MALKUN, Celin; LIEVANO, John; ISAAC, Oscar  e  MORALES, Jorge. Use of intracardiac echocardiography for percutaneous closure of patent foramen ovale. Rev. Colomb. Cardiol. [online]. 2013, vol.20, n.2, pp.88-93. ISSN 0120-5633.

Objective: to determine the utility of intracardiac echocardiography to assist in the implantation of the device for percutaneous closure of patent foramen ovale. Material and methods: we report the case of a 38 years old male patient with a history of transient cerebral ischemia diagnosed a year earlier, who presented a clinical picture of ischemic cryptogenic stroke. A transesophageal echocardiogram showed a patent foramen ovale. He was scheduled for percutaneous closure of the patent foramen ovale with Amplatzer closure device, and the procedure was programmed with intracardiac echocardiography probe through AcuNav to guide the placement of the Amplatzer, along with the traditional TEE required in these cases. Results: we performed foramen ovale closure using the accepted technique, guided by intracardiac echocardiography and verified by angiography and transesophageal echocardiography. We obtained images of cardiac anatomy using intracardiac echocardiography in real time without interference, which made possible the implant of the device quickly and appropriately. Proper implementation was confirmed by angiography and transesophageal echocardiography. In this case, the procedure of percutaneous closure with Amplatzer device was successful, fast and without complications. Conclusions: intracardiac echocardiography is useful to guide the implantation of devices for closure of patent foramen ovale as well as in cases of atrial septal defect. This technique is easy and safe. The introduction of intracardiac echocardiography catheter, its handling and positioning in the right atrium were quick and easy. Adequate images were obtained with a good identification of the structures of the septum that allowed the successful closure of the foramen ovale with Amplatzer device. According to this research, the literature does not report intracardiac echocardiography as an assistance to guide this procedure, so that we believe this may be the first case performed in Colombia. Moreover, it is necessary a more widespread use of intracardiac catheter for intracavitary echocardiography and implement it instead of transesophageal echocardiography as guide for closure of atrial septal defect and patent foramen ovale. It is convenient to carry out more studies to better assess this assistance which may eliminate the need of transesophageal echocardiography in these patients and in turn the requirement of general anesthesia for these procedures.
