Three‐dimensional computed tomography in the cardiac catheterization laboratory

Abstract

We have demonstrated the ability to delineate cardiovascular structures of interest on the "real-time" fluoroscopic image using CT fusion. Future studies should address whether this technology can reduce overall contrast administration and radiation dose.

The value of flat-detector computed tomography during catheterisation of congenital heart disease

“…Furthermore, accurate assessment of valve function and anatomy of the great vessels, with some limitations even of the coronary arteries is possible [15]. FD-CT imaging in the context of invasive catheterisation has so far mainly been used in neuroradiology, tumour embolisation, apical aortic valve replacement in adults, as well as in electrophysiology interventions [2,3,5,6,[16][17][18][19]. As a new technology it also offers 3D imaging during cardiac catheterisation and this is definitely an extension of the hitherto available imaging techniques.…”

Percutaneous Paravalvular Leak Closure

“…15 After identifying the location of the PVL on TEE, markings are made on a preprocedural noncontrast CT ( Figure 7A). We then acquire a CT-like image using the catheterization laboratory's C-arm (syngo DynaCT Cardiac, Siemens Healthcare, Forcheim, Germany) to establish the position of the patient on the table.…”

Plugging Holes

“…Several different methods to overlay 3D information from either transesophageal echocardiography or CT scan to fluoroscopic images have been used. 5,6 Three-dimensional transesophageal echocardiographic guidance for device manipulation is also critically important. Understanding of the anatomy and details of the devices is paramount to the success of these procedures, and the authors should be congratulated for their technical skills.…”
