The Stanford Catheterization Angiography Laboratory aims to provide minimally invasive catheter based radiological procedures to inpatients and outpatients for diagnostic evaluation and/or therapeutic intervention.
Our service for Transcatheter Aortic Valve Replacement (TAVR) utilizes 3D imaging and measurements to enhance procedural planning. These images may be useful for mapping the intricate landscape of cardiac structures and vasculature, ensuring each transcatheter heart valve (THV) procedure is customized to the patient's unique anatomy.
Using 3D imaging in the TAVR planning process allows for the evaluation of aortic root dimensions, annulus size, and the morphology of the aortic valve complex. It provides insights into the spatial relationships between the aortic valve and surrounding coronary arteries, highlighting potential challenges and guiding the selection of the appropriate valve size and optimal implantation approach.
Additionally, CT angiography assesses the iliofemoral arteries, determining their suitability for catheter access by identifying any calcifications, occlusions, or tortuosities that could impact the procedure.
Our 3D Printing Service provides anatomical 3D printed models for surgical planning and education. 3D prints can be requested during the 3D imaging ordering process. To achieve optimal results we require high-resolution CT or MRI scans. Once the scan is obtained, we begin the process by segmenting the medical images to isolate specific anatomical structures. This segmented data is then converted into a 3D model and reviewed by the requestor.
Final models are produced using advanced 3D printing technologies such as Fused Deposition Modeling (FDM), Stereolithography (SLA), and PolyJet. We offer hand delivery for on-site requestors and mail delivery for those at other Stanford locations. Additionally, we are exploring the development of custom cutting guides to assist in surgical procedures.
