An alternative technique for surgical repair of pulmonary dissection

Abstract

The other 2 patients had recurrence of mild regurgitation at the third and 30th months. Freedom from mitral regurgitation was 86.9%.

Successful beating‐heart repair of pulmonary artery dissection using a composite valve‐tube graft

“…While heart‐lung transplantation has been described for PAH patients with PA dissection, 7,8 psychosocial factors proved a significant barrier for our patient. Excision and replacement of the dissected PA aneurysm segment has also been reported, using a prosthetic graft, 9 homograft, 10 or stentless xenograft 11 . However, there is no consensus on which technique is preferred, or at what diameter PA aneurysms should be repaired.…”

“…Excision and replacement of the dissected PA aneurysm segment has also been reported, using a prosthetic graft, 9 homograft, 10 or stentless xenograft. 11 However, there is no consensus on which technique is preferred, or at what diameter PA aneurysms should be repaired. Previous reports reveal that RV failure is a significant potential complication after replacement of dissected PA aneurysms, requiring extracorporeal membrane oxygenation support or resulting in death in several cases.…”

Management of Giant Pulmonary Artery Aneurysm with Quadricuspid Valve Stenosis

“…20 The scientific literature contains several surgical techniques for pulmonary artery and valve replacements, like a full root homograft, a stentless xenograft root, a biological valved aortic conduit (Bioconduit), or a stented bioprosthesis sewn into a Dacron polyester tube graft. [21][22][23][24] In our patient, we decided to use a Bioconduit for the pulmonary root and valve replacement. Due to the large size of left pulmonary branch, it was impossible to resect the entire aneurysm and we built a conduit with bovine pericardial, sewn afterward on the Bioconduit.…”

Pulmonary Artery Dissection

“…When PAD is associated with pulmonary valve insufficiency, replacement of the pulmonary valve and artery may be necessary. Montesi et al described the implantation of a stentless valve in the pulmonary position and a Dacron tube in the pulmonary artery . Westaby et al used a bioprosthetic valve conduit …”
