Key result
Fast MR flow mapping revealed abnormal recovery of left ventricular function after supine bicycle exercise in 6 asymptomatic patients with corrected tetralogy of Fallot compared to 9 healthy controls.
Why the study?
Does fast MR flow mapping detect abnormal recovery of left ventricular function after exercise in asymptomatic patients with corrected tetralogy of Fallot compared to healthy controls?
Observational (n=15)
Does fast MR flow mapping detect abnormal recovery of left ventricular function after exercise in asymptomatic patients with corrected tetralogy of Fallot compared to healthy controls?
Fast MR flow mapping can successfully detect abnormal delayed recovery of left ventricular stroke volume after exercise in asymptomatic patients with corrected tetralogy of Fallot.
No takes yet. Share an insight, caveat, or question.
Does not support routine use in asymptomatic repaired tetralogy of Fallot; leaves open utility of fast MR flow mapping for detecting subclinical LV impairment.
Roest et al. (2003) conducted an observational in Corrected tetralogy of Fallot (n=15). Fast magnetic resonance (MR) flow mapping after supine bicycle exercise vs. Healthy control subjects was evaluated on Left ventricular (LV) function during recovery from exercise. Fast MR flow mapping revealed abnormal recovery of left ventricular function after supine bicycle exercise in 6 asymptomatic patients with corrected tetralogy of Fallot compared to 9 healthy controls.
