  Purpose
The purpose of this study is to obtain data regarding the left ventricular mass (LVM) regression 6 months after the implant of an SJM Epic™ and SJM Epic™ Supra valve by comparing LVM regression measured with magnetic resonance imaging (MRI) to LVM regression measured with echocardiography (2-dimensional [2D] mandatory; 3-dimensional [3D] in sites where the technology is available).

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient requires, for the first time, isolated aortic valve replacement due to aortic stenosis or mixed aortic stenosis disease etiology when aortic stenosis is predominant and aortic regurgitation is mild.
  • Patient is of legal age in the host country.
  • Patient (or legal guardian) has signed a study specific informed consent form

Exclusion Criteria:

  • Patient was previously operated on with any heart surgery including heart valve replacement or coronary artery bypass graft (CABG); or underwent any form of myocardial revascularization in the past (including stents), etc.
  • Patient requires any concomitant heart surgery other than the isolated native aortic heart valve replacement and concomitant ascending aortic replacement (e.g not allowed are: multiple valve replacements or concomitant CABG, pacemaker insertions, or severe septal hypertrophy needing surgical excision, etc.)
  • Patient has unstable angina
  • Patient is in New York Heart Association functional class IV
  • Patient has significant abnormality in wall motion
  • Patient is affected by active endocarditis.
  • Patient has a cardiac pacemaker or automatic implanted cardiac defibrillator
  • Patient is affected by acute aortic dissection.
  • Patient is in chronic and persistent atrial fibrillation
  • Patient receives hemodialysis therapy
  • Patient has a medical condition which contraindicates implantation of the SJM Epic and Epic™ Supra Porcine Bioprosthetic Heart Valve (e.g. renal failure or abnormal calcium metabolism).
  • Patient has aneurysmal clips or carotid artery vascular stents
  • Patient has a neurostimulator
  • Patient has an implanted or external drug infusion device (e.g. insulin pump)
  • Patient has a bone growth/fusion stimulator
  • Patient has a cochlear, otologic, or ear implant
  • Patients with severe claustrophobia in which medical sedation is contraindicated or unable to resolve anxiety sufficiently
  • Patients with ocular foreign body (e.g. metal shavings)
  • Patient is pregnant or nursing
