Abstract
TEJEDA-CAMARGO, Miguel J.; ARROYO, Alonso; TAPIAS, Carlos and RODRIGUEZ, Diego. Nodal re-entry in patient with persistent left superior vena cava and absent right superior vena cava. Rev. Colomb. Cardiol. [online]. 2020, vol.27, n.5, pp.469-472. Epub July 28, 2021. ISSN 0120-5633. https://doi.org/10.1016/j.rccar.2019.08.004.
Nodal re-entrant tachycardia is the most common arrhythmia among the paroxysmal atrioventricular tachycardias, with the slow-fast variant being the most common. In many cases, the ablation of the slow pathway is the definitive treatment in many cases, often with a high rate of success and low frequency of complications. The presence of a left superior vena cava and the absence of a right superior vena cava with systematic venous drainage above the coronary sinus is a rare congenital malformation that leads to anatomical anomalies. These make it difficult to use the traditional approach for the ablation of this arrhythmia. The case is presented of a patient with this condition in which the ablation was successful using intracardiac echocardiography and three-dimensional reconstruction.
