A 78-year-old man presented with back pain 20 years after aortic root replacement using a homograft and was admitted with a diagnosis of pyogenic spondylitis. The patient had a history of prosthetic valve infective endocarditis (PVE) 9 months after aortic valve replacement (AVR) at 57 years of age at another hospital, and had undergone aortic root replacement using a homograft. Streptococcus anginosus was detected in blood culture, and antibiotic therapy was commenced according to the treatment of PVE. During the course of the treatment, the diagnosis of PVE was confirmed due to worsening aortic regurgitation (AR) and a finding of suspected vegetation attachment to the right coronary cusp. Since there were no embolic symptoms or heart failure, antibiotic therapy was preceded by surgery on the 33rd day. Intraoperatively, the homograft showed a highly calcified sinus of Valsalva and each valve leaflet was very fragile. The aortic valve had a vegetation adherent to the tip of the right coronary leaflet, but the infection was localized and did not extend to the annulus. Although aortic root replacement had been considered, the patient was elderly and had impaired activities of daily living, so AVR was performed in order to reduce the invasiveness of the procedure. The annulus was so hard that the needle could not be passed through. It was possible to thread the annulus by inserting the needle through the autologous tissue below the suture line on the proximal side of the homograft at the previous surgery. A bovine pericardial patch was used to close the aortotomy line of sclerotic homograft. There was no recurrence of infection, and the patient was transferred to the hospital for rehabilitation on postoperative day 37. The optimal surgical technique should be considered according to the degree of calcification and the patient's background in each case, as grafts are often highly calcified in cases of reoperation after homograft replacement.

Background: A review committee for unapproved and off-label drugs with high medical needs determined that the indication of fibrinogen concentrate for cardiovascular surgery would be publicly acceptable in 2021. However, the Japanese Society of Cardiovascular Surgery is required the conduct of several surveys demonstrating that fibrinogen concentrate can be used properly in medical settings. A questionnaire concerning the use of fibrinogen concentrate in cardiovascular surgery was one such required survey. Methods: A questionnaire concerning the use of fibrinogen concentrate was conducted in December 2021 at 551 certified training facilities of the Japanese Board of Cardiovascular Surgery, and responses were received from 375 facilities (68%). Results: Fibrinogen concentrate was used in 98 centers (26%). Aortic surgery (thoracic/thoracoabdominal) (50%) and cardiac redo surgery (24%) were eligible common surgeries requiring fibrinogen concentrate, and the intraoperative measurement of fibrinogen levels was performed in 77% of centers. The triggers for the use of fibrinogen concentrate were a fibrinogen level <150 mg/dl in 30%, <100 mg/dl in 20% and massive bleeding tendency in 40%. Of note, only 39 facilities (10%) were able to prepare cryoprecipitate in-hospital, and 34 centers (9%) used it for cardiovascular surgery. One hundred and seven centers (29%) planned to apply for facility accreditation for the use of fibrinogen concentrate, and 40 facilities (10%) answered that they would decide based on the situation. The expected number of annual cases in which fibrinogen concentrate would be used for cardiovascular surgery reached 4,860 cases: <10 cases in 52 centers, 10-19 cases in 50 centers, 20-49 cases in 31 centers, 50-99 cases in 12 centers and ≥100 cases in 2 centers. Conclusion: We conducted a questionnaire on the use of fibrinogen concentrate. Intraoperative fibrinogen level measurement was performed at approximately 80% of institutions, and the annual number of cases likely to use fibrinogen concentrate was predicted to reach about 5,000 cases. However, only 10% of centers used cryoprecipitates prepared in-hospital.

Objective：This study aimed to determine the difference in knee joint range of motion (ROM) and coefficient of variation (CV) during preoperative single-leg squatting in patients who developed ipsilateral lower limb anterior cruciate ligament (ACL) re-injury months after ACL reconstruction and in those who did not have the injury.Methods：Participants included 38 patients with non-contact ACL injuries. All patients underwent single-leg squatting the day before ACL reconstruction. Knee joint ROM and CV were assessed during single-leg squatting using a three-dimensional motion analysis system. We investigated the occurrence of ACL reinjury in the ipsilateral lower limb approximately 30 months after ACL reconstruction. Knee joint ROM and CV were then compared between the postoperative and non-injury groups.Results：The postoperative injury and non-injury groups included 9 and 29 patients, respectively. The knee internal/external rotation ROM and CV of knee varus/valgus ROM were greater in the postoperative injury group than in the postoperative non-injury group.Conclusion：During single-leg squatting before ACL reconstruction surgery, the knee internal/external rotation ROM and CV of knee varus/valgus ROM were suggested to be points of evaluation when considering ACL re-injury prevention.

Mitral valve surgeries for cases with mitral annular calcification (MAC) are challenging because of the operative complications. For a case of MS with MAC, we achieved mitral valve plasty by ultrasonic decalcification alone. An 82-year-old male with edema and dyspnea was diagnosed with AS and MS with MAC. MAC was so severe that MVR was challenging. There were calcifications at the anterior commissure and the anterior mitral leaflet (AML), and removal of them was expected to improve the valve function. Therefore, anterior commissurotomy and ultrasonic decalcification of the anterior commissural annulus was performed using cavitron ultrasonic surgical aspiration (CUSA). Following the resection of the aortic valve, we carried out decalcification of the AML through the aortic valve orifice. After AVR, a trans-esophageal echocardiogram showed MS was ameliorated. Two years after surgery, recurrence of MS was not recognized. Some mitral cases with MAC can be treated by only decalcification to avoid risky valve replacement.

A 85-year-old man with an abnormal shadow on X-ray was given a diagnosis of aortic arch aneurysm by CT scan. Preoperative additional careful examinations revealed that his dominant vertebral artery was the left one and he had an allergy to metals such as platinum, tin and zinc. He underwent thoracic endovascular aortic repair (TEVAR) after revascularization of left vertebral artery by bypass grafting between bilateral axillary arteries and the left common carotid artery with a T-shape graft. Because of the position of the origin of the left vertebral artery from the left subclavian artery was comparatively proximal part, we made it transposition more distally to occlude the LSA by ligation. We selected conformable GORE® TAG® for zone-1 TEVAR because the stent graft, which was not composed of allergic metals, contained only less allergic metals than any other devices commercially available. More than two years have passed since his discharge and he was followed as an outpatient without any allergic symptom and other remarkable complications. Here, we report a rare case of 2 debranching TEVAR for aortic arch aneurysm with metal allergy.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory disease of the gastrointestinal tract, with increasing prevalence worldwide. IBD Ahead is an international educational program that aims to explore questions commonly raised by clinicians about various areas of IBD care and to consolidate available published evidence and expert opinion into a consensus for the optimization of IBD management. Given differences in the epidemiology, clinical and genetic characteristics, management, and prognosis of IBD between patients in Japan and the rest of the world, this statement was formulated as the result of literature reviews and discussions among Japanese experts as part of the IBD Ahead program to consolidate statements of factors for disease prognosis in IBD. Evidence levels were assigned to summary statements in the following categories: disease progression in CD and UC; surgery, hospitalization, intestinal failure, and permanent stoma in CD; acute severe UC; colectomy in UC; and colorectal carcinoma and dysplasia in IBD. The goal is that this statement can aid in the optimization of the treatment strategy for Japanese patients with IBD and help identify high-risk patients that require early intervention, to provide a better long-term prognosis in these patients.

We report a rare case of primary cardiac undifferentiated pleomorphic sarcoma with invasion to the posterior mediastinum, for which partial resection of the tumor in the left atrium had already been carried out twice. After remission for about three years, recurrence in the atrial wall involving the mitral valve posterior leaflet required a third surgical resection following mitral valve replacement.

We report the successful treatment of an 81-year-old woman after a difficult diagnosis of mitral valve regurgitation resulting from partial rupture of the posterior papillary muscle. The patient, with a chief complaint of dyspnea, was admitted to our hospital in October, 2010. Echocardiography revealed severe MR and an oscillating abnormal mass attached to the mitral posterior leaflet was assessed as vegetation. Her general condition worsened and coronary angiography revealed 90% stenosis at #6 and 99% stenosis at #12. Partial papillary muscle rupture of post acute myocardial infarction was ruled out. Urgent surgery was performed. It is found that tissue we had assessed as vegetation was a part of the posterior papillary muscle with no signs of infection. MVP with quadrangular resection (P3), annuloplasty and CABG (LITA-LAD, SVG-OM) was performed. The patient was discharged on the 28th postoperative day. Echocardiography showed no MR for four years after the surgery.
