  1. Percutaneous Aortic Valve Replacement without Predilatation for Symptomatic Severe Aortic Stenosis in High-Risk Patients Lev G, Valdivieso L, Fava C, Caponi G, Hidalgo G, Mendiz O. Favaloro Foundation University Hospital. Buenos Aires. Argentina.

  2. Since the beginning of percutaneous Aortic valve replacement was considered that the previous balloon valvuloplasty was essential to facilitate optimal implant and expansion. CoreValve PrimarioBackground

  3. The procedure has a certain risk of stroke and valvuloplasty may have an important responsibility. The rapid pacing for valvuloplasty can have deleterious effect mainly the pts with ventricular dysfunction. CoreValve PrimarioBackground

  4. Primary Aortic Valve ReplacementAIM To assess the in-hospital and follow-up results of the primary (without predilatation) percutaneous aortic valve replacement with the selfexpandable Nitinol CoreValve device (Medtronic®), in patients with symptomatic aortic valve severe stenosis and high surgery risk.

  5. Primary Aortic Valve ReplacementMaterials and Methods • Between march 2009 and december 2011, 57 consecutive patients (ptes) with symtomatic severe aortic valve stenosis were treated with CoreValve device. • 48 ptes (84%) with primary elective implantation.

  9. Primary Aortic Valve ReplacementResults • CoreValve´s primary implantation was succesfully achieved in 48 ptes: • Predilatation was requiered in 1 patient because of extremely asymetric valve expansion. • Postdilatation was necessary in 15 ptes (31%).

  12. Primary Aortic Valve ReplacementConclusión The percutaneous aortic valve replacement without predilatation with the self expandable Nitinol device was safe and efective with low Stroke incidence.
