Pediheart Podcast # 96: Interhospital Collaboration Improves Congenital Heart Surgical Outcomes Dec 06, 2019

Show notes

This week we review a recent report of the PC4 group assessing the impact of inter hospital open communication and collaboration on surgical outcomes. In what manner did participation in this collaborative CICU registry improve outcomes for different hospital surgical outcomes? Why was the improvement not homogeneous between centers? How long did it take for the impact of collaboration to positively improve outcomes? We discuss these and other questions with first author Dr. Michael Gaies, Associate Professor of Pediatrics - University of Michigan. doi: 10.1016/j.jacc.2019.09.04

Pediheart Podcast #95: A Novel Device To Assess Aortic Valves Prior To And After Repair Nov 29, 2019

Show notes

This week the topic is cardiovascular surgery and we speak with Dr. Ignacio Berra of Buenos Aires Argentina about a recent work he co-authored with the surgical bioengineering team at Boston Children's Hospital regarding a newly developed tool to assess the aortic valve. Can this device safely allow for visualization of the valve under the usual aortic diastolic pressures to aid in anatomical assessment and post-repair assessment? What are the technical hurdles of using this device? Is it ready for use in humans? We discuss these and other questions with Dr. Berra this week. doi: 10.1016/j.jtcvs.2018.07.113

Pediheart Podcast # 94: Use Of An "Echo Pause" For Postoperative Transthoracic Echocardiographic Surveillance Nov 22, 2019

Show notes

This week we review a work that aimed to improve the thoughtfulness of echocardiography usage in the postoperative period after congenital heart surgery. Dr. Kelly Cox and colleagues report on the use of a 'checklist' type 'pause' aimed at making certain that the ordering team in the CVICU are making an informed decision regarding the need for a new echocardiogram. How often should postoperative studies be performed? How often did the 'fluid check' actually show fluid? These are amongst the many questions we post to Professor Cox who presently works at Lurie Children's Hospital - Northwestern University. doi: 10.1111/echo.1450

Pediheart Podcast # 93: Neurodevelopmental Outcomes In Children Supported With ECMO For Cardiac Indications Nov 15, 2019

Show notes

ECMO use in the pediatric cardiac patient can be lifesaving but the long term effects are still not well known. This week we explore the neurodevelopmental outcomes in a cohort of patients from Boston Children's Hospital who underwent ECMO support following cardiac surgery and explore factors associated with their neurodevelopmental outcomes. How do these patients fare in comparison to non-ECMO pediatric cardiac surgical patients? Are there modifiable factors that may improve outcomes? We explore these issues with Dr. Ravi Thiagarajan, Professor of Pediatrics - Harvard University and Director of Cardiac Critical Care at Boston Children's Hospital this week. doi: 10.1007/s00246-019-02115-1

Pediheart Podcast # 92: Factors Associated With Shunt Failure In The Single Ventricle Patient Nov 08, 2019

Show notes

This week we speak with cardiovascular surgeon Dr. Johann Brink about a recent work he co-authored from the Royal Children's Hospital in Melbourne, Australia about the team's experience with shunt malfunctions. Are there factors that are associated with shunt failure in this sometimes fragile patient group? Survival to Fontan in most series is roughly 70% - what, if anything, can 'move the needle' to higher levels of survival in this patient population? Dr. Brink offers some interesting and important insights this week. doi: 10.1016/j.jtcvs.2019.03.126.

Pediheart Podcast # 91: Pre-Participation Sports Evaluation - ECG vs. 14 Point AHA Evaluation Nov 01, 2019

Show notes

This week's episode is co-branded with the SADS Foundation and we review a recent work by the team at U. of Washington on a comparison between the ECG and the AHA 14 point evaluation recommendation for the identification of cardiac diseases that may predispose to sudden death amongst high school athletes. We speak with Dr. Jonathan Drezner of U. of Washington about this important work and he offers many insights into the pluses and minuses of both the history and physical approach as well as the ECG.

Pediheart Podcast # 90: Early Outcomes In Heart Transplantation In The Low Risk Pediatric Recipient And Steroid Avoidance Oct 25, 2019

Show notes

This week we 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 immunological risk' subset of patients undergoing heart transplantation? We speak with the first author of this work, Professor of Pediatrics, Dr. Jacqueline Lamour of The Albert Einstein College of Medicine. Dr. Lamour provides deep insights this week! doi: 10.1016/j.healun.2019.06.006

Pediheart Podcast # 89: Use of Personalized Computational Models To Predict Ventricular Arrhythmia in Tetralogy of Fallot Oct 18, 2019

Show notes

Identification of the tetralogy of Fallot patient at risk for ventricular arrhythmias might be the 'holy grail' of ACHD and still today the best predictors are unclear. This week we review a novel approach to this problem - the development of personalized computational models to effectively perform 'virtual EP studies' and predict reentrant ventricular arrhythmia risk in repaired TOF patients. We speak with Dr. Mark Cartoski, Assistant Professor of Pediatrics at Nemours duPont Children's Hospital about a recent work he co-authored on this topic. Can VT be predicted on a computer rather than with catheters in the heart?

Pediheart Podcast #88: Role Of MRI Fusion With Fluoroscopy For Congenital Heart Interventional Catheterization Oct 11, 2019

Show notes

This week we review a recent work from the team at Children's National in DC and the NIH on the use of 3D fusion of MRI images with fluoroscopy to help inform interventional procedures. Does this form of "XFM" fusion improve outcomes and reduce radiation or contrast usage? Are there procedures in which this form of imaging might be best applied? We review these and other questions with the first author of this work, Dr. Elena Amin of UCSF. doi: 10.1002/ccd.28324

Pediheart Podcast # 87: Parental Psychological Reactions To Fetal vs. Postnatal Diagnosis of CHD Oct 04, 2019

Show notes

This week we review a recent small work on the impact of fetal diagnosis of congenital heart disease on the psychological well being of families. Does the fetal prenatal diagnosis and counseling result in less stress in comparison to the families of those diagnosed in the postnatal period? We review this and other questions regarding prenatal counseling with Dr. Miwa Geiger - Director of Fetal Cardiology at Mount Sinai Kravis Children's Hospital and Ms. Michele Cafone, MSN, RN, CPNP - Clinical Nurse Coordinator of The Fetal Heart Program at Sinai. Two top experts on counseling to address some important and provocative questions. doi: 10.1017/S1047951119001781
