Clinical Trial Summary

Acute type A aortic dissection (TAAD) persists as a clinicopathologic entity with high lethality in the current era. Several procedures are presently used to repair the TAAAD. The objective of this study is to analyze two groups of individuals using a conservative approach through root-sparing and hemiarch techniques in patients who are hospitalized in higher-risk clinical conditions or more aggressive procedures such as root replacement and total arch replacement in low-risk patients.

Description:

The target population enrolled in the registry includes patients with TAAAD.The high volume of patients that will be enrolled in this registry will receive proximal and distal aortic repair in elective, urgent or emergency clinical condition. Efforts of investigators will be concentrated in TAAAD repair using a conservative approach of root preservation and hemiarch reconstruction in the majority of patients who will be referred in critical clinical condition. High-risk patients with older age or more comorbidities had more conservative repairs to limit surgical insult to these complicated patients. Total arch reconstruction and root replacement will be optional procedures for specific subgroups of patients who may benefit from a more complex index finger operation without incurring additional immediate risk. Investigators hope to demonstrate a reduction in operative mortality and an improvement in early and late outcomes. The experience of investigators will be summarized in an algorithm for TAAAD repair with an analysis of early morbidity and mortality, as well as late survival and no reoperation.

Intervention

Procedure:
• Conservative TAAAD-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 TAAAD-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 hemiarch) or reimplantation of the innominate trunk only (partial hemiarch).
