Resumen

La taquicardia ventricular de las cúspides aórticas es una taquicardia idiopática e infrecuente. Su mecanismo arritmogénico es la actividad desencadenada por posdespolarizaciones tardías. Predomina en jóvenes y su curso es generalmente, benigno. La ablación con radiofrecuencia es un procedimiento eficaz y seguro, se reserva para los pacientes con fracaso a los fármacos antiarrítmicos. Se presenta un paciente masculino, de 24 años de edad, sin cardiopatía estructural y con episodios muy frecuentes de taquicardia ventricular no sostenida. Se realizó ablación exitosa con radiofrecuencia del foco arrítmico ubicado en la cúspide coronariana derecha.
