Pediheart: Pediatric Cardiology Today

This week we review a recent survey study assessing the beliefs of fetal cardiologists and how these may influence the content and conduct of their counseling. Do most fetal cardiologists review all options including intervention, comfort care and pregnancy termination? Should there be a mandate that all do? Is it realistic or appropriate to ask a fetal cardiologist to suggest an option when they do not believe it to be a reasonable or correct choice? We speak with two of the authors of this work and they are Dr. Joanne Chiu of Harvard University and Dr. Caitlin Haxel of The University of Vermont.  * DOI: 10.1002/pd.6706 [https://doi.org/10.1002/pd.6706]

This week we review an episode from 3 years back and delve into the world of adult congenital heart disease when we review a recent work from the ACHD team at UCSF that assesses the impact of BMI on clinical outcomes in the single ventricle adult Fontan patient. What is the cause of elevation in BMI in some Fontan patients? Is obesity the only explanation? Is BMI a modifiable risk factor for our Fontan patients and should exercise be 'prescribed' for these patients? If so prescribed, what type of exercise is best for the Fontan patient? This week's work's senior author, Dr. Anushree Agarwal, Assistant Professor of Medicine at UCSF, shares her insights into this important topic.  DOI: 10.1161/JAHA.122.026732 Also mentioned in today's episode is episode #222 with Dr. Dan Halpern of NYU medical center (https://www.stitcher.com/show/pediheartpediatric-cardiology-today/episode/pediheart-podcast-222-impact-of-cardiac-rehab-on-exercise-tolerance-in-the-achd-patient-206781483)

This week we review a recent work from the "Women In Pediatric Cardiology" group which is a 4 year old initiative to help lift up women pediatric cardiologists through the fostering of connections and also via mentorship programs. Why did this program develop and what are the most pressing issues affecting female pediatric cardiologists? What are the best solutions to help address gender inequities in our field? We speak with two co-authors of this week's work, Drs. Sarah Ford of Brown University and Kristin Laraja of University of Massachussetts. For those interested in participating in their work, feel free to email  Pediheart@gmail.com and your information will be passed along to the authors.  * DOI: 10.1007/s00246-024-03576-9 [https://doi.org/10.1007/s00246-024-03576-9]

This week we review a recent multicenter, randomized trial pitting 2 different immunosuppressive therapeutic approaches against each other. How did a novel approach of everolimus + low dose tacrolimus compare to more standard MMF + standard, higher dose tacrolimus in avoidance of major adverse transplant events or complications? How did this first ever prospective trial in the pediatric heart transplantation world start and how difficult was it to perform in the absence of corporate or NIH support? Why can these data help inform FDA labelling for this novel approach and why is this important? Dr. Kevin Daly of Boston Children's Hospital shares his deep insights into this work this week! * DOI: 10.1001/jama.2025.14338 [https://doi.org/10.1001/jama.2025.14338]

This week we review a recent report of the use of phenoxybenzamine for the reduction of SVR in children undergoing congenital heart surgery in India. How does this agent work and what might be the advantage versus other agents like nitroprusside or milrinone which are more commonly used? How does the cost of this agent (or phentolamine) compare with newer agents? We speak with Dr. Rohit Loomba of Lurie Children's Hospital. For those interested, in addition to working as a critical care cardiologist, Dr. Loomba is also a noted cardiac morphologist and his wonderful videos can be seen at the following web address: https://www.youtube.com/@Talking_Hearts Today's paper: DOI: 10.4103/jpbs.jpbs_868_25
