Background: Scientific research regarding male-female differences in ascending aortic surgery is scarce. The objective of this study was to identify male-female differences in presentation, treatment and peri-operative outcome in elective ascending aortic surgery., Methods: Elective ascending aortic surgery procedures that took place in the Netherlands between 01/01/2013-31/12/2017 were identified from the Netherlands Heart Registration. Male-female differences in presentation, treatment characteristics, and in-hospital mortality and morbidity were explored., Results: The study population consisted of 887 females (31%) and 1,972 males (69%). Females were older (median age 67 versus 62 years, P<0.001), more often had chronic lung disease (12.3% versus 9.1%, P=0.011), New York Heart Association (NYHA) class III-IV (21.5% versus 15.5%, P=0.003), and less often a history of percutaneous coronary intervention (PCI) (3.2% versus 5.0%, P=0.033). Isolated supracoronary aortic replacement was performed in 47.7% of females versus 30.6% of males (P<0.001), and ascending aorta with root replacement in 40.6% of females versus 56.7% of males (P<0.001). Females more often underwent concomitant interventions of the aortic arch (33.1% versus 20.2%, P<0.001) and the mitral valve (8.2% versus 5.2%, P=0.002), and less often concomitant coronary artery bypass grafting (CABG) (14.4% versus 19.1%, P=0.002). Overall, in-hospital mortality was significantly higher in females (5.1% versus 2.7%, P=0.003). In multivariable regression analysis, being female was an independent risk factor for in-hospital mortality [odds ratio (OR) 1.55, 95% confidence interval (CI): 1.02-2.37]., Conclusions: This nation-wide cohort shows clear differences between females and males in patient presentation, procedural characteristics, in-hospital outcomes, and risk factors for in-hospital mortality in elective ascending aortic surgery. Further exploration of these differences, and of modifiable within-male and within-female risk factors, may offer great opportunities in improving treatment and thereby outcomes for both males and females., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2023 Annals of Cardiothoracic Surgery.

Objective: Acute type B aortic dissection (ATBD) is a rare yet serious cardiovascular event that potentially has an impact on health related quality of life (HRQoL). However, long term follow up data on this topic are scarce. This study aimed to review the long term HRQoL among patients treated for ATBD., Methods: In this multicentre, cross sectional survey study, consecutive treated patients with ATBD between 2007 and 2017 in four referral centres in the Netherlands were retrospectively included and baseline data were collected. Between 2019 and 2021 the 36 Item Short Form Survey (SF-36) was sent to all surviving patients (n = 263) and was compared with validated SF-36 scores in the Dutch general population stratified by age and sex., Results: In total, 144 of 263 surviving patients completed the SF-36 (response rate 55%). Median (IQR) age was 68 (61, 76) years at completion of the questionnaire, and 40% (n = 58) were female. Initial treatment was medical in 55% (n = 79), endovascular in 41% (n = 59), and surgical in 4% (n = 6) of ATBD patients. Median follow up time was 6.1 (range 1.7-13.9; IQR 4.0, 9.0) years. Compared with the general population, patients scored significantly worse on six of eight SF-36 subdomains, particularly physical domains. Apart from bodily pain, there were no substantial differences in HRQoL between male and female ATBD patients. Compared with sex matched normative data, females scored significantly worse on five of eight subdomains, whereas males scored significantly lower on six subdomains. Younger patients aged 41-60 years seemed more severely impaired in HRQoL compared with the age matched general population. Treatment strategy did not influence HRQoL outcomes. Follow up time was associated with better Physical and Mental Component Summary scores., Conclusion: Long term HRQoL was impaired in ATBD patients compared with the Dutch general population, especially regarding physical status. This warrants more attention for HRQoL during clinical follow up. Rehabilitation programmes including exercise and physical support might improve HRQoL and increase patients' health understanding., (Copyright © 2023 The Author(s). Published by Elsevier B.V.

Background: Biomarkers might help to improve diagnosis, surveillance and risk stratification of thoracic aortic disease (TAD). We explored the association between a broad spectrum of cardiovascular biomarkers with clinical characteristics and thoracic aortic diameter in TAD patients., Methods: Venous blood-samples were obtained in 158 clinically stable TAD patients visiting our outpatient clinic (2017-2020). TAD was defined as a thoracic aortic diameter ≥ 40 mm, or genetic confirmation (hereditary TAD). The cardiovascular panel III of the Olink multiplex platform was used for batch analysis of 92 proteins. A comparison was made between biomarker levels in patients with and without previous aortic dissection and/or surgery, and with and without hereditary TAD. Linear regression analyses were applied to identify (relative, normalized) biomarker concentrations associated with the absolute thoracic aortic diameter (AD max ), and thoracic aortic diameter indexed for body surface area (ID max )., Results: Median age of study patients was 61.0 (IQR 50.3-68.8) years, 37.3% females. Mean AD max and ID max were 43.3 ± 5.4 mm and 21.3 ± 3.3 mm/m 2 . After multivariable adjustment, Matrix Metalloproteinase-3 (MMP-3) and Insulin-like growth factor binding protein 2 (IGFBP-2) showed a significant positive association with AD max and ID max , respectively. Patients with previous aortic surgery/dissection had higher N-terminal-pro hormone BNP (NTproBNP) (median 3.67 [IQR 3.01-3.99] vs 2.84 [2.32-3.26], p ≤0.001). Patients with hereditary TAD had higher Trem-like transcript protein 2 (TLT-2) (median 4.64 [IQR 4.45-4.84]) than those with non-heriditary TAD (4.40 [4.17-4.64]; p = 0.00042)., Conclusions: Among a broad range of biomarkers, MMP-3 and IGFBP-2 were associated with disease severity in TAD patients. The pathophysiological pathways uncovered by these biomarkers, and their potential clinical use warrants further research., Competing Interests: Declaration of Competing Interest Authors Carlijn Thijssen, Silvy Dekker, Lidia Bons, Laurie Geenen, Arjen Gökalp, Johanna Takkenberg, Mostafa Mokhles, Jos Bekkers, Elke Bouwens, Eric Boersma, Roland van Kimmenade and Jolien Roos-Hesselink declare that they have no conflict of interest., (Copyright © 2023 The Author(s).

The aim of this article is to describe neurovascular findings in patients with Loeys Dietz syndrome type III and their possible clinical impact. Loeys Dietz syndrome type III, caused by pathogenic SMAD3 variants, is an autosomal dominant syndrome characterized by aneurysms and arterial tortuosity in combination with osteoarthritis. Neurovascular abnormalities have been described in other heritable aortic syndromes, however, reliable data in Loeys Dietz syndrome type III is missing. In our tertiary center, all adult patients with confirmed Loeys Dietz syndrome type III are followed in a standardized aorta outpatient clinic including Computed Tomography Angiography (CTA) of the head and neck region at baseline and (tri) yearly during follow-up. We performed an analysis of the neurovascular imaging findings and clinical follow-up. The primary outcome was a combined endpoint of mortality, dissection, cerebral vascular event and intervention. In addition, tortuosity and vascular growth were assessed. In total 26 patients (mean age 38.4 years, 38.5% males) underwent 102 (mean 3.9 (1-8) per patient) neurovascular Computed Tomography Angiography scans between 2010 and 2021. In 84.6% some form of neurovascular abnormality was found. The abnormalities at baseline were aneurysm (26.9%) dissection flap (7.7%), arterial tortuosity (61.5%), arterial coiling (23.1%) and arterial kinking (3.8%). During follow up (mean 8.85 (1-11) years) one patient suffered from sudden death and one patient needed a neuro-radiological intervention. No cerebral bleeding or stroke occurred. In conclusion, neurovascular imaging in Loeys Dietz syndrome type III patients revealed abnormalities such as aneurysm, tortuosity, coiling and kinking in the vast majority of patients, but clinical events were rare. Neurovascular screening and follow up is advised in all Loeys Dietz syndrome type III patients., (Copyright © 2022 The Authors. Published by Elsevier Masson SAS.. All rights reserved.)

Background: Although the descending aortic diameter is larger in smokers, data about thoracic aortic growth is missing. Our aim is to present the distribution of thoracic aortic growth in smokers and to compare it with literature of the general population., Methods: Current and ex-smokers aged 50-70 years from the longitudinal Danish Lung Cancer Screening Trial, were included. Mean and 95th percentile of annual aortic growth of the ascending aortic (AA) and descending aortic (DA) diameters were calculated with the first and last non-contrast computed tomography scans during follow-up. Determinants of change in aortic diameter over time were investigated with linear mixed models., Results: A total of 1987 participants (56% male, mean age 57.4 ± 4.8 years) were included. During a median follow-up of 48 months, mean AA and DA growth rates were comparable between males (AA 0.12 ± 0.31 mm/year and DA 0.10 ± 0.30 mm/year) and females (AA 0.11 ± 0.29 mm/year and DA 0.13 ± 0.27 mm/year). The 95th percentile ranged from 0.42 to 0.47 mm/year, depending on sex and location. Aortic growth was comparable between current and ex-smokers and aortic growth was not associated with pack-years. Our findings are consistent with aortic growth rates of 0.08 to 0.17 mm/years in the general population. Larger aortic growth was associated with lower age, increased height, absence of medication for hypertension or hypercholesterolemia and lower Agatston scores., Conclusions: This longitudinal study of smokers in the age range of 50-70 years shows that ascending and descending aortic growth is approximately 0.1 mm/year and is consistent with growth in the general population., (Copyright © 2019 Elsevier B.V.
