Cell-based angiogenesis is a promising treatment for ischemic diseases; however, the survival of implanted cells is impaired by oxidative stress in the ischemic microenvironment. We tested the hypothesis that hypoxic preconditioning of implanted cells enhances their resistance against oxidative stress, increasing cell survival and angiogenic potency after(More)
BACKGROUND Therapeutic angiogenesis induced by the implantation of autologous bone marrow-derived cells has been used for the treatment of ischemic diseases. However, as the outcomes of cell implantation obviously vary among patients, it is essential to identify patients that would benefit the most from this treatment. METHODS AND RESULTS We collected(More)
BACKGROUND Deep sternal wound infection after cardiac surgery carries high morbidity and mortality. Our strategy for deep sternal wound infection is aggressive strenal debridement followed by vacuum-assisted closure (VAC) therapy and omental-muscle flap reconstrucion. We describe this strategy and examine the outcome and long-term quality of life (QOL) it(More)
A 58-year-old Japanese female was referred to our hospital. Although the electrocardiogram showed ST elevation, coronary angiography showed intact coronary artery. We diagnosed Takotsubo cardiomyopathy and a left ventricular thrombus. Anticoagulation was administered; however, the left ventricular thrombus had become mobile and protrusive. We extirpated the(More)
OBJECTIVE The right gastroepiploic artery (RGEA) is widely used as an in situ arterial graft for coronary artery bypass grafting (CABG); however, it is impossible to measure an RGEA or check for calcification or stenosis and assess its suitability as a graft before angiography or harvest. We evaluated the accuracy of preoperative three-dimensional computed(More)
