Significant interobserver and interstudy variability occurs for left ventricular (LV) functional indices despite standardization of measurement techniques. Artificial intelligence models trained on adult echocardiograms are not likely to be applicable a pediatric population. We present EchoNet-Peds, video-based deep learning algorithm, which matches human expert performance LV segmentation ejection fraction (EF).
Abstract Background Congenital and acquired heart disease affects ∼1% of children globally, with right ventricular (RV) dysfunction being a common complex issue due to conditions like congenital (CHD), pulmonary hypertension (PH), prematurity. Accurate RV assessment is challenging its unique geometry, interventricular interactions, morphological variability in pediatric patients. Fractional area change (FAC), key echocardiographic measure, correlates strongly severity, aiding timely...
Atrioventricular nodal reentrant tachycardia (AVNRT) typically occurs in adolescents and adults with limited data regarding AVNRT young children.All patients who underwent electrophysiology study ablation between 2005 2012 were retrospectively studied. Patients stratified by age <10 years (young AVNRT) or ≥10 (older AVNRT). Young also compared to age-matched orthodromic (ORT).A total of 275 studies 272 evaluated including 38 (7.7 ± 1.5 years) 202 older (14.9 2.1 years). An atrial-His jump...
Kawasaki disease (KD) is the leading cause of acquired heart in children. The major challenge KD diagnosis that it shares clinical signs with other childhood febrile control (FC) subjects. We sought to determine if our algorithmic approach applied a Taiwan cohort.A single center (Chang Gung Memorial Hospital Taiwan) cohort patients suspected acute were prospectively enrolled by local specialists for analysis. Our previously single-center developed computer-based two-step algorithm was...
Background Although aortic dilation is common in tetralogy of Fallot (TOF), its progression and risk dissection are not well understood. The mechanism primarily attributed to increased flow utero; an alternative unequal septation the truncus arteriosus resulting a larger aorta inherently hypoplastic pulmonary artery (PA). If latter true, we hypothesize PA ratio TOF stable throughout gestation, sums great dimensions similar controls. Methods Results We performed single-center retrospective...
Abstract Introduction: Transcatheter pulmonary valve replacement serves as a successful alternative to surgical of right ventricle artery conduit. Guidelines for recommending transcatheter depend on MRI ventricular volumes, which have been correlated the echocardiographic measure annular tilt. We aim assess whether tilt can be clinically useful tool in acute and long-term periods after health. Methods: reviewed 70 patients who underwent at single institution. Echocardiographic measurements...
Introduction: Echocardiographic assessment of left ventricular (LV) systolic function by ejection fraction (EF) is crucial for diagnosis and monitoring in pediatric patients. EF requires manual tracing the LV but measurement reproducibility affected diverse phenotypes, image quality, operator skill. We sought to train a deep learning model (EchoNet-Peds) on pediatric-specific video dataset automatically segment estimate 5/6 Area Length (AL) using two common views, apical 4 chamber (A4C)...
Intraoperative imaging determines the integrity of surgical repairs. Transoesophageal echocardiography represents standard care for intraoperative in CHD. However, some conditions preclude its use, and epicardial is used alternatively. Minimal literature exists on impact versus transoesophageal echocardiography. We aimed to evaluate accuracy between two modalities hypothesised higher error rates echocardiography.We retrospectively reviewed all echocardiograms performed over 16 years compared...
ABSTRACT Background Aortic dilation in tetralogy of Fallot (TOF) is primarily attributed to increased aortic flow utero . An alternative hypothesis abnormal neural crest cell migration, with unequal septation the truncus arteriosus resulting a larger aorta and inherently hypoplastic pulmonary artery (PA). If so, we hypothesize PA ratio (Ao:PA) TOF stable throughout gestation, total sum dimensions great arteries similar controls. Methods We performed single-center retrospective study all...
Anomalous coronary artery origin is rare and can occur with myocardial bridging. We describe a 28-year-old patient symptomatic anomalous right arising from the left sinus of Valsalva concomitant bridging anterior descending artery. It was discovered that ran along free ventricular wall trabeculated myocardium composing bridge. To address this, trabecular sinuses were unroofed, resulting edge sutured back to interventricular septum.
Introduction: Neonates with dextro-transposition of the great arteries (d-TGA) require adequate mixing at atrial level. If not present, these infants experience severe cyanosis, necessitating an urgent balloon septostomy (BAS). Multiple studies have identified various fetal echocardiography (FE) findings as risk factors for postnatal BAS. Anecdotally, predictive value remains poor in clinical use. Hypothesis: We aimed to determine relationship between inter-rater reliability (IRR) FE BAS...
Abstract Background No guidelines exist for inpatient postoperative transthoracic echocardiographic (TTE) surveillance in congenital heart disease. We prospectively evaluated indications TTEs patients with disease to identify areas improve upon (Phase 1) and then assessed the impact of a simple pilot intervention 2). Methods included RACHS‐1 (Risk Adjustment Congenital Heart Surgery) scores 2 3 keep cohort homogenous. During Phase 1, we collected data which there were no new findings...
ABSTRACT Kawasaki disease (KD) is the leading cause of acquired heart in children. A key objective research KD to reduce risk long-term cardiovascular sequelae by expediting timely diagnosis. The major challenge diagnosis that it shares clinical signs with other childhood febrile illnesses. Our previously single-center developed computer-based two-step algorithm was further tested a five-center validation US. This first blinded multi-center trial validated our approach, sufficient...
