COVID-19 impact on adults with congenital heart disease self-perceived vulnerability and coping.

The COVID-19 pandemic poses risk for worsened quality of life in patients with adult congenital heart disease. In a qualitative thematic analysis of semi-structured interviews conducted July 2020 to August 2021, we examined the pandemic's impact on participants' (N = 25) experiences with self-perception and coping. All had moderate or complex disease; median age 32 years. The pandemic altered some participants' self-perception, including increased vulnerability beyond heart-attributed risk. Restrictions frequently prevented participants from using their usual coping strategies, forcing use of alternative methods. For an already at-risk population, these findings suggest the need for increased mental health awareness, assessment, and support.

AHA/ACC vs ESC Guidelines for Management of Adults With Congenital Heart Disease: JACC Guideline Comparison.

The American Heart Association and American College of Cardiology published practice guidelines for the management of adult congenital heart disease in 2018 and the European Society of Cardiology published analogous guidelines in 2020. Although there are broad areas of consensus between the 2 documents, there are important differences that impact patient management. This review discusses key areas of agreement and disagreement between the 2 guidelines, with discussion of possible reasons for disagreement and potential implications.

ACC/AHA/ASE/HRS/ISACHD/SCAI/SCCT/SCMR/SOPE 2020 Appropriate Use Criteria for Multimodality Imaging During the Follow-Up Care of Patients With Congenital Heart Disease: A Report of the American College of Cardiology Solution Set Oversight Committee and Appropriate Use Criteria Task Force, American Heart Association, American Society of Echocardiography, Heart Rhythm Society, International Society for Adult Congenital Heart Disease, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and Society of Pediatric Echocardiography.

The American College of Cardiology (ACC) collaborated with the American Heart Association, American Society of Echocardiography, Heart Rhythm Society, International Society for Adult Congenital Heart Disease, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and the Society of Pediatric Echocardiography to develop Appropriate Use Criteria (AUC) for multimodality imaging during the follow-up care of patients with congenital heart disease (CHD). This is the first AUC to address cardiac imaging in adult and pediatric patients with established CHD. A number of common patient scenarios (also termed "indications") and associated assumptions and definitions were developed using guidelines, clinical trial data, and expert opinion in the field of CHD.1 The indications relate primarily to evaluation before and after cardiac surgery or catheter-based intervention, and they address routine surveillance as well as evaluation of new-onset signs or symptoms. The writing group developed 324 clinical indications, which they separated into 19 tables according to the type of cardiac lesion. Noninvasive cardiac imaging modalities that could potentially be used for these indications were incorporated into the tables, resulting in a total of 1,035 unique scenarios. These scenarios were presented to a separate, independent panel for rating, with each being scored on a scale of 1 to 9, with 1 to 3 categorized as "Rarely Appropriate," 4 to 6 as "May Be Appropriate," and 7 to 9 as "Appropriate." Forty-four percent of the scenarios were rated as Appropriate, 39% as May Be Appropriate, and 17% as Rarely Appropriate. This AUC document will provide guidance to clinicians in the care of patients with established CHD by identifying the reasonable imaging modality options available for evaluation and surveillance of such patients. It will also serve as an educational and quality improvement tool to identify patterns of care and reduce the number of Rarely Appropriate tests in clinical practice.

Barriers and Facilitators of Palliative Care and Advance Care Planning in Adults With Congenital Heart Disease.

Palliative care has potential to improve quality of life and goal-concordant care for patients with adult congenital heart disease (ACHD). However, it is rarely employed prior to critical illness because the best methods for implementation are not well-defined. We qualitatively evaluated ACHD patients' understanding of and opinions regarding palliative care and advance care planning (ACP) to better define the needs of this population. We conducted a thematic analysis of 25 semistructured interviews with patients with ACHD in which we assessed participants' perspectives on the need for, and barriers and facilitators to, the use of palliative care and ACP. In a group of participants with ACHD (mean age 38, 48% male) classified as simple (24%), moderate (32%), or complex (44%), we identified 4 major themes: (1) using knowledge to combat future uncertainties; (2) unfamiliarity with and limited exposure to palliative care and ACP; (3) facilitators and barriers to engaging in palliative care and ACP; and (4) importance of timing and presentation of ACP discussions. In conclusion, participants expressed a desire for knowledge about ACHD progression and treatment. They supported routine incorporation of palliative care and ACP and identified related facilitators and barriers to doing so. Importantly, timing and format of these discussions must be individualized using shared decision-making between clinicians, patients, and their families.

Acute Increase in Deaths Among Patients With Adult Congenital Heart Disease During COVID-19: Single-Center Experience.

Fear of acquiring severe acute respiratory syndrome coronavirus-2 infection is a major contributor to underutilization of the health care system during the current pandemic. In this report, we describe 4 cases of unexpected deaths that occurred within a short time period in patients with adult congenital heart disease without warning symptoms. (Level of Difficulty: Intermediate.).

Heart Failure in Adult Congenital Heart Disease.

As the population of adult congenital heart disease patients ages and grows, so too does the burden of heart failure in this population. Despite the advances in medical and surgical therapies over the last decades, heart failure in adult congenital heart disease remains a formidable complication with high morbidity and mortality. This review focuses on the challenges in determining the true burden and management of heart failure in adult congenital heart disease. There is a particular focus on the need for developing a common language for classifying and reporting heart failure in adult congenital heart disease, the clinical presentation and prognostication of heart failure in adult congenital heart disease, the application of hemodynamic evaluation, and advanced heart failure treatment. A common case study of heart failure in adult congenital heart disease is utilized to illustrate these key concepts.

What Every Cardiologist Should Know About the 2018 Updated Adult Congenital Cardiology Guidelines.

PURPOSE OF REVIEW: Review the recently updated guidelines for the management of patients with adult congenital heart disease (ACHD) with a focus on the changes between these guidelines and the prior guidelines. RECENT FINDINGS: The 2018 guidelines for the management of patients with ACHD focused on utilizing the available data and limiting the number recommendations based only on expert opinion. These guidelines implement a new anatomic and physiological classification scheme to guide management of patients, which takes into account both the underlying anatomy as well as residual cardiac disease and symptoms. Given a lack of robust outcomes data for many types of CHD, the new guidelines provide fewer total recommendations than the prior version, emphasizing the data that is available and drawing attention to the need for additional data. The 2018 guidelines provide the field with a comprehensive update in the management of ACHD patients with an emphasis on the available data.

Long-Term Right Ventricular Assist Device Therapy in an Adult with Pulmonary Atresia/Intact Ventricular Septum.

Durable ventricular assist device (VAD) support is uncommonly employed in adult congenital heart disease and often involves supporting a systemic right ventricle (RV). Ventricular assist device support of a subpulmonic RV is even more unusual.

Durable mechanical circulatory support in teenagers and adults with congenital heart disease: A systematic review.

BACKGROUND: Heart failure is the leading cause of morbidity and mortality for adults with congenital heart disease (ACHD). Many patients are ineligible for transplantation, and those who are eligible often face long wait times with high wait-list morbidity. Durable mechanical circulatory support (MCS) may be an option for many patients. This systematic review evaluates the published literature on the use of durable MCS in teenagers and adults with congenital heart disease. METHODS: A comprehensive search of MEDLINE (PubMed), EMBASE, and the Cochrane Library was performed electronically in July 2015 and updated in March 2016, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. RESULTS: Individual case reports and several case series identified 66 patients with ACHD treated with durable MCS. More than half were INTERMACS 1 or 2 at the time of implantation. Patients with Fontan repairs were more frequently classified as INTERMACS 1 or 2 (89% compared to 59% or less among other groups). Cases published after 2010 showed a trend toward less severe INTERMACS status, and patients were less likely to have received transplants by the time of reporting (31% compared to 61% prior). Durable MCS was implanted as bridge-to-transplant in 77%. Patients with Fontan repair accounted for 14% of cases. CONCLUSION: Reports of durable MCS utilization in patients with ACHD are becoming more frequent and devices are being implanted in more stable patients. Reports are mostly case reports or small case series so reporting bias is likely and prospective protocoled reporting is needed.

Maternal and Fetal Outcomes of Anticoagulation in Pregnant Women With Mechanical Heart Valves.

BACKGROUND: Anticoagulation for mechanical heart valves during pregnancy is essential to prevent thromboembolic events. Each regimen has drawbacks with regard to maternal or fetal risk. OBJECTIVES: This meta-analysis sought to estimate and compare the risk of adverse maternal and fetal outcomes in pregnant women with mechanical heart valves who received different methods of anticoagulation. METHODS: Studies were identified using a Medline search including all publications up to June 5, 2016. Study inclusion required reporting of maternal death, thromboembolism, and valve failure, and/or fetal spontaneous abortion, death, and congenital defects in pregnant women treated with any of the following: 1) a vitamin K antagonist (VKA) throughout pregnancy; 2) low-molecular-weight heparin (LMWH) throughout pregnancy; 3) LMWH for the first trimester, followed by a VKA (LMWH and VKA); or 4) unfractionated heparin for the first trimester, followed by a VKA (UFH and VKA). RESULTS: A total of 800 pregnancies from 18 publications were included. Composite maternal risk was lowest with VKA (5%), compared with LMWH (16%; ratio of averaged risk [RAR]: 3.2; 95% confidence interval [CI]: 1.5 to 7.5), LMWH and VKA (16%; RAR: 3.1; 95% CI: 1.2 to 7.5), or UFH and VKA (16%; RAR: 3.1; 95% CI: 1.5 to 7.1). Composite fetal risk was lowest with LMWH (13%; RAR: 0.3; 95% CI: 0.1 to 0.8), compared with VKA (39%), LMWH and VKA (23%), or UFH and VKA (34%). No significant difference in fetal risk was observed between women taking ≤5 mg daily warfarin and those with an LMWH regimen (RAR: 0.9; 95% CI: 0.3 to 2.4). CONCLUSIONS: VKA treatment was associated with the lowest risk of adverse maternal outcomes, whereas the use of LMWH throughout pregnancy was associated with the lowest risk of adverse fetal outcomes. Fetal risk was similar between women taking ≤5 mg warfarin daily and women treated with LMWH.

Early outcomes in patients undergoing transcatheter versus surgical pulmonary valve replacement.

OBJECTIVES: To identify predictors of morbidity and mortality in patients undergoing either transcatheter pulmonary valve replacement (TPVR) or surgical pulmonary valve replacement (SPVR) in an effort to quantify any early benefit of TPVR over SPVR. METHODS: Using a risk-adjusted propensity score model, we compare early major morbidity and mortality between patients undergoing SPVR and TPVR at our institution between January 2006 and January 2014. RESULTS: 145 patients in the SPVR cohort and 78 patients in the TPVR cohort were included. Primary pulmonary regurgitation was more common in the SPVR group (76.6% vs 23.1%, p<0.001) and primary pulmonary stenosis was more common in the TPVR group (9.7% vs 44.9%, p< 0.001). In unadjusted analysis, major morbidity and mortality occurred in 11.7% of SPVR patients versus 3.8% of TPVR patients (p=0.04). However, following risk adjustment and inclusion of a propensity score, no significant difference was seen between the two modalities. A larger right ventricular end-diastolic dimension (RVEDVI) was the only preoperative variable associated with the primary end point (OR 1.013/10 mL/m2 increase, p=0.03). Hospital length of stay was significantly longer in patients undergoing SPVR (6.9±1.0 days SPVR vs 1.2±0.3 days TPVR, p<0.0001), with similar hospital costs between groups (mean: US$44 660±5071 SPVR vs US$48 355±1000 TPVR, p=0.7). CONCLUSIONS: Following risk adjustment, no significant differences were observed between SPVR and TPVR strategies. TPVR was associated with a shorter hospitalisation; however, total hospitalisation costs were similar between groups.

Metabolic Syndrome in Adults With Congenital Heart Disease.

BACKGROUND: Metabolic syndrome increases risk for atherosclerotic coronary artery disease, and its prevalence increases with increasing age and body mass index. Adults with congenital heart disease (ACHD) are now living longer and accruing coronary artery disease risk factors. However, the prevalence of metabolic syndrome in ACHD patients is unknown. METHODS AND RESULTS: We conducted a retrospective cohort study of ACHD patients at our center to quantify the prevalence of metabolic syndrome in an ACHD population. Using case-control matching, we constructed a comparable control group from a population-based sample of 150 104 adults. International Diabetes Federation criteria were used to define metabolic syndrome. We used logistic regression to compare the risk of metabolic syndrome across the resulting cohorts, which were composed of 448 ACHD patients and 448 controls matched by age and sex. Mean age of both groups was 32.4±11.3 years, and 51.3% were female. Obesity was present in 16.1% of the ACHD patients and 16.7% of the controls. Metabolic syndrome was more common in ACHD patients than in controls (15.0% versus 7.4%; odds ratio 1.82, 95% CI 1.25-2.65). CONCLUSIONS: Our data suggest that metabolic syndrome is more common among adults with congenital heart disease than in the general population. Thus, patients with congenital heart disease should be screened for metabolic syndrome and risk factors mitigated where possible to prevent atherosclerotic coronary artery disease. Preventive cardiology should be included during routine ACHD care.
