text: ≥80 years.2 Because of the high prevalence of this rhythm disorder in the elderly population as well as similar risk factors for AF and severe degenerative aortic stenosis, both conditions may coexist in ≤50% of patients.3,4 AF importantly affects cardiovascular physiology attributable to loss of atrioventricular synchrony and irregularity of ventricular contraction resulting in reduced cardiac output and increased filling pressures,5 which may be further accentuated in the presence of severe aortic stenosis and myocardial hypertrophy.
