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.

The Medtronic SelectSecure MRI SureScan Model 3830 cardiac lead already gained FDA approval for His-Bundle pacing back in 2018. Now, the lead is also approved for left bundle branch area pacing, providing users with another option when treating patients for bradycardia. According to Medtronic, this marks the first time the FDA has approved a device for this indication.

An updated look at how cognitive impairment affects TAVR outcomes

The connection between cognitive impairment and postoperative delirium among TAVR patients stood out as a definite concern to the study's authors.

CT has been used for planning and procedural guidance in pulmonary vein isolation (PVI) for about 20 years. It shows the anatomy to the electrophysiologist. The EPs also can load the imaging into their EP mapping system. It also shows them the location of the esophagus and the phrenic nerve so they can avoid these during the procedures. #PVI #EPeeps
