Background: Hypertension significantly contributes to global morbidity and mortality rates. Refugees are often exposed to significant risk factors that increase their chances of developing hypertension; however, the prevalence of hypertension among resettled refugees remains understudied. This study estimates and compares the prevalence of hypertension, levels of awareness, and access to care between two groups of Syrian refugees residing in humanitarian settings in Lebanon and Denmark.

Patent ductus arteriosus (PDA) stenting is an established alternative to systemic-to-pulmonary artery shunts for neonates with ductal-dependent pulmonary blood flow, offering a less invasive approach. However, the procedure remains technically challenging and prone to complications. We evaluated the wire twisting/locking technique to improve precision and safety during PDA stenting.

Background: Patients with repaired tetralogy of Fallot (rTOF) are commonly followed with cardiovascular magnetic resonance (CMR) imaging and frequently develop right ventricular (RV) dysfunction, which can be severe enough to impact left ventricular (LV) function in some patients. In this study, we sought to characterize patterns of LV dysfunction in this patient population using deep learning synthetic strain (DLSS), a fully automated deep learning algorithm capable of measuring regional LV strain and dyssynchrony.

Methods: We retrospectively collected cine steady-state free precession (SSFP) MRI images from a multi-institutional cohort of 198 patients with rTOF and 21 healthy controls.

Background: Evaluating regional variations in right ventricular (RV) performance can be challenging, particularly in patients with significant impairments due to the need for 3D spatial coverage with high spatial resolution. ECG-gated cineCT can fully visualize the RV and be used to quantify regional strain with high spatial resolution. However, strain is influenced by loading conditions.

Background: Regional myocardial work (MW) is not measured in the right ventricle (RV) due to a lack of high spatial resolution regional strain (RS) estimates throughout the ventricle. We present a cineCT-based approach to evaluate regional RV performance and demonstrate its ability to phenotype three complex populations: end-stage LV failure (HF), chronic thromboembolic pulmonary hypertension (CTEPH), and repaired tetralogy of Fallot (rTOF).

Methods: 49 patients (19 HF, 11 CTEPH, 19 rTOF) underwent cineCT and right heart catheterization (RHC).

Article Synopsis
  • COVID-19 significantly affects coagulation in adult patients with congenital heart disease (ACHD), making them more susceptible to thromboembolic (TE) and bleeding complications.
  • In a study from May 2020 to November 2021 involving nearly 2,000 ACHD patients, 1.5% experienced severe TE or bleeding events, which were linked to higher mortality rates and more advanced health conditions.
  • Key risk factors for these complications included prior anticoagulation treatment, incidents of cardiac injury, and severity of the COVID-19 infection, with logistic regression confirming their independent associations with TE and bleeding risks.

The rate of heart transplantation in adults with congenital heart disease (ACHD) is rising, but the 1-year mortality posttransplantation remains higher than non-ACHD patients. A robust pretransplant assessment and operative and postoperative planning can mitigate much of the perioperative risk. Importantly, ACHD patients who survive the first year have significantly better 10-year survival compared with non-ACHD patients.

Article Synopsis
  • An increasing number of adult Fontan patients are needing heart or combined heart-liver transplants, but there is limited data on their outcomes and ideal referral timing.
  • This study analyzed 131 adult Fontan patients who underwent transplantation between 1995 and 2021, finding a 79% survival rate at one year and 66% at five years post-transplant, with improved outcomes noted in patients transplanted after 2010.
  • Late referrals and certain health indicators like poor functional status and specific vascular issues were linked to lower survival rates, highlighting the importance of timely evaluations.

Article Synopsis
  • - The study investigates the effects of Fontan-associated liver disease (FALD) on post-transplant outcomes, specifically looking at heart transplant (HT) versus combined heart-liver transplant (CHLT) in adult Fontan patients.
  • - Results showed that CHLT patients were generally older and had higher FALD scores, but they exhibited better survival rates compared to HT, particularly in those with higher FALD scores.
  • - The research indicates a correlation between higher FALD scores and increased mortality post-transplant, suggesting that CHLT may offer improved survival outcomes for patients with significant liver disease.

Background: Prestenting of the landing zone for transcatheter pulmonary valve replacement (TPVR) with a balloon-expandable valve can dilate a stenotic right ventricular outflow tract (RVOT), prevent paravalvar leak (PVL), and protect against conduit tear. Simultaneous stenting (SS) with the Melody valve has been described, but to our knowledge, SS with a SAPIEN valve has not been reported. We report our experience with this novel technique.

Background: The prognosis and therapeutic responses are worse for pulmonary arterial hypertension associated with systemic sclerosis (SSc-PAH) compared with idiopathic pulmonary arterial hypertension (IPAH). This discrepancy could be driven by divergence in underlying metabolic determinants of disease.

Research Question: Are circulating bioactive metabolites differentially altered in SSc-PAH vs IPAH, and can this alteration explain clinical disparity between these PAH subgroups?

Study Design And Methods: Plasma biosamples from 400 patients with SSc-PAH and 1,082 patients with IPAH were included in the study.

Introduction: The number of heart transplants in adults with congenital heart disease (CHD) is increasing, though outcomes remain unfavorable compared to those without CHD. The etiology of this mortality difference remains uncertain. Panel reactive antibody (PRA) is a predictor of survival post-transplantation, and adult CHD patients have been observed to have higher PRA levels.
