Pediheart: Pediatric Cardiology Today

Pediheart Podcast #384: A Conversation About Pediatric Cardiac Critical Care With Drs. Anthony Rossi and Gil Wernovsky

This week we speak with 2 pioneers in the field of pediatric cardiac critical care, Dr. Anthony Rossi and Dr. Gil Wernovsky. Both were present at the very start of the field of cardiac critical care for children. What was it like in an era before transesophageal echocardiography or even postoperative echo? Why was the advent of the bidirectional cavo-pulmonary anastomosis such a game changer in the care of children with heart disease? What do Drs. Rossi and Wernovsky think were the most important improvements to care for children with heart disease in their 35+ year careers? What about care today troubles these intensive care gurus? This is a rare opportunity to speak with two who have seen and done it all in cardiac critical care for children. For those interested to hear Dr. Rossi speak about goal directed therapy, take a listen to episode 21 and episode 200 of this podcast!

Pediheart Podcast #383: Using Virtual Reality And 3D Modelling For Planning Complex Congenital Heart Surgery

This week we review a recent report from the team at Amrita Institute in Cocchin, India about their use of extended reality and virtual reality as well as heart model printing to aid in planning for complex intracardiac baffles for the treatment of complex congenital heart defects. What was the process used to provide actionable advice in the operating room during surgery? How has the team in southern India created a workflow that can accurately predict this complex anatomy and the patches needed to successfully septate complex hearts? We speak with the director of the 3D imaging group at Amrita, Professor Mahesh Kappanayil about this remarkable achievement of imaging in collaboration with surgery.  * DOI: 10.1016/j.jtcvs.2026.03.616 [https://doi.org/10.1016/j.jtcvs.2026.03.616]

Pediheart Podcast #382: Outcomes Of Mavacamten In Adolescent Patients With HCM

This week we review a landmark paper from the NEJM by the SCOUT-HCM study group assessing the impact of mavacamten on HCM in the adolescent patient. How does this agent work and what impact did it have on the LVOT gradients in obstructed HCM teens? Does this agent affect other biomarkers associated with more obstruction in this setting? Who is a good potential candidate for the use of this agent? Why must the EF be carefully monitored while using this agent? Dr. Joseph Rossano, Professor of Pediatrics at The University of Pennsylvania and the chief of pediatric cardiology at The Children's Hospital of Philadelphia joins the podcast to discuss this groundbreaking work. doi: 10.1056/NEJMoa2601103

Pediheart Podcast #381: Evaluation And Management Of Unexpected AV Block In Children

This week we feature a collaboration episode between the Pediheart Podcast and the PedsCrit Podcast in which pediatric critical care experts Drs. Alice Shanklin of Northwell Medical Center and Dr. Zac Hodges of UT Southwestern discuss the evaluation and management of heart block in children. What should the clinician be thinking when encountering a previously healthy child with heart block? When is pacing indicated and how should it be performed? Who is a candidate for transvenous or transcutaneous pacing, who is not and why? Drs. Pass, Shanklin and Hodges review many aspects of this in an episode from the PedsCrit Podcast.  https://www.pedscrit.com/

Pediheart Podcast #380: Does Phenylephrine Reliably Lower Heart Rate During Pediatric Congenital Heart Coronary CT Scans

This week we review a recent work from the CT group at NY Presbyterian assessing the impact of phenylephrine during pediatric congenital CT scans to lower heart rate. Why is a lower heart rate better for CCT's? Should this agent be routinely employed for this indication during CT scans in children? Dr. Yosef Cohen, pediatrics resident at the Children's Hospital at Montefiore shares his insights from a recent work he co-authored.  doi: 10.1093/ehjimp/qyag023. eCollection 2025 Aug.
