Abstract
OBJECTIVE To evaluate the early and mid-term outcomes of open repair in patients with thoracoabdominal aortic aneurysm (TAAA) after thoracic endovascular aortic repair (TEVAR). METHODS This was a retrospective single center study. Data were retrospectively collected and analyzed for consecutive patients undergoing open TAAA repair (TAAAR) after TEVAR from November 2016 to June 2021. Indications for TAAAR included aneurysm progression due to endoleak, persisted false lumen perfusion, proximal/distal disease progression, and aorta rupture. The risk factor of operative mortality was analyzed by multivariable logistic regression model and the survival was evaluated by Kaplan-Meier. RESULTS Sixty-three patients who met the inclusion criteria for the study were identified. The mean age at TAAAR was 41 ± 12 years and 43 (68.3%) were male. Marfan syndrome (MFS) was presented in 39 patients (61.9%). 60 (95.2%) patients presented with post-dissection aneurysm and 3 (4.8%) patients with degenerative aneurysm. The extent of TAAA was Crawford I in 9 (14.3%), II in 22 (34.9%), III in 23 (36.5%), and IV in 9 (14.3%). Emergent TAAAR was done in 10 (15.9%) patients, and deep hypothermic circulatory arrest was used in 22 (34.6%). Endograft was explanted in 31 (49.2%). Operative mortality was 11 (17.5%). Stroke, paraplegia, and acute kidney failure occurred in 5 (7.9%), 7 (11.1%), and 6 (9.5%) patients, respectively. Pulmonary complications occurred in 19 (30.2%) patients. The estimated survival was 74.8 ± 4.9% at 5 years. Late reoperations were performed in 2 patients at 2.5 years and 1.3 years, respectively. CONCLUSIONS In this series of TAAA after TEVAR, TAAAR was related with a high risk of operative mortality and morbidity and the midterm outcomes represented a durable treatment and were respectable.

Abstract
BACKGROUND The prevalence and etiology of acute aortic dissection type A in patients ≤30 years is unknown. The aims of this clinical study were to determine the prevalence and potential etiology of acute aortic dissection type A in surgically treated patients ≤30 years and to evaluate the respective postoperative outcomes in this selective group of patients in a large multi-centre study. METHODS Retrospective data collection was performed at the 16 participating international aortic institutions. All patients ≤30years at the time of dissection onset were included. The postoperative results were analysed with regard to connective tissue disease. RESULTS The overall prevalence of acute aortic dissection type A ≤ 30years was 1.8% (139 out of 7914 patients), including 51(36.7%) patients who were retrospectively diagnosed with connective tissue disease. Cumulative postoperative mortality was 8.6%, 2.2% and 1.4%, respectively. Actuarial survival was 80% at 10 years postoperatively. Non- connective tissue disease patients (n = 88) had a significantly higher incidence of arterial hypertension (46.6%vs.9.8%;p<0.001) while acute aortic dissection type A affected the aortic root (p < 0.001) and arch (p = 0.029) significantly more often in the connective tissue disease group. A positive family history of aortic disease was present in 9.4% of the study cohort(n = 13). CONCLUSIONS The prevalence of acute aortic dissection type A in surgically treated patients ≤30 years is less than 2% with connective tissue disease and arterial hypertension as the two most prevalent triggers of acute aortic dissection type A. Open surgery may be performed with good early results and excellent mid- to long-term outcomes.

Abstract
BackgroundAortic regurgitation (AR) related to Behcet's disease (BD) is rare, but usually fatal. Perivalvular leakage (PVL) is high if AR related to BD treated with regular AVR. In this study, we report the surgical management of AR secondary to BD.MethodsBetween September 2017 and April 2022, 38 patients with AR secondary to Behcet's disease had surgery in our center. 17 patients did not have a BD diagnosis before surgery, 2 of them were diagnosed during surgery and received Bentall procedure. The remaining 15 patients received conventional AVR. 21 patients were diagnosed as BD before surgery, all of them received modified Bentall procedures. All patients were followed up by regular outpatient visits, transthoracic echocardiogram and CT angiography were performed to evaluate the aorta and aortic valve.ResultsSeventeen patients did not have a BD diagnosis at the time of surgery. Out of them, 15 patients received conventional AVR, and a total of 13 patients suffered PVL after surgery. Twenty-one patients had a BD diagnosis before surgery. They received modified Bentall procedures and IST and steroids were given both pre- and post-surgery. In this group treated with Bentall procedure no patient suffered PVL during follow up.ConclusionsPVL is a complex scenario after conventional AVR for AR in BD. Modified Bentall procedure seems superior to isolated AVR in these cases. The use of IST and steroids before and after surgery in combination with modified Bentall procedure could have a role in effectively reducing PVL.

Abstract
Background This study investigated the impact of coronary angiography on outcomes of emergency operation in acute type A aortic dissection (ATAAD) patients who were initially misdiagnosed as an acute coronary syndrome. Methods From October 2016 to April 2019, 129 patients underwent emergency operation for ATAAD in our institution, including 21 patients (16.3%, coronary angiography group) who received preoperative coronary angiography without knowledge of the ATAAD, and the rest 108 did not (Non-coronary angiography group). Preoperative clinical characteristics, 30-day mortality and postoperative complications were compared. Multivariable logistic regression was performed to confirm the independent prognostic factors for short-term and long-term outcomes. Results Patients undergoing coronary angiography had higher prevalence of preoperative hypotension or shock (61.9% vs 35.2%, P = 0.022), ischemic changes on electrocardiogram (66.7% vs 37.0%, P = 0.012), platelet inhibition (ADP-induced inhibition 92.0% vs 46.0%, P = 0.001), and coronary involvement (66.7% vs 30.6%, P = 0.002). 30-day mortality was 4.8% versus 9.3% (P = 0.84). Coronary angiography group had more intraoperative bleeding (1900 ml vs 1500 ml, P = 0.013) and chest-tube drainage on the first postoperative day (1040 ml vs 595 ml, P = 0.028). However, preoperative coronary angiography was not independent risk factors for 30-day mortality (OR 0.171, 95%CI 0.013–2.174, P = 0.173) and overall survival (HR 0.407; 95%CI 0.080–2.057; P = 0.277). Conclusion Patients undergoing coronary angiography carried a higher risk of preoperative hemodynamic instability, myocardial ischemia, and perioperative bleeding. However, unintentional coronary angiography did not have a significant impact on short-term and long-term outcomes of emergency surgery in ATAAD.

Abstract
OBJECTIVES Data are scarce and mixed regarding the impact of preoperative dual antiplatelet therapy (DAPT) on the surgical outcomes of acute type A aortic dissection (ATAAD). We seek to evaluate the impact of DAPT on bleeding-related events and early- and mid-term mortality after total arch replacement and frozen elephant trunk in such patients. METHODS This study comprised 48 ATAAD patients on preoperative DAPT and 418 without DAPT (the whole series, i.e. unmatched cohort), from which 45 matched pairs were selected by propensity score (matched cohort). Bleeding-related events (reoperation for bleeding, bleeding of ≥1500 ml within the first 12 h postoperatively or transfusion of ≥10 units of red blood cell or use of recombinant activated factor VII), operative mortality and mid-term survival were compared in the unmatched and matched cohorts. The impact of preoperative DAPT was evaluated with multivariable analysis. RESULTS In the unmatched cohort, bleeding of ≥1500 ml/12 h postoperatively was more common in the DAPT group (18.8% vs 8.4%, P = 0.020); operative mortality was 9.7%, which did not differ with DAPT (12.5% vs 9.3%, P = 0.48). Nor did bleeding-related events (54.2% vs 43.5%, P = 0.16) differ significantly between 2 groups. In the matched cohort, neither were drainage of ≥1500 ml/12 h (20% vs 6.7%, P = 0.063) and bleeding-related events (53.3% vs 42.2%, P = 0.30), nor operative mortality (13.8 vs 8.9%, P = 0.50) and mid-term survival (79.3% vs 76.4%, P = 0.93) significantly different between 2 groups. DAPT was not identified as a predictor for operative mortality [odd ratio (OR) 0.97, 95% confidence interval (CI) 0.31-3.08; P = 0.96; adjusted OR 1.28, 95% CI 0.22-7.20; P = 0.78] and bleeding-related events (OR 1.50, 95% CI 0.76-2.95; P = 0.24; adjusted OR 2.03, 95% CI 0.80-3.66; P = 0.14). CONCLUSIONS In patients with ATAAD undergoing total arch replacement and frozen elephant trunk, although preoperative DAPT led to more postoperative bleeding, it did not increase bleeding-related events nor operative mortality nor mid-term death. The results of this study imply that for patients with ATAAD, emergency surgical repair, even if as extensive as total arch repair, should not be contraindicated or delayed simply because of ongoing DAPT.

Abstract
Background Although obstructive sleep apnoea (OSA) is prevalent among patients with aortic dissection, its prognostic impact is not yet determined in patients undergoing major vascular surgery. We aimed to investigate the association of OSA with hypoxaemia and with prolonged intensive care unit (ICU) stay after type A aortic dissection (TAAD) repair. Methods This retrospective study continuously enrolled 83 patients who underwent TAAD repair from January 1 to December 31, 2018. OSA was diagnosed by sleep test and defined as an apnoea hypopnea index (AHI) of ≥ 15/h, while an AHI of > 30/h was defined severe OSA. Hypoxaemia was defined as an oxygenation index (OI) of < 200 mmHg. Prolonged ICU stay referred to an ICU stay of > 72 h. Receiver operating characteristic curve analysis was performed to evaluate the predictive value of postoperative OI for prolonged ICU stay. Multivariate logistic regression was performed to assess the association of OSA with hypoxaemia and prolonged ICU stay. Results A total of 41 (49.4%) patients were diagnosed with OSA using the sleep test. Hypoxaemia occurred postoperatively in 56 patients (67.5%). Postoperatively hypoxaemia developed mostly in patients with OSA (52.4% vs. 83.0%, p = 0.003), and particularly in those with severe OSA (52.4% vs. 90.5%, p = 0.003). The postoperative OI could fairly predict a prolonged ICU stay (area under the receiver-operating characteristic curve, 0.72; 95% confidence intervals [CI] 0.60–0.84; p = 0.002). Severe OSA was associated with both postoperative hypoxaemia (odds ratio [OR] 6.65; 95% CI 1.56–46.26, p = 0.008) and prolonged ICU stay (OR 5.58; 95% CI 1.54–20.24, p = 0.009). Conclusions OSA was common in patients with TAAD. Severe OSA was associated with postoperative hypoxaemia and prolonged ICU stay following TAAD repair.

Abstract
AIM To evaluate the effect of packed red blood cells (pRBCs), fresh frozen plasma (FFP), and platelet concentrate (PC) transfusions on acute kidney injury (AKI) in patients with acute Stanford type A aortic dissection (ATAAD) with total arch replacement (TAR). METHOD From December 2015 to October 2017, 421 consecutive patients with ATAAD undergoing TAR were included in the study. The clinical data of the patients and the amount of pRBCs, FFP, and PC were collected. Acute kidney injury was defined using the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Logistic regression was used to identify whether pRBCs, FFP, and platelet transfusions were risk factors for KDIGO AKI, stage 3 AKI, and AKI requiring renal replacement therapy (RRT). RESULTS The mean ± standard deviation age of the patients was 47.67±10.82 years; 77.7% were men; and the median time from aortic dissection onset to operation was 1 day (range, 0-2 days). The median transfusion amount was 8 units (range, 4-14 units) for pRBCs, 400 mL (range, 0-800 mL) for FFP, and no units (range, 0-2 units) for PC. Forty-one (41; 9.7%) patients did not receive any blood products. The rates of pRBC, PC, and FFP transfusions were 86.9%, 49.2%, and 72.9%, respectively. The incidence of AKI was 54.2%. Considering AKI as the endpoint, multivariate logistic regression showed that pRBCs (odds ratio [OR], 1.11; p<0.001) and PC transfusions (OR, 1.28; p=0.007) were independent risk factors. Considering KDIGO stage 3 AKI as the endpoint, multivariate logistic regression showed that pRBC transfusion (OR, 1.15; p<0.001), PC transfusion (OR, 1.28; p<0.001), a duration of cardiopulmonary bypass (CPB) ≥293 minutes (OR, 2.95; p=0.04), and a creatinine clearance rate of ≤85 mL/minute (OR, 2.12; p=0.01) were independent risk factors. Considering RRT as the endpoint, multivariate logistic regression showed that pRBC transfusion (OR, 1.12; p<0.001), PC transfusion (OR, 1.33; p=0.001), a duration of CPB ≥293 minutes (OR, 3.79; p=0.02), and a creatinine clearance rate of ≤85 mL/minute (OR, 3.34; p<0.001) were independent risk factors. CONCLUSIONS Kidney Disease: Improving Global Outcomes-defined stage AKI was common after TAR for ATAAD. Transfusions of pRBCs and PC increased the incidence of AKI, stage 3 AKI, and RRT. Fresh frozen plasma transfusion was not a risk factor for AKI.

Abstract
Two-dimensional (2D) materials with complete spin-polarization, high-speed conduction electrons, large Curie temperatures and robust ferromagnetic ground states are desirable for spintronic applications. Based on first-principles calculations, we demonstrate that the 1T-CrO2 monolayer is an intrinsic 3d ferromagnetic Dirac half metal (DHM) with two symmetry protected Dirac cones near the Fermi level. The Fermi velocities (3.21 × 105 m s-1 and 4.85 × 105 m s-1) of the Dirac cones are in the same order as that of graphene, indicating its excellent transport properties. Its 2.48 eV half-metallic gap is large enough to prevent the spin-flip transition. Moreover, the two Dirac cones are robust against biaxial strain of up to ±4%. The robust ferromagnetism is mainly contributed by the 3d states of Cr and its Curie temperature is up to 507 K. Our results indicate that the ferromagnetic 1T-CrO2 monolayer is a promising candidate for high temperature, high efficiency spintronics applications.

Abstract
This study aimed to investigate whether extracellular vesicles (EVs) secreted in myocardial infarction (MI) plasma could protect against apoptosis of bone marrow mesenchymal stem cells (BMSCs) following hypoxia or serum deprivation in vitro and improve cardiac function following MI in vivo. The plasma samples were taken from female rats 24 h after MI. EVs were obtained and co-cultured with BMSCs. We found that EVs could be taken up by BMSCs. Co-culturing with EVs attenuated hypoxia-induced apoptosis of BMSCs in EVs in a dose-dependent manner, which was reversed by the pharmacological inhibition of AKT signaling. Co-culturing with EVs improved transplantation efficiency and blunted MI-induced apoptosis of BMSCs in vivo. Furthermore, transplantation of BMSCs together with EVs can effectively promote the increase in capillary density both at the border and central zone of myocardium and ameliorate myocardial remodeling in MI rats. BMSCs and EVs transplantation treatment exhibited significant improvements in ejection fraction, fraction shortening, left ventricular end-diastolic dimensions, and left ventricular end-systolic dimensions, as evaluated by echocardiography four weeks after MI in rats. Finally, levels of differentiation- and apoptosis-related microRNAs expression in EVs that may mediate these effects were also identified by microarray and quantitative real-time PCR. In conclusion, the present results suggest a potential role of plasma-derived EVs in decreasing apoptosis of BMSCs by activating AKT signaling, promoting angiogenesis, ameliorating myocardial remodeling, and improving cardiac function in MI rats. EV application may be a novel option to ameliorate the therapeutic efficiency of BMSCs to improve cardiac function following MI.

Abstract
The morbidity and mortality of myocardial ischemia-reperfusion injury (MIRI) have increased in modern society. Noncoding RNAs (ncRNAs), including lncRNAs, circRNAs, piRNAs and miRNAs, have been reported in a variety of studies to be involved in pathological initiation and developments of MIRI. Hence this review focuses on the current research regarding these ncRNAs in MIRI. We comprehensively introduce the important features of lncRNAs, circRNAs, piRNA and miRNAs and then summarize the published studies of ncRNAs in MIRI. A clarification of lncRNA-miRNA-mRNA, lncRNA-transcription factor-mRNA and circRNA-miRNA-mRNA axes in MIRI follows, to further elucidate the crucial roles of ncRNAs in MIRI. Bioinformatics analysis has revealed the biological correlation of mRNAs with MIRI. We provide a comprehensive perspective for the roles of these ncRNAs and their related networks in MIRI, providing a theoretical basis for preclinical and clinical studies on ncRNA-based gene therapy for MIRI treatment.

Abstract
BACKGROUND In this study, we investigated the impact of concomitant coronary artery bypass grafting (CABG) on operative and midterm mortality in patients with acute type A aortic dissection (ATAAD) undergoing surgical repair. METHODS From January 2012 to December 2014, among 489 patients (mean age: 47.6 ± 10.4 years, 77.1% male) with ATAAD who received surgical repair at our institute, 21 patients (4.3%) underwent concomitant CABG. Isolated aortic repair was performed in the remaining 468 cases (95.7%). Coronary dissection was indicated in 15 patients (Neri classification type B in 2, type C in 13), concomitant coronary artery disease in five and coronary artery compression in one. The follow-up time was 97.3% at 44.1 ± 13.9 months. RESULTS A total of 44 patients (9%) died from surgery, and operative mortality in the concomitant CABG group was significantly higher than that in the isolated aortic repair group (47.6%, 10/21 vs. 7.3%, 34/468; P < 0.001). Among the 11 survivors in the concomitant CABG group, no deaths occurred during the follow-up. Cox regression indicated that concomitant CABG increased the operative mortality risk by 9.2 times (HR, 9.26; 95% CI, 4.31-19.89; P < 0.001). Although it predicted a 5.2-fold increase in overall mortality (HR, 5.20; 95% CI, 2.55-10.61; P < 0.001), concomitant CABG did not affect midterm death (P = 0.996). CONCLUSIONS Concomitant CABG carries a significant operative risk in ATAAD patients undergoing surgical repair. However, survivors may benefit from concomitant CABG and had similar midterm mortality compared with the other cases.

Abstract
Background This study aimed to evaluate whether the use of mild hypothermic circulatory arrest (HCA) with selective cerebral perfusion (SCP) in open arch procedure provides comparable perioperative results to moderate HCA for patients with dissected or degenerative arch pathologies. Methods Between January 2017 and September 2020, a total of 88 consecutive patients (mean age 47±11 years, 71 males) underwent open arch repair under a single surgeon at our institution with mild or moderate systemic hypothermia assisted by unilateral or bilateral SCP. Patients were divided into groups according to the nasopharyngeal temperature at the beginning of HCA: a moderate HCA group (n=47, 53.4%) and a mild HCA group (n=41, 46.6%). The postoperative mortality, morbidity, and visceral organ functions between these groups were analyzed retrospectively. Results Compared to the moderate HCA group, the mild HCA group had a significantly higher core temperature (nasopharynx: 24.4±0.8 vs. 28.5±2, P<0.001; bladder 25.9±0.9 vs. 30±1.2, P<0.001), and the incidence of major adverse events (MAE) in this group was markedly lower (21.3% vs. 4.9%, P=0.031). No differences were identified between the two groups refer to in-hospital mortality, permanent neurological deficit (PND), temporary neurological deficit (TND), and paraplegia (8.5% vs. 2.4%, P=0.366; 8.5% vs. 0, P=0.120; 6.4% vs. 7.3%, P=1.0; 4.3% vs. 2.4%, P=1.0, respectively). In the moderate HCA group, 6 patients (12.8%) developed acute renal failure needing replacement therapy, which did not occur in the mild HCA group (P=0.028). The duration of ventilator support and intensive care unit stay was shorter in the mild HCA group, as well as a decreased volume of drainage during the first 24 h and reduced platelet transfusion. Conclusions The preliminary results of the mild HCA group with SCP applied in open arch repair, mainly in total arch replacement (TAR) and stented elephant trunk (SET) implantation for aortic dissection, were satisfactory. Furthermore, comparable inferior outcomes were obtained with mild HCA compared with that of the conventional moderate HCA strategy. These encouraging surgical and postoperative results favor this more aggressive hypothermia strategy in open arch repair.

Abstract
BACKGROUND The aim of this study is to test if the newly proposed 45 mm size criterion for ascending aortic replacement (AAR) in bicuspid aortic valve (BAV) patients undergoing aortic valve replacement (AVR) is predictive of improved early outcomes. METHODS Data of 306 BAV patients with an aortic diameter of ≥45 mm undergoing AVR alone or with AAR were retrospectively analyzed. Patients were divided into groups of AVR + AAR (n = 220) and AVR only (n = 86) based on if surgery was performed according to the 45 mm criterion. End point was early adverse events, including 30-day and in-hospital mortality, cardiac events, acute renal failure, stroke, and reoperation for bleeding. Cox regression was used to assess if conformance to 45 mm criterion could predict fewer early adverse events. RESULTS AVR + AAR group had significantly higher postoperative left ventricular ejection fraction (LVEF) (0.59 ± 0.09 vs. 0.55 ± 0.11, p = 0.006) and longer cardiopulmonary bypass (CPB) time (128 vs. 111 minutes, p = 0.002). Early adverse events occurred in 45 patients (14.7%), which was more prevalent in the AVR-only group (22.1% vs. 11.8%, p = 0.020). Conformance to the 45 mm criterion predicted lower rate of early adverse events (hazard ratio [HR]: 0.53, 95% confidence interval [CI]: 0.28-0.98, p = 0.042). After adjustment for gender, age, AAo diameter, sinuses of Valsalva diameter, preoperative LVEF, Sievers subtypes, BAV valvulopathy, and CPB and cross-clamp times, conformance to the 45 mm size criterion still predicted lower incidence of early adverse events (HR: 0.37, 95% CI: 0.15-0.90, p = 0.028). CONCLUSIONS This study shows that conformance to 45 mm size cutoff for preemptive AAR during aortic valve replacement in patients with BAV was not associated with increased risk for adverse events and may improve early surgical outcomes.

Abstract
Background This study analyzes the outcomes of a one-stage hybrid procedure combining thoracic endovascular aortic repair (TEVAR) with extra-anatomic bypass in patients with distal aortic arch disease. Methods This retrospective study collected 103 hybrid procedures combining TEVAR with extra-anatomic bypass (mean age, 62.2±9.3 years; 90 males) performed from January 2009 to January 2019 at Beijing Anzhen Hospital. We analyzed 30-day and mid-term outcomes including survival rate and the incidence of stroke, spinal cord injury (SCI), and endoleak. Results Five deaths (4.6%) occurred within 30 days, including type I endoleak in Zone 1 (n=1), hemorrhagic shock (n=1), stroke (n=2), and stent migration (n=1). Two patients developed SCI. The median follow-up time was 39.5 (interquartile range, 13.6-69.0) months. In all, 14 late deaths occurred; these were due to stroke (n=2), severe pneumonia (n=1), aortic rupture caused by type I endoleak (n=3), and sudden death (n=8). Six late endoleaks occurred including three type I and one type II in Zone 1 and two type I in Zone 2. In a competing risks analysis, the incidences of reintervention at 7 years, late death, and survival without reintervention were 8%, 22%, and 70%, respectively. In a Cox risk model, stroke (HR, 21.602; 95% CI: 2.798–166.796; P=0.003) was the only risk factor for 30-day mortality. Stroke (HR, 19.484; 95% CI: 5.245–72.380; P<0.001), SCI (HR, 15.548; 95% CI: 2.754–87.786; P=0.002), and endoleak (HR, 4.626; 95% CI: 1.068–20.040; P=0.041) were independent risk factors for long-term mortality. Conclusions The one-stage hybrid procedure provides acceptable mid-term results with good mid-term patency of extra-anatomic bypass. Strict selection of patients suitable for hybrid repair can effectively improve the survival rate and reduce the incidence of complications. At the same time, close follow-up patients should receive close long-term follow-up after hybrid procedure.

Abstract
OBJECTIVE This study aimed to investigate the relationship between the duration of cardiopulmonary bypass (CPB) and stroke or early death in patients with acute type A aortic dissection (ATAAD) receiving total aortic arch replacement with the frozen elephant trunk procedure (TAR with FET). METHODS A retrospective cohort study of 258 consecutive patients was conducted at Beijing Anzhen Hospital from December 2014 to June 2016. Patients who received TAR with FET for ATAAD were included. An adverse outcome (AO) was defined as 30-day mortality or stroke. Additionally, an AO was compared using propensity score matching. RESULTS The incidence of AO was 13.6% (n = 35). The 30-day mortality rate was 10.8% and the stroke rate was 9.3%. Patients were aged 47.9 ± 10.6 years old. The duration of CPB was an independent predictor of occurrence of AO after adjusting for confounding factors by multivariable logistic regression analysis (odds ratio 1.101, 95% confidence interval 1.003-1.208). In matched analysis, CPB duration remained a risk factor of AO. CONCLUSIONS The duration of CPB is an independent predictor of AO in surgical repair for ATAAD. The underlying mechanisms of this association are important for developing improved prevention strategies.

Abstract
OBJECTIVES We seek to report our management protocol and early outcomes of acute type A aortic dissection (ATAAD) repair during the early phase of coronavirus disease 2019 (COVID-19). METHODS From January 23 to April 30, 2020, we performed ATAAD repair for 33 patients, including three with pregnancy-related TAADs. Confirmation of COVID-19 depended on the results of two nucleic acid tests and pulmonary computed tomography scan. Based on testing results and hemodynamic stability, patients were triaged to an isolated intensive care unit or negative pressure operating room for emergency surgery. RESULTS Mean age 50.2 ± 13.3 years and 20 were male (60.1%) and 8 patients were febrile (>37.3°C; 24.2%) and 17 were lymphopenic (51.5%). No patient was excluded from COVID-19 infection preoperatively. Extensive aortic repair with total arch replacement (TAR) was performed in 24 (72.7%), and limited proximal repair in 9 patients (27.3%). Cardiopulmonary bypass and cross-clamp times averaged 177 ± 34 and 88 ± 20 min for TAR, and 150 ± 30 and 83 ± 18 min for hemiarch, respectively. The mean operation time was 410 ± 68.3 min. Operative mortality was 6.1% (2/33). Complications included reintubation in four (12.1%), acute kidney failure in two (6.1%), and cerebral infarction in one (3.0%). No paraplegia nor re-exploration for bleeding occurred. COVID-19 was excluded in 100% eventually. No nosocomial infection occurred. Nor did any patient/surgical staff develop fever or test positive during the study period. CONCLUSIONS The results of this study show that our management protocol based on testing results and hemodynamic stability in patients with ATAAD during the COVID-19 pandemic was effective and achieved favorable early surgical outcomes.

Abstract
BACKGROUND The optimal hypothermic level in total arch replacement with stented elephant trunk implantation for acute type A aortic dissection (aTAAD) has not been established, and the superiority of unilateral or bilateral cerebral perfusion remains a controversial issue. Therefore, we evaluated the application of moderate hypothermic circulatory arrest (MHCA) with a core temperature of 29 °C and bilateral selective antegrade cerebral perfusion in aTAAD treated by total arch replacement with stented elephant trunk implantation. METHODS From July 2019 to January 2020, 25 aTAAD patients underwent total arch replacement with stented elephant trunk implantation via MHCA (29 °C) and bilateral selective antegrade cerebral perfusion (modified group). Thirty-six patients treated by the same procedure with MHCA (25 °C) and unilateral selective antegrade cerebral perfusion during this period were selected as controls. RESULTS There were no differences between the two groups of patients in terms of age, sex, incidence of hypertension, malperfusion, and pericardial effusion, although the incidence of cardiac tamponade was higher in the modified group (control 2.8%, modified 20%; P = 0.038). The lowest mean circulatory arrest temperature was 24.6 ± 0.9 °C in the control group, and 29 ± 0.8 °C in the modified group (P < 0.001). In-hospital mortality was 4.9% (3/61) for the entire cohort (control 8.3%, modified 0; P = 0.262). The incidence of permanent neurologic deficit was 4.9% (control 8.3%, modified 0; P = 0.262). There were no significant differences in the occurrence of temporary neurological deficit, renal failure, and paraplegia between groups. The rate of major adverse events in the modified group was lower (30.6% vs. 4%, P = 0.019). A shorter duration of ventilation and ICU stay was identified in the modified group, as well as a reduced volume of drainage within the first 48 h and red blood cell transfusion. CONCLUSIONS The early results of MHCA (29 °C) and bilateral selective antegrade cerebral perfusion applied in total arch replacement with stented elephant trunk implantation for aTAAD were acceptable, providing similar inferior cerebral and visceral protection compared with that of the conventional strategy. A higher core temperature may account for the shorter duration of ventilation and ICU stay, as well as a reduced volume of drainage and red blood cell transfusion.

Abstract
BACKGROUND The aim of this study was to analyse the differences in renal function among various types of renal artery involvement in acute Debakey Type I aortic dissection. METHODS From January 2016 to January 2018, 304 consecutive patients with acute Debakey type I aortic dissection with renal artery involvement were included. According to computed tomography angiography (CTA) findings, renal artery involvement on one side can be classified into four types: type A, in which a large intimal tear is near the renal artery orifice; type B, the orifice of the renal artery originates entirely from the false lumen; type C, the orifice of the renal artery originates entirely from the true lumen; and type D, a renal artery dissection is observed. All patients underwent aortic repair. RESULTS The average age was 46.98±10.64 years. The types of bilateral renal artery involvement were as follows: AB type, four patients (1.32%); AC type, 38 patients (12.50%); AD type, three patients (0.99%); BB type, 13 patients (4.28%); BC type, 140 patients (46.05%); BD type, four patients (1.32%); CC type, 76 patients (25.00%); and CD type, 26 patients (8.55%). One-way ANOVA showed that there was no significant difference in serum creatinine (P = .57) and creatinine clearance rate (P = .08) between the groups. A statistically significant difference in age, gender, body mass index, hypertension history and aortic dissection onset time also was not observed (P > .05). The overall incidence of KDIGO acute kidney injury (AKI) was 49.67%. There was no significant difference in AKI incidence between different types of renal artery involvement after aortic surgery (P = .39). For patients needing renal replacement therapy, CTA showed that enhancement of renal cortex in the arterial phase was low and the boundary between the cortex and medulla was unclear in bilateral kidneys. CONCLUSION The types of renal artery involvement did not affect renal function in the acute phase.

Abstract
Objective: To evaluate long-term clinical outcomes of consecutive patients treated with coronary artery bypass grafting (CABG) and percutaneous coronary intervention(PCI) with drug-eluting stents(DES) for ostial/shaft lesions in unprotected left main coronary artery(ULMCA). Method: A total of 259 patients with isolated ostial/midshaft lesions in unprotected left main coronary artery were enrolled consecutively who received DES implantation or underwent CABG between January 2003 and July 2009 in Beijing Anzhen Hospital. The endpoints of the study were death, repeat revascularization, myocardial infarction (MI) and stroke. Time to the primary endpoint was evaluated according to the Kaplan-Meier method, and the log-rank test was applied to compare the incidence of the endpoint. Adjusted risks for adverse outcomes were compared by multivariate Cox proportional hazard regression analyses. Results: A total of 259 patients were included, including 149 in PCI group and 110 in CABG group. And 193(74.5%) cases were males.The age was (61.4±9.8) years old. The median follow-up was 10.1 years (interquartile range 8.3 to 11.2 years) in the overall patients. There were no significant difference for the incidence of death [37.0% vs. 43.1% ,P=0.143] , MI [34.0% vs. 19.4% ,P=0.866], stroke [6.4% vs. 11.7% , P=0.732], repeart revascularization [33.6% vs. 39.9% ,P=0.522] between PCI group and CABG group before multivariate adjusting,according to the incidence calculated with Kaplan-Meier. After adjusting covariates such as age, left ventricular ejection fraction(LVEF) and serum creatine with multivariate Cox hazard regression model, there was still no significant difference between the two groups. Conclusions: PCI with DES is as effective and safe as CABG in patients with left main ostium/shaft lesion during a median follow-up of 10.1 years.

Abstract
Background Stanford type A aortic dissection (STAAD) is a critical cardiovascular disease, and surgical procedure is the first-choice treatment. The classical surgical procedure still leads to a high mortality rate and neurological complications. In this study, we introduce a new modified Sun’s procedure and investigate the association between the branch-first technique and the postoperative outcomes of patients with STAAD. Methods A total of 108 consecutive patients with STAAD who underwent arch replacement and stent elephant trunk procedure at Beijing Anzhen Hospital between July, 2017 and November, 2018 were included in the analysis. The patients were divided into two groups: the branch-first group and the classic group. The branch-first group and the classic group comprised 24 patients (22.2%) and 84 patients (77.8%), respectively. Results Patients in the branch-first group had a significantly shorter cardiopulmonary bypass (CPB) duration (172.4±29.9 vs. 194.9±47.4 min; P=0.035), Intensive care unit (ICU) stay [17.0 (14.6–38.2) vs. 42.1 (19.7–87.2) hours; P<0.001], and mechanical ventilation time [15.5 (11.9–40.0) vs. 19.0 (17.0–45.6) hours; P=0.018] than patients in the classic group. The branch-first was associated with a reduction in postoperative neurological complications in all models. Conclusions The benefits of the branch-first technique, including lower CPB duration, better bilateral cerebral perfusion, and higher nasopharyngeal temperature during hypothermic arrest, contributed to a shortened recovery time for patients after surgery.

Abstract
Background Chronic type A aortic dissection (cTAAD) in Marfan syndrome (MFS) is rare. Surgical experience is limited and the role of frozen elephant trunk (FET) technique remains undefined. We seek to evaluate the safety and efficacy of the total arch replacement (TAR) and FET technique for cTAAD in MFS. Methods The clinical data of sixty-eight patients with MFS undergoing FET and TAR for cTAAD were analyzed. Results Mean age was 35.8±9.7 years and thirty-nine were male (57.4%). Operative mortality was 10.3% (7/68). Stroke occurred in one (1.5%), re-exploration for bleeding in five (7.3%), low cardiac output in four (5.9%), and acute renal failure in two (2.9%). Follow-up was complete in 100% (61/61) at mean 7.3±4.0 years. The false lumen was obliterated in 73.5% across FET and 50.0% in unstented descending aorta (DAo). Distal dilation occurred in twenty patients, six of whom underwent thoracoabdominal aortic replacement, one abdominal aortic replacement and one thoracic endovascular aortic repair (TEVAR). Late death occurred in five. At ten years, 59.8% were free from distal aortic dilation, and the incidences were 23.2% for death, 14.4% for distal reoperation, and 62.4% for reoperation-free survival. Predictors for operative mortality were extra-anatomic bypass [odds ratio (OR), 229.592; P=0.036], preoperative maximal size (DMax) of aortic sinuses (mm) (OR, 1.134; P=0.032) and cardiopulmonary bypass (CPB) time (minute) (OR, 1.061; P=0.041). Risk factors for aortic dilatation included patent false lumen at diaphragmatic hiatus [hazard ratio (HR), 5.374; P=0.008], preoperative DMax (mm) of proximal DAo (HR, 1.068; P=0.001) and renal arteries (HR, 1.102; P=0.005) which also predicted distal reoperation (HR, 1.149; P=0.001). The time from onset to operation (day) (HR, 1.002; P=0.004) and CPB time (minute) (HR, 1.032; P=0.036) predicted late death. Conclusions This study shows that the TAR and FET technique is a safe and durable approach to cTAAD in patients with MFS. The operation should be performed as early as possible to optimize clinical outcomes.

Abstract
BACKGROUND Cardiac reoperation has always been a difficult problem in clinical practice. Because of the difficulty of operation, the incidence of complications and mortality rate is high. Secondary aortic surgery, especially the reoperation involving arch, has higher risk and is more difficult for patients with renal failure. Sun's operation (total arch replacement + stent elephant nose) has achieved good results in the treatment of diseases involving aortic arch, and occupies an important position in the treatment of patients with secondary arch lesions after cardiac surgery. METHODS A total of 395 patients with a history of cardiac surgery were recorded in our center from January 1, 2009 to December 31, 2017, among whom 118 (30.1%) patients underwent aortic reoperation via the original incision using Sun's aortic procedure owing to postoperative great vessel disease. We analyzed the clinical data and survival time, and used Cox regression to analyze the risk factors for 30-day mortality as well as long term mortality. RESULTS The interval between the last operation and the present operation was 0.08-19 years. Sixteen patients died within 30 days after operation and the average mortality rate was 13.6%. During the follow-up period, 28 patients died, with the mortality rate of 23.7%. As of December 31, 2017, the longest survival time was 9.36 years, and the survival time of 70 patients was more than 3.05 years. The main risk factor associated with the 30-day survival was cardiopulmonary bypass (CPB) time. The longer the CPB time was, the greater the risk of death was. The main risk factors associated with the long-term survival were CPB time and 24-h bleeding volume. The longer the CPB time was, the more the 24-h bleeding volume was, the higher long-term mortality rate was. CONCLUSION The second Sun's operation, as a surgical treatment after cardiac surgery, showed a high survival rate, with long survival time and good curative effect. CPB is the main risk factor for the 30-day survival state after operation, and CPB time and 24-h bleeding volume are the main risk factors for the long-term survival state after operation.

Abstract
BACKGROUND Acute type A aortic dissection (ATAAD) is a life-threatening condition that requires surgical intervention. Stroke remains an extremely serious adverse outcome that can occur in ATAAD patients undergoing aortic arch repair, leading to higher rates of patient mortality and decreased postoperative quality of life. In the present study, we sought to determine whether carotid intima-media thickness (cIMT) is a reliable predictor of postoperative stroke risk. MATERIALS AND METHODS This was a prospective study of 76 patients with ATAAD undergoing aortic arch repair. For all patients, cIMT was determined preoperatively through a Doppler-based method. Incidence of different forms of neurological dysfunction, including temporary neurological dysfunction (TND) and stroke, was monitored in these patients, and the relationship between cIMT and stroke incidence was assessed using a receiver-operating characteristic (ROC) curve. Prognostic variables associated with stroke risk were further identified through univariate and multivariate analyses. RESULTS A total of 26/76 (34.2%) patients in the present study suffered from neurological dysfunction, of whom 16 (21.0%) suffered from TND and 10 (13.2%) suffered a stroke. The remaining 50 patients (65.8%) did not suffer from neurological dysfunction. The cIMT values in the stroke, TND, and neurological dysfunction-free patients in this study were 1.12 ± 0.19 (mm), 0.99 ± 0.13 (mm), and 0.87 ± 0.13 (mm), respectively. A total of 4 patients in this cohort died during the study, including 1 in the TND group and 3 in the stroke group. An ROC curve analysis indicated that cIMT could predict stroke with an area under the curve value of 0.844 (95% CI, 0.719-0.969; p < 0.001). A multivariate analysis revealed that cIMT > 0.9 mm was independently associated with stroke risk (p = 0.018). CONCLUSION We found that cIMT can be used to predict postoperative stroke risk in ATAAD patients undergoing aortic arch repair, with a cIMT > 0.9 mm coinciding with increased stroke risk in these patients. TRIAL REGISTRATION ChiCTR1900022289. Date of registration 4 April 2019 retrospectively registered.

Abstract
Abstract
OBJECTIVES
Pregnancy-related aortic dissection (AoD) in Marfan syndrome is a lethal catastrophe. Due to its rarity and limited clinical experience, there is no consensus regarding the optimal management strategy. We seek to present our 21-year experience in such patients , focusing on management strategies and early and late outcomes.
METHODS
Between 1998 and 2019, we managed 30 pregnant women with Marfan syndrome (mean age 30.7 ± 4.3 years) who sustained AoD at a mean of 28.3 ± 8.8 weeks of gestation (GWs). AoD was acute in 21 (70%), type A (TAAD) in 24 (80%) and type B (TBAD) in 6 (20%). Fourteen TAADs (58.3%, 14/24) and 2 TBADs (33.3%, 2/6) occurred in the third trimester or postpartum. The maximal aortic size was < 45 mm in 26.7% (8/30; 3 TAADs, 5 TBADs). Management strategy was based on the types of dissection and GWs (i.e. surgical versus medical treatment, surgery or delivery first).
RESULTS
TAADs were treated medically in 1 and surgically in 23. The timing of delivery and surgery were caesarean first at 35.4 ± 6.1 GWs in 7 (29.2%), followed by surgery after mean 46 days; single-stage C-section and surgery at 32.0 ± 5.0 GWs in 10 (41.7%); and surgery first at 18.0 ± 5.8 GWs in 6 (25%), followed by C-section after 20 days. Maternal and foetal mortality were 28.6% (2/7) and 14.3% (1/7), 10.0% (1/10) and 20.0% (2/10) and 16.7% (1/6) and 83.3% (5/6), respectively. Five TBADs (83.3%) were managed with C-section followed by surgery in 2 and medical treatment in 3. The respective maternal and foetal mortality were 50% (1/2) and 100% (2/2) and 33.3% (1/3) and 33.3% (1/3), respectively. One TBAD was managed surgically first followed by C-section, resulting in maternal survival and foetal death. Follow-up was complete in 95.8% (23/24) at 3.7 ± 2.9 years. Four late deaths occurred and reoperation was performed in 1 patient. Maternal and foetal survival were 64.3% and 54.1% at 6 years, respectively.
CONCLUSIONS
Management of AoD in pregnant women with Marfan syndrome should be based on types of dissection (surgical versus medical) and gestational age (delivery or surgery first), which largely determine maternal and foetal survival. Aortic repair should be considered prior to conception in women with Marfan syndrome even at diameters smaller than recommended by current guidelines.

Abstract
Background Aortic intramural hematoma is a life-threatening condition reported with increasing frequency. It can be classified into Stanford type A or B depending on whether the ascending or descending aorta are involved, respectively. However, the onset of acute type A aortic dissection following recovery of type B intramural haematoma is rarely reported. Case presentation We present an uncommon case of acute Stanford type A aortic dissection developing 3 months after recovery of type B IMH in a 47-year-old female. She complained acute chest pain. The operation was successfully done. She was in good condition and asymptomatic at a 3-month follow-up. Conclusions Type B intramural haematoma can lead to type A aortic dissection even after totally absorbed and the primary entry has the potential to be located in the ascending aorta. Unsatisfied blood pressure control may be the underlying cause.

Abstract
Erythropoietin-producing hepatomocellular receptors and their receptor-interacting proteins (Eph/ephrin) can participate in the regulation of growth and development and promote the development of diseases through short-distance signal transduction between cells. To study the mechanism of Eph/ephrin and oral-related diseases, we provided a new theoretical basis and a strategy for the treatment of oral diseases. The Eph/ephrin pathway has been used to regulate oral diseases, especially in periodontal disease prevention, orthodontic bone reconstruction, and biological treatment of oral tumors. This paper reviews the research progress of Eph/ephrin pathway in oral-related diseases.

Abstract
BACKGROUND Type Ia endoleaks are common after thoracic endovascular aortic repair (TEVAR). However, the repair of type Ia endoleaks involving the distal arch is challenging because of the presence of the interventional endografts, potential damage to the aortic arch vessels, and the location and size of the aneurysmal body. We retrospectively reviewed our experience of the surgical treatment of type Ia endoleaks with distal arch involvement using left subclavian artery (LSCA)-left common carotid artery (LCCA) transposition with a stented elephant trunk. METHODS Sixteen patients (male = 16; mean age, 47 ± 9 years, range 31-63 years) with type Ia endoleaks involving the distal arch underwent LSCA-LCCA transposition with a stented elephant trunk from July 2010 to July 2018. TEVAR failure occurred in 12 patients, re-TEVAR was performed in two patients, hybrid aortic arch repair in one patient, and the chimney technique in one patient. RESULTS There were no in-hospital deaths. Fourteen patients required mechanical ventilation for <24 h and one for <48 h. One patient required reintubation after mechanical ventilation for 19 h and continuous renal replacement therapy because of renal failure. One patient received pericardial drainage, and recurrent laryngeal nerve injury occurred in one patient. Three patients died during follow-up. CONCLUSIONS The LSCA-LCCA transposition with a stented elephant trunk can produce satisfactory results in patients with a type Ia endoleak involving the distal arch. Using this technique, it is possible to exclude the aneurysm sac distal to the LCCA origin and seclude the failed interventional endograft. These encouraging outcomes suggested that this technique could be a suitable surgical treatment for this type of lesion.

Abstract
Abstract
OBJECTIVES
Aortic dissection (AoD) in the presence of an aberrant right subclavian artery (ARSA) is very rare. Clinical experience is limited, and there is no consensus regarding the optimal management strategy. We seek to evaluate the safety and efficacy of the total arch replacement (TAR) and frozen elephant trunk (FET) technique as an approach to AoD in patients with ARSA by retrospectively analysing our single-centre experience.
METHODS
From 2009 to 2017, we performed TAR + FET for 22 patients with ARSA sustaining AoD (13 acute, 59.1%). The mean age was 46.0 years [standard deviation (SD) 8.3], and 19 patients were male (86.4%). ARSA orifice was dilated in 15 (68.2%) patients, and a Kommerall diverticulum was diagnosed in 13 (59.1%) patients with a mean diameter of 21.8 mm (SD 7.7; range 15–40). Surgery was performed via femoral and right/left carotid cannulation under hypothermic circulatory arrest at 25°C. The ARSA was reconstructed using a separate branched graft.
RESULTS
ARSA was closed proximally by ligation in 16 (72.7%) patients, direct suture in 4 (18.2%) patients and both in 2 (9.1%) patients. Operative mortality was 13.6% (3/22). Type Ib endoleak occurred in 1 (4.5%) patient at 8 days. Follow-up was complete in 100% at mean 4.2 years (SD 2.0), during which 3 late deaths and 1 reintervention for type II endoleak occurred. Survival was 81.8% and 76.4% at 3 and 5 years, respectively. Freedom from reoperation was 89.2% up to 8 years. In competing risks analysis, the incidence was 22.1% for death, 10.8% for reoperation and 67.1% for event-free survival at 5 years. The false lumen, ARSA orifice and Kommerall diverticulum were obliterated in 100%. Grafts were patent in 100%. No patients experienced cerebral ischaemia and upper extremity claudication. Hypothermic circulatory arrest time (min) was sole predictor for death and aortic reintervention (hazard ratio 1.168, 95% confidence interval 1.011–1.348; P = 0.034).
CONCLUSIONS
The TAR and FET technique is a safe and efficacious approach to AoD in patients with ARSA. Modifications of routine TAR + FET techniques are essential to successful repair, including femoral and right/left carotid artery cannulation, ligation of ARSA on the right side of the trachea and ARSA reconstruction with a separate graft.

Abstract
BACKGROUND In the design and development of small-caliber artificial blood vessels, endothelialization is a key issue, but it is not well understood at present. Some studies have used vascular endothelial growth factor (VEGF) sustained-release methods to promote endothelial cell proliferation. However, this method is not ideal. This study has used drugs to induce endothelial cells to produce VEGF. This method in turn functions to promote cell proliferation and promote the endothelialization of artificial blood vessels. This study aimed to investigate the effect of the antiplatelet drug tirofiban on endothelial cell proliferation in vitro. METHODS In this study, human umbilical vein endothelial cells (HUVECs) were used to determine the effect of tirofiban-stimulated cell proliferation. Analysis of cell proliferation, assayed by the Cell Counting Kit-8 assay, showed that the number of cells was increasingly higher than in the absence of tirofiban. It was also observed that heparin enhanced the tirofiban effect. The cell VEGF expression at different time points after tirofiban addition was detected by western blot analysis. RESULTS The absorbance values of the experimental (1 μg/mL tirofiban) and the control groups (0 tirofiban) were 1.74 (SD, 0.03) and 1.51 (SD, 0.07) (P < .001), respectively, after 4 days of culture under the same conditions. The amount of VEGF produced by HUVECs gradually increased after treatment with tirofiban, reached a peak at 2 hours, and was 1.3-fold greater than the control group (P = .034). Compared with the tirofiban-only group, the absorbance value of the tirofiban and 10 μg/mL of heparin group was significantly increased (P < .001). CONCLUSIONS Tirofiban promoted the proliferation of HUVECs by promoting the synthesis of VEGF in HUVECs. Heparin enhanced tirofiban activity in promoting HUVEC proliferation.

Abstract
BACKGROUND The purpose of this study was to examine whether chronologic and climatic factors and lunar phases affect the onset of acute aortic dissection (AAD). METHODS The frequencies of AAD were analyzed with regard to the chronologic and climatic factors and lunar phases on the day when AAD occurred for 1642 patients with AAD from two aortic referral centers in the United States and China. RESULTS Mean age of patients was 51.6 ± 13.1 years, and 1260 (76.7%) were men. Dissection was type A in 1125 patients (68.5%) and type B in 517 (31.5%). Early mortality rate was 11.6% (190 of 1642), including 89 aortic ruptures before operation and 101 operative deaths. There was a winter peak in occurrence (33.6%, P < .01) with a relative risk of 1.519. In a week, the frequency was highest on Wednesday (15.5%) and Monday (15.2%), and lowest on Sunday (12.8%). Month-specific incidence was significantly inversely correlated to the mean temperature (rho = -0.650, P = .022) and directly correlated to the atmospheric pressure (rho = 0.706, P = .001). The proportion of type A dissection was significantly higher in the full moon phase compared with type B dissection (73.7% vs 66.9%, P = .012). CONCLUSIONS Acute aortic dissection exhibits significant chronologic variation in the frequency of occurrence, with a peak in winter and on Wednesdays, and nadir in summer and on Sundays. The incidence is significantly correlated to the mean temperature and atmospheric pressure. The proportion of type A dissection is higher in the full moon phase. These results are important for understanding the mechanisms involved in triggering AAD events and helpful for improving disease prevention and patient care.

Abstract
BACKGROUND Aortic dissection during pregnancy is a rare but life-threatening event for mothers and fetuses. It often occurs in the third trimester of pregnancy and the postpartum period. Most patients have connective tissue diseases such as Marfan syndrome. Thus, the successful repair of a sporadic aortic dissection with maternal and fetal survival in the early second trimester is extremely rare.
CASE SUMMARY A 28-year-old woman without Marfan syndrome presented with chest pain at the 16th gestational week. Aortic computed tomographic angiography confirmed an acute type A aortic dissection (TAAD) with aortic arch and descending aorta involvement. Preoperative fetal ultrasound confirmed that the fetus was stable in the uterus. The patient underwent total arch replacement with a frozen elephant trunk using moderate hypothermic circulatory arrest with the fetus in situ. The patient recovered uneventfully and continued to be pregnant after discharge. At the 38th gestational week, she delivered a healthy female infant by cesarean section. After 2.5 years of follow-up, the patient is uneventful and the child’s development is normal.
CONCLUSION A fetus in the second trimester may have a high possibility of survival and healthy growth after aortic arch surgery.

Abstract
OBJECTIVE Cervical aortic arch (CAA) is rare and difficult to repair. Clinical experience is limited. We report the surgical techniques and midterm outcomes in 35 patients with CAA based on an alternative classification scheme. METHODS Of 35 patients with CAA, 30 (85.7%) had left-sided aortic arch and 5 had (14.3%) right-sided aortic arch (all 5 had a vascular ring). Mean age was 34.2 ± 13.1 years, 23 were female (65.7%), and 18 were asymptomatic (51.4%). Surgical access and procedure were chosen according to an alternative classification scheme that is based on the presence or absence of vascular ring and relationship of descending aorta to the side of the aortic arch. In the left-sided aortic arch group, aortic arch reconstruction though median sternotomy was performed in 15 patients, and distal arch and descending thoracic aortic replacement via left thoracotomy in 15 patients. In the right-sided aortic arch group, ascending-to-descending aortic bypass was done via median sternotomy in 2 patients and right thoracotomy in 1, and distal arch and descending thoracic aortic replacement via right thoracotomy in 2 patients. RESULTS Neither death nor spinal cord injury occurred. Left recurrent laryngeal nerve injury, prolonged ventilation, and reexploration for bleeding occurred in 1 each. In 11 patients with coarctation, the upper-lower limb gradient decreased significantly postoperatively (from 34.0 ± 12.7 to 10.2 ± 2.7 mm Hg; P < .01). The diseased aortic segment was excluded in 34 patients, except 1 with residual aneurysm in the proximal descending thoracic aorta. Follow-up was complete in 100% at mean 4.4 ± 2.0 years. No late death, limb ischemia, or stroke occurred. Endovascular repair was performed in 1 patient, and ascending aortic dilation occurred in 1 patient. The residual aorta remained nondilated in 33 patients. Aortic grafts were patent in 100%, with no anastomotic leak or pseudoaneurysm. At 6 years, the incidences of death, aortic events, and event-free survival were 0%, 6.5%, and 93.5%, respectively. CONCLUSIONS Open repair of CAA can achieve favorable early and midterm outcomes. Surgical accesses and procedures should be chosen based on type of CAA, anatomic variations and associated anomalies. Our alternative categorization scheme of CAA is intuitive and comprehensive, which may facilitate classification and surgical decision making.

Abstract
Graft aneurysm after ascending aorta to abdominal aorta bypass is a rare complication of repair of coarctation of the aorta. We present a case of an aneurysm measuring 75 mm in diameter at the midportion of the prosthetic graft in a 33-year-old man. To prevent aneurysm rupture, redo ascending-to-abdominal aortic bypass was performed through an upper ministernotomy and upper midline laparotomy. No postoperative complications occurred. The patient was successfully discharged on postoperative day 6. Although ascending-to-abdominal aortic bypass can achieve long-term patency, the prosthetic graft still has the rare risk of aneurysm formation, as highlighted in this case. Early diagnosis and timely management of this rare complication are essential in preventing aneurysm rupture.

Abstract
Abstract
OBJECTIVES
To study the perioperative outcomes and long-term survival rates in patients undergoing thoracic endovascular aortic repair (TEVAR) for uncomplicated type B dissection.
METHODS
A total of 751 patients with uncomplicated type B dissection who underwent TEVAR at our centre between May 2001 and December 2013 were retrospectively reviewed. The mean age of all patients (619 males and 132 females) was 52.8 ± 10.9 years. The follow-up period ranged from 1 to 170 months (median 70 months).
RESULTS
Five patients died during the perioperative period (mortality rate 0.7%). Four patients (0.5%) developed retrograde type A dissection. Two patients (0.3%) developed paraplegia and 1 patient developed incomplete paralysis (0.1%). There were no postoperative cerebral infarctions. The 5- and 10-year survival rates were 96.5% [95% confidence interval (CI) 95.0–98.0%] and 83.0% (95% CI 77.9–88.4%), respectively. The 5- and 10-year reintervention rates were 4.6% (95% CI 3.0–6.2%) and 7.9% (95% CI 5.3–10.5%), respectively.
CONCLUSIONS
Although the application of TEVAR for patients with uncomplicated dissection is still under debate, many patients who have undergone TEVAR have benefitted substantially from the treatment. Our data showed that TEVAR had low mortality and complication rates both in the short- and long-term follow-up periods. TEVAR may be considered as a first choice for patients with uncomplicated type B dissection.

Abstract
BACKGROUND To evaluate one-stage repair with ascending to abdominal aorta extra-anatomical bypass combined with cardiac surgery for adult aortic coarctation (COA) concomitant with cardiac diseases. METHODS Between February 2009 and September 2016, 24 consecutive patients (79.17% male, mean age 36.04±13.67years) with COA and concomitant cardiac diseases underwent one-stage repair (ascending to abdominal aorta extra-anatomical bypass combined with cardiac surgery). Two (2) patients who underwent off-pump coronary artery surgery combined with ascending to abdominal aorta bypass did not require cardiopulmonary bypass. Twenty-two (22) patients underwent one-stage repair under cardiopulmonary bypass. RESULTS No in-hospital mortality was observed. There was a significant reduction in baseline systolic blood pressure from 159.80±23.58 to 127.0±6.86mmHg. Mean upper-lower limb blood gradient pressure decreased significantly from 37.80±8.73 to 11.47±2.12mmHg after surgery. Two (2) patients required prolonged mechanical ventilation for respiratory dysfunction. One patient needed temporary continuous renal replacement therapy. No re-exploration for bleeding and gastrointestinal complications was needed. There was no postoperative paraplegia or permanent neurological abnormalities. Grafts were patent for all patients and no graft-related complications were observed in the hospital. Median follow-up was 41.50 months (interquartile range [IQR] 16.75-64.50 months) and 6-year survival was 76.39%. Median number of antihypertensive drugs was 0 (IQR 0-1), which was a significant reduction compared with preoperative drugs (2, IQR 1-3). CONCLUSIONS Ascending to abdominal extra-anatomical aorta bypass combined with cardiac surgery is a safe and effective one-stage repair technique for patients with COA concomitant with cardiac diseases.

Abstract
Objective: To explore the clinical and pathological features and mutational types and their relations with WT1 mutation-associated nephropathy (WT1MAN). Methods: The clinical and pathological data and the results of WT1 mutation analysis of the cases from Nanfang Hospital of Southern Medical University, Sun Yat-sen Memorial Hospital and The First Affiliated Hospital of Sun Yat-sen University whom we recruited recently and reported during the last ten years were analyzed. Results: Totally, 20 cases (6 males and 14 females), included 5 newly diagnosed cases, were recruited. (1) Ten children were diagnosed with Denys-Drash syndrome (DDS): The median onset age of proteinuria was 1 year and 7 months. Diffuse mesangial sclerosis (DMS) were revealed in 3 cases, minimal lesions (MCD) in 4 cases, and focal segmental glomerulosclerosis (FSGS) in 1 case; renal pathology was not available in the other 2 cases. Glomerular basement membrane (GBM) thickening was observed in 2 cases. Calcineurin inhibitors (CNIs) were administered in 5 cases, complete remission of proteinuria was observed in 3 cases, partial remission in the other 2 cases. Genetic analysis revealed that six cases had WT1 missense mutation, 3 had nonsense mutation, and 1 had frameshift mutation. (2) Two cases were diagnosed with Frasier syndrome (FS): proteinuria was observed at 1 year and 1 month of age and 1 year and 9 months of age, respectively. FSGS with GBM layering were observed in both cases. They progressed to ESRD at 1 year and 6 months of age and 6 years and 6 months of age, respectively. CNI was tried in 1 case with partial proteinuria remission. Both patients were detected to have WT1 splice mutation. (3) Isolated nephropathy (IN) was observed in 8 cases: three had splice mutation, 5 had missense mutation. Of the 3 patients with splice mutation, one was found to have nephropathy and renal failure at the age of 5 months. The other two cases (1 was FSGS and another MCD), both had GBM layering. CNIs were tried on both of them, one got partial remission with normal renal function at the age of fourteen years, the other one had no response and entered ESRD at the age of 6 years and 9 months. Of the 5 cases with missense mutation, 3 had DMS, 2 of them entered ESRD within 6 months of age, another case had DMS entered ESRD at 9 years of age. One case with FSGS, was treated with CNIs and got complete remission. Conclusions: Slow progression (7/10) nephropathy was observed in DDS patients. Missense mutation (11/20) was the most common type of WT1 variants, followed by splice mutation (5/20) in this group of patients. Early onset nephropathy (4/5), rapid progression (4/5) and GBM layering (4/4) wereobserved in patients with splice mutation. CNI was effective in reducing or even eliminating proteinuria in WT1 MAN patients (8/9).

Abstract
Background Several methods of arch vessel reconstruction, such as en bloc (island) and branched graft techniques, have been proposed to treat aortic arch pathologies during total arch replacement (TAR). We seek to review our experience with modified en bloc technique and left subclavian (LSCA)-left carotid artery (LCCA) transposition in TAR and frozen elephant trunk (FET) procedure for chronic type A aortic dissection (CTAAD). Methods From September 2010 to September 2016, 35 consecutive patients with CTAAD underwent modified en bloc arch reconstruction with LSCA-LCCA transposition during TAR and FET procedure. Computed tomographic angiography (CTA) was performed during follow-up. Results In-hospital mortality was 5.7% (2/35). No neurological deficit or spinal cord injury occurred. Re-exploration for bleeding and continuous renal replacement therapy were required in 2 patients each (5.7%). Follow-up was complete in 100% for a mean duration of 4.1±1.8 years (range, 0.5-6.7 years). One patient experienced a transient stroke and thoracoabdominal aortic replacement was performed in 1. There were 2 late non-cardiac deaths. Survival was 87.9% (95% CI, 70.7-95.3%) at 6 years. At 6 years, the incidence was 3% for reoperation, 12% for late death, and 85% of patients were alive without reoperation. The anastomosis between the LSCA and LCCA was patent in 100%. Conclusions Acceptable early and mid-term outcomes were achieved for patients with chronic type A dissection using en bloc technique with LSCA-LCCA transposition during TAR and FET procedure. This technique may be an alternative approach to chronic type A dissection in selected patients.

Abstract
Background We seek to report the long-term outcomes of the total arch replacement and frozen elephant trunk (TAR + FET) technique for type A aortic dissection (TAAD) following prior Bentall procedure in patients with Marfan syndrome (MFS). Methods Between 2003 and 2015, we performed TAR + FET for 26 patients with MFS who developed TAAD following a prior Bentall procedure. Mean age at FET 36.9±9.7 years and 24 were males. TAAD was acute in 8 (30.8%, all new dissections from precious root aneurysm) and chronic in 18 (69.2%, 15 residual and 3 new). The interval from Bentall procedure to FET averaged 6.4±5.8 years, which was significantly longer in the acute group (10.3±6.3 vs. 4.6±4.9, P=0.021). The early and long-term outcomes were compared between two groups and risk factors identified for late adverse events. Results Operative mortality was 11.5% (3/26). Stroke, lower limb ischemia and reexploration for bleeding occurred in 1 patient each (3.8%). Follow-up was complete in 100% (23/23) at mean 5.1±2.3 years (range, 0.9-11.2 years). The maximal diameter (DMax) of distal aorta in the chronic group was significantly greater at the unstented descending aorta [DA, (56.4±15.5 vs. 35.6±12.2 mm, P=0.006)] compared to acute patients. The false lumen was obliterated in 95.7% across the FET and 56.5% in the unstented DA. Distal aortic dilation occurred in 13 patients (11 chronic, 68.8%). Of those 11 patients, 4 underwent an open thoracoabdominal aortic repair and 3 died of distal aortic rupture. Late death occurred in 7 patients at mean 3.9±2.5 years. At 6 years, the incidence was 18% for death, 11% for distal aortic reoperation, and 71% for reoperation-free survival. Survival did not differ between two groups (75.0% vs. 71.3%, P=0.851), while acute patients had significantly higher freedom from late rupture and reoperation at 6 years (100% vs. 61.9%, P=0.046). Hypertension was the sole risk factor for distal aortic dilatation [hazard ratio (HR) =7.271; 95% confidence interval (CI), 1.814-29.143; P=0.005]. Risk factors for late adverse events were hypertension (HR =6.712; 95% CI, 1.201-37.503; P=0.030) and age <35 years (HR =6.760; 95% CI, 1.154-39.587; P=0.034). Conclusions The TAR and FET technique was feasible and efficacious for TAAD following previous Bentall procedure in patients with MFS. Early and late survival did not differ with acute and chronic dissections, while freedom from late rupture and reoperation is significantly higher in patients with acute TAAD. Patients with hypertension and aged <35 years are at higher risk for late distal aortic dilation, reoperation and death.
