Defining Normative Mixed-Breed Ovine Spine Anatomy Using Computed Tomography and Magnetic Resonance Imaging Open
The availability of suitable preclinical models is critical for developing novel therapeutic interventions. Ovine models are particularly useful for studying spinal diseases due to their similarity in size and weight to humans. However, ev…

Intracardiac Induced Ventricular Fibrillation for the Euthanasia of Sheep Open
Euthanasia is the humane termination of an animal's life and an important consideration for scientists, veterinarians, regulators, and others contemplating investigations involving animals. Techniques for euthanasia must induce the most ra…

Using evoked compound action potentials to quantify differential neural activation with burst and conventional, 40 Hz spinal cord stimulation in ovines Open
Introduction and Objectives: Unlike conventional dorsal spinal cord stimulation (SCS)—which uses single pulses at a fixed rate—burst SCS uses a fixed-rate, five-pulse stimuli cluster as a treatment for chronic pain; mechanistic explanation…

Characterization of Phrenic Nerve Response to Pulsed Field Ablation Open
Background: Phrenic nerve palsy is a well-known complication of cardiac ablation, resulting from the application of direct thermal energy. Emerging pulsed field ablation (PFA) may reduce the risk of phrenic nerve injury but has not been we…

Safety and chronic lesion characterization of pulsed field ablation in a Porcine model Open
Background Pulsed field ablation (PFA) has been identified as an alternative to thermal‐based ablation systems for treatment of atrial fibrillation patients. The objective of this Good Laboratory Practice (GLP) study was to characterize th…

Reduction in Pulmonary Vein Stenosis and Collateral Damage With Pulsed Field Ablation Compared With Radiofrequency Ablation in a Canine Model Open
Background: Pulmonary vein (PV) stenosis is a highly morbid condition that can result after catheter ablation for PV isolation. We hypothesized that pulsed field ablation (PFA) would reduce PV stenosis risk and collateral injury compared w…

Intracardiac pulsed field ablation: Proof of feasibility in a chronic porcine model Open
Intracardiac PFA can be feasibly delivered from a circular catheter to create fibrotic lesions that have acute electrical effects, without injury to nontargeted tissue.

Echocardiographic assessment of aortic valve annular and left ventricular outflow tract diameter in conscious and anesthetized adult sheep prior to prosthetic aortic valve implantation Open
Objective: Prosthetic heart valve implantation is commonly performed in patients that have valvular heart disease. Prior to clinical evaluation of newly developed prostheses, preclinical animal studies are performed for the assessment of b…
