Brief Summary:
The objectives of the current proposal are to analyse to what extend:
1. The use of 3D in silico simulation by FEops HEARTguide improves of influences the pre-procedural assessment and device size selection and to what extend it correlates with final implanted device size and depth compared to TEE, CT and angiography.
2. The use of 3D in silico simulation by FEops HEARTguide increases the operator's confidence in the device size selection.
A total of 100 consecutive patients for the total registry, or 15 to 20 consecutive patients per center, with standard of care follow-up at ±6 weeks and 1 year post procedure.
Detailed Description:
Left atrial appendage (LAA) occlusion (LAAO) is a well-accepted alternative to oral anticoagulant in the prevention of stroke or systemic thromboembolism in patients with atrial fibrillation (AF).1 While the occlusion is effective, the procedure can sometime be challenging. Part of the challenge is based on the high degree of variability, both at the patient level (anatomy, size, access, filling status etc); and at the device level (different architecture, size, depth, degree of conformity or compression of the device etc.). This is reflected in the percentage change in device sizes of 6.1% to 6.4%; inability to close the LAA 1% to 2.7%; complications such as embolization, tamponade etc.; residual leaks and chances for thrombus formation and subsequent stroke or systemic embolization; lengthy procedures etc.2,3 A well-prepared preprocedural planning addressing the exact anatomy of the left atrial appendage in conjunction with the optimal device size and conformability, results in optimal device selection, reduced instrumentation in the left atrium, faster and safer procedure and optimal final occlusion of the LAA. Different and complimentary techniques are being used by implanting teams, such as transoesophageal echocardiography (TEE), computed tomography (CT) scan, angiography, 3D reconstruction and 3D printing etc.
Some centres are using FEops HEARTguideTM as part of their preprocedural assessment. This is a computational tomography (CT)-based 3D in silico simulation technology suite relying on proprietary computational modelling and simulation techniques, offering physicians detailed preoperative insights into the interaction between transcatheter structural heart devices and the patient's anatomy. It is CE-marked and commercially available on the European and Canadian market. It is currently being used in 81 hospitals in 22 countries.
Belgian Hospitals who are using 3D simulations by FEops HEARTguide as part of their preprocedural assessment are asked to participate to this prospective multicentric registry. The present registry aims to compare all preprocedural imaging tools and to investigate to what extend 3D in silico simulations influences device size selection in LAAO.
