What if a surgeon could hold your child’s heart before ever stepping into the operating room? In this episode, we sit down with Dr. Tristan Ramcharan — Consultant Pediatric and Sports Cardiologist at Birmingham Children’s Hospital — to explore how 3D printing is quietly revolutionizing one of medicine’s most emotionally and technically demanding fields. From surgical planning to bedside family conversations, Dr. Ramcharan’s program is proof that the future of pediatric cardiology isn’t coming — it’s already here.

Episode Outline:

  • How Birmingham Children’s Hospital built its 3D cardiac printing program with Aston University
  • The three core use cases: surgical planning, medical education, and family communication
  • Why 3D-printed models are replacing irreplaceable post-mortem specimens
  • The BBC feature documenting a family receiving a 3D model of their child’s heart
  • The NHS funding gap and how a £150,000 charity grant holds an entire program together
  • The generational divide between 2D-trained clinicians and digital-native trainees
  • Where 3D printing goes next — neurosurgery, maxillofacial, and hospital-wide expansion

Dr. Tristan Ramcharan is a Consultant Paediatric and Sports Cardiologist based in Birmingham, UK, working at Birmingham Children’s Hospital. He specializes in the management of congenital and acquired heart conditions in children and young athletes, with expertise in advanced cardiac imaging, including stress echocardiography and cardiac CT.

He holds an MSc in Sports Cardiology with Distinction from St. George’s, University of London, and has expertise in the young athlete’s heart as well as patients with exercise-induced symptoms and cardiac rehabilitation. He looks after young athletes from around the UK and also provides a second opinion and advice service for national and international colleagues looking after young athletes with heart conditions or cardiac patients with professional athletic ambitions.

Dr. Ramcharan is an active researcher with international presentations and peer-reviewed publications in pediatric cardiology and sports cardiology, recently co-authoring the BSE Echocardiography in the cardiac assessment of young athletes guideline.

He is a member of the Football Association’s Sport Cardiology Expert panel and is also an honorary senior lecturer in Sport Cardiology and module lead for the MSc in Sport Cardiology at City St. George’s, University of London.

Episode Timeline

0:00  —  Cold Open & Guest Intro

Dr. Ramcharan introduces himself — Consultant Paediatric & Sports Cardiologist at Birmingham Children’s Hospital, covering congenital heart disease and young athlete care.

1:10  —  The 3D Printing Program

Three years of 3D printing at BCH in collaboration with Aston University. Three core use cases introduced: surgical planning, medical training, and family education.

1:55  —  Surgical Planning

How 3D-printed heart models help surgeons map complex congenital anatomy — locating holes, understanding structural relationships — before ever entering the operating room.

2:45  —  Medical Education

Replacing finite, irreplaceable post-mortem morphology specimens with printable, repeatable 3D models. Trainees can handle and learn without degrading a 30–40-year-old specimen.

3:15  —  Family Communication & BBC Feature

The most impactful use case: helping families understand why a healthy-looking child has a serious heart condition — or why surgery simply isn’t possible. BBC documentary case study discussed.

5:12  —  The Role of Imaging

From M-mode black-and-white echocardiography to CT, MRI, and 3D reconstruction. How the imaging evolution made 3D printing possible and what it means for clinical understanding.

6:54  —  2D vs. 3D: Where Are We Heading?

The generational divide between physicians trained on 2D datasets and newer trainees fluent in both. The honest answer: somewhere in between, for the foreseeable future.

8:23  —  Generational Change in Medicine

Medical students who own their own 3D printers. Digital natives entering the field. What will training look like in 10 years — and who decides?

9:51  —  Conference Takeaways — Materialized

Discovering how other specialties use 3D segmentation — neurosurgery, maxillofacial — and bringing those ideas back to BCH. The spark for expanding the program hospital-wide.

11:34  —  NHS Funding & Reimbursement

The hard reality: 3D printing is not yet recognized as standard of care within the NHS. A £150,000 charity grant from Birmingham Children’s Hospital Charity funds the entire program.

12:51  —  Charity Funding & What’s Next

Staying local with charity support for now. Future ambition: cross-centre collaboration across the UK as the technology gains clinical acceptance.

13:28  —  Message to the Next Generation

Why medicine — and particularly paediatric cardiology — remains one of the most rewarding careers imaginable. The emotional weight and the profound gratitude of families.

14:44  —  Closing

Host thanks Dr. Ramcharan, acknowledges the difficult conversations paediatricians carry, and shares the donation link for Birmingham Children’s Hospital Charity.
