Percutaneous Balloon-Expandable Stent Implantation to Treat Transverse Aortic Arch Obstruction: Medium- to Long-Term Outcomes of a Retrospective Multicenter Study.

Background: Transverse aortic arch obstruction is a challenging lesion for which stent implantation provides a potentially important alternate therapy. The objectives were to evaluate the technical, procedural, and medium-to-long-term clinical outcomes of percutaneous stent implantation of transverse aortic arch obstruction.

Methods: This is a retrospective, multicenter study of transverse aortic arch stent implantation.

Utility of Follow-Up Echocardiograms in Uncomplicated PDA Device Closures Performed During Infancy.

Introduction: Guidelines recommend lifelong follow-up with transthoracic echocardiograms (TTE) for patients who had a patent ductus arteriosus (PDA) device closure via catheterization. The goal of this study was to determine the utility of follow-up TTE in patients who underwent an uncomplicated PDA device closure during infancy.

Methods: Chart review was performed on patients who had a PDA closure at not more than 1 year of age between January 1, 2002 and June 1, 2020.

Utility of Follow-Up Echocardiograms in Uncomplicated PDA Device Closures Performed After Infancy.

Introduction: Guidelines recommend lifelong follow-up with transthoracic echocardiograms (TTE) for patients who had a patent ductus arteriosus (PDA) device closure via catheterization. The goal of this study was to determine the utility of follow-up TTE in patients who underwent an uncomplicated PDA device closure after infancy.

Methods: Chart review was performed on patients who had a PDA closure ≥ 1 year of age between 1/1/2002 and 6/1/2020.

Incidence of and Risk Factors for Aortic Arch Interventions After the Comprehensive Stage II Procedure for Hypoplastic Left Heart Syndrome.

Minimal data exist about the incidence and risk factors for arch intervention after comprehensive stage II (CSII). Goal of this study was to document incidence of arch interventions after CSII and determine if any differences existed between those who underwent an arch intervention (aiCSII) versus those did not have an intervention. Single-center retrospective chart review of all hypoplastic left heart syndrome patients who underwent a CSII between 6/1/2005 and 2/1/2020 was performed.

Implantable pulmonary artery pressure monitoring device in patients with palliated congenital heart disease: Technical considerations and procedural outcomes.

Objective: We describe the technical considerations of transcatheter implantation of the CardioMEMS™ HF System (Abbott, Abbott Park, IL) in adult patients with complex palliated congenital heart disease (CHD) and advanced heart failure (HF).

Background: Ambulatory pulmonary artery (PA) pressure monitoring with implantable hemodynamic monitors (IHMs) has been shown to reduce HF-related hospital admissions in non-CHD populations. HF is a common late cardiovascular complication in adult CHD necessitating better understanding of IHM application in this population.
