A 52-year old woman was referred to our hospital because of abdominal pain and restlessness. A chest contrast-enhanced CT showed huge pericardial effusion and intraluminal defects in the main pulmonary artery. We could not make a diagnosis based on the cytology of the pericardial effusion and histopathology of the mass with a sample taken by a catheter. Therefore, we undertook biopsies of the mass by median sternotomy, which led to the diagnosis of pulmonary intimal sarcoma. The tumor resection was performed to release the right ventricular outflow stenosis. We tried to resect the tumor as much as possible, and reconstructed the pulmonary artery and aortic root. She was discharged to home and survived 5 months after surgery.

Background : Connective tissue disease (CTD) is an idiopathic autoimmune disorder which causes systemic chronic inflammation. Inflammation causes various cardiovascular diseases. Systemic steroid use, which is usually the sole treatment for CTD, also causes arteriosclerosis. Although cardiovascular surgery is often necessary in patients with CTD, preexisting multiple organ dysfunction related to CTD, in addition to systemic administration of steroids or other immunosuppressants, is thought to increase the risk of surgery. However, little is known about how the disease process of CTD influences early and late cardiovascular surgery outcomes. Methods : To better understand these issues, we reviewed 31 patients with CTD (study group) and compared their outcomes to those of other patients (control group) who underwent cardiovascular surgery at our institution between April 2008 and November 2013. Results : There were 26 women and 5 men, and the average age was 64.4±16.7 years. CTD types included rheumatoid arthritis in 7 patients, systemic lupus erhythematosus in 6, aortitis syndrome in 6, polymyalgia rheumatica in 3, scleroderma in 3, polymyositis in 3, and others. The procedures included 10 valve cases, 10 coronary artery bypass grafting (CABG) or CABG-valve combination cases, and 11 isolated or complicated thoracic aortic surgery cases. Prior to undergoing these procedures, 24 patients (77.4%) were treated with steroids and/or immunosuppressant, and 6 patients had been diagnosed with interstitial pneumonia in the study group. Moreover, the rate of peripheral artery disease and carotid artery stenosis in the study group was significantly higher than that in the control group. There were no perioperative deaths in the study group. There were no significant differences in terms of major complications such as ischemic events, infection, acute kidney injury, lung injury, and others between the groups. We conducted a follow-up survey for the study group with an average period of 27.8±16.0 months. During the follow-up period, there were 4 late deaths. In addition, 8 patients required readmission, 6 for cardiovascular events and 2 for poor wound healing. All the survivors in the study group showed improved cardiac function and were in the NYHA functional class I and II. Conclusion : Cardiovascular surgery for patients with CTD can provide acceptable early and mid-term results.

Total anomalous pulmonary venous connection (TAPVC) is rarely associated with remarkably small left heart structures. In these types of cases, the hemodynamics resembles that of hypoplastic left heart syndrome, and the treatment strategy is controversial. We present the case of a 1-day-old girl with infracardiac TAPVC, small left heart structures (hypoplastic left heart complex), bilateral superior vena cava, and aberrant origin of the right subclavian artery. We performed a semi-emergent first-stage open palliation for repair of TAPVC, because of pulmonary venous obstruction. We concomitantly performed atrial septal defect (ASD) enlargement and bilateral pulmonary artery banding (BPAB). The postoperative course was uneventful and the left heart structures did not grow, so we performed the Norwood procedure and placed a right ventricle-pulmonary artery shunt with a 5.0 mm artificial graft. Subsequently, the left heart structures were not suitable for biventricular repair, so we chose univentricular repair. The patient underwent a bilateral bidirectional Glenn operation and Fontan completion at 6 and 23 months of age, respectively. TAPVC repair, BPAB, and ASD enlargement are reasonable surgical options for a patient with borderline small left heart structures and TAPVC, as they enable us to wait for growth in the left heart structures and to determine whether univentricular or biventricular repair is suitable.

Objective : The aim of this study is to describe a series of patients undergoing reoperation due to hemolytic anemia after mitral valve surgery and assess the mechanisms and surgical outcomes. Methods : Between 2009 and 2014, we performed redo mitral valve surgery in 11 patients who had refractory hemolytic anemia after mitral valve surgery at Kyoto University Hospital. The mean age of the patients was 72.2±6.8 years old, and there were 5 men. Results : Preoperative echocardiography demonstrated that only 3 patients had ≥ grade 3 mitral regurgitation (MR), the rest of the patients had only mild to moderate MR. The mechanisms of severe hemolysis included paravalvular leakage (PVL) after mitral valve replacement (MVR) in 8 patients, structural valve deterioration (SVD) after MVR using a bioprosthesis in one, and residual/recurrent mitral regurgitation after mitral valve plasty (MVP) in two. All the patients except one (re-MVP) underwent MVR. The mean interval between previous operation and current operation was 14.1±9.4 years in post-MVR cases, and 2.0±1.9 years in post-MVP cases. There were three late deaths, one of which was due to cardiac death (exacerbation of heart failure due to pneumonia). There was one patient who required re-MVR for recurrent hemolysis due to PVL after MVR. Conclusion : Although hemolytic anemia after mitral valve surgery is rare, it often requires reoperation regardless of the degree of MR at late follow-up period. Thus, patients after mitral valve surgery should be carefully followed-up.

We report a case of 76 year-old woman who had previously undergone coronary artery bypass grafting (CABG) with the right internal thoracic artery (RITA) bypassed to the left anterior descending artery. Six years after CABG, she developed acute type A aortic dissection, and she was medically treated because the false lumen was thrombosed and it was considered that surgical intervention would be high risk for the patent RITA graft crossing between the sternum and the ascending aorta. During follow-up, her aortic aneurysm enlarged to 57 mm in diameter, and finally she was referred to our hospital for surgical intervention. In this case, preservation of the patent RITA graft was thought to be critical because the RITA graft was the only blood source for the left anterior descending artery. Prior to re-median sternotomy, we performed a right anterior minithoracotomy to make sufficient space between the sternum and the RITA graft, and then instituted peripheral cardiopulmonary bypass to decompress the heart. After re-sternotomy, we ensured minimum dissection of the RITA graft, and we successfully accomplished graft replacement of the ascending aorta to the aortic arch without injuring the patent RITA graft. In cases with a patent RITA graft and an ascending aortic aneurysm close to the sternum, our strategy is considered to be efficient for re-median sternotomy.

Borderline personality disorder (BPD) is often manifested by maladaptive behaviours such as self-injury. The interpersonal style characteristic of BPD makes
it difficult to maintain stable therapeutic relationships, with the patient often discontinuing treatment. Although dialectical behavior therapy (DBT) has been
reported to benefit patients with BPD, reports in Asian countries have been few. We herein describe a 22-year-old female with BPD and a history of attempted suicide
and self-injury who underwent DBT at our hospital. Methods: Our 6-month DBT consists of 4 parts: weekly psychotherapy by a psychiatrist, weekly skills training by
a clinical psychologist and nurse, emergency consultations, and supervision/consultation meetings. Individual psychotherapy and skills training
sessions, respectively, were conducted for this patient 24 times. Results: After completing DBT, the number of self-injuries and frequency of suicidal ideation in
our patient decreased. Conclusion: Although more costly than standard treatment for BPD, a trial of DBT might be worthwhile in Japanese patients.

A 60-year-old man was admitted to our institution with abnormal ECG findings. Coronary CT and angiography showed coronary aneurysms from the left main trunk to the bifurcation of the left anterior descending artery, and the left circumflex artery, with severe stenosis and complete obstruction of the proximal right coronary artery. Morphological evaluation findings strongly suggested that the coronary aneurysms were highly related to childhood Kawasaki disease. We successfully performed triple vessel coronary artery bypass grafting. Here, we report a very rare case of coronary aneurysms presumed to be due to childhood Kawasaki disease in an elderly man.

A 11-year-old boy was admitted to our hospital with a diagnosis of the progressive residual coarctation of the aorta, severe left ventricular hypertrophy and dilatation of the ascending aorta. He had previously undergone 3 operations for coarctation of the aorta. We performed ascending-to-descending aortic bypass through a median sternotomy for residual coarctation of the aorta. Partial cardiopulmonary bypass (CPB) was established via the right femoral artery and right atrium. A cephalad retraction of the heart with a heart positioner and a longitudinal pericardial incision over the descending aorta allowed excellent exposure of the aorta through the posterior pericardium. The graft was anastomosed to the ascending aorta and descending aorta. The graft was brought around the right lateral aspect of the right atrium and through to the anterior aspect of right pulmonary veins and inferior vena cava. The bypass graft size was 14 mm in diameter. The CPB time was 134 min, and operation time was 232 min. The postoperative course was uneventful, and he did not suffer from paraplegia. His blood pressure postoperatively normalized without medication. He was discharged 20 days after surgery. The ascending-descending aortic bypass through a posterior pericardium approach is a safe and effective option for relieving residual coarctation and improving hypertension, for patients who have complex coarctation requiring surgical correction. However, because of his young age (II) it is necessary to follow him up carefully.

We reviewed 223 cases of isolated coronary artery bypass grafting (CABG) during the past 6 years, and used the EuroSCORE to assess the differences in clinical outcomes between off-pump CABG (OPCAB) and on-pump CABG (conventional CABG: CCABG). After March 2000, our first choice has been OPCAB, with CCABG selected only for cases with unstable hemodynamics. The total of 223 isolated CABG cases consisted of 129 OPCAB and 94 CCABG, but after March 2000, 94 OPCAB and 42 CCABG were performed. Mean EusoSCORE was 5.8 for OPCAB and 4.1 for CCABG, and corresponding expected survival rates were 7.20% and 5.04%. The 3 cases of hospital death (mortality, 1.3%) all belonged to the earlier CCABG groups and were not related to cardiac death. After March 2000, no hospital deaths occurred in either group. Midterm results showed 5 deaths, but these were not related to cardiac death, either. There were no significant differences between the 2 groups in terms of hospital complications other than long mechanical ventilation time, which was markedly longer only for the OPCAB groups (p<0.01). Mean number of grafts was significantly high for patients in the CCABG groups (OPCAB 2.1 vs. CCABG 2.8; p<0.05). We have therefore been using OPCAB for high-risk cases, and midterm results of our CABG patients were satisfactory.

Objective : Carvedilol is a non-selective β blocker with an α blocking activity. Since this drug is highly fat-soluble, it can pass through the blood-brain barrier, and thus may induce depression and lower QOL. In the present study, physicians and pharmacists collaborated to evaluate the antihypertension effect of carvedilol and post-administration changes in QOL. Furthermore, the relationship between QOL and antihypertension effect was analyzed.
Design : Self-controlled study.
Patients and Methods : Subjects were outpatients with hypertension above the age of 70 years who visited one of 42 medical institutions in Japan between April 1995 and March 1996. A total of 243 patients were registered, and 10-20 mg of carvedilol was administered once a day for six months. Pharmacists assessed the QOL of these patients by asking 82 questions on three separate occasions : before administration and one and six months after administration. The antihypertensive effect of this drug was investigated in patients in whom all three QOL questionnaires were collected. The main test items were antihypertensive effect, changes in QOL (subjective QOL with a special emphasis on patient psychology), and the relationship between antihypertensive effect and QOL. The antihypertensive effect of this drug was statistically analyzed by a paired t-test, and changes in QOL were statistically analyzed using generalized estimating equations.
Results : All three QOL questionnaires were collected from a total of 146 patients. Their pre-administration systolic blood pressure was 159.6±1.4 mmHg, and diastolic blood pressure 94.0±0.9 mmHg, and their blood pressure decreased significantly one month after the start of administration. This antihypertensive effect of carvedilol persisted, and the systolic and diastolic blood pressure of these patients six months after the start of administration was 141.1±1.2 and 85.2±0.7 mmHg, respectively (significant decreases when compared to pre-administration levels ; both p<0.05).
Subjective QOL improved significantly after carvedilol administration. And, changes were not seen in sexual function. Changes in the five categories of subjective QOL were as follows : psychological stability, disease-induced inconvenience, and independence improved significantly after carvedilol administration, but changes were not seen in gratification or vitality. However, improvements in subjective QOL did not correlate with improvements in blood pressure.
Conclusions : The results of the present study showed that carvedilol improved QOL without negatively affecting sexual function. Subjective QOL reflects the psychological well-being of patients. In the present study, psychological stability, disease-induced inconvenience, and independence improved significantly, but changes were not seen in gratification or vitality. Since β blockers can suppress the central nervous system, they can reduce psychological stability, gratification and vitality. Even though carvedilol is highly fat-soluble, the results of non-clinical studies have shown that it does not suppress the central nervous system as much as propranolol. The results of the present study showed that carvedilol does not strongly suppress the central nervous system of humans. Moreover, significant changes in QOL were not seen between one and six months after the start of administration of carvedilol, suggesting that it is possible to estimate the QOL of patients on antihypertensive therapy after six months of administration by assessing their QOL one month after administration.
