We report a rare case of primary cardiac lymphoma in the right atrium. An 85-year-old woman with severe heart failure was referred to our hospital. The echocardiography revealed a huge tumor occupying the right atrial cavity. We conducted an emergency operation to resect the tumor. However, as the tumor strongly adhered to the wall of the right atrium and tricuspid valve, we performed partial resection of the tumor to improve hemodynamics. The pathological examination of the tumor was consistent with malignant lymphoma of B-cell origin. Although the postoperative chemotherapy was effective to reduce a volume of the tumor, the patient died because of the adverse reaction to medication.

Treating a thoracic aortic aneurysm (TAA) after coronary artery bypass graft (CABG) surgery requires an appropriate surgical procedure to preserve the functional graft. We present a case of hybrid procedure of thoracic endovascular aortic repair combined with a redo off-pump CABG via median sternotomy. The patient was a 76-year-old man with a history of CABG and abdominal aortic replacement in a different country. Chest computed tomography revealed a saccular-shaped aortic aneurysm in the distal aortic arch with diameter of 5.6 cm. Coronary angiography revealed theLIMA graft was patent but anastomosed to the diagonal branch and the left anterior descending artery (LAD) was totally occluded and was opacified through the right coronary artery. Significant ischemic change in the anteroseptal wall suggested a requirement of surgical revascularization of LAD. The chest was opened via re-midsternotomy. Then the 3 arch vessels were reconstructed with a trifurcated artificial graft attached to the ascending aorta and coronary artery bypass grafting was performed on the beating heart. Finally, the aneurysm was excluded by introducing a stent graft through the graft to zone 0. The patient's postoperative course was uneventful and he was discharged on postoperative day 16. A hybrid procedure via median sternotomy was useful in the surgery for TAA with the functional LIMA after CABG.

We studied 73 patients, 70 years of age or older, who underwent aortic valve replacement for aortic stenosis between October, 1990 and October, 2004. There were 31 men and 42 women with a mean age of 75.7±3.6 years. Mechanical valves were implanted in 37 patients, and bioprostheses in 36 patients. Operative mortality was 1 of 73 (1.4%) and the New York Heart Association functional class improved to class I or class II in all of the hospital survivors. Follow-up (100%) extended from 0.3 to 11.6 years (mean 3.7 years). There were 16 late deaths (5.9% per patient-year), including valve-related deaths in 6 patients. The overall survival rates at 5 and 10 years was 74.2% and 44.3%, respectively. The freedom from valve-related events at 5 and 10 years was 78.8% and 78.8%, respectively. The 10-year survival rates and freedom from valve-related events were not different between the patients with mechanical valves and those with bioprostheses. The size of the implanted valve did not influence the late survival or freedom from valve-related events. The outcome after aortic valve replacement in the elderly (70 years and older) was excellent with low operative mortality, and acceptable late mortality and morbidity. Thus, aortic valve replacement for elderly patients should have the same indications as for younger patients. Bioprostheses showed good long-term results with no structural valve deterioration, thromboembolism, or bleeding events. Mechanical valves, which required the maintenance of an anticoagulant therapy, were also useful with acceptable late morbidity. The long-term results with small valves (≤19mm) were comparable to the results with large valves (>19mm) in the elderly. Thus, the use of these small valves in this particular age group seems to be acceptable.

This cross-sectional study examines the association between coping with past ankle sprain, and current physical activity levels and sedentary times. It included a total of 1,464 male soccer players, who participated in the 6th Senior Soccer Festival in Shizuoka in 2017. A self-administered questionnaire was conducted on the day of the festival and 567 subjects responded (38.7% response rate). Participants answered questions regarding the coping with past ankle sprain, such as whether they had first aid treatment (yes/no), the type of initial treatment facilities (6 categories), and their most frequented facilities (5 categories). Additionally, the International Physical Activity Questionnaire Short Form was used to obtain information on current physical activity level and sedentary time. We compared the mean values of physical activity levels and sedentary times with the first aid treatment, initial treatment facilities and most frequented facilities answers, respectively. The mean age was 64.7 years. Physical activity level was associated with first aid treatment (yes: 3860.3 Metabolic equivalents (METs)/min/week; no: 3082.0 METs/min/week) (p=0.033). Sedentary time was also associated with first aid treatment (yes: 265.4 min/day; no: 321.3 min/day) (p=0.014). Initial treatment facilities and most frequented facilities were not associated with physical activity levels or sedentary times. Our study showed that those who had received first aid treatment had high physical activity levels and low sedentary time.
