Cardiovascular disease remains a leading cause of morbidity and mortality in adults despite recent scientific advancements. Although people are living longer lives, there may be an adverse impact on quality of life, necessitating a greater need for palliative care services and support. Palliative care for adults with advanced cardiovascular disease has the potential to significantly improve quality of life for individuals living with cardiovascular disease and their informal care partners. Effective communication, shared decision-making, age-friendly care principles, and advance care planning are vital components of palliative care and support comprehensive and holistic care throughout the advanced cardiovascular disease trajectory and across care settings. Current evidence highlights the benefits of palliative care in managing symptoms, reducing psychological distress, and supporting both people with cardiovascular disease and their care partners. However, significant gaps exist in palliative care research related to non-heart failure populations, care partner outcomes, and palliative care implementation in diverse populations. This scientific statement (1) discusses the application of effective communication, shared decision-making, age-friendly care, and advance care planning in advanced cardiovascular disease palliative care; (2) provides a summary of recent evidence related to palliative care and symptom management, quality of life, spiritual and psychological support, and bereavement support in individuals with advanced cardiovascular disease and their care partners; (3) discusses issues involving diversity, equity, and inclusion in cardiovascular disease palliative care; (4) highlights the ethical and legal concerns surrounding palliative care and implanted cardiac devices; and (5) provides strategies for palliative care engagement in adults with advanced cardiovascular disease for the care team.

Single ventricle congenital heart disease like hypoplastic left heart syndrome with a Fontan circulation constitutes, the largest group of children hospitalized with circulation failure, experiencing an in-hospital mortality rate of 20% to 50%. We investigated the mechanisms leading to Fontan failure to identify novel therapeutic targets.

The growing morbidity, mortality, and health care costs related to heart failure (HF) underscore the urgent need to prioritize its primary prevention. Whereas a risk-based approach for HF prevention remains in its infancy, several key opportunities exist to actualize this paradigm in clinical practice. First, the 2022 American Heart Association/American College of Cardiology/Heart Failure Society of America HF guidelines provided recommendations, for the first time, on the clinical utility of multivariable risk equations to estimate risk of incident HF. Second, the American Heart Association recently developed the PREVENT (Predicting Risk of Cardiovascular Disease Events) equations, which not only enable prediction of incident HF separately, but also include HF in the prediction of total cardiovascular disease. Third, the predominant phenotype of HF risk has emerged as the cardiovascular-kidney-metabolic syndrome. Fourth, the emergence of novel therapies that prevent incident HF (eg, sodium-glucose cotransporter-2 inhibitors) and target multiple cardiovascular-kidney-metabolic axes demonstrate growing potential for risk-based interventions. Whereas the concept of risk-based prevention has been established for decades, it has only been operationalized for atherosclerotic cardiovascular disease prevention to date. Translating these opportunities into a conceptual framework of risk-based primary prevention of HF requires implementation of PREVENT-HF (Predicting Risk of Cardiovascular Disease Events-Heart Failure) equations, targeted use of cardiac biomarkers (eg, natriuretic peptides) and echocardiography for risk reclassification and earlier detection of pre-HF, and definition of therapy-specific risk thresholds that incorporate net benefit and cost-effectiveness. This scientific statement reviews the current evidence for accurate risk prediction, defines strategies for equitable prevention, and proposes potential strategies for the successful implementation of risk-based primary prevention of HF.

Previous studies have shown weak agreement between coronary physiology indices derived from continuous and bolus thermodilution, and suggested greater variability with bolus thermodilution measurements. This study aimed to evaluate the repeatability and correlation of continuous and bolus thermodilution-derived physiology indices in cardiac transplant recipients.

Few middle-aged and older adults engage in regular leisure-time exercise. Incidental physical activity (IPA) encompasses activities of daily living outside the leisure-time domain. No dose-response study is available to guide IPA-focused interventions and guidelines. We examined the associations of device-assessed IPA intensities (vigorous [VIPA], moderate [MIPA], light [LIPA]) with major adverse cardiovascular events (MACE) and mortality, and we estimated the "health equivalence" of LIPA and MIPA against 1 minute of VIPA.

Heart failure is a growing health-care concern affecting tens of millions of individuals globally. Although traditional therapeutic strategies have focused on reducing the risk for hospitalization and mortality, the importance of patient-reported outcomes (PROs) in patients with heart failure is increasingly being recognized. Regulatory agencies consider PROs part of their evaluation of drugs and devices, and professional society guidelines may recommend interventions that improve PROs. However, for several reasons, the effect of interventions on PROs reported in heart failure trials currently is difficult to interpret. There is no consensus on the timing and frequency of PRO assessments. Moreover, it has been difficult to establish a minimal clinically important difference, that is, the minimal change in a PRO score that is meaningful to a patient. In addition, traditional methods of analyzing and reporting PROs such as comparison of mean differences across groups or responder analysis are prone to statistical artifacts and misinterpretation. This article presents an in-depth discussion of these issues, with the Kansas City Cardiomyopathy Questionnaire used as an example, to facilitate the use of PROs in heart failure research, regulatory, and clinical settings.

Paravalvular leaks (PVLs) after transcatheter aortic valve replacement have a significant prognostic impact, and valve oversizing, particularly with self-expanding valves, may prevent postprocedural PVL occurrence. Recent iterations of the Evolut valve system are intended to reduce PVL, but the effects of oversizing with such valves on PVL are largely unknown. We aimed to assess, in a real-world contemporary setting, the impact of Evolut valve oversizing on PVL after transcatheter aortic valve replacement.

Acute right ventricular failure (ARVF) is commonly seen in the intensive care unit and constitutes a significant clinical challenge, with associated high in-hospital mortality. Recently, the treatment of ARVF has significantly changed, with the progressive implementation of mechanical circulatory support devices that now represent important tools for clinicians in treating this condition. However, despite recent advancements, the optimal approach for ARVF remains elusive, and precise treatment algorithms and comprehensive management protocols are still lacking. In the present review, we explore the pathophysiology of ARVF, highlighting the different mechanisms that may lead to this clinical entity and emphasizing the left and right heart's complex interplay. We analyze the different therapeutic options that are now available for short- and long-term management of ARVF, with a particular focus on the advantages and disadvantages of the mechanical circulatory support devices actually used. Furthermore, we propose future directions in the field and a possible flowchart for the treatment of this condition.

Hemodynamically guided management of patients with chronic heart failure (HF), using a remote, ambulatory pulmonary artery (PA) pressure monitor, has been shown to reduce mortality and morbidity. These improved outcomes were associated with a reduction in PA pressure. However, several pivotal questions remain unanswered: do systolic, diastolic, or mean PA pressures each predict all-cause mortality? Do PA pressures predict mortality across the ejection fraction (EF) spectrum? Do increases or decreases in PA pressure over time predict increases or decreases in mortality?

Chronic total occlusion percutaneous coronary intervention has evolved into a subspecialty of interventional cardiology. Using a variety of antegrade and retrograde techniques, experienced operators currently achieve success rates of 85% to 90%, with an incidence of major periprocedural complications of ≈2% to 3%. Several developments in equipment (new microcatheters and guidewires, novel reentry devices), imaging (computed tomography angiography guidance, intravascular imaging for reentry), techniques (intraocclusion contrast injection, advanced subintimal tracking and reentry), and artificial intelligence (automated computed tomography image analysis and prediction of the likelihood of crossing success with various techniques) could further improve outcomes. Global collaboration and rapid dissemination of new developments accelerate the pace of progress. While innovation is exciting and necessary, adhering to the basic principles of chronic total occlusion percutaneous coronary intervention (such as continual assessment of risks and benefits, meticulous angiographic review, and use of dual injection) remains critical for achieving optimal patient outcomes.

Poor sleep health is associated with cardiometabolic disease and related risk factors, including heart disease, stroke, elevated blood pressure and lipid levels, inflammation, glucose intolerance, obesity, physical inactivity, poor diet, unhealthy substance use, poor mental health, and increased all-cause and cardiovascular mortality, and is associated with social determinants of cardiovascular health and health disparities. Therefore, sleep duration has been recognized by the American Heart Association as one of Life's Essential 8. Although chronic sleep duration is the sole metric used in Life's Essential 8, sleep health represents a multidimensional construct. This scientific statement outlines the concept of multidimensional sleep health (sleep duration, continuity, timing, regularity, sleep-related daytime functioning, architecture, and absence of sleep disorders) as it applies to cardiometabolic health. Considerations of how these dimensions are related to cardiometabolic health and patterned by sociodemographic status are explained, and knowledge gaps are highlighted. Additional data are needed to understand better how these various dimensions of sleep should be assessed and how interventions targeting sleep health in clinical and community settings can be leveraged to improve health.

The anatomic and physiological changes associated with severe aortic stenosis may influence the functional evaluation of coronary stenoses. In this study, we aimed to assess changes in functional resting and hyperemic indices before and immediately after transcatheter aortic valve implantation (TAVI) and their relationship with microvascular resistance.
