Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling) is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

The pulmonary valves appeared to be more durable ( P value <0.001) and survival probabilities in small sized grafts were lower ( P value 0.008). One-, five-, and ten-year graft survival was 82, 76 and 73 %, respectively.
