Right ventricular failure (RVF) is associated with significant morbidity after left ventricular assist device (LVAD) surgery. Hemodynamic, clinical, and 2-dimensional echocardiographic variables poorly discriminate patients at risk of RVF. We examined the utility of 3-dimensional echocardiography (3DE) right ventricular (RV) volumetric assessment to identify patients at risk for RVF. ⋯ Quantitative 3DE is a promising method for pre-LVAD RV assessment. RV volumes assessed by 3DE are predictive of RVF in LVAD recipients independently from hemodynamic correlates of RV function.

Randomized Controlled Trial Multicenter Study
Heart failure and respiratory hospitalizations are reduced in patients with heart failure and chronic obstructive pulmonary disease with the use of an implantable pulmonary artery pressure monitoring device.
Chronic obstructive pulmonary disease (COPD) is a frequent comorbidity in patients with heart failure (HF). Elevated pulmonary arterial (PA) pressure can be seen in both conditions and has been shown to predict morbidity and mortality. ⋯ HF management incorporating hemodynamic information from an implantable PA pressure monitor significantly reduces HF and respiratory hospitalizations in HF subjects with comorbid COPD compared with standard care.
