3-Dimensional Computed Tomographic (CT) Imaging in the Context of Transcatheter Valvular Interventions (pp. 25-56)
Authors: (Paul Schoenhagen, Sandy S. Halliburton)
Abstract: Less invasive surgical and transcatheter procedures for valvular and structural heart disease are characterized by limited direct exposure of the operative field. Therefore pre-procedural planning and intra-operative decision-making increasingly relies on image guidance.
The need for pre- and intra- operative visualization has been met by novel 3-dimensional imaging approaches. Pre-procedural 3-D imaging provides detailed understanding of the operative field for surgical/interventional planning. Subsequent integration of imaging during the procedure allows real-time guidance.
This chapter describes the emerging experience with computed tomography for interventional guidance of valvular procedures. Other modalities allowing 3-D imaging, including rotational angiography (C-arm CT), echocardiography, and MRI are briefly compared, but are discussed in more detail in other chapter of the book.
