Embodiment Construction

[0016] LAA closure guidance is provided with an ultrasound-based system. Ultrasound scans provide efficient LAA closure planning and guidance from anatomical quantification, device selection, path planning, and treatment delivery with fast and reproducible measurements and quantification tools. The ultrasound-based system enables efficient and robust characterization and quantification of LAA anatomy. The ultrasound-based system automatically provides an intuitive rendering of the LAA for planning and guidance, key measurements, and a simulation system for device selection. Integrated multimodality systems can combine ultrasound and fluoroscopic imaging.

[0017] Anatomical models enable therapy planning through virtual device placement and deployment. Computational models of tissue biomechanics coupled with models of organ / device interaction have the potential to simulate device deployment and analyze resulting tissue deformation and stress, providing metrics for anchorage ...

Abstract

The invention relates to left atrial appendage closure guidance in medical imaging. The ultrasound imager (20) provides guidance for LAA closure. Modeling over time (eg, over the heart cycle) is allowed for using ultrasound imaging (32). The anatomical model of the LAA over time is used to create a biomechanical model personalized to the patient. The personalized model and models of one or more closure devices are used to select (40) a suitable closure device for the patient throughout the heart cycle and to guide (44) placement of the selected closure device during implantation .

Description

Background technique [0001] This embodiment involves left atrial appendage (LAA) closure. LAAs are anatomical structures that may contribute to the formation of life-threatening blood clots. Surgical excision of the LAA structure can treat or prevent the condition. The closure device can be implanted via a catheter in a much less invasive manner for the patient. These closure devices behave like a plug that covers the LAA and prevents the accumulation of blood and the formation of thrombi. Critical aspects of the process are device selection based on anatomical considerations and planning of device parking areas. Computed tomography (CT) data or three-dimensional transesophageal echocardiography (3D TEE) data can be used to select an appropriate closure device. [0002] In clinical practice, LAA closure planning and guidance uses the physician's manual interaction with ultrasound and CT datasets. Accurate quantification and characterization of LAA from medical images has ...
