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.
