Achieving health equity in populations with congenital heart disease (CHD) requires recognizing existing disparities throughout the lifespan that negatively and disproportionately impact specific groups of individuals. These disparities occur at individual, institutional, or system levels and often result in increased morbidity and mortality for marginalized or racially minoritized populations (population subgroups (e.g., ethnic, racial, social, religious) with differential power compared to those deemed to hold the majority power in the population). Creating actionable strategies and solutions to address these health disparities in patients with CHD requires critically examining multilevel factors and health policies that continue to drive health inequities, including varying social determinants of health (SDOH), systemic inequities, and structural racism. In this comprehensive review article, we focus on health equity solutions and health policy considerations for minoritized and marginalized populations with CHD throughout their lifespan in the United States. We review unique challenges that these populations may face and strategies for mitigating disparities in lifelong CHD care. We assess ways to deliver culturally competent CHD care and to help lower-health-literacy populations navigate CHD care. Finally, we review system-level health policies that impact reimbursement and research funding, as well as institutional policies that impact leadership diversity and representation in the workforce.

Introduction: Fontan pathway obstruction is a serious complication characterized by an anatomical or functional narrowing anywhere in the cavo-pulmonary pathways. Here we report the first case where an innovative Fontan conduit rehabilitation procedure with intravascular lithotripsy was used achieving a significant increase in the pathway size. Case: A 28-year-old male with tricuspid atresia status-post Fontan palliation (age 23 months) with bare metal stent implant to treat obstruction at age 15, presented with syncope, ascites and varicose veins. Imaging studies revealed a cirrhotic liver morphology and Fontan pathway obstruction with minimal diameter of 12 mm. Cardiac catheterization confirmed severe Fontan conduit obstruction in addition to LPA stenosis. Serial covered Cheatham-Platinum stents were implanted for conduit coverage followed by Palmaz stents. Non-compliant Atlas balloon dilation to 20 atm was performed without expansion of the Fontan pathway beyond 12 mm due to severe calcification. A 7.0 x 60 mm shock-wave lithotripsy balloon was added alongside the Atlas balloon to modulate the heavily calcified wall with subsequent expansion of the conduit to 21 mm after inflating the Atlas balloon to 14 atm. Discussion: Several studies demonstrated that transcatheter stenting of stenotic Fontan conduits can be safely performed. Intravascular lithotripsy has emerged as a novel therapy for the treatment of coronary vascular calcification. We report the first case of an innovative percutaneous Fontan conduit rehabilitation procedure using a lithotripsy shock wave balloon in an adult with severely calcified Fontan pathway obstruction and prior stents, achieving a 75% increase in the pathway size without significant complications. Further studies are needed to evaluate the long-term safety and efficacy of this novel approach, but this case presents an exciting option for future directions in the percutaneous treatment of Fontan pathway obstruction.

Abstract Background Malignancy is known to be a major cause of death in adult congenital heart disease (ACHD). However, data regarding cardiovascular and cancer-related outcomes in ACHD are lacking. Methods We conducted a retrospective single-center cohort study comprising patients with ACHD and malignancy. The primary outcome was all-cause mortality. Key Secondary outcomes included major adverse cardiovascular and cerebrovascular events (MACCE), cardiotoxicity events and consequent cancer therapy modifications. Results Sixty-eight patients with ACHD and a history of cancer were included in the study. 82% of patients had moderate or great ACHD anatomic complexity. Over a median follow-up of 5 years after cancer diagnosis, 16 (24%) patients died, with 69% of deaths being due to cancer. Univariate predictors of mortality were baseline arrhythmia (OR 3.82, 95% CI 1.15-12.67, p = 0.028), baseline diuretic therapy (OR 3.54, 95% CI 1.04-12.04, p = 0.044) and advanced cancer stage at diagnosis (OR 2.37, 95% CI 1.32-4.25, p = 0.004). MACCE occurred in 40 (59%) patients and was independently predicted by baseline diuretic requirement (OR 9.91, 95% CI 1.12 - 87.85, p = 0.039). A14% incidence of cardiotoxicity was seen; 3 patients needed modification and 1 patient needed temporary interruption of cancer therapy for 2 weeks. Conclusions Considerable mortality occurred in this cohort of patients with ACHD and cancer; most deaths were cancer-related. A high rate of MACCE was observed, yet rates of obligatory modification of cancer therapy due to cardiotoxicity were low.
