3D Anatomy

Preprocedural imaging and its integration into electroanatomical mapping (EAM) is commonly used in atrial fibrillation (AF) ablation. However, intraprocedural imaging based on rotational angiography (DynaCT Cardiac) may be superior in terms of actuality and may lead to an improved work-flow. Feasibility of integrating Dyna CT Cardiac into EAM has not yet been shown. In 23 patients (62±7 years, 16 male) undergoing catheter ablation of paroxysmal (n=10) or persistent (n=13) AF, we intraprocedurally performed rotational angiography enhanced by contrast agent applied to the pulmonary artery with offline segmentation of left atrium (LA) and pulmonary veins (PV). Fig 1 depicts reconstructed LA and PV-anatomy directly importet into CARTOMerge. Distances between the 2 modalities were analyzed. Direct image integration of prereconstructed 3D-anatomy was feasible in all patients. Procedure time was 156 ± 24 minutes including 11 ± 3 minutes for DynaCT Cardiac registration and segmentation. 132 ± 74 mapping points were taken. Mapping points deviated to intraprocedural DynaCT Cardiac 3D-reconstructions by 2.2 ± 0.4 mm (2.3 ± 0.5 mm in patients suffering from paroxysmal atrial fibrillation (AF) vs. 2.1 ± 0.40 mm persistent AF, n.s.). No complications occured. Integration of intraprocedural Dyna CT Cardiac into EAM was feasible and fast. The work-flow seemed to be improved by avoiding additional preprocedural imaging. The novel modality is highly accurate in comparison to EAM.

Shape change of the left atrium (LA) and LA appendage in atrial fibrillation (AF) patients is hypothesized to be linked to AF pathology and to play a role in thrombogenesis; however, many aspects of shape variation in the heart are poorly understood. To date, studies of the LA shape in AF have been limited to empirical observation and summary metrics, such as volume and its likeness to a sphere. This paper describes a more comprehensive approach to the study of the LA shape through the use of computationally derived statistical shape models. We describe practical approaches that we have developed to extract shape parameters automatically from the three-dimensional MR images of the patient. From these images and our techniques, we can produce a more comprehensive description of LA geometric variability than that has been previously possible. We present the methodology and results from two examples of specific analyses using shape models: (1) we describe statistically significant group differences between the normal control and AF patient populations ( n = 137) and (2) we describe characteristic shapes of the LA appendage that are associated with the risk of thrombogenesis determined by transesophageal echocardiography ( n = 203).
