Abstract
Acute type A aortic dissection may originate from a primary intimal tear located in the ascending aorta and often extends retrogradely into the aortic root. How to prevent bleeding in the aortic root and eliminate false lumen is very important in aortic dissection. We have developed a modified anastomotic technique that involves inverting adventitial and graft into aorta and reinforcing with a felt strip on the external border of the aortic wall. Since 2020, 45 consecutive patients with type A aortic coarctation have undergone this aortic root reconstruction procedure, to date, none have been reopened for bleeding or remnant dissection.

Abstract
OBJECTIVE The study objective was to evaluate the clinical and radiographic outcomes of the Ascyrus Medical Dissection Stent in a prospective, nonrandomized, international study (Dissected Aorta Repair Through Stent Implantation) of patients with acute DeBakey type I aortic dissection. METHODS The Ascyrus Medical Dissection Stent was used in combination with the standard surgical management of acute DeBakey type I aortic dissection I to treat patients with (56.5%, 26/46) and without (43.5%, 20/46) preoperative clinical and radiographic malperfusion. All patients had a primary entry tear in the ascending aorta, and 97.8% (45/46) were treated with a hemiarch repair. Median follow-up was 3 years. RESULTS All 47 patients underwent emergency surgical repair with successful Ascyrus Medical Dissection Stent implantation. One patient was excluded from analysis due to use in iatrogenic dissection. Overall mortality at 30 days and 3 years was 13.0% (6/46) and 21.7% (10/46), respectively. Overall new stroke rate at 30 days was 15.2% (7/46). No devices were explanted at any time during the 3-year median follow-up. At 3 years, the total aortic diameter in zones 0, 1, and 2 decreased or remained stable in 91.7%, 72.7%, and 75.0%, respectively. The false lumen was completely or partially thrombosed in 90.5% in zone 0, 60.0% in zone 1, and 68.2% in zone 2 at 3 years. CONCLUSIONS The use of the Ascyrus Medical Dissection Stent in the treatment of acute DeBakey type I aortic dissection I holds promise as a simple technology that enables repair of the aortic arch and proximal descending aorta, while promoting positive aortic remodeling. Ongoing follow-up of the Dissected Aorta Repair Through Stent Implantation trial will provide long-term, prospective, clinical outcomes and radiographic data on positive remodeling of the aortic arch.

Abstract
Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) may be useful in treating exsanguinating trauma patients. This study seeks to compare rates of success, complications and time required for vascular access between ultrasound-guidance and surgical cut-down for femoral sheath insertion as a prospective observational case control study. Participating clinicians from either trauma surgery or anesthesiology were allocated to surgical cut-down or percutaneous ultrasound-guided puncture on a 1:1 ratio. Time spans to vessel identification, successful puncture, and balloon inflation were recorded. 80 study participants were recruited and allocated to 40 open cut-down approaches and 40 percutaneous ultrasound-guided approaches. REBOA catheter placement was successful in 18/40 cases (45%) using a percutaneous ultrasound guided technique and 33/40 times (83%) using the open cut-down approach (p < 0.001). Median times [in seconds] compared between percutaneous ultrasound-guided puncture and surgical cut-down were 36 (18-73) versus 117(56-213) for vessel visualization (p < 0.001), 136 (97-175) versus 183 (156-219) for vessel puncture (p < 0.001), and 375 (240-600) versus 288 (244-379) for balloon inflation (p = 0.08) overall. Access to femoral vessels for REBOA catheter placement is safer when performed by cut-down and direct visualization but can be performed faster by an ultrasound-guided technique when vessels can be identified clearly and rapidly.

Abstract
OBJECTIVES Aortic pathologies often present with elevated inflammatory biomarkers due to the nature of the disease. Open aortic surgery causes significant trauma to the body due to often mandatory ischemic periods, long cardiopulmonary bypass times and polytransfusion. We aim to determine postoperative trends on inflammation biomarkers for different aortic pathologies and type of surgery in different segments of the aorta. METHODS Retrospective review of prospectively collected data of 193 consecutive patients who underwent aortic surgery in our centre between 2017 and 2021, grouped according to the type of aortic intervention: (1) Type A aortic dissection (AD) repair with ascending aorta/hemiarch replacement, (2) Aortic root replacement (ARR), (3) Aortic arch + Frozen elephant trunk (FET), (4) Descending thoracic aorta (DTA)/Thoraco-Abdominal aortic repair (TAA). Primary outcomes were daily values of white blood cells (WBC) and C-Reactive Protein (CRP) during the first 15 postoperative days. RESULTS All groups had a similar inflammatory peak in the first 2-4 days (WBC 12-15 × 109 c/L). AD and FET groups show similar trends with WBC and CRP peaks on days 2 and 10. The ARR group didn't experience the 2nd peak as most patients were already discharged. DTA/TAA patients experienced a more prolonged inflammatory response, reaching a plateau by day 5-10. AD group shows the highest WBC levels and the DTA/TAAA group the highest CRP levels. CRP levels remain elevated (100-200 mg/L) in all groups after 15 postoperative days. CONCLUSIONS Inflammatory biomarkers show different postoperative trends depending on the clinical presentation and complexity of the aortic procedure performed. Further understanding of the inflammatory response to different aortic pathologies and surgical procedures will permit reduction on the liberal use of antibiotics that this cohort of patients are usually exposed to. An earlier version of the data included in this manuscript was presented as Oral Abstract in the UK Society of Cardiothoracic Surgery Annual meeting in 2021.

Abstract
BACKGROUND Fungal endocarditis is a rare but serious condition associated with high mortality rates. Various predisposing factors contribute to its occurrence, such as underlying cardiac abnormalities, cardiac surgeries, prosthetic cardiac devices, and central venous catheters. Diagnosing fungal endocarditis, particularly Aspergillus, poses challenges, often complicated by negative blood cultures. CASE PRESENTATION This report details a case of extensive ascending aorta involvement in Aspergillus endocarditis (AE) in a 24-year-old man with a history of bioprosthesis aortic valve replacement (AVR). Three months post-AVR, he presented with pericardial effusion and aortic rupture, leading to a redo biological valved conduit aortic root replacement (Bentall surgery). Despite the intervention, the tubular graft exhibited extensive Aspergillus involvement, resulting in graft disruption and significant peri-aortic infection. A second redo procedure involving aortic homograft root replacement was performed. Unfortunately, the patient succumbed two days after the surgery. CONCLUSION A combined approach of medical and surgical therapies is recommended to manage fungal endocarditis. Despite efforts, the mortality rate associated with Aspergillus endocarditis remains unacceptably high, with no significant difference observed between combination therapy and antifungal treatment alone. Further research is essential to explore novel therapeutic strategies and improve outcomes for patients with this challenging condition.

Abstract
INTRODUCTION Transseptal punctures (TSPs) are widely used in left atrium and left ventricle surgery. Accidental puncture of the puncture needle into the aorta is a rare complication that is rarely reported but has serious consequences. The appropriate management of this complication remains unclear. PATIENT CONCERNS This report describes a case of a male with the chief complaint: paroxysmal palpitation for 1 year, aggravated for 1 month. DIAGNOSIS The electrophysiological diagnosis was atrioventricular reentrant tachycardia caused by left-side bypass. INTERVENTIONS Radiofrequency ablation of the heart was a necessary treatment and a TSP operation was needed, in which a puncture was mistakenly believed to have entered the aorta, a series of measures were taken urgently. Although the surgical procedure in this case was a false alarm, we still initiated a series of emergency plans. Emergency measures to address the complications were effectively implemented, and the emergency measures were promptly terminated after it was clear that complications had been misjudged. OUTCOMES At last, it was confirmed that the angiogram was a pulmonary artery image, not an aorta image. Then the atrial septal puncture operation was successfully completed, and under the guidance of the Carto system, the ablation was successfully completed. Postoperative fluoroscopy showed no complications, such as pericardial effusion. After 2 years of follow-up, there was no reoccurrence of tachycardia, and there were no complications. It is crucial that emergency procedures are terminated in a timely manner after a clear miscarriage of performance. Although accidental puncture into the aorta is urgent and serious, performing a blockage or even thoracotomy in an emergency if complications are not clearly confirmed can cause further damage to the patient and would be a definitively wrong strategy. CONCLUSION Strict and standardized TSP operations can avoid complications. Correct judgment of the authenticity of complications is crucial, and remedial measures that may cause further damage should not be blindly adopted. The retention of the aortic guide wire can provide convenient access for further differential diagnosis and remedial treatment.

Abstract
INTRODUCTION Resuscitative endovascular balloon occlusion of the aorta (REBOA) has the potential to cause clinically relevant systemic ischemic burden with long durations of aortic occlusion (AO). We aimed to examine the association between balloon occlusion time and clinical complications and mortality outcomes in patients undergoing zone 1 REBOA. METHODS A retrospective cohort analysis of American Association for the Surgery of Trauma Aortic Occlusion for Resuscitation in Trauma and Acuteregistry patients with Zone 1 REBOA between 2013 and 2022 was performed. Patients with cardiopulmonary resuscitation on arrival or who did not survive past the emergency department were excluded. Total AO times were categorized as follows: <15 min, 15-30 min, 31-60 min, and >60 min. Clinical and procedural variables and in-hospital outcomes were compared across groups using bivariate and multivariate regression analyses. RESULTS There were 327 cases meeting inclusion criteria (n = 51 < 15 min, 83 15-30 min, 98 31-60 min, and 95 > 60 min, respectively). AO >60 min had higher admission lactate (8 ± 6; P = 0.004) compared to all other time groups, but injury severity score, heart rate, and systolic blood pressure were similar. Group average times from admission to definitive hemorrhage control ranged from 82 to 103 min and were similar across groups (85 min in AO >60 group). Longer AO times were associated with greater red blood cell, fresh frozen plasma transfusions (P < 0.001), and vasopressor use (P = 0.001). Mortality was greatest in the >60 min group (73%) versus the <15 min, 15-30 min, and 31-60 min groups (53%, 43%, and 45%, P < 0.001). With adjustment for injury severity score, systolic blood pressure, and lactate, AO >60 min had greater mortality (OR 3.7, 95% CI 1.6-9.4; P < 0.001) than other AO duration groups. Among 153 survivors, AO >60 min had a higher rate of multiple organ failure (15.4%) compared to the other AO durations (0%, 0%, and 4%, P = 0.02). There were no differences in amputation rates (0.7%) or spinal cord ischemia (1.4%). acute kidney injury was seen in 41% of >60 min versus 21%, 27%, and 33%, P = 0.42. CONCLUSIONS Though greater preocclusion physiologic injury may have been present, REBOA-induced ischemic insult was correlated with poor patient outcomes, specifically, REBOA inflation time >60 min had higher rates of mortality and multiple organ failure. Minimizing AO duration should be prioritized, and AO should not delay achieving definitive hemostasis. Partial REBOA may be a solution to extend safe AO time and deserves further study.

Abstract
OBJECTIVES The American Association for Thoracic Surgery 2010 guidelines stipulate that rapid growth of the aorta (>3 mm/y) is an indication for prophylactic surgical intervention. Because of the many potential sources of error in aortic measurement (including measurement variability and comparison of noncorresponding segments), we explored whether rapid aortic growth was a reality or a falsehood. METHODS Among 2781 patients with aortic disease who were treated over 3 decades, we examined aortic growth rate in 811 patients with at least 2 aortic images taken at least 2 years apart. We identified 42 ascending and 27 descending patients with putative rapid aortic growth. A team of experienced clinicians reread the source images. RESULTS Among the 42 ascending patients with putative rapid aortic growth, rapid growth was confirmed in 12 and refuted in 11 (19 images nonretrievable). Among the 27 descending patients, rapid growth was confirmed in 6 and refuted in 4 (17 images nonretrievable). We calculated lower, middle, and highest possible rapid growth rates by prorating positivity rates for nonretrievable scans. Lowest, middle, and highest possible rates of rapid growth were 2.7%, 4.7%, and 6.9% for ascending aorta, and 1.6%, 4.3%, and 7.3% for descending aneurysms, respectively. Middle rates are considered most accurately reflective. Of the patients with confirmed rapid growth, 3 of 4 inoperable patients succumbed to their aorta. Twenty-three patients underwent prompt surgery, with 22 survivors. For the rapidly growing aortas, operative, pathologic, and genetic findings are reported. CONCLUSIONS Although not a falsehood, rapid growth is uncommon for the ascending and descending aorta. Many putative cases are reflective of measurement error. Attention to potential sources of measurement error is key. VIDEO ABSTRACT.

Abstract
Surgical intervention is often used in the management of heart failure in patients with adult congenital heart disease. This review addresses anatomic variations and complications due to prior surgical interventions, including sternal reentry, collateral vessels, and the neo-aortic root after the Damus-Kaye-Stansel procedure. Surgical considerations for systemic atrioventricular valvular surgery, Fontan revision, and advanced heart failure therapies including ventricular assist devices, heart transplant, and combined heart-liver transplant are discussed, with a focus on unique patient populations including those with systemic right ventricles and those with Fontan circulation.

Abstract
ABSTRACT Migration and embolization of a deployed stent is a rare complication of percutaneous coronary interventions (PCI) and can result in serious and potentially life-threatening complications. There are many reports of intracoronary stent entrapment, stripping, and dislodgement during PCI, however, only a few reports about migration. We report a rare case of migration of the left main coronary stent into the aortic root, which happened 5 months after the procedure and was treated by its partial removal through aortotomy along with surgical revascularization. The patient was discharged 5 days later, after an uneventful hospital stay.

Abstract
A 66-year-old man presented with hemolytic anemia, which required frequent blood transfusion, 6 months after surgical repair of an ascending aortic pseudoaneurysm. Hemolysis was attributed to luminal stenosis caused by graft kinking by laboratory test, CT and four-dimensional magnetic resonance imaging. First, an Excluder cuff was placed at the stenotic site under rapid pacing, but it migrated distally. Thereafter a Palmaz XL stent was placed at the stenotic site, which led to resolution of anemia. In this case, a Palmaz XL stent was successfully used to treat hemolytic anemia caused by graft kinking following ascending aortic surgery.

Abstract
OBJECTIVES This study investigated early and late outcomes between ascending aorta/partial arch replacement and total arch replacement with entry resection in DeBakey type I acute aortic dissection (DIAAD) repair. METHODS AND RESULTS This study included 98 patients who underwent DIAAD repair from January 2005 to December 2020. Seventy-four patients underwent ascending aorta and partial arch replacement with entry resection (Non-TAR group), and 24 underwent total arch replacement with entry resection (TAR group). The mean follow-up period was 4.8 ± 3.2 years. The follow-up rate was 92.3%. The mean age in the Non-TAR and TAR groups was 68.8 ± 10.4 years and 61.6 ± 13.7 years, respectively (P = 0.046). No difference in preoperative shock and malperfusion syndrome was observed between the groups. Hospital death was observed in 5.4% and 12.5% of the Non-TAR and TAR groups, respectively (P = 0.241). Postoperative permanent neurologic deficits and temporary hemodialysis were more frequently seen in the TAR compared to the Non-TAR group (P = 0.03 and 0.003, respectively). The 5-year survival rates were 95.1% ± 3.4% and 89.2% ± 7.2% in the Non-TAR and TAR groups, respectively (Log-rank P = 0.603). Freedom from downstream aorta-related reinterventions at 5 years was 87.8% ± 4.5% and 64.1% ± 11.0% in the Non-TAR and TAR groups, respectively (Log-rank P = 0.007). Three patients in each group underwent thoracic endovascular aortic repair for residual aortic dissection. CONCLUSIONS Early and late outcomes in the Non-TAR group were satisfactory compared to those in the TAR group. Entry resection with graft replacement remains a standard approach in DIAAD repair.

Abstract
BACKGROUND Reduction of variability through process reengineering can improve surgical results for patients with type A acute aortic syndrome. We compare short-term results before and after implementation of an Aorta Code for patients with type A acute aortic syndrome who underwent surgery. METHODS The Aorta Code was implemented in a 5-hospital healthcare network in 2019. This critical pathway was based on a simple diagnostic algorithm, ongoing training, immediate patient transfer, and treatment by an expert multidisciplinary team. We retrospectively compared all patients operated on in our center before (2005-2018) and after (January 2019 to February 2023) its implementation. RESULTS One hundred two and 70 patients underwent surgery in the precode and code periods, respectively. In the code period the number of patients operated on per year increased (from 7.3 to 16.8), and the median elapsed time until diagnosis (6.5 hours vs 4.2 hours), transfer (4 hours vs 2.2 hours), and operating room (2.7 hours vs 1.8 hours) were significantly shorter (P < .05). Aortic root repair and total arch replacement were more frequent (66.7% vs 82.9% [P = .003] and 20.6% vs 40% [P = .001]). Cardiopulmonary bypass and ischemia times were also shorter (179.7 minutes vs 148.2 minutes [P = .001] and 105 minutes vs 91.2 minutes [P = .022]). Incidence of prolonged mechanical ventilation (53.9% vs 34.3%, P = .011), major stroke (17.7% vs 7.1%, P = .047), and 30-day mortality (27.5% vs 7.1%, P = .001) decreased significantly. CONCLUSIONS An Aorta Code can be successfully implemented by using a standardized protocol within a hospital network. The number of cases increased; time to diagnosis, transfer, and operating room were reduced; and 30- day mortality significantly decreased.

Abstract
OBJECTIVE Reoperative sternotomy is associated with poor outcomes after cardiac surgery. We aimed to investigate the impact of reoperative sternotomy on the outcomes after aortic root replacement. METHODS All patients who underwent aortic root replacement from January 2011 to June 2020 were identified using the Society of Thoracic Surgeons Adult Cardiac Surgery Database. We compared outcomes between patients who underwent first-time aortic root replacement with those with a history of sternotomy undergoing reoperative sternotomy aortic root replacement using propensity score matching. Subgroup analysis was performed among the reoperative sternotomy aortic root replacement group. RESULTS A total of 56,447 patients underwent aortic root replacement. Among them, 14,935 (26.5%) underwent reoperative sternotomy aortic root replacement. The annual incidence of reoperative sternotomy aortic root replacement increased from 542 in 2011 to 2300 in 2019. Aneurysm and dissection were more frequently observed in the first-time aortic root replacement group, whereas infective endocarditis was more common in the reoperative sternotomy aortic root replacement group. Propensity score matching yielded 9568 pairs in each group. Cardiopulmonary bypass time was longer in the reoperative sternotomy aortic root replacement group (215 vs 179 minutes, standardized mean difference = 0.43). Operative mortality was higher in the reoperative sternotomy aortic root replacement group (10.8% vs 6.2%, standardized mean difference = 0.17). In the subgroup analysis, logistic regression demonstrated that individual patient repetition of (second or more resternotomy) surgery and annual institutional volume of aortic root replacement were independently associated with operative mortality. CONCLUSIONS The incidence of reoperative sternotomy aortic root replacement might have increased over time. Reoperative sternotomy is a significant risk factor for morbidity and mortality in aortic root replacement. Referral to high-volume aortic centers should be considered in patients undergoing reoperative sternotomy aortic root replacement.

Abstract
Transcatheter aortic valve implantation (TAVI) and thoracic endovascular aortic repair (TEVAR) are minimally invasive procedures for treating aortic valves and diseases. Finite element simulations have proven to be valuable tools in predicting device-related complications. In the literature, the inclusion of aortic pre-stress has not been widely investigated. It plays a crucial role in determining the biomechanical response of the vessel and the device-tissue interaction. This study aims at demonstrating how and when to include the aortic pre-stress in patient-specific TAVI and TEVAR simulations. A percutaneous aortic valve and a stent-graft were implanted in aortic models reconstructed from patient-specific CT scans. Two scenarios for each patient were compared, i.e., including and neglecting the wall pre-stress. The neglection of pre-stress underestimates the contact pressure of 48% and 55%, the aorta stresses of 162% and 157%, the aorta strains of 77% and 21% for TAVI and TEVAR models, respectively. The stent stresses are higher than 48% with the pre-stressed aorta in TAVI simulations; while, similar results are obtained in TEVAR cases. The distance between the device and the aorta is similar with and without pre-stress. The inclusion of the aortic wall pre-stress has the capability to give a better representation of the biomechanical behavior of the arterial tissues and the implanted device. It is suggested to include this effect in patient-specific simulations replicating the procedures.

Abstract
OBJECTIVE The purpose of this study is to assess the mid-term outcomes of aortic root replacement after repair of CHDs. METHOD This is a single-institutional retrospective, cohort study with consecutive patients undergoing aortic root replacement after surgical repair of CHDs between 1999 and 2022. Operative indications included aortic root dilatation with/without aortic insufficiency, sinus of Valsalva rupture, or aortic dissection involving the root. RESULTS Forty-four patients (36 male and 8 female) were enrolled. Mean age at the root replacement was 36.6 ± 11.9 years. The most frequent primary diagnosis was congenital aortic stenosis (n = 10) and ventricular septal defect (n = 10). Mean time from the surgical repair to aortic root replacement was 26.6 ± 13.0 years. Operative indications were aortic root enlargement with or without aortic valve aetiology (n = 40), sinus of Valsalva rupture (n = 2), and aortic dissection (n = 2). Forty-two patients underwent valve-replacing aortic root replacement, and two patients underwent valve-sparing, with 40 concomitant procedures. The median follow-up was 3.5 (1.3-7.6) years. There were one early and five late mortalities and five cardiovascular-related reoperations. Actuarial survival at 5-10 years after root replacement was 81.0 ± 6.6%. The cumulative incidence of cardiovascular-related reoperation and aortic root or valve-related reoperation at 5 years after root replacement was 11.9% and 5.6%, respectively. CONCLUSION The early and mid-term outcomes of aortic root replacement for patients with a history of repair of CHDs were favourable in terms of survival and aortic root or valve-related reoperation.

Abstract
OBJECTIVE Studies of reintervention after valve-sparing aortic root replacement (VSRR) are limited by sample size and failure to evaluate all types of reinterventions, including distal aorta and transcatheter interventions. In this report, reintervention after VSRR using a large patient cohort was comprehensively analyzed. METHODS In a series involving 2 academic aortic centers, 781 consecutive patients from 2005 to 2020 undergoing David V VSRR for aortic aneurysm (91%) or dissection (9%) were included. Median age was 50 years, and 23% had a bicuspid aortic valve (AV). Median follow-up was 7.0 years. Open or transcatheter reintervention on the AV, proximal, or distal thoracic aorta was identified. Cumulative incidence was calculated, and subdistribution hazard models identified factors associated with reintervention. Time-dependent incidence of reintervention was plotted using risk-hazard functions. RESULTS Sixty-eight reinterventions (57 open, 11 transcatheter) were performed. Reinterventions were divided by indication into degenerative AV (n = 26, including 1 transcatheter aortic valve replacement), endocarditis (n = 11), proximal aorta (n = 8), and distal aorta (n = 23, including 10 thoracic endovascular aortic repairs). Risk of reintervention for endocarditis peaked 1 to 3 years after VSRR, whereas other indications had stable, low rates of occurrence throughout the follow-up period. The cumulative incidence of reintervention was 12.5% whereas the cumulative incidence of AV reintervention was 7.0% at 10 years and was associated with residual postoperative aortic insufficiency. In-hospital mortality after reintervention was 3%. CONCLUSIONS Reintervention rates after VSRR are relatively low in long-term follow-up and can be performed with acceptable operative risk. The majority of reinterventions are performed for indications other than AV degeneration, with the timing of reintervention varying by the specific clinical indication.

Abstract
BACKGROUND Primary infected abdominal aortic aneurysms (PIAAAs) are associated with high morbidity and mortality. Three repair approaches include open in-situ repair (OIR), extra-anatomic repair (EAR), and endovascular abdominal aortic aneurysm repair (EVAR). This study is one of the largest single-center case series comparing the outcomes of the different surgical approaches for PIAAA. METHODS This is a retrospective cohort study of all patients treated surgically for PIAAA between 2000 and 2021. PIAAA diagnosis was defined as the presence of an abdominal aortic aneurysm with evidence of infection on clinical presentation, laboratory markers, radiology, or surgically. Patients with prior aortic surgery were excluded from this study. Basic demographics were compared across the 3 surgical groups using standard statistical methods. Our primary outcomes included mortality at 1 and 5 years. Kaplan-Meier curves were generated and compared using log-rank testing. Multivariate Cox proportional hazards models were created to assess determinants of mortality. RESULTS A total of 43 patients were included in the full cohort. Patients undergoing EVAR more often had diabetes, end-stage renal disease, and coronary artery disease. EVAR was also more often done in patients with a saccular aneurysm rather than fusiform. (93% vs. 70% in EAR and 42% in OIR; P = 0.015). All-cause mortality rates at 1 year were not significantly different between the 3 groups. Survival at 5 years did show a significant benefit of OIR over EVAR and EAR: OIR had an 8% mortality rate with EAR having a 53% rate and EVAR having the highest (72%) mortality rate at 5 years (P = 0.03). Multivariable Cox regression analysis showed that EVAR (aHR 12.1, (95% CI 1.42 to 103.9), P = 0.02) and EAR (aHR 15.1, (95% CI 1.59 to 143.3), P = 0.0.02) had an increased 5-year mortality risk when compared to OIR. CONCLUSIONS Repair of primary infected aortic aneurysm is associated with high complication and mortality rates regardless of the approach. In our studied sample, OIR offered an improved long-term survival without added benefits in terms of complication rates. In infected AAA, EVAR should be considered bridging stage between the urgent situation and eventual open repair.

Abstract
OBJECTIVE This single-center retrospective study evaluated early and midterm outcomes of 100 consecutive patients with type A intramural hematoma. METHODS Initial watch-and-wait strategy was indicated if the maximum aortic diameter was < 50 mm, pain score was < 3/10 on the numerical rating scale, and no ulcer-like projection was observed in the ascending aorta. The primary endpoints of this study were all-cause and aorta-related deaths, and the secondary endpoint was aortic events. RESULTS Initial watch-and-wait strategy was indicated in 52 patients. Emergency aortic repair was indicated in the remaining 48 patients; 2, 31, and 15 patients died before surgery, underwent emergency surgery, and declined emergency surgery, respectively. Among the watch-and-wait group, 11 (21%) patients underwent aortic repair during hospitalization. In-hospital mortality rates, 5-year survival rates, and 5-year freedom from aorta-related death were not significantly different between the initial watch-and-wait strategy and emergency surgery (2% vs. 6%, 92% vs. 82%, and 100% vs. 94%, respectively). In the initial watch-and-wait strategy group, 5-year freedom from aortic events and freedom from aortic events involving the ascending aorta were 60% and 66%, respectively. CONCLUSIONS The early and midterm outcomes with the initial watch-and-wait strategy in patients with type A intramural hematoma with a maximum aortic diameter of ≤ 50 mm, pain score of ≤ 3/10, and no ulcer-like projection in the ascending aorta were favorable with no aorta-related death.

Abstract
INTRODUCTION We report a single-center experience of resection and reconstruction of the heart and aorta infiltrated by lung cancer in order to prove that involvement of these structures is no longer a condition precluding surgery. METHODS Twenty-seven patients underwent surgery for lung cancer presenting full-thickness infiltration of the heart (n = 6) or the aorta (n = 18) and/or the supra-aortic branches (subclavian n = 3). Cardiac reconstruction was performed in 6 patients (5 atrium, 1 ventricle), with (n = 4) or without (n = 2) cardiopulmonary bypass, using a patch prosthesis (n = 4) or with deep clamping and direct suture (n = 2). Aortic or supra-aortic trunk reconstruction (n = 21) was performed using a heart-beating crossclamping technique in 14 cases (8 patch, 4 conduit, 2 direct suture), or without crossclamping by placing an endovascular prosthesis before resection in 7 (4 patch, 3 omental flap reconstruction). Neoadjuvant chemotherapy was administered in 13 patients, adjuvant therapy in 24. RESULTS All resections were complete (R0). Nodal staging of lung cancer was N0 in 14 cases, N1 in 10, N2 in 3. No intraoperative mortality occurred. Major complication rate was 14.8%. Thirty-day and 90-day mortality rate was 3.7%. Median follow-up duration was 22 months. Recurrence rate is 35.4% (9/26: 3 loco-regional, 6 distant). Overall 3- and 5-year survival is 60.9% and 40.6%, respectively. CONCLUSIONS Cardiac and aortic resection and reconstruction for full-thickness infiltration by lung cancer can be performed safely with or without cardiopulmonary bypass and may allow long-term survival of adequately selected patients.

Abstract
OBJECTIVES Tracheal reconstruction post-extensive resection remains an unresolved challenge in thoracic surgery. This study evaluates the use of aortic allografts (AAs) for tracheal replacement and reconstruction in a rat model, aiming to elucidate the underlying mechanisms of tracheal regeneration. METHODS AAs from female rats were employed for tracheal reconstruction in 36 male rats, with the replacement exceeding half of the tracheal length. To avert collapse, silicone stents were inserted into the AA lumens. No immunosuppressive therapy was administered. The rats were euthanized biweekly, and the AAs were examined for neovascularization, cartilage formation, respiratory epithelial ingrowth, submucosal gland regeneration and the presence of the Sex-determining region of Y-chromosome (SRY) gene. RESULTS All procedures were successfully completed without severe complications. The AA segments were effectively integrated into the tracheal framework, with seamless distinction at suture lines. Histological analysis indicated an initial inflammatory response, followed by the development of squamous and mucociliary epithelia, new cartilage ring formation and gland regeneration. In situ hybridization identified the presence of the SRY gene in newly formed cartilage rings, confirming that regeneration was driven by recipient cells. CONCLUSIONS This study demonstrates the feasibility of AAs transforming into functional tracheal conduits, replicating the main structural and functional characteristics of the native trachea. The findings indicate that this approach offers a novel pathway for tissue regeneration and holds potential for treating extensive tracheal injuries.

Abstract
OBJECTIVES After staged reconstruction for hypoplastic left heart syndrome, the neoaortic root tends to dilate, and the incidence of significant neoaortic valve insufficiency increases with time. This study aimed to evaluate the mid-term outcomes of the neoaortic root geometries and valve function after chimney reconstruction in the Norwood procedure. METHODS Between 2013 and 2021, 20 consecutive patients who underwent chimney reconstruction during the Norwood procedure for hypoplastic left heart syndrome and its variants in our institution were enrolled. The actual diameters of the following points were measured, and Z-scores were calculated based on the normal aortic root geometries using the long axis view of echocardiography at the pre-Norwood stage and the lateral view of angiography at pre-Glenn, pre-Fontan, post-Fontan and follow-up (age 5-6 years) stages: neoaortic valve annulus; sinus of Valsalva; sinotubular junction; and ascending aorta just proximal to the anastomosis to the aortic arch. The degree of neoaortic valve regurgitation was evaluated by echocardiography at each stage. RESULTS The median follow-up period was 3.9 years. Neoaortic roots after chimney reconstruction were spared from progressive dilation over time. With growth, the conical configuration of the neoaortic roots was preserved without geometrical distortion. The Z-scores of the annulus, sinus of Valsalva, sinotubular junction and ascending aorta ranged roughly from 4 to 6, 4 to 6, 2 to 4 and 0 to 2, respectively. All neoaortic valves at each stage had mild or no regurgitation. CONCLUSIONS Chimney reconstruction prevented neoaortic root dilation and avoided significant neoaortic valve regurgitation in the mid-term. These neoaortic dimensions with smooth flow profiles in the neoaorta after chimney reconstruction may have contributed to the current results. Further studies are needed to clarify the long-term outcomes.

Abstract
BACKGROUND Three-dimensional aortic root evaluation using virtual reality (VR) techniques for valve-sparing aortic root replacement (VSARR) preparation has not yet been implemented, so we demonstrated VR computed tomography (VR-CT) and assessed its utility for VSARR.Methods and Results: We enrolled 72 patients who underwent multidetector CT before elective VSARR for annuloaortic ectasia with tricuspid aortic valve. The geometries of their aortic roots were measured with a VR-CT workstation. The mean values of geometric height (GH), free margin length (FML), and commissural height (CH) were 17.2±2.4 mm, 36.0±5.2 mm, and 24.0±4.3 mm, respectively. The right coronary/noncoronary CH was significantly greater than the left coronary/right coronary and left coronary/noncoronary CH. The left coronary cusp had the shortest FML, intercommissural distances (ICD), and smallest central angle. Although the right coronary cusp had the largest values for FML, ICD, and central angle, the right coronary cusp had the lowest GH and EH. The VR-CT measurements strongly correlated with intraoperative alternatives, especially with mean GH (R2=0.75) and left coronary/noncoronary CH (R2=0.79). Furthermore, mean GH was observed to be significantly different among the selected graft size groups; therefore, the preoperative mean GH could play a significant role in graft sizing. CONCLUSIONS VR-CT evaluation allows a thorough understanding of aortic root anatomy, which could facilitate VSAAR.

Abstract
BACKGROUND Iatrogenic aortic dissection (IAD) is a rare but highly lethal complication that may occur following coronary artery bypass grafting (CABG) surgery. Aortic dissection (AD) is often asymptomatic, making early detection difficult. We aimed to optimize preoperative evaluation strategies of CABG surgery for minimizing the incidence of IAD and assess early recognition and management of IAD for improving outcomes. METHODS Electronic databases were searched to identify all case reports of patients undergoing CABG surgery who developed IAD. Clinical characteristics, operative information, perioperative management, and patient outcomes were compiled and analyzed. RESULTS Nineteen case reports involving 27 patients aged 50 to 81 were included. Patients were from Europe (n = 23) and Asia (n = 4), mostly men (n = 25). The aorta was described as normal, abnormal, and unmentioned (n = 8, 5, and 14, respectively). Sixteen patients had a bypass with more than 3 grafts. Most patients (n = 25) experienced type A dissection. There were intraoperative (n = 12) and postoperative (n = 15) cases. Surgery (n = 19) was the most common treatment, with 9 patients selecting deep hypothermic circulatory arrest. Eighteen patients were restored to health, while 9 patients died (3 died before treatment). CONCLUSIONS Our study focused on patients with IAD and developed a recommended management protocol for patients undergoing CABG surgery.

Abstract
BACKGROUND We investigated long-term outcomes, particularly later aorta operations and overall death in patients who underwent aortic valve replacement for bicuspid aortic valve without aortic surgery. METHODS Between January 2002 and December 2022, 274 patients underwent aortic valve replacement for bicuspid aortic valve at our institution. Of them, 181 patients who did not undergo aortic surgery, in accordance with current guidelines, were analyzed retrospectively. RESULTS The median follow-up duration was 6.1 (2.0-10.6) years, and follow-up was completed in 97.8% of pateints. There were 3 patients (1.7%) who underwent later aorta operation during follow-up period. The cumulative later aorta operation rate at 10 years adjusting overall death as competing risk was 16.3%, and the estimated rates of freedom from overall death at 10 years was 83.7%. Fine-Gray competing risk regression model showed that aortic valve stenosis was only the predictor of later aorta operation (hazard ratio 8.477; p = 0.012). In multivariable Cox models, predictors of overall death were aortic valve stenosis (hazard ratio: 8.270, 95% confidence interval: 1.082-63.235; p = 0.042) and operation time (hazard ratio: 1.011, 95% confidence interval: 1.004-1.017; p = 0.002). CONCLUSIONS Patients with bicuspid aortic valve with ascending aortic diameter less than 45 mm are at low risk of later aorta operation after isolated aortic valve replacement.

Abstract
BACKGROUND Despite advancements in diagnostic methods and emergency interventions, mortality rates of ruptured abdominal aortic aneurysm (rAAA) continue to remain high. To address this issue, the resuscitative endovascular balloon occlusion of the aorta (REBOA) technique has been designed to provide temporary control of bleeding. We aimed to compare the impact of the REBOA technique during open aortic surgery for rAAA. METHODS Between January 2014 and November 2021, 53 consecutive patients (46 males, 7 females; mean age 71.9 ± 7.9 years; range 51-89 years) who underwent emergency open aortic surgery for rAAA were retrospectively analyzed. Patients were divided into REBOA (21 patients) and non-REBOA (32 patients) groups. The primary outcomes were postoperative 24-hr and 30-day mortality. The secondary outcomes were intensive care unit (ICU) stay, in-hospital stay, bleeding, postoperative renal failure, bowel ischemia, and transient ischemic attack (TIA)/stroke rate. RESULTS The REBOA group showed a significant reduction in mortality rates at both 24 hr (9.5% vs. 37.5%, P = 0.029) and 30 days (14.2% vs. 43.7%, P = 0.035) compared to the non-REBOA group. In-hospital stay (12.8 ± 3.48 vs. 15.6 ± 4.74 days, P = 0.02) and ICU stay (2.42 ± 2.08 vs. 5.09 ± 5.79 days, P = 0.048) were shorter among the REBOA group. Total procedure time and bleeding were reduced among the REBOA group without significant differences in terms of postoperative renal failure, bowel ischemia, and TIA/stroke rate. CONCLUSIONS The REBOA group demonstrated significantly improved survival rates compared to the non-REBOA group, without a significant difference in complication rates. REBOA is considered a less invasive option compared to the traditional method for open aortic cross-clamping. This study demonstrated that the use of REBOA may be considered as a first-line treatment option for open surgery in cases of rAAA particularly when an off-the-shelf endovascular aneurysm repair device is not suitable.

Abstract
OBJECTIVES Since 2000, we anastomosed the saphenous vein graft to the right coronary artery system using the stump of the right internal thoracic artery as inflow. The long-term results of patients where the right coronary artery was grafted with the right internal thoracic artery or the ascending aorta as saphenous vein inflow has not been reported. METHODS From 2000 to 2018, 699 consecutive patients had right internal thoracic artery elongated with saphenous vein (I-graft group, n = 358, 51.2%) or saphenous vein from the aorta (Ao-graft group, n = 341, 48.8%) on right coronary artery system. Inclusion criteria were age ≤75 years, bilateral internal thoracic arteries as a Y graft on the left system (three-vessel disease, n = 603, 86.3%) or as a left internal thoracic artery on left anterior descending and right internal thoracic artery elongated with saphenous vein on the right coronary artery system (two-vessel disease, n = 96, 13.7%), only 1 saphenous vein per patient. Propensity-matching identified 272 patients per group. One-hundred and twenty-two patients underwent coronary computed tomographic angiography to asses grafts patency after a median follow-up of 88 (65-93) months. RESULTS In the paired samples, there was no difference in the early outcome. Ten-year survival and freedom from death, non-fatal acute myocardial infarction and repeat revascularization were higher in I-graft group: 90.6 [standard error (SE): 2.0] vs 78.2 (SE: 5.3), P = 0.0266, and 85.2 (SE: 2.4) vs 69.9 (SE: 5.3), P = 0.0179. Saphenous vein graft, at a long-time follow-up, showed a higher patency rate (81.6% (SE: 7.0) vs 50.7% (SE: 7.9), P < 0.0001) and a smaller internal lumen diameter (2.7, standard deviation: 0.4 vs 3.4, standard deviation: 0.6 mm, P < 0.0001) when right internal thoracic artery was the inflow. CONCLUSIONS Grafting the right coronary artery with saphenous vein may entail higher patency rate and better outcome when the inflow is the right internal thoracic artery than when is the ascending aorta. Prospective randomized data are needed to test this hypothesis.

Abstract
OBJECTIVE We compared perioperative outcomes of patients with acute type A aortic dissection undergoing hemiarch (HA) versus extended arch (EA) repair with or without descending aortic intervention. METHODS Nine hundred twenty-nine patients underwent acute type A aortic dissection repair (2002-2021, 9 centers) including open distal repair (HA) with or without additional EA repair. EA with intervention on the descending aorta (EAD) included elephant trunk, antegrade thoracic endovascular aortic replacement, or uncovered dissection stent. EA with no descending intervention (EAND), included unstented suture-only methods. Primary outcomes were in-hospital mortality, permanent neurologic deficit, computed tomography malperfusion resolution, and a composite. Multivariable logistic regression was also performed. RESULTS Mean age was 66 ± 18 years, 30% (278 out of 929) were women, and HA was performed more frequently (75% [n = 695]) than EA (25% [n = 234]). EAD techniques included: dissection stent (39 out of 234 [17%]), thoracic endovascular aortic replacement (18 out of 234 [7.7%]), and elephant trunk (87 out of 234 [37%]). In-hospital mortality (EA: n = 49 [21%] and HA: n = 129 [19%]; P = .42), and neurological deficit (EA: n = 43 [18%] and HA: n = 121 [17%]; P = .74) were similar. EA was not independently associated with death (EA vs HA odds ratio, 1.09; 95% CI, 0.77-1.54; P = .63) or neurologic deficit (EA vs HA odds ratio, 0.85; 95% CI, 0.47-1.55; P = .59). Composite adverse events differed significantly (EA vs HA odds ratio, 1.47; 95% CI, 1.16-1.87; P = .001). Malperfusion resolved more frequently after EAD (EAD: n = 32 [80%], EAND: n = 18 [56%], HA: n = 71 [50%]; P = .004), although multivariable analysis was not significant (EAD vs HA odds ratio, 2.17; 95% CI, 0.83-5.66; P = .10). CONCLUSIONS Extended arch interventions pose similar perioperative mortality and neurologic risks as Hemiarch. Descending aortic reinforcement may promote malperfusion restoration. Extended techniques should be approached with caution in acute dissection due to increased risk of adverse events.

Abstract
BACKGROUND The purpose of this study is to find the high-risk morphological features in type B aortic dissection (TBAD) population and to establish an early detection model. METHODS From June 2018 to February 2022, 234 patients came to our hospital because of chest pain. After examination and definite diagnosis, we excluded people with previous cardiovascular surgery history, connective tissue disease, aortic arch variation, valve malformation, and traumatic dissection. Finally, we included 49 patients in the TBAD group and 57 in the control group. The imaging data were retrospectively analyzed by Endosize (Therevna 3.1.40) software. The aortic morphological parameters mainly include diameter, length, direct distance, and tortuosity index. Multivariable logistic regression models were performed and systolic blood pressure (SBP), aortic diameter at the left common carotid artery (D3), and length of ascending aorta (L1) were chosen to build a model. The predictive capacity of the models was evaluated through the receiver operating characteristic (ROC) curve analysis. RESULTS The diameters in the ascending aorta and aortic arch are larger in the TBAD group (33.9 ± 5.9 vs. 37.8 ± 4.9 mm, p < 0.001; 28.2 ± 3.9 vs. 31.7 ± 3.0 mm, p < 0.001). The ascending aorta was significantly longer in the TBAD group (80.3 ± 11.7 vs. 92.3 ± 10.6 mm, p < 0.001). Besides, the direct distance and tortuosity index of the ascending aorta in the TBAD group increased significantly (69.8 ± 9.0 vs. 78.7 ± 8.8 mm, p < 0.001; 1.15 ± 0.05 vs. 1.17 ± 0.06, p < 0.05). Multivariable models demonstrated that SBP, aortic diameter at the left common carotid artery (D3), and length of ascending aorta (L1) were independent predictors of TBAD occurrence. Based on the ROC analysis, area under the ROC curve of the risk prediction models was 0.831. CONCLUSION Morphological characteristic including diameter of total aorta, length of ascending aorta, direct distance of ascending aorta, and tortuosity index of ascending aorta are valuable geometric risk factors. Our model shows a good performance in predicting the incidence of TBAD.

Abstract
Formation of a pseudoaneurysm due to blood leakage from the anastomotic site of the vascular graft in large-diameter vessels is often seen, but formation of a pseudoaneurysm from the non-anastomotic site is extremely rare. A 68-year-old woman presented with a history of double valve replacement for combined valvular disease at 37 years old and hemiarch replacement for thoracic aortic dilatation at 65 years old. She visited the emergency room with a 2-week history of chest pain. Contrast-enhanced computed tomography (CT) revealed a 5-cm-diameter pseudoaneurysm and extravasation from the ascending aorta, so emergency surgery was performed. Around the ascending aorta area, we confirmed bleeding from a 5-mm dehiscence in the non-anastomotic part of the graft prosthesis, so hemostasis was performed with a cross-stitch mattress suture over a felt strip. Initially, the cause of the pseudoaneurysm was unknown, but re-examination of CT images from after the previous hemiarch replacement confirmed contact between the sternal wire and graft prosthesis. The wire was thus considered to have caused damage and bleeding. The patient was discharged from the hospital with a good postoperative course and is being followed-up in the outpatient department.

Abstract
OBJECTIVES The decision to undergo aortic aneurysm repair balances the risk of operation with the risk of aortic complications. The surgical risk is typically represented by perioperative mortality, while the aneurysmal risk relates to the 1-year risk of aortic events. We investigate the difference in 30-day and 1-year mortality after total arch replacement for aortic aneurysm. METHODS This was an international two-centre study of 456 patients who underwent total aortic arch replacement for aneurysm between 2006 and 2020. Our primary end-point of interest was 1-year mortality. Our secondary analysis determined which variables were associated with 1-year mortality. RESULTS The median age of patients was 65.4 years (interquartile range 55.1-71.1) and 118 (25.9%) were female. Concomitantly, 91 (20.0%) patients had either an aortic root replacement or aortic valve procedure. There was a drop in 1-year (81%, 95% confidence interval (CI) 78-85%) survival probability compared to 30-day (92%, 95% CI 90-95%) survival probability. Risk hazards regression showed the greatest risk of mortality in the first 4 months after discharge. Stroke [hazard ratio (HR) 2.54, 95% CI (1.16-5.58)], renal failure [HR 3.59 (1.78-7.25)], respiratory failure [HR 3.65 (1.79-7.42)] and reoperation for bleeding [HR 2.97 (1.36-6.46)] were associated with 1-year mortality in patients who survived 30 days. CONCLUSIONS There is an increase in mortality up to 1 year after aortic arch replacement. This increase is prominent in the first 4 months and is associated with postoperative complications, implying the influence of surgical insult. Mortality beyond the short term may be considered in assessing surgical risk in patients who are undergoing total arch replacement.

Abstract
OBJECTIVES To evaluate the results after selective sinus replacement (SSR) for aortic root remodeling in bicuspid aortopathy. METHODS Among 662 patients who underwent root repair using SSR between 2005 and 2020, there were 114 with bicuspid aortopathy. SSR was performed either as an isolated procedure (31) or as an adjunct to aortic valve repair (83) and was adjusted to the existing aortic annulus diameter rather than a downsized diameter. In valves with asymmetrical commissural orientation, the repair aimed for the achievement of a 180°-commissural orientation. RESULTS Abolishment of aortic insufficiency (AI) ≥2+ using root repair alone was only possible in 2 patients with acute-dissection-related AI, yet isolated root repair was also performed in 29 further patients with no/mild AI. All remaining patients with AI ≥2+ presented cusp-related regurgitation and necessitated an additional valve repair. During the mean follow-up of 91 months (range, 13-196), a relevant valve defect (AI ≥3+ in 8, stenosis in 2) occurred in 10 patients (all after combined repair) resulting in an estimated freedom from a relevant aortic valve defect and/or reoperation of 96 ± 2%, 89 ± 4%, and 82 ± 6% at 5, 10, and 12 years, respectively. Echocardiographically, no patient revealed a considerable change of form or size of the repaired root nor was any root reintervention necessary. CONCLUSIONS Patient-tailored root repair using SSR is a very effective and durable valve-sparing approach for bicuspid aortopathy. Aortic cusp repair is decisive for both abolishment of AI in bicuspid aortopathy and for the functional durability of the repaired aortic valve.
