Background: The current study aims to report the presentation of the malperfusion syndrome in patients with acute type A aortic dissection admitted to surgery and its impact on mortality., Methods: Data were retrieved from the multicenter European Registry of Type A Aortic Dissection. The Penn classification was used to categorize malperfusion syndromes. A machine-learning algorithm was applied to assess the multivariate interaction's importance regarding in-hospital mortality., Results: A total of 3902 consecutive patients underwent repair for acute type A aortic dissection. Local malperfusion syndrome occurred in 1584 (40.59%) patients. Multiorgan involvement occurred in 582 patients (36.74%) whereas 1002 patients (63.26%) had single-organ malperfusion. The prevalence was the greatest for cerebral (21.27%) followed by peripheral (13.94%), myocardial (9.7%), renal (9.33%), mesenteric (4.15%), and spinal malperfusion (2.10%). Multiorgan involvement predominantly occurred in organs perfused by the downstream aorta. Malperfusion significantly increased the risk of mortality (P < .001; odds ratio, 1.94 ± 0.29). The Boruta machine-learning algorithm identified the Penn classification as significantly associated with in-hospital mortality (P < .0001, variable importance = 7.91); however, 8 other variables yielded greater prediction importance. According to the Penn classification, mortality rates were 12.38% for Penn A, 20.71% for Penn B, 28.90% for Penn C, and 31.84% for Penn BC, respectively., Conclusions: Nearly one half of the examined cohort presented with signs of malperfusion syndrome predominantly attributable to local involvement. More than one third of patients with local malperfusion syndrome had a multivessel involvement. Furthermore, different levels of Penn classification can be used only as a first tool for preliminary stratification of early mortality risk., Competing Interests: Conflict of Interest Statement E.Q. receives payment or honoraria from Cardiva SL, AtriCure, Medtronic, and Edwards.

Background: Extended aortic repair is considered a key issue for the long-term durability of surgery for DeBakey type 1 aortic dissection. The risk of aortic degeneration may be higher in young patients due to their long life expectancy. The early outcome and durability of aortic surgery in these patients were investigated in the present study., Methods: The subjects of the present analysis were patients under 60 years old who underwent surgical repair for acute DeBakey type 1 aortic dissection at 18 cardiac surgery centres across Europe between 2005 and 2021. Patients underwent ascending aortic repair or total aortic arch repair using the conventional technique or the frozen elephant trunk technique. The primary outcome was 5-year cumulative incidence of reoperation on the distal aorta., Results: Overall, 915 patients underwent surgical ascending aortic repair and 284 patients underwent surgical total aortic arch repair. The frozen elephant trunk procedure was performed in 128 patients. Among 245 propensity score-matched pairs, total aortic arch repair did not decrease the rate of distal aortic reoperation compared to ascending aortic repair (5-year cumulative incidence, 6.7% versus 6.7%, subdistributional hazard ratio 1.127, 95% c.i. 0.523 to 2.427). Total aortic arch repair increased the incidence of postoperative stroke/global brain ischaemia (25.7% versus 18.4%, P = 0.050) and dialysis (19.6% versus 12.7%, P = 0.003). Five-year mortality was comparable after ascending aortic repair and total aortic arch repair (22.8% versus 27.3%, P = 0.172)., Conclusions: In patients under 60 years old with DeBakey type 1 aortic dissection, total aortic arch replacement compared with ascending aortic repair did not reduce the incidence of distal aortic operations at 5 years. When feasible, ascending aortic repair for DeBakey type 1 aortic dissection is associated with satisfactory early and mid-term outcomes., Trial Registration: ClinicalTrials.gov Identifier: NCT04831073., (© The Author(s) 2024.

The treatment of complex multi-segment disease concomitantly affecting the aortic arch and descending thoracic aorta is technically challenging. Until the 1990s, such extensive pathology was addressed by median sternotomy for aortic arch replacement followed by a traumatic thoraco-abdominal incision for reconstruction of the descending aorta as a single- or two-stage procedure. The advent of the conventional elephant trunk procedure by Borst in 1983 simplified the second-stage of this procedure by eliminating the need for clamping of the descending thoracic aorta. However, graft-related complications and the considerable inter-stage mortality were significant limitations associated with the conventional elephant trunk procedure. The emergence of endovascular technology and availability of dedicated arch prostheses culminated in a major paradigm change with the introduction of the frozen elephant trunk (FET) concept by Kato and colleagues in the mid-1990s. This one-stage procedure permits concurrent total aortic arch replacement with antegrade delivery of a descending aortic stent-graft which itself functions as a proximal landing zone to facilitate prospective endovascular intervention to treat residual or de novo disease in the more distal aorta. The frozen elephant technique has been applied extensively in acute aortic dissection to restore true lumen patency, occlude descending aortic intimal tears and promote false lumen thrombosis, as well as for chronic degenerative arch aneurysms. The Thoraflex Hybrid and E-vita Open are the two most common commercially available hybrid FET prostheses. This review aims to discuss the development, indications, surgical technique, currently available prostheses, clinical outcomes and future directions regarding the FET procedure., 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-22-330/coif).

Patients with a bicuspid aortic valve (BAV) are at increased risk of valvular regurgitation compared to their counterparts with a tri-leaflet aortic valve. There is now increasing emphasis to offer BAV repair to mitigate the risks of prosthesis-related complications, including thromboembolism, hemorrhage and endocarditis, as well as structural valve deterioration and future reoperation with conventional valve replacement, particularly in younger populations. Furthermore, over the preceding two decades, our greater understanding of the functional anatomy of the BAV, pathophysiological mechanisms of BAV insufficiency, and the development of a functional classification of aortic regurgitation have significantly contributed to the evolution of aortic valve reconstructive surgery. In this commentary, we discuss a recent article from the Journal of Cardiac Surgery comparing external annuloplasty and subcommissural annuloplasty as techniques for BAV repair., (© 2021 Wiley Periodicals LLC.)

Background: Oesophageal carcinoma (EC) is the eighth most common cancer. Surgery is the cornerstone of management for resectable EC. Trans-thoracic oesophagectomy (TTE) and trans-hiatal oesophagectomy (THE) are the two most widely practised procedures. Most of the related controversies are centred on both early and late post-operative complications and mortality (in terms of overall survival and cancer-free survival).This was a single-centre, retrospective, comparative study analysing the outcomes of two EC resection methods. All 87 patients underwent surgery by the same surgical team over 13 years. Consequently, 87 oesophagectomies with curative intent were performed and divided into the TTE group (group A = 47) and the THE group (group B = 40)., Results: The mean patient age was 65.60 ± 6.30 years in the TTE group and 63.48 ± 9.34 years in the THE group. No significant difference was found in operative time, blood loss or duration of stay in the intensive care unit. The duration of hospital stay was significantly different between the THE and TTE groups (17.25 ± 5.92 vs. 12.93 ± 3.44, respectively; P ≤ 0.001). In-hospital mortality was higher in the TTE group (9/47, 19.14%) than in the THE group (5/40, 12.5%) ( P = 0.400). The mean survival rate from our series showed the superiority of group A (TTE) (65.56 months) over group B (THE) (45.01 months), with P = 0.146., Conclusion: No high level of evidence suggests the superiority of one surgical procedure over another. The THE procedure is less time-consuming concerning care and follow-up, and most patients were more satisfied and experienced less pain than with the TTE procedure. Both THE and TTE have comparable post-operative anastomotic complications, and they have no significant long-term survival differences., Competing Interests: Competing interestsNo conflict of interest associated with this draft, (© The Author(s) 2020.)

Foreign body aspiration (FBA) is a common and lethal accident in the pediatric age group. It requires early recognition and treatment by rigid bronchoscopy to avoid fatal outcomes. Objective. The aim of this study was to study the pattern of FBA in the tracheobronchial tree as well as the success rate of rigid bronchoscopy in children admitted to a single center and to analyze the relationship of the type of foreign body (FB) with patients' age, presentation, and complications. Methods. A retrospective cross-sectional study of FBA was conducted in children in the Sulaimani/Kurdistan region, Iraq, admitted to the emergency teaching hospital of the University of Sulaimani from January 2014 to March 2016. Result. Data of 83 patients between 6 months and 15 years old were studied. The most affected was the 1- to 5-year-old group. There was a slight female predominance (male to female ratio 0.93:1). The most common FB was sunflower seed (49.4%). History of choking was present in 92.8% of patients; 55.4% had normal air entry, and 37.3% had no added sound on chest auscultation. Normal chest X-ray (CXR) was found in 40% of patients. The most common site was the right bronchial tree (39.8%). Two patients needed mechanical ventilation; both of them died. There was a significant relationship between the type of FB ( P = .013, .000, respectively). Conclusion. Medical history is the most important factor for reaching the diagnosis; bronchoscopy is mandatory if choking was witnessed, even if examination and CXR are normal. Organic material causes more local reaction than nonorganic material., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
