Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients over 18
  • Patients with the ability to understand the study requirements, be able to given written informed consent, and be willing and able to comply with the study requirements (including follow-up visits).
  • Patient candidates to an aortic bioprosthesis implantation according to the standard clinical practice guidelines.
  • Patients requiring isolated aortic valve replacement, or in combination with coronary artery bypass surgery and / or in combination with ascending aorta replacement surgery.
  • Women are eligible for the study if: a) are not pregnant or breastfeeding, b) are not of childbearing potential, c) if women of childbearing potential, a negative urine pregnancy test should be done within 48 hours before the intervention and must use an effective contraceptive method.

You may not qualify if:

  • Cardiac surgery contraindications.
  • Patients who require other interventions than the isolated aortic valve replacement or with coronary artery bypass surgery and / or in combination with ascending aorta replacement surgery as concomitant procedure.
  • Patients with LVEF \< 30%.
  • Cardiac surgery reintervention.
  • Cardiogenic shock or hemodynamic instability within 24 hours prior to surgery.
  • Patient who are not willing to attend to the required follow-up visit.
  • Patient undergoing hemodialysis or with severe renal impairment (eGFR\<30ml/min/1,7m2).
  • Pregnant women.
  • Patients with hyperparathyroidism.
  • Life expectancy less than 2 years.
  • Patients with a history or diagnosis of a medical problem or psychiatric illness or disorder that, according to the investigator evaluation, would make the patient not eligible to participate in the study.
