Early and late results in pulmonary atresia

The Annals of Thoracic Surgery
A R Dobell, A Grignon


The early and long-term results following surgical treatment of 24 infants with pulmonary atresia with an intact ventricular septum were reviewed. Pulmonary valvotomy was the operation most often performed, and we came to realize that this was effective when the preoperative right ventricular angiogram had shown an open conus up to the atretic valve. By contrast, no infant without a patent conus survived pulmonary valvotomy. We suggest that this subgroup of patients (8 of the 24 in this series) should have a systemic-pulmonary shunt followed later by reconstruction of the right ventricular outflow tract. Diminutive right ventricles will grow and dilate if a reasonable passageway is formed from right ventricle to pulmonary artery. Thus the long-term results have been excellent when this has been carried out, with normal right ventricular pressures and appearance on angiography in 7 patients followed up to 13 years.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
