Association with Outcome of the Regurgitant-Volume Adjusted Right Ventricular Ejection Fraction in Secondary Tricuspid Regurgitation.
J Am Soc Echocardiogr

Department of Medicine and Surgery, University of Milano-Bicocca, Milan, Italy; Department of Cardiology, Istituto Auxologico Italiano, IRCCS, Milan, Italy.
Background: In patients with secondary tricuspid regurgitation (STR), right ventricular ejection fraction (RVEF) may not accurately reflect the actual RV systolic performance since a considerable amount of the RV stroke volume (SV) is regurgitated back into the right atrium. To overcome this limitation, we explored the association with the outcome of the effective RVEF (eRVEF), which accounts for the tricuspid regurgitant volume (RegVol).
Methods: 513 patients with STR (mean age 75±13 years, 39% atrial STR, 58% severe) underwent complete two-, three-dimensional, and Doppler echocardiography.
A Mobile Health Intervention to Increase Physical Activity in Pulmonary Arterial Hypertension.
Chest
September 2021
Division of Cardiovascular Medicine and Vanderbilt Translational and Clinical Cardiovascular Research Center, Nashville, TN. Electronic address:
Background: Supervised exercise training improves outcomes in patients with pulmonary arterial hypertension (PAH). The effect of an unsupervised activity intervention has not been tested.
Research Question: Can a text-based mobile health intervention increase step counts in patients with PAH?
Study Design And Methods: We performed a randomized, parallel arm, single-blind clinical trial.
