Cardiac Computed Tomography and Magnetic Resonance Imaging of the Tricuspid Valve: Preprocedural Planning and Postprocedural Follow-up
2022, Interventional Cardiology ClinicsCitation Excerpt :Preprocedural CCT can provide individually tailored optimal fluoroscopic viewing angles for TTVI. In practice, the main procedural viewing angles are the right anterior oblique (RAO) angles for long-axis views of the right-sided chambers, coplanar to the TA, and a caudal left anterior oblique (LAO) angle for a short-axis (en-face) view of the TV, orthogonal to the TA (Fig. 8).28,29 Specifically, a more caudal RAO angle provides a 2-chamber (or inflow) view and a more cranial RAO angle provides a 3-chamber (or inflow-outflow) view.
Intraprocedural Imaging of Transcatheter Tricuspid Valve Interventions
2019, JACC: Cardiovascular ImagingCitation Excerpt :The simultaneous 3D TEE view helps obtain a spatial vision of the TV annulus, the leaflets, and the atrial wall. The second fluoroscopic projection is the en face view (usually a left anterior oblique caudal view or “LAO/CAU”) of the TV, in which the valve area can be fully evaluated looking from the RV side (14). This projection is useful to navigate the catheter to the target and is the same view as the 3D echocardiography en face, seen from the RV.
Fluoroscopic Anatomy of Right-Sided Heart Structures for Transcatheter Interventions
2018, JACC: Cardiovascular InterventionsCitation Excerpt :In this view, it is possible to appreciate the trajectory of the CS. This view is potentially useful for targeting the structures of interest by matching the anatomic disposition of the leaflets of the fluoroscopic view with a modified (upside down) transgastric transesophageal echocardiography (TEE) view, seen from the ventricular side (17). The short-axis view is useful to differentiate the 3 leaflets of the TV and potentially helpful in guiding procedures targeting these structures, providing the operator with the necessary information to navigate the right atrium and ventricle through the valve.
Transcatheter Tricuspid Valve Interventions: Landscape, Challenges, and Future Directions
2018, Journal of the American College of CardiologyCitation Excerpt :Predicting the best fluoroscopic projection: Similar to transaortic and transmitral valve replacement, CT imaging is helpful to provide coplanar fluoroscopic projections yielding coaxial device deployment. Two essential fluoroscopic projections have been proposed: the right anterior oblique view (obtaining a long-axis view to assess the device’s trajectory and coaxiality with the TA) and the left anterior oblique caudal view (mimicking the surgical “en face” view seen from the right ventricular side) (33). Table 2 summarizes the most important device-specific anatomic considerations during CT pre-operative assessment.
