Estudio electrofisiológico con mínima escopia en gestante. Minimizando riesgos

Supraventricular tachycardias in pregnant affect the mother and the fetus too, being the pregnancy itself the principal conditioner for pharmacological treatment. In recurrent cases, ablation is an alternative, even more if are performed without fluoroscopy.

We report the case of a 31-week pregnant woman who undergoing to electrophysiological study assisted by a non-fluoroscopic navigation system, with recurrent tachycardias despite treatment. During the study, the presence of a left concealed accessory pathway is verified, and it's mapping and ablationed by retroaortic acces successfully, with only 6 seconds of fluoroscopy to avoid injury in the aortic arch. This case highlights the use of 3D navigation system to perform procedures zero or minimal fluoroscopy.
