Studies have shown that postoperative disseminated intravascular coagulopathy (DIC) occurs in some patients with cardiac disease, acute aortic dissection, and ruptured abdominal aortic aneurysm. The specific pathophysiology of DIC in these settings are related to low cardiac function, shock, infection and sepsis as well as activation of coagulation cascade in the aneurysm sac or dissected aorta. A soluble form of recombinant human thrombomodulin (rhsTM) was approved in 2008 for the treatment of DIC. This report describes the safety and efficacy of rhsTM for the treatment of DIC in patients with cardiovascular disease operated in our department. Between October 2010 and March 2012, 35 patients with postoperative DIC were treated with rhsTM. Diagnosis of DIC was based on the diagnostic criteria for DIC of the Japanese Association for Acute Medicine (JAAM). During the first 6 months of the study period, after a diagnosis of DIC was made, the patients were treated with gabexate mesilate and antithrombin III, and if patients showed no improvement with conventional treatment, they received rhsTM for 6 days. During the last 10 months of the study period, patients received rhsTM soon after a diagnosis of DIC was made. Twenty seven patients survived for 28 days after rhsTM treatment, and the mortality rate was 22.9% (8/35). Patients who survived showed improvement in acute phase DIC scores, FDP levels, D-Dimer, fibrinogen and platelet counts during rhsTM treatment, but no improvement was observed in patients who died. No serious adverse events were found up to 28 days after the start of rhsTM administration. In conclusion, this study showed no adverse events of rhsTM, and further studies are needed to confirm that rhsTM administration is an effective therapeutic modality in the management of DIC after cardiovascular surgery.

In a 63-year-old male patient Jehovah's witness, IABP was introduced due to acute myocardial infarction and cardiogenic shock, and PCI (BMS) was carried out to CAG #7 100%. Stent placement was carried out and his hemodynamics stabilized. A left-to-right shunt was observed upon carrying out LVG, so the patient was referred to our hospital for surgery purposes due to a diagnosis of ventricular septal perforation (VSP). Upon transferring the patient to hospital, his PA pressure elevated to 53 mmHg although the blood pressure was maintained, and no findings of right heart failure were observed. His respiratory condition was stable. Emergency surgery was considered, but the patient was taking Clopidogrel following PCI, and so VSP repair (extended endocardial repair) was carried out following 4 days discontinuation of Clopidogrel. Preoperative anemia was not observed ; however, postoperative hemorrhagic anemia improved due to iron preparation administration, and the patient was discharged from hospital 22 days following surgery without blood transfusion.

Background/Aims: Proteinase 3 antineutrophil cytoplasmic antibody (PR3-ANCA) is a serologic marker for granulomatosis with polyangiitis. However, recent studies have also shown their role as diagnostic markers for ulcerative colitis (UC). This study was performed to investigate the clinical roles of PR3-ANCAs in the disease severity, disease extension, and clinical course of UC. Methods: Serum PR3-ANCAs were measured in 173 UC patients including 77 patients with new-onset patients UC diagnosed within 1 month, 110 patients with Crohn’s disease, 48 patients with other intestinal diseases, and 71 healthy controls. Associations between the PR3-ANCA titer and clinical data, such as disease severity, disease extension, and clinical course, were assessed. The clinical utility of PR3-ANCA measurement was evaluated by receiver operating characteristic (ROC) analysis. Results: PR3-ANCA ≥3.5 U/mL demonstrated 44.5% sensitivity and 95.6% specificity for thediagnosis of UC in all patients. PR3-ANCA positivity was more prevalent in the 77 new-onset UC patients (58.4%). In this group, the disease severity and extension were more severe in PR3-ANCA positive patients than in PR3-ANCA negative group (p<0.001). After treatment, the partial Mayo scores were significantly decreased with the PR3-ANCA titers. The proportion of patients who required steroids for induction therapy was significantly higher among PR3-ANCA positive than negative group. ROC analysis revealed that PR3-ANCA ≥3.5 U/mL had 75% sensitivity and 69.0% specificity for steroid requirement in new-onset UC patients. Conclusions Our results indicate that PR3-ANCA measurement is useful not only for diagnosing UC but also for evaluating disease severity and extension and predicting the clinical course.

We present the case of a 72-year-old male with Inspiris RESILIA aortic valve (Inspiris) transvalvular leakage during surgical aortic valve replacement (AVR). The patient initially underwent AVR for aortic regurgitation with a bicuspid aortic valve at the age of 64. By the age of 72, the valve had deteriorated and it was assessed that redoing the AVR was necessary. The Inspiris was inserted in the supra-annular position using the non-everting mattress suture technique with a COR-KNOT. During weaning off from cardiopulmonary bypass, transesophageal echocardiography (TEE) captured unfamiliar turbulent flows from the three stent posts. Further TEE revealed that these flows originated from the base of the stent posts, which gradually decreased and disappeared by the end of the surgery after administration of protamine. The patient has been discharged uneventfully. Paravalvular leakage has not been observed during the postoperative course and we could not find TVL in TEE 2 months postoperatively. While considering the detailed mechanism, it is possible that there is no need for re-exploration concerning three directional TVL in the Inspiris.

A 65-year-old male was diagnosed with severe aortic stenosis with an indication for surgery and referred to our department. The patient opted for aortic valve replacement using a bioprosthesis. Due to the patient's relatively small native aortic valve area, a concurrent root dilatation maneuver (Bo Yang method) was performed to prevent patient-prosthetic mismatch and to allow for the implantation of a sufficiently larger bioprosthesis, facilitating the valve-in-valve procedure. The successful implantation of an Inspiris 25-mm bioprosthesis was achieved. Post-operative 3D-computed tomography revealed no tilting or misalignment of the bioprosthesis, and a properly sized, undistorted Valsalva sinus was observed. Aortic valve replacement using the Bo Yang root enlargement technique is considered a promising alternative for relatively younger patients requiring aortic valve intervention.
