Acute Stanford type A aortic dissection (TAAD) is a life-threatening clinical status requiring surgery that is usually performed as a salvage procedure.We planned a multicenter study to evaluate the balance between the patient's condition and those therapeutic strategies that may limit the risk of late adverse events in patients who will be underwent surgery for appropriate management of TAAD
Substantial evidence has suggested a decrease of early mortality during the last years, however recently the Nordic Consortium for Acute Type A Aortic Dissection registry recorded 18% of 30-day mortality after surgery for ATAAD. Similarly, the prospective German Registry for Acute Aortic Dissection Type A confirmed this data reporting a 30-day mortality of 16.9%. Again, results from recent analysis of the Society of Thoracic Surgeon database that report 7353 procedures from 2014 and 2017 for acute TAAD revealed a 30-day mortality of 17%. Understanding the balance between the patient's conditions which may not allow extensive procedure and those treatment strategies which may limit the risk of late adverse events in patients who remain alive long after the surgery is essential for an appropriate management of ATAAD. The best treatment option in patients with ATAAD is dictated by the balance between patient conditions that may not allow for extensive procedures and those more conservative treatment strategies that limit the risk of late adverse events in patients who remain alive long after surgery. surgery. However, previous evidence from large series of patients do not provide information on the long-term durability of these procedures.
Here investigators planned a multicenter study to evaluate the contemporary early outcomes and duration of different surgical strategies for 15-year acute ATAAD in a large study population.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Conservative Type A Aortic Dissection Repair (TAAD-R) | The Conservative procedure will include patients receiving ascending aortic root sparing replacement with or without the implantation of the aortic hemiarch |
| |
| Extensive Type A Acute Aortic Dissection Repair (TAAD-R) | The extensive procedure will include patients receiving ascending aorta replacement associated to TARP |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Conservative TAAD-R | Procedure | Cardiac arrest will be ensured using antegrade potassium-rich cardioplegia solution delivered directly into the coronary ostium or after coronary sinus cannula insertion, in patients with aortic regurgitation aorta will be resected down to the sinotubular junction and the thrombus located in the false lumen of the aortic root will be removed so that the aortic lesion could be visualized. The commissures will be resuspended using 4-0 or 5-0 sutures reinforced with a Teflon pledget over each 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 revealing normal-sized aortic roots associated with poor-quality valve leaflets, concomitant aortic valve replacement with conventional xenograft or mechanical prosthesis will be preferred. |

| Rate of perioperative bleeding | Number of participants will receive postoprative transfused red blood cell units. The E-CABG ( coronary artery by pass grafting) classification of bleeding rate has been proposed as a simple classification of perioperative bleeding |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of urgent procedure | Number of participants who will require scheduled procedure within 24 hours of admission. | 30-days |
| Rate of emergency grade 1 | Number of participants will require procedure within 24 hours of hospital admission and who are symptomatic or minimally symptomatic with stable hemodynamic conditions and no signs of malperfusion. |

The retrospective multicenter study including patients who underwent surgery for acute TAAAD at 5 centers of cardiac surgery located in 2 European countries and Japan (2 France, 2 Italy and 1 Hokkaido ). Data will be prospectively collected fron patients (conservative vs estensive TAAD- R) treated during the study period and 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. Data on consecutive patients with acute TAAD will be collected with pre-specified baseline, operative and outcome variables.
