The valvular function after aortic valve replacement was examined using Doppler echocardiography and changes in serum lactate dehydrogenase (LDH) and free hemoglobin levels were assessed. Data for the ATS Medical open pivot prosthetic valve were compared with those of the St. Jude's Medical prosthetic (SJM) valve, a similar bileaflet valve. These have been used in the past 5 years. There were 23 patients with ATS valves (13 men and 10 women, with a mean age of 60.4±13.8 years) and 16 patients with SJM valves (10 men and 6 women, with a mean age of 61.4±8.7 years). The left ventricular diastolic diameter index (LVDdI), left ventricular systolic diameter index (LVDsI), % fractional shortening (%FS) and left ventricular mass index (LVMI) were determined by echocardiography. The peak pressure gradients of the aortic prosthetic valves were calculated by a simplified Bernoulli equation. Postoperative LVDdI, LVDsI and LVMI were not significantly different in the ATS group and the SJM group. However, the %FS of the ATS group was significantly higher than that of the SJM group with aortic stenosis. The pressure gradients at the aortic prosthetic valve position were not significantly different between ATS and SJM valve in the 19-mm, 21-mm and 23-mm size. Postoperative improvement or recovery of the serum LDH level was observed significantly more frequently in the ATS group than the SJM group (p<0.005). The free hemoglobin level of the ATS group was also lower than that of the SJM group (p<0.005). We demonstrated satisfactory valvular function of the ATS valve compared with the SJM valve. Postoperative improvement of hemolysis was observed significantly more frequently and more rapidly in the ATS valves.

A 77-year-old woman was given general anesthesia for an ascending aortic aneurysm operation and went into anaphylactic shock. The operation was canceled. Vecuronium, pancuronium, protamine and famotidine revealed positive prick test reactions. Ascending aortic replacement underwent under minimum dose of heparin for cardiopulmonary bypass (CPB). Heparin was injected immediately before CPB (2.5mg/kg) and nafamostat mesilate was injected continuously during CPB (2mg/kg/h). The ACT value was over 1, 400sec during CPB. However, protamine was not used after CPB. The operation time was 4h and 30min. CPB time was 1h and 26min. After the patient returned to the ICU, bleeding from the chest drainage tubes increased temporarily. The bleeding decreased gradually after administration of FFP and MAP.

Primary cardiac angiosarcoma is very rare and its prognosis was reported to be very poor (average survival period 7 months). A 46-year-old woman with angiosarcoma was admitted for recurrent symptoms of cardiac tamponade. Surgical excision of the tumor was performed 5 months after initial presentation and irradiation therapy was added. Thereafter, immunotherapy, and transcatheter arterial embolization were performed for liver metastasis. Despite this multidisciplinary therapy, she passed away 355 days after surgery. In our report, we described our multidisciplinary approach to this highly malignant tumor and the treatment strategy was discussed.

An 80-year-old woman underwent lower and middle lobe resections of right lung in 1990 and 1998 because of lung cancers. There was no recurrence. In 2009, she presented with exertional dyspnea, and echocardiography showed grade III mitral regurgitation (MR). We diagnosed with congestive heart failure caused by MR. Her chest CT showed her mediastinum was shifted to the right and her heart was in the right thoracic cavity. We performed mitral valve plasty via right 7th intercostal thoracotomy. Post-operative respiratory condition was stable and she was extubated on the first postoperative day. Post-operative UCG showed trivial MR. She was discharged on the 14th day.

A questionnairing was conducted on those who had graduated from acupuncture schools for last three years. 288 questionnaires, that is, 28.8% of the total were answerd.
As the result, 41% of the graduates are practicing, 27% are working for institutions connected with acupuncture, and 28% are working in hospitals.
Combining present practitioners and those who are to start practice, it seems 76% of the graduates enter practice; most of the graduates aim at setting up practice. Which course to be taken makes the difference in medical charge, the number of patients, and their annual income.

Recent advances in both diagnostic and therapeutic technologies have caused dramatic changes in treatment strategy for esophageal cancer patients. In this lecture, we will introduce the advances in multimodal treatment for esophageal cancer, based on our own experiences. 1. Neoadjuvant chemotherapy (NAC) with Docetaxel/Cisplatin/5-fluorouracil (DCF) for node-positive esophageal cancer. Recently, in Japan, an efficacy of NAC for resectable advanced squamous cell carcinoma of the esophagus has been reported. DCF is expected to be a powerful alternative to cisplatin/5-fluorouracil. Our experience on neoadjuvant or induction DCF will be demonstrated. 2. Efficacy and safety of salvage esophagectomy after dCRT. Salvage esophagectomy is an almost only method to cure the patients with local failure after dCRT, although high mortality and morbidity rates have been reported. We performed 40 cases of salvage esophagectomy during the last 7 years and no hospital mortality has been experienced. Benefit of salvage surgery and procedures to decrease surgical risk will be discussed. 3. Basic research for individualized treatment. If an individualized treatment strategy can be established based on some predictive markers, both improved survival and preserved quality of life will be realized. We will demonstrate the possibility of epigenetic analysis (e.g., LINE-1 methylation level) as biomarkers to predict patient prognosis.

A 27-year-old woman was given a diagnosis of infectious endocarditis with severe tricuspid regurgitation. Despite adequate antibiotics therapy, her general condition did not improve, and moreover multiple pulmonary abscesses were detected by computed tomography. Therefore surgery was indicated. Surgery consisted of removal of vegetation and tricuspid valve plasty with autologous pericardial patch augmentation of the anterior leaflet. Tricuspid valve plasty was carried out without prosthetic materials. Her postoperative course was uneventful with only mild tricuspid regurgitation. One year after surgery, neither recurrence of infection nor worsening of tricuspid regurgitation was noted. This method could be a useful technique for young patients with severe infection.

We described a patient with free wall rupture followed by papillary muscle rupture due to acute myocardial infarction. A 69-year-old man was transferred complaining of transient unconsciousness. His clinical history, electrocardiogram, and chest CT showed myocardial infarction with free wall rupture indicated that several days had passed since the onset. Coronary angiography showed occlusion of the right coronary artery and severe stenosis of the left anterior descending artery. Since cardiac rupture was at inferior wall and hemorrhage wasn't active, repair of the rupture using fibrin glue and fibrin sheet and coronary artery bypass grafting to the left anterior descending artery was performed without cardiopulmonary bypass. On the 10th postoperative day, his arterial oxygen saturation suddenly deteriorated. Transesophageal echocardiography revealed papillary muscle rupture and severe mitral regurgitation. Emergency mitral valve replacement was performed. After two emergency operations, he gradually recovered and were discharged to home. In three months after discharge, he was admitted again due to congestive heart failure with left ventricular aneurysm at inferior wall and recovered in response of conservative treatment. Surgical experience of double rupture is rare. Based on this case, it may be necessary to perform reperfusion therapy toward even this case of recent myocardial infarction, to prevent papillary muscle rupture. It also may be better to use a patch on free wall rupture to prevent cardiac aneurysm.
