UVRV: Evaluating Right Ventricular (RV) Size and Function Using the Upper Valley RV Algorithm and Novel Imaging Modalities
Study Details
Study Description
Brief Summary
The primary purpose of this study is to evaluate the diagnostic performance of three methods for measuring right ventricular size and function including the Philips Novel RV quantification technologies (RV Heart Model volumetric analysis and Philips 2D strain) and the Upper Valley Right Ventricle Algorithm (UVRV) algorithm as compared to the gold standard of volumetric analysis via cardiac magnetic resonance imaging (CMR) in a broad patient population.

Detailed Description
This is a single-center, blinded, randomized control trial of patients 18-years or older that are undergoing CMR as a standard of care at Dartmouth-Hitchcock Medical Center in Lebanon, NH. After informed consent is obtained, subjects undergo a study-specific external, non-invasive echocardiogram utilizing a special RV focused protocol on the same day of their CMR as close to their scheduled CMR as possible to minimize wait time for consented patients. The echocardiogram takes approximately an additional 30 minutes of the subject's time.
De-identified echocardiogram images from each subject will be evaluated by experienced echocardiographers using three different methodologies (standard method, Phillips Novel technology and the newly developed UVRV algorithm). The methodologies will be compared with each other to determine sensitivity, specificity and accuracy.
