The modified Ross operation using a Dacron prosthetic vascular jacket does prevent pulmonary autograft dilatation at 4.5-year follow-up

Abstract

Provision of external support to the entire pulmonary autograft with a DVPJ prevents its dilatation following free-standing pulmonary autograft Ross operation when evaluated at the 4.5-year follow-up. The function and the geometry of the neo-aortic root are not affected negatively by this modification and the patients demonstrated normal exercise capacity.

Aortopathy associated with congenital heart disease: A current literature review

“…[ 57 ] In the more recent years the application of a Dacron tube for external support of the pulmonary autograft, to prevent sinus and sinotubular junction dilatation in freestanding roots, has gained renewed interest. [ 67 ] A combined ascending aortic replacement for aneurysm had no influence on late autograft function in a 5-year follow-up study, but the long-term fate of the neo-aortic valve in this setting is not known. [ 59 ]…”

Maladaptive aortic properties after the Norwood procedure: An angiographic analysis of the Pediatric Heart Network Single Ventricle Reconstruction Trial

“…27-29 The Ross procedure increasingly is being performed with reinforcement of the aortic root to prevent dilation and associated aortic insufficiency. 30,31 The Norwood operation differs from the Ross and arterial switch operations because the entire ascending aorta is reconstructed, and, as we demonstrate, dilation extends beyond the aortic root into the ascending and transverse arch.…”

A simplified technique for pulmonary autograft stabilization with the Valsalva prosthesis

“…Unlike pericardium, Dacron polyester fabric has no potential to contract or calcify with time. Al Rashidi and colleagues 3 have shown that reinforcement of the autograft prevents dilation as long as 4.5 years with a tube graft. We believe that the native shape of the neoaortic sinuses is preserved by the use of the Valsalva graft.…”
