The establishment of radiofrequency catheter ablation techniques as the mainstay
in the treatment of tachycardia has renewed new interest in cardiac anatomy. The
interventional arrhythmologist has drawn attention not only to the gross anatomic
details of the heart but also to architectural and histological characteristics
of various cardiac regions that are relevant to the development or recurrence of
tachyarrhythmias and procedural related complications of catheter ablation. In
this review, therefore, we discuss some anatomic landmarks commonly used in
catheter ablations including the terminal crest, sinus node region, Koch's
triangle, cavotricuspid isthmus, Eustachian ridge and valve, pulmonary venous
orifices, venoatrial junctions, and ventricular outflow tracts. We also discuss
the anatomical features of important structures in the vicinity of the atria and
pulmonary veins, such as the esophagus and phrenic nerves. This paper provides
basic anatomic information to improve understanding of the mapping and ablative
procedures for cardiac interventional electrophysiologists.
