Transcatheter aortic valve replacement: A journey of two decades and beyond

“…[5] However, TAVR volume shows geographical heterogeneity due to national economic resources and investment in novel medical services, ranging from over 0.3 per million to 200 per million people. [6] Although the adoption of TAVR in Chinese mainland relatively lagged behind that of the Western world, increasing momentum has been presented, particularly in recent years, with a total of 22,783 cases by October 2022.…”

Anatomical characteristics of patients with symptomatic severe aortic stenosis in China

“…[ 6 ] Some Chinese domestic devices have increased radial force of the stent frame to achieve optimal valve expansion in such settings. [ 7 ] Whether it may bring clinical benefits comparing with devices of higher conformability, along with a tailored treatment strategy and device design taking characteristics of Chinese patients into consideration, warrants further research studies. Balloon-expandable devices, on the other hand, provide greater opening force to secure circular expansion and minimize paravalvular leak but may be associated with higher risk of annular rupture.…”

“…The roughly twofold calcium burden in both bicuspid and tricuspid morphologies in China is also alarming since aortic root calcification has been identified as a risk factor for paravalvular leak, pacemaker implantation, and device success [6] . Some Chinese domestic devices have increased radial force of the stent frame to achieve optimal valve expansion in such settings [7] . Whether it may bring clinical benefits comparing with devices of higher conformability, along with a tailored treatment strategy and device design taking characteristics of Chinese patients into consideration, warrants further research studies.…”
