There were multiple factors predicting the risk of SCI after the FET technique. Paraplegia may be prevented by avoiding deep insertion of the stent graft and by keeping blood pressure elevated after the operation.
We demonstrate 50-Gb/s direct modulation by using 1.3-μm distributed-feedback lasers with a ridge waveguide structure. We employed InGaAlAs material for a multiple-quantum well to obtain a low damping factor K, and fabricated a ridge waveguide structure buried in benzocyclobutene to realize a structure with a low parasitic capacitance. In addition, to obtain high maximum frequency relaxation oscillations fr, we designed the cavity length L), and achieved a 3-dB-down frequency bandwidth of 34 GHz. We realized 50-Gb/s clear eye openings with a back-toback configuration, and achieved a mean output power of over 5.0 dBm, and a dynamic extinction ratio of 4.5 dB. We measured the 50-Gb/s transmission characteristics, and obtained clear eye openings for transmissions over 20-, 40-, and 60-km single-mode fibers (SMF). We also measured the bit-error-rate performance, and obtained an error-free operation and a power penalty of less than 0.5 dB after a 10-km SMF transmission.
Circulation Journal Official Journal of the Japanese Circulation Society http://www. j-circ.or.jp and postoperative complications and requirements, have been evaluated as predictors of POAF; however, most of these predictors were not consistent among studies and only advanced age was a consistent predictor. 6 Recently, echocardiographic assessments have achieved much better prediction of POAF by measuring the left atrium-related values including the left atrial volume index (LAVI), LA strain and total atrial conduction time (TACT). Although there are several measurements of TACT, the time interval from the P-wave onset on the electrocardiogram (ECG) to the peak of the A' lateral wave on TDI (PA-TDI duration) provides a reliable estimation of TACT, and the PA-TDI duration has been shown to be significantly related to new-onset AF. 7,8 Our previous study revealed that the PA-TDI duration was predictive of AF in patients undergoing off-pump coronary artery bypass grafting (CABG). 9 trial fibrillation (AF) is a common complication after cardiac surgery, occurring in 10-65% of the patients. 1 Several studies have found adverse outcomes associated with postoperative AF (POAF), including increased risk of hospital stay, higher risk of stroke, permanent pacemaker implantation, and increased in-hospital and long-term mortality rates. 2 The incidence of POAF is higher with valvular surgery. 3 Obviously, in aortic valve (AV) surgery, the incidence of AF is related to these postoperative complications. 4 Moreover, Filardo et al reported that new-onset POAF was significantly associated with increased long-term risk of mortality in patients undergoing AV replacement (AVR) surgery. 5 These results indicate that POAF should be prevented and controlled postoperatively.In the past 2 decades, many clinical variables, including preoperative characteristics, comorbidities, intraoperative findings A
The cryo-maze procedure was rather effective for eliminating chronic AF associated with both mitral and tricuspid valve disease, but there were a few cases with new atrial tachycardia. The box pulmonary vein isolation was useful in solitary mitral valve cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
