Tetralogy of Fallot

Non-Invasive Imaging


The session on Tetralogy of Fallot covered the main areas of clinical interest and controversy, namely the timing of pulmonary valve replacement, the optimum imaging of the right ventricle and its outflow tract and the use of stress imaging.
Dr Valsangiacomo discussed optimum timing of pulmonary valve replacement and the use of MR data in clinical decision-making. In particular, she focused on the use of right ventricular end diastolic volume as a useful biomarker with a value of 160ml/m2 being used as a clinical threshold.
Dr Muthurangu discussed the use of MR in planning interventions on the right ventricular outflow tract. He emphasized the importance of three-dimensional and cine information in clinical decision making. He also discussed the development of devices and the requirement for more sophisticated analysis.
Dr Kilner mainly concentrated on new MR methods of assessing the complex structure and function of the right ventricle. He covered MR methods such as displacement encoding, which can be used to accurately measure RV strain in all directions. He also highlighted the important differences between the trabecular right ventricle and the compacted left ventricle.
Dr Helbing described the new area of stress imaging for assessment of the right ventricle in patients with Tetralogy of Fallot. In particular, he concentrated on the use of dobutamine as a better method of stratifying these patients. In addition, he also discussed an MR study demonstrating that chronic exercise does not have a deleterious affect on RV volumes or function in these p
