Purpose: 3D printed patient specific vascular models provide the ability to perform precise and repeatable benchtop experiments with simulated physiological blood flow conditions. This approach can be applied to CT-derived patient geometries to determine coronary flow related parameters such as Fractional Flow Reserve (FFR). To demonstrate the utility of this approach we compared bench-top results with non-invasive CT-derived FFR software based on a computational fluid dynamics algorithm and catheter based FFR measurements...

INTRODUCTION: Reversible edema is a part of any radiofrequency ablation but its relationship with contact force is unknown. The goal of this study was to characterize through histology and MRI, acute and chronic ablation lesions and reversible edema with contact force. METHODS AND RESULTS: In a canine model (n = 14), chronic ventricular lesions were created with a 3.5 mm tip ThermoCool SmartTouch (Biosense Webster) catheter at 25W or 40W for 30 sec. Repeat ablation was performed after 3 months to create a second set of lesions (acute)...

We have used a new device to prevent pulmonary embolism during pharmacomechanical thrombectomy in a 25-year-old postpartum woman. The Angel® catheter (BiO2 Medical Inc., Golden, CO, USA) is a temporary device that combines the functions of a vena cava filter (VCF) with those of a triple-lumen central venous catheter. Normally, a VCF is implanted to prevent pulmonary embolism during pharmacomechanical thrombectomy. However, the complications associated with VCFs increase with time, not all of the filter can always be retrieved, and there can be iatrogenic effects both during implantation and retrieval...

Rotational activations, or spiral waves, are one of the proposed mechanisms for atrial fibrillation (AF) maintenance. We present a system for assessing the presence of rotational activity from intracardiac electrograms (EGMs). Our system is able to operate in real-time with multi-electrode catheters of different topologies in contact with the atrial wall, and it is based on new local activation time (LAT) estimation and rotational activity detection methods. The EGM LAT estimation method is based on the identification of the highest sustained negative slope of unipolar signals...

There has been increasing use of a novel combined femoral venous sheath, catheter and retrievable self-expanding and collapsible diamond-shaped IVC filter (Angel® Catheter, BiO2 Medical), in severely injured patients who cannot receive anticoagulation. As the filter is not detached from the catheter/sheath, it should be easily retrieved. Outcomes included in large registries demonstrate a high safety profile and a 100% retrieval rate. However, at our institution-a Level 1 major UK trauma centre with 4 years of substantial experience in using this device-we've encountered three cases of device fracture and subsequent complicated retrieval dating from Dec 2016 to March 2017...
