- Background: Atrial septal defect (ASD) is a congenital heart lesion that often remains undiagnosed until adulthood. The reasons for this may be multifactorial. It is, however, known that closure of a hemodynamically significant ASD improves exercise capacity. This study aimed to explore whether the aerobic capacity in late adolescence is associated with time to diagnosis and intervention in adult men with late diagnosis of an atrial shunt.Methods: The Swedish Military Conscription Service Register contains data on exercise tests performed in late adolescence. By linking these data with the National Patient Register, 254 men with a later intervention for an ASD were identified.Results: Interventions were performed at a mean of 26.5 +/- 7.9 years after the initial exercise tests. The mean absolute workload among those with a later diagnosed ASD was similar to those without a later diagnosed ASD (274 +/- 51W vs. 276 +/- 52 W, p = 0.49). Men with a higher exercise capacity (>= 1 SD) had their intervention earlier (21.9 +/- 8.6 years vs. 27.5 +/- 7.4 years, p < 0.001).Conclusions: The aerobic exercise capacity was similar in adolescent men with later interventions for ASD compared to the reference population. Furthermore, those with high exercise capacity appeared to be diagnosed earlier. Thus, low exercise capacity may not be a feature of ASD during adolescence, but rather develop later in life as a natural progression of the disease.

- 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.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background Coarctation of the aorta (CoA) constitutes 5-8 % of all congenital heart disease (CHD) and is associated with long-term complications such as hypertension (HTN) and left ventricular hypertrophy (LVH). Factors associated with HTN, LVH, and diffuse myocardial fibrosis, are not yet fully explored in this population.Methods Papers I-III: The Swedish national register of congenital heart disease (SWEDCON) was used to identify adult patients with repaired CoA.Paper IV: Data on 2,424 adult patients with CHD was extracted from SWEDCON and compared to controls (n = 4,605) regarding height, weight and body mass index (BMI).Paper V: Adults with CoA (n = 21, age 28.5 (19.1-65.1) years, 33.3 % female) referred for CMR were investigated with T1 mapping to determine left ventricular extracellular volume fraction (ECV).Results Papers I-II: Out of 653 patients, 344 (52.7 %) had HTN. In a multivariable model, age (years) (OR 1.07, CI 1.05-1.10), sex (male) (OR 3.35, CI 1.98-5.68) and BMI (kg/m2) (OR 1.09, CI 1.03-1.16) were associated with having HTN, and so was systolic arm-leg blood pressure (BP) gradient where an association was found at the ranges (10, 20] mmHg (OR 3.58, CI 1.70-7.55) and > 20 mmHg (OR 11.38, CI 4.03-32.11), in comparison to the range [0, 10] mmHg.When investigating 243 patients with diagnosed HTN, 127 (52.3 %) had elevated BP (≥ 140/90 mmHg). Age (years) (OR 1.03, CI 1.01-1.06) was associated with elevated BP, and so was systolic arm-leg BP gradient in the ranges (10, 20] mmHg (OR 4.92, CI 1.76-13.79), and > 20 mmHg (OR 9.93, CI 2.99-33.02), in comparison to the reference interval [0, 10] mmHg.Patients with elevated BP had more classes of anti-hypertensive medication classes prescribed (1.9 vs 1.5, p = 0.003).Paper III: Out of 506 patients, 114 (22.5 %) were found to have LVH. Systolic BP (mmHg) (OR 1.02, CI 1.01-1.04), aortic valve disease, (OR 2.17, CI 1.33–3.53), age (years) (OR 1.03, CI 1.01–1.05), and HTN (OR 3.02, CI 1.81-5.02), were associated with LVH, while sex (female) (OR 0.41, CI 0.24-0.72) was negatively associated with LVH.Paper IV: There was no difference in height, weight, or BMI between patients with CoA (n = 414) and the reference population.Paper V: In the population of 21 patients, an increased left ventricular myocardial ECV was found in 6 cases (28.6 %). Of the patients with increased ECV, 5/6 (83.3 %) were female (p = 0.002). Patients with increased ECV did not otherwise differ from the rest of the study population. ivConclusions In adults with repaired CoA, HTN and LVH were common, and many patients with HTN had elevated BP despite treatment. The potentially modifiable factors BMI and systolic arm-leg BP gradient were associated with HTN, and the gradient was also associated with elevated BP among patients with diagnosed HTN. The gradient’s significance remained even within what the current guidelines consider acceptable ranges. Potentially modifiable factors associated with LVH were systolic BP and aortic valve disease. We found no general difference in height, weight, or BMI between patients with CoA and the reference population. While LVH was more common among men, increased myocardial ECV was more common among women.

- 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. © 2021 The Author(s),. Published by Cambridge University Press.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Left ventricular hypertrophy (LVH) is common among patients with coarctation of the aorta (CoA). Cardiovascular magnetic resonance imaging (CMR) can be used to accurately measure left ventricular mass (LVM), but also the myocardial extracellular volume fraction (ECV), which reflects the degree of diffuse myocardial fibrosis.Aims: This study aimed to investigate the prevalence of increased left ventricular myocardial ECV in adults with CoA, and to assess the relationship between increased ECV and LVH.Material and methods: Adult patients with CoA (n = 21, age 28.5 (19.1-65.1) years, 33% female, 86% with prior CoA repair) referred clinically for CMR were investigated with T1 and ECV mapping. Clinical and echocardiographic data were retrieved from medical records.Results: Median ECV was 29.0 (22.0-35.0) %; 29.0 (22.0-33.0) % for men versus 32.0 (27.0-35.0) % for women, p = 0.026). Median LVM indexed to body surface area (BSA) was 71.5 (44.0-99.6) g/m2, and LVM/BSA did not correlate with ECV (r = -0.184, p = 0.450). An increased myocardial ECV exceeding the upper normal limit (30.6 %) was found in 6/21 (29 %) of the patients. Of the patients with increased ECV, 5/6 (83 %) were female (p = 0.002). Patients with increased ECV did not differ from the rest of the study population in terms of age, age at intervention, blood pressure, or functional parameters such as left ventricular volumes or ejection fraction (p > 0.05 for all).Conclusion: In a clinical population of adults with CoA, increased myocardial ECV was common, and associated with female sex, but not with LVM.

- 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. © 2016

- Background: Arterial hypertension is common in adults with repaired coarctation of the aorta (CoA). The associations between the diagnosis of hypertension, actual blood pressure, other factors affecting left ventricular overload, and left ventricular hypertrophy (LVH) are not yet fully explored in this population. Material and results: From the national register for congenital heart disease, 506 adult patients (>= 18 years old) with previous repair of CoA were identified (37.0% female, mean age 35.7 +/- 13.8 years, with an average of 26.8 +/- 12.4 years post repair). Echocardiographic data were available for all patients, and showed LVH in 114 (22.5%) of these. Systolic blood pressure (SBP) (mm Hg) (OR 1.02, CI 1.01-1.04), aortic valve disease, (OR 2.17, CI 1.33-3.53), age (years) (OR 1.03, CI 1.01-1.05), diagnosis of arterial hypertension (OR 3.02, CI 1.81-5.02), and sex (female) (OR 0.41, CI 0.24-0.72) were independently associated with LVH. There was an association with LVH at SBP within the upper reference limits [ 130, 140] mm Hg (OR 2.23, CI 1.05-4.73) that further increased for SBP > 140 mm Hg (OR 8.02, CI 3.76-17.12). Conclusions: LVH is common post repair of CoA and is associated with SBP even below the currently recommended target level. Lower target levels may therefore become justified in this population.

- Arterial hypertension is common in adults with repaired coarctation of the aorta, and is associated with several severe complications.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.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.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).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.
