We report a case of mitral active infectious endocarditis in a 15-year-old boy successfully managed by folding plasty without any prosthetic devices. He was admitted to our hospital because of high fever and general fatigue. Echocardiography revealed a vegetation of 15×18 mm attached to the anterior commissure area of the mitral valve with severe mitral regurgitation. Brain MRI showed acute brain infarction without symptoms, and enhanced computed tomography also showed multiple infarctions of the spleen and the left kidney. Staphylococcus aureus was identified in the venous blood culture. We diagnosed active mitral infectious endocarditis with multiple systemic embolization and disseminated intravascular coagulation. After antibiotic therapy for 9 days, mitral valve surgery was performed with cardiopulmonary bypass and cold blood cardioplegia through a median sternotomy and a left atriotomy. A giant vegetation was attached to the damaged mitral leaflet of the AC to A1 and P1. The vegetation and damaged leaflet were removed by an ultrasonic aspirator and resected. Removal of the superficial vegetation with the aspiration method enabled preservation of more than half of the A1 and half of the P1 for valve repair. The anterior commissure annulus without a leaflet was reconstructed by compression suture. Furthermore, in a procedure similar to folding plasty, leaflet A1 was folded down and sutured to annulus P1, and a simple suture technique was involved to the left cut edges of leaflet A1 and P1. The postoperative course was uneventful. Two years after surgery, the patient was well with no recurrence of infection and trivial mitral regurgitation on echocardiography.

This study aims to examine the effects of kinesio taping (KT) on explosive muscle and sustained maximal muscle exertions of lower limbs in pre- and post-strenuous exercises (SE) up to exhaustion. Twenty healthy college males (mean age 20.4 ± 1.08 yr) participated in the experiment for both the conditions of strapping KT (KT group) and no strapping KT (control group) . They all took pre- and post-SE isokinetic tests (IK test) .
The KT was strapped around muscle groups related to flexion and extension motions of a knee joint before the experiment. The effects of KT were confirmed on the exertion of the explosive muscle strength in flexion motion of post-SE, and the sustained muscle strength in pre- and post-SEs. It was inferred that the effects of KT relate to the fatigue state of muscle groups related to motion and motion types, and interpretation of these effects differs by the load intensity and the variables used for evaluation.
