Novel and Innovative Hybrid Technique for Type A Aortic Dissection06:26

Novel and Innovative Hybrid Technique for Type A Aortic Dissection

The protocol describes ascending aortic replacement combined with endovascular coverage of the entire aortic arch with a fenestrated stent graft in a patient with acute type A aortic dissection in the absence of a tear in the aortic...

Full-root Aortic Valve Replacement by Stentless Aortic Xenografts in Patients with Small Aortic Roots

Full-root aortic valve replacement by stentless aortic xenograft is a viable option in patients with small aortic roots. We describe, a technique for the full-root implantation of stentless aortic xenografts, with emphasis on the management of the proximal suture line and coronary anastomoses, and discuss its limitations and alternative...

Experimental Investigation of Secondary Flow Structures Downstream of a Model Type IV Stent Failure in a 180° Curved Artery Test Section11:00

Experimental Investigation of Secondary Flow Structures Downstream of a Model Type IV Stent Failure in a 180° Curved Artery Test Section

Stent implants in stenosed arterial curvatures are prone to "Type IV" failures involving the complete transverse fracture of stents and linear displacement of the fractured parts. We present a protocol for detection of secondary flow (vortical) structures in a curved artery model, downstream of clinically relevant "Type IV" stent...

Types of Risk: Systematic Risk01:35

Types of Risk: Systematic Risk

Systematic risk is inherent to the market and reflects the impact of economic, financial, and geopolitical factors. It affects the entire market rather than specific stocks or industries. This type of risk is unavoidable and cannot be mitigated through diversification.
Market risk refers to the possibility that the overall stock market will decline, impacting the value of all investments. This risk is often driven by macroeconomic factors such as economic recessions, financial crises, or global...

Time-Resolved, Dynamic Computed Tomography Angiography for Characterization of Aortic Endoleaks and Treatment Guidance via 2D-3D Fusion-Imaging09:32

Time-Resolved, Dynamic Computed Tomography Angiography for Characterization of Aortic Endoleaks and Treatment Guidance via 2D-3D Fusion-Imaging

Dynamic computed tomography angiography (CTA) imaging provides additional diagnostic value in characterizing aortic endoleaks. This protocol describes a qualitative and quantitative approach using time-attenuation curve analysis to characterize endoleaks. The technique of integrating dynamic CTA imaging with fluoroscopy using 2D-3D image fusion is illustrated for better image guidance during...

Imaging In-Stent Restenosis: An Inexpensive, Reliable, and Rapid Preclinical Model

This video demonstrates how to use a preclinical inexpensive and reliable model to study pathobiological and pathophysiological processes of in-stent restenosis development. Longitudinal in vivo monitoring using OCT (Optical Coherence Tomography) and analysis of OCT images are also...
