  1. Partial aortic root remodeling with selective replacement of the non-coronary sinus: does aortic valve morphology influence outcomes? Botta L, Cannata A, Bruschi G, Trunfio S, Merlanti B, Russo CF, Taglieri C, Martinelli L.

  2. These aneurysms begin in the ascending aorta and extend into the root and arch. The pattern of root dilation is determined by pressure and flow characteristics. The sinotubular junction (STJ) enlarges first followed by the noncoronary and right coronary sinuses. Though the annulus remains stable, the respective valve cusps are retracted and splayed producing central aortic regurgitation. The left coronary sinus usually retains normal dimensions until a very advanced stage, except in patients with sitis inversus where the left sinus dilates first.

  9. CONCLUSIONS When dilatation of the aortic root is confined to the Non-coronary sinus of Valsalva, the selective replacement of this sinus may represent a good compromise, with excellent early and midterm outcomes. In patients with a bicuspid aortic valve, risk of aortic related adverse events is rare and similar to that of patients with a tricuspid valve. More patients and a longer follow-up is mandatory to confirm these preliminary results.
