“…IVUS’s cross-sectional intraluminal view provides significant advantage in assessment of ambiguous lesions when compared to the 2D x-ray projection of angiograms alone, and has been shown to yield superior outcomes, i.e. a decrease in incidence of under-expansion and incomplete apposition to the vessel wall [ 6 , 7 ]. In situs inversus, IVUS can be particularly useful, especially when the operator is unaccustomed to seeing reverse imaging of the heart and taking into consideration the anatomical issues that can present in ways such as lesion foreshortening.…”

Situs inversus totalis is a rare anomaly in which the internal organs are transposed oppositely as mirror images. Due to its rarity, interventionalists are less likely to be acquainted with angiography in this unique population. In the case of lesion ambiguity, different invasive diagnostic tools can be used to further evaluate lesion severity, including fractional flow reserve, instantaneous wave-free ratio and intravenous ultrasound (IVUS). In this case, we discuss the usefulness of IVUS as a beneficial tool in evaluation of angiographically ambiguous lesions due to foreshortening. Dextrocardia presents unique challenges to the interventional cardiologist secondary to difficulty in acquiring adequate views and unfamiliarity with mirroring of anatomy, and thus angiography can result in inaccurately assessed lesions. We demonstrate how IVUS can be used in evaluation of such lesions for more accurate evaluation, precision in stent placement and in turn better patient outcomes.
