Background: Pulmonary atresia is a congenital heart defect that results from failure in the formation of the pulmonary valve that leads to right ventricular outflow obstruction, preventing the right heart ejection of blood to the lungs. It is also associated with a high incidence of chromosomal anomalies. Methods: A retrospective study of all infants diagnosed with pulmonary in Bahrain was undertaken. Pulmonary atresia was classified into pulmonary atresia with intact ventricular septum, pulmonary atresia in Tetralogy of Fallot, and pulmonary atresia in complex cyanotic heart defects. Short-term outcomes, survival, and associated genetics were analyzed. Results: 84 patients were diagnosed. 57 (67.9%) were males and 27 (32.1%) were females (p = 0.204). The median age at diagnosis was 25 days. Patients diagnosed with pulmonary atresia and complex cyanotic heart defects had the highest early survival rate. The early survival rate of patients diagnosed with pulmonary atresia with intact ventricular septum was lowest (p = 0.0179). Twenty-two patients (26.19%) had chromosomal anomalies. The DiGeorge syndrome was found in 18 patients, and 2 with Down Syndrome and other dysmorphisms in 2. 19 (86.36%) with chromosomal anomalies had pulmonary atresia and Tetralogy of Fallot, and 3(13.64%) with pulmonary atresia and complex cyanotic heart defects (p = 0.027). Conclusions: Pulmonary atresia is a rare but serious congenital heart defect. The lowest short-term survival is in those with intact intraventricular septum. There is a high incidence of chromosomal deletion of 22q11 leading to DiGeorge syndrome in those with Tetralogy of Fallot with pulmonary atresia. Early catheterization and surgical techniques are effective palliation for short-term survival. [ABSTRACT FROM AUTHOR] |
