Conventional radiography and computed tomography of cardiac assist devices


Scheffel, H; Stolzmann, P; Wilhelm, M J; Lachat, M; Desbiolles, L; Leschka, S; Frauenfelder, T; Schertler, T; Marincek, B; Alkadhi, H (2009). Conventional radiography and computed tomography of cardiac assist devices. European Radiology, 19(9):2097-2106.

Abstract

Abstract Patients intended for circulatory
support by cardiac assist
devices (CAD) usually suffer from
end-stage acute or chronic heart
failure. Since the introduction of CAD
in 1963 by DeBakey and coworkers,
the systems have gone through a
substantial evolution and have been
increasingly used in the intervening
decades. The spectrum of CAD
includes a variety of systems serving
to assist the systolic function of the left
ventricle, the right ventricle, or both.
Conventional radiography and multislice
spiral computed tomography
(CT) are the most commonly used
radiological techniques for imaging
patients with a CAD. CT is very useful
for evaluating CAD systems by using
both two- and three-dimensional reconstructions
of the volumetric data
sets. The two techniques together
allow for the comprehensive assessment
of patients with devices by
imaging the in- and outflow cannulae,
the anastomoses, the position of the
pump, as well as associated complications.
A close collaboration with
cardiac surgeons with expertise in the
field of circulatory support is deemed
necessary for adequate image interpretation.
This article describes the
technical diversity of the currently
available CAD systems. The imaging
characteristics on conventional radiography
and multislice spiral CT as
well as the typical complications of
their use are demonstrated.
