Practical Aspects of Patent Foramen Ovale Closure: Ultrasound and Fluoroscopic Guidance.

Percutaneous PFO closure is a well-established medical procedure to mitigate paradoxic embolism and the future risk of stroke in a well-selected patient clientele. When it comes to procedural guidance during PFO closure, various modalities exist, each with its own advantages and disadvantages. Guidance by transesophageal echocardiography (in combination with fluoroscopy) offers high-resolution 2D/3D imaging, however, it requires the presence of a peri-interventional imager and conscious sedation (or endotracheal intubation). Intracardiac echocardiography and fluoroscopy guidance can be performed by a single operator and omits the need for conscious sedation (or endotracheal intubation).
