Abstract

Since the first description of Tetralogy of Fallot (ToF) in 1671 by Niels Stensen and in 1888 by Étienne-Louis Arthur Fallot, numerous papers have reported on this anomaly, along with its variants and concomitant cardiovascular anomalies. Aberrant right subclavian artery (ARSA) is the most common anomaly of the aortic arch. Different from the left aberrant subclavian artery, occurrence of ARSA in ToF-patients has only casuistically been reported so far. The present study reports on two ToF-patients with ARSA. It is important to note that knowledge of the coexistence of both anomalies has highly practical points during surgical or endovascular corrections of congenital heart defects (including ToF).

Desde a primeira descrição da tetralogia de Fallot (ToF) em 1671 por Niels Stensen e em 1888 por Étienne-Louis Arthur Fallot, vários trabalhos relataram essa anomalia juntamente com suas variantes e anomalias cardiovasculares concomitantes. A artéria subclávia direita aberrante (ASDA) é a anomalia do arco aórtico mais comum. Diferentemente da artéria subclávia esquerda aberrante, a ocorrência de ASDA em pacientes com ToF só foi relatada casuisticamente. Apresentamos dois pacientes de ToF com ASDA. É importante notar que o conhecimento da coexistência das duas anomalias tem pontos muito práticos durante correções endovasculares ou cirúrgicas de defeitos cardíacos congênitos (inclusive ToF).
