Fourth Year of Advanced Training
Pediatric Advanced Cardiac Imaging Fellowship
Children’s Hospital Colorado, in conjunction with the University of Colorado School of Medicine, is pleased to offer a funded position for a fourth year of advanced training in Pediatric Advanced Cardiac Imaging. We are looking for well-qualified candidates who have completed a fellowship in pediatric cardiology at an ACGME-accredited program, and will be board eligible by the start of the 4th year.
The Cardiac Imaging and Fetal Cardiology group at Children's Hospital Colorado is a rapidly growing and busy group. We have 12 pediatric cardiologists with advanced training in non-invasive imaging, including subspecialists in fetal echocardiography, cardiac MRI and CT, 3D echocardiography, and speckle tracking echocardiography, with that number likely to rapidly grow.
Our lab performs and interprets over 23,000 studies per year, utilizing a state-of-the-art digital PACS system as well as telehealth options, serving a large 7 state region. Our hospital consistently has one of the highest volumes in cardiovascular surgery, Norwood procedures, heart transplants, and cardiac catheterization & electrophysiology procedures in the United States, along with robust ventricular assist device and ECMO programs, ensuring exposure to a wide range of cardiac pathology and therapies.
We have trained 1-2 4th year fellows in advanced cardiac imaging every year for over a decade. While all fellows will gain extensive experience in echocardiography and are expected to complete the year as experts in the performance and interpretation of transthoracic & transesophageal echocardiograms, our 4th year fellowship is customizable to the career interests of the fellow, and we offer additional focus in areas such as fetal echocardiography, cardiac MRI & CT, 3D echocardiography and speckle tracking echocardiography. Our 4th year fellows will also gain experience in imaging research, with the expectation to complete a first-authored manuscript on a project of their choosing.
Our institution uses the Pediatric Advanced Cardiac Imaging match listed on the San Francisco Match site, and all applications and necessary materials must be completed through this process. If you are not a USA citizen, include a copy of your ECFMG, and bear in mind that you would need to acquire a J1 visa if selected as a candidate for our program. Incomplete or late applications will not be considered. It is your responsibility to ensure all required information has been received.
The timetable for the application process is detailed on the SF Match site, and the process will start on July 1st. All applications should be submitted by September 17th.

Why did you decide to pursue pediatric cardiology?
I was drawn to pediatric cardiology because it combines complex anatomy and physiology with the ability to care for patients and families over time. During fellowship, I was drawn to imaging and the role it plays in shaping clinical and surgical decision-making. Pediatric cardiology felt like the perfect balance of intellectual challenge, collaboration, and meaningful long-term patient relationships.
What made you decide to train at Children's Hospital Colorado for your advanced fellowship?
Colorado stood out to me because of the combination of strong clinical training, innovation in imaging, and supportive, collaborative nature. I was especially excited about the strength of the 3D echocardiography and fetal programs. It felt like a place where I could grow as an imager, researcher, and educator.
What are your hobbies and what do you like to do in your spare time?
Outside of medicine, I love being creative and spending time outdoors. I have a background in art and enjoy painting. I also love hiking, running, long walks with my dog, but also love loafing on the couch with a good book. My husband and I love trying new restaurants, cooking, and spending time with family and friends.
Pediatric Cardiac Intensive Care Fellowship
The overall improving results in the management of pediatric and congenital cardiac disease have been recognized as the result of an intense multi and trans-disciplinary effort. This important interaction between pediatric and adult cardiologists, surgeons, intensivists, anesthetists, pharmacists, research staff, nurses, respiratory therapists, perfusion technicians, nutritionists, psychologists, physiotherapists and other specialized staff optimizes conditions to provide an outstanding quality of care to our patients and their families. The advantages of such collaboration allied to the need for highly reliable clinical practices widely justify a specific training in the arena of cardiac intensive care allowing fellows to fully develop comprehensive skills in both cardiology and intensive care, whilst learning how to integrate the team, patients and their families into their activity.
Children’s Hospital Colorado provides a comprehensive training program for pediatric cardiac intensive care 4th year fellows (CICU fellows) and the academic opportunities are tailored to suit background, needs and interests of each candidate. There is a dedicated 22 bed pediatric cardiac intensive care unit hosting categorical fellows of pediatric cardiology, neonatology, general pediatric intensive care and anesthesia, and Advanced Practitioners (Physician Assistants and Nurse Practitioners), who work in collaboration with or under the supervision of the 4th year CICU fellow.
The Senior Fellowship curriculum is specifically designed for each individual fellow in order to adequately prepare the trainee to care for patients with critical congenital heart disease. The broad goal throughout the year of training is to develop a large knowledge background, communication skills, leadership skills and the technical skills necessary to provide comprehensive acute critical care to the full spectrum of congenital or acquired heart disease in neonates, toddlers, infants, children, adolescents and adults.
We have set forth specific goals and objectives and while all CICU advanced fellows will be expected to achieve these goals by the end of their fellowship, the curriculum will be adapted to the individual’s previous training, knowledge and competence. In addition to the time spent in the cardiac intensive care unit, this could include rotations in ECHO, cardiac anesthesia, perfusion, cardiac surgery, cardiac catheterization, electrophysiology, heart failure/transplant, general intensive care, ECMO and research.
The program provides an academic environment that allows the CICU Senior Fellow to be personally responsible for patients and their families as well as the CICU team, and to develop highly sophisticated skills in the management of medical, pre and post-operative and post-interventional patients with congenital and acquired cardiac illnesses- from the complex neonate to the adult- under the close supervision and mentorship of an experienced group of faculty members.
Clinical training is complemented by clinical and academic discussions, didactics, journal clubs, research and teaching opportunities.
Our institution uses the Pediatric Cardiac Intensive Care match listed on the San Francisco Match site, and all applications and necessary materials must be completed through this process. If you are not a USA citizen, include a copy of your ECFMG and bear in mind that you would need to acquire a J1 visa if selected as a candidate for our program. Incomplete or late applications will not be considered. It is your responsibility to ensure all required information has been received.
The timetable for the application process is detailed on the SF Match site, and the process will start on July 1st. Application instructions are listed on the Fellowship Programs page on the Pediatric Cardiac Intensive Care Society (PCICS) website. All applications should be submitted to Jen Miller, Administrative Services Coordinator, at Jen.Miller@childrenscolorado.org by September 1st.

Pediatric Heart Failure and Transplant Fellowship
The cardiomyopathy, heart failure, VAD, and transplant service at Children's Hospital Colorado is a rapidly growing and busy service. The team includes 6 physicians who directly participate in the education and training of 4th year fellows. We performed our 500th heart transplant in 2022, and we currently provide long-term follow-up care to about 200 heart transplant recipients. We directly manage patients with cardiomyopathy, heart failure, VAD, and transplant on the inpatient service. We are active in basic science, translational, and clinical research related to heart failure and transplant.
Our well-established ventricular assist device program provides circulatory support for infants and children of all sizes. Trainees can also spend 4 weeks at the University of Colorado Hospital learning from the adult VAD and transplant team.
Our cardiomyopathy clinic follows over 400 children with dilated, restrictive, hypertrophic, and non-compaction cardiomyopathy. The 4th year fellow will see patients in the cardiomyopathy clinics, including the neuromuscular clinic, cardio-oncology, and cardiovascular genetics clinic.
An important component of advanced heart failure and transplant training is HLA-typing/antibody testing, pathology, imaging and cardiac catheterization. Fellows will gain experience with interpretation of echocardiographic imaging of the post-transplant patient and cardiac catheterization including biopsy, coronary angiography, and intravascular ultrasound, interpretation of pathology, and interpretation of HLA testing.
Interested candidates should send with their applications:
- A copy of your curriculum vitae
- At least three letters of recommendation (1 of the 3 from the current cardiology fellowship program director)
