Figure 1 Top: Image of the Perceval sutureless valve (courtesy of LivaNova, Milan, Italy) and the width from the eyelet to the sealing collar edge (insert, between arrows). Middle: Transesophageal echocardiographic image showing the distance from the annulus to the lower edge of the sealing collar (between arrows): 4 mm in a patient without PPM (left) and 10 mm in a patient with PPM for heart block (right). Bottom: Distance from annulus to lower edge of sealing collar for all patients.
