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.

OrbusNeich to study Combo Stent on heart disease patients

To better study the efficacy of the Combo Bio-engineered Sirolimus Eluting Stent, OrbusNeich has announced that a clinical trial to evaluate the success of the stent is underway in patients with symptomatic, ischemic heart disease.

RSNA: New automated CCTA software may be useful in triaging ED patients

CHICAGONegative results from an automated coronary CT angiography (CCTA) reader may be useful for triaging emergency department (ED) patients, based on a study presented Monday at the Radiological Society of North America (RSNA) conference. Conversely, the researchers determined that positive automated results require further interpretation by an experienced reader.

Echo survey reveals fears of practice changes due to CMS cuts

Initial results of a survey conducted by the American Society of Echocardiography found that 87 percent of cardiologists and cardiovascular ultrasound technicians fear that the 2010 Center for Medicaid & Medicare Services (CMS) Physician Fee Schedule could trigger staff reductions, end their practice or require them to stop accepting Medicare patients.

Spacelabs now offers wireless capabilities for patient monitors

Patient monitoring and connectivity solutions company Spacelabs Healthcare has released a wireless feature for its Ultraview SL2200, SL2400 and SL2600 portable patient monitors.

RSNA: Cardiac CT could replace fluoroscopy for valves w/ less radiation dose

CHICAGOCardiac CT can advantageously replace fluoroscopy for evaluation of bileaflet valves, according to a prospective analysis that confirms recent retrospective studies, presented Sunday at the 2009 Radiological Society of North America (RSNA) meeting.

JACC: For mitral regurgitation, 3D echo passes the litmus test

In a head-to-head comparison with velocity-encoded cardiac MR to measure mitral regurgitation, real-time 3D echocardiography proved feasible and accurate. In addition, researchers found that the currently recommended 2D echo approach significantly underestimated both the effective regurgitant orifice area and the regurgitant volume.

Vital Images tuned for Intel's Xeon processors

Advanced visualization and analysis solutions company Vital Images and computer hardware developer Intel have merged technologies to decrease processing time for large clinical data sets.

Mayo teams with STMicroelectronics for CV patient monitoring system

STMicroelectronics, a semiconductor company, and the Mayo Clinic are collaborating on a new platform for remotely monitoring patients with chronic cardiovascular disease. The platform will seek to monitor person-specific data, physiological parameters, lifestyle influences and treatment choices.
