Stent Longitudinal Strength Assessed Using Point Compression

Stent longitudinal strength assessed using point compression: insights from a second-generation, clinically related bench test.

BACKGROUND Stent longitudinal distortion, while infrequent, can lead to adverse clinical events. Our first bench comparison of susceptibility of different stent designs to distortion applied force to the entire circumference of the proximal stent hoop. The test increased understanding of stent design and led to recommendations for design change in some. Our second-generation test more closely m...

Treatment of longitudinal stent compression under intravenous ultrasound guidance

RATIONALE Longitudinal stent compression is a rare phenomenon, which has been increasingly reported in recent years. PATIENT CONCERNS Following 2 stents implanted into the middle and proximal segments of the left anterior descending (LAD) artery, longitudinal stent compression occurred when a post-dilation balloon was introduced into the proximal stent opening. DIAGNOSE The intravenous ultr...

Longitudinal stent compression demonstrated by angiographic "wedding band" and 3-dimensional optical coherence tomography.

A Fractional Flow Reserve Guidewire Causing Longitudinal Stent Compression and Successful Recovery

Longitudinal stent deformation (LSD) is a rare complication but can occur during coronary intervention. We report a case with LSD of the distal edge, documented by an optical coherence tomography investigation and successfully recovered.

Baroreflex Coupling Assessed by Cross-Compression Entropy

Estimating interactions between physiological systems is an important challenge in modern biomedical research. Here, we explore a new concept for quantifying information common in two time series by cross-compressibility. Cross-compression entropy (CCE) exploits the ZIP data compression algorithm extended to bivariate data analysis. First, time series are transformed into symbol vectors. Symbol...
