Cardiovasc Ultrasound 2018 Nov 19;16(1):30. Epub 2018 Nov 19.

Department of Echocardiography, Shanghai Institute of Medical Imaging; Shanghai Institute of Cardiovascular Diseases, Zhongshan Hospital, Fudan University, 180 Fenglin Road, Shanghai, 200032, China.

Background: In patients with left ventricular (LV) dysssynchrony, contraction that doesn't fall into ejection period (LVEj) results in a waste of energy due to inappropriate contraction timing, which was now widely treated by cardiac resynchronization therapy(CRT). Myocardial Contraction Efficiency was defined as the ratio of Efficient Contraction Time (ECTR) and amplitude of efficient contraction (ECR) during LVEj against that in the entire cardiac cycle. This study prospectively investigated whether efficiency indexes could predict CRT outcome. Read More

Performing SE during physical exercise is challenging due to a suboptimal patient position and vigorous movements of the patient's chest. This hampers a stable ultrasound position and reduces the diagnostic performance of SE. Read More

Cardiac fluid dynamics meets deformation imaging.

Cardiovasc Ultrasound 2018 Feb 20;16(1). Epub 2018 Feb 20.

Department of Engineering and Architecture, University of Trieste, P.le Europa 1, 34127, Trieste, Italy.

Cardiac function is about creating and sustaining blood in motion. This is achieved through a proper sequence of myocardial deformation whose final goal is that of creating flow. Deformation imaging provided valuable contributions to understanding cardiac mechanics; more recently, several studies evidenced the existence of an intimate relationship between cardiac function and intra-ventricular fluid dynamics.

Equivocal tests after contrast stress-echocardiography compared with invasive coronary angiography or with CT angiography: CT calcium score in mildly positive tests may spare unnecessary coronary angiograms.

Cardiovasc Ultrasound 2018 Feb 6;16(1). Epub 2018 Feb 6.

Department of Cardiology, Parma University Hospital, Via Gramsci 14, 43123, Parma, Italy.

Background: Imaging stress tests are not ideally accurate to predict anatomically obstructive CAD, leading to a non-trivial rate of unnecessary iCA. This may depend on the threshold used to indicate iCA, and maybe CTA or, one step earlier, CT calcium score could spare most unnecessary iCA in only mildly positive cSE. We assessed the diagnostic accuracy of contrast stress-echocardiography (cSE) in comparison with invasive coronary angiography (iCA), and CT angiography (CTA) only in case of equivocal tests, to find hints helping reduce falsely positive cSE in the suspicion of coronary artery disease (CAD).

Comparison of strain parameters in dyssynchronous heart failure between speckle tracking echocardiography vendor systems.

Cardiovasc Ultrasound 2017 Oct 18;15(1):25. Epub 2017 Oct 18.

Department of Cardiology, University Medical Centre Utrecht, P.O. Box 855500, 3508, GA, Utrecht, The Netherlands.

Background: Although mechanical dyssynchrony parameters derived by speckle tracking echocardiography (STE) may predict response to cardiac resynchronization therapy (CRT), comparability of parameters derived with different STE vendors is unknown.

Methods: In the MARC study, echocardiographic images of heart failure patients obtained before CRT implantation were prospectively analysed with vendor specific STE software (GE EchoPac and Philips QLAB) and vendor-independent software (TomTec 2DCPA). Response was defined as change in left ventricular (LV) end-systolic volume between examination before and six-months after CRT implantation. Read More
