Tetralogía de Fallot: hallazgos tomográficos antes y después de la cirugía.

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease; its clinical manifestations vary depending on the degree of obstruction of the right ventricular outflow tract and its hemodynamic repercussion. Surgical treatment may be complete repair or palliative depending on the patient's condition. Doppler color echocardiogram is the diagnostic method of choice; however, angiotomography has recently become a useful tool for diagnosis and postoperative monitoring. Objective: review the specialized literature on diagnostic criteria for Tetralogy of Fallot and discuss the principal postoperative findings in computed angiotomography. Material and methods: exhaustive review of the specialized literature and selection of representative cases of patients with diagnosis of tetralogy of Fallot (with computed angiotomography) at Instituto Nacional de Cardiologia Ignacio Chavez. Conclusion: computed angiotomography has emerged as an additional tool for diagnosis and postoperative monitoring of patients with tetralogy of Fallot, especially in patients with inconclusive echocardiograms, in whom it is preferable to avoid the sedation required for evaluation by magnetic resonance. The radiologist must be familiar with the key signs for diagnosis of tetralogy of Fallot and for monitoring palliative or definitive surgical treatment. [ABSTRACT FROM AUTHOR]
