Pediheart Podcast #309: A Conversation With Surgical Living Legend, Dr. John Brown Aug 30, 2024

Show notes

This week we speak with Dr. John Brown who is the Harris B. Schumacker Professor Emeritus of Surgery at the University of Indiana. A congenital heart surgeon for over 45 years, Dr. Brown has performed more than 15,000 pediatric heart operations at Riley Hospital for Children and another 5000 heart operations in adults at IU and Methodist Hospitals. He performed the first pediatric heart transplant in Indiana and developed the first clinical use of the bovine jugular vein and valve for a pulmonary valve replacment in children. He also performed the only known twin to twin newborn heart transplant in the world. He has done and seen it all and has a unique perspective. How did he achieve so much and still have a succesful 56 year marriage to his wife Carol Ann? What is Dr. Brown most proud of in a career that is as prolific as his? What advice would he have have for the next generation? Prepare to be inspired by this master surgeon and friend and colleague of many in our field.

Pediheart Podcast #308: Can Preoperative Modeling Improve Fontan Design/Outcomes? Aug 23, 2024

Show notes

This week we delve into the world of the single ventricle when we speak with Dr. David Hoganson, Assistant Professor of Surgery at Harvard Medical School about a recent work he co-published with investigators from Boston Children’s Hospital on computational fluid dynamic modeling in the planning of the Fontan operation. Single ventricle heterotaxy patients with interrupted IVC are at enhanced risk for the development of pulmonary AVM’s due to flow maldistribution to the pulmonary arteries from the hepatic veins in a Fontan. Can a computational fluid dynamic model predict which operative approach would result in the most balanced hepatic venous flow distribution? Can this reduce the incidence of pulmonary AVM’s? How well did the models predict the actual pulmonary flow measured after surgery on CMR? Who beyond the heterotaxy patient might benefit from this approach? Dr. Hoganson offers us a peek into the world of personalized surgery in this week’s exciting episode.

Pediheart Podcast Replay of #242: Chronic Lower Extremity Venous Insufficiency In The Fontan Patient Aug 16, 2024

Show notes

This week we turn back the clocks to re-review a recent research letter from the team at the Harvard Congenital Heart Program about venous insufficiency in the Fontan patient. Why do patients with Fontan circulation develop chronic venous insufficiency and what are the implications of this problem in the Fontan patient? What sort of evaluation should be performed on the Fontan patient presenting with lower extremity venous changes? How worried should the cardiologist be when presented with a Fontan patient with these changes? These are amongst the questions reviewed on this topic with this week's guest, Associate Professor at Baylor University, Dr. Tony Pastor.

Pediheart Podcast #307: Impact Of Ischemic Time On Pediatric Heart Transplant Outcomes Aug 09, 2024

Show notes

This week we delve into the world of heart failure and transplantation when we review a recent PHTS study assessing the impact of ischemic time on outcomes of pediatric heart transplantation. What is considered to be a long ischemic time and what is the impact on outcomes in the pediatric patient undergoing transplant? Why does it appear as the impact of a longer ischemic time is less associated with graft failure in the present era in comparison to the past? What might be the impact of newer heart perfusion devices used to transport organs for transplant? These are amongst the questions reviewed with Professor of Pediatrics at U. Colorado, Dr. Scott R. Auerbach.

Pediheart Podcast #306: Assessing The LV In The Ebstein's Patient Aug 02, 2024

Show notes

This week we review a recent report assessing LV function and properties in the Ebstein's anomaly patient using CMR. How often is LV dysfunction observed in the Ebstein's patient who is about to undergo surgical Cone repair? How often did the echo underestimate LV dysfunction in comparison to the 'gold standard' CMR? How often is LV non-compaction observed when using strict criteria in this disease? Can CMR assessment of LV function preoperatively predict postoperative ICU course? These are amongst the questions posed to the first author of this week's work, advanced imaging fellow at U. Pittsburgh, Dr. Aditi Gupta.

Pediheart Podcast #305: Safety And Efficacy Of ICE For Pediatric And Congenital Ablations Jul 26, 2024

Show notes

This week we delve into the world of electrophysiology and review a recent report from the team at Primary Children’s hospital on the use of intravascular ultrasound for EP ablation procedures in children. How is this technology useful for ‘routine’ ablations in kids? Are there some forms of tachycardia where its use is more important than others? How does it lower procedural time or improve efficacy? We speak with Dr. Thomas Pilcher, chief of pediatric electrophysiology at Primary Children’s about his center's recent report in the use of this technology for ablation in children and those with congenital heart disease.

Pediheart Podcast #304: Pediatric Cardiology Pioneer Dr. Sylvia Griffiths - An Appreciation Jul 19, 2024

Show notes

This past week marked the passing of the great pediatric cardiology pioneer, Dr. Sylvia Griffiths. Dr. Griffiths was a trainee of Dr. Ruth Wittemore of Yale University and was one of the founders of the pediatric cardiology program at NY Presbyterian Hospital in the mid 1950's with Dr. Sidney Blumenthal. Her career spanned 7 decades, all at NY Presbyterian, Columbia University. She is remembered as a pioneering woman in medicine as well as a pioneer as a pediatric cardiologist. She is also remembered as a kind and warm colleague and friend. In today's 304th episode of Pediheart we review a 55 year old paper by Dr. Griffiths on outcomes of partial AV canal repair and speak with the present chief of pediatric cardiology at NY Presbyterian, Dr. Christopher Petit about the important role she played at Columbia. We then speak with Professor of Pediatrics at the Albert Einstein College of Medicine, Dr. Christine Walsh about the role she played in Dr. Walsh's life as well as the lives of so many patients, colleagues and friends. Her imprint will remain and she will always be missed and remembered fondly by all.

Pediheart Podcast #303: Outcomes Of Heart Transplantation Of The Single Ventricle Adult Jul 12, 2024

Show notes

This week we review a recent paper from last 2023 about outcomes of cardiac transplantation in the adult congenital heart patient (ACHD). Little has been written on this topic until this very robust and large scale report. How do single ventricle ACHD patients fair at transplant and how do they compare to non-ACHD heart transplant recipients? Why might 1 and 3 year outcomes not be a 'fair' method of assessing outcomes in this very high risk patient group? How do HLHS patient outcomes compare with other single ventricles? Are there better ways to measure risk in this patient group and how might the data in this work inform risk stratification and management of failing Fontan patients in whom transplantation is being considered? These are amongst the questions posed this week to the week's expert, Dr Daphne Hsu who is Professor of Pediatrics at the Albert Einstein College of Medicine at The Children's Hospital at Montefiore.

Pediheart Podcast Replay Of #231: Gender Inequity In Congenital Cardiac Electrophysiologist Salary Jul 05, 2024

Show notes

This week we go back in time to 20222 to re-review an episode focusing on gender disparities in salary in the field of congenital electrophysiology. To what degree are female electrophysiologists paid less than their male counterparts despite similar levels of education, work effort and seniority? What interventions could be enacted to help 'mind the gap' and level the playing field in this regard? We speak with the chief of pediatric electrophysiology at The Children's Hospital of Philadelphia, Professor Maully Shah, who is the first author of this week's research letter. doi: 10.1016/j.jacep.2022.02.011

Pediheart Podcast #302: Ductal Stenting In a Low Resource Environment Jun 28, 2024

Show notes

This week's topic is ductal stenting in a low resource environment. We review a recent report from the team at Amrita Institute in Kerala, India about their large, over 10 year experience in ductal stenting. Why has this approach superceded BTTS in this environment? How does the team determine if a patient is a candidate and what morphologies of duct would be inappropriate for intervention? How does the team manage PGE prior to ductal stenting to allow that perfect balance between pulmonary blood flow and ductal constriction to improve procedural success? What can operators in the west learn from the experience of these operators? We review these questions and more with the first author of this work, Dr. Navaneetha Sasikumar who is Associate Professor of Pediatrics at the Amrita Institute.
