Quadricuspid aortic valve associated with aortic insufficiency.

Japanese Journal of Cardiovascular Surgery, 1989
33歳,男性,大動脈弁閉鎖不全.手術時,大動脈4尖弁であることが判明,右冠尖と左冠尖の間に過剰尖があり,この三つはほぼ同大,無冠尖が小さかった.Bjork-Shiley弁で置換,術後経過は良好である.大動脈4尖弁はまれで,報告は39例,大多数が成人になってから大動脈弁閉鎖不全となり,手術報告は9例である.最近,大動脈造影,心エコーにより診断可能となった.文献例の調査により,本症を過剰尖の位置により2群にわけることを提案した,I型は過剰尖が右冠尖と左冠尖の間,すなわち前方にあり,報告例はこれに属する.II型は過剰尖が右冠尖と無冠尖の間,すなわち後方にあり,この場合は全例,過剰尖が小さい.

A noncanonical role for Jagged1 in endothelial mechanotransduction

The FEBS Journal, EarlyView.
This study reveals a noncanonical role for Jagged1 in endothelial mechanotransduction. Shear stress modulates Jagged1 expression and subcellular localization. Loss of Jagged1 attenuates mechanotransduction and reduces Src, VEGFR2, and ERK signaling. Direct mechanical stimulation of Jagged1 induces activation of these signaling pathways.
