Abstract Surgical repair of Tetralogy of Fallot has excellent outcomes, with over 90% of patients alive at 30 years. The ideal time for surgical repair is between 3 and 11 months of age. However, the symptomatic neonate with Tetralogy of Fallot may require earlier intervention: either a palliative intervention (right ventricular outflow tract stent, ductal stent, balloon pulmonary valvuloplasty, or Blalock-Taussig shunt) followed by a surgical repair later on, or a complete surgical repair in the neonatal period. Indications for palliation include prematurity, complex anatomy, small pulmonary artery size, and comorbidities. Given that outcomes after right ventricular outflow tract stent palliation are particularly promising – there is low mortality and morbidity, and consistently increased oxygen saturations and increased pulmonary artery z-scores – it is now considered the first-line palliative option. Disadvantages of right ventricular outflow tract stenting include increased cardiopulmonary bypass time at later repair and the stent preventing pulmonary valve preservation. However, neonatal surgical repair is associated with increased short-term complications and hospital length of stay compared to staged repair. Both staged repair and primary repair appear to have similar long-term mortality and morbidity, but more evidence is needed assessing long-term outcomes for right ventricular outflow tract stent palliation patients.

Repaired Tetralogy Of Fallot

AbstractBackgroundPatients with repaired tetralogy of Fallot may develop symptomatic and haemodynamic deterioration for many reasons such as arrhythmia, pulmonary regurgitation, and impairment in ventricular function. We describe a consecutive group of patients whose main clinical problem was atrial tachyarrhythmias.AimsTo describe the clinical outcome of atrial tachyarrhythmias occurring late after surgical repair of tetralogy of Fallot; to define the circuits/foci responsible for these atrial tachyarrhythmias; to evaluate the outcome of computer-assisted mapping and catheter ablation in this patient group.Methods and resultsConsecutive patients with surgically repaired tetralogy of Fallot and atrial tachyarrhythmias, who underwent catheter ablation between January, 2001 and June, 2007, were identified retrospectively from case records. Computer-assisted mapping was performed in all using either EnSite® (St Jude Medical Inc.) arrhythmia mapping and intra-cardiac catheter guidance system or CARTO™ (Biosense Webster Inc.) electroanatomical mapping systems. Ten patients (four males) with a median age of 39 plus or minus 8 years were studied. The total number of atrial tachyarrhythmias identified was 22 (six macro-reentrant, 16 micro-reentrant/focal). In nine patients, catheter ablation led to improvement in arrhythmia episodes and/or symptoms during follow-up of 41 plus or minus 20 months. Following ablation(s), five patients required pacing for pre-existing conduction disease and five needed further surgery for haemodynamic indications. All patients remained on anti-arrhythmic drugs.ConclusionsPatients with surgically repaired tetralogy of Fallot and atrial tachyarrhythmias typically have multiple arrhythmic circuits/foci arising from a scarred right atrium. Catheter ablation reduces arrhythmia frequency and improves symptoms. However, hybrid management is often required, comprising drugs, pacing, and further surgery tailored to the individual.

Introduction & Hypothesis: There is limited information on right atrial (RA) function in the congenital heart defects. RA volume and function may give insight into the right ventricle (RV) diastolic function. We sought to assess RA function in tetralogy of Fallot (TOF) patients prior to and after complete surgical repair. Methods: Infants with TOF prior to complete repair were included for retrospective chart review and offline analysis of 2-dimensional echocardiograms (echo) before and after surgical repair. RA phasic volumes and stroke volumes were calculated. All volumes were indexed to body surface area. Results: There were 40 infants with TOF (45% females), of which 70% had pulmonary stenosis, 30% pulmonary atresia. Roughly 85% and 60% had 3, or more, echo available pre- and postoperatively. Table 1 (attached) shows the patient characteristics and phasic RA volumes. The indexed RA phasic volumes were in normal range in initial echo prior to surgery. We used normal index RA phasic volumes published by European Society of Echocardiography. There was the increasing trend of indexed RA phasic volume on follow up echo immediately before TOF repair. These phasic volumes continued to remain elevated after complete surgical repair (Table 1). Trends in RA stroke volumes for all available echos before and after surgery were modeled using a population-averaged model with an exchangeable within-panel correlation structure (Figure 2), showing no statistically significant difference after surgery. But there was statistical significance noted in RA ejection fraction. Please see attached image for statistical analysis and results of the study. Conclusions: The indexed RA phasic volumes in children with TOF are normal initially and increases before TOF repair and it continued to increase after TOF repair. The increase RA phasic volumes suggest RV diastolic dysfunction similar to the findings of LA phasic volumes and left ventricular diastolic dysfunction. Our findings indicate slow worsening RV diastolic function in patients with TOF after surgical repair. RA volume and function can be the novel marker to diagnose and monitor right ventricular diastolic dysfunction.

This is the first study to assess right ventricular myocardial performance using the systolic-to-diastolic duration ratio derived from 2D strain. Seventy-six children with repaired Tetralogy of Fallot were evaluated. Echocardiographic data were correlated with cardiac magnetic resonance and peak oxygen consumption during exercise. The results show the right ventricular myocardial systolic-to-diastolic duration ratio incorporates systolic and diastolic performance, electromechanical dyssynchrony, and postsystolic shortening and is associated with exercise capacity in repaired Tetralogy of Fallot.
