Introduction: Type A acute aortic dissection (TA-AAD) is a great challenge for aortic surgeons. The establishment of a standardized surgical approach, particularly the determination of whether and when to address the aortic arch and the distal aorta in the same operation as the proximal aorta, is still unclear., Areas Covered: Frozen elephant trunk (FET) has emerged as a valuable treatment for TA-AAD over the last decade. Here, we discuss the fundamentals and pitfalls of frozen elephant trunk procedures and present the latest innovations., Expert Opinion: FET has the potential to simplify arch reconstruction in patients with complex arch tears and rupture, optimize perfusion in the distal true lumen for those with a compressed true lumen and malperfusion, address distal reentry tears, and promote false lumen thrombosis and late aortic remodeling. Nevertheless, FET is still associated with non-negligible mortality and morbidity rates. Patient selection, surgical expertise, and postoperative care remain crucial determinants in ensuring successful outcomes. Recent innovations in FET surgery involve the development of techniques to minimize or avoid hypothermic circulatory arrest and new FET devices with different arch branch configurations aiming to facilitate subsequent aortic reinterventions. We believe that both these advancements have the potential to improve patient outcomes.

Background: Enhanced recovery after surgery (ERAS) protocols aim to reduce postoperative complications and promote earlier recovery. Although it is well established in noncardiac surgery fields, the ERAS approach has only recently been adopted in cardiac surgery. The aim of this review is to evaluate the status and implementation of ERAS protocols in patients undergoing heart valve surgery and to summarise associated clinical results. Methods: A literature search for the period January 2015 and January 2024 was performed through online databases. Clinical studies (randomised controlled trials and cohort studies) on patients undergoing heart valve surgical procedures and comparing ERAS and conventional approaches were included. The data extracted covered studies and populations characteristics, early outcomes and the features of each ERAS protocol. Results: There were 14 studies that fulfilled the final search criteria and were ultimately included in the review. Overall, 5142 patients were identified in the 14 studies, with 2501 in ERAS groups and 2641 patients who were representative of control groups. Seven experiences exclusively included patients who underwent heart valve surgery. Twelve out of fourteen protocols involved multiple interventions from the preoperative to postoperative phase, while two studies reported actions limited to intraoperative and postoperative care. We found high heterogeneity among the included protocols regarding key actions targeted for improvement and measured outcomes. All the studies showed that ERAS pathways can be safely adopted in cardiac surgery and in most of the experiences were associated with shorter mechanical ventilation time, reduced postoperative opioid use and reduced ICU and hospital stays. Conclusions: As demonstrated in noncardiac surgery, the adoption of structured ERAS protocols has the potential to improve results in patients undergoing heart valve surgery. Further evidence based on larger populations is needed, including more homogenous pathways and reporting further outcomes in terms of patient satisfaction, recovery and quality of life after surgery.

Objective: In heritable aortic diseases, different vascular involvement may occur with potential variable implications in aortic dilation/dissection risk. This study aimed to analyze the aortic anatomy of individuals with Marfan syndrome and Loeys-Dietz syndrome to identify possible morphological differences., Methods: Computed tomography and magnetic resonance imaging of the thoracoabdominal aorta from the proximal supra-aortic vessels to the femoral bifurcation level of 114 patients with Marfan and Loeys-Dietz syndromes and 20 matched control subjects were examined. Aortic diameters, areas, length, and tortuosity were measured in different aortic segments using specific vessel analysis software., Results: Patients with Marfan syndrome showed a higher prevalence of ascending aorta and aortic root dilation ( P  = .011), larger and longer aortic roots ( P  = .013) with pear-shaped phenotype, larger isthmus/descending aorta diameter ratio ( P  = .015), and larger suprarenal aorta and iliac arteries. Patients with Loeys-Dietz syndrome showed longer indexed segments and a significantly longer arch ( P  = .006) with type 2/3 arch prevalence ( P  = .097). Measurement ratios analysis provided cut-off values (aortic root to ascending aorta length/aortic root diameter, aortic root/sinotubular junction, aortic root/ascending aorta diameter) differentiating patients with Marfan syndrome from patients with Loeys-Dietz syndrome, even in the early stage of the disease., Conclusions: Both syndromes show peculiar anatomic patterns at different aortic levels irrespective of aortic dilation and disease severity. These features may represent the expression of different genetic mutations on aortic development, with a potential impact on prognosis and possibly contributing to better management of the diseases. The systematic adoption of whole body imaging with magnetic resonance or computed tomography should always be considered, because they allow a complete vascular assessment with practical indicators of differential diagnosis., Competing Interests: The authors reported no conflicts of interest.

Background and Objectives : Minimally invasive cardiac surgery is an established approach for the treatment of heart valve pathologies and is associated with excellent technical and early postoperative outcomes. Data from medium- and long-term longitudinal evaluation of patients who underwent mitral valve repair (MVr) through transaxillary approach (TAxA) are still lacking. The aim of this study is to investigate mid-term results in patients who underwent TAxA MVr. Materials and Methods : Prospectively collected data of patients who underwent first-time MVr for MV regurgitation between 2017 and 2022, were reviewed. A total of 308 patients received TAxA, while in 220 cases, traditional full sternotomy (FS) was performed. Concomitant aortic and coronary artery bypass grafting (CABG) procedures, infective endocarditis or urgent operations were excluded. A propensity match (PS) analysis was used to overcome preoperative differences between the populations. Follow-up data were retrieved from outpatients' clinic, telephone calls and municipal administration records. Results : After PS-matching, two well-balanced cohorts of 171 patients were analysed. The overall 30-day mortality rate was 0.6% in both cohorts. No statistical difference in postoperative complications was reported. TAxA cohort experienced earlier postoperative extubation ( p < 0.001) with a higher rate of extubation performed in the operating theatre ( p < 0.001), shorter intensive care unit (ICU) stay ( p < 0.001), and reduced hospitalization with 51% of patients discharged home ( p < 0.001). Estimated survival at 5 years was 98.8% in TAxA vs. 93.6% in FS cohort (Log rank p = 0.15). The cumulative incidence of reoperation was 2.6% and 4.4% at 5 years, respectively, in TAxA and FS cohorts (Gray test p = 0.49). Conclusions : TAxA approach for MVr was associated with low rates of in-hospital mortality and major postoperative complications being furthermore associated with shorter mechanical ventilation time, shorter ICU stay and reduced hospitalization with a higher rate of patients able to be discharged home. At mid-term, TAxA was associated with excellent survival and low rate of MV reoperation.

Surgical aortic valve replacement (SAVR) in female patients has been associated with higher mortality (up to 3.3-8.9%) and postoperative complication rates when compared with their male counterparts. In recent years, TAVI has been shown to provide a greater benefit than SAVR in women. We sought to assess the early outcomes of the contemporary aortic valve intervention practice (surgical and transcatheter) in patients referred to our cardiac surgery unit. The data of consecutive patients who underwent isolated aortic valve intervention for aortic valve stenosis during the 2018-2022 period were retrieved from our internal database. Several preoperative, intraoperative, and postoperative variables were analyzed, including the predicted risk of a prosthesis-patient mismatch. Nine hundred and fifty-five consecutive patients-514 women and 441 men-were included. Among them, 480 patients-276 female and 204 male-received a transcatheter procedure, and 475-238 women and 237 men-had conventional SAVR. The women were older and had higher EuroSCORE II, while the male patients presented a higher incidence of cardiovascular comorbidities. There was no difference in mortality or major postoperative complication rates after either the surgical or transcatheter procedures between the female and male populations. The availability and targeted use of different techniques and technologies have enabled the safe and effective treatment of female patients treated for severe symptomatic aortic valve stenosis with similar results when compared with their male counterparts.

Objectives: Current evidence on transcatheter aortic valve implantation (TAVI) has been generated exclusively by cardiology studies and no operative data from cardiac surgeons are available. Here, we describe the development of our TAVI programme and report the results of transfemoral (TF) TAVI done by cardiac surgeons on their own., Methods: This study included all the TAVI procedures on native valve performed at Cardiac Surgery Unit, Ospedali Riuniti di Ancona, during the period October 2018 to July 2022. Relevant prospectively collected preoperative, intraprocedural and postoperative data were retrieved from the Institutional database., Results: A total of 413 patients were included in the study. Mean patients' age was 82 years and among them 44% (180/413) were male. STS score was 3.1% (2.2-4.4). Eighty patients underwent transapical TAVI and 333 patients had a TF approach. We progressively moved from transapical TAVI towards TF procedures that are now routinely performed on conscious sedation and using a fully percutaneous approach. After TF TAVI, 30-day mortality rate was 1%, cerebral stroke occurred in 2% of the cases, permanent pacemaker implantation was necessary in 23% of the patients and in 6% of the cases there was a moderate/severe degree of aortic regurgitation. There was no association between operators performing TAVI and 30-day mortality., Conclusions: The acquisition of catheter-based skills and an adequate training allowed cardiac surgeons to perform on their own awake and fully percutaneous TF TAVI with similar results when compared with major randomized clinical trials and registries' experiences., (© The Author(s) 2023.

Background and Objective: The frozen elephant trunk (FET) technique has undoubtable advantages in treating complex and extensive disease of the aortic arch and the thoracic descending aorta. Despite several improvements in cardiopulmonary bypass conduction and surgical strategy, operative times and the institution of systemic circulatory arrest remain the main determinants of early mortality, cerebral/spinal cord injury and visceral organs dysfunction. We have conducted this review to highlight the recent technical advances in arch and FET surgery aiming at the reduction/avoidance of systemic circulatory arrest, and their impact on early outcomes., Methods: A literature search (from origin to January 2022), limited to publications in English, was performed on online platforms and database (PubMed, Google, ResearchGate). After a further review of associated or similar papers, we found 4 experiences, described by 11 peer-reviewed published papers, which focused on minimising or avoiding systemic circulatory arrest during total arch replacement plus stenting of the descending thoracic aorta., Key Content and Findings: Recent experiences reported the use of an antegrade endoaortic balloon, advanced and inflated into the stent graft, to provide an early systemic reperfusion soon after the deployment of the stented portion of the FET prosthesis and minimize the circulatory arrest time (down to a mean of 5 minutes), thus avoiding the need of moderate or deep hypothermia (mean systemic temperature 28-30 °C) while allowing a complete arch and FET repair. Our approach, based on off-pump retrograde vascular stent graft deployment in distal arch/descending thoracic aorta, and the use of a retrograde endoballoon, allows the repair of extensive aortic pathologies during uninterrupted normothermic cerebral and lower body perfusion., Conclusions: The use of endoballoon occlusion has emerged in recent years as a safe and effective strategy to allow distal perfusion during FET repair. This technique minimizes or avoids the detrimental effects of hypothermia and systemic circulatory arrest and significantly reduces the operative times., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://cdt.amegroups.com/article/view/10.21037/cdt-22-73/coif).

Median sternotomy incision has shown to be a safe and efficacious approach in patients who require thoracic aortic interventions and still represents the gold-standard access. Nevertheless, over the last decade, less invasive techniques have gained wider clinical application in cardiac surgery becoming the first-choice approach to treat heart valve diseases, in experienced centers. The popularization of less invasive techniques coupled with an increased patient demand for less invasive therapies has motivated aortic surgeons to apply minimally invasive approaches to more challenging procedures, such as aortic root replacement and arch repair. However, technical demands and the paucity of available clinical data have still limited the widespread adoption of minimally invasive thoracic aortic interventions. This review aimed to assess and comment on the surgical techniques and the current evidence on mini thoracic aortic surgery., Supplementary Information: The online version contains supplementary material available at 10.1007/s12055-021-01258-2., Competing Interests: Conflict of interestThe authors declare no competing interests., (© The Author(s) 2021.)

Background: Although sutureless and rapid deployment aortic valve replacement (SURD-AVR) has been associated with an increased rate of permanent pacemaker (PPM) implantation compared to conventional AVR (c-AVR), the predictors of new conduction abnormalities remain to be clarified. This study aimed to identify risk factors for conduction disorders in patients undergoing AVR surgery., Methods: Data from 243 patients receiving minimally invasive AVR were prospectively collected. SURD-AVR was performed in 103 (42.4%) patients and c-AVR in 140 (57.6%). The primary endpoint was the occurrence of new-onset conduction disorders, defined as first degree atrioventricular (AV) block, advanced AV block requiring PPM implantation, left anterior fascicular block (LAFB), left bundle branch block (LBBB) and right bundle branch block (RBBB)., Results: The unadjusted comparison revealed that SURD-AVR was associated with a higher rate of advanced AV block requiring PPM when compared with c-AVR (10.5% vs. 2.1%, P=0.01). After adjusting for other measured covariates (OR: 1.6, P=0.58) and for the estimated propensity of SURD-AVR (OR: 5.1, P=0.1), no significant relationship between type of AVR and PPM implantation emerged. On multivariable analysis, preoperative first-degree AV block (OR: 6.9, P=0.04) and RBBB (OR: 6.9, P=0.03) were independent risk factors for PPM. Subgroup analysis of patients with normal preoperative conduction revealed similar incidence of PPM between SURD-AVR and c-AVR (1.3% vs. 1.9%, P=0.6). When compared with c-AVR, SURD-AVR was associated with a greater incidence of postoperative new onset LBBB (18.1% vs. 3.2%, P<0.001). This finding was confirmed after adjusting for the estimated propensity of SURD-AVR (OR: 6.3, P=0.009)., Conclusions: Our study revealed that the risk of PPM implantation in patients receiving surgical AVR is heavily influenced by the presence of pre-existing conduction disturbances rather than the type of valve prosthesis. Conversely, SURD-AVR emerged as an independent predictor for LBBB and was associated with an increased risk of PPM in patients presenting with RBBB., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2020 Annals of Cardiothoracic Surgery.

Staged replacement of the aortic arch and thoraco-abdominal aorta (TAA) with a frozen elephant trunk followed by TAA repair is a valuable treatment for patients with chronic TAA dissection. However, in patients with an unclampable descending thoracic aorta, the retrieval of the trunk can be problematic and the proximal stent graft-to-graft anastomosis technically challenging. Here we present our 'double layer' frozen elephant trunk technique to treat patients with TAA dissection., (© The Author(s) 2020.

Type Ia endoleak after thoracic endovascular aortic repair is an ominous complication that requires an aggressive treatment. Total arch replacement with a distal suture taking the native distal aorta, the stent graft, and the arch graft, by allowing a perfect closure of the proximal endoleak, represents the most common treatment in this setting. Nevertheless, such intervention continues to carry significant mortality and morbidity that are mostly related to prolonged extracorporeal circulation time and hypothermic circulatory arrest. Here, we present a technique for total arch replacement that, with the use of stent graft balloon endoclamping, avoids both hypothermia and circulatory arrest., (Copyright © 2020 The Society of Thoracic Surgeons.

Introduction: Type B aortic dissection (TBAD) is a threatening event that may lead to death for aortic rupture or multivisceral malperfusion in the acute phase and offers a poor prognosis for long term survivors. Thoracic endovascular aortic repair (TEVAR) has become the preferential therapy in acute and chronic complicated cases for its less invasivity compared to open surgery. However TEVAR is still encumbered by a significant number of reinterventions, caused by aortic neck aneurysmal degeneration, endoleaks and stent-graft induced new entry (SINE). This is even more true in patients with particularly fragile aortic wall like Marfan Syndrome (MS) in contrast to the excellent results of elective open surgery., Areas Covered: This review analyzes the current available TEVAR devices and techniques in TBAD and their technological advancements, especially those most suitable to TBAD anatomy, according to current literature., Expert Opinion: The continuous technological evolution of materials and device solutions ensures solid results of TEVAR in acute TBAD and may also potentially overcome some of the limitations of endovascular devices in this setting, paving the way for safer and more durable results and allowing for expanded indications in the future, even in the delicate population of collagenopathies, especially in MS.

Novel coronavirus disease-2019 (COVID-19) is an ominous infectious disease that seems capable to attack any organ system, leading in the most severe cases to patient death. COVID-19 has been associated with multiple cardiovascular complications of inflammatory and immune origin, leading to a wide spectrum of vascular damage, myocardial injury, stroke, and pulmonary obstruction. We report the case of a patient with COVID-19 infection who developed an acute aortic syndrome with the characteristics of aortic intramural hematoma., Competing Interests: The authors declare no conflict of interest related to this article., (The Author(s).

Objectives: The impact of minimally invasive extracorporeal circulation (MiECC) systems on the clinical outcomes of patients undergoing minimally invasive aortic valve replacement (MI-AVR) has still to be defined. This study compared in-hospital and 1 year outcomes of MI-AVR interventions using MiECC systems versus conventional extracorporeal circulation (c-ECC)., Methods: Data from 288 consecutive patients undergoing primary isolated MI-AVR using MiECC (n = 102) or c-ECC (n = 186) were prospectively collected. Treatment selection bias was addressed by the use of propensity score matching (MiECC vs c-ECC). After propensity score matching, 2 groups of 93 patients each were created., Results: Compared with c-ECC, MiECC was associated with a higher rate of autologous priming (82.4% vs 0%; P < 0.001) and a greater nadir haemoglobin (9.3 vs 8.7 g/dl; P = 0.021) level and haematocrit (27.9% vs 26.4%; P = 0.023). Patients who had MiECC were more likely to receive ultra-fast-track management (60.8% vs 26.9%; P < 0.001) and less likely to receive blood transfusions (32.7% vs 44%; P = 0.04). The in-hospital mortality rate was 1.1% in the MiECC group and 0% in the c-ECC group (P = 0.5). Those in the MiECC group had reduced rates of bleeding requiring revision (0% vs 5.3%; P = 0.031) and postoperative atrial fibrillation (AF) (30.1% vs 44.1%; P = 0.034). The 1-year survival rate was 96.8% and 97.5% for MiECC and c-ECC patients, respectively (P = 0.4)., Conclusions: MiECC systems were a safe and effective tool in patients who had MI-AVR. Compared with c-ECC, MiECC promotes ultra-fast-track management and provides better clinical outcomes as regards bleeding, blood transfusions and postoperative AF. Thus, by reducing surgical injury and promoting faster recovery, MiECC may further validate MI-AVR interventions., (© The Author(s) 2019.

Patients with severe aortic valve stenosis are currently treated with 2 different interventional techniques: surgical aortic valve replacement or transcatheter aortic valve implantation (TAVI). Both have strengths and limitations. On the one hand, TAVI represents a valuable option in high- and intermediate-risk patients and is commonly preferred over surgical aortic valve replacement in subjects with porcelain or severely calcified aorta, on the other, the lack of data on valve durability raises concerns on its use in young, low-risk patients. We present herein the case of a low-risk 71-year-old patient with a severely calcified ascending aorta. We successfully combined our minimally invasive surgical approach with the use of a percutaneous cerebral protection system commonly employed during TAVI procedures. We believe that cardiac surgeons could adopt transcatheter technology to improve operative results., (© The Author(s) 2019.

Bentall operation via median sternotomy has been largely shown to be safe and long-term efficacious and currently represents the "gold standard" intervention in patients presenting with aortic valve and root disease. However, over the last years, minimally invasive techniques have gained wider clinical application in cardiac surgery. In particular, minimally invasive aortic valve replacement through ministernotomy has shown excellent outcomes and becomes the first choice approach in numerous experienced centers. Based on these favorable results, ministernotomy approach has also been proposed for complex cardiac procedures such as aortic root replacement and arch surgery. Herein, we present our technique for minimally invasive Bentall operation using a ministernotomy approach., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© Indian Association of Cardiovascular-Thoracic Surgeons 2018.)

Aortic valve surgery has been undergone continuous development over the last years, involving less invasive techniques and the use of new technologies to reduce the traumatic impact of the intervention and extend the operability toward increasingly high-risk patients. Minimally invasive aortic valve replacement (AVR) has gradually been recognized as a less traumatic technique compared to median sternotomy, becoming first choice approach in numerous experienced centers. Herein we present our multidisciplinary minimally invasive approach for AVR, involving: (I) reduced chest incision; (II) rapid deployment AVR; (III) minimally invasive extracorporeal circulation system; and (IV) ultra fast track (UFT) anaesthetic management., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: The aim of this study was to determine perioperative factors influencing neurologic outcome in a single-center cohort of patients undergoing elective aortic arch operations., Methods: From January 2005 to June 2015, 791 consecutive patients received open aortic arch operations with either antegrade selective cerebral perfusion (ASCP) (636 patients [80.4%]) or deep hypothermic circulatory arrest (DHCA) (155 patients [19.6%]). Main indications were degenerative aneurysm (85%) and chronic postdissection aneurysm (9.1%)., Results: Hospital mortality (30 days) was 5.3%. Permanent neurologic dysfunction (PND) was observed in 42 patients (5.3%). Significant risk factors for PND appeared to be femoral artery cannulation (p = 0.003), progressive cardiopulmonary bypass (p = 0.001), circulatory arrest (p = 0.001), and ASCP time (p = 0.011). ASCP, in contrast to DHCA, was protective against PND (odds ratio [OR], 0.37; p = 0.003). Temporary neurologic dysfunction (TND) was observed in 49 patients (6.2%). Preoperative transient ischemic attack (TIA) (p = 0.001), progressive EuroSCORE (p = 0.001), left ventricular ejection fraction (LVEF) less than 50% (p = 0.003), and the use of femoral artery cannulation (p = 0.049) showed correlation in the univariate analysis. Stepwise logistic regression indicated TIA (p = 0.002; OR, 3.24) and the EuroSCORE (p = 0.003; OR, 1.23) as independent predictors of TND., Conclusions: Contemporary elective aortic arch repair can be achieved with low mortality and a low incidence of neurologic dysfunction. ASCP was confirmed to be the safest method of cerebral protection. The extent of aortic arch replacement (apart from the frozen elephant trunk [FET] procedure) was not related to increased rates of TND or PND., (Copyright © 2017 The Society of Thoracic Surgeons.

Background: This study assessed the early and long-term results of arch operations performed after a prior aortic operation., Methods: From 1994 to 2014, 154 consecutive patients (mean age, 59.7 years) underwent an aortic arch repair, after a previous aortic operation, at our institution. Antegrade selective cerebral perfusion was used in all cases. Chronic postdissection aortic aneurysm (87 [56.5%]) and degenerative aneurysm (43 [27.9%]) represented the most common indications for surgical intervention. A complete arch replacement was performed in 119 patients (77.3%), an associated root repair in 70 (45.5%), and the frozen elephant trunk technique was used in 55 (35.7%)., Results: Hospital mortality was 11.7% (n = 18). Postoperative permanent neurologic dysfunction occurred in 10 patients (6.4%). On multivariate analysis, cardiopulmonary bypass time (odds ratio, 1.02 per minute; p = 0.005) emerged as the only independent predictor of hospital death. Follow-up was 100% complete. The estimated survival at 1, 5, and 10 years was 79.6%, 69.9%, and 46.8%, respectively. Freedom from reoperation was 75.6% at 5 years and 54.6% at 10 years. Cox regression identified chronic postdissection aortic aneurysm (odds ratio, 4.2; p = 0.006) to be the only independent predictor of aortic reintervention. Late survival was comparable between degenerative aneurysm patients and the Italian population matched for age and sex (standardized mortality ratio, 1.9; p = 0.1). Longevity was reduced in patients operated on for chronic postdissection aortic aneurysm (standardized mortality ratio, 6.3; p < 0.001)., Conclusions: Arch operations after a previous open aortic repair can be performed with acceptable mortality and good long-term outcomes. Complete aortic resection did not increase hospital deaths and was associated with a low need for aortic reinterventions at follow-up., (Copyright © 2017 The Society of Thoracic Surgeons.

In adult the patent ductus arteriosus is a rare condition associated sometimes with lethal complications. We describe the case of a 44-year-old woman with a history of systemic lupus erythematosus admitted to our hospital with hoarseness and severe dyspnea. Clinical imaging examinations indicated a saccular aneurysm within a persistent ductus arteriosus with signs of impending rupture. Patient was not considered suitable for transcatheter closure and therefore she underwent open aortic repair. The procedure was uneventful and any significant complications occurred during postoperative course.

Objectives: Surgical management of the aortic root in type A acute aortic dissection (TAAAD) is controversial. This study compares short- and long-term outcomes of root replacement (RR) versus conservative root management (CR)., Methods: Between 1999 and 2014, 296 patients with TAAAD were treated in our department. The mean age was 63.7 years. Of the total, 69% were male. Ten patients (3%) presented with Marfan syndrome or bicuspid aortic valve. RR was performed in 119 (40%) patients, whereas CR in 177 (60%). Pre- and intraoperative data were stratified according to root management, and treatment bias was addressed by propensity-score (PS) analysis. Independent predictors of hospital and long-term mortality and proximal aortic reoperation were identified using multivariable logistic and Cox regression models., Results: Using PS analysis, we obtain two groups of 82 patients. The matched cohort hospital mortality rate was 21% in the CR group and 26% in the RR group (P = 0.45). The unadjusted comparison showed no statistical difference in early and long-term mortality between the groups. This result was confirmed after standard logistic regression and propensity-adjusted logistic regression. Freedom from proximal aortic reintervention was higher in the RR group (at 7 years RR: 96 ± 3% vs CR: 80 ± 6%, log-rank P = 0.02) and remained high in the matched cohort of patients (at 7 years RR: 98 ± 2 vs CR: 86 ± 6, log-rank P = 0.06)., Conclusions: Conservative and aggressive root management in acute aortic dissection provided similar results for early and late mortality. Nevertheless, a more extensive root intervention appeared to be protective against aortic reintervention., (© The Author 2016.

Objectives: To assess early and long-term outcomes in a large cohort of patients undergoing open aortic arch surgery., Methods: From 1996 to 2012, 623 consecutive patients (mean age: 62.8 years) underwent aortic arch interventions in our institution. Of these, 208 (33.4%) presented with an acute aortic syndrome (AAS) and 415 (66.6%) with a chronic aortic pathology (CAP). During the study period, our surgical strategy involved extensive resections of the diseased aortic tissue at elective interventions, and a tear-oriented aortic replacement in patients with acute dissection. More extensive interventions were often performed in younger patients, and in those with connective tissue diseases and bicuspid aortic valves. A total arch replacement was frequently performed (53.3%). Antegrade selective cerebral perfusion was used in all cases., Results: Overall in-hospital mortality was 23.1% in patients with AAS and 11.1% in patients with a CAP; in the same groups, postoperative permanent neurological dysfunction (PND) occurred in 9.6 and 5.6%, respectively. The follow-up was 94.4% complete. For in-hospital survivors, 5- and 10-year survival (%) were 79.4 ± 2.1 and 60.9 ± 3.2, respectively, not influenced by the underlying aortic disease. Cox regression identified age (hazard ratio [HR]: 1.048; P < 0.001), preoperative renal failure (HR: 2.3; P = 0.003), diabetes (HR: 1.805; P = 0.005) and PND (HR: 2.4; P = 0.03) to be independent predictors for the follow-up mortality. Overall, 109 (59% endovascular) aortic reinterventions were performed: 18.3% were proximal and 81.7% distal to the aortic arch. Five- and 10-year freedom from aortic redo (%) were 82.8 ± 1.9 and 77.7 ± 2.6, respectively. Aortic dissection (HR: 1.7; P = 0.03) was the only independent predictor of reoperative surgery at the follow-up., Conclusions: Aortic arch surgery was associated with satisfactory early and long-term outcomes. Survival was largely determined by patient comorbidities and postoperative PND. While the underlying aortic disease did not affect long-term mortality, chronic dissection was associated with increased need for aortic reinterventions., (© The Author 2014.
