Left Atrial Volume Index in Asymptomatic Aortic Stenosis

Aortic stenosis results in increased filling pressures of the heart. Size and function of the left atrium may be a marker for more advanced heart disease (heart failure) in patients with severe aortic stenosis, not presenting any apparent symptoms. The goal of this study is to establish the importance and possible implications of left atrial dilation in asymptomatic patients with aortic valve stenosis.
