Type A aortic dissection (TAAD) is a potentially life-threatening pathology associated with significant risk of mortality and morbidity. In acute forms of type A aortic dissection (TAAD) mortality is 50% by 24 h and 50% of patients die before reaching a specialist center. Rapid diagnosis and subsequent prompt surgical repair remain the primary goal for these patients.
In the last decade it has been observed that improvements in diagnostic techniques, initial management and increased clinical awareness have contributed to a substantial increase in the number of patients benefiting from a prompt diagnosis and undergoing surgery.However, survival after surgical repair has not yet reached optimal follow-ups and is burdened by high in-hospital mortality(16-18%)The main approach to acute type B non-complicated aortic dissection (TBAD) has always been to use medicines to control the patient's heart rate and blood pressure. However, recent findings suggest that a large number of patients treated for acute complicated (TBAAD) and non-complicated TBAD experience aortic complications, such as aneurysmal degeneration, at a later stage.
For patients requiring surgical repair for a TAAD, there is still some disagreement regarding which factors should be considered during the preoperative evaluation, the best decision-making process to undertake that best assesses procedural risk, and how operative mortality can be predicted. Furthermore, the impact of different surgical strategies on outcomes remains unclear.This prospective study was designed to evaluate the impact of the center volume-outcome relationship and that on mortality which remain poorly understood. A better understanding of the determinants of outcome in patients undergoing surgery could support decision making, aid in the design of service delivery, and improve outcomes for surviving patients who are referred to specialized centers for treatment of aortic disease.Furthermore, the study aims to evaluate whether precise risk stratification can provide better patient counseling and be used for unit-surgeon benchmarking. Ultimately in the present study, we aimed to investigate outcome predictors in patients undergoing surgery for TAAD, including clinical and perioperative variables as well as to evaluate follow up beyond 15 years.TBAD occurring beyond the left subclavian artery (LSA) is classified in chronological order based on the timing of clinical presentation: acute (14 days or less), subacute (more than 14 days and less than or equal to 3 months), and chronic (more than 3 months).TBADs are also divided into complicated or non-complicated based on their initial clinical manifestation. Acute complicated TBAD is characterised by tearing of the aorta, pain, rapid expansion, hypertension, or blockages in the vasculature.Malperfusion syndrome is the most common complication, occurring in nearly 30% of cases. More than 30% of patients with mesenteric compromise following aortic dissection die .

| Conservative Root- Sparing Aortic Valve Resuspension with or without Hemiarch Repair | Procedure | Cardiac arrest will be performed by administering a potassium-rich antegrade cardioplegia solution delivered directly into the coronary ostium or in the case of aortic regurgitation after insertion of the coronary sinus cannula.The aorta will be resected up to the sinotubular junction and the thrombus located in the false lumen of the aortic root will be removed so that the aortic lesion can be visualized. The commissures will be resuspended using 4-0 or 5-0 sutures reinforced with a Teflon pledget above every commissure. A 4-0 or 5-0 polypropylene suture will be chosen to seal the proximal anastomosis and this suture line will also be used to secure the intima to the adventitia. In patients demonstrating normal-sized aortic roots associated with poor-quality valve leaflets, concomitant aortic valve replacement with conventional xenograft or mechanical prosthesis will be preferable. |

The STAAD study is a prospective multicenter registry including patients who will underwent surgery for acute TAAD at 6 centers of cardiac surgery located in 2 European countries and Japan (3 France, 2 Italy and 1 Hokkaido ). Data will be prospectively collected from patients (conservative vs estensive Type A aortic dissection repair) who will be treated during the study period. In addition, the aim will be to gather further data for future clinical research on this topic. Preoperative and postoperative variables will be included during in-hospital stay and follow-up data instead they will be included on subsequent encounters for all other patients who will be hospitalized.
