Pediheart: Pediatric Cardiology Today

This week we review a recent large scale PHIS database study on pericardial effusion following congenital heart surgery. Which operations other than ASD are most highly associated with the development of an effusion? What might be some approaches both surgically and medically to reduce the chances of these developing or requiring intervention? What are the implications of a pericardial effusion after surgery? How many require readmission for this complication? Dr. Mario O'Connor, who is a congenital heart surgical research fellow at UT Austin, shares his insights into his recent publication. DOI: 10.1177/21501351251322876

This week we review a recent report on LV strain following the Ross operation. Can this sort of functional analysis help predict remodeling after aortic valve replacement? How can the type of Ross potentially affect heart function after the operation? Why might some parameters of LV strain improve but others not following surgery? Can preoperative strain measurements predict perioperative course? How does the addition of a Konno to a Ross change the outcomes of function? We speak with Chief of Cardiovascular Surgery at Primary Children's Hospital in Utah, Dr. S. Adil Husain and 3rd year integrated cardiac surgical resident Michal Schaffer of the University of Utah about these and other topics related to LV function following the Ross operation in children. ·         DOI: 10.1007/s00246-025-04124-9

This week we end 2025 with a Pediheart tradition - an episode on personal finance for medical professionals with noted authority on index investing and personal finance, Mr. Paul Merriman. Paul is a retired investment advisor who now has a popular podcast "Sound Investing" and website in which he offers advice on investing for 'do it yourself' investors. In this week's episode, the 5th of his visits to Pediheart, Mr. Merriman discusses 'factor investing' via index-like ETF's and funds. He also reviews who he believes might benefit from a financial advisor, what sort of advisor most should seek out and why he believes that many do not need one if they can 'stay the course'. Resources mentioned in today's podcast are below. Wishing all a happy and healthy new year in 2026. Paul's website:https://www.paulmerriman.com/#gsc.tab=0'Best In Class' ETF's:https://www.paulmerriman.com/Best-in-Class-ETF-Recommendations2025#gsc.tab=0Sound Investing 'Quilt Charts':https://irp.cdn-website.com/6b78c197/files/uploaded/(K)_Quilt_Charts_(1928-2024)_-_2024_Returns_(1).pdfDFA 'Turn Out The Noise':https://www.dimensional.com/filmAs a reminder, all of the information provided in this week's episode should be considered entertainment and all financial decisions should be vetted with professionals or knowledgeable and trusted friends/family. 

This week we go back in time 2 years to review a recent paper from 2023 about outcomes of cardiac transplantation in the adult congenital heart patient (ACHD). Little has been written on this topic until this very robust and large scale report. How do single ventricle ACHD patients fair at transplant and how do they compare to non-ACHD heart transplant recipients? Why might 1 and 3 year outcomes not be a 'fair' method of assessing outcomes in this very high risk patient group? How do HLHS patient outcomes compare with other single ventricles? Are there better ways to measure risk in this patient group and how might the data in this work inform risk stratification and management of failing Fontan patients in whom transplantation is being considered? These are amongst the questions posed this week to the week's expert, Dr Daphne Hsu who is Professor of Pediatrics at the Albert Einstein College of Medicine at The Children's Hospital at Montefiore.https://doi.org/10.1016/j.jacc.2023.06.037For those interested in learning more about Dr. Hsu, take a listen to episode #166 from June, 2021:https://www.spreaker.com/episode/pediheart-podcast-166-a-conversation-with-professor-daphne-hsu--45144274

This week we speak with noted congenital cardiologist Professor Krishna Kumar of the Amrita Institute in Cochin, India and discuss his recent work on inequities in congenital heart care in the world. Over 90% of patients with CHD do not have access to care in the globe today. What is the path forward to improve this sobering statistic? How can a World Health Assembly resolution practically help improve care in LMIC countries worldwide? Dr. Kumar shares his deep insights.This week we also briefly note the passing of the wonderful and caring pediatric cardiologist Dr. Sangeetha Viswanathan of Chennai, India who tragically died suddenly this week while attending the World Congress events in Hong Kong. Dr. Kumar's words regarding his friend, former fellow and colleague are read in remembrance of this wonderful and giving cardiologist whose loss will be deeply felt by her patients, family and friends. DOI: 10.1016/j.jacc.2025.07.070
