RESUMEN
BACKGROUND: Women with thoracic aortic aneurysms within the arch or descending thoracic aorta have poorer survival than men. Sex differences in relative thoracic aortic aneurysm size may account for some of the discrepancy. The aim of this study was to explore whether basing clinical management on aneurysm size index (maximum aneurysm diameter/body surface area) rather than aneurysm size can restore equality of survival by sex. METHODS: The Effective Treatments for Thoracic Aortic Aneurysms (ETTAA; ISRCTN04044627) study was a prospective, observational cohort study. Adults referred to National Health Service hospitals in England with new/existing arch or descending thoracic aorta aneurysms greater than or equal to 4 cm in diameter were followed from March 2014 to March 2022. Baseline characteristics and survival to intervention and overall were compared for men and women. Survival models were used to assess the association between all-cause survival and sex, with and without adjustment for aneurysm diameter or aneurysm size index. RESULTS: A total of 886 thoracic aortic aneurysm patients were recruited: 321 (36.2%) women and 565 (63.8%) men. The mean(s.d.) aneurysm diameter was the same for women and men (5.7(1.1) versus 5.7(1.2) cm respectively; P = 0.751), but the mean(s.d.) aneurysm size index was greater for women than for men (3.32(0.80) versus 2.83(0.63) respectively; P < 0.001). Women had significantly worse survival without intervention: 110 (34.3%) women and 135 (23.9%) men (log rank test, P < 0.001). All-cause mortality remained greater for women after adjustment for diameter (HR 1.65 (95% c.i. 1.35 to 2.02); P < 0.001), but was attenuated after adjustment for aneurysm size index (HR 1.11 (95% c.i. 0.89 to 1.38); P = 0.359). Similar results were found for all follow-up, with or without intervention, and findings were consistent for descending thoracic aorta aneurysms alone. CONCLUSION: Guidelines for referral to specialist services should consider including aneurysm size index rather than diameter to reduce inequity due to patient sex.

OBJECTIVES: To evaluate the impact of previous cardiac surgery (PCS) on clinical outcomes after reoperative extended arch repair for acute type A aortic dissection. METHODS: This study included 37 acute type A aortic dissection patients with PCS (PCS group) and 992 without PCS (no-PCS group). Propensity score-matching yielded a subgroup of 36 pairs (1:1). In-hospital outcomes and mid-term survival were compared between the 2 groups. RESULTS: The PCS group was older (56.7 ± 14.2 vs 52.2 ± 12.6 years, P = 0.036) and underwent a longer cardiopulmonary bypass (median, 212 vs 183 min, P < 0.001) compared with the no-PCS group. Operative death occurred in 88 (8.6%) patients, exhibiting no significant difference between groups (13.5% vs 8.4%, P = 0.237). Major postoperative morbidity was observed in 431 (41.9%) patients, also showing no difference between groups (45.9% vs 41.7%, P = 0.615). Moreover, the multivariable logistic regression analysis revealed that PCS was not significantly associated with operative mortality (adjusted odds ratio 2.58, 95% confidence interval 0.91-7.29, P = 0.075) or major morbidity (adjusted odds ratio 1.92, 95% confidence interval 0.88-4.18, P = 0.101). The 3-year cumulative survival rates were 71.1% for the PCS group and 83.9% for the no-PCS group (log-rank P = 0.071). Additionally, Cox regression indicated that PCS was not significantly associated with midterm mortality (adjusted hazard ratio 1.40, 95% confidence interval 0.44-4.41, P = 0.566). After matching, no significant differences were found between groups in terms of operative mortality (P > 0.999), major morbidity (P > 0.999) and midterm survival (P = 0.564). CONCLUSIONS: No significant differences were found between acute type A aortic dissection patients with PCS and those without PCS regarding in-hospital outcomes and midterm survival after extended arch repair.

BACKGROUND: The outcomes of Thoracic Endovascular Aortic Repair (TEVAR) vary depending on thoracic aortic pathologies, comorbidities. This study presents our comprehensive endovascular experience, focusing on exploring the outcome in long term follow-up. METHODS: From 2006 to 2018, we conducted TEVAR on 97 patients presenting with various aortic pathologies. This retrospective cohort study was designed primarily to assess graft durability and secondarily to evaluate mortality causes, complications, reinterventions, and the impact of comorbidities on survival using Kaplan-Meier and Cox regression analyses. RESULTS: The most common indication was thoracic aortic aneurysm (n = 52). Ten patients had aortic arch variations and anomalies, and the bovine arch was observed in eight patients. Endoleaks were the main complications encountered, and 10 of 15 endoleaks were type I endoleaks. There were 18 reinterventions; the most of which was TEVAR (n = 5). The overall mortality was 20 patients, with TEVAR-related causes accounting for 12 of these deaths, including intracranial bleeding in three patients. Multivariant Cox regression revealed chronic renal diseases (OR = 11.73; 95% CI: 2.04-67.2; p = 0.006), previous cardiac operation (OR = 14.26; 95% CI: 1.59-127.36; p = 0.01), and chronic obstructive pulmonary diseases (OR = 7.82; 95% CI: 1.43-42.78; p = 0.001) to be independent risk factors for 10-year survival. There was no significant difference in the survival curves of the various aortic pathologies. In the follow-up period, two non-symptomatic intragraft thromboses and one graft infection were found. CONCLUSION: Comorbidities can increase the risk of TEVAR-related mortality without significantly impacting endoleak rates. TEVAR is effective for severe aortic pathologies, though long-term graft durability may be compromised by its thrombosis and infection.

OBJECTIVES: The aim of this multicentre study was to demonstrate the safety and clinical performance of E-vita OPEN NEO Stent Graft System (Artivion, Inc.) in the treatment of aneurysm or dissection, both acute and chronic, in the ascending aorta, aortic arch and descending thoracic aorta. METHODS: In this observational study of 12 centres performed in Europe and in Asia patients were enrolled between December 2020 and March 2022. All patients underwent frozen elephant trunk using E-vita OPEN NEO Stent Graft System. Primary end point was the rate of all-cause mortality at 30 days and secondary end points included further clinical and safety data are reported up to 3-6 months postoperatively. RESULTS: A total of 100 patients (66.7% male; mean age, 57.7 years) were enrolled at 12 sites. A total of 99 patients underwent surgery using the E-vita OPEN NEO for acute or subacute type A aortic dissection (n = 37), chronic type A aortic dissection (n = 33) or thoracic aortic aneurysm (n = 29), while 1 patient did not undergo surgery. Device technical success at 24 h was achieved in 97.0%. At discharge, new disabling stroke occurred in 4.4%, while new paraplegia and new paraparesis was reported in 2.2% and 2.2%, respectively. Renal failure requiring permanent (>90 days) dialysis or hemofiltration at discharge was observed in 3.3% of patients. Between discharge and the 3-6 months visit, no patients experienced new disabling stroke, new paraplegia or new paraparesis. The 30-day mortality was 5.1% and the estimated 6-month survival rate was 91.6% (standard deviation: 2.9). CONCLUSIONS: Total arch replacement with the E-vita OPEN NEO can be performed with excellent results in both the acute and chronic setting. This indicates that E-vita OPEN NEO can be used safely, including in the setting of acute type A aortic dissection.

BACKGROUND: Women undergoing cardiac surgery have been historically recognized to carry higher periprocedural mortality risk. We aimed to investigate the influence of sex on clinical presentation, perioperative, and long-term outcomes in patients who undergo surgery for ascending aortic aneurysm. METHODS: We conducted a retrospective review of 1148 consecutive patients (380 [33.1%] female) who underwent thoracic aortic surgery under moderate hypothermic circulatory arrest for ascending aortic aneurysms between 2001 and 2021. Baseline and operative characteristics, in-hospital mortality, and survival were compared between male and female patients before and after propensity-score-matched (PSM) analysis. RESULTS: Women were significantly older (median age: 69 [IQR: 63-75] vs. 67 [IQR: 58-73]; P < 0.001), while men had a higher prevalence of aortic valve stenosis, bicuspid valve and coronary artery disease at the time of surgery (P < 0.05). After PSM, EuroSCORE II (4.36 [2.68; 6.87] vs. 3.22 [1.85; 5.31]; p < 0.001), and indexed aortic diameter were significantly higher in female patients (2.94 [2.68; 3.30] vs. 2.58 [2.38; 2.81] cm/m2, p < 0.001). In the matched cohort, men were more likely to experience postoperative delirium (18.1% vs. 11.5%; P = 0.002), and postoperative neurological deficits (6.7% vs. 3.0%, P = 0.044),. Female patients were more likely to receive postoperative packed red blood cells (p = 0.036) and fresh frozen plasma (p = 0.049). In-hospital and 30-day mortality was similar between both groups. Long-term survival was comparable between both groups with 88% vs. 88% at 5 years, 76% vs. 71% at 10 years, and 59% vs. 47% at 15 years. CONCLUSION: Female patients required more transfusions, while males had a higher incidence of postoperative delirium and neurological deficits. Differences in preoperative age and timing of surgery between the sexes could be attributed to variations in comorbidity profiles and the greater prevalence of concomitant surgery indications in males.

BACKGROUND: Stanford Type A Aortic Dissection (TAAD) is an emergent condition with high in-hospital mortality. Gender disparity in TAAD has been a topic of ongoing debate. This study aimed to conduct a population-based examination of gender disparities in short-term TAAD outcomes using the National/Nationwide Inpatient Sample (NIS) database, the largest all-payer database in the US. METHODS: Patients undergoing TAAD repair were identified in NIS from the last quarter of 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between male and female patients, adjusted for demographics, comorbidities, hospital characteristics, primary payer status, and transfer status. RESULTS: There were 1454 female and 2828 male patients identified who underwent TAAD repair. Female patients presented with TAAD were at a more advanced mean age (64.03 ± 13.81 vs. 58.28 ± 13.43 years, p < 0.01) and had greater comorbid burden. Compared to male patients, female patients had higher risks of in-hospital mortality (17.88% vs. 13.68%, adjusted odds ratio (aOR) = 1.266, p = 0.01). In addition, female patients had higher pericardial complications (20.29% vs. 17.22%, aOR = 1.227, p = 0.02), but lower acute kidney injury (AKI; 39.96% vs. 53.47%, aOR = 0.476, p < 0.01) and venous thromboembolism (VTE; 1.38% vs. 2.65%, aOR = 0.517, p = 0.01). Female patients had comparable time from admission to operation and transfer-in status, longer hospital stays, but fewer total hospital expenses. CONCLUSION: Female patients were 1.27 times as likely to die in-hospital after TAAD repair but had less AKI and VTE. While there is no evidence suggesting delay in TAAD repair for female patients, the disparities might stem from other differences such as in care provided or intrinsic physiological variations.

OBJECTIVES: Gender difference in the outcome after type A aortic dissection (TAAD) surgery remains an issue of ongoing debate. In this study, we aimed to evaluate the impact of gender on the short- and long-term outcome after surgery for TAAD. METHODS: A multicentre European registry retrospectively included all consecutive TAAD surgery patients between 2005 and 2021 from 18 hospitals across 8 European countries. Early and late mortality, and cumulative incidence of aortic reoperation were compared between genders. RESULTS: A total of 3902 patients underwent TAAD surgery, with 1185 (30.4%) being females. After propensity score matching, 766 pairs of males and females were compared. No statistical differences were detected in the early postoperative outcome between genders. Ten-year survival was comparable between genders (47.8% vs 47.1%; log-rank test, P = 0.679), as well as cumulative incidences of distal or proximal aortic reoperations. Ten-year relative survival compared to country-, year-, age- and sex-matched general population was higher among males (0.65) compared to females (0.58). The time-period subanalysis revealed advancements in surgical techniques in both genders over the years. However, an increase in stroke was observed over time for both populations, particularly among females. CONCLUSIONS: The past 16 years have witnessed marked advancements in surgical techniques for TAAD in both males and females, achieving comparable early and late mortality rates. Despite these findings, late relative survival was still in favour of males.

BACKGROUND: Fenestrated endovascular aortic aneurysm repair (FEVAR) has been widely applied for the treatment of pararenal (PAA) and thoracoabdominal aortic aneurysms (TAAA). If custom-made devices or off-the-shelf devices are not available, physician-modified endografts (PMEGs) are an alternative device option. Several different endograft platforms have been used for PMEG; however, minimal data exists on utilizing the Terumo TREO abdominal stent graft system in this setting. The purpose of this study was to evaluate our single-center experience treating PAA and TAAA, with a physician-modified FEVAR, using the Terumo TREO platform. METHODS: A prospective database of consecutive patients with PAA and TAAA treated at a single center, with a FEVAR, utilizing a PMEG device between March 2021 and September 2023 was queried for those having a Terumo TREO device implanted. The demographics, operative details, and postoperative complications were analyzed. The rates of technical success, type I or III endoleak, branch vessel status, reintervention, and 2-year survival were also assessed. RESULTS: Of the 153 patients who underwent FEVAR with a PMEG device during the study period, 100 had repair using a Terumo TREO stent graft. The mean age of the cohort was 73.7 ± 7.0 years with the majority suffering from hypertension (n = 94, 94%), coronary artery disease (n = 51, 51%), and chronic obstructive pulmonary disease (n = 40, 40%). Thirty-four patients (34%) had a prior failed EVAR device in place. The mean aneurysm size was 66.0 ± 13.7 mm, with 58 (50%) patients classified as PAA and 30 (30%) patients as an extent IV TAAA. Six (6%) patients presented with symptomatic/ruptured aneurysms. The average number of target arteries incorporated per patient was 3.8 ± 0.6. The overall technical success was 99%, procedure time was 218 ± 116 min, contrast volume was 82 ± 21 mL, and cumulative air kerma was 3,054 ± 1,560 mGy. Postoperative complications were present in 20 patients (20%), and 2 patients (2%) died within 30 days. Rates of type I or III endoleak, branch vessel stenosis or occlusion, and reintervention were 2%, 1%, and 7%, respectively. The two-year overall survival was 87%. CONCLUSIONS: Treatment of PAA and the extent IV TAAA using a physician-modified fenestrated Terumo TREO endograft is safe and effective. This large, early experience using the Terumo TREO platform supports preferential use of this device in this setting due to the device design and low likelihood of type I or III endoleak.

BACKGROUND: Acute type A aortic dissection is a dangerous disease that threatens public health. In recent years, with the progress of medical technology, the mortality rate of patients after surgery has been gradually reduced, leading that previous prediction models may not be suitable for nowadays. Therefore, the present study aims to find new independent risk factors for predicting in-hospital mortality and construct a nomogram prediction model. METHODS: The clinical data of 341 consecutive patients in our center from 2019 to 2023 were collected, and they were divided into two groups according to the death during hospitalization. The independent risk factors were analyzed by univariate and multivariate logistic regression, and the nomogram was constructed and verified based on these factors. RESULTS: age, preoperative lower limb ischemia, preoperative activated partial thromboplastin time (APTT), preoperative platelet count, Cardiopulmonary bypass (CPB) time and postoperative acute kidney injury (AKI) independently predicted in-hospital mortality of patients with acute type A aortic dissection after surgery. The area under the receiver operating characteristic curve (AUC) for the nomogram was 0.844. The calibration curve and decision curve analysis verified that the model had good quality. CONCLUSION: The new nomogram model has a good ability to predict the in-hospital mortality of patients with acute type A aortic dissection after surgery.

BACKGROUND: The operative outcomes of thoracoabdominal aortic aneurysms (TAAAs) are challenged by high operative mortality and disabling complications. This study aimed to explore the baseline clinical, anatomical, and procedural risk factors that impact early and late outcomes following open repair of TAAAs. METHODS: We reviewed the medical records of 290 patients who underwent open repair of TAAAs between 1992 and 2020 at a tertiary referral center. Determinants of early mortality (within 30 days or in hospital) were analyzed using multivariable logistic regression models, while those of overall follow-up mortality were explored using multivariable Cox proportional hazards models and landmark analyses. RESULTS: The rates of early mortality and spinal cord deficits were 13.1% and 11.0%, respectively, with Crawford extent II showing the highest rates. In the logistic regression models, older age (P < 0.001), high cardiopulmonary bypass (CPB) time (P < 0.001), and low surgical volume of the surgeon (P < 0.001) emerged as independent factors significantly associated with early mortality. During follow-up (median, 5.0 years; interquartile range, 1.1-7.6 years), 82 late deaths occurred (5.7%/patient-year). Cox proportional hazards models demonstrated that older age (P < 0.001) and low hemoglobin level (P = 0.032) were significant risk factors of overall mortality, while the landmark analyses revealed that the significant impacts of low surgical volume (P = 0.017), high CPB time (P = 0.002), and Crawford extent II (P = 0.017) on mortality only remained in the early postoperative period, without significant late impacts (all P > 0.05). CONCLUSION: There were differential temporal impacts of perioperative risk variables on mortality in open repair of TAAAs, with older age and low hemoglobin level having significant impacts throughout the postoperative period, and low surgical volume, high CPB time, and Crawford extent II having impacts in the early postoperative phase.

The age, creatinine, and ejection fraction (ACEF) score has been accepted as a predictor of poor outcome in elective operations. This study aimed to investigate the predictive value of ACEF score in acute type A aortic dissection (AAAD) patients after total arch replacement. A total of 227 AAAD patients from July 2021 and June 2022 were enrolled and divided into Tertiles 1 (ACEF ≤ 0.73), Tertiles 2 (0.73 < ACEF ≤ 0.95), and Tertiles 3 (ACEF > 0.95). Using inverse probability processing weighting (IPTW) to balance the baseline characteristics and compare the outcomes. Cox logistic regression was used to further evaluate the survival prediction ability of ACEF score. The in-hospital mortality was 9.8%. After IPTW, in the baseline characteristics reached an equilibrium, a higher ACEF score before operation still associated with higher in-hospital mortality. After 1 year follow-up, 184 patients (90.6%) survival. Multivariable analysis revealed that ACEF score (adjusted hazard ratio 1.68; 95% confidence interval 1.34-4.91; p = 0.036) and binary ACEF score (adjusted HR 2.26; 95% CI 1.82-6.20; p < 0.001) was independently associated with 1-year survival. In addition, net reclassification improvement (NRI) and integrated differentiation improvement (IDI) verified that the ACEF score and binary ACEF score is an accurate predictive tool in clinical settings. In conclusions, ACEF score could be considered as a useful tool to risk stratification in patients with AAAD before operation in daily clinical work.

BACKGROUND: This study aimed to assess the early- and mid-term outcomes of aortic root repair and replacement, and to provide evidence to improve root management in acute type A aortic dissection (AAAD). METHODS: This study enrolled 455 patients who underwent AAAD root repair (n = 307) or replacement (n = 148) between January 2016 and December 2017. Inverse probability of treatment weighting (IPTW) method was used to control for treatment selection bias. The primary outcomes were in-hospital mortality, mid-term survival, and proximal aortic reintervention. RESULTS: The success rate of root repair was 99.7%. The in-hospital mortality in the conservative root repair (CRR) and aggressive root replacement (ARR) were 8.1% and 10.8%. The median follow-up time was 67.76 months (IQR, 67-72 months). After adjusting for baseline factors, there was no significant differences in mid-term survival (p = .750) or the proximal aortic reintervention rate (p = .550) between the two groups. According to Cox analysis, age, hypertension, severe aortic regurgitation, CPB time, and concomitant CABG were all factors associated with mid-term mortality. Regarding reintervention, multivariate analysis identified renal insufficiency, bicuspid aortic valve, root diameter ≥ 45 mm, and severe aortic regurgitation as risk factors, while CRR did not increase the risk of reintervention. The subgroup analysis revealed heterogeneity in the effects of surgical treatment across diverse populations based on a variety of risk factors. CONCLUSIONS: For patients with AAAD, both CRR and ARR are appropriate operations with promising early and mid-term outcomes. The effects of treatment show heterogeneity across diverse populations based on various risk factors.

BACKGROUND: Extended aortic repair is considered a key issue for the long-term durability of surgery for DeBakey type 1 aortic dissection. The risk of aortic degeneration may be higher in young patients due to their long life expectancy. The early outcome and durability of aortic surgery in these patients were investigated in the present study. METHODS: The subjects of the present analysis were patients under 60 years old who underwent surgical repair for acute DeBakey type 1 aortic dissection at 18 cardiac surgery centres across Europe between 2005 and 2021. Patients underwent ascending aortic repair or total aortic arch repair using the conventional technique or the frozen elephant trunk technique. The primary outcome was 5-year cumulative incidence of reoperation on the distal aorta. RESULTS: Overall, 915 patients underwent surgical ascending aortic repair and 284 patients underwent surgical total aortic arch repair. The frozen elephant trunk procedure was performed in 128 patients. Among 245 propensity score-matched pairs, total aortic arch repair did not decrease the rate of distal aortic reoperation compared to ascending aortic repair (5-year cumulative incidence, 6.7% versus 6.7%, subdistributional hazard ratio 1.127, 95% c.i. 0.523 to 2.427). Total aortic arch repair increased the incidence of postoperative stroke/global brain ischaemia (25.7% versus 18.4%, P = 0.050) and dialysis (19.6% versus 12.7%, P = 0.003). Five-year mortality was comparable after ascending aortic repair and total aortic arch repair (22.8% versus 27.3%, P = 0.172). CONCLUSIONS: In patients under 60 years old with DeBakey type 1 aortic dissection, total aortic arch replacement compared with ascending aortic repair did not reduce the incidence of distal aortic operations at 5 years. When feasible, ascending aortic repair for DeBakey type 1 aortic dissection is associated with satisfactory early and mid-term outcomes.

OBJECTIVES: The goal of this multicentre retrospective cohort study was to evaluate technical success and early and late outcomes of thoracic endovascular repair (TEVAR) with grafts deployed upside down through antegrade access, to treat thoracic aortic diseases. METHODS: Antegrade TEVAR operations performed between January 2010 and December 2021 were collected and analysed. Both elective and urgent procedures were included. Exclusion criteria were endografts deployed in previous or concomitant surgical or endovascular repairs. RESULTS: Fourteen patients were enrolled; 13 were males (94%) with a mean age of 71 years (interquartile range 62; 78). Five patients underwent urgent procedures (2 ruptured aortas and 3 symptomatic patients). Indications for treatment were 8 (57%) aneurysms/pseudoaneurysms, 3 (21%) dissections and 3 (21%) penetrating aortic ulcers. Technical success was achieved in all procedures. Early mortality occurred in 4 (28%) cases, all urgent procedures. Median follow-up was 13 months (interquartile range 1; 44). Late deaths occurred in 2 (20%) patients, both operated on in elective settings. The first died at 19 months of aortic-related reintervention; the second died at 34 months of a non-aortic-related cause. Two patients (14%) underwent aortic-related reinterventions for late type I endoleak. The survival rate of those having the elective procedures was 100%, 84% and 67% at 12, 24 and 36 months, respectively. Freedom from reintervention was 92%, 56% and 56% at 12, 24 and 36 months, respectively. CONCLUSIONS: Antegrade TEVAR can seldom be considered an alternative when traditional retrograde approach is not feasible. Despite good technical success and few access-site complications, this study demonstrates high rates of late type I endoleak and aortic-related reinterventions.

INTRODUCTION: Thoracic endovascular aortic repair (TEVAR) has gained preference over open surgical repair (OSR) as the intervention of choice for patients with descending thoracic aortic aneurysm (DTA). This study aimed to compare the outcomes of patients with DTA undergoing OSR and TEVAR with contemporary findings. EVIDENCE ACQUISITION: A comprehensive search of MEDLINE and EMBASE databases was conducted to identify relevant randomized controlled trials or studies utilizing propensity-score analysis or reporting risk-adjusted outcomes. The search was performed up until March 2023. EVIDENCE SYNTHESIS: Eight studies met the inclusion criteria, including 4 studies using propensity-score matching and four studies reporting risk-adjusted outcomes, comprising 14,873 patients with DTA undergoing OSR (N.=10,882) and TEVAR (N.=3991). Operative mortality was similar between the two interventions (odds ratio 0.92, 95% CI 0.70-1.21, P=0.57, I2=0%). However, overall long-term mortality was significantly higher after TEVAR compared to OSR (Hazard Ratio [HR] 1.30, 95% CI 1.05-1.59, P=0.01, I2=0%). Phase-specific analysis revealed comparable risks of mortality within 1 year and between one and two years after interventions, while the risk of mortality was significantly higher after TEVAR compared to OSR beyond two years (HR 1.77, 95% CI, 1.19-2.63, P=0.01. I2=0%). CONCLUSIONS: This study demonstrated comparable operative mortality between OSR and TEVAR, but higher long-term mortality associated with TEVAR in patients with DTA. The phase-specific analysis highlighted the survival advantage of OSR beyond 2 years. These findings suggest a need for reconsidering OSR indications in the management of DTA.

PURPOSE: Thoracic aortic dissection (TAD) is a life-threatening cardiovascular disease that often results in sudden cardiac death (SCD). However, the genetic characteristics of individuals with TAD confirmed at autopsy have been rarely studied. Our objective was to determine the prevalence of pathogenic variants in TAD-associated genes in a cohort of sporadic deaths resulting from spontaneous rupture of TAD and identify relevant genotype-phenotype relationships in Han Chinese population. METHODS: We included sixty-one consecutive sporadic decedents whose primary cause of death was spontaneous rupture of TAD, and performed a whole exome sequencing based strategy comprising 26 known TAD-associated genes. RESULTS: We identified 7 pathogenic or likely pathogenic (P/LP) variants in 7 cases (11.48â¯%) and 22 variants of uncertain significance (VUS) in 22 cases (36.07â¯%). The FBN1 gene was found to be the major disease-causing gene. Notably, TAD decedents with P/LP variant exhibited significantly earlier mortality. Moreover, we reported for the first time that TAD decedents with P/LP variant had a shorter diagnosis and treatment time. CONCLUSION: Our study investigated the genetic characteristics of TAD individuals confirmed until autopsy in Han Chinese population. The findings enhanced the understanding of the genetic underpinnings of TAD and have significant implications for clinical management and forensic investigations.

OBJECTIVE: This study aimed to compare two commercially available off the shelf branched endografts for thoraco-abdominal aortic aneurysm (TAAA) repair, namely the E-nside (Artivion) and Zenith t-Branch (Cook Medical) devices. METHODS: This multicentre retrospective study (2020 - 2023) included patients treated by branched endovascular aortic repair (BEVAR) for TAAA using the inner branched E-nside or the outer branched t-Branch. Endpoints were 30 day technical success and major adverse events (MAEs) as well as one year freedom from target vessel instability and main endograft instability. RESULTS: The study included 163 patients: 79 (307 target vessels) treated with E-nside and 84 (325 target vessels) with t-branch. Aneurysm extent was I - III in 91 patients (55.8%; 47% of E-nside and 66% of t-Branch) and IV in 72 patients (44.2%; 53% of E-nside and 34% of t-Branch) (p = .011). An adjunctive proximal thoracic endograft was used in 43% of E-nside vs. 69% of t-Branch (p < .001), with less frequent thoracic endografting (14% vs. 76%; p < .001) and shorter length of coverage (p = .024) in extent IV TAAA treated by E-nside. E-nside cases had shorter renal artery bridging lengths (66 ± 17 mm vs. 76 ± 20 mm; p < .010) and less frequent use of a distal bifurcated endograft (53% vs. 80%; p < .001). Comparing 30 day results, the mortality rate was 1% vs. 2% (p = .62), any MAE occurred in 18% vs. 21% (p = .55), the stroke rate was 3% vs. 0% (p = .23), and the elective spinal cord ischaemia rate was 5% vs. 8% (p = .40) for E-nside and t-Branch, respectively. At one year, freedom from target vessel instability was 96 ± 3% for E-nside and 95 ± 3% for t-Branch (p = .58), and freedom from endograft instability was 98 ± 2% vs. 97 ± 3% (p = .46), respectively. CONCLUSION: Both off the shelf devices provided excellent early and one year results. The E-nside may require shorter thoracic aortic coverage and bridging length for the renal arteries, and less frequent implantation of a concomitant proximal thoracic or distal abdominal bifurcated endograft. However, these aspects did not determine significant differences in clinical outcomes.

OBJECTIVE: This multicentre study aimed to assess the early and midterm outcomes of physician modified fenestrated endografts (PMEGs) for endovascular aortic arch repair in zone 0. METHODS: Between 2018 and 2022, a retrospective study was conducted in three centres of consecutive patients undergoing endovascular aortic arch repair in zone 0 with PMEGs. Endpoints included technical success, 30 day mortality rate, major adverse events, secondary interventions, stent stability, target vessel patency, and overall survival. RESULTS: A total of 54 patients (mean age 63 years; 45 males) with aortic arch pathology were included, comprising aortic dissections (n = 32; 59%) and aortic arch aneurysms (n = 22; 41%). Technical success was 98%. One patient died from stroke within 30 days. Major adverse events included stroke (n = 4; 7%), retrograde type A dissection (RTAD) (n = 3; 6%), and acute kidney injury (n = 2; 4%). During a median follow up of 12 months, there were two deaths (4%) of unknown cause at one month and 1.5 months, and no aortic related death. Type Ia, type Ic, and type IIIc endoleaks were observed in two (4%), three (6%), and two (4%) patients, respectively. No vessel stenosis was observed. Re-intervention was required in 10 patients (19%). Estimates of overall survival, freedom from secondary intervention, and freedom from target vessel instability at one year were 94.2% (standard error [SE] 3.3%), 81.8% (SE 6.0%), and 92.0% (SE 4.5%), respectively. CONCLUSION: This study has demonstrated the efficacy of PMEGs for zone 0 endovascular aortic arch repair, with acceptable technical success and mortality rates. Stroke, RTAD, and re-intervention rates remain a concern for endovascular therapy. A larger population and long term outcomes are required to assess the safety and durability of this technique as a beneficial choice for endovascular aortic arch repair in specialised centres.

The use of thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysm (TAA) and Stanford type B aortic dissection (TBAD) has been increasing; however, in terms of etiology, the differences of long term after TEVAR outcomes remain unexplored. Thus, we investigated etiology-specific long-term results of TEVAR for TAA and TBAD. A total of 421 TEVAR procedures were performed at our institution from July 2007 to December 2021; 249 TAA cases and 172 TBAD cases were included. Traumatic aortic dissection and aortic injury cases were excluded. The mean observation duration was 5.7 years. The overall 30-day mortality rate was 1.4% (n = 6), with 1.2% (n = 3) in the TAA group and 1.7% (n = 3) in the TBAD group. The overall incidence of postoperative stroke was 0.9% (n = 4), with 1.2% (n = 3) and 0.6% (n = 1) in the TAA and TBAD groups, respectively (p = 0.90). Paraplegia developed in 1.7% (n = 7) of patients, with 2.4% (n = 6) in the TAA group and 0.6% (n = 1) in the TBAD group. Freedom from aortic-related death was not significantly different between the two etiologies; however, thoracic reintervention was more common in the TBAD group (p = 0.003), with endoleak being the most common indication for reintervention. Additionally, retrograde type A aortic dissection occurred in four TBAD cases, while migration occurred in three TAA cases. The perioperative results of TEVAR for TAA and TBAD were satisfactory. The long-term results were unfavorable owing to the occurrence of etiology-specific and common complications. In terms of the high frequency of reintervention, the long-term complications associated with TEVAR are etiology specific.

BACKGROUND: The benefits and harms associated with femoral artery cannulation over other sites of arterial cannulation for surgical repair of acute Stanford type A aortic dissection (TAAD) are not conclusively established. METHODS: We evaluated the outcomes after surgery for TAAD using femoral artery cannulation, supra-aortic arterial cannulation (i.e., innominate/subclavian/axillary artery cannulation), and direct aortic cannulation. RESULTS: 3751 (96.1%) patients were eligible for this analysis. In-hospital mortality using supra-aortic arterial cannulation was comparable to femoral artery cannulation (17.8% vs. 18.4%; adjusted OR 0.846, 95% CI 0.799-1.202). This finding was confirmed in 1028 propensity score-matched pairs of patients with supra-aortic arterial cannulation or femoral artery cannulation (17.5% vs. 17.0%, p = 0.770). In-hospital mortality after direct aortic cannulation was lower compared to femoral artery cannulation (14.0% vs. 18.4%, adjusted OR 0.703, 95% CI 0.529-0.934). Among 583 propensity score-matched pairs of patients, direct aortic cannulation was associated with lower rates of in-hospital mortality (13.4% vs. 19.6%, p = 0.004) compared to femoral artery cannulation. Switching of the primary site of arterial cannulation was associated with increased rate of in-hospital mortality (36.5% vs. 17.0%; adjusted OR 2.730, 95% CI 1.564-4.765). Ten-year mortality was similar in the study cohorts. CONCLUSIONS: In this study, the outcomes of surgery for TAAD using femoral arterial cannulation were comparable to those using supra-aortic arterial cannulation. However, femoral arterial cannulation was associated with higher in-hospital mortality than direct aortic cannulation. TRIAL REGISTRATION: ClinicalTrials.gov registration code: NCT04831073.
