A case of clinical1y unsuspected nonspecific inflammatory aortic regurgitation is reported. A 69-year-old female patient underwent aortic valve replacement for aortic regurgitation. Pathological examination of resected aortic valve showed abscess formation and inflammatory granulation tissue in the non-coronary cusp. Therefore, we diagnosed nonspecific inflammatory aortic regurgitation. It is generally considered that the use of prednisolone for vasculitis syndrome is effective ; however, for nonspecific inflammatory aortic regurgitation its use has not been established. Prednisolone treatment could be an option for nonspecific inflammatory aortic regurgitation.

A 56-year-old woman was referred to our hospital due to anorexia. An echocardiogram demonstrated severe mitral valve regurgitation and vegetation located on the valve. We diagnosed infective endocarditis and started to treat with antibiotics. During antibiotics treatment, cerebral hemorrhage was caused by rupture of an infectious cerebral aneurysm. She was treated by surgical operation. Waiting for cardiac surgery, she had sudden chest pain. Electrocardiogram examination demonstrated an anterior acute myocardial infarction. Emergency coronary angiogram revealed complete obstruction of the left anterior descending coronary artery. She was successfully treated with thrombus aspiration using a catheter device and stenting. However, she was in cardiogenic shock and her blood pressure could not be maintained with catecholamine and IABP. We performed emergency mitral valve replacement. After surgery, the circulation dynamics improved and she was discharged from the hospital.

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.

A 51-year-old man, with an abnormal shadow on chest X-ray film, was found to have a right-sided aortic arch with mirror-image branching and Kommerell's diverticulum. Neither congenital heart anomalies nor vascular ring was observed. We performed descending aorta replacement with a Hemashield^TM 24-mm graft, because the trachea and esophagus were compressed by the diverticulum, and to eliminate the risks of aneurysmal change or rupture. The operation was performed through right thoracotomy, and with total CPB under deep hypothermic circulatory arrest. The patient was discharged on the 18th postoperative day. This is rare adulthood case of right aortic arch with Kommerell's diverticulum and no anomalies in the heart.

A 77-year-old man was hospitalized for a proximal anastomotic aneurysm 9 years after surgery for an abdominal aortic aneurysm. The aneurysm was located 3cm distal to the renal artery. The maximum diameter was 55mm. His medical history included a reoperation for the proximal anastomotic aneurysm and cerebral infarction. Endovascular stent grafting was performed because it was possible anatomically. Postoperatively, no endoleak nor migration were found. At present, the patient is being followed up regularly in the outpatient department. Endovascular stent graft placement can be an effective method for reoperation cases of an abdominal aortic aneurysm, and if it is possible anatomically, it should be attempted.

A 67-year-old man was referred to our department for surgical treatment of ischemic cardiomyopathy. Chest X-ray showed cardiomegaly with a cardiothoracic ratio of 62% and pulmonary congestion. CAG revealed multiple obstructive lesions in the left coronary artery system. LVG and UCG showed ventricular dilatation and dysfunction. ECG showed complete left bundle branch block with a QRS duration of 180ms. He underwent autologous bone marrow cell implantation and biventricular pacing concomitant with coronary artery bypass grafting. He is doing well after 15 months without any complications. Combination with therapeutic angiogenesis and cardiac resynchronization therapy may contribute to the development of new regenerative strategy for patients with severe ischemic cardiomyopathy.

We investigated the effects of rewarming speed on cerebral circulation and oxygen metabolism during cardiopulmonary bypass (CPB). Twenty-four adult patients who had undergone open heart surgery with moderately hypothermic CPB were divided into two groups. In the slow rewarming group (group S), the rates of increase of blood temperature were under 0.1°C/min. In the rapid rewarming group (group R), they were more than 0.1°C/min. Mean blood flow velocity in the middle cerebral artery (mean MCAv) was measured by transcranial Doppler ultrasonography, and the index of cerebral oxygen consumption was evaluated by Doppler-estimated cerebral metabolic rate for oxygen (D-CMRO₂). The change of oxyhemoglobin level in the brain (Oxy Hb) was monitored by near-infrared spectroscopy. In group S, mean MCAv and D-CMRO₂ changed in a parallel manner following the changes of the rectal temperature throughout the periods, and mean MCAv was always higher than D-CMRO₂. In group R, however, the rate of increase of D-CMRO₂ was more rapid than that in group S from the beginning of rewarming, and D-CMRO₂ exceeded the level of mean MCAv just before termination of CPB. In addition, Oxy Hb in group R showed more rapid changes than that of group S. In conclusion, rapid rewarming during CPB may cause the disruption of cerebral flow-metabolism coupling.

We report a case of aneurysm localized to the noncoronary sinus of Valsalva with moderate aortic regurgitation (AR). The patient was a 49-year-old woman who had been suspected to have some kind of connective tissue disorders. She underwent an aortic root remodeling procedure to replace the isolated, unruptured and extracardiac aneurysm and the ascending aorta. Postoperative angiogram showed no aneurysm and improved AR. This procedure was able to preserve her own aortic valve and normal sinuses of Valsalva and enable her to obtain better quality of life, although progression of the enlargement of the aorta or AR requires careful follow-up.

We experienced two rare cases of acute aortic dissection with leg ischemia after Y graft repair of the abdominal aortic aneurysma. Case 1 was a 63-year-old woman who had received Y graft repair at age 55, and case 2 was a 28-year-old man with Marfan's syndrome who received a Y graft repair at age 21. Both patients sustained DeBakey type I dissections terminating at the suture line of the Y graft and had symptoms of acute arterial occlusion of bilateral lower extremities. Emergency operation was performed 8 hours after onset in case 1 and 6 hours after in case 2. Case 1 could not be weaned from cardiopulmonary bypass because of intraoperative rupture and acute heart failure, but case 2 underwent successfully aortic root replacement and total arch replacement under selective cerebral perfusion.

A 64-year-old man with a history of anterior blunt trauma 10 years previously was admitted to our hospital complaining of general fatigue. A plain chest roentgenogram showed pericardial calcification. Computed tomography and echocardiography showed the mass to be a calcified capsule in the anterior mediastinum compressing the right side of the heart. He underwent an operation through a median sternotomy. The mass was an organized hematoma encapsulated by a calcified fibrous and serous layer of the pericardium. The hematoma was resected together with the calcified pericardium under cardiopulmonary bypass. His postoperative course was uneventful. He had no history of hemopericardium but had experienced blunt chest trauma that seemed to have induced the subsequent localized constrictive pericarditis.
