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 31-year-old woman had an aneurysm of the brachiocephalic artery and aortic regurgitation due to aortitis syndrome. As C-reactive protein (CRP) levels were high (27.5mg/dl), steroid therapy was initiated. After CRP became negative, the brachiocephalic aneurysm was repaired using a GELWEAVE® Y-graft, and the aortic valve was replaced with an ATS® mechanical valve. Regional cerebral oxygenation (rSO2) was monitored during the operative period. The level of rSO2 did not change during the period when the brachiocephalic artery was clamped, resulting in no cerebral damage after the operation. Homer's syndrome appeared after the operation but the symptoms gradually improved spontaneously. A mechanical valve was chosen because the patient did not want to undergo a reoperation. No cerebrovascular event occurred after the operation and the patient was discharged on the 28th postoperative day.

We report mitral valve replacement (MVR) in a patient who had undergone left pneumonectomy for thoracic empyema 8 years previously. A 75-year-old man had heart failure due to mitral valve regurgitation and medication therapy was initiated. Although the heart had shifted to the right side, MVR was performed using a SJM valve with primary median sternotomy. The tracheal intubation tube was removed 17h after the operation, and the patient was discharged on the 43rd postoperative day. Careful preoperative assessment, preoperative control of heart failure, and careful attention to perioperative fluid management are important components of successful clinical management.

The operation for constrictive pericarditis after coronary artery bypass grafting (CABG) needs complete pericardiectomy without injury to the bypass graft. A 60-year-old man had pleural effusion a month after CABG. Right atrial pressure (RAP), right ventricular pressure (RVP), and pulmonary capillary wedge pressure (PCWP) were elevated and RVP showed a dip and plateau sign on cardiac catheterization. We diagnosed heart failure due to constrictive pericarditis following CABG. Pericardiectomy was performed using a cardiopulmonary bypass through a median sternotomy. The Harmonic Scalpel was useful for dissecting the pericardium. After the operation, it took a month for the patient to improve. RAP, RVP and PCWP were decreasing, and the dip and plateau sign of RVP was improved. The pleural effusion disappeared and the patient was discharged on the 73rd postoperative day.

Right-sided infective endocarditis (IE) accounts for 5% to 10% of all IE. Compared with left-sided IE, antibiotic treatment is effective in about 70% of cases. The timing of surgical treatment for right-sided IE is therefor controversial. A 26-year-old woman had suffered from tricuspid valve endocarditis with DIC. There was no evidence of any previous cardiac event or dental treatment. Echocardiography showed a large vegetation attached to the anterior leaflet of tricuspid valve with moderate tricuspid regurgitation. We removed the vegetation with a part of the anterior leaflet and performed tricuspid valvuloplasty and annuloplasty. The patient had an uneventful postoperative course and received intravenous antibiotic treatment for a further 4 weeks.

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.
