Study design: Observational Study
Abstract: OBJECTIVE: Despite progresses in surgical correction of Tetralogy of Fallot, pulmonary insufficiency and progressive dysfunction of the right ventricle impress its long-term prognosis. In this study we examined the correlations between QRS duration, pulmonary insufficiency and right ventricular performance index. METHODS: We enrolled 57 repaired Tetralogy of Fallot patients. QRS duration on electrocardiogram, pulmonary regurgitation index (regurgitation time to diastolic time ratio), and right ventricular myocardial performance index were measured. FINDINGS: There was a strong inverse correlation between QRS duration and pulmonary regurgitation index. However, significant correlation did not exist between QRS duration and right ventricular myocardial performance index. QRS duration ≥160 ms predicted severe pulmonary regurgitation with 100% sensitivity and 87% specificity. CONCLUSION: Increased QRS duration can predict severity of pulmonary regurgitation.
