Bidirectional glenn surgery without palliative pulmonary artery banding in univentricular heart with unrestricted pulmonary flow. Retrospective multicenter experience.

Background: Although pulmonary artery banding (PAB) has been generally acknowledged as an initial palliative treatment for patients having single ventricle (SV) physiology and unrestrictive pulmonary blood flow (UPBF), it may result in unfavorable outcomes. Performing bidirectional Glenn (BDG) surgery without initial PAB in some selected cases may avoid the complications associated with PAB and reduce the number of operative procedures for these patients. This research aimed to assess the outcome of BDG surgery performed directly without doing initial PAB in patients with SV-UPBF.

Percutaneous closure of postoperative residual ventricular septal defects, including dehiscence of surgical patches.

Background: Percutaneous closure of residual ventricular septal defects (VSDs) after congenital heart surgery may provide a safer and more efficient alternative to redo surgery. This study aimed to evaluate the outcome of transcatheter closure of residual postoperative VSD.

Methods: This multicenter retrospective cohort study was conducted at the tertiary care institutions of King Faisal Specialist Hospital and King Abdulaziz University Hospital, Saudi Arabia, from March 2012 to March 2022.

Outcomes of bidirectional Glenn surgery done without prior cardiac catheterization.

Background: Cardiac catheterization is usually done routinely in patients with univentricular hearts before palliative Bidirectional Glenn (BDG) surgery. The objective of this study was to compare the outcomes of patients with physiological univentricular hearts and restrictive pulmonary flow that did not undergo routine cardiac catheterization before BDG with the patients that did have cardiac catheterization done. We retrospectively reviewed the data of all patients with single ventricle physiology and restrictive pulmonary blood flow who underwent BDG surgery from January 2016 till December 2020.

Neonatal congenital heart surgery: contemporary outcomes and risk profile.

Objective: Many studies still dispute the identification of independent risk factors that influence outcome after neonatal cardiac surgery. We present our study to announce the contemporary outcomes and risk profile of neonatal cardiac surgery at our institute.

Methods: We designed a retrospective study of neonatal patients who underwent surgery for congenital heart diseases between June 2011 and April 2020.

Outcome of ductus arteriosus stenting including vertical tubular and convoluted tortuous ducts with emphasis on technical considerations.

Background: Ductal stenting is the preferred method of securing adequate pulmonary blood flow in patients with duct-dependent pulmonary circulation. The main limitation in most centers is the difficult vertical tubular or convoluted ducts that represent real challenges to interventional pediatric cardiologists. We present our experience in patent ductus arteriosus (PDA) stenting with some technical tips to overcome difficulties, especially in stenting tortuous or long tubular ducts.

Cardiac Catheterization During Extracorporeal Membrane Oxygenation After Congenital Cardiac Surgery: A Multi-Center Retrospective Study.

Cardiac catheterization can affect clinical outcomes in patients on extracorporeal membrane oxygenation (ECMO) after congenital heart surgery; however, its effect in this group of patients remains unclear. This study aimed to evaluate the safety and outcome of cardiac catheterization in patients undergoing ECMO after congenital cardiac surgery and determine predictors that influence successful weaning. This retrospective cohort study included pediatric patients who underwent cardiac catheterization while on ECMO after congenital heart surgery in two cardiac centers between November 2012 and February 2020.
