Replying to @Denise A bubble study is basically an ultrasound trick where we inject tiny microbubbles into your IV to watch how blood flows through your heart. If the bubbles sneak across to the wrong side, it means there’s a hole—like a PFO or ASD—letting blood slip through the shortcut. #cardiology #echocardiography #doctorlife #medicaleducation #hearthealth | Zachary Meade
