Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

Large peridevice leaks after left atrial appendage occlusion (LAAO) are incredibly rare and not associated with a greater risk of adverse outcomes, according to new research published in JACC: Clinical Electrophysiology.[1] Smaller residual links are more common, however, and associated with a risk of thromboembolic and bleeding events.

What peridevice leaks after LAAO mean for patient health

The study's authors reviewed data from more than 50,000 patients, presenting their findings in JACC: Clinical Electrophysiology.
