Question: Is echocardiographic examination is useful for surgical method decision in patients with tetralogy of Fallot (TOF)?
Finding: Various echocardiographic parameters serve as predictors for determining surgical methods for TOF patients. However, the PV morphology and tissue characteristics should also be considered.
Meaning: A full dependence on the size of the pulmonary valve annulus (PVA), the z score, and the ratio of the size of PVA to aortic valve annulus or descending aorta surgery may result in inadequate surgical results during TOF total correction. |

Purpose: This study aimed to analyze changes in QRS duration and cardiothoracic ratio (CTR) following pulmonary valve replacement (PVR) in patients with tetralogy of Fallot (TOF).
Methods: Children and adolescents who had previously undergone total repair for TOF (n=67; median age, 16 years) who required elective PVR for pulmonary regurgitation and/or right ventricular out tract obstruction were included in this study.... |
