We appreciate the authors' concerns about the quality of our work published the Journal of Thoracic and Cardiovascular Surgery. We totally agree with the two underlined points and we would like to simply answer the two questions.

It is true that prosthesis sizing is an important issue. All the reported patients had an aortic annulus diameter ranging from 20 to 23 mm. Smaller and larger annuli were considered as contraindicated so as to allow correct anchorage of the prosthesis in the annulus.

All the patients had the echographic aspect of a tricuspid aortic valve. We cannot answer Zegdi and colleagues because we do not have any experience with percutaneous aortic valve implantation in bicuspid valves. Bicuspid valves are generally more calcified than tricuspid valves and frequently come with a moderate dilatation of the aorta. They are less favourable for currently used percutaneous aortic valves.
