Pediheart: Pediatric Cardiology Today

This week we speak with living legend of cardiology, Dr. Michael Freed about his life and also his landmark paper in 1981 on PGE1. How did Dr. Freed come to conduct one of the first multi center trials of an agent in pediatrics? What was life like in the world of pediatric cardiology prior to PGE1? What is Dr. Freed up to today? What advice does he have for the younger generation? This is a rare o...

This week we review a recent work from the team at NY Presbyterian on SVT and a possible role it may rarely play in sudden cardiac arrest in children. When a patient does not have an obvious cause of arrest, is SVT a possible etiology and should invasive EP testing be considered? We speak with the senior author of this work, Dr. Leonardo Liberman about his thoughts on SVT as a possible cause of ar...

This week we review the concept of stenting the pulmonary veins and we speak with Assistant Professor of Pediatrics at Baylor Medical College, Dr. Melissa Webb about a recent work she co-authored on this topic. Dr. Webb reviews a novel approach to shortening Palmaz stents and then reviews for us the rationale for stenting PV's and also discusses how these patients are longitudinally followed at Te...

In this milestone 200th episode of Pediheart, we review a 2005 paper from the team at Nicklaus Children's Hospital on how lactate level was used to monitor oxygen delivery and consumption in the postop congenital heart patient and the impact that a protocol involving frequent monitoring and response to this value improved outcomes in the pediatric CICU. Joining us is the first author of the work,...

This week's replay episode is co-branded with SADS.ORG and is on the topic of pre-participation screening from 2 years back. Can the ECG offer important benefits vs. the standard 14 point AHA H&P approach? Which approach was more effective in 'real life'? We speak with Professor Robert Campbell of Emory University this week to delve into this contentious and important topic. DOI: 10.1016/j.hrthm.2...

This week we delve into cardiac surgery and review a recent paper from Rady Children's Hospital about patch material and outcomes in the CHD surgical patient. What are the reasons that glutaraldehyde is used to treat patches used for surgery and what are the potential benefits and disadvantages? What sorts of patches are best for what indications? Are there data to suggest superiority of one patch...

This week we review a recent work from Utrecht University in The Netherlands on the topic of postoperative pericardial effusion following congenital heart surgery.

We speak with the first author of this work, Poznan University of Medical Sciences student, Nirmiti Somani about this practica...

This week we delve into the world of the single ventricle patient when we speak with Dr. Adam Lubert of Cincinnati Children's Hospital Center about a recent work he co-authored on MRI imaging of the liver in the Fontan patient. Can simple liver metrics help predict hemodynamics or even outcomes in the single ventricle patient with a Fontan? What is the optimal way to image the liver in this patien...

This week we travel back in time to 1991 to review one of the first collaborative projects between Dr. Lisa Hornberger of U. Alberta and the legendary pediatric cardiology investigator, Dr. David Sahn. In this work on tricuspid valve disorders with TR and their diagnosis in fetal life, we learn about our first understandings of this complex physiology and problem and use this as starting point to...

In a replay of episode #90 from 2019, we re-review a recent report from the CTOTC-04 study group assessing the impact of novel anti-rejection approaches which generally markedly reduce or remove steroids in the prevention of rejection. How are rejection rates affected by such an approach? Did incidences of diabetes or PTLD differ when using this form of steroid reduced approach in the 'low immunol...

This week we delve into general pediatric cardiology and discuss those mild abnormalities that are sometimes seen on echo in the newborn nursery. Which of these minor findings in healthy newborns should be monitored and who can be 'discharged' from cardiology follow-up? Are there data to help inform these decisions? Dr. John Hokanson, Professor of Pediatrics, U. Wisconsin, shares his insights this...

This week we review a recent CMR study assessing changes in myocardial fibrosis identified with CMR T1 mapping seen in TOF patients with a single nucleotide polymorphism (SNP) of hypoxia inducible factor 1 alpha. Is myocardial fibrosis in the TOF patient due to hemodynamic factors alone or are there genetic factors that predispose to differences that can be measured on CMR? Professor Lars Grosse-W...

Melody valves have been demonstrated to be associated with a small but consistent rate of endocarditis. Are there factors that might help predict who would need surgical explantation versus those who can be medically managed without surgery? Dr. Arpine Davtyan, senior cardiology fellow at Rady Children's Hospital shares insights from her recent multicenter, retrospective study on this topic. doi:...

Dr. George Ofori-Amanfo, Division Chief of Pediatric Critical Care Medicine in the Jack and Lucy Clark Department of Pediatrics at the Icahn School of Medicine at Mount Sinai and at the Mount Sinai Kravis Children's Hospital, died last week after a very long illness. To honor him, we go back to episode #2 in 2018 in which Professor Ofori-Amanfo shares his insights into the delivery of cardiovascul...

This week's episode, the final of 2021, is on personal finance and we speak with noted personal finance expert Paul Merriman about strategies to improve investing results within a retirement account. Mr. Merriman reviews index funds, the value of these over 'actively managed' funds, and his thoughts on 'target date funds'. Finally, he shares a strategy that may improve the outcome of a target date...

This week we revisit episode 135 where we discussed the topic of mortality attributable to CHD in the US and persistent racial/ethnic disparities over the past 20 years. We speak with Professor Keila Lopez of Texas Children's Hospital about a recent large scale, 'big data' study she co-authored about this topic and review the reasons for these disparities and think about possible remedies. An esse...

This week we delve into the world of congenital heart disease when we review a recent work from the team at Boston Children's Hospital on the long term outcomes of truncal valves in the setting of truncus arteriosus. Who amongst truncus patients is at risk for the development of truncal regurgitation or a need for reintervention? Are there predictors that might help forecast patients who should be...

This week we delve into the coronavirus pandemic and specifically the multisystem inflammatory syndrome in children (MIS-C) following COVID-19 infection. When there was significant initial cardiac involvement seen in the setting of MIS-C, what findings are common in the CMR of patients 6+ months later? How common is delayed enhancement seen and how does this compare with findings seen in other myo...

This week we turn to a recent work from the group at Texas Children's Hospital about IV sotalol and the treatment of junctional ectopic tachycardia (JET). How did sotalol fair in comparison to IV amiodarone for the treatment of this potentially lethal postoperative arrhythmia? What differences were observed? How should IV sotalol be dosed and who is or is not a candidate? We speak with the first a...

In this week's special 'fellow takeover episode', Dr. Sarah Pradhan, sometime co-host of Pediheart and third year cardiology fellow at Cincinnati Children's Hospital, speaks with Professor Roberta Williams of USC about her long and illustrious career as a pioneer in both echocardiography as well as pediatric cardiac critical care.
