Exercise adult congenital heart disease

BACKGROUND: Existing models for prediction of major adverse cardiovascular events (MACE) after repair of tetralogy of Fallot have been limited by modest predictive capacity and limited applicability to routine clinical practice. We hypothesized that an artificial intelligence model using an array of parameters would enhance 5-year MACE prediction in adults with repaired tetralogy of Fallot. METHODS: A machine learning algorithm was applied to 2 nonoverlapping, institutional databases of adults with repaired tetralogy of Fallot: (1) for model development, a prospectively constructed clinical and cardiovascular magnetic resonance registry; (2) for model validation, a retrospective database comprised of variables extracted from the electronic health record...

There is increasing effort in both the inpatient and outpatient setting to improve care, function, and quality of life for children with congenital heart disease, and to decrease complications. As the mortality rates of surgical procedures for congenital heart disease decrease, improvement in perioperative morbidity and quality of life have become key metrics of quality of care. Quality of life and function in patients with congenital heart disease can be affected by multiple factors: the underlying heart condition, cardiac surgery, complications, and medical treatment...

BACKGROUND AND AIMS: In adults with congenital heart disease and systemic right ventricles, progressive right ventricular systolic dysfunction is common and is associated with adverse outcomes. Our aim was to assess the impact of the phosphodiesterase-5-inhibitor tadalafil on right ventricular systolic function. METHODS AND RESULTS: This was a double-blind, randomized, placebo-controlled, multi-center superiority trial (NCT03049540) involving 100 adults with systemic right ventricles (33 women, mean age: 40...

BACKGROUND: A progressively increasing prevalence of congenital heart disease (CHD) in adulthood has been noticed in recent decades; CHD cases with a systemic right ventricle have a poorer outcome. METHODS: Seventy-three patients with SRV evaluated in an outpatient clinic between 2014 and 2020 were enrolled in this study. Thirty-four patients had a transposition of the great arteries treated with an atrial switch operation; 39 patients had a congenitally corrected transposition of the great arteries (ccTGA)...

BACKGROUND: Peak oxygen consumption (VO<inf>2peak</inf>), which depends on maximal exertion and is reduced in adults with congenital heart disease (ACHD), is associated with lesion severity. The lowest ventilatory equivalent for oxygen (the minimum value of VE/VO<inf>2</inf>) reflects the cardiorespiratory optimal point (COP) as best possible respiration-circulatory interaction and may discriminate between lesion types without the need for maximal exertion. However, data on COP in ACHD is scarce...

BACKGROUND: Coronary artery anomalies are characterized by an abnormality in the course or origin of three main coronary arteries. There needs to be more scientific evidence to promptly treat coronary artery anomalies with poorly understood prognostic implications, especially anomalous aortic origin of the right coronary artery from the left coronary cusp. CASE PRESENTATION: A 58-year-old Caucasian female presented multiple times over 6 months with atypical chest discomfort and palpitations...

BACKGROUND: The determinants and prognostic value of albuminuria remain unclear in patients with adult congenital heart disease (ACHD), especially in those with Fontan circulation (FC). METHODS: We retrospectively reviewed 512 consecutive ACHD patients and investigated the determinants of urinary albumin-to-creatinine ratio (ACR) and albuminuria (MAU) and their association with all-cause mortality. Demographic data and laboratory and hemodynamic parameters were collected...

BACKGROUND: The exact interaction of factors leading to myocardial dysfunction and fibrosis of the systemic right ventricle (SRV) is not completely understood. Myocardial ischemia and injury associated with a supply-demand mismatch of the pressure overloaded SRV are thought to play an important role, however studies confirming this are lacking. METHODS: Adult SRV patients were included in this single centre cohort study. All patients underwent a comprehensive diagnostic and imaging workup...

BACKGROUND: Nowadays, more than 90% of patients with congenital heart disease (CHD) reach adulthood. However, long-term impact on neurodevelopment and executive functioning in adults with CHD are not completely understood. PURPOSE: To investigate the self- and informant-reported executive functioning in adults with CHD operated in childhood. MATERIAL AND METHODS: Longitudinal study of a cohort of patients (n = 194, median age: 49...

Baffle leaks are a frequently encountered and often overlooked complication after the atrial switch procedure for transposition of the great arteries. Baffle leaks are present in up to 50% of non-selected patients, and while they initially may not cause clear symptoms, they can complicate the hemodynamic course and influence the prognosis in this complex patient group. A shunt from the pulmonary venous atrium (PVA) to the systemic venous atrium (SVA) can lead to pulmonary overflow and subpulmonary left ventricular (LV) volume overload, while a shunt from the SVA to the PVA can result in (exercise-associated) cyanosis and paradoxical embolism...

BACKGROUND: The prognosis of patients with a functional single ventricle has improved, with better cardiopulmonary fitness, health-related quality of life and survival. Conventional echocardiography remains the first-line technique in single ventricle follow-up. Three-dimensional (3D) echocardiography has shown recent value in congenital cardiology, but its ability to predict functional status in patients with a single ventricle remains unknown. AIM: To evaluate, in patients with a single ventricle, the association between 3D echocardiography variables and functional status determined by cardiopulmonary fitness...

BACKGROUND: Heart failure (HF) is characterized by significant mortality in both adults and children. Characteristic of paediatric HF are feeding problems, poor weight gain, exercise intolerance or dyspnoea. These changes are often accompanied by endocrine disorders. The main causes of HF are congenital heart defects (CHD) cardiomyopathies, arrhythmias, myocarditis or heart failure secondary to oncological treatment. Heart transplantation (HTx) is the method of choice for treatment of end-stage HF in paediatric patients...

BACKGROUND: Little is known about how sport and school restrictions early during the novel coronavirus 2019 (COVID-19) pandemic impacted exercise performance and body composition in youth with heart disease (HD). METHODS: A retrospective chart review was performed on all patients with HD who had serial exercise testing and body composition via bioimpedance analysis performed within 12 months before and during the COVID-19 pandemic. Formal activity restriction was noted as present or absent...

In this manuscript, we describe the design and rationale of a randomized controlled trial in pediatric Fontan patients to test the hypothesis that a live-video-supervised exercise (aerobic+resistance) intervention will improve cardiac and physical capacity; muscle mass, strength, and function; and endothelial function. Survival of children with single ventricles beyond the neonatal period has increased dramatically with the staged Fontan palliation. Yet, long-term morbidity remains high. By age 40, 50% of Fontan patients will have died or undergone heart transplantation...

BACKGROUND: The cardiopulmonary exercise test is accepted as a helpful diagnostic tool in risk stratification, evaluation of prognosis, and guiding treatment modality in adults with congenital heart disease. In this study, we present our experience with the use of cardiopulmonary exercise test in children with congenital heart disease in different physiological and anatomical classifications. METHODS: In this retrospective study, 25 children and adolescents who applied to the pediatric cardiology outpatient clinic between 2017 and 2020 with the diagnosis of different types of congenital heart disease were included...

PURPOSE: Psychological distress and anxiety are increased among adults with congenital heart disease (CHD). However, heart-focused anxiety (HFA) and its impact on peak oxygen uptake (V˙O2peak) have not yet been studied in this patient cohort. This study investigates HFA in adults with CHD and whether HFA is associated with V˙O2peak in these patients. METHODS: In this cross-sectional study, HFA was assessed in 984 adults with various CHD (34.2 ± 11...

BACKGROUND: Exercise intolerance is a major manifestation of pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD). We aimed to investigate the characteristics of exercise intolerance in different subgroups of PAH-CHD. METHODS: We retrospectively enrolled 171 adult patients with PAH-CHD and 30 age and sex-matched healthy subjects and performed cardiopulmonary exercise testing. Gas exchange parameters, including peak oxygen uptake (peak V̇o2 ), anaerobic threshold, and the slope of ventilatory equivalent for carbon dioxide (V̇e/V̇co2 slope), were recorded...

To control the development of people with congenital heart disease (CHD), it is important to follow their aerobic capacity (AC), especially when they exercise. This research aimed to study the progress of AC during a follow-up of adults with CHD. This is a longitudinal study which involved 127 adults with a mean age of 33.8 (11.1) years (57.5% female; 75 moderate CHD and 52 complex CHD) who had undergone two cardiopulmonary exercise tests (CEPT) in at least one year between the first and the second test. The AC and exercise performance (EP) (duration of exercise time, velocity and percentage of grade) were assessed using a ramp protocol over a treadmill...

Oxidative stress is an important pathophysiological mechanism in the development of numerous cardiovascular disorders, but few studies have examined the levels of oxidative stress in adults with congenital heart disease (CHD). The objective of this study was to investigate oxidative stress levels in adults with CHD and the association with inflammation, exercise capacity and endothelial function. To this end, 36 adults with different types of CHD and 36 age- and gender-matched healthy controls were enrolled...

A scientific guideline has been developed to update and harmonize exercise based cardiac rehabilitation (CR) in German speaking countries of Europe. It addresses all aspects of CR including indications, contents and delivery. Four meta-analyses were performed to evaluate the prognostic effect of CR after acute coronary syndrome (ACS), after coronary bypass grafting (CABG), in patients with systolic heart failure (HFrEF), and to define the effect of psychological interventions during CR. Other indications for CR were based on a predefined semi-structured literature search and recommendations were established by a formal consenting process...
