OBJECTIVE To determine the prevalence, hemodynamic characteristics, and risk factors for low systemic vascular resistance (SVR) state following after off-pump coronary artery bypass (OPCAB). PATIENTS AND METHODS SVR data could be obtained for 116 OPCAB patients. Low SVR was defined as an indexed systemic vascular resistance (SVRi) of <1,800 dyne x s/cm(5)(More)
The optical properties, Faraday effect and Verdet constant of ceramic terbium gallium garnet (TGG) have been measured at 1064 nm, and were found to be similar to those of single crystal TGG at room temperature. Observed optical characteristics, laser induced bulk-damage threshold and optical scattering properties of ceramic TGG were compared with those of(More)
BACKGROUND It remains controversial whether right internal thoracic artery (RITA) to left anterior descending artery (LAD) bypass has qualitative limitations which cannot be evaluated based on the patency rate alone. METHODS The 111 subjects underwent graft angiography after bypass grafting of the left or right internal thoracic artery (ITA) to the LAD.(More)
BACKGROUND AND AIM OF THE STUDY Skeletonization of the internal thoracic artery (ITA) has several advantages: sequential bypass grafting can be easily performed, and a graft of increased length can make the distal coronary artery accessible. However, kinking of the grafts has been observed on postoperative angiograms in a few cases. We investigated whether(More)
An ultraintense laser injected a 10 J of power at 1.053 microm in 0.5 ps into a glass capillary of 1 cm long and 60 microm in diameter and accelerated plasma electrons to 100 MeV. One- and two-dimensional particle codes describe wakefields with 10 GV/m gradient excited behind the laser pulse, which are guided by a plasma density channel far beyond the(More)
We have achieved a high compression ratio by stimulated Brillouin scattering (SBS) consisting of two long cells. A 13-ns Nd:YAG laser pulse was temporally compressed to about 160-ps phase-conjugated pulse in heavy fluorocarbon FC-40 liquid at a 1064 nm wavelength. The maximum reflectivity of SBS process was over 80 % without an optical damage. The(More)
INTRODUCTION The material growth capability of YAG has been improved using ceramics technology in 1990s [1]. Recently, the large YAG ceramics of 10cm×10cm×2cm dimensions was applied for laser oscillation [2]. In the large YAG ceramics, the parasitic oscillation would be the critical issue because it causes the limitation of small-signal gain and stored(More)
Mycotic aneurysm of the aorta is a rare, but life-threatening pathology. In recent years, endovascular stent graft placement has been introduced as an effective alternative for treating infected aortic aneurysms. A 64-year-old woman with a history of paraplegia due to spinal cord injury was referred to our institute with fever and blood-tinged sputum.(More)
