To the editor: We read the article by Côté et al with great interest.1 In their study, they examined the effect of oxidised low-density lipoprotein (ox-LDL) on the progression of aortic valve stenosis. They used a scoring system for remodelling and Doppler echocardiography pressure gradients of aortic valves of the patients at the time of valve surgery. The authors emphasised that an increased level of circulating ox-LDL is associated with worse fibrocalcific remodelling of valvular tissue in aortic stenosis, but there is a need for further studies to justify their results.

In our retrospective study,2 we evaluated the lipid profile and previous echocardiographic findings …
