Conclusions
Late-pCT was highly useful in the
assessment of intracardiac thrombi in patients with persistent or
long-standing AF before CA. Compared to TEE, CT was noninvasive and
reproducible, and associated with a significantly lower degree of
differences in the evaluation performed by physicians. The presence of
residual contrast medium in the LAA, as detected on late-pCT, is
indicative of a low blood velocity.
