Questionable Long-Term Results of the Extended Provisional Extension to Induce Complete Attachment (E-PETTICOAT) Technique in the Management of Chronic Type B Aortic Dissection.

Background: Published interim results of the extended provisional extension to induce complete attachment (e-PETTICOAT) technique suggested favorable remodeling in chronic type B Aortic Dissection (cTBAD). This report presents long-term results of the e-PETTICOAT technique for the management of cTBAD (without aneurysmal dilatation).
