Introduction: Treatment and diagnosis advances in congenital heart disease are dependent on the improvement of anatomic imaging. Images obtained with 3D computerized tomography, magnetic resonance and echocardiography have helped, but they cannot determine precise haemodynamic parameters. 3D-rotational angiography (3DRA) is a new 3D computerized imaging method used in the catheterization laboratories, and has proved to be an important tool in neurologic and urologic procedures. Objectives: Assess of the use and benefits of 3D-RA in congenital heart disease. Material and Methods: A total of 34 congenital heart disease patients with mean age of 8,96 ± 9,11 years, and mean weight of 24,94±14,44 kg underwent hemodynamics study and subsequent 3D-RA examination using Philips Allure FD10 equipment and low osmolarity contrast injection. Results: A total of 43 3D-RA injections was performed with 80% of success in obtain a clear 3D image. Mean of contrast used in 3D-RA acquisition was 2,41±1,10 ml/kg and total exam contrast was 5,27±2,29 ml/kg. Mean KV was 88,72±15,63 , mAs of 476±165 , and ms of 7,8±1,4 . Air Kerna from 3D-RA injection was 40,48±22,36 mS and Dose-Air Product was 501,47±1172,70 mS.cm². There was no statistically significant difference between regular and 3D-RA injections. Conclusions: Improvement is needed. Although larger contrast volume being used in 3D-RA than CT and regular haemodynamics study, less radiation was used compared with CT. This new method could help in the treatment and diagnosis of congenital heart disease.
