Autograft remodeling after the Ross procedure by cardiovascular magnetic resonance imaging: Aortic stenosis versus insufficiency.

The Journal of thoracic and cardiovascular surgery

Lenoir M, Emmott A, Bouhout I, Poirier N, Tousch M, El-Hamamsy I, Mongeon FP.
PMID: 32739166
J Thorac Cardiovasc Surg. 2020 Jun 27; doi: 10.1016/j.jtcvs.2020.03.185. Epub 2020 Jun 27.

BACKGROUND: Studies suggest that patients undergoing the Ross procedure for aortic insufficiency are at greater risk of autograft dilatation than those with aortic stenosis. By using a tailored Ross technique to mitigate autograft dilatation in patients with aortic insufficiency,...

Structural abnormalities after aortic root replacement with stentless xenograft.

The Journal of thoracic and cardiovascular surgery

Dagnegård HSH, Sigvardsen PE, Ihlemann N, Kofoed KF, El-Hamamsy I, Bekke K, Valentin JB, Lefebvre L, Johnsen SP, Søndergaard L, Lund JT, Smerup MH.

OBJECTIVE: In complex and high-risk aortic root disease, the porcine Freestyle stentless bioprosthesis (Medtronic Inc, Minneapolis, Minn) is an important surgical treatment option. We aimed to determine prevalence and clinical effect of structural and functional abnormalities after full-root Freestyle...

The Ross procedure and valve-sparing root replacement procedures in the adult patient: do guidelines follow the evidence?.

Annals of cardiothoracic surgery

Vervoort D, El-Hamamsy I, Chu MWA, Peterson MD, Ouzounian M.
PMID: 34422555
Ann Cardiothorac Surg. 2021 Jul;10(4):433-443. doi: 10.21037/acs-2021-rp-24.

Prosthetic aortic valve replacements have long been the mainstay of valvular surgery due to their favorable outcomes and low operative complexity. Yet, mechanical valves require lifelong anticoagulation, whereas bioprosthetic valves increase the risk for earlier and more frequent reoperation....
