Overview

Stroke care has advanced dramatically in recent years, allowing an ever-increasing number of patients to survive and thrive after a stroke.¹ However, this post-stroke population remains at high risk of recurrence. A right-to-left shunt (RLS) is known to be a risk factor for stroke as it provides a conduit for a venous clot to travel to the brain. The current standard of care for RLS detection is to perform a transthoracic echocardiography (TTE) exam. TTE is widely available, but an imperfect screener for RLS due to its low sensitivity (45% SEN, 99% SPE).² In a recent clinical trial, the NovaGuide™ Intelligent Ultrasound demonstrated significant improvement in RLS detection compared to current standard of care.³
