing and quality control aspects of the program. This role is fundamental to the production of the high quality models that are produced. With her educational background of nutritional science and education, she worked as a cytogenetic technologist in Seoul National University Hospital in Korea and SickKids. She is an active advocate of education of congenital heart diseases and surgery using 3D print models. She has volunteered to do tedious detailing process after the models are printed. With her exceptionally versatile and fine hands, she makes the aesthetic touches on the models. Her pioneering vision and support has been instrumental to the development of the 3D-printed heart program. 

Dr. Tanaka is an anesthesiology resident at Stanford Health Care with a strong interest in congenital cardiac anesthesia and anesthesia for adult congenital heart disease. He received his medical degree from the University of Toronto in 2024. During medical school at the University of Toronto, Dustin became a crucial part of the Hands-On Surgical Training (HOST) team

Dustin also completed multiple clinical rotations with the Labatt Family Heart Centre at the Hospital for Sick Children (SickKids) in pediatric cardiology, congenital heart surgery, and congenital cardiac anesthesia. These formative experiences have inspired him to pursue congenital cardiac anesthesia and simulation-based medical education.
