“…[2] The pulmonary valve morphology in patients with TOF is commonly abnormal, and most data in literature has been obtained from the study of surgical heart specimens during autopsy, which could be biased due to different survival rates of patients with various anatomic variations. Because of the current trends towards valve sparing techniques and native valve cusp augmentation techniques to reduce the incidence of pulmonary regurgitation and its long-term complications following corrective TOF repair,[34] preoperative awareness of pulmonary valve morphology could contribute towards better surgical planning. Multidetector cardiac computed tomography (CT) gives good anatomic detail of the cardia, its vascular structures, and valves.…”

Background:Tetralogy of Fallot (TOF) is a complex congenital heart disease with anatomic variations. Although the pulmonary valve in TOF is abnormal, it has not been studied well, especially on newer imaging modalities such as multidetector computed tomography (CT), which gives excellent anatomic detail.Aims:The aim of this study was to assess the morphology of pulmonary valve in TOF on CT and evaluate its association with the degree of hypoplasia of infundibulum and pulmonary trunk.Materials and Methods:The cardiac CT scans of 30 patients with TOF were reviewed to evaluate the morphology of the pulmonary valve, infundibulum, and pulmonary arteries. Fisher's exact test was performed to examine the association between pulmonary valve morphology and degree of hypoplasia of the infundibulum and pulmonary trunk.Results:16.7% of patients with TOF had pulmonary atresia. The prevalence of tricuspid, bicuspid, and absent valves were 10%, 53.3% and 6.7%, respectively. In another 13.3% of patients, although valve tissue was present, exact morphology could not be determined on CT. The commissures of 62.5% of the bicuspid valves were at 12 o’clock and 6 o’clock or slightly off the midline. There was statistically significant association between valve morphology and degree of infundibular hypoplasia (P < 0.001) and calibre of pulmonary trunk (P < 0.001).Conclusion:Morphological abnormality of the pulmonary valve is common in TOF. The most common type of pulmonary valve in TOF patients is bicuspid valve with commissures at 12 o’clock and 6 o’clock or slightly off the midline. Fewer cusps of the pulmonary valve are associated with a more severe degree of pulmonary artery hypoplasia.

“…The TA-TP approach has resulted in significantly less RV dilatation and better preservation of contractility at 10 years follow up. [2930] Since the description of the pulmonary cusp augmentation technique by Sung and associates[31] in 2003, we have adopted this technique for most patients requiring a transannular patch.…”

“…When the commissures are located at the 6 and 12 o'clock positions or the commissures are anterior and posterior but located off the midline, we divide the pulmonary valve at or near the anterior commissure to preserve as much valve tissue as possible, as described by Sung et al . [31] The division of the remaining obstructing muscular and fibrous bands is performed through the ventriculotomy. The VSD is closed through the TV.…”

Tetralogy of Fallot (TOF) is an important lesion for all pediatric and congenital heart surgeons. In designing the most appropriate operation for children with TOF, the postoperative physiology should be taken into account, both in the short and long term. The balance between pulmonary stenosis (PS) and pulmonary insufficiency (PI) may be critical for preservation of ventricular function. A unified repair strategy that limits both residual PS and PI is presented, along with supporting experimental evidence, a strategy for dealing with coronary anomalies, and comments regarding best timing of operation.
