• Pediheart Podcast #333: Complications With The Alterra Prestent - Reason For Concern?

  This week we review a recent report of 4 patients with serious complications related to either perforation or external compression from the distal tines of the Alterra prestent when used for transcatheter pulmonary valve replacement. We speak with Dr. R. Allen Ligon, interventional cardiologist at Children's Healthcare of Atlanta/Emory University about a recent multicenter report of rare complications seen with this prosthesis. How common are perforations seen with this device and how often are these clinically silent? What should be done for clinically silent prestent perforations? What sort of surveillance of all patients with this device is warranted after successful placement? These are amongst the questions posed to Dr. Ligon and discussed this week. DOI: 10.1016/j.jaccas.2024.102836

• Pediheart Podcast #332: A Novel 21st Century Cardiology Fellow Educational Approach - Shared Learning Across The Globe

  This week we review a report from the teams at University College, Dublin and Texas Children’s Hospital about a collaborative approach to education in which two centers across the globe participate in a shared fellow learning conference. In this conference which is aimed at fellow education, topics are chosen and discussed with facilitated learning from faculty at both sites. What can be gained for fellows on opposite sides of the Atlantic that cannot be learned from exposure to just their one site? How did this approach help fellows learn about how to deal with uncertainty in decision making? How did this trans-continental learning approach enhance patient and team communication? These are amongst the many questions posed to senior cardiologist and senior author of this week’s work, Professor Colin McMahon of University College, Dublin, Ireland.   ·         DOI: 10.1007/s00246-024-03469-x

• Pediheart Podcast #331: Latest Innovations In Pacing With Dr. Charles Berul

  This week we review a recent review paper on newest innovations and literature on pacing in pediatric patients and learn a bit about such diverse pediatric pacing topics as:Use of the Medtronic Micra device in an off-label manner for epicardial pacing in small infantsNovel, less invasive approaches to placing epicardial leads in small childrenThe role of leadless pacing in the pediatric or CHD patientConduction system pacing in 2025 in the congenital patientThe above are amongst the potpourri of pacing topics that we review with noted congenital electrophysiologist, Dr. Charles Berul of Children's National Hospital in Washington, DC in a co-branded episode with the SADS Foundation.

• Pediheart Podcast Replay of #227: Cardiac MRI Computational Fluid Dynamics Assessment And Relation To Quality Of Life In The Fontan Patient

  This week we step back in time 3 years ago to review an important cardiac MRI report on Fontan geometry and hemodynamics as measured by computational fluid dynamic analysis. How do factors like Fontan geometry or 'power loss' relate to quality of life for the Fontan young adult patient? How do these data inform imaging in the operating room during these palliations? We speak with the first author of this work, Associate Professor of Pediatrics at U. Penn, Dr. Laura Mercer-Rosa about this important and intriguing work. https://doi.org/10.1016/j.athoracsur.2022.01.017

• Pediheart Podcast #330: Can Early Postoperative Transverse Aortic Arch Dimension Following Coarctation Surgery Predict Late Hypertension?

  This week we review a work from the department of cardiology and department of cardiac surgery at Boston Children's Hospital on late hypertension in patients following coarctation repair. Late hypertension has been associated previously with late transverse aortic arch Z score but can this be predicted by the immediate postoperative transverse aortic arch Z score also? What factors account for late hypertension in the coarctation patient? Should more patients have their aorta repaired from a sternotomy? Dr. Sanam Safi-Rasmussen, who is a PhD candidate at Copenhagen University, shares her insights from a work she performed while a research fellow at Boston Children's Hospital. DOI: 10.1016/j.jtcvs.2024.08.049
