Pediheart Podcast #124: Does Non-Invasive Loss Of Preexcitation Equal Low Risk For Sudden Death In WPW? Jul 03, 2020

Show notes

This week we review a recent large database study of WPW with particular interest in the patient with intermittent preexcitation. Traditionally, this finding has been considered a sign of low risk. Is this true? Who deserves formal invasive EP testing in this setting? Should all WPW pathways be ablated? These are amongst the many interesting questions discussed with Assistant Professor of Pediatrics - University of Alberta - Dr. Carolina Escudero. doi: 10.1016/j.hrthm.2020.05.035

Pediheart Podcast #123: A Novel Autoantibody Test For Brugada Syndrome Jun 26, 2020

Show notes

This week we speak with Professor Robert Hamilton of University of Toronto about a recent potentially groundbreaking work on a novel approach to the diagnosis of Brugada syndrome using an immunological test. How accurate is this test for diagnosis of this often elusive syndrome? Is autoimmunity the cause of disease or are the antibodies just a marker of disease. What's the latest on Professor Hamilton's work on testing for ARVC (reviewed previously in episode 43)? Dr. Hamilton provides us with lots of answers this week. For those interested in collaborating in his studies, his email and that of his research coordinator are in the podcast this week. doi: 10.1093/eurheartj/ehaa383

Pediheart Podcast # 122: Morphology Of Ductus Arteriosus And Its Relationship To Ductal Stenting Jun 19, 2020

Show notes

This week we speak with Professor Marc Gewillig of Leuven, Belgium about a recent paper he co-authored on the topic of the relation of ductal morphology to success at endovascular stenting. Are there some morphologies that are more difficult than others? How is the length of the ductus optimally estimated when choosing a stent length? Dr. Gewillig shares many pearls this week. doi: 10.1002/ccd.28725

Pediheart Podcast #121: Outcomes Of Fontan Palliation In The Down Syndrome Patient Jun 12, 2020

Show notes

This week we review the outcomes of Fontan palliation in the Down Syndrome patient. We speak with Assistant Professor of Pediatrics Dr. Lauren Sarno of East Carolina University about a recent work she co-authored on a complex statistical analysis she performed from the STS database. What accounts for worse outcomes in this patient population? Prepare to be surprised by the information provided this week! DOI: 10.1016/j.athoracsur.2019.07.085

Pediheart Podcast #120: A History of Pediatric Heart Transplantation With Dr. James Kirklin Jun 05, 2020

Show notes

This week we have the rare opportunity to speak for the entire podcast with a pioneer in pediatric heart transplantation and VAD support - Professor James Kirklan of University of Alabama. Dr. Kirklin shares his experiences in forming the PHTS and other organizations devoted to mechanical assist devices in adults and children and how he started the process of multi-institutional studies to answer important questions in surgery and medicine. Dr. Kirklin shares his thoughts regarding the future in this field and also offers some general career and life advice. This is a 'not to be missed' chance to learn from one of the greats of our time in medicine!

Pediheart Podcast Replay #21: CICU Management Of The Complex Newborn Following Surgery May 29, 2020

Show notes

This week we replay one of the most listened to episodes of the early part of this podcast history - episode 21 with Dr. Anthony Rossi. Professor Rossi is the Director of Pediatric Cardiology at Nicklaus Children's Hospital in Miami, Florida and is one of the leaders and pioneers in the field of pediatric cardiac critical care. We sit down with Dr. Rossi to review his approach to the assessment and management of the single ventricle patient following stage I palliation. The clinical 'pearls' come fast and furiously from Dr. Rossi - this is one to have pen and paper available to take notes! An inspiring figure to usher out the month of May!

Pediheart Podcast # 119: Intraoperative Methadone Reduces Opiod Usage During And After Congenital Heart Surgery May 22, 2020

Show notes

This week we enter the world of cardiovascular anesthesiology to review a recent work from Duke University on the results of the use of IV methadone during cardiac surgery in children. Does this agent result in reductions in postoperative opioid usage while affording similar analgesia? What are the advantages of this agent in this setting? How much should the cardiologist worry about the impact of methadone on the QT interval? We speak with the first author of this work, Assistant Professor of Anesthesiology at UNC, Dr. Annika Barnett. doi: 10.1111/pan.13903

Pediheart Podcast #118: Effect Of Maternal Hypertension On RV and LV Size And Dimensions Of The Offspring May 15, 2020

Show notes

This week we enter into the worlds of fetal cardiology and preventative cardiology to review a recent work from Professor Paul Leeson of Oxford University on the topic of pregnancy induced hypertension and the impact this plays on the cardiovascular health of the offspring. How does this form of HTN affect the structure of the RV and LV in the offspring and why might this explain the increased rates of adult HTN in the offspring of women who were hypertensive during pregnancy? Dr. Leeson provides many interesting insights and context this week. doi: 10.1161/JAHA.119.014586

Pediheart Podcast #117: Novel Radial Sheaths With Large ID And Small OD For Pediatric Femoral Catheterization May 08, 2020

Show notes

This week we review a recent work from the team at Mercy Children's on the variability of sheath outer diameter (OD) amongst various sheaths. Can novel 4Fr adult radial sheaths have similar OD to more standard 3.3Fr pediatric sheaths? What are the trade-offs in using a radial sheath for this indication in a newborn? Senior author Dr. Abhay Divekar of Rocky Mountain Pediatric Cardiology shares his insights this week. doi: 10.1002/ccd.28825

Pediheart Podcast #116: Anatomical Aspects of Ebstein's Anomaly And Their Relation To Arrhythmia May 01, 2020

Show notes

On this episode we speak with Professor Edward Walsh of Harvard University about a recent work he co-authored on Ebstein's anomaly. Can review of pathological specimens offer some insights into why ablations in this patient group are so challenging? Is there an optimal age or size to perform an ablation in this patient group? Why are these ablations so difficult? Dr. Walsh, Director of the Arrhythmia Service at Boston Children's Hospital, shares his deep insights this week. doi: 10.1016/j.hrthm.2020.01.013
