Practitioner-Guided Note
When PFO suspicion remains high despite a negative TEE, order a transcranial Doppler ultrasound with bubble contrast. For medical management, prioritize antiplatelet therapy over warfarin unless superficial or cortical infarcts coexist. When choosing an intervention, opt for an Amplatzer PFO occluder over other devices, keeping in mind that closure benefits are strictly limited to high-risk PFO anatomies.
Key Takeaways
Transthoracic echocardiograms catch only about half of all patent foramen ovales.
Transcranial Doppler ultrasound with bubble contrast effectively detects right-to-left shunting.
PFO closure significantly reduces recurrent strokes specifically for high-risk anatomical shunts.
High-risk PFO is defined by a large shunt paired with an atrial septal aneurysm.
