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

Management of Ebstein Anomaly in the Current Era: The Story of One Fetus and the Collaboration of Many-A Case Report

Collaborative multicenter research has significantly increased our understanding of fetal Ebstein anomaly, delineating risk factors for adverse outcomes as well as predictors of postnatal management. These data are incorporated into prenatal care and therapeutic strategies and inform family counseling and delivery planning to optimize care. This report details the translation of findings from multicenter studies into multidisciplinary prenatal care for a fetus with Ebstein anomaly, supraventricular tachycardia, and a circular shunt, including transplacental therapy to control arrhythmias and achieve ductal constriction, informed and coordinated delivery room management, and planned univentricular surgical palliation.

Top 100 Most Cited Papers on Multimodality Imaging for Complex Congenital Heart Disease. A Bibliometric Analysis

Complex congenital heart disease (CCHD) is a group of heart defects present at birth. Some imaging methods can support the diagnosis of these pathologies, such as echocardiography, computed tomography, and magnetic resonance imaging. This study aimed to perform a bibliometric analysis of the top 100 articles cited on CCHD. Articles from 2013 to 2023 found in Scopus were scanned using 15 CCHD topics titles crossed with echocardiography, computed tomography, and magnetic resonance imaging. Duplicated manuscripts were eliminated using Microsoft Excel software, and the publications were ranked according to their citation count. This study selected and analyzed the top 100 most cited English-language papers. The top 100 most cited publications accumulated 16,563 citations. The manuscript with the most citations obtained 1086, representing 6.55% of the total citations. The year 2014 had the highest number of publications, with 27 papers. The first authors had affiliations from 44 countries; the United States was the country that contributed the most, with 54 manuscripts. Boston Children's Hospital was the institution that provided more articles to the top 100. Finally, the Ebstein anomaly was the topic with the highest number of citations. This study identified the 100 most cited on CCHD, and the results obtained can provide practical guidance to clinicians and researchers to familiarize themselves with the most influential publications in this field.

The Association of Pulmonary Flow Characteristics With Cardiac Function in Tricuspid Valve Malformation Fetuses: Study With Two-Dimensional Speckle Tracking Echocardiography

OBJECTIVES

To explore the relationship between cardiac function and pulmonary flow characteristics in tricuspid valve malformation (TVM) fetuses by conventional and speckle tracking echocardiography.

METHODS

Eighty-eight TVM fetuses were retrospectively included and compared with 80 normal controls. TVM fetuses in each trimester were divided into two subgroups according to pulmonary flow characteristics: those with normal pulmonary flow (TVM-N) and those with reduced or absent pulmonary flow (TVM-R/A). Cardiac measurements, Celermajer index, and Simpson-Andrews-Sharland (SAS) score were obtained. Speckle tracking echocardiography was used to compute ventricular deformation parameters.

RESULTS

TVM fetuses demonstrated significantly lower global longitudinal strain (GLS) and strain rate for both ventricles than controls (all P < .05). When compared with TVM-N, left ventricular (LV) ejection fraction, LV fractional area change, right ventricular (RV) fractional area change, LVGLS, and RVGLS were significantly reduced (all P < .05), while the RV diameter Z-score, RV/LV diameter, SAS score, and Celermajer index were obviously increased in TVM-R/A in both trimesters (all P < .05). Both LVGLS and RVGLS correlated with cardiothoracic circumference ratio, RV diameter Z-score, RV/LV diameter, Celermajer index, and SAS score (all P < .01). There was a slow decline for LVGLS and RVGLS in TVM-N fetuses throughout the gestation. Conversely, these two parameters worsened rapidly in TVM-R/A group.

CONCLUSIONS

TVM fetuses present biventricular dysfunction by deformation analysis in the second and third trimester of pregnancy. TVM fetuses with reduced or absent pulmonary flow exhibit significantly greater impairment and more rapid deterioration of cardiac function, which may contribute to poor outcomes.
