In order to extend the volume of participating sites, and build a representative database for the performance, in-hospital as well as 1-year outcomes of CABG and/or valve surgery in large cardiac surgery centers in China, at the year of 2013, China National Center for Cardiovascular Diseases (NCCD) and Fuwai Hospital leveraged The China Cardiovascular Surgery Registry (CCSR) network to push the CCSR Study forward. The CCSR Study established a network of 90 participating sites with cardiovascular surgery volume > 100 per year, and capability of performing CABG and/or valve surgery. The participating sites are required to consecutively and routinely submit CABG and valve surgery data regarding patients' personal information, risk factors, surgery performance, in-hospital outcomes and prescription drugs, through a web-based and paperless data collection system. The investigators also encourage all sites to interview patients at 1-month and 1-year after index procedure for mid-term outcomes and medications after discharge. The investigators conduct routine remote and on-site monitoring and auditing to ensure integrity and accuracy of data. Ethics Committee of Fuwai Hospital approved the study design and audits the conducting yearly.
