Pediheart: Pediatric Cardiology Today

This week we review a recent work from the team at Children's LA about an unusual form of pre-excitation and use this as a place to launch a discussion about pre-excitation. What sorts of pathways cause pre-excitation? Should all pre-excited patients undergo formal testing? Should all pathways be ablated? How can we invasively or non-invasively assess these patients and are these approaches reliable? We have 2 noted experts on this topic - Professor Michael Silka of USC and Professor Steven Fishberger of Spokane, Washington and U. Miami. This is a rare opportunity to hear 2 'gurus' on pediatric electrophysiology 'riff' on a topic about which they each have encyclopedic knowledge. https://doi.org/10.1017/s1047951121000056

This week 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

This week we play a live podcast session from SCAI 2021 (April 30, 2021) on the topic of balloon angioplasty for native aortic coarctation in infants aged 3-12 months. We speak with the senior author of this recent work from Toronto Sick Children's Hospital - Professor Rajiv Chaturvedi. How often were complications encountered? How do results compare with surgical repair? Is high pressure required for these dilations? Professor Chaturvedi provides all the answers and more this week! doi: 10.1161/CIRCINTERVENTIONS.120.008938

This week we speak with Professor Eric Rosenthal of Evelina Children's Hospital in London, England from a session at SCAI 2021. Who is a candidate for closure of a superior sinus venosus ASD in the cath lab and how is this determined? If there is a residual shunt, how much is too much? How did Professor Rosenthal embark on this approach and what have been the results? What percentage of these patients are candidates for this novel approach? This is a rare opportunity to have the author present their own data followed by questions from Dr. Pass and Dr. Aimee Armstrong of Nationwide Children's Hospital. https://doi.org/10.1016/j.jacc.2019.12.070

This week we have a special treat in playing a session from the SCAI meeting from today, April 29, 2021! We speak with Professor Julie Vincent of Columbia University and Professor Chuck Mullins of Baylor College of Medicine. Both speak about their early lives, how they chose to become physicians and how life in retirement is treating them. What role did teamwork play in each doctors' professional life? How did Dr. Mullins design the 'Mullins sheath'? These are amongst the many topics we touch upon in this 'slice of life' conversation that was recorded today from the 2021 Scientific Sessions of SCAI which continues through May 1, 2021!

In this replay of episode 80 from 2019, we review a study from The University of Toronto on the impact of timing of the arterial switch operation for DTGA on brain growth and neurodevelopmental outcomes. Can the timing of this surgery impact these outcomes? What is the reason for this? Is it rational to perform this surgery early to improve neurological outcomes? How important is the conduct in the OR versus the ICU? These are amongst the questions we address with Professor Jane Newburger of Harvard University - Boston Children's Hospital this week! doi: 10.1161/CIRCULATIONAHA.118.037495

This week we delve into the world of healthcare disparities and ACHD when we review a recent 'big data' study on levels of insurance coverage amongst ACHD patients and the impact of the affordable care act ("Obamacare") on this metric. To what extent did the enactment of this program increase insurance coverage for ACHD patients? How do their levels of coverage compare with other chronic illness patients such as sickle cell disease or cystic fibrosis? Were all ACHD patients affected similarly from the advent of the ACA? We speak with U. of Michigan ACHD fellow Dr. Katherine Salciccioli about this important work from the group at Texas Children's Hospital. doi: 10.1002/bdr2.1878

This week in a co-branded episodes with the SADS Foundation (SADS.org) we speak with Professor Johannes von Alvensleben of U. Colorado about a recent PACES study on the outcomes of S-ICD's in children and ACHD patients. What are the challenges to their use and who is a good candidate? What is involved in screening patients for an S-ICD and why do children and ACHD patient seem to 'screen out' more than the general population? What are the challenges to their implantation and what is coming down the pipeline in terms of innovation with these devices? Dr. von Alvensleben shares his insights this week. doi: 10.1016/j.jacep.2020.07.010

This week we explore a recent work assessing the degree of anatomical concordance between neonatologist-performed echocardiograms and those by pediatric cardiology. What is the role of a hemodynamic consultation team in the management of the transitional physiology of the newborn? How do neonatologists use echocardiography in real time to help manage complex physiological problems of the newborn? What training is needed to do this and how does the neonatal team collaborate with cardiology to provide optimal neonatal physiological support and care? We speak with 2 experts to get the perspective of the neonatologist and cardiologist. Senior author and neonatologist Professor Patrick McNamara of University of Iowa and noted cardiac imaging expert, Professor Leo Lopez of Stanford University share their deep insights this week. doi: 10.1016/j.echo.2020.11.005

We speak with hematology researcher, Dr. Chantal Attard of The Murdoch Children's Research Institute of The University of Melbourne about a recent cross-sectional study comparing multiple factors in patients with Fontan circulation on aspirin vs. warfarin. What were the demonstrable differences in outcome? Are there ways to make the use of warfarin more safe? What about novel anticoagulants - what is their possible role and what evidence exists for their use in this setting? Dr. Attard provides many key 'takeaways' this week! doi: 10.1016/j.jtcvs.2020.12.102

This week in a co-branded episode with the SADS Foundation (SADS.ORG), we speak with Professor Peter Schwartz of University of Pavia about a recent work he authored on the topic of changes in repolarization amongst well trained athletes. Can athletic training masquerade as LQTS causing prolongation and/or abnormalities in the QT interval? How can these patients be properly identified and not 'lumped' into the LQTS 'pile'? This is a very important work by one of the foremost authorities on the planet on LQTS and Professor Schwartz also shares with us how he became interested in this topic 50+ years ago as well as some pearls for clinical investigators at the start of their careers. One of the best and most inspirational interviews of the entire 150 episode series! doi: 10.1161/CIRCULATIONAHA.120.048916
