Tip Detection Method With New IVUS-Based 3D Wiring Facilitates CTO Percutaneous Coronary Intervention

A tip detection method using a newly developed intravascular ultrasound-based three-dimensional wiring was found to superior to conventional method for chronic total occlusion-percutaneous coronary intervention.

Detecting Ischemia in Myocardial Bridging With CT Angiography-Derived FFR

Computed tomography angiography-derived fractional flow reserve demonstrated high diagnostic performance for identifying functional ischemia in vessels with myocardial bridging.

Optical Coherence Tomography Superior to Intravascular Ultrasound in Lesion Assessment

Optical computed tomography has better accuracy than intravascular ultraound in detecting hemodynamically significant stenoses.

Imaging Rates Continue to Rise Despite Efforts to Reduce

Despite initiatives to reduce the use of medical imaging, rates continue to rise in both the United States and Ontario, Canada.

Angiography-Derived Fractional Flow Reserve Improves Coronary Lesion Assessment

Fractional flow reserve derived from routine coronary angiography may improve coronary lesion assessment.

Anemia Identified as Risk Factor for Contrast-Induced Acute Kidney Injury

Anemia with a baseline hemoglobin <13 g/dL was associated with a more than 5-fold increased risk for contrast-induced acute kidney injury in patients undergoing coronary angiography.

Chronic Total Occlusions on CCTA Increase Major Adverse Cardiac Event Risk

A significantly higher rate of adverse cardiac events was observed in chronic total occlusions compared with moderate to severe coronary artery disease.

Handheld, Wireless Ultrasound Device SONON 300L Now Available

The device is indicated for ultrasound echo imaging, measurement, and analysis of the human body for general clinical applications including musculoskeletal, vascular, small parts (breast, thyroid), and lung imaging.

CAD Testing, Treatment Changes After Malpractice Damage Caps

There was a decrease in invasive testing as first diagnostic test and fewer patients were referred for angiography after stress test.

Composite Echo Score Predicts PH in Interstitial Lung Disease

The variables for the stepwise echocardiographic score included right ventricular systolic pressure, early pulmonary regurgitation gradient, right atrial area size, tricuspid regurgitation velocity, left ventricle eccentricity index, and right ventricle fractional area change.
