Repeat Repair After Translocation of an Anomalous Left Coronary Artery.

We repaired a left anomalous aortic origin of coronary artery using coronary ostium translocation/reimplantation. Repeat repair was required due to suboptimal flow pattern in postoperative transesophageal echocardiography, which was confirmed with coronary angiography. We emphasize the importance of early recognition, diagnosis, and intervention to deal with a problem with the coronary repair.

Morphology, Clinical Associations, and Pathologic Follow-up of Quadricuspid Aortic Valves in Children.

While quadricuspid morphology is commonly observed in truncal valves, quadricuspid aortic valves (QAV) are rare and their natural history is not well described. This retrospective study of 37 patients describes the diagnostic associations and morphologic variability of QAVs in children (median age at diagnosis 4.3 y IQR 0-12 y).

Trends in Delayed Diagnosis of Critical Congenital Heart Defects in an Era of Enhanced Screening, 2004-2018.

Objective: To describe trends in delayed diagnosis of critical congenital heart defects (CCHDs) with prenatal and postnatal screening advances.

Study Design: We evaluated a retrospective cohort of live births with CCHD delivered between 2004 and 2018 from a statewide, population-based birth defects surveillance system in Massachusetts. Demographic information were obtained from vital records.

Socioeconomic and Racial and/or Ethnic Disparities in Multisystem Inflammatory Syndrome.

Objectives: To characterize the socioeconomic and racial and/or ethnic disparities impacting the diagnosis and outcomes of multisystem inflammatory syndrome in children (MIS-C).

Methods: This multicenter retrospective case-control study was conducted at 3 academic centers from January 1 to September 1, 2020. Children with MIS-C were compared with 5 control groups: children with coronavirus disease 2019, children evaluated for MIS-C who did not meet case patient criteria, children hospitalized with febrile illness, children with Kawasaki disease, and children in Massachusetts based on US census data.

Novice Physician Ultrasound Evaluation of Pediatric Tricuspid Regurgitant Jet Velocity.

Introduction: Pulmonary hypertension, associated with high mortality in pediatric patients, is traditionally screened for by trained professionals by measuring a tricuspid regurgitant jet velocity (TRJV). Our objective was to test the feasibility of novice physician sonographers (NPS) to perform echocardiograms of adequate quality to exclude pathology (defined as TRJV > 2.5 meters per second).

Delayed diagnosis of critical congenital heart defects: trends and associated factors.

Objective: We aimed to examine trends in timing of diagnosis of critical congenital heart defects (CCHDs) and factors associated with delayed diagnosis (diagnosis after discharge home following delivery).

Methods: We examined a population-based retrospective cohort of CCHD cases among live births identified through the Massachusetts Birth Defects Monitoring Program. Congenital heart defects were considered critical if the infant received corrective surgery, interventional catheterization, palliative care, or died as a result of the defect within 12 months of birth.

Neonatal closure of a large coronary-cameral fistula in a case of single coronary artery: the utility of intraoperative angiography.

Isolated coronary artery fistula in the newborn is a very rare congenital anomaly. When symptomatic, treatment options include surgical management with ligation and/or patch closure or transcatheter coil embolization. We describe the case of a newborn with symptomatic left coronary-right ventricular fistula, which was managed operatively with off-pump ligation and on-table angiogram for confirmation of fistula obliteration and normal distribution of flow in the coronary artery.
