Clinical implication of intraoperative ventricular-arterial coupling in pediatric patients undergoing ventricular septal defects repair: A retrospective cohort study.

Background: Ventricular-arterial coupling is the ratio of arterial elastance to ventricular end-systolic elastance.

Aims: The objective of this study was to determine the clinical implication of intraoperative ventricular-arterial coupling derived from the pressure-area relationship using transesophageal echocardiography.

Methods: This retrospective study reviewed the medical records of 72 pediatric patients with ventricular septal defects who underwent corrective surgery with cardiopulmonary bypass.

Use of a High-Flow Nasal Cannula in a Child With a Functional Single Ventricle and Difficult Airway.

Inducing anesthesia and securing the airway without disrupting the patient's hemodynamic state are challenging in pediatric patients with a functional single ventricle (FSV). Here, the authors report effective use of a high-flow nasal cannula (HFNC) as a tool in providing oxygen supplementation for airway management in pediatric FSV patients with a history of a difficult airway. A female patient, aged 5 years 7 months, was admitted for extracardiac conduit Fontan procedure.

Pretransplant increases in left ventricular volume and mass are associated with QT prolongation during pediatric liver transplantation.

Structural alterations in the cirrhotic heart may contribute to electromechanical abnormalities, represented by QT prolongation. The aim of this study was to investigate the changes in QTc according to the operative stage during pediatric LT and to identify which baseline echocardiographic parameters were associated with intraoperative QTc prolongation. Data were evaluated from 39 children undergoing LT for chronic liver disease (median age 9 months).
