To the Editor:
We read with great interest the recent article by Heng and colleagues1 describing the follow-up of 57 patients with repaired tetralogy of Fallot who underwent pulmonary valve replacement (PVR) with cardiac magnetic resonance imaging. They conclude that significant right heart structural reverse remodeling takes place immediately after PVR, followed by gradual further biological remodeling during follow-up.
The analysis concerned 57 relatively healthy individuals, given their absence of contraindications to cardiac magnetic resonance, good kidney function, and the elective setting. The authors, however, did not disclose the selection criteria that left them with only 57 of a potentially larger …
