Interval ablation
WebFeb 21, 2024 · The usual target for the ablation line is the central isthmus because the CTI is narrowest at this point (i.e., distance from TVA to IVC) and has the thinnest musculature. This site is located at 6 o’clock in the LAO view (see Fig. 11.7 ). One drawback to ablation of the central isthmus is the frequent occurrence of pouches in this region. WebIntroduction.
