Pediheart: Pediatric Cardiology Today

This week we review a recent editorial commentary by Drs. Belinda Gray, Rachel Lampert and Michael Papadakis on the concept of the personalized emergency action plan for the patient with genetic heart disease who is 'returning to play' in vigorous sports. With newer data demonstrating that risk for SCA or SCD is perhaps not as high as was once thought in this setting of sport, can the development...

This week we review a study assessing the impact of bundle branch block (BBB) on exercise tolerance amongst the single ventricle Fontan patient cohort. Why would this be associated with worse outcomes for exercise? How should the cardiologist use this datum of BBB in a single ventricle patient to inform clinical decision making in this patient group? Why is cardiac resynchronization therapy so cha...

In this replay episode from 2023, we return to the world of ACHD when we review a recent German research paper on the prevalence of PTSD symptoms amongst the ACHD patient group. How common is this type of symptom observed in the ACHD patient group? What contributes to the high prevalence (17-20.5%) described in this work? What are the benefits of 'embedding' a mental health care worker in the ACHD...

This week we review a recent work from the team at Seattle Children's Hospital about obstetrical sonography and referral of fetuses with 'suboptimal imaging' for fetal echocardiography. Should all 'suboptimal imaging' cases be referred? How can fetal cardiologists parse out who needs a fetal cardiac scan and when? How does the fetal team in Seattle practically serve a geographic region exceeding 2...

This week we review a recent PHTS study on long-term outcomes following heart transplantation. Why do patients develop coronary vasculopathy and how commonly is it seen at long term follow-up? What factors are associated with better or worse long term outcomes? How do 'adverse childhood experiences' result in worse outcomes for patients? Why do young transplant patients have better long-term outco...

This week we review a recent study assessing the rate of hematochezia seen in children following neonatal congenital heart surgery, predominantly for aortic obstruction such as in HLHS. How often is this sign observed in this patient group and what percentage of these patients have actual necrotizing enterocolitis (NEC)? Are there any modifiable risk factors for NEC? How can these data help clinic...

This week we review a recent report of 4 patients with serious complications related to either perforation or external compression from the distal tines of the Alterra prestent when used for transcatheter pulmonary valve replacement. We speak with Dr. R. Allen Ligon, interventional cardiologist at Children's Healthcare of Atlanta/Emory University about a recent multicenter report of rare complicat...

This week we review a report from the teams at University College, Dublin and Texas Children’s Hospital about a collaborative approach to education in which two centers across the globe participate in a shared fellow learning conference. In this conference which is aimed at fellow education, topics are chosen and discussed with facilitated learning from faculty at both sites. What can be gained fo...

This week we review a recent review paper on newest innovations and literature on pacing in pediatric patients and learn a bit about such diverse pediatric pacing topics as: Use of the Medtronic Micra device in an off-label manner for epicardial pacing in small infants Novel, less invasive approaches to placing epicardial leads in small children The role of leadless pacing in the pediatric or CHD...

This week we step back in time 3 years ago to review an important cardiac MRI report on Fontan geometry and hemodynamics as measured by computational fluid dynamic analysis. How do factors like Fontan geometry or 'power loss' relate to quality of life for the Fontan young adult patient? How do these data inform imaging in the operating room during these palliations? We speak with the first author...

This week we review a work from the department of cardiology and department of cardiac surgery at Boston Children's Hospital on late hypertension in patients following coarctation repair. Late hypertension has been associated previously with late transverse aortic arch Z score but can this be predicted by the immediate postoperative transverse aortic arch Z score also? What factors account for lat...

This week we delve into the world of cardiovascular surgery and general cardiology when we review a recent report from UVA on the topic of feeding around the time of neonatal heart surgery. Does preoperative oral feeding improve the chances for 'tube-free' enteral feeds at discharge after heart surgery in small infants? Why might oral feedings improve the chances of discharge oral feedings? How sh...

This week we review a recent ACTION NETWORK project comparing outcomes of children with CHD who undergo VAD support in comparison to those children with VAD's who do not have CHD. How do morbidity and mortality rates compare between these two cohorts? Why might there be differences in outcomes between these two groups? How are heart failure and transplant cardiologists going to improve outcomes in...

In this week's replay episode from 2023, we speak with Associate Professor of Pediatrics at Mount Sinai, Dr. Jennifer Cohen about a recent large scale Fetal Heart Society project she conducted on the topic of fetal ccTGA and outcomes. What observations in fetal life are associated with worse clinical outcomes? Why is it valuable to perform serial fetal echocardiograms in this patient group? How co...

This week we delve into the world of cardiovascular surgery when we review a recent multicenter ("Ross Collaborative") study of long term outcomes of the Ross procedure in newborns and infants. How durable of a repair is this in this young age range? How does the neo-aortic root grow with time? Why might the neo-aorta not dilate in this age group as much as is reported in older patients following...

This week we review a recent report that asks the question, 'Do all infants who present with SVT require preventive anti-arrhythmic medical therapy?' Who might be a candidate for not using an anti-arrhythmia medication in infancy? What sort of parental education is needed to potentially not use medicine and how do patients not treated compare to those who were treated with anti-arrhythmics in rega...

This week we review a recent large scale, multicenter adult congenital heart study on outcomes of HLHS Fontan patients versus other single RV Fontan patients. How do the two groups compare in regards to thromboembolic risk, risk for arrhythmia or risk for death and heart transplantation? Why might there be differences between these single RV patient groups? How can these results inform management?...

This week to conclude 2024 we speak with noted investment expert Mr. Paul Merriman to discuss a few topics related to personal finance and investing. First we tackle the notion of having 'enough' to retire. Is there a magic value and how would one think about this? Why is an S&P 500 Index or Total US Stock Market Index a fine 'core' investment and how might one possibly  improve upon its perfo...

This week we replay episode #203 with Professor Michael Freed of Harvard University, who died this past week. In this episode from 2022 we review his seminal paper on prostaglandin for the treatment of infants with critical congenital heart disease from 1981 and then speak with Dr. Freed about his life, career, the development of PGE1 and more in this wide-ranging interview with this pediatric car...

This week we delve into preventive cardiology with noted world authority, Associate Professor of Pediatrics, Dr. Carissa M. Baker-Smith of Nemours Health.
