A 58-year old man without Marfan syndrome was referred to our hospital for congestive heart failure due to severe mitral regurgitation. He had undergone sternal turnover with a rectus muscular pedicle for pectus excavatum 36 years previously. We were able to perform mitral valve repair via median sternotomy using a usual sternal retractor. There was no adhesion in the pericardium and the exposure of the mitral valve was excellent. We closed the chest in ordinary fashion without any problems in the fixation of the sternum or costal cartilage. There were no complications such as flail chest or respiratory failure.

A 62-year-old woman was admitted to a regional hospital for acute myocardial infarction. Emergency coronary angiography revealed occlusion of the first diagonal branch, and transesophageal echocardiography showed severe mitral regurgitation due to anterior papillary muscle rupture. She was transferred to our hospital in a state of cardiogenic shock despite the use of high-dose catecholamine and intra-aortic balloon pumping. We immediately performed mitral valve replacement. The patient's postoperative course was uneventful and she was ambulatory when transferred to another hospital on foot on postoperative day 19. Physicians should be aware that fatal anterior papillary muscle rupture may be caused by isolated occlusion of the diagonal branch.

A 14-year-old women who had a history of aortic root replacement at 7 years old admitted our hospital due to dilatation of aortic arch aneurysm. Loeys-Dietz syndrome was diagnosed when she was 10 years old. Computed tomography showed 70 mm proximal arch aneurysm. Operative findings revealed brachiocephalic artery and left common carotid artery branched from aneurysm. Partial arch replacement was performed and distal anastomosis was made between left common carotid artery and left subclavian artery. Close observation by CT regularly is necessary and undergo aortic repair not to miss the timing of surgery.

Purpose: Dental floss clip (DFC) traction-assisted endoscopic submucosal dissection (ESD) is widely performed owing to its simplicity. This study aimed to clarify the appropriate indications for the DFC traction method in early gastric cancer when ESD is performed by less-experienced endoscopists. Methods: and Methods: We retrospectively analyzed 1,014 consecutive patients who had undergone gastric ESD performed by less-experienced endoscopists between January 2015 and December 2020. Gastric ESD was performed without DFC in all cases before December 2017 [DFC (−) group, 376 cases], and ESD was performed with DFC in all cases after January 2018 [DFC (+) group, 436 cases]. The procedure time and rates of en bloc resection, complete resection, and adverse events of the groups were compared. Results: The procedure time did not differ significantly between the 2 groups. However, when comparing lesions >20 mm, the procedure time in the DFC (+) group was significantly shorter than that in the DFC (−) group (95±46 vs. 75±31, P<0.01). The procedure time for lesions located in the greater curvature of the upper or middle stomach and lesions >20 mm located in the lesser curvature side of the stomach in the DFC (+) group was significantly shorter than that in the DFC (−) group. Conclusions The indications for DFC during gastric ESD by less-experienced endoscopists include lesions located in the greater curvature of the upper or middle stomach, and lesions >20 mm located in the lesser curvature of the stomach.
