OBJECTIVES Deep sternal wound infection (DSWI), especially in patients with diabetes mellitus (DM), is a major concern after coronary artery bypass grafting (CABG) with bilateral internal mammary artery (BIMA) grafts. We evaluated the risk of DSWI and other clinical outcomes between continuous insulin infusion therapy (CIT) and insulin sliding scale therapy(More)
OBJECTIVE As transcatheter aortic valve implantation (TAVI) may become a potential treatment for high-risk patients with aortic stenosis (AS), evaluation of outcomes after open aortic valve replacement (AVR) in elderly patients is warranted. We documented early and late outcomes after isolated AVR in octogenarians compared with younger age groups. METHODS(More)
Objectives To identify factors that determine early saphenous vein graft failure (VGF) within 1 month after coronary artery bypass grafting (CABG). Methods Seven hundred forty-nine consecutive patients underwent primary isolated CABG with saphenous vein grafts at three Japanese centres from 1 January 2005 to 31 December 2014. According to angiographic(More)
OBJECTIVES Patients with diabetes mellitus often have more complicated postoperative courses and worse outcomes after coronary artery bypass grafting than those without this condition. Dipeptidyl-peptidase-4 inhibitors are a new class of oral medication for treating type 2 diabetes mellitus. We investigated how these drugs influence the postoperative course(More)
OBJECTIVES This study sought to investigate the clinical utility of aortic valve calcium score (AVCS) determined by using cardiac multislice computed tomography (MSCT). METHODS Data of 1315 consecutive patients who underwent both conventional echocardiography and MSCT were reviewed. Degree of aortic stenosis (AS) was assessed according to mean pressure(More)
Mobile abnormal structures in the aortic valve are difficult to diagnose in some cases. We describe a rare clinical case of fibrous strand rupture in a dialysis patient, which was surgically treated. Preoperative echocardiography showed a mobile structure attached to the noncoronary cusp, and intraoperative findings revealed rupture of the fibrous strand in(More)
