NCT05912608

Brief 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.

Study Arms (2)

Conservative Type A Acute Aortic Dissection Repair (TAAAD-R)

ACTIVE COMPARATOR

All conservative TAAAD-R will be performed through a median sternotomy. The conservative TAAAD-R will include patients receiving valve-sparing root procedures and recipients of ascending aortic root sparing replacement if the intima separation extended into the sinuses resulting in commissural collapse.When necessary, the hemiarch technique will be used with a limited extension of the conservative procedure by resection of all the aortic tissue up to the left common carotid artery and which will be dictated according to the presentation of the lesion.

Procedure: Conservative TAAAD-RProcedure: Extensive TAAAD-R

Extensive Type A Acute Aortic Dissection Repair (TAAAD-R)

OTHER

All extensive TAAAD-R will be performed through a median sternotomy.The extensive TAAAD-R will include patients receiving replacement of the aortic root and total arch replacement procedures (TARP)

Procedure: Conservative TAAAD-RProcedure: Extensive TAAAD-R

Interventions

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.

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).
