Abstract
BACKGROUND
Tetralogy of Fallot with an absent pulmonary valve is a very rare variant of tetralogy. It is characterized by absent valve tissue, severe pulmonary regurgitation, and secondary aneurysmal dilatation of the pulmonary arteries.
AIM
In this study, we aim to investigate the clinical presentations, management strategies, and outcomes of patients with tetralogy of Fallot and absent pulmonary valve.
METHODOLOGY
We retrospectively reviewed the charts of all patients who presented to the American University of Beirut Medical Center between January 2010 and December 2020 and who were diagnosed with this anomaly.
RESULTS
A total of 300 cases of tetralogy of Fallot were identified, of which 18 patients had absent pulmonary valves. They were followed up for an average of 8.2 years. Prenatal diagnoses were made in four patients, while 13 patients were identified in the neonatal period, with an average age of 4.5 days. Genetic testing confirmed DiGeorge syndrome in one patient. Five patients underwent surgical intervention in the neonatal period, while the remaining patients were operated on during their early childhood. While overall there were no surgical mortalities nor any need for reinterventions, a variety of morbidities were encountered.
CONCLUSION
This study provides an overview of this rare anomaly and its management in a developing country.
