Abstract Purpose We investigated the differences between a sheathless guiding catheter and a Glidesheath slender/guiding catheter combination regarding access-site complications in percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). Methods We enrolled consecutive 1108 patients undergoing transradial primary PCI for ACS at our hospital using either a 7.5-Fr sheathless guiding catheter (Sheathless group) or a 7-Fr Glidesheath slender/7-Fr guiding catheter combination (Glidesheath group); 1:1 propensity score matching was performed, and 718 subjects (359 in each group) were included in the propensity-matched sample. Results Compared with the Sheathless group, the Glidesheath group had significantly less frequent ultrasound-diagnosed radial artery occlusion at 30 days (Sheathless: 4.7% vs. Glidesheath: 1.4%, p=0.015). No significant differences were observed in severe radial spasm (Sheathless: 1.4% vs. Glidesheath: 2.0%, p=0.77) or access-site bleeding (Sheathless: 9.8% vs. Glidesheath: 8.6%, p=0.70). Conclusion Thus, 7-Fr Glidesheath slender/7-Fr guiding catheter combination is clearly more advantageous than 7.5-Fr sheathless guiding catheters for decreased risk of radial artery occlusion in transradial PCI for ACS. “Sheathless” vs. “Glidesheath slender” Funding Acknowledgement Type of funding source: None

A Glidesheath slender (Terumo, Tokyo, Japan) and a sheathless Eaucath guiding catheter (Asahi Intecc, Nagoya, Japan) are two major slender devices utilized in percutaneous coronary intervention (PCI). This study aimed to investigate the differences in access-site complications between these devices in PCI for acute coronary syndrome (ACS). A total of 1108 consecutive patients who underwent transradial PCI for ACS were enrolled. Transradial PCI was performed using either a 7-Fr Glidesheath slender/7-Fr guiding catheter combination (Glidesheath group) or a 7.5-Fr sheathless guiding catheter (Sheathless group); 1 : 1 propensity score matching was performed, and 728 patients (364 in each group) were included in the propensity-matched population. In the matched patients, univariate analysis revealed that the Glidesheath group had less radial artery occlusion (RAO) at 30 days (Glidesheath: 1.4% vs. Sheathless: 4.1%, odds ratio (OR) = 0.33, 95% confidence interval (CI) =  0.12–0.91, p=0.039), whereas no significant between-group differences were observed in severe radial spasm (Glidesheath: 1.4% vs. Sheathless: 1.9%, OR = 0.71, 95% CI = 0.23–2.22, p=0.58) or access-site major bleeding (Glidesheath: 1.4% vs. Sheathless: 1.6%, OR = 0.83, 95% CI = 0.26–2.71, p=1.00). Multivariate analysis revealed that the choice for Glidesheath was significantly associated with less RAO (OR = 0.32, 95% CI = 0.11–0.93, p=0.036). In conclusion, 7-Fr Glidesheath slender/7-Fr guiding catheter combination is obviously more advantageous than 7.5-Fr sheathless guiding catheters for decreased risk of RAO. The potential low risk of RAO in our findings supports the adoption of the 7-Fr Glidesheath slender sheath/7-Fr guiding catheter combination in transradial PCI for ACS.

Guiding Catheter

Minimizing the catheter size can reduce vascular access complications and contrast dye usage in coronary angiography. The small diameter of the 4Fr guiding catheter has limited the use of several angioplasty devices such as intravascular ultrasound (IVUS) in the past. However, the combination of a novel IVUS catheter and a 0.010 guidewire makes it possible to perform IVUS-guided percutaneous coronary intervention (PCI) with a 4Fr guiding catheter. We herein report the case of a 51-year-old man with silent myocardial ischemia who underwent IVUS-guided transradial PCI with a 4Fr guiding catheter.

Helical Parameters

The bacterial cell is propelled through the liquid environment by means of one or more rotating flagella. The bacterial flagellum is composed of a basal body (rotary motor), hook (universal coupler), and filament (propellor). The filament is a rigid helical assembly of only one protein species — flagellin. The filament can adopt different morphologies and change, reversibly, its helical parameters (pitch and hand) as a function of mechanical stress and chemical changes (pH, ionic strength) in the environment.

Pair Analysis

The eye-brain complex allows those of us with normal vision to perceive and evaluate our surroundings in three-dimensions (3-D). The principle factor that makes this possible is parallax - the horizontal displacement of objects that results from the independent views that the left and right eyes detect and simultaneously transmit to the brain for superimposition. The common SEM micrograph is a 2-D representation of a 3-D specimen. Depriving the brain of the 3-D view can lead to erroneous conclusions about the relative sizes, positions and convergence of structures within a specimen. In addition, Walter has suggested that the stereo image contains information equivalent to a two-fold increase in magnification over that found in a 2-D image. Because of these factors, stereo pair analysis should be routinely employed when studying specimens.Imaging complementary faces of a fractured specimen is a second method by which the topography of a specimen can be more accurately evaluated.

Contralateral Ear

In studies which attempt to define the influence of various factors on recovery of hair cell integrity after acoustic trauma, an experimental and a control ear which initially have equal degrees of damage are required. With in a group of animals receiving an identical level of acoustic trauma there is more symmetry between the ears of each individual, in respect to function, than between animals. Figure 1 illustrates this, left and right cochlear evoked potential (CAP) audiograms are shown for two chinchillas receiving identical trauma. For this reason the contralateral ear is used as control.To compliment such functional evaluations we have devised a scoring system, based on the condition of hair cell stereocilia as revealed by scanning electron microscopy, which permits total stereociliar damage to be expressed numerically. This quantification permits correlation of the degree of structural pathology with functional changes. In this paper wereport experiments to verify the symmetry of stereociliar integrity between two ears, both for normal (non-exposed) animals and chinchillas in which each ear has received identical noise trauma.
