False-positive findings with myocardial perfusion imaging (MPI) have frequently been identified in the presence of left bundle branch block (LBBB) and tend to lower the accuracy of MPI in individuals with normal coronary angiographs. Pharmacologic stress is recognized as the preferred method for MPI in patients with LBBB. In contrast, very few studies have evaluated the effect of right bundle branch block (RBBB) on MPI, and there is no consensus regarding the selection of pharmacologic versus exercise stress during MPI for the RBBB patient. In this study, we present a 45-year-old man with RBBB, who has a normal It has been reported that conduction abnormality may be related to ischemic heart disease (IHD) and therefore detection of coronary artery disease (CAD) in these patients is essential [1]. Since in left bundle branch block (LBBB) patients the exercise stress test is inconclusive, the use of a non-invasive modality, such as myocardial perfusion imaging (MPI), is applied for screening purposes [2]. However, false-positive findings with myocardial perfusion imaging (MPI) have been frequently noted in the presence of left bundle branch block (LBBB) and tend to lower the accuracy of MPI in individuals with normal coronary angiographs [3]. Pharmacologic stress is therefore recognized as the preferred method for MPI in patients with LBBB [4]. In contrast, very few studies have evaluated the effect of right bundle branch block (RBBB) on MPI, and there is no consensus concerning the selection of a pharmacologic versus an exercise stress method during MPI for the RBBB patient [5]. We present a 45-year-old man with RBBB and with a normal coronary artery angiograph, who showed abnormal myocardial perfusion with exercise MPI, and normal perfusion on dipyridamole MPI, with the aim of stimulating awareness that the stress method selected for these patients can potentially interfere with the accuracy of the data.
