RESUMEN
Background: As more women with congenital heart disease (CHD) are reaching childbearing age, it becomes more common for their symptoms to be evaluated during pregnancy. However, pregnancy-related symptoms are similar to those caused by heart disease. This study investigated the prevalence of factors associated with symptoms during pregnancy in women with CHD. Methods: The national birth register was searched for primiparous women with CHD who were registered in the national quality register for patients with CHD. Results: Symptoms during the third trimester were reported in 104 of 465 evaluated women. The most common symptom was palpitations followed by dyspnea. Factors associated with symptoms were tested in a univariable model; higher NYHA classification (>1) (OR 11.3, 95%CI 5.5-23.2), low physical activity (≤3 h/week) (OR 2.1 95%CI 1.3-3.6) and educational level ≤ 12 years (OR 1.9 95%CI 1.2-3.0) were associated with having symptoms. In multivariable analysis, low physical activity level (OR 2.4 95%CI 1.2-5.0) and higher NYHA class (OR 11.3 95%CI 5.0-25.6) remained associated with symptoms during pregnancy. There were no cases with new onset of impaired systemic ventricular function during pregnancy. Conclusion: Symptoms during pregnancy are common in women with CHD but are often already present before pregnancy. Because ordinary symptoms during pregnancy often overlap with symptoms of heart disease, it is important to know if symptoms were present before pregnancy and if they became worse during pregnancy. These results should be included in pre-pregnancy counselling and considered in the monitoring during pregnancy.

Background. Poor maternal self-rated health in healthy women is associated with adverse neonatal outcomes, but knowledge about self-rated health in pregnant women with congenital heart disease (CHD) is sparse. This study, therefore, investigated self-rated health before, during, and after pregnancy in women with CHD and factors associated with poor self-rated health. Methods. The Swedish national registers for CHD and pregnancy were merged and searched for primiparous women with data on self-rated health; 600 primiparous women with CHD and 3062 women in matched controls. Analysis was performed using descriptive statistics, chi-square test and logistic regression. Results. Women with CHD equally often rated their health as poor as the controls before (15.5% vs. 15.8%, p = .88), during (29.8% vs. 26.8% p = .13), and after pregnancy (18.8% vs. 17.6% p = .46). None of the factors related to heart disease were associated with poor self-rated health. Instead, factors associated with poor self-rated health during pregnancy in women with CHD were ≤12 years of education (OR 1.7, 95%CI 1.2-2.4) and self-reported history of psychiatric illness (OR 12.6, 95%CI 1.4-3.4). After pregnancy, solely self-reported history of psychiatric illness (OR 5.2, 95%CI 1.1-3.0) was associated with poor self-rated health. Conclusion. Women with CHD reported poor self-rated health comparable to controls before, during, and after pregnancy, and factors related to heart disease were not associated with poor self-rated health. Knowledge about self-rated health may guide professionals in reproductive counselling for women with CHD. Further research is required on how pregnancy affects self-rated health for the group in a long-term perspective.

OBJECTIVES: Implantable cardiac devices are common in patients with tetralogy of Fallot (ToF) (18.3-21.3%) according to previous reports from large centres. We conducted this study to investigate the prevalence and incidence of cardiac devices in a less selected population of patients with ToF and assess factors other than arrhythmia associated with having a device. Design: 530 adult (≥18 years) patients with repaired ToF were identified in the national registry of congenital heart disease (SWEDCON) and matched with data from the Swedish pacemaker registry. Patients with implantable cardiac devices were compared with patients without devices. Results: Seventy-five patients (14.2%) had a device; 51 (9.6%) had a pacemaker and 24 (4.5%) had an implantable cardioverter defibrillator. The incidence in adult age (≥18 years) was 5.9/1000 patient years. Estimated device free survival was 97.5% at twenty, 87.2% at forty and 63.5% at sixty years of age. Compared with previous studies, the prevalence of devices was lower, especially for ICD. In multivariate logistic regression, cardiovascular medication (odds ratio [OR] 3.5, 95% confidence interval [CI] 1.8-6.8), impaired left ventricular function, (OR 2.6, 95%CI 1.3-5.0) and age (OR 1.02, 95%CI 1.002-1.05) were associated with having a device. Conclusion: The prevalence of devices in our population, representing a multicenter register cohort, was lower than previously reported, especially regarding ICD. This can be due to differences in treatment traditions with regard to ICD in this population, but it may also be that previous studies have reported selected patients with more severe disease.

BACKGROUND: Patients with CHD exhibit reduced isometric muscle strength and muscle mass; however, little is known how these parameters relate. Therefore, the aim was to investigate the relation between isometric limb muscle strength and muscle mass for patients in comparison to age- and sex-matched control subjects. METHODS: Seventy-four patients (35.6 ± 14.3 years, women n = 22) and 74 matched controls were included. Isometric muscle strength in elbow flexion, knee extension, and hand grip was assessed using dynamometers. Lean mass, reflecting skeletal muscle mass, in the arms and legs was assessed with dual-energy x-ray absorptiometry. RESULTS: Compared to controls, patients had lower muscle strength in elbow flexion, knee extension, and hand grip, and lower muscle mass in the arms (6.6 ± 1.8 kg versus 5.8 ± 1.7 kg, p < 0.001) and legs (18.4 ± 3.5 kg versus 15.9 ± 3.2 kg, p < 0.001). There was no difference in achieved muscle force per unit muscle mass in patients compared to controls (elbow flexion 0.03 ± 0.004 versus 0.03 ± 0.005 N/g, p = 0.5; grip strength 0.008 ± 0.001 versus 0.008 ± 0.001 N/g, p = 0.7; knee extension 0.027 ± 0.06 versus 0.028 ± 0.06 N/g, p = 0.5). For both groups, muscle mass in the arms correlated strongly with muscle strength in elbow flexion (patients r = 0.86, controls, r = 0.89), hand grip (patients, r = 0.84, controls, r = 0.81), and muscle mass in the leg to knee extension (patients r = 0.64, controls r = 0.68). CONCLUSION: The relationship between isometric muscle strength and limb muscle mass in adults with CHD indicates that the skeletal muscles have the same efficiency as in healthy controls.

BACKGROUND: Ascending aortic dilation is a feared complication in adults with repaired coarctation of the aorta, as the condition is associated with life-threatening complications such as aortic dissection and rupture. However, the data are currently limited regarding factors associated with ascending aortic dilation in these patients. METHODS AND RESULTS: From the national register of congenital heart disease, 165 adult patients (≥ 18 years old) with repaired coarctation of the aorta, and echocardiographic data on aortic dimensions, were identified (61.2% male, mean age 35.8 ± 14.5 years). Aortic dilation (aortic diameters > 2 SD above reference mean) was found in 55 (33.3%) of the 165 included patients, and was associated with manifest aortic valve disease in univariable logistic regression analysis (OR 2.44, 95% CI [1.23, 4.83]). CONCLUSIONS: Aortic dilation is common post-repair of coarctation of the aorta, and is associated with manifest aortic valve disease and thus indirectly with the presence of a bicuspid aortic valve. However, no association was found between aortic dilation and age or blood pressure.

Objective: Congenitally corrected and surgical atrial redirected transposition of the great arteries (TGA) represents states where the morphological right ventricle serves as a systemic ventricle (S-RV). The S-RV is prone to failure, but data on medical treatment on this problem is limited. The purpose of this study was to evaluate the survival in adults with S-RV, with or without heart failure treatment. Design: The SWEDCON registry was used to collect data. All adults with S-RV and minimum follow-up of 1 year were included retrospectively. Medical treatment was defined as taking beta-blockers and/or ACE inhibitors and/or ARBs for more than 50% of the time. Results: We identified 343 patients with S-RV (median age: 21 years). Surgical atrial redirected TGA was present in 58% and congenitally corrected TGA in 42% of patients. The medically treated group (n = 126) had higher rates of impaired S-RV function, use of diuretics, pacemaker and higher NYHA functional class at baseline compared to controls. The proportion of patients with impaired functional class did not change over time in the medically treated group, but increased in controls (21% vs. 30%, p = .015). In Kaplan-Meier analysis, the mean follow-up was 10.3 years, no difference in survival was seen between the groups. Conclusions: Medical treatment may be beneficial in patients with S-RV and impaired functional class and appears to be safe in the long term. The treatment group had equal survival to controls, despite worse baseline characteristics, which might be a result of slower progression of disease in this group.

BACKGROUND: The aim of this retrospective study was to evaluate the relationship between right ventricular function derived from cardiac magnetic resonance imaging (CMR), echocardiography and exercise stress test performance, NT-proBNP (N-terminal proB-type natriuretic peptide) level and NYHA class in patients with a systemic right ventricle. METHODS: All patients with congenitally corrected transposition of the great arteries (ccTGA), or transposition of the great arteries after Mustard or Senning procedures, (TGA) followed at our centre who had undergone CMR, echocardiography, an exercise stress test and blood sampling, were included in the study. RESULTS: We examined 11 patients (six after the Senning procedure, one after the Mustard procedure, and four ccTGA) who have a median age of 32 years (22-67 years). A significant correlation was observed between the systemic ventricular function, expressed as the CMR-derived right ventricular ejection fraction and the right ventricular global longitudinal strain (r= -0.627; p=0.039). CONCLUSION: We have demonstrated that in patients with ccTGA or TGA right ventricular global longitudinal strain may be useful in the evaluation of the systemic right ventricular function.

BACKGROUND: Eisenmenger syndrome is associated with substantial morbidity and mortality. There is no consensus, however, on mortality risk stratification. We aimed to investigate survival and predictors of death in a large, contemporary cohort of Eisenmenger syndrome patients. METHODS: In a multicenter approach, we identified adults with Eisenmenger syndrome under follow-up between 2000 and 2015. We examined survival and its association with clinical, electrocardiographic, echocardiographic, and laboratory parameters. RESULTS: We studied 1098 patients (median age, 34.4 years; range, 16.1-84.4 years; 65.1% female; 31.9% with Down syndrome). The majority had a posttricuspid defect (n=643, 58.6%), followed by patients with a complex (n=315, 28.7%) and pretricuspid lesion (n=140, 12.7%). Over a median follow-up of 3.1 years (interquartile range, 1.4-5.9), allowing for 4361.6 patient-years observation, 278 patients died and 6 underwent transplantation. Twelve parameters emerged as significant predictors of death on univariable analysis. On multivariable Cox regression analysis, only age (hazard ratio [HR], 1.41/10 years; 95% confidence interval [CI], 1.24-1.59; P<0.001), pretricuspid shunt (HR, 1.56; 95% CI, 1.02-2.39; P=0.041), oxygen saturation at rest (HR, 0.53/10%; 95% CI, 0.43-0.65; P<0.001), presence of sinus rhythm (HR, 0.53; 95% CI, 0.32-0.88; P=0.013), and presence of pericardial effusion (HR, 2.41; 95% CI, 1.59-3.66; P<0.001) remained significant predictors of death. CONCLUSIONS: There is significant premature mortality among contemporary adults with Eisenmenger syndrome. We report, herewith, a multivariable mortality risk stratification model based on 5 simple, noninvasive predictors of death in this population.

AIMS: Eisenmenger syndrome (ES) is associated with considerable morbidity and mortality. Therapeutic strategies have changed during the 2000s in conjunction with an emphasis on specialist follow-up. The aim of this study was to determine the cause-specific mortality in ES and evaluate any relevant changes between 1977 and 2015. METHODS AND RESULTS: This is a retrospective, descriptive multicentre study. A total of 1546 patients (mean age 38.7 ± 15.4 years; 36% male) from 13 countries were included. Cause-specific mortality was examined before and after July 2006, 'early' and 'late', respectively. Over a median follow-up of 6.1 years (interquartile range 2.1-21.5 years) 558 deaths were recorded; cause-specific mortality was identified in 411 (74%) cases. Leading causes of death were heart failure (34%), infection (26%), sudden cardiac death (10%), thromboembolism (8%), haemorrhage (7%), and peri-procedural (7%). Heart failure deaths increased in the 'late' relative to the 'early' era (P = 0.032), whereas death from thromboembolic events and death in relation to cardiac and non-cardiac procedures decreased (P = 0.014, P = 0.014, P = 0.004, respectively). There was an increase in longevity in the 'late' vs. 'early' era (median survival 52.3 vs. 35.2 years, P < 0.001). CONCLUSION: The study shows that despite changes in therapy, care, and follow-up of ES in tertiary care centres, all-cause mortality including cardiac remains high. Patients from the 'late' era, however, die later and from chronic rather than acute cardiac causes, primarily heart failure, whereas peri-procedural and deaths due to haemoptysis have become less common. Lifelong vigilance in tertiary centres and further research for ES are clearly needed.

BACKGROUND: Reconstruction of the right ventricular outflow tract with a conduit is an established surgical procedure in congenital heart disease and reinterventions are common. OBJECTIVE: An increasing number of patients have a conduit, but there are few population-based studies of long-term outcomes after conduit surgery, reoperations, and transcatheter pulmonary valve replacement. METHODS: In April 2015, all adult patients with a conduit were identified in the Swedish National Registry for Congenital Heart Disease (SWEDCON). Data on patients who died before age of 16 years are not included in the registry and thus not included in the study. RESULTS: We found 574 patients with a mean age 36.1 years. The largest proportion had tetralogy of Fallot (45%). In total there were 762 operations and 50 transcatheter pulmonary valve replacements. Mean age at first conduit operation was 20.2 years. Long-term survival up to 48 years including perioperative mortality (<1%) was 93% at 20 years. The most common cause of death was cardiac-related. Higher age at first conduit operation was associated with increased mortality risk. Reintervention-free survival was 77% and 54% at 10 and 20 years, respectively. Conduit reinterventions were common. Ten-year reintervention-free survival after first conduit reintervention (n = 176) was significantly lower than after first conduit operation (70% vs 77% p = .04). Higher age at first conduit operation was associated with a reduced risk of reintervention, whereas male sex and complex malformations were associated with increased risk of reintervention. CONCLUSIONS: The mortality of repeated conduit reinterventions is low. The need for reintervention of conduits is considerable, and reintervention-free survival after the first conduit reintervention is poorer than after first conduit implantation. The findings in this study only applies for patients reaching 16 years of age.

OBJECTIVE: The use of a conduit is an established surgical method for reconstruction of the right ventricular outflow tract in congenital heart disease; however, its limited durability makes reintervention almost inevitable. We studied the trends in new implantation, reoperation, and transcatheter pulmonary valve replacement (TPVR) from a Swedish national perspective. DESIGN AND RESULTS: The Swedish registry of congenital heart disease (SWEDCON) was used to collect data. From 2000-2014, there was an increase in adult patients with conduits from 122 to 536. There were 60 surgical conduit replacements, 40 TPVRs and 176 new conduit implantations in the study period. Perioperative mortality was <1%. The yearly number of new implantations and reoperations both doubled over the study period. Patients with new implantations were older (mean age, 36 years) compared with the reoperation and TPVR groups (mean age, 26 years) with the majority of patients having tetralogy of Fallot. The majority of conduit reinterventions were surgical also after the introduction of TPVR in 2007, with no significant difference regarding diagnosis, gender, age, or previous number or longevity of conduits. CONCLUSION: The number of adults with conduits increased steadily with most conduit-related operations being new implantations in patients with tetralogy of Fallot. Surgical conduit replacements increased significantly and represented the majority of conduit reinterventions after the introduction of TPVR, indicating that TPVR is not used for the majority of patients with conduit failure. Diagnosis, gender, age, or previous number or longevity of conduits had no impact on choosing surgical replacement vs. TPVR.

BACKGROUND: Arterial hypertension is common in adults with repaired coarctation of the aorta, and is associated with several severe complications. Aims This study aimed to investigate the prevalence of poorly controlled (⩾140/90 mmHg) blood pressure among patients with diagnosed hypertension and to identify associated factors. METHODS: In the national register for CHD, adults with repaired coarctation of the aorta and diagnosed hypertension - defined as a registry diagnosis and/or use of anti-hypertensive prescription medication - were identified. Logistic regression analysis was used to identify variables associated with poorly controlled blood pressure. RESULTS: Of the 243 included patients, 27.2% were female, the mean age was 45.4±15.3 years, and 52.3% had poorly controlled blood pressure at the last registration. In a multivariable model, age (years) (OR 1.03, CI 1.01-1.06, p=0.008) was independently associated with poorly controlled blood pressure and so was systolic arm-leg blood pressure gradient in the ranges [10, 20] mmHg (OR 4.92, CI 1.76-13.79, p=0.002) to >20 mmHg (OR 9.93, CI 2.99-33.02, p<0.001), in comparison with the reference interval [0, 10] mmHg. Patients with poorly controlled blood pressure had, on average, more types of anti-hypertensive medication classes prescribed (1.9 versus 1.5, p=0.003). CONCLUSIONS: Poorly controlled blood pressure is common among patients with repaired coarctation of the aorta and diagnosed hypertension, despite what seems to be more intensive treatment. A systolic arm-leg blood pressure gradient is associated with poorly controlled blood pressure, even at low levels usually not considered for intervention, and may be an indicator of hypertension that is difficult to treat.

BACKGROUND: The atrial switch operation, the Mustard or Senning operation, for the transposition of the great arteries (TGA) was introduced in the late 1950s and was the preferred surgery for TGA until the early 1990s. The Mustard and Senning operation involves extensive surgery in the atria and leaves the right ventricle as the systemic ventricle. The Mustard and Senning cohort is now well into adulthood and we begin to see the long-term outcome. METHODS AND RESULTS: All the 6 surgical centers that performed Mustard and Senning operations in Sweden and Denmark identified all operated TGA patients. Information about death was obtained in late 2007 and early 2008 from the Danish and Swedish Centralised Civil Register by using the patients' unique national Civil Registration Numbers. Four hundred sixty-eight patients undergoing the atrial switch operation were identified. Perioperative 30-day mortality was 20%, and 60% were alive after 30 years of follow-up. Perioperative mortality was significantly increased by the presence of a ventricular septal defect, left ventricular outflow obstruction, surgery early in the Mustard and Senning era. However, only pacemaker implantation is predictive of long-term outcome (hazard ratio, 1.90; 95% confidence interval, 1.05-3.46, P=0.04), once the TGA patient has survived the perioperative period. The risk of reoperation was correlated to the presence of associated defects and where the first Mustard/Senning operation was performed. CONCLUSIONS: The long-term survival of patients with Mustard and Senning correction for TGA appears to be primarily determined by factors in the right ventricle and tricuspid valve and not the timing of or the type of surgery in childhood. Cardiac function necessitating the implantation of a pacemaker is associated with an increase in mortality.

AIMS: In adults with coarctation of the aorta (CoA), hypertension (HTN) is a common long-term complication. We investigated the prevalence of HTN and analyzed factors associated with HTN. METHODS AND RESULTS: In the national register for congenital heart disease, 653 adults with repaired CoA were identified (mean age 36.9±14.4years); 344 (52.7%) of them had HTN, defined as either an existing diagnosis or blood pressure (BP) ≥140/90mmHg at the clinical visit. In a multivariable model, age (years) (odds ratio [OR] 1.07, CI 1.05-1.10), sex (male) (OR 3.35, CI 1.98-5.68), and body mass index (kilograms per square meter) (OR 1.09, CI 1.03-1.16) were independently associated with having HTN, and so was systolic arm-leg BP gradient where an association with HTN was found at the ranges of (10, 20] and >20mmHg, in comparison to the interval ≤10mmHg (OR 3.58, CI 1.70-7.55, and OR 11.38, CI 4.03-32.11). This model remained valid when all patients who had increased BP (≥140/90mmHg) without having been diagnosed with HTN were excluded from the analyses. CONCLUSIONS: Hypertension is common in patients with previously repaired CoA and is associated with increasing age, male sex, and elevated body mass index. There is also an association with arm-leg BP gradient, starting at relatively low levels that are usually not considered for intervention.

BACKGROUND: The Fontan procedure has improved survival in children with functionally univentricular hearts. With time, however, complications such as reduced exercise capacity are seen more frequently. Exercise intolerance is multifactorial, but pulmonary vascular resistance probably plays a crucial role. Elevated pulmonary vascular resistance has been associated with raised levels of endothelin-1, which are common both before and after Fontan operations. Treatment with endothelin-1 receptor antagonists could theoretically improve cardiopulmonary hemodynamics and exercise capacity. The aim of this study was therefore to examine the efficacy and safety of bosentan in Fontan patients. METHODS AND RESULTS: Seventy-five adolescents and adults were randomized 1:1 to 14 weeks of treatment with bosentan or placebo. Cardiopulmonary exercise test, functional class, blood samples, and quality-of-life questionnaires were evaluated at baseline and at the end of treatment. Sixty-nine patients (92%) completed the study. Peak oxygen consumption increased 2.0 mL·kg(-1)·min(-1) (from 28.7 to 30.7 mL·kg(-1)·min(-1)) in the bosentan group compared with 0.6 mL·kg(-1)·min(-1) (from 28.4 to 29.0 mL·kg(-1)·min(-1)) in the placebo group (P=0.02). Cardiopulmonary exercise test time increased by 0.48 minute (from 6.79 to 7.27 minutes) versus 0.08 minute (from 6.94 to 7.02 minutes; P=0.04). Nine bosentan-treated patients improved 1 functional class, whereas none improved in the placebo group (P=0.0085). Side effects were mild and occurred equally in both groups. No serious adverse effects were seen, and no patients had liver enzyme levels above the 3-fold upper limit. CONCLUSIONS: Bosentan improves exercise capacity, exercise time, and functional class in Fontan patients without serious adverse events or hepatotoxicity.

AIMS: To describe the outcome of pregnancy in patients with structural or ischaemic heart disease. METHODS AND RESULTS: In 2007, the European Registry on Pregnancy and Heart disease was initiated by the European Society of Cardiology. Consecutive patients with valvular heart disease, congenital heart disease, ischaemic heart disease (IHD), or cardiomyopathy (CMP) presenting with pregnancy were enrolled. Data for the normal population were derived from the literature. Sixty hospitals in 28 countries enrolled 1321 pregnant women between 2007 and 2011. Median maternal age was 30 years (range 16-53). Most patients were in NYHA class I (72%). Congenital heart disease (66%) was most prevalent, followed by valvular heart disease 25%, CMP 7%, and IHD in 2%. Maternal death occurred in 1%, compared with 0.007% in the normal population. Highest maternal mortality was found in patients with CMP. During pregnancy, 338 patients (26%) were hospitalized, 133 for heart failure. Caesarean section was performed in 41%. Foetal mortality occurred in 1.7% and neonatal mortality in 0.6%, both higher than in the normal population. Median duration of pregnancy was 38 weeks (range 24-42) and median birth weight 3010 g (range 300-4850). In centres of developing countries, maternal and foetal mortality was higher than in centres of developed countries (3.9 vs. 0.6%, P < 0.001 and 6.5 vs. 0.9% P < 0.001) CONCLUSION: The vast majority of patients can go safely through pregnancy and delivery as long as adequate pre-pregnancy evaluation and specialized high-quality care during pregnancy and delivery are available. Pregnancy outcomes were markedly worse in patients with CMP and in developing countries.

OBJECTIVE: To investigate the time to first childbirth and to compare the prevalence of assisted reproductive treatment (ART) in women with congenital heart disease (CHD) compared with women without CHD. METHODS: All women in the national register for CHD who had a registered first childbirth in the Swedish Pregnancy Register between 2014 and 2019 were identified. These individuals (cases) were matched by birth year and municipality to women without CHD (controls) in a 1:5 ratio. The time from the 18th birthday to the first childbirth and the prevalence of ART was compared between cases and controls. RESULTS: 830 first childbirths in cases were identified and compared with 4137 controls. Cases were slightly older at the time for first childbirth (28.9 vs 28.5 years, p=0.04) and ART was more common (6.1% vs 4.0%, p<0.01) compared with controls. There were no differences in ART when stratifying for the complexity of CHD. For all women, higher age was associated with ART treatment (OR 1.24, 95% CI 1.20 to 1.28). CONCLUSIONS: Women with and without CHD who gave birth to a first child did so at similar ages. ART was more common in women with CHD, but disease severity did not influence the need for ART. Age was an important risk factor for ART also in women with CHD and should be considered in consultations with these patients.

BACKGROUND: The number of pregnant women with congenital heart disease (CHD) is rising, and the disease poses increased risks of cardiovascular and obstetric complications during pregnancy, potentially impacting breastfeeding success. This study aimed to investigate breastfeeding in primiparous women with CHD compared to primiparous women without CHD, and to examine potential hindering factors for breastfeeding in women with CHD. METHODS: The data were gathered between 2014 and 2019 and obtained by merging the Swedish Congenital Heart Disease Register (SWEDCON) with the Swedish Pregnancy Register. Primiparous women ≥ 18 years of age with CHD (n = 578) were matched by age and municipality to 3049 women without CHD, giving birth after 22 gestational weeks. Multivariable logistic regression analysis was used to identify factors associated with non-breastfeeding in women with CHD. RESULTS: Fewer women with CHD breastfed than women without CHD two days (94% vs. 97%, p = 0.001) and four weeks after birth (84% vs. 89%, p = 0.006). When all women were analysed, having CHD was associated with non-breastfeeding at both two days and four weeks after birth. For women with CHD, body mass index (BMI) ≥ 30 (OR 3.1; 95% CI 1.4, 7.3), preterm birth (OR 6.4; 95% CI 2.1, 19.0), self-reported history of psychiatric illness (OR 2.4; 95% CI 1.2, 5.1), small for gestational age (OR 4.2; 95% CI 1.4, 12.2), and New York Heart Association Stages of Heart Failure class II - III (OR 6.0; 95% CI 1.4, 26.7) were associated with non-breastfeeding two days after birth. Four weeks after birth, factors associated with non-breastfeeding were BMI ≥ 30 (OR 4.3; 95% CI 2.1, 9.0), self-reported history of psychiatric illness (OR 2.2; 95% CI 1.2, 4.2), and preterm birth (OR 8.9; 95% CI 2.8, 27.9). CONCLUSIONS: The study shows that most women with CHD breastfeed, however, at a slightly lower proportion compared to women without CHD. In addition, factors related to the heart disease were not associated with non-breastfeeding four weeks after birth. Since preterm birth, BMI ≥ 30, and psychiatric illness are associated with non-breastfeeding, healthcare professionals should provide greater support to women with CHD having these conditions.

Background: An association between impaired exercise capacity and risk of mortality has been reported among adults with congenital heart disease (CHD). Over the years, treatment methods have improved and may influence outcome. Hence, we report data from a national cohort reflecting a contemporary population. Objectives: The purpose of this study was to investigate the association between exercise capacity (workload) and mortality in a large registry-based cohort. Methods: Data on exercise capacity using cycle ergometer were retrieved from the national registry of CHD. The association between predicted exercise capacity (%ECpred) and mortality was analyzed using Cox regression. Results: In total, 3,721 adults (>18 years, 44.6% women) with CHD were included. The median age was 27.0 years (IQR: 20.8-41.0 years) and mean %ECpred was 77% ± 20%. Over a mean follow-up of 9.4 ± 6.0 years, there were 214 (5.8%) deaths. The Multivariable Cox regression model showed that moderately and severely impaired exercise capacity (50-<70 %ECpred: HR: 2.1, 95% CI: 1.4-3.2, P < 0.001, and <50 %ECpred: HR: 3.5, 95% CI: 2.1-6.0, P < 0.001) and CHD complexity were associated with higher mortality (moderate complexity: HR: 1.9 95% CI: 1.2-3.0, P = 0.003, great complexity: HR: 2.3 95% CI: 1.3-4.2, P = 0.008) when adjusted for New York Heart Association class, physical activity, cardiovascular medication, sex, impaired systemic ventricular function, and age. Conclusions: Impaired exercise capacity and CHD complexity are independently associated with all-cause mortality in patients with CHD. Exercise capacity is an easily accessible variable that may be a useful tool for risk assessment in adult patients with CHD, but this needs confirmation in prospective studies.
RESUMEN
Background Coarctation of the aorta coexists with other cardiac anomalies and has long-term complications, including recoarctation, which may require intervention after the primary coarctation repair. This study aims to clarify the prevalence of and risk factors for interventions related to the coarctation complex as well as late mortality in a large contemporary patient population. Methods and Results The Swedish National Register of Congenital Heart Disease was used, which comprised 683 adults with repaired coarctation of the aorta. Analysis was performed on freedom from intervention thereafter at the coarctation site, aortic valve, left ventricular outflow tract, or ascending aorta. One hundred ninety-six (29%) patients had at least 1 of these interventions. Estimated freedom from either of these interventions was 60% after 50 years. The risk of undergoing such an intervention was higher among men (hazard ratio, 1.6 [95% CI, 1.2-2.2]). Estimated freedom from another intervention at the coarctation site was 75% after 50 years. In women, there was an increase in interventions at the coarctation site after 45 years. Patients who underwent one of the previously mentioned interventions after the primary coarctation repair had poorer left ventricular function. Eighteen patients (3%) died during follow-up in the register. The standardized mortality ratio was 2.9 (95% CI, 1.7-4.3). Conclusions Interventions are common after coarctation repair. The risk for and time of interventions are affected by sex. Our results have implications for planning follow-up and giving appropriate medical advice to the growing population of adults with repaired coarctation of the aorta.
