Abstract : Aneurysms of the Sinus of Valsalva (ASOV) are rare. We describe two cases of huge unruptured ASOV and discuss the management options. The first case was treated with sinus reconstruction and the second case was treated with "Hemiroot Replacement". One year follow up was uneventful. Although unruptured, hemodynamically significant ASOV should be treated surgically to avoid long term complications.
