Abstract

When corrective surgery for tetralogy of Fallot was accomplished through the use of a transannular GORE-TEX® patch with a pericardial unicusp, the right-ventricular end-diastolic volumes of all patients studied within a year of the surgery were within the normal ranges because of decreased pulmonary valve regurgitation. The right-ventricular ejection fraction was also only slightly depressed, indicating preservation of right-ventricular function. All patients were noted to maintain normal stroke volumes and normal systolic indices.

In contrast, the patients who had transannular patches placed without unicusps showed significantly elevated right-ventricular end-diastolic volumes and lower right-ventricular ejection fractions. These resulted from markedly dilated right-ventricular outflow regions in conjunction with enlarged right-ventricular chambers, which manifested as large dyskinetic areas in the anterior right-ventricular walls.
