Abstract
Dept of Clinical Physiology, Lund University, Lund, Sweden Full list of author information is available at the end of the article Figure 1 Comparison of kinetic energy (KE) (top) and KE indexed for ventricular stroke volume (SV) (bottom) between ToF patients and controls in both left ventricle (LV) and right ventricle (RV). Bar and whiskers show mean ± SD. Sjoberg et al. Journal of Cardiovascular Magnetic Resonance 2016, 18(Suppl 1):P184 http://www.jcmr-online.com/content/18/S1/P184
Highlights
There is a persisting debate regarding indications and timing of pulmonary valve replacement in patients with pulmonary insufficiency after repair of Tetralogy of Fallot (ToF)
Peak systolic kinetic energy (KE), as well as KE indexed for the stroke volume (SV) of the ventricle was lower in the left ventricle of ToF patients than in controls
Peak diastolic KE was higher in the right ventricle of patients than in controls, when KE was indexed for SV, Figure 1
Summary
There is a persisting debate regarding indications and timing of pulmonary valve replacement in patients with pulmonary insufficiency after repair of Tetralogy of Fallot (ToF). The status of right ventricular function is important is this decision but remains elusive. CMR enables quantification of ventricular kinetic energy (KE) which may provide improved understanding of the pathophysiology of the dilated ventricle with impaired function.
