Clinical Trial Summary

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

Description:

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.

Intervention

Procedure:
• Conservative TAAD-R
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.
• Extensive TAAD- R
Patients who experienced dilatation of the sinuses of Valsalva >4.5 cm in diameter on computed tomography imaging, those with connective tissue disease, or those in whom intimal tears extended into the sinuses, will undergoing replacement of the aortic root using a biologic or mechanical composite valve graft or valve-sparing root reimplantation procedure.Total arch replacement procedures (TARP) will fulfilled with the use of deep hypothermic circulatory arrest and with either antegrade or retrograde cerebral perfusion, maintaining systemic cooling between 19°C to 25°C and depending on the surgeon's practice.TARPs will be carried out using 1- and 4-branch grafts and involved the resection of all the aortic tissue up to the left common carotid artery (total arch)
