NCT03280433

Brief Summary

This translational study was designed to explore the association of the quantity and quality of epicardial adipose tissue (EAT) with coronary artery disease (CAD), left atrial remodeling and postoperative atrial fibrillation in a high cardiovascular disease-risk population. The investigators expect to identify new biochemical factors and biomarkers in the crosstalk between the epicardial adipocytes, coronary plaques and atrial cardiomyocytes that are involved in the pathogenesis of atherosclerosis and atrial fibrillation, respectively.

Outcome Measures

Primary Outcomes (4)

  • New onset atrial fibrillation

    Incidence of atrial fibrillation after aortic valve replacement

    Intra-hospital (i.e. from surgery until hospital discharge which means 7 days on average)

  • Left atrial remodelling by transthoracic echocardiography and magnetic resonance imaging

    Change in left atrial strain and volumes

    6-month following aortic valve replacement

  • Frailty syndrome according to Fried et al. scale

    Change in frailty syndrome classification

    6-month following aortic valve replacement

  • Coronary artery disease according to the presence of coronary stenosis and/or calcification

    Prevalent coronary artery stenosis and coronary calcification

    Baseline

Secondary Outcomes (2)

  • Left ventricular hypertrophy by transthoracic echocardiography and magnetic resonance imaging

    6-month following aortic valve replacement

  • Right ventricular structure and function by transthoracic echocardiography and magnetic resonance imaging

    6-month following aortic valve replacement

Other Outcomes (1)

  • Mortality

    3- to 5-year after aortic valve replacement

Sampling MethodProbability Sample
Study Population

Symptomatic severe aortic stenosis referred to aortic valve replacement.

You may qualify if:

  • symptomatic severe aortic stenosis patients (defined as aortic valve area of \< 1 cm2 or 0.6 cm2/m2 by transthoracic echocardiography) referred to aortic valve replacement.

You may not qualify if:

  • diagnosis of acute coronary syndrome in the last 3 months.
  • prior history of persistent or permanent atrial or flutter fibrillation.
  • coexisting moderate to severe aortic valve regurgitation or moderate to severe mitral valve disease, bicuspid aortic valve.
  • left ventricular dilatation \[end-diastolic volume index \>75 mL/m²\].
  • left ventricular ejection fraction \<55%.
  • chronic renal failure stage 3 to 5 defined as glomerular filtration rate GFR estimated by Cockcroft-Gault formula adjusted for body surface area \< 30 mL/min/1.73m².
  • moderate to severe chronic obstructive pulmonary disease defined as forced expiratory volume in one second \<50% according to the 2011 Global Initiative for Chronic Obstructive Pulmonary Disease guidelines.
  • active malignancy (i.e. With no evidence of recurrence and no longer receiving active treatment).
