Abstract
Protein carbonyl groups in the stratum corneum may be used as a biomarker for skin photo-stress. To evaluate the relationship between the protein carbonyl to total protein (TP) ratio (carbonylation ratio) and skin photo-stress, the authors established a methodology by which protein carbonyl can be easily and highly sensitively analysed using an optical technique based on surface plasmon resonance (SPR). To collect the stratum corneum, tape stripping was employed. Firstly, the protein carbonyl was reacted with 2,4-dinitrobenzenesulfonic acid dihydrate, and the quantity of dinitrophenylated (DNP)-protein carbonyl was determined using an anti-dinitrophenyl (anti-DNP) antibody. The mass of DNP-protein carbonyl was measured using SPR. A truncated sampling-reporting cycle of <5 min allowed speedy reporting of DNP-protein carbonyl levels. A significant difference was observed in the protein carbonyl/TP ratio (carbonylation ratio) between a sun-protected area (mid-ventral arm) and a sun-exposed area (upper cheek, P < 0.05). Additionally, the carbonylation ratio of the sun-exposed area showed a higher value than that of the sun-protected area. It was suggested that the carbonylation ratio might be a useful index of skin photo-stress.

Abstract
BACKGROUND Preoperative autologous blood donation reduces exposure to homologous blood transfusions in cardiac surgery. The purpose of this study was to ascertain, how much volume of predonated autologous blood needed to avoid of homologous blood transfusion in scheduled off-pump coronary artery bypass grafting (OPCAB). METHOD Fifty patients underwent scheduled OPCAB. These patients donated 400 ml (group A, n = 30) or 800 ml (group B, n = 20) of autologous blood before operation. These patients donated at a rate of 400 ml per week. All patients were given an equal volume of saline solution at the time of autologous donation. RESULT There were no significant differences mean age, mean body weight, mean preoperative hematocrit values, mean graft number or mean volume of intraoperative blood loss between groups A and B. There was significant difference the mean postoperative day-7 hematocrit value (33.4 +/- 1.5% vs 38.7 +/- 1.5%, p < 0.05). The rates of avoiding homologous blood transfusion were 63.3% in group A and 100% in group B (p < 0.05). CONCLUSIONS Autologous blood transfusion was effective for reducing the homologous blood requirement. We believe that 800 ml predonation is sufficient to avoid homologous blood transfusion in scheduled OPCAB, further patients with cardiovascular disease including severe coronary artery should be donated with the administration of saline.

Abstract
BACKGROUND The evaluation of cerebral perfusion during off-pump coronary bypass grafting (OPCAB) has not been clarified. The aim of this study was to investigate the predictive value of neurobiochemical markers of brain damage and cerebral perfusion with respect to the neuropsychological outcomes after OPCAB. METHODS Ten patients (4 males and 6 females) underwent OPCAB. All patients were performed brain CT preoperatively and 7 days postoperatively. We excluded the patients with cerebralvascular disease from this study. A 5.5 Fr oximetric catheter was placed in the jugular bulb, and we measured continuously SjO2 and mean arterial blood pressure during OPCAB. Venous serum level of neuron specific enolase (NSE) was measured preoperatively and 24 hours after skin closure. RESULTS There was correlation between mean blood pressure and SjO2 during anastomoses. The mean blood pressure during anastomoses of left anterior descending coronary artery (LAD), circumflex coronary artery (Cx), right coronary artery (RCA) were 68.6 +/- 12.9 mmHg, 60.9 +/- 9.3 mmHg, 64.1 +/- 14.1 mmHg. The SjO2 during anastomoses of LAD, Cx, RCA were 57.3 +/- 10.9%, 48.6 +/- 9.8%, 57.7 +/- 18.2%. There is tendency that the SjO2 during anastomosis of Cx was lower than others. No patients died, and there was no permanent neurologic deficit. Postoperatively, 2 patients had abnormal high NSE level. CONCLUSION Intraoperative continuous cerebral oxygen desaturation monitoring seems to be useful monitor for neuropsychological outcomes after OPCAB.

Abstract
BACKGROUND Preoperative autologous blood donation is commonly used to reduce exposure to homologous blood transfusions among patients undergoing elective cardiac surgery. The purpose of this study was to ascertain how much volume of predonated autologous blood need to avoid of homologous blood transfusion in cardiac procedure. METHODS One hundred twenty-eight patients underwent scheduled cardiac procedure between January 1998 and December 1999. Group 1: 400 ml predonated, operation without cardiopulmonary bypass (CPB) [n = 33], group 2: 800 ml predonated, operation without CPB (n = 23), group 3: 800 ml predonated, operation with CPB (n = 36), group 4: 1,200 ml predonated, operation with CPB (n = 36). Surgical procedures underwent only off-pump coronary artery bypass grafting (OPCAB) in groups 1 and 2. In groups 3 and 4 included coronary artery bypass grafting (CABG), valve replacement, CABG + valve replacement and atrial septal defect repair. RESULTS There were no significant differences in mean body weight, mean preoperative hematocrit values or mean volume of intraoperative blood loss between groups 1 and 2. There were no significant differences in mean age, mean body weight, mean preoperative and postoperative day-7 hematocrit values, mean volume of intraoperative blood loss or mean CPB time between groups 3 and 4. The mean postoperative day-7 hematocrit value was significantly lower in group 1 than in group 2. Homologous blood transfusion was avoided in 63.6% of those with predonation of group 1 versus 100% at group 2 (p < 0.05), 86.1% at group 3 versus 94.4% at group 4 (p < 0.05). In group 3, all patients who underwent redo operation or CABG + valve replacement needed homologous blood transfusion. CONCLUSIONS Autologous blood transfusion is effective for reducing the homologous blood requirement. It also seems that predonation of 800 ml may be sufficient to avoid homologous blood transfusion in cardiac surgery, however predonation of 1,200 ml is desirable in cases of redo operation or CABG + valve replacement.

Abstract
BACKGROUND This study investigated the usefulness of quantitative assessment of Thallium-201 stress redistribution myocardial scintigraphy combined with quantitative assessment of regional left ventricular function using the centerline method for predicting of recovery regional left ventricular function following myocardial revascularization. METHODS Twenty patients with chronic total obstruction of the proximal portion of left anterior descending artery and/or right coronary artery were studied. Percent Tl-uptake method was used to evaluate myocardial viability before CABG. Regional LV function was evaluated before and after CABG with the centerline method. The territory of LAD was defined by chords 10 to 58 and that of RCA was defined by chords 59 to 80 in the centerline method. The parameter of regional left ventricular function was the mean (SF-Av.)/SD of each LAD and RCA territory. RESULTS In cases showing a % uptake value under 50%, the preoperative value of (SF-Av.)/SD was -3.18+/-0.74 and postoperative value was -2.63+/-0.8 1. The difference between these values was not significant. When the %uptake value over 50%, the preoperative value of (SF-Av.)/SD was -2.80+/-0.49 and the postoperative value was -2.27+/-0.28. The postoperative value was significantly higher than the preoperative value(p=0.007). CONCLUSIONS Even in cases of severe left ventricular dysfunction, regional left ventricular function improved if the value of % uptake in the redistribution Thallium imaging was 50% or over. Quantitative analysis of myocardial scintigraphy combined with quantitative analysis of left ventriculography is a useful method for predicting recovery of regional left ventricular function following myocardial revascularization.

Abstract
A 42-year-old female had suffered from chest pain for approximately 1 month, and was admitted with unstable angina pectoris. Emergent coronary angiography showed an isolated 75% stenosis of the left coronary ostium. Repair of ostial stenosis by vein patch angioplasty was done by the transactional superior approach. Postoperative catheterization revealed an expanded left coronary orifice and the patient was discharged without any complications. We have experienced 2 other patients of isolated left coronary ostial stenosis, who had undergone double coronary artery bypass grafting. Long-term coronary angiography showed regression of ostial stenosis in 1 patient, and no progression of new lesions in either. These results suggest that direct vein patch angioplasty of the ostial lesion is an alternative procedure for isolated left coronary ostial stenosis.

Abstract
BACKGROUND The surgical risks associated with ischemic mitral regurgitation are thought to be greater than those for other forms of mitral regurgitation. We have performed mitral valve replacement using the St. Jude Medical bileaflet prostheses with preservation of both leaflets, along with all of the chordae tendineae and papillary muscles. The aim of this study was to retrospectively evaluate mitral valve replacement with preservation of both mitral valves with respect to long-term clinical results and left ventricular performance. METHODS Between January 1, 1988 and February 29, 2000, 15 patients were operated on for ischemic mitral regurgitation. There were 7 males and 8 females, and the mean age was 69.7+/-8.1 years. The preoperative variables showed clinical deterioration of the state, such as emergency operation in 40% of the patients, more than NYHA functional III class in 93% of patients, cardiogenic shock in 47% of the patients, a mean left ventricular ejection fraction of 36.8%, and a mean left ventricular end-systolic volume index of 116.7 ml/m2. RESULTS There were 5 (33.3%) hospital deaths during the follow-up period including 1 early death and 1 (10%) late death during the follow-up period. Thus, the actuarial survival rate after 5 years for the whole was 60%. However, the left ventricular dimensions and left ventricular fractional shortening, even if in patients with profound depressed left ventricular function preoperatively, showed maintenance of the cardiac function. CONCLUSIONS These results suggested that mitral valve replacement using the St. Jude Medical prostheses with preservation of both leaflets and all chordae tendineae and papillary muscles might be a procedure of choice for ischemic mitral regurgitation.

Abstract
Off-pump coronary artery bypass grafting (OPCAB) is clearly preferable for patients with extracardiac complications. The aim of this study was to evaluate the initial outcome of OPCAB, and its validity for patients with extracardiac complications. One hundred and fifty-seven consecutive coronary artery bypass graft (CABG) patients were divided into two groups: 30 OPCAB patients and 127 on-pump CABG patients. The early outcomes of the two groups were compared. Preoperatively, OPCAB patients had more extracardiac risk factors than on-pump CABG patients. There were no differences in age or cardiac function between the groups, but the off-pump group had a higher incidence of previous surgery, cerebrovascular disease, and renal failure. There were no differences in graft patency, stroke, or mortality between the two groups, even though the OPCAB patients had more risk factors than the on-pump patients. Our initial experience with OPCAB showed that it is acceptable for high-risk patients in view of the serious nature of their extracardiac condition.

Abstract
A 36-year-old Japanese man was hospitalized with coughing and exertional dyspnea (NYHA class I). He was diagnosed as having congestive heart failure, and was treated with diuretics and a beta-adrenergic blocking agent. He responded well to the treatment and his symptoms completely disappeared within a few days. Based on his clinical, laboratory, and molecular genetic findings, he was diagnosed as having X-linked dilated cardiomyopathy (XLDCM). He was found to have a large deletion in the dystrophin gene, involving exons 45-55. This is the first report on a Japanese XLDCM patient with a mutation in the central hot-spot region of this gene.

Abstract
OBJECTIVE Cerebrovascular disease is commonly associated with coronary artery disease and is a major risk factor for cardiac surgery. Concomitant coronary artery bypass grafting and carotid endarterectomy may reduce the risk of stroke; however, this staged operation is effective only for extracranial lesions. The strategy for on-pump coronary artery bypass grafting for patients with intracranial vascular stenosis is still controversial. METHODS The subjects were 157 consecutive candidates for coronary artery bypass grafting who underwent computed tomography and digital subtraction cerebral angiography preoperatively to check for cerebrovascular disease. Additional single-photon emission computed tomography was performed to evaluate cerebral ischemia, according to the neurologist's request. Patients with diffuse intracranial vascular stenosis impossible to treat with percutaneous transluminal angioplasty underwent off-pump coronary artery bypass grafting. Patients with a circumflex coronary artery lesion first underwent percutaneous transluminal angioplasty for cerebral vascular stenosis followed by secondary on-pump coronary artery bypass grafting. RESULTS Three patients were selected for staged operations. Percutaneous transluminal angioplasty was performed for 4 intracranial stenotic lesions. All lesions were dilated successfully, and no complications developed during or after the procedure. All patients tolerated staged coronary artery bypass grafting and were extubated within 1 day without any mental disturbance. No further neurologic complication occurred, and computed tomography performed postoperatively revealed no significant changes. CONCLUSION Staged on-pump coronary bypass after percutaneous transluminal angioplasty for cerebrovascular disease may reduce the risk of stroke during cardiopulmonary bypass, and it is useful especially in patients with intracranial cerebrovascular disease.

Abstract
We report successful surgery for a thrombosed St. Jude Medical (SJM) valve 16 years after the initial mitral valve replacement even under conditions of satisfactory anticoagulation therapy. A 61-year-old-female had intermittent claudication and was admitted to our hospital for examination. The prosthetic valve sounds were normal to auscultation and the left ankle-pressure index was decreased to 0.6. Transthoracic echocardiography revealed no mitral regurgitation and a mean mitral valve gradient of 6-7 mmHg. Furthermore, transesophageal echocardiography revealed that one of the leaflets of the prosthetic valve was entirely immobilized at the closing position and a mobile soft tissue mass, 5 mm in diameter, was detected at the atrial side of the obstructed leaflet. Although 96,0000 IU of urokinase was administered intravenously for a week, we could not confirm any change in leaflet mobility. At the time of surgery, the posterior leaflet of the SJM valve, which was implanted at an anatomical orientation, was obstructed at the closing position with old and fresh thrombi. We decided upon replacement with a CarboMedics 29 M prosthetic valve. Postoperative medication consisted of warfarin plus low-dose aspirin. Generally, valve thrombosis occurs within 5 years after valve replacement. However, valve thrombosis is possible even in a reliable SJM valve and as long as 16 years after replacement. Therefore, the implantation of an SJM valve at an anti-anatomical orientation might lower the incidence of valve thrombosis in addition to life-long anticoagulation therapy.

Abstract
Aortic dissection etiology involve many factors that are difficult to identify clearly. We report a 47-year-old man who underwent a Bentall operation with reattachment of bypass grafts for a dissecting aneurysm (DeBakey type II) 4 years after combined triple coronary artery bypass grafting and mitral valve replacement. This case appeared to be associated with factors leading to dissecting aneurysm although it remains unclear which was more influential congenital bicuspid aortic valve or proximal anastomosis of venous grafts or both. This case suggests the need to consider appropriate timing in surgical intervention for cases of congenital bicuspid aortic valves and the selection of additional aortic valve replacement in initial surgery.

Abstract
BACKGROUND During the cardiovascular surgeries in elderly people, only a few cases can avoid the homologous blood transfusion, because of their preoperative anemic tendency and low hemopoietic abilities. We examined the capability to avoid the homologous blood transfusion in over 75 year old patients by the preoperative autologous blood collection. Sixty-six patients underwent scheduled cardiovascular surgery between January 1996 and December 1999. The groups were divided into three categories of preoperatively collected autologous blood amounts: high-amount (800-1,200 ml), medium-amount (200-800 ml), and low-amount (0 ml). Each group was divided into two subgroups in according to the use of cardiopulmonary bypass (CPB). There were no differences among the each group in age, body weight, or preoperative and postoperative day-7 hematocrit values. RESULTS Only 21.2% of patients could donate the expected blood amounts preoperatively. Mean volume was 641 ml. In groups used CPB, no patient was transfused homologous blood in high-amount group. On the contrary, 100% patients were donated in medium and low amount groups. In groups operated without CPB, homologous blood transfusion was required 14.3% in high-amount group, 25.0% in medium-amount group, and 83.3% in low-amount group. CONCLUSION It seems that predonation of more than 800 ml may be sufficient to avoid the homologous blood transfusion in using CPB operation and more than 400 ml in non using CPB operation.

Abstract
The subendocardial side of myocardium makes a major contribution to left ventricular (LV) contraction and is very susceptible to ischemia. In this study we sought to quantify regional wall motion during low-dose dobutamine stress echocardiography (DSE) by using the myocardial velocity gradient (MVG) derived from tissue Doppler imaging (TDI). We then compared the usefulness of subendocardial MVG with that of transmural MVG in detecting subtle wall motion abnormalities. Fourteen patients (single vessel disease = 6; normal coronary arteries = 8) underwent low-dose DSE (10 microg/ kg per min). M-Mode TDI of the LV posterior wall was recorded using a Toshiba SSA-380A combined with custom computer software, and analyzed for both subendocardial and transmural MVG. Visual estimation and transmural MVG failed to clearly demonstrate the differing responses between the nonischemic (systole: 3.0 +/- 0.8/s to 4.9 +/- 1.9/s, not significant; diastole: -4.3 +/- 1.3/s to -5.7 +/- 1.4/s, not significant; mean +/- SD, P versus ischemic segments) and ischemic (systole: 3.3 +/- 1.2/s to 3.8 +/- 1.0/s; diastole: -5.4 +/- 2.0/s to -5.3 +/- 1.1/s) segments during low-dose DSE. Subendocardial MVG demonstrated a significant change in the nonischemic segments (systole: 4.1 +/- 1.0/s to 7.7 +/- 2.2/s, P = 0.012; diastole: -6.5 +/-1.8/s to -11.3 +/- 2.2/s, P = 0.001), whereas the response remained unchanged in the ischemic segments (systole: 4.6 +/-2.4/s to 4.8 +/- 1.2/s; diastole: -7.0 +/- 1.9/s to -7.3 +/- 1.1/s). Subendocardial MVG, particularly diastolic subendocardial MVG, may serve as a useful indicator of subtle ischemic changes in wall motion induced by low-dose DSE.

Abstract
Two patients had percutaneous cardiopulmonary support (PCPS) used as a bridge to emergency surgery. A 66-year-old man admitted with profound cardiogenic shock underwent direct stenting under PCPS with the diagnosis of acute myocardial infarction of the left main trunk, with the intention of performing revascularization as soon as possible. Subsequently, double coronary artery bypass grafting was successfully accomplished. A 69-year-old woman, admitted with acute heart failure due to critical aortic stenosis, manifested cardiogenic shock while undergoing catheterization. PCPS was immediately instituted until the acute deterioration of her hemodynamic state could be reversed, and was continued uneventfully till aortic valve replacement was performed. These results suggest that the current PCPS system is an effective response to acute circulatory collapse and will contributed to the improved survival of patients.

Abstract
We report a case of successful off-pump surgical angioplasty in the left anterior descending coronary artery using a saphenous vein patch. A 49-year-old male with left main disease and severe cerebrovascular stenosis underwent off-pump bypass to the left anterior descending artery. Postoperative angiography showed anastomotic stenosis where balloon angioplasty was performed. However, it resulted in coronary perforation complicated with epicardial tamponade, and emergency off-pump surgical angioplasty was performed. This case demonstrated that coronary arterial rupture could be managed by surgical angioplasty without cardiopulmonary bypass when coronary artery perforation occurred.

Abstract
Between April 1995 and March 1998, we experienced 13 cases of Acute Myocardial Infarction due to Left Main Trunk Obstruction (LMT-AMI). Two cases died before emergent intervention. Eight cases underwent emergent intervention (Plain Old Balloon Angioplasty (POBA) in five cases, Stenting in 3 cases); 2 cases died of acute occlusion of POBA site, 1 case survived by only POBA, and the other 5 cases underwent following Coronary Artery Bypass Grafting (CABG). 3 cases underwent only CABG with stable hemodynamics condition by Intraaortic balloon pumping (IABP) support. In a result, seven of eight CABG cases survived. Emergent stenting made the hemodynamics before CABG stable, and six-month's follow up angiogram showed occluded bypass grafts and patent stented sites in two of three cases. The combination therapy of emergent stenting and CABG will have to be evaluated in future.

Abstract
A 80-year-old Japanese female was diagnosed to have angina pectoris and admitted to our hospital. She had been operated on with mitral valve replacement and coronary artery bypass grafting to right and circumflex coronary artery 4 years before. The coronary angiogram showed significant stenosis with severe calcification in the left anterior descending coronary artery, and it was unsuitable for catheter intervention. The patient also had stenotic left internal thoracic artery and multiple cerebral infarction, but successful off-pump subclavian-coronary artery bypass grafting using saphenous vein graft through small thoracotomy was performed without new neurological deficit. This procedure is useful for patients with left internal thoracic artery unsuitable for MIDCABG, due to quality, size, or injury during preparation.

Abstract
A 44-year-old male with Marfan's syndrome had undergone an initial operation for DeBakey type I acute aortic dissection with annulo-aortic ectasia. He had undergone replacement of the ascending aorta and aortic valve with a composite graft and reconstruction of the coronary artery by the Cabrol procedure. At 5 years after the initial surgery he experienced chest pain and was subsequently examined. Computed tomography revealed a pseudoaneurysm in the ascending aorta and the residual aortic dissection. The maximum diameter of the pseudoaneurysm was 85 mm and the maximum diameter of the aortic arch was 55 mm. The aortic arch was associated with an aberrant right subclavian artery. Angiography revealed that the pseudoaneurysm was caused by leakage at the coronary ostium-graft anastomoses. We repaired the anastomoses and performed total aortic arch replacement with reconstruction of four arch branches. The postoperative course was uneventful without any complications. We report this case because there have been few reports regarding arch replacement in cases with an aberrant right subclavian artery.

Abstract
Rupture of the aortic valve after a blunt chest trauma is rare. A 63-year-old man was injured in an automobile accident and was hospitalized elsewhere due to acute respiratory failure 4 days after the accident. On admission, he was intubated immediately. The patient did not respond to available medical treatments and was therefore transferred to our hospital. His condition was diagnosed as severe left heart failure, and an emergency operation was performed. The right coronary and non-coronary cusps were perforated and the commissure between the right coronary and non-coronary cusps was torn. The aortic valve was excised and a SJM 25 AEC prosthetic valve was inserted. The patient recovered well postoperatively.

Abstract
A 60-year-old male, who had been hospitalized with a Stanford type B acute aortic dissection 3 years ago, was admitted with severe disquiet caused by discomfort of the chest and the neck. Enhanced CT scans demonstrated the ascending aorta compressed by non-opacified false lumen, so-called "thrombosed dissection" or "closing aortic dissection", and normal descending aorta. Aortography showed no intimal tear in the ascending aorta and aortic arch. "Hibernation therapy" with pentobarbital was performed to be sedated over during 13 days. 29 days later follow-up CT scans showed reopacified false lumen and enlargement of the ascending aorta, although he had no complaints during the medical therapy. Large intimal tear just under the brachiocephalic artery and giant false lumen without reentry occupying the ascending aorta was found by the repeat aortography. Graft replacement of the ascending aorta was successfully performed. This case suggested that thrombosed dissection might have the risk of recanalization of clotted false lumen asymptomatically, and it would be important to take care of radiographic changes during the medical therapy even if the patient had no symptoms.

Abstract
We describe a 72-year-old patient with mediastinitis caused by Methicillin-resistant Staphylococcus aureus (MRSA) and Candida albicans after median sternotomy who was successfully treated with wound closure with pectoral musculocutaneous flap and closed continuous mediastinal irrigation. The irrigation device consisted of two pairs of irrigation and suction tubes which placed upper and lower half of mediastinum respectively, in which high rate irrigation technique (200 ml/h) was employed using 0.01% of Vancomycin hydrochloride as a base agent and additional 0.1% of Povidone-iodine in early phase and 0.01% of Fluconazole in late phase. After 12-days irrigation, the drainage culture turned negative and the wound was healed and tomographically granulated. High rate irrigation with sufficient concentration of antimicrobial agents selected according to each organism sensitivity could eliminate redundant irrigation and contribute to avoid antimicrobial toxication. We experienced also another four cases (two caused by MRSA, two caused by Serratia liquefaciens) treated successfully with this technique. These results led us to believe that continuous mediastinal irrigation technique could be carried out with safe and effectiveness so far as high rate irrigation with low concentration of Povidone-iodine is employed.

Abstract
A 55-year-old woman eighteen years after mitral valvular replacement with Delrin disc Björk-Shiley valve prosthesis underwent a reoperation of prosthetic valve replacement for the prosthetic malfunction due to disc defacement. The patient suffered from faintness and vertigo at rest. An echocardiographic examination showed a moderate mitral insufficiency with a normal disc movement. Precise examination on the removed prosthesis revealed accelerated defacement of disc margin which made the ring-disc clearance up to 0.35 mm and strut-shaped groove formation on the inlet surface of the disc occluder. These findings suggested a pronouncedly earlier disc wear than predicted by Björk and co-workers. We concluded, therefore, that a patient undergone a valve replacement with Delrin disc Björk-Shiley valve should be examined periodically by echocardiography even though being without any symptoms.

Abstract
A 46-year-old female who had undergone single CABG for BWG syndrome 11 years ago was referred to our hospital for paroxysmal atrial fibrillation. The roentgenogram showed slightly cardiomegaly and the enlargement of LA. Ischemic changes of ECG appeared at I, aVL, V5, V6, as inverted T wave, and low voltage R wave at V1-V4, but non Q wave. The thallium-201 emission computed tomogram at exercise revealed poor perfusion at apical region without redistribution pattern. Catheterization showed mitral regurgitation (grade III), big right coronary artery (RCA) arising from aorta, rich collateral to poor left coronary artery (LCA), and bypass graft was obstructed. The proximal end of LCA was closed, and didn't arise from both pulmonary artery and ascending aorta. In this cases, MVR only without re-CABG to LCA was selected and performed. Postoperative course was uneventful. The result of this case suggested that MVR was an effective surgical procedure for MR of BWG syndrome in the adult case and it was better to add CABG to LCA as much as possible if the ischemic region was large.

Abstract
A case of successful surgical removal of a primary malignant pericardial mesothelioma was reported. The patient was a 79-year-old man with a complaint of dyspnea at rest. Chest X-ray study showed enlargement of upper mediastinum. Echocardiogram, computed tomography and MRI revealed a giant mass occupying the pericardial space anterior to the heart with marked pericardial effusion. The right ventricle was severely compressed with this tumor. Total resection of the tumor was achieved because the tumor was localized without invading surrounding tissue. The tumor was 17 x 12 x 10 cm in size and 900 g in weight. Rare growth fashion as a distinct isolated mass was a key of successful outcome.

Abstract
A new catheter was developed for the cardio-renal assist during intra-aortic balloon counterpulsation. The catheter consists of both a large balloon of conventional IAB (TMP balloon) located at the distal end of the catheter and an additional small balloon 10 cm distant from the large balloon with common lumen and single shaft. Experimental study was carried out in the mock circulatory system simulating the descending aorta employing a conventional IAB catheter as a control. It was demonstrated that the flow in the mid portion between both balloons could be increased maximally by as much as 28% of that of the control under the continuous flow and 214% under the pulsatile flow. The double balloon catheter was considered to improve the renal perfusion as well as the coronary perfusion.

Abstract
Graft patency after coronary bypass surgery (CABG) was evaluated with stress 201-thallium scintigraphy (stress 201Tl) in 26 cases, including 13 cases using the left internal thoracic artery (LITA group) in situ and 13 cases with saphenous vein graft (SVG group). All of them had effort or unstable angina caused by LAD lesion without apparent infarction. Stress 201Tl using a symptom-limited, graded bicycle exercise test was performed before CABG and 1 month, 6 months to 1 year, 1 year to 1.5 years after surgery. Five tomographic images including the apical side of the area fed by the bypass anastomosed to LAD in short axial sections were picked out and piled up. Fan-shaped ROI was made on this area and % Tl uptake was calculated using the following formula. 201Tl counts in ROI--Background counts/Maximum counts--Background counts x 100 (%) The normal % Tl uptake calculated in the control group (n = 11) in this ROI was 68.2 +/- 4.8%. Preoperative % Tl uptake showed 49.3 +/- 0.2% in the LITA group and 54.3 +/- 13.2% in the SVG group. % Tl uptake of the SVG group 1 month after CABG was slightly higher than that of the LITA group, (62.0 +/- 7.0% vs. 56.3 +/- 7.6%). However 6 months to 1 year after, % Tl uptake of the LITA group increased to 60.8 +/- 6.4%, inspite of a tendency on the decrease of that in the SVG group, (59.0 +/- 8.5%), and further more, 1 year to 1.5 years after CABG, increased to 62.3 +/- 5.1% near the normal % Tl uptake of the control group and the SVG group decreased to 58.8 +/- 6.8%. This result suggested that arterial in situ bypass graft might have an auto-regulation and "growing property" corresponding to flow demand, and this helps the excellent long-term patency of arterial bypass grafts.

Abstract
The patient was a 72-year-old woman who was admitted with AMI. On the next day, a systolic murmur of Levine II/VI became audible on the left sternal border of the 5th intercostal space and VSP was diagnosed by the echocardiogram. The hemodynamics was comparatively stable, and so we scheduled the elective operation in the expectation of the healing of the infarction tissue. At the cardiac catheterization just before the operation, L-R shunt ratio was 64.9% and main PA was 41/18 (26) mmHg. Before the operation we marked the VSP position by Swan-Ganz catheter through the left ventricle and VSP closure and 2 CABG was performed. We concluded that this method was useful for the diagnosis and therapy of VSP.

Abstract
Four dialysis patients received aorto-coronary bypass grafting (CABG) at Fukuyama cardiovascular hospital from April 1989 to March 1992. We employed continuous ambulatory peritoneal dialysis (CAPD) in two cases, hemodialysis with extracorporeal ultrafiltration method (ECUM + HD) in one case and hemodiafiltration with continuous veno-venous hemofiltration (CVVHF + HDF) in one case for perioperative management. In each cases, intermittent HD was undergone during 4 days before operation. Intraoperatively, HD was used together with extracorporeal circulation. Blood pressure in the postoperative course changed more frequently in CAPD cases than ECUM + HD or CVVHF + HDF case. Especially, CVVHF + HDF stabilized the movement of circulation and kept balance of serum BUN, Cr after the operation (BUN; 27.2 +/- 6.3, Cr; 5.0 +/- 0.6). We concluded that CVVHF + HDF would be the most favorable method to maintain the fluid balance stably for the uremic patients after CABG.

Abstract
A successful operation on a 49-year-old female with aortitis syndrome associated with prosthetic aortic valve detachment was reported. Aortic valve replacement using SJM 25A had been performed for aortic regurgitation caused by aortitis. Though her C-reactive protein (CRP) was kept between (+/-) and (2+) with prednisolone administered, general fatigue suddenly appeared 4 years after the first operation. The blood sedimentation rate was 65 mm/30 min and CRP was (4+), and the echocardiography showed abnormal movement of the prosthetic valve with perivalvular leakage on admission. Aortography showed the valve detachment and abnormal movement due to enlargement of sinuses of Valsalva, one of which was transformed as a diverticulum and projected into Left ventricular cavity with moderate leakage. After the inflammation was well controlled, she was operated upon. Dilatation of sinuses, perforation of intima around the prosthetic valve were recognized as left ventricular-aortic discontinuity, but ascending aorta was not enlarged. So the prosthetic valve was suspended below coronary ostia with transmural mattress sutures from right atrium. Postoperative course was uneventful. The postoperative aortography revealed only trivial perivalvular leakage without abnormal movement of the valve. This was a rare case of the valve detachment in the aortitis patient.

Abstract
Bovine internal thoracic artery graft (BIOFLOW) was used for coronary artery bypass grafting (CABG). A 64-year-old woman who had undergone triple CABG with saphenous vein five years ago was referred to our hospital again with anginal attack. Coronary angiogram showed the obstruction of the graft for LAD and new stenosis at right coronary artery (RCA). Gastroepiploic artery was not available because the patient had a history of gastric ulcer several times, and saphenous vein had harvested initial operation. We planned re-CABG for LAD with left internal thoracic artery and RCA with BIOFLOW. But at the operation, LAD was not graftable because of severe calcification. So that we performed single CABG to RCA with BIOFLOW. The BIOFLOW was patent at the 28 th postoperative day. From our experience, BIOFLOW can be expected as a graft for CABG when saphenous vein, internal thoracic artery and gastroepiploic artery are not available.

Abstract
The patient was a 72-year-old female who was admitted with evaluation of dyspnea on effort. On cardiac catheterization, coronary angiography showed the fistula from both RCA and LAD to the pulmonary artery and L-R shunt ratio was 37.4%, and MR and TR were found. The preoperative examination showed renal dysfunction, BUN: 61.6 mg/ml, Cr: 21. mg/ml, 24 hr Ccr: 15.2 ml/min. At the operation, the fistula was closed from the inside of the pulmonary artery and MVR (27 SJM) and TAP (Kay-Reed method) were performed associated with the intra-operative hemodialysis. The peritoneal dialysis was used for 9 days after the operation. The hemodynamics and the urination were well controlled. A successful surgical repair of bilateral coronary artery-pulmonary artery fistula associated with valvular disease and severe renal dysfunction was reported.

Abstract
Surgical treatment of the dissection involving the ascending aorta or aortic arch represents one of the most complicated technical challenges. Recently continuous retrograde cerebral perfusion (CRCP) is sometimes applied in order to avoid cerebral complications. We compared two surgical groups, one of which was performed graft-replacement of ascending aorta using CRCP and another was utilized normograde cerebral circulation, about the technique of operation, total extracorporeal circulation (ECC) time, aortic clamp time, separate ECC time, total bleeding volume, and urination during operation. In the group using CRCP, separate ECC time was 53 min (mean), and intraoperative bleeding volume was only 1,170 ml. Good urination was obtained during operation. Postoperative courses were uneventful, and consciousness was smoothly and soon recovered. The new method of separate ECC has some advantages over the previously described methods, particularly for avoidance of cerebral complications. As it is not necessary to require dissecting, taping, and clamping of cephalic branches, operative procedure will be very simplified, easier and safer, leading to intraoperative bleeding is a fewer. It is our belief that this method should be widely applied in the operation of graft-replacement of ascending aorta or aortic arch in the near future.

Abstract
A 3-year-old boy had chronic repetitive atrial tachycardia. The tachycardia could not be induced neither terminated with rapid atrial pacing nor atrial extrastimuli. Overdrive suppression and warm-up phenomenon were demonstrated. These electrophysiological features suggested atrial ectopic automaticity. Endocardial and epicardial mapping determined the origin of tachycardia at the left atrial appendage. The LA appendage was excised and the tachycardia was completely terminated. The patient is asymptomatic without medication and echocardiographic indices of left ventricular function returned to normal over 1 year follow-up period.

Abstract
A dissecting aneurysm of the ascending and transverse aorta with heart failure due to sudden severe arotic valve insufficiency in a 47-year-old man has been treated successfully. Vasodilator therapy was done preoperatively, and then hemodynamics was improved markedly. A selective perfusion technique by using separate pumps at pre-determined flow-rates with hypothermia was utilized. The replacement of both the aortic valve and the ascending and transverse aorta involving brachiocephalic artery with a prosthetic valve and expanded polytetra-fluoroethylene coated woven Dacron grafts was performed.
