ABSTRACT
Objective: To introduce the construction idea and function for establishing China Cardiovascular Surgery Registry (CCSR)database and to provide a reference for domestic congener databases. Methods: Using peer database as reference, taking current status of cardiovascular surgery registry and hardware in our country with the necessity of international communication, we worked on a variables selection, metadata instruction, logic rules, case report form develpment and finally established a web-based, multi-functional database that enabled cross-database and international merging of data, forming a national intelligent data-exchanging platform for cardiovascular surgery. Results:CCSR database has over 300 variables of multiple topics including basic information, risk factors, medical procedures and endpoint events. Taking clinical and association data exchange standards as reference, it may conduct cross-discipline data connection, record important peri-operative information in relevant patients and meanwhile, it has the functions of automatic logic check, data report, statistical study, data export and importing the electronic medical records. Conclusion:CCSR database is a national platform accord with current status of Chinese cardiovascular surgery and characteristics, meanwhile it gives consideration to international communication and data exchange; which may play a important role in improving medical care and clinical investigation.

ABSTRACT
Objective: To preliminarily analyze the graft flow of right internal mammary artery (RIMA) in patients after coronary artery bypass grafting (CABG) using bilateral internal mammary artery (BIMA). Methods: A total of 52 patients received CABG by BIMA in our hospital from 2015-12 to 2016-07 were studied. The patients were younger than 65 years at the mean age of (56.6±6.8) years including 46 male. According to conduit grafting to left anterior descending artery (LAD), the patients were divided into 2 groups: RIMA anastomosed to LAD group, n=42 and LIMA anastomosed to LAD group, n=10. The immediate graft flow was measured by Veri Q system, surgical outcomes and graft flows were compared between 2 groups. Results: There were no operative death in all 52 patients, 1 had poor wound healing and received debridement and suturing, no one had operative complication in left 51 patients. The average LAD bridge flow in both groups were (28.7±11.5) ml/min and (31.8± 11.7) ml/min, the mean pulsation index (PI) were (2.3±0.7) and (2.0±0.4), P>0.05; the average RIMA graft flow were (28.7±11.5) ml/min and (21.1±11.0) ml/min, the mean PI were (2.3±0.7) and (2.6±1.1), P>0.05. Conclusion: Flows in RIMA-LAD graft and LIMA-LAD graft were similar; the flow of RIMA anastomosed to other target vessel was satisfactory which was an ideal graft for CABG.
