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 coronary stent implantation in children and young infants following surgical repair of congenital heart disease.

Background: Coronary artery stent implantation (CSI) in the pediatric population is rare. Only a few reports were published on managing postoperative coronary artery obstruction using coronary stents following surgical repair of congenital heart diseases (CHD). This study aimed to analyze the feasibility, indications, procedural technique, risk factors, and short-term outcomes of CSI after pediatric cardiac surgery.

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.

Transcatheter closure of main pulmonary artery pseudoaneurysm using atrial septal occluder device in an infant.

We present a case of percutaneous closure of main pulmonary artery pseudoaneurysm using an atrial septal occluder device in a seven-month-old infant. The infant had tetralogy of Fallot repair followed by transcatheter left pulmonary artery stenting. The occlusion of the wide neck of the pseudoaneurysm was performed successfully using the atrial septal occluder with no detected complications in his six-month follow-up post-catheterisation.

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.

Background: Cardiac catheterization after congenital heart surgery may play an important role in the diagnosis and management of patients with a complicated or unusual post-operative course. The main objective of this study was to evaluate the safety, efficacy, and outcome of cardiac catheterization performed in the early post-operative period following congenital heart surgery. All patients who underwent cardiac catheterization after congenital heart surgery during the same admission of cardiac surgery from November 2015 to May 2018 were included in the study.

Novel approach for Recanalization and Limb Saving Following Acute Thrombosis of Upper Limb Arteries in Two Neonates After Congenital Heart Surgery.

Neonates with congenital heart disease are at a high risk of vascular thrombosis. Thrombosis may occur due to vascular injury, increased blood viscosity secondary to polycythemia associated with congenital cyanotic heart diseases, or stasis of blood flow associated with low cardiac output (Schmidt B & Andrew M., Pediatrics 1995; 96: 939-943.

Bovine jugular vein valved xenograft for extracardiac total cavo-pulmonary connection: The risk of thrombosis and the potential liver protection effect.

Background: Currently, non-valved conduits are preferred for extracardiac total cavo-pulmonary connection (TCPC). However, previous work has failed to provide objective data comparing the postoperative outcome between non-valved TCPCs and bovine jugular vein valved xenograft (BJV) TCPCs. Hence, the objective of this study is to compare the postoperative outcomes in extracardiac TCPC patients who received BJV vs synthetic non-valved conduits and evaluate the effect of BJV on liver fibrosis.

Gastrointestinal presentation of COVID-19 in a pediatric heart transplant recipient.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated coronavirus disease 2019 (COVID-19) most commonly causes a mild respiratory illness; however, there are wide ranges of presenting symptoms and disease severity. It has a mortality rate around 7%.

Case Presentation: We present a case of a 9-year-old female patient with hypoplastic left heart syndrome status post heart transplantation at age of 7 days.

Rare combination of bilateral divided atrial chambers and pulmonary vein stenosis with review of the literature.

The term cor triatriatum is used to describe a fibromuscular partition that divides an atrium into two compartments. It was first used by Borst in 1905, although the lesion had been described before by Church in 1868. Both described divided left atrial chamber (also referred to as cor triatriatum sinister).

Stent protrusion in palliative congenital heart disease interventions: does it cause any harm?

Background: Protrusion of the patent ductus arteriosus (PDA) stent can occur into the lumen of the main pulmonary artery (MPA) branch, the aorta, or both. This protrusion can vary from trivial to major, causing potential obstruction to the vessel lumen, which may cause flow obstruction or risk of thromboses. As far as we know, no one has followed these patients with protruding stents to see whether they do pose a risk of obstruction or thromboses.

Comparative outcome of bidirectional Glenn shunt in patients with pulmonary vascular resistance > or = 3.5 woods units versus < 3.5 woods units.

Moderate to severe pulmonary hypertension is considered to be an absolute contraindication to the performance of bidirectional Glenn (BDG) shunting. However, BDG shunting has been performed in young children with pulmonary hypertension associated with unrestricted pulmonary blood flow. In this study, the medical records of patients who underwent BDG starting from October 2000 to March 2004 were reviewed.
