<International Circulation>:Are there any new techniques emerging in the field of interventional cardiology?

Prof. Marco: The treatment of valvular disease by a percutaneous approach is very fascinating. We are now using a percutaneous approach to implant aortic valve prostheses. In China， there may be a future for this treatment. Also， the treatment of mitral regurgitation by a transcatheter approach is emerging and this may be a great opportunity for China. In the field of coronary intervention there is a new generation of DES that is emerging in the U.S， Europe， and China that have a great future for the treatment of patients with coronary artery disease. Bioabsorbable technology may be the future because this eliminates metal in the coronary artery.
