    1. Novel ultrahigh molecular weight amorphous PLLA bioresorbable coronary scaffold upsized up to 0.8 mm beyond nominal diameter: An OCT and histopathology study in porcine coronary artery model

      Novel ultrahigh molecular weight amorphous PLLA bioresorbable coronary scaffold upsized up to 0.8 mm beyond nominal diameter: An OCT and histopathology study in porcine coronary artery model

      Objectives The aim of the study was to evaluate the biomechanical properties and healing pattern of novel sirolimus-eluting, ultrahigh molecular weight amorphous poly-L-lactic acid bioresorbable scaffolds (S-BRS) that have been postdilated by 0.55 and 0.8 mm beyond the nominal diameters within the pressure-diameter compliance chart range. Background Due to the inherent limitations of bioabsorbable polymeric materials, overexpansion/upsizing may be very limited for some BRS such as the benchmark Absorb BVS. The unique biomechanical properties of the novel S-BRS may allow it to be safely upsized. Methods and Results 12 coronary arteries of 4 healthy Yucatan mini-swine underwent ...

    2. Optimizing flushing parameters in intracoronary optical coherence tomography: an in vivo swine study

      Optimizing flushing parameters in intracoronary optical coherence tomography: an in vivo swine study

      Intracoronary optical frequency domain imaging (OFDI), requires the displacement of blood for clear visualization of the artery wall. Radiographic contrast agents are highly effective at displacing blood however, may increase the risk of contrast-induced nephropathy. Flushing media viscosity, flow rate, and flush duration influence the efficiency of blood displacement necessary for obtaining diagnostic quality OFDI images. The aim of this work was to determine the optimal flushing parameters necessary to reliably perform intracoronary OFDI while reducing the volume of administered radiographic contrast, and assess the influence of flushing media choice on vessel wall measurements. 144 OFDI pullbacks were acquired together ...
