Japanese Cardiovascular Surgery Database as a National Clinical Database
The JCVSD is a nationwide registry of patients undergoing cardiovascular surgery in Japan that was described previously.2 Data collection is conducted using the National Clinical Database platform; information is linked to cardiovascular surgery certification with participating cardiac surgical units surveyed every year to ensure the exact dominance of cases against actual overall surgical cases performed across the country. Data from 580 cardiac surgery units located throughout Japan (nearly
Results
We identified 41,567 patients undergoing isolated OPCAB during the study period in JCVSD. After excluding those who did not meet inclusion criteria (25,131), we enrolled 6890 and 9546 patients undergoing OPCAB using no-touch or a device, respectively, and then identified 5012 matching patients for each group.
Comment
Numerous reports and discussions have addressed the impact of various types of ascending aortic manipulation during CABG for perioperative complications, especially the incidence of stroke.2,8, 9, 10, 11, 12, 13, 14, 15 In beginning our review of results other than neurological events, we found that the longer operation time in the device group may have resulted from proximal anastomosis requiring additional manipulation compared with the no-touch group, whereas the more frequent use of
