Abstract: A computer that determines at least an anatomic feature of a left atrial appendage (LAA) is described. During operation, the computer generates a 3D image associated with an individual's heart. This 3D image may present a view along a perpendicular direction to an opening of the LAA. Then, the computer may receive information specifying a set of reference locations. For example, the set of reference locations may include: a location on a circumflex artery, a location between a superior portion of the LAA and a left pulmonary vein, and/or a location on a superior wall of the LAA and distal to trabeculae carneae. Next, the computer automatically determines, based, at least in part, on the set of reference locations, at least the anatomical feature of the LAA, which is associated with the opening of the LAA and a size of a device used in an LAA closure (LAAC) procedure.

Abstract: Fire extinguishing systems and methods, such as for combating compartment fires, can include or use wet and dry agents such as water droplets and aerosol-based particulate extinguisher agents. In an example, an extinguishing system includes a centralized extinguishing controller that can selectively provide the wet and dry agents to a compartment or environment. In other examples, dedicated dispenser systems separately, but optionally concurrently, provide water and aerosol-based agents to combat a compartment fire.

Abstract: A computer that determines at least an anatomic feature associated with an aortic valve is described. During operation, the computer generates a 3D image associated with an individual's heart. This 3D image may present a view along a perpendicular direction to a 2D plane in which bases of a noncoronary cusp, a right coronary cusp and a left coronary cusp reside. Then, the computer may receive information specifying a set of reference locations that are associated with an aortic-root structure. Next, the computer automatically determines, based, at least in part, on the set of reference locations, at least the anatomical feature, which is associated with an aortic valve of the individual and a size of an aortic-valve device used in a transcatheter aortic-valve replacement (TAVR) procedure.
