Aortic Root Enlargement during Aortic Valve Replacement in Adults
Aortic valve replacement is a gold standard in the treatment of patients with severe aortic stenosis or combined aortic pathology. However, aortic valve pathology is often associated with a narrow aortic orifice, particularly in patients with severe ...

Detecting total hip replacement prosthesis design on preoperative radiographs using deep convolutional neural network [PDF]
Identifying the design of a failed implant is a key step in preoperative planning of revision total joint arthroplasty. Manual identification of the implant design from radiographic images is time consuming and prone to error. Failure to identify the implant design preoperatively can lead to increased operating room time, more complex surgery ...

Two-Stream Regression Network for Dental Implant Position Prediction [PDF]
In implant prosthesis treatment, the design of the surgical guide heavily relies on the manual location of the implant position, which is subjective and prone to doctor's experiences. When deep learning based methods has started to be applied to address this problem, the space between teeth are various and some of them might present similar texture ...

ABSTRACT Background Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) is a complication linked to poor outcomes. The prognostic impact of mild PVR, particularly in patients with elevated preprocedural left ventricular (LV) filling pressure, remains uncertain.

Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics [PDF]
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease. However, valves may dysfunction leading to adverse hemodynamic conditions.

Abstract A 31‐year‐old male presented with unexplainable symptoms of heart failure including recurrent fatigue and orthopnoea after total arch replacement for type A aortic dissection 2 months ago. Computed tomography angiography detected a severe intra‐luminal stenosis, and we successfully implanted a balloon‐expandable stent to dilate the stenosis ...
