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.

Pulmonary vein isolation (PVI) using higher power energy ablation was found to be safe, more effective and was able to cut procedure time, but there was a signal of increased emboli.

High power vs. standard RF ablation leads to improved pulmonary vein isolation, shorter procedures

New research, presented at Heart Rhythm 2022, found a 96% percent freedom from reoccurrence of atrial fibrillation in patients treated with high power vs. standard power radiofrequency ablation.

Same-day discharge for AFib ablation a success thanks to telehealth

The new analysis, presented during Heart Rhythm 2022, focused on patients treated at a high-volume facility during the COVID-19 pandemic.

Study urges radiologists to report CAC findings on all chest CTs, regardless of clinical indication

Although current guidelines recommend radiologists evaluate CAC on all non-gated, non-contrast chest CT scans, the authors of the study note that these guidelines are not consistently followed.

STROKE AF study shows insertable cardiac monitors detect 4 times more AFib than Holter monitoring

New data from the STROKE AF clinical trial shows large and small vessel ischemic stroke patients who receive short-term or intermittent monitoring with Holter and 30-day external monitors had fewer AFib episodes detected that continuous implantable cardiac monitors.

Statin reduces risk for non-obstructive CAD patients but no significant risk reduction for aspirin

The results of a study published in Radiology: Cardiothoracic Imagincall into question the value of initiating aspirin therapy in certain instances.

Heartflow FFR-CT allows noninvasive assessment of a patient'c coronary arteries without the need for a diagnostic angiogram.

VIDEO: HeartFlow FFR-CT sees increased interest after inclusion in the 2021 Chest Pain Guidelines

HeartFlow’s non-invasive cardiac computed tomography derived fractional flow reserve (FFR-CT) technology enables FFR values for the entire coronary tree of a patient using just a CT scan. This can show the significance of any coronary plaque lesions and if a patient needs to be sent to the cath lab for revascularization, or if they can be treated medically.

VIDEO: How to implant a Linq implantable cardiac monitor

The Medtronic Linq and Linq II implantable cardiac monitors (ICM) have become some of the most popular ICM devices on the market, partly because they are easy to insert.
