Hepatic Fibrosis Risk Factors in Extracardiac-Fontan Patients: Observations From a Single Center.

We reviewed our experience with transvenous liver biopsy-derived hepatic fibrosis scores and possible associated risk factors in those postextracardiac Fontan patients. We identified extracardiac-Fontan patients with postoperative durations <20 years who underwent cardiac catheterizations with transvenous hepatic biopsies between April 2012 and July 2022. If a patient underwent two liver biopsies, we averaged the two total fibrosis scores and concurrent time, pressure, and oxygen saturation data.

Isolated Vascular Rings Are Common Cardiovascular Malformations.

Objective: We investigated the prevalence of isolated vascular rings in the general population of Southern Nevada.

Methods: We identified those prenatally and postnatally diagnosed with an isolated vascular ring between January 2014 and December 2021. We included only those with vascular or ligamentous structures completely encircling the trachea and esophagus.

Prenatal diagnosis of hypoplastic aortic arch without intracardiac malformations: The nevada experience.

Objective: We reviewed our center's experience with neonatal and infant hypoplastic aortic arch, unassociated with intracardiac malformations, and investigated changes in prenatal detection rates over time for those requiring therapeutic procedures.

Methods: We identified all prenatal diagnoses of hypoplastic aortic arch with situs solitus, unassociated with intracardiac malformations, made in Nevada between May 2017 and April 2022. In addition, we identified all those 0-180 days old, with prenatal care, that underwent a surgical or interventional cardiac catheterization aortic arch procedure, whether prenatally or postnatally diagnosed.

Isolated Balanced Complete Atrioventricular Septal Defects: Prenatal Detection and Outcome in Nevada.

We analyzed patients with isolated, balanced complete atrioventricular septal defects. We identified 71 patients born in Nevada, between January 2008 and December 2020. We also analyzed prenatal detection rates.

Complex neonatal congenital heart surgery in Nevada.

Objective: We reviewed our center's surgical mortality rates for those who underwent a Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) category 4 or 5 neonatal cardiovascular surgery.

Methods: We identified all patients who underwent a STAT category 4 or 5 neonatal index cardiovascular surgical procedure between July 2015 and July 2021.

Results: We identified 239 patients.
