ABSTRACT
A 28-year-old man visited the emergency department of our hospital with a chief complaint of palpitation and chest pain. The patient had undergone 4 operations at other hospitals for tetralogy of Fallot (TOF), left pulmonary atresia, an aberrant right coronary artery, and a right aortic arch. As a result of thorough investigations, we suspected that the cause of the patient's symptoms was an excess of the right ventricular pressure over the left ventricular pressure, which was caused by right ventricular compression resulted from an abnormal mass on the anterior surface of the right ventricle, and by pulmonary stenosis (PS) associated with right ventricular outflow tract stenosis (RVOTS). Excision of the mass, right ventricular outflow restoration (RVOTR), and pulmonary valve replacement (PVR) were indicated. The mass on the anterior surface of the right ventricular was found to have been caused by retention of serous fluid in the interstice formed by a folded expanded polytetrafluoroethylene (ePTFE) pericardial sheet. An ePTFE pericardial sheet, which is used to supplement the pericardium, has been reported to have advantages with respect to prevention of adhesion, denaturation of pericardial substitutes, and inflammatory thickening and adhesion of the epicardium, compared with other materials used as pericardial substitutes. However, epicardial thickening has been noted with the use of ePTFE pericardial sheets, and hence, its use is currently avoided in many cases. This case presents an extremely rare pathology in which the inflammatory reaction of the epicardium caused by an ePTFE pericardial sheet is suspected to have caused serous components to become tightly encapsulated in the interstice formed by the folded patch ; no definite cause was identified. Thus far, no other such case has been reported, and ePTFE pericardial sheets should be used with caution.
ABSTRACT
A 79-year-old woman had undergone mitral valve replacement (Omnicarbon (OC) valve : 31 mm) due to rheumatic mitral stenosis with regurgitation and tricuspid annuloplasty at the age of 54. The patient developed anemia and congestive heart failure with pleural effusion and an elevated LDH level in 25 years late up without any valve-related cardiac event. Echocardiography revealed perivalvular leakage near the anterolateral commissure. The patient received re-mitral valve replacement (CEP valve : 25 mm) and a tricuspid valve ring annuloplasty (MC<sup>3</sup> Tricuspid ring : 28 mm). The annulus was covered with marked calcification and fibrosis with a partial deficit at the anterior part of antero-lateral commissure. Despite the thorough pathological examination, we could not clarify the etiology of sudden onset of hemolysis.The patient was discharged uneventfully on the 28th day after operation. In general, the OC valve can work without serious complications for a long time. We report a rare case of perivalvular leakage 25 years after mitral valve replacement with hemolysis and congestive heart failure.
ABSTRACT
A 54-year-old woman with long-lasting pleural effusion developed abdominal distention due to ascites from bilateral ovarian tumors. The patient had undergone breast-conserving surgery and axillary lymph node dissection for left breast cancer in October 2000, and had developed left pleural effusion in July 2006. Cytological examination of the pleural effusion found no malignant cells. Thoracic drainage with intrathoracic administration of OK-432 (Picibanil) had failed to control the pleural effusion. Positron emission tomography taken at the abdominal distention showed bilateral ovarian tumors. After failure to control the ascites with systemic and intra-abdominal chemotherapy, bilateral oophorectomy resulted in normalization of elevated serum tumor-marker levels and the disappearance of both the ascites and pleural effusions (i.e., pseudo-Meigs' syndrome). Pathological examination showed the tumors to be estrogen receptor-positive metastatic ovarian tumors from her breast cancer. The patient remained well with no further recurrence for 40 months under aromatase inhibitor therapy.

Lambl's excrescences are the fibrous structures which are attached to the heart valve, and usually the presence of Lambl's excrescences alone is not an indication of operation. The operative indications of isolated Lambl's excrescence is still controversial, because some reports indicated cross relationship between Lambl's excrescences and cerebral embolism. Based on these facts, we discussed our 3 cases of Lambl's excrescences. Two of the cases had been complicated with severe mitral regurgitation and Lambl's excrescences were resected at the time of mitral valve plasty. In another case, Lambl's excrescence was found with echocardiography during chronic heart failure therapy. This patient had a past history of cerebral infarction, but no relationship of cerebral infarction was suggested. In this case, cardiac surgery was not required, so we followed isolated Lambl's excrescence without resection in this case. One operated case, which had infective endocarditis was suspected by echocardiography, had slighted inflammatory reaction but blood culture was negative. Diagnosis of Lambl's excrescence was made by histopathological examination. One report suggested that the cause of the cerebral infarction is not Lambl's excrescence itself but the thrombi around Lambl's excrescence. However, we hesitate to operate on isolated Lambl's excrescence. Based on some reports, it is useful to resect Lambl's excrescence when a concurrent cardiac operation is carried out to avoid cerebral embolic events.
ABSTRACT
Homologous blood transfusion may increase generalized inflammation by stimulating a patient's immune system during an open heart operation using cardiopulmonary bypass (CPB). We examined the beneficial effects on lung function of having no homologous blood transfusion during pediatric open heart operations. Thirty-three consecutive patients with ventricular septal defect were divided into (a) an autologous blood transfusion (AB) group (<i>n</i>=16) consisting of patients in whom predonation of autologous blood was undertaken and so homologous blood was not transfused, and (b) a control group (<i>n</i>=17) consisting of patients in whom homologous blood was used with a leukocyte removal filter during and after operation. Patients' age, sex, body weight, and contents of primed solution of the bypass circuit were similar in the 2 groups. Arterial blood gas analysis was carried out several times and the respiratory index (RI) calculated. Postoperative duration of intubation, white blood cell counts, and CRP titer were also compared. RI immediately after CPB did not differ between the AB and control groups, but RIs 3 and 6h after operation were significantly lower in the AB than in the control group (0.43±0.08 vs. 0.79±0.15 and 0.38±0.07 vs. 1.60±0.17). Duration of intubation, white blood cell counts, CRP titer were not statistically different. The results suggest that avoiding transfusion of whole homologous blood elements works effectively for preventing lung dysfunction after CPB.
ABSTRACT
A pseudoaneurysm of the ascending aorta is a complication found in aortic valve surgery. A 66-year-old man who had a previous history of aortic valve replacement due to infectious endocarditis was admitted to our hospital suffering from chest pain. Follow-up chest X-ray and transthoracic echocardiogram had revealed no findings of pseudoaneurysm during the intervening period. At admission, computed tomographic scan and transesophageal echocardiogram each showed a Type A acute aortic dissection and a pseudoaneurysm of the ascending aorta. Under cardiopulmonary bypass and deep hypothermic circulatory arrest, an ascending aortic graft replacement was carried out uneventfully. The patient is well 14 months postoperatively. Postoperative examinations following aortic surgery should be performed not only from the view point of cardiac function, but also from that of a pseudoaneurysm.
ABSTRACT
A case of combined redo off-pump CABG (OPCAB) with right gastroepiploic artery and abdominal aortic aneurysm repair is reported. A 71-year-old man with a previous history of CABG was admitted for the operation of recurrent angina pectoris and known abdominal aortic aneurysm. Preoperative coronary angiograms showed obstruction of LITA graft for LAD. The operative procedure consisted of redo OPCAB using right gastroepiploic artery as a transdiaphragmatic graft under left antero-lateral thoracotomy and graft replacement of abdominal aortic aneurysm under median laparotomy simultaneously. This strategy has the advantage of avoiding the continuity of median sternotomy and laparotomy and contributes to the minimally invasive procedure in the combined operation.
ABSTRACT
A 7-year-old boy suffered from isolated interruption of the aortic arch without any other complications or cardiovascular malformations. Cardiac murmur, which had been apparent since one month of age, had been left untreated because of the absence of any symptoms of heart failure. Isolated interruption of the aortic arch was noted during a routine physical examination at school and the patient was referred to our hospital for a complete medical evaluation. Blood-pressure difference was recognized not only between the right side and the left side of the upper extremities but also between the upper and lower extremities. On the basis of the results obtained via magnetic resonance angiography (MRA) and aortography, a definitive diagnosis of isolated interruption of the aortic arch was made. Reconstruction of the aortic arch by synthetic implant was indicated. The blood-pressure difference disappeared and the postoperative course was satisfactory.
