Transthoracic Echocardiography Evaluation of RV

Transthoracic echoes were acquired using commercial equipment (General Electric Vivid-7, Siemens SC2000 [Malvern, PA]). Echo included evaluation of the RV from the parasternal long and short axis and RV focused apical 4-chamber views, as specified in consensus ASE guidelines.[3 (link)]

Echocardiography Assessment of Myocardial Viability

Check if the same lab product or an alternative is used in the 5 most similar protocols
Every patient underwent echocardiography within 24 h before intervention, based on the recommendation of the American Society of Echocardiography [11 (link), 12 (link)]. The echocardiographic examination was accomplished using General Electric Vivid 7 (Norway) and Siemens Acuson NC 1000 (Germany) machines, using 2 to 2.5 MHZ transthoracic transducers. Echocardiograms were performed in the supine and/or left lateral position. Modified biplane Simpson’s method was used to assess LVEF [11 (link)].Patients with impaired LVEF and without significant angina and/or new crescendo angina underwent low-dose dobutamine stress echocardiography (DSE) for assessment of contractile reserve. Hypokinetic or akinetic myocardial segments that showed improved contractility with low-dose DSE were considered viable [12 (link)].

Contrast-Enhanced Transthoracic Echocardiography

Check if the same lab product or an alternative is used in the 5 most similar protocols
Transthoracic echoes were performed by experienced sonographers using commercial equipment (General Electric Vivid-7, Siemens SC2000 [Malvern, PA]). Images were acquired in long- and short-axis orientations concordant with American Society of Echocardiography guidelines (7 (link)). Following non-contrast imaging, an echo contrast agent (DEFINITY; Lantheus Medical Imaging) was infused via the diluted bolus technique in accordance with manufacturer guidelines. Sonographers then repeated imaging so as to acquire non-contrast and contrast echo images in matching orientations.

Echocardiographic Estimation of Pulmonary Pressure

Check if the same lab product or an alternative is used in the 5 most similar protocols
Transthoracic 2D echocardiograms were acquired using commercially available equipment (General Electric Vivid-7 [Milwaukee, WI], Siemens SC2000 [Malvern, PA], Philips ie33 [Andover, MA]). Pulmonary artery systolic pressure (PASP) was calculated using the modified Bernoulli equation (4 [peak tricuspid regurgitant velocity]2 + right atrial pressure), for which tricuspid regurgitant peak velocity was measured via Doppler and right atrial pressure determined based on size and collapsibility of the inferior vena cava [18 ].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
