..In conclusion, the Gelseal™ graft used in the ascending aorta demonstrates a small but continuous increase in the diameter, up to 5 years after implantation, without any adverse events...

..We tried to identify the predictors for short-term and long-term outcomes after CABG, which have not been well studied...

..In patients with acute type A aortic dissection (AAD), localization of the primary entry tear to be excluded is of major importance for intervention...

..In this unusual case, the metastatic lesions were the 1st clinical manifestations of a malignant cardiac tumor...

..The outflow suture line dehiscence caused blood flow into the cavity, porcine aortic wall rupture, and leaflet destruction...

..We investigated the blood supply of the chest wall noninvasively using near-infrared spectroscopy (NIRS) immediately after CABG...

..We investigated hemodynamic effects of intra-aortic balloon pumping (IABP) in in-situ and aorta-coronary (A-C) grafts during coronary artery bypass grafting (CABG)...

..We describe a technique of meticulous crossclamping of a difficult aorta during short-term moderate hypothermic circulatory arrest...

..We investigated flow characteristics of right gastroepiploic arterial grafts, widely used to extend in situ arterial conduits in coronary artery bypass grafting...

..The mortality and morbidity rates are high after cardiac surgery in hemodialysis (HD)-dependent patients. To improve their outcomes, optimal perioperative managements should be discussed...

..Coronary artery bypass grafting (CABG) is best indicated for chronic total occlusion of the left anterior descending artery (LAD) with collaterals. We investigated angiographic changes in the collateral circulation after CABG...

..However, the efficacy of DES for dialysis patients still remains controversial. This study compares the early and long-term clinical outcomes of coronary artery bypass grafting (CABG) and PCI with DES in dialysis patients...

..Respiratory management with bilevel positive airway pressure was thus found to be quite useful for patients with neuromuscular disease...

..This study reports our experiences and evaluates whether dialysis patients can be treated in a way that is similar to nondialysis patients...

..We examined the hypothesis that complete skeletonization of an internal thoracic artery (ITA) results in increased diameter of the graft for anastomosis and therefore improves graft flow in coronary artery bypass grafting...

..The hypothesis of the present study was that the presence of diabetes mellitus (DM) affects the improvement in SAECG after CABG...

..Pericardiectomy and removal of the calcification were performed safely using an ultrasonic scalpel, without cardiopulmonary bypass, resulting in hemodynamic improvement and relief of his symptoms...

....

..Unfortunately, even after PAD, allogenic blood transfusion is not always avoided. We investigated the predictors of blood component usage during elective cardiac surgery in patients prepared with PAD...

..However, there are no established methods for risk stratification of the patients with liver cirrhosis (LC) regarding cardiac surgery. We present our experience of preoperative evaluation of liver function using asialoscintigraphy...

..However, this improving effect was variable and closely related to the presence of prior myocardial infarction and the completeness of revascularization...

..Both La and %La-v, as an initial value in the intensive care unit, may play an important role in planning the postoperative management of patients undergoing open-heart surgery...

..The patient recovered uneventfully and MTX was resumed one week after surgery. Since MTX has been recently approval for treatment of RA in Japan, Japanese surgeons should pay attention to the appropriate perioperative use of this drug...
