Embodiment Construction

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

[0017] Anatomical models enable therapy planning through virtual device placement and deployment. Computational models of tissue biomechanics coupled with organ / device interaction models have the potential to simulate device deployment and analyze resulting tissue deformations and stresses, providing measures of anchoring stability,...

Abstract

The invention relates to left atrial appendage closure guidance in medical imaging. An ultrasound imager (20) provides for LAA closure guidance. Using ultrasound imaging allows for modeling (32) overtime (e.g., throughout a heart cycle). An anatomy model of the LAA over time is used to create a biomechanical model personalized to the patient. The personalized models and a model of one or more closure devices are used to select (40) a closure device for the patient appropriate for the entire heart cycle and to guide (44) placement of the selected closure device during an implantation.

Description

Background technique [0001] This example relates to left atrial appendage (LAA) closure. The LAA is an anatomical structure that may contribute to the formation of life-threatening thrombi. 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 thrombus. Key aspects of the process are device selection based on anatomical considerations and planning of the device landing area. Computed tomography (CT) data or three-dimensional transesophageal echocardiography (3D TEE) data can be used to select the 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 s...
