Key result
CT and MRI can reveal architectural changes in the right ventricular outflow tract, such as scar and fibrofatty tissue, which are relevant for electrophysiologic assessment and ablation of arrhythmias.
CT and MRI are valuable tools for assessing RVOT function and identifying structural abnormalities that serve as targets for ventricular tachycardia ablation.

CT/MRI aid RVOT assessment for VT ablation; leaves open prospective validation of imaging protocols.
OBJECTIVE: MRI and CT have become the ideal methods for assessing the complex function of the conotruncal region, including the right ventricular outflow tract (RVOT). In this review, we focus on the role of CT and MRI to evaluate RVOT function in relation to developmental malformations. CONCLUSION: We discuss the role of imaging pertinent to electrophysiologic assessment for cardiac arrhythmias. The RVOT is an important ablation target for radiofrequency ablation of ventricular tachycardia. Architectural changes of the myocardial strands in the RVOT, scar, and fibrofatty tissue may play a role in the development of RVOT ventricular arrhythmias. With CT and MRI, some of these changes can be revealed.

Saremi et al. (2012) conducted a review in Right ventricular outflow tract (RVOT) developmental malformations and cardiac arrhythmias. CT and MRI was evaluated. CT and MRI can reveal architectural changes in the right ventricular outflow tract, such as scar and fibrofatty tissue, which are relevant for electrophysiologic assessment and ablation of arrhythmias.
