Background
Patients 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.

Background
Anomalous origin of the left coronary artery from the pulmonary trunk is rare, occurring at an incidence of 1 in 300 000. If not diagnosed and treated early, it is life-threatening. Children with the anomaly usually present in infancy with congestive cardiac failure, and are occasionally referred for cardiac transplant. We investigated the medium term outcome for patients following creation of a two-coronary arterial circulation.
MethodsBetween 1992 and 2007, we diagnosed 15 patients seen at our Institution as having anomalous origin of the left coronary artery from the pulmonary trunk. Over a period of 13 years, aortic reimplantation was undertaken in 12 of these patients, who form the studied cohort.
ResultsDirect reimplantation was performed in 5 patients. In 3 cases, a tension-free anastomosis was created using a caudally based flap. In another 3 cases, an extended flap was used, while a patch arterioplasty was fashioned in the final patient. There were no deaths. Left ventricular function recovered in all but one of the patients, and all patients had a reduction in the degree of mitral regurgitation.
ConclusionsAmong the variety of surgical techniques, transfer of the anomalous left coronary artery to the aorta is the ideal method for long-term patency and adequate blood supply. This can be achieved by creating flaps based on the walls of the pulmonary trunk and aorta, producing a dual coronary arterial supply with no mortality and low morbidity.
