Association Between Remote Monitoring And Interstage Morbidity And Mortality In Single Ventricle Patients Across Socioeconomic Groups, Bianca Cherestal

Research Days

Background: Despite improvements in outcomes over time, morbidity and mortality for infants with single ventricle (SV) heart disease remains high. Among other risk factors for mortality, infants of low socioeconomic status (SES) are known to be particularly vulnerable following stage 1 palliation.

Objectives/Goal: We sought to determine whether use of a novel remote monitoring program, CHAMP (Cardiac High Acuity Monitoring Program), mitigates differences in outcomes by SES for infants with SV during the interstage period.

Methods/Design: Using the CHAMP database, we identified 610 infants across 11 institutions enrolled in the program between 2014–2021. All enrolled patients’ families were provided with …

Therapeutic Plasma Exchange To Alleviate Ventricular Tachycardia After Diphenhydramine Ingestion, Kaushal Dosani, Lejla Music Aplenc, Stephen Pfeiffer

Research Days

Background: The Covid-19 pandemic has adversely affected the mental health of children causing an increased incidence of suicide attempts. Diphenhydramine is a common household medication and is frequently ingested by children. Toxic doses of diphenhydramine can affect the cardiovascular and central nervous system. In the heart, diphenhydramine blocks fast sodium channels and potassium channels which can result in conduction abnormalities including sinus tachycardia, widening of QRS duration, ventricular tachycardia and torsades de pointes. Massive ingestion can cause severe cardiovascular collapse which may require ECMO support

Objectives/Goal: To describe a novel method of clearing highly protein-bound diphenhydramine molecules from circulation after …

Safety, Timing And Outcomes Of Early Postoperative Cardiac Catheterization Following Congenital Heart Surgery, Karoline Krzywda

Research Days

Watch recording of live presentation

Background: Early postoperative ( < 6weeks) cardiac catheterization (EPOCC) has been considered high risk and often delayed. Recently, the safety of EPOCC has been demonstrated. The optimal timing of catheterization and its outcomes in struggling postoperative patients remains uncertain.

Objective: To describe EPOCC in our center and its impact on length of stay (LOS), number of mechanical ventilation days, number of ECMO days, and catheter-based interventions.

Methods: This is a retrospective cohort study of patients who underwent cardiac surgery between 01/01/2010 and 12/31/2019 and EPOCC within 30 days after surgery. Cohorts were early EPOCC (≤72 hr) vs late EPOCC ( >72 hr). Data on timing, indication, and complications of EPOCC; days of mechanical ventilation and ECMO; and CICU/total hospital LOS were collected. Data was analyzed using chi-square and Student’s t-test, …

Ekg Technology: It Is Time For A Change!, Megan Carroll

Research Days

Watch recording of live presentation

Background: Technology for obtaining pediatric EKGs has not changed in over 70 years. Current guidelines recommend a 12-lead EKG, which takes approximately 7 minutes to complete. Newer adult technology utilizes between 1-6 leads for EKG analysis. There has not been a study in pediatrics to assess the minimum number of leads required to attain diagnostic accuracy.

Objectives/Goal: To determine the appropriate number of leads needed to read pediatric EKGs safely and accurately.

Methods/Design: This is a single center systematic review that included randomly selected EKGs from our hospital database (2017-2020) read by two independent pediatric …

Neonatal Hypoxia Due To Pulmonary Artery Thrombus, Bianca Cherestal

Research Days

Background: Pulmonary artery thrombus is rare and should be considered in neonates with refractory hypoxia.

Case: Preterm female neonate had persistent hypoxia after birth despite intubation, high-frequency oscillatory ventilation (FiO2 100%), and inhaled nitric oxide. Delivery was via c-section at 33 weeks 4 days for new onset hydrops and poor biophysical profile. Echocardiogram revealed echo brightness in the lumen of the left pulmonary artery (LPA) with no color flow (figure 1a), concerning for occlusive thrombus. Chest CT angiogram confirmed the diagnosis (figure 1b, c). Hematology was consulted and recommended systemic thrombolysis (tissue plasminogen activator, tPA) with concomitant anticoagulation (Bivalirudin). Imaging …

Constrictive Pericarditis After Repair Of A Ruptured Sinus Of Valsalva, Sarah Studyvin, Laura Kuzava

Research Days

Background: Constrictive pericarditis is an uncommon complication of cardiac surgery. We report a patient who developed constrictive pericarditis after ruptured sinus of Valsalva (RSOV) repair.

Methods: A 23-year-old male presented with exertional dyspnea one year after RSOV repair. TTE showed a small, circumferential effusion with thickened pericardium, ventricular septal bounce, left atrial enlargement, diastolic hepatic flow reversal, and trivial mitral regurgitation without stenosis. He underwent cardiac catheterization, which revealed elevated filling pressures (RVEDP 16 mmHg, LVEDP 18 mmHg), RVEDP/RVSP ratio < 0.5, and a low cardiac index (1.65 L/min/m2). Cardiac MRI confirmed pericardial thickening with paradoxic septal motion, dilated pulmonary veins and retrograde flow in the SVC.

Results: Pericardiectomy of thickened and adherent pericardium was performed. The central venous pressure decreased from 23 to 7 mmHg and …

Online Echocardiography Modules For Pediatric Cardiology Fellows, Sarah Studyvin, Doaa Aly, Tyler Johnson, Laura Kuzava, Alison Samrany, Nitin Madan, Sanket Shah

Research Days

Background: Adequate echocardiographic (echo) education is integral to successful cardiology training. Online education is proven to be effective in other specialties, but pediatric echo training data are lacking.

Objectives/Goal: Our aim was to design and assess the role of a novel online module-based curriculum to enhance pediatric cardiology fellows’ echo education.

Methods/Design: Four interactive modules, focused on principles and interpretation of a normal echo, were delivered to fellows. Content included high quality 2D and 3D echo clips as well as interactive quizzes and could be accessed from a phone, tablet, or computer. All fellows completed pre- and post-tests, validated by …

Pediatric Pulmonary Artery Aneurysms Causing Pulmonary Hemorrhage: A Case Of Transcatheter Intervention While On Va Ecmo Support, Igor Areinamo

Research Days

Background: The incidence of pulmonary artery aneurysm (PAA) in children remains unknown. There are few reports of a transcutaneous interventional approach to address this type of pathology. Management of PAAs while on VA ECMO has not been described in pediatrics.

Objectives/Goal:

Methods/Design:

Case: 9-year-old previously healthy male presented with MRSA associated ARDS and sepsis requiring urgent VA ECMO cannulation. Chest CT done on ECMO day 22 showed development of right sided PAAs. Patient had an episode of significant pulmonary hemorrhage. Angiogram demonstrated two fusiform right PAAs, one of which had ruptured and was bleeding into the lung parenchyma. Patient had …
