Pulmonary vasodilators have the potential to improve such haemodynamics. The aim of this study was to assess the acute effects of exercise on liver stiffness and venous pressures and to assess the impact of inhaled Treprostinil on this response.

Ebstein's Anomaly of the Tricuspid Valve: an Overview of Pathology and Management.

Purpose Of Review: Ebstein's anomaly (EA) is a rare, but complex form of congenital heart disease consisting of a right ventricular myopathy and morphologic tricuspid valve disease leading to a high incidence of right ventricular dysfunction and arrhythmias. This review offers an updated overview of the current understanding and management of patients with EA with a focus on the adult population.

Recent Findings: Increased understanding of anatomic accessory atrioventricular pathways in EA has resulted in an improvement in ablation techniques and long-term freedom of atrial arrhythmia recurrence.

Hepatocellular carcinoma and the Fontan circulation: Clinical presentation and outcomes.

Background: Fontan-associated liver disease (FALD) is universal in patients with a Fontan circulation. Hepatocellular carcinoma (HCC) is one of its severe expressions, and, though rare, frequently fatal. The purpose of this study was to describe the clinical presentation, risk factors, and outcomes of HCC in patients with a Fontan circulation.

Factors affecting early-life intestinal microbiota development.

This paper reviews the published evidence on early-life intestinal microbiota development, as well as the different factors influencing its development before, at, and after birth. A literature search was done using PubMed, Cochrane and EMBASE databases. A growing body of evidence indicates that the intrauterine environment is not sterile as once presumed, but that maternal-fetal transmission of microbiota occurs during pregnancy.

Atrioventricular Valve Regurgitation in Single Ventricle Heart Disease: A Common Problem Associated With Progressive Deterioration and Mortality.

The Fontan procedure has provided patients with single ventricle physiology extended survival into adulthood and in many cases has improved their quality of life. Atrioventricular valve regurgitation (AVVR) is common in single ventricle patients and is associated with increased risk of mortality. AVVR is more common in patients with a systemic tricuspid or common atrioventricular valve but is generally progressive irrespective of underlying valve morphology.

Risk Factors for Mortality and Ventricular Tachycardia in Patients With Repaired Tetralogy of Fallot: A Systematic Review and Meta-analysis.

Background: Patients with repaired tetralogy of Fallot (rTOF) have increased risk for mortality, sudden cardiac death, and ventricular tachycardia (VT). The aim of this systematic review and meta-analysis is to offer an updated analysis of risk factors following significant changes in surgical and perioperative management.

Methods: A meta-analysis based on the published literature between 2008 and 2018 was conducted.

Lymphopenia in adults after the Fontan operation: prevalence and associations.

Lymphopenia is common in adults who have had a Fontan operation although its aetiology and clinical implications remain unknown. Previous work suggests an association between lymphopenia and both liver disease and splenomegaly. The objective of this study was to assess the prevalence of lymphopenia in adults with a Fontan circulation and evaluate its associations with risk factors and clinical outcomes.

Abdominal Skeletal Muscle Index as a Potential Novel Biomarker in Adult Fontan Patients.

Background: Fontan palliation results in a chronic multisystem disorder with diminished exercise capacity and increased risk of muscle wasting. The aims of this study were to assess the feasibility of skeletal muscle mass measurements in Fontan patients undergoing magnetic resonance imaging liver surveillance to compare muscle mass with a historic control and to assess its correlation with cardiorespiratory fitness.

Methods: Skeletal muscle area (SMA) and skeletal muscle index (SMI) were measured at T12 and L3.

Thromboembolic Events Are Independently Associated with Liver Stiffness in Patients with Fontan Circulation.

Thromboembolism (TE) and Fontan-associated liver disease (FALD) are common and lead to significant morbidity in Fontan circulations. Risk factors for TE and the potential link between TE and FALD are not well understood. The objective of this study was to evaluate the association between TE and the severity of FALD based on radiologic liver stiffness.

Timing of Repair in Tetralogy of Fallot: Effects on Outcomes and Myocardial Health.

Early complete repair of tetralogy of Fallot (ToF) prior to 1 year of age has been demonstrated to be safe and has survival benefits over late repair. The age at repair of ToF affects long-term outcomes. This may largely be related to preserved, or comparatively better, myocardial health.

Relation of Magnetic Resonance Elastography to Fontan Failure and Portal Hypertension.

Fontan associated liver disease is associated with morbidity and mortality in palliated single-ventricle congenital heart disease patients. Magnetic resonance elastography (MRE) provides a quantitative assessment of liver stiffness in Fontan patients. We hypothesized that MRE liver stiffness correlates with liver enzymes, hemodynamics, portal hypertension, and Fontan failure (FF).

Myocardial blood flow and cardiac sympathetic innervation in young adults late after arterial switch operation for transposition of the great arteries.

Background: The arterial switch operation (ASO) for repair of transposition of the great arteries (TGA) requires transection of the great arterial trunks and re-implantation of the coronary arteries into the neoaortic root resulting in cardiac sympathetic denervation which may affect myocardial blood flow (MBF) regulation. The aims of the present study were to evaluate sympathetic (re-)innervation in young adults after ASO and its impact on MBF.

Methods: Twelve patients (age 22.

Quantification of intrathoracic fat adds prognostic value in women undergoing myocardial perfusion imaging.

Aim: Amongst patients with coronary artery disease (CAD), women experience relatively worse outcomes as compared to men. Evidence to date has failed to explore unique female imaging targets as major determinants of cardiovascular risk. We sought to assess the prognostic value of epicardial (EFV) and intrathoracic fat volume (IFV) quantification in women and men with suspected and known CAD.
