Brief Summary
The aim is to conduct a prospective multi-centre international inception cohort study with an enrollment goal of 3,000 TOF patients and 2 year follow-up post-repair. The proposed sample size and methodology will result in statistically powerful results to allow for evidence-based change to current TOF surgical practices.

Outcome Measures
Primary Outcomes (1)
RV physiology and morphology
To determine the association between baseline morphology, surgical repair technique (various surgical strategies for VSD closure and managing the RVOT), and RV physiology and morphology at 2 years obtained from echocardiogram studies.
2 years post-repair
Secondary Outcomes (7)
Number of patients undergoing various palliation procedures and surgical repair strategies
2 years
Cardiovascular mortality rate
30 days and 2 years after repair
Rate of palliation failure
2 years
Effect of palliation procedures on cardiac morphology
2 years
Post-operative restrictive physiology
2 years
- +2 more secondary outcomes
Study Arms (1)
TOF participants
Tetralogy of fallot patients at any age
Eligibility Criteria
TOF patients of any age undergoing their first cardiac intervention. Please refer to the eligibility criteria for more details.
You may qualify if:
- TOF with RVOT stenosis. TOF is defined as anterio-cephalad deviation of the ventricular outlet septum with no more than 50% aortic override and a single outflow VSD.
- TOF with pulmonary atresia and confluent pulmonary arteries.
- Admitted with intent to treat (i.e. patient planned to undergo a primary or staged repair).
- Patients with coronary artery anomalies, right aortic arch, and 22q11 deletion may be included
You may not qualify if:
- TOF with absent pulmonary valve
- Other major cardiac anomalies such as AVSD, multiple VSDs, right atrial isomerism, and MAPCAs. In this instance, the definition of MAPCAs does not include dilated bronchial collateral arteries.
- Unbalanced ventricles precluding biventricular repair
- Major genetic abnormalities/syndromes e.g. trisomy 13,18, and 21
- Major extra cardiac anomalies e.g. diaphragmatic hernia, omphalocele, absent sternum, cerebral palsy
- Infective endocarditis as an indication for intra-cardiac repair
- Stroke in the last 30 days prior to palliation or intra-cardiac repair
- Known diagnosis of HIV or hepatitis B
- Any previous cardiac procedures
- Patient's circumstance that precludes completion of follow-up telephone call and/or obtaining information from the 2-year cardiology follow-up
