Cardiac anatomy is complex and its understanding is essential for the interventional arrhythmologist. The first difficulty is the terminology used to (PACE 2010; 33:497-507) fluoroscopy, ablation, mapping, anatomy, attitudinal nomenclature
IntroductionThe establishment of radiofrequency catheter ablation as the mainstay in the treatment of tachycardia in man has renewed the interest in cardiac morphology. The interventional arrhythmologist has drawn attention not only to the gross anatomic details of the heart, but also to some architectural and histological characteristics of various cardiac regions that are relevant to the understanding of the tachycardia substrates, and the potential complications of catheter ablation. Progress in these areas has not ceased. In this review, therefore, the first of a proposed series, we update and expand previous accounts of cardiac anatomy as seen by the arrhythmologist.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
