Surface Rendering of Cross-Sectional Imaging and Medical Illustration for Perinatal Planning in Conjoined Twins.

Introduction: Surface rendering of diagnostic imaging data can reveal hidden conditions with an almost life-like realism. However, early gestation images alone are often insufficient to accurately predict postnatal anatomy. Yet, time-sensitive decisions may have to be made before detailed imaging becomes possible.

Geospatial Distribution of Prenatally and Postnatally Diagnosed Congenital Heart Disease: Implications for Equitable Care from a Fetal Heart Society Research Collaborative Study.

Objective: To characterize patterns in the geospatial distribution of pre- and postnatally diagnosed congenital heart disease (CHD) across 6 surgical centers.

Study Design: A retrospective, multicenter case series from the Fetal Heart Society identified patients at 6 centers from 2012 through 2016 with prenatally (PrND) or postnatally (PoND) diagnosed hypoplastic left heart syndrome (HLHS) or d-transposition of the great arteries (TGA). Geospatial analysis for clustering was done by the average nearest neighbor (ANN) tool or optimized hot spot tool, depending on spatial unit and data type.

Variation in prenatal surveillance and management of anti-SSA/Ro autoantibody positive pregnancies.

Objective: To describe international surveillance and treatment strategies for managing anti-SSA/Ro autoantibody positive pregnancies.

Study Design: An electronic REDCap questionnaire was distributed to Fetal Heart Society and North American Fetal Therapy Network members which queried institution-based risk stratification, surveillance methods/frequency, conduction abnormality treatments, and postnatal anti-SSA/Ro pregnancy assessment.

Results: 101 responses from 59 centers (59% US, 17% international) were collected.

Prenatal Predictors for Pulmonary Balloon Valvuloplasty in the Newborn.

Pulmonary balloon valvuloplasty (PBV) is the treatment of choice for subjects with isolated pulmonary valve stenosis (IPS). The purpose of this study was to define fetal echocardiographic features associated with an inpatient PBV prior to newborn hospital discharge and characterize resource utilization of IPS fetuses among participating centers. Six center, retrospective case series of singleton fetuses identified between 2010 and 2020 with IPS.

Impact of Neonatal Intervention on Left Ventricular Performance in Ebstein's Anomaly and Tricuspid Valve Dysplasia.

Background: Severe neonatal Ebstein's anomaly (EA) and tricuspid valve dysplasia (TVD) are associated with high perinatal morbidity and mortality. The authors recently demonstrated left ventricular (LV) dysfunction and dyssynchrony to be prevalent in affected newborns and to contribute to poor outcomes. The aim of this study was to investigate the impact of patent ductus arteriosus (PDA) closure, spontaneous or surgical ligation, or right ventricular exclusion (Starnes procedure) on LV performance in neonatal EA and TVD.

Prospective Evaluation of High Titer Autoantibodies and Fetal Home Monitoring in the Detection of Atrioventricular Block Among Anti-SSA/Ro Pregnancies.

Objective: This prospective study of pregnant patients, Surveillance To Prevent AV Block Likely to Occur Quickly (STOP BLOQ), addresses the impact of anti-SSA/Ro titers and utility of ambulatory monitoring in the detection of fetal second-degree atrioventricular block (AVB).

Methods: Women with anti-SSA/Ro autoantibodies by commercial testing were stratified into high and low anti-52-kD and/or 60-kD SSA/Ro titers applying at-risk thresholds defined by previous evaluation of AVB pregnancies. The high-titer group performed fetal heart rate and rhythm monitoring (FHRM) thrice daily and weekly/biweekly echocardiography from 17-26 weeks.

The Resident Readiness Survey: A National Process for Program Directors to Provide Standardized Feedback to Medical Schools About Their Graduates.

The process for program directors (PDs) to provide feedback to medical schools about their graduates' readiness for postgraduate year 1 (PGY-1) training is burdensome and does not generate national benchmarking data. The Association of American Medical Colleges (AAMC) tested the feasibility of administering a standardized Resident Readiness Survey (RRS) to PDs nationally about their PGY-1 residents' preparedness for residency. In 2020 and 2021, the AAMC invited PDs via email to complete RRSs for their PGY-1s who graduated from participating schools; the AAMC provided schools with reports of identified RRS data for their graduates.

Public and Population Health in U.S. Medical Education: A Review of Guidance in Extraordinary Times.

Generations of medical educators have recommended including public and population health (PPH) content in the training of U.S. physicians.

Physicians' continuing medical education activities and satisfaction with their ability to stay current in medical information and practice: A cross-sectional study.

Background And Aims: Little is known about physicians' approaches to continuing medical education (CME) for continuing professional development despite the rapid evolution of CME offerings. We sought to identify the extent to which demographic, career, and experiential CME-activity variables were independently associated with physicians' satisfaction with their ability to stay current on medical information and practice.

Methods: Using the 2019 Association of American Medical Colleges' National Sample Survey of Physicians data, we ran multivariable logistic regression models examining demographic, career, and experiential (participation in 11 CME activities in the past year) variables for their associations with physicians' satisfaction (satisfied vs.

Amniotic Fluid microRNA in Severe Twin-Twin Transfusion Syndrome Cardiomyopathy-Identification of Differences and Predicting Demise.

Twin-twin transfusion syndrome (TTTS) is a rare but serious cause of fetal cardiomyopathy with poorly understood pathophysiology and challenging prognostication. This study sought a nonbiased, comprehensive assessment of amniotic fluid (AF) microRNAs from TTTS pregnancies and associations of these miRNAs with clinical characteristics. For the discovery cohort, AF from ten fetuses with severe TTTS cardiomyopathy were selected and compared to ten normal singleton AF.

Left Ventricular Dysfunction in Neonatal Ebstein's Anomaly and Tricuspid Valve Dysplasia.

Background: The mechanisms and prognostic importance of left ventricular (LV) dysfunction in neonatal Ebstein's anomaly (EA) and tricuspid valve dysplasia (TVD) are not well understood. The authors recently demonstrated reduced cardiac output and dyssynchrony to be common in fetal EA/TVD and therefore hypothesized that LV dysfunction may be associated with worse outcomes in neonatal EA/TVD.

Methods: A multicenter retrospective case-control study was conducted among neonatal patients with EA/TVD (n = 32) and a healthy control cohort (n = 17) encountered from 2004 to 2019.

Successful Treatment of Placental Chorangiomas by Ultrasound-Guided Percutaneous in utero Microcoil Embolization.

Placental chorangiomas can cause a high-output fetal state and increase neonatal morbidity and mortality. There is a paucity of data published describing the optimal treatment of these cases, and methods for occlusion to date include placement of vascular clips, bipolar cautery, injection of alcohol or surgical glue, interstitial laser, and microcoil embolization. We report 2 cases of prenatally diagnosed chorangiomas that caused a high-output fetal state and were successfully treated with microcoil embolization.

Consensus-Driven Priorities for Firearm Injury Education Among Medical Professionals.

Purpose: Firearm injury is a leading cause of morbidity and mortality in the United States. However, many medical professionals currently receive minimal or no education on firearm injury or its prevention. The authors sought to convene a diverse group of national experts in firearm injury epidemiology, injury prevention, and medical education to develop consensus on priorities to inform the creation of learning objectives and curricula for firearm injury education for medical professionals.

Discontinuation of the USMLE Step 2 Clinical Skills Examination: Studying the Past to Define the Future.

The United States Medical Licensing Examination (USMLE) Step 2 Clinical Skills (CS) was discontinued in January 2021, marking a significant milestone in assessment of clinical skills. In this commentary, the authors trace the history of the Step 2 CS exam-beginning with its early roots in the 1960s up to its discontinuation in 2021. In this new era, the medical education community is replete with opportunities for advancing methodology and content associated with clinical skills assessment.

Contemporary Outcomes in Tetralogy of Fallot With Absent Pulmonary Valve After Fetal Diagnosis.

Background Tetralogy of Fallot with absent pulmonary valve is associated with high mortality, but it remains difficult to predict outcomes prenatally. We aimed to identify risk factors for mortality in a large multicenter cohort. Methods and Results Fetal echocardiograms and clinical data from 19 centers over a 10-year period were collected.

Fetal Unguarded Mitral Valve Orifice, Aortic Atresia, and Severe Left Heart Enlargement.

Unguarded mitral valve orifice is a rare disease with only 7 described cases in the literature. We describe the first known case of unguarded mitral valve orifice with normal segmental cardiac anatomy, severe left ventricular dilatation and dysfunction, aortic atresia, and atrial flutter. ().

Impact of Socioeconomic Status, Race and Ethnicity, and Geography on Prenatal Detection of Hypoplastic Left Heart Syndrome and Transposition of the Great Arteries.

Background: Prenatal detection (PND) has benefits for infants with hypoplastic left heart syndrome (HLHS) and transposition of the great arteries (TGA), but associations between sociodemographic and geographic factors with PND have not been sufficiently explored. This study evaluated whether socioeconomic quartile (SEQ), public insurance, race and ethnicity, rural residence, and distance of residence (distance and driving time from a cardiac surgical center) are associated with the PND or timing of PND, with a secondary aim to analyze differences between the United States and Canada.

Methods: In this retrospective cohort study, fetuses and infants <2 months of age with HLHS or TGA admitted between 2012 and 2016 to participating Fetal Heart Society Research Collaborative institutions in the United States and Canada were included.

Extracardiac Doppler indices predict perinatal mortality in fetuses with Ebstein anomaly and tricuspid valve dysplasia.

Objectives: Ebstein anomaly and tricuspid valve dysplasia (EA/TVD) carry high perinatal mortality. Past studies have focused on cardiac predictors of mortality; we sought to describe the fetal echo (FE) extracardiac Dopplers in this cohort and determine their association with perinatal mortality.

Method: Fetuses with EA/TVD at 23 centers from 2005-2011 were included for retrospective study.

Risk Factors for Mortality and Circulatory Outcome Among Neonates Prenatally Diagnosed With Ebstein Anomaly or Tricuspid Valve Dysplasia: A Multicenter Study.

Background In a recent multicenter study of perinatal outcome in fetuses with Ebstein anomaly or tricuspid valve dysplasia, we found that one third of live-born patients died before hospital discharge. We sought to further describe postnatal management strategies and to define risk factors for neonatal mortality and circulatory outcome at discharge. Methods and Results This 23-center, retrospective study from 2005 to 2011 included 243 fetuses with Ebstein anomaly or tricuspid valve dysplasia.
