Pediheart Podcast Replay of Episode #164: Cone Reconstruction For Ebstein's Anomaly Mar 10, 2023

Show notes

In this replay episode from 2021, we review a recent work on CMR outcomes pre and post cone reconstruction of the tricuspid valve in Ebstein's anomaly. How durable of a repair is this operation? Is there evidence for ventricular remodeling? Is there an optimal age to perform this surgical procedure? How should arrhythmia risk be assessed prior to surgery? These are amongst the many questions reviewed by and posed to Professor Pedro DelNido of Harvard University. This is a rare opportunity to speak with one of the finest congenital heart surgeons in the world today and a noted expert on the cone repair. doi: 10.1016/j.jtcvs.2020.10.124

Pediheart Podcast #243: A Novel Approach To Transcatheter SAPIEN Pulmonary Valve Implantation Mar 03, 2023

Show notes

This week we review a recent report of a new technique to implant SAPIEN valves for transcatheter pulmonary valve replacement in which 1-3 stents are implanted simultaneously with the SAPIEN valve. What are the potential benefits or disadvantages of this approach and who might be a better candidate for this method? Why is a stent needed outside of the relatively strong SAPIEN prosthesis and how does the team in San Diego choose bare metal vs. covered stents when performing this procedure? We speak with pediatric interventional cardiologist Dr. Jessica Heibel of Pediatrix in San Antonio, Texas about a recent work she co-authored with the team at Rady Children's Hospital in San Diego, California. Dr. Heibel reviews many of the finer points of transcatheter valve implantation this week.

Pediheart Podcast #242: Chronic Lower Extremity Venous Insufficiency In The Fontan Patient Feb 24, 2023

Show notes

This week we delve into the world of adult congenital heart disease when we 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, Assistant Professor of Clinical Pediatrics (Cardiology) at Yale University, Dr. Tony Pastor.

Pediheart Podcast #241: A Conversation About The 2023 World Congress Of Pediatric Cardiology And Cardiac Surgery Feb 17, 2023

Show notes

In this week's special episode that is a combination of the Pediheart Podcast and PCICS Podcast, we speak for the entire episode with Professor of Pediatrics Dr. Gil Wernovsky of Children's National. Dr. Wernovsky is the Co-Chair of the upcoming World Congress of Pediatric Cardiology and Cardiac Surgery and shares with us all of the exciting plans for this 'meeting of meetings' that will be staged from August 27th-September 1st in Washington, DC. This is the first World Congress in the US since 1985. Co-hosts Deanna Tzanetos, Jill Zender, David Werho, Lillian Su and Sadie Rodriguez discuss with Dr. Wernovsky why this upcoming meeting will be perhaps the largest congenital heart meeting in history with 'something for everyone'.

Pediheart Podcast #240: Atrial Standstill In The Pediatric Patient Population Feb 10, 2023

Show notes

This week we delve into the world of electrophysiology when we review a recent multicenter work on the rare topic of atrial standstill. What is atrial standstill and how does it differ from SA node dysfunction? What risks are associated with this condition and how can they be mitigated? Are there factors in an atrial standstill patient that might prompt implantation of a primary prevention ICD? We speak with the first author of this week's work, Dr. Taylor Howard who is Assistant Professor of Pediatrics at Baylor College of Medicine and an attending physician in pediatric electrophysiology at Texas Children's Hospital about his most recent work.

Pediheart Podcast #239: Reductions In Brain Injury Following Neonatal Congenital Heart Surgery Feb 03, 2023

Show notes

This week we delve into the world of neonatal congenital heart surgery and review a recent work on changes in the incidence of brain injury following congenital heart surgery. How common is it to see brain injury on the MRI's in this patient group? How have incidences changed over time and what is the likely reason for this? Can the types of inotropic agents used in the postoperative period potentially explain some of the improvements in outcomes that have been observed and what is the proposed mechanism for this? We speak with this week's first author, noted authority on neurodevelopmental outcomes of patients undergoing neontal heart surgery, Associate Professor of Pediatrics at UCSF, Dr. Shab Peyvandi.

Pediheart Podcast #238: Outcomes of Non-Cardiac Surgery In The ACHD Patient + A Conversation With Dr. Alexandra Lansky Of JSCAI Jan 27, 2023

Show notes

This week we delve into the world of ACHD when we review a recent work on outcomes of non-cardiac surgery in the ACHD patient. How do ACHD patients fare in comparison to their non-ACHD cohort undergoing non-cardiac surgery? What can be done to improve outcomes in this patient group? We speak with the senior author of this work, Dr. Peyman Benharash, who is Associate Professor of Surgery at UCLA. DOI: 10.1136/heartjnl-2022-321512
Also joining us this week is Dr. Alexandra Lansky of Yale University who is also the Editor-in-Chief of JSCAI which is the newest interventional cardiology journal and the official journal of SCAI. Dr. Lansky shares with us her hopes for the new journal and also the role that congenital interventions will play in this journal. Visit JSCAI.org to see what 'all the fuss' is about!

Pediheart Podcast Replay of #134: Outcomes Of Valve Replacement In The Single Ventricle Patient Jan 20, 2023

Show notes

This week we replay a 2020 episode in which we reviewed a then recent PCCC study assessing outcomes of single ventricle patients who have undergone replacement of the AV or semilunar valve. We speak with Professor Geetha Raghuveer of University of Missouri-Kansas City about this work she co-authored. Outcomes are generally poor in this patient group but are there lessons that can be gleaned from the data regarding optimal timing for repair or replacement of valves in this patient group? This is a great follow-up of episode # 58 from 3.5 years ago. See you next week with a brand new episode! doi: 10.1007/s00246-019-02234-9.

Pediheart Podcast #237: Open Chest Duration And Its Relation To Surgical Site Infection Jan 13, 2023

Show notes

This week we return to the topic of congenital heart surgery when we speak with Dr. John Iguidbashian who is a resident in surgery at U. Colorado. Dr. Iguidbashian reviews a recent paper he co-authored on the topic of the relation of duration of open chest following heart surgery to the development of surgical site infections (SSI). How long is 'too long' when it comes to an open chest and the risk for infection? Is the duration of an open chest following surgery a 'modifiable' risk factor? Are there other factors that might be associated with SSI in this setting other than duration of open chest? Dr. Iguidbashian shares his insights this week. https://doi.org/10.1007/s00246-022-03088-4.

Pediheart Podcast #236: The 'Case' For Partial Heart Transplantation In Children Jan 06, 2023

Show notes

This week we delve into the world of partial heart transplantation when we review a recent paper that discusses the rationale for its potential use in children, particularly in infants. We speak with the work's senior author, Dr. T. Konrad Rajab of the Medical University of South Carolina about the potential benefits of this approach. Who might be a candidate for this approach? What are the theoretical benefits of this approach to transplantation? How many 'partial heart' transplantations have been done to date in the US? What might be different about transplanting 'parts' of hearts rather than entire hearts? Dr. Rajab provides us with his deep insights this week. doi: 10.1111/jocs.17050
