Pediheart: Pediatric Cardiology Today

This week we feature a collaboration episode between the Pediheart Podcast and the PedsCrit Podcast in which pediatric critical care experts Drs. Alice Shanklin of Northwell Medical Center and Dr. Zac Hodges of UT Southwestern discuss the evaluation and management of heart block in children. What should the clinician be thinking when encountering a previously healthy child with heart block? When is pacing indicated and how should it be performed? Who is a candidate for transvenous or transcutaneous pacing, who is not and why? Drs. Pass, Shanklin and Hodges review many aspects of this in an episode from the PedsCrit Podcast.

This week we review a recent work from the CT group at NY Presbyterian assessing the impact of phenylephrine during pediatric congenital CT scans to lower heart rate. Why is a lower heart rate better for CCT's? Should this agent be routinely employed for this indication during CT scans in children? Dr. Yosef Cohen, pediatrics resident at the Children's Hospital at Montefiore shares his insights from a recent work he co-authored.

In this replay episode from 2 years ago, we delve into the world of adult congenital heart disease to review the topic of liver disease in the Fontan patient and specifically, hepatocellular carcinoma (HCC). What is the prevalence of this disease in the Fontan single ventricle adult patient? How effective are scores like the MELD-XI or Fibrosis-4 Index at identification of HCC in the Fontan patient? How should the Fontan adult patient be surveilled for this form of cancer? What evidence is there that earlier identification of HCC is associated with better outcomes? What may prove to be the most important factor in protection of the liver in the Fontan patient? Dr. Yuli Kim, Director of the ACHD program at The University of Pennsylvania shares her deep insights this week into this important topic.

This week we review a recent Australian prospective assessment of aspirin resistance in children undergoing heart surgery. How common is this seen in this patient group and what are the reasons? What is the best test to perform to assess this and what tests may not be worthwile? Who deserves 'routine' testing for this possible problem? Cardiovascular surgeon Dr. Supreet Marathe of Queensland Children's Hospital in Brisbane, Australia shares the results of this recent publication.

This week we speak with Assistant Professor of Pediatrics at Harvard Medical School, Dr. Audrey Dionne about a recent work she co-authored on sinus node dysfunction following congenital heart surgery. How common was this encountered and how often were either temporary or permanent pacing needed? Are there certain surgeries that are more associated with the need for pacing after surgery? Why is this so common following heart surgery? Dr. Dionne shares her deep knowledge this week on this surprisingly common problem.
