A 45-year-old woman with an 8-year history of systemic lupus erythematosus (SLE) was admitted with complaints of sudden onset of chest and back pain and syncopal attack. Aortography showed DeBakey type I acute aortic dissection. She has been maintained on a small dose of corticosteroids (prednisone 5mg/day). After antihypertensive drug treatment, a replacement of the total aortic arch and arch vessels was successfully performed. The postoperative course was uneventful and she has had no relapse of SLE.

We herein review the early results of minimally invasive coronary artery bypass (MIDCAB). From April 1994 to November 1998, 23 patients underwent MIDCAB, and 12 patients underwent coronary artery bypass grafting with cardiopulmonary bypass (CABG). We compared and analyzed the findings of these two groups. Regarding preoperative factors, the MIDCAB group included elderly patients, while the CABG group consisted of younger patients. However, the frequency of hemodialysis, respiratory disorders and cerebral vascular accidents did not differ significantly between the 2 groups. Regarding perioperative factors, the MIDCAB group needed a shorter operation time, and also had a lower bleeding volume, and a low incidence of blood transfusion. Regarding the postoperative course, the MIDCAB group needed a shorter artificial respiration time, and a shorter postoperative hospital stay, and no mortality was observed. The graft patency of the MIDCAB group was lower (88%) than the CABG group (100%). However, the graft patency of the MIDCAB group reached 94% after we used a stabilizer in the operation. In conclusion, the operation results of the MIDCAB group were comparatively better than those of the CABG group. Thanks to recent technological advances, the results of MIDCAB continue to improve. Though MIDCAB remains an invaluable operative modality for the treatment of one-vessel disease, surgeons must be careful to select appropriate candidates for this operative method.

A 47-year-old man was admitted with symptoms of angina pectoris. After evaluating the patient, coronary artery bypass grafting (CABG) was performed. First, the left internal thoracic artery (LITA) was grafted to the obtuse marginal branch (OM), and then the right gastroepiploic artery (RGEA) was grafted to the posterior descending branch (PD). Just after completing anastomosis, we performed intraoperative thermal coronary angiography. The RGEA-PD was patent. However, the LITA-OM was not patent on thermal coronary angiography. After a re-anastomosis was done at the LITA-OM, thermal coronary angiography was again performed and the LITA-OM was found to be patent. The postoperative course was uneventful, and all grafts were patent on postoperative angiography. In conclusion, intraoperative thermal coronary angiography was found to be useful for CABG.

The JCVSD (Japan Cardiovascular Surgery Database) was organized in 2000 to improve the quality of cardiovascular surgery in Japan. Web-based data harvesting on adult cardiac surgery was started (Japan Adult Cardiovascular Surgery Database, JACVSD) in 2001, and on congenital heart surgery (Japan Congenital Cardiovascular Surgery Database, JCCVSD) in 2008. Both databases grew to become national databases by the end of 2013. This was influenced by the success of the Society for Thoracic Surgeons' National Database, which contains comparable input items. In 2011, the Japanese Board of Cardiovascular Surgery announced that the JACVSD and JCCVSD data are to be used for board certification, which improved the quality of the first paperless and web-based board certification review undertaken in 2013. These changes led to a further step. In 2011, the National Clinical Database (NCD) was organized to investigate the feasibility of clinical databases in other medical fields, especially surgery. In the NCD, the board certification system of the Japan Surgical Society, the basic association of surgery was set as the first level in the hierarchy of specialties, and nine associations and six board certification systems were set at the second level as subspecialties. The NCD grew rapidly, and now covers 95% of total surgical procedures. The participating associations will release or have released risk models, and studies that use 'big data' from these databases have been published. The national databases have contributed to evidence-based medicine, to the accountability of medical professionals, and to quality assessment and quality improvement of surgery in Japan.
