title: [Agenesis of the right superior vena cava associated with total heart block].
abstract: The superior left vena cava with the absent superior vena cava is a rare abnormality, especially when associated with total heart block. We report a case of a patient in which the presence of superior left vena cava and the absence of the superior vena cava was detected during the implantation of a pacemaker for the correction of a total heart block, which led us to use a different technique for the fixation of the ventricular electrode. To confirm the supposed absence, several image exams were made showing the difficulty on the diagnosis of the described syndrome.
