Gelweave Valsalva™

Gelweave ValsalvaGelweave Valsalva™

Gelweave Valsalva™, the world’s first aortic root graft. It is used in valve sparing or combined prosthetic valve implant procedures.

Product Details

Gelweave Valsalva™ is the world's first custom designed aortic root graft that is indicated for repair and replacement of damaged and diseased thoracic aorta in cases of aneurysm, dissection or coarctation. It is used in valve sparing or combined prosthetic valve implant techniques.

Gelweave Valsalva

Gelweave Valsalva™ consists of 3 sections, a body, skirt and collar. This unique design,

  • Closely matches the aortic root anatomy16
  • Mimics the natural response of the sinuses of Valsalva™16
  • Reduces the tension on the coronary anastomoses17
  • Has the potential to increase the lifespan of the natural valve18

Studies have shown that Gelweave Valsalva™,

  • Exhibits superior aortic valve leaflet opening and closing compared to standard tube grafts, more similar to healthy individuals16,18
  • Due to the presence of the pseudosinuses, created by the “skirt” and the well defined sinotubular junction, facilitates near normal valve leaflet motion with the potential for prolonged valve leaflet longevity18,19
  • May decrease the incidence of  postoperative complications such as bleeding or late pseudoaneurysm formation17

FAQs

FAQs

1. Can Gelweave™ be used without a cautery?

All woven grafts are prone to fraying when cut with scissors and this may lead to reduced suture retention. Cauteries are used as an alternative minimising the degree of fraying and allowing the graft to be shaped for specific patient needs.

Note: Immersion of the Gelweave prosthesis in saline immediately prior to use will prevent focal burning, which may result during cauterisation. Grafts should be immersed in saline for no longer than 5 minutes. This is not required if already rinsed in Rifampicin and/or Heparin.
