A 75-year old man presented with diuretic-resistant leg edema. He had a history of three cardiac surgeries: mitral valve plasty, mitral valve replacement with a stentless valve made of autologous pericardium, and mitral valve replacement with a mechanical prosthesis. Six years had passed since his last cardiac surgery. The tests revealed right heart failure due to a chronic expanding intrapericardial hematoma. The hematoma was removed via left thoracotomy, and which had been covered with the ePTFE pericardial membrane used in the previous chest closure was removed via left thoracotomy. The chronic expanding intrapericardial hematoma is a rare condition, and it was suggested that extensive coverage with the sheet may have been a contributing factor to its formation.

Physical performance measures, such as gait speed, one-legged stance and hand-grip strength, are known as assessment measures of motor function and predictors for adverse health outcomes, and widely used for assessing motor function in preventive programs for long-term care or screening of frail elderly. However, there is no standard assessment sheet for feedback of the results. In the present study, an assessment sheet on physical performance measures for community-dwelling older adults was developed. A pooled analysis of data from six cohort studies, including urban and rural areas was conducted as part of the Tokyo Metropolitan Institute of Gerontology Longitudinal Interdisciplinary Study on Aging. The pooled analysis included cross-sectional data from 4683 nondisabled, community-dwelling adults aged 65 years or older. Quintiles were derived according to age and sex group for six physical performance measures, i.e., hand-grip strength, one-legged stance, and gait speed and step length at both usual and maximum paces. The assessment sheets, which indicated the physical performance level according to age and sex, were developed by fitting third order polynomial curves to the data. The reference values in the present assessment sheet were considered to be derived from better represented community-dwelling older adults by using more large-scale population-based cohort data than that in the previous study. The assessment sheet should be useful for feeding back results on physical performance measures to elderly individuals and help them better understand their own physical performance levels.

This study was designed to evaluate the late changes of coronary bypass grafts in 60 patients who had undergone coronary bypass surgery and postoperative angiography in the period from 1994 to 1999. Angiography was performed at mean intervals of 84 months and a total of 134 grafts and 162 anastomoses were visualized. The Left internal thoracic artery and saphenous vein had a patency of 85% and 82%, there was not statistically significant. In this series, late graft function did not relate to the site of implantation, that was mainly due to excellent results of saphenous vein grafts. With increasing proximal stenosis severity (under 75% versus over 90%), there was an increase in patency rates and this relationship was statistically significant (p=0.0005). That was why about 20% of the grafts to moderately stenotic target vessels had occluded within 1 month after surgery. Ten patients among these 60 had cardiac symptoms, 6 were due to graft failure and the other 4 were due to new lesions in the right coronary artery. In the other 12 patients new coronary artery lesions without cardiac symptoms had been detected. Periodic coronary examinations should be recommended for the patients after surgery, regardless of the absence of symptoms.
