What Researchers Did
Researchers described a case of arterial gas embolism occurring as a delayed complication after Watchman left atrial appendage closure device implantation, treated with HBOT.
What They Found
The patient presented with neurological symptoms hours after the cardiac procedure. HBOT was administered after the diagnosis of arterial gas embolism was made, resulting in neurological improvement.
What This Means for Canadian Patients
Watchman device implantation is increasingly performed in Canadian hospitals. Cardiologists and neurologists should be aware that delayed arterial gas embolism is a possible complication requiring urgent HBOT referral.
Canadian Relevance
Covers an OHIP-covered indication: arterial gas embolism. Ontario patients who develop arterial gas embolism from any cause, including cardiac procedures, may be eligible for publicly funded HBOT.
Study Limitations
A single case report cannot establish the incidence of this complication or generalize treatment outcomes.
