Digital subtraction angiography in the preoperative diagnosis of congenital heart disease.
From December of 1986 through February of 1990, digital subtraction angiography was performed on 156 patients, and specific diagnoses of congenital heart disease were made on the basis of information gathered by this imaging technique, supplemented by the physical examination. No other imaging techniques were used, for this was a prospective study designed to determine the accuracy of digital subtraction angiography alone in the diagnosis of congenital heart disease. When 80 of these 156 patients underwent subsequent operation, 75 were shown to have been diagnosed correctly, for an accuracy rate of 93.75%. Two patients died, for a mortality rate of 2.5%. The diagnostic value of digital subtraction angiography is discussed, as well as the compensative management of its artifacts.
