Rehman MB, Howard LS, Christiaens LP, Gill D, Gibbs JSR, Nihoyannopoulos Pet al., 2017, Resting right ventricular function is associated with exercise performance in PAH, but not in CTEPH., Eur Heart J Cardiovasc Imaging

Aims: To assess whether resting right ventricular (RV) function assessed by Global RV longitudinal strain (RVLS) and RV fractional area change (FAC) is associated with exercise performance in pulmonary arterial hypertension (PAH) and in chronic thromboembolic pulmonary hypertension (CTEPH). Methods and results: We prospectively recruited 46 consecutive patients with PAH and 42 patients with CTEPH who were referred for cardio-pulmonary exercise testing (CPET) and transthoracic echocardiography. Resting RV systolic function was assessed with RVLS and FAC. CPET parameters analyzed were percentage of predicted maximal oxygen consumption (VO2max) and the slope of ventilation against carbon dioxide production (VE/VCO2). Spearman correlation was performed between echocardiographic measurements and CPET measurements. In PAH, spearman correlation found an association between RVLS and VE/VCO2 (coefficient = 0.556, P < 0.001) and percentage predicted VO2max (coefficient = -0.393, P = 0.007), while FAC was associated with VE/VCO2 (coefficient = -0.481, P = 0.001) and percentage of predicted VO2max (coefficient = 0.356, P = 0.015). Conversely, in CTEPH, resting RV function was neither associated with percentage of predicted VO2max nor with VE/VCO2, whether assessed by RVLS or FAC. Conclusion: In PAH, resting RV function as assessed by FAC or RVLS is associated with exercise performance and could therefore make a significant contribution to non-invasive assessment in PAH patients. This association is not found in CTEPH, suggesting a disconnection between resting RV function and exercise performance, with implications for the use of exercise measurements as a prognostic marker and clinical/research endpoint in CTEPH.

Transcatheter aortic valve implantation (TAVI) is currently the treatment of choice for patients with severe aortic stenosis (AS) who are unsuitable for surgical aortic valve replacement (SAVR), and is an acceptable alternative for those at high and intermediate surgical risk. In published TAVI registries and meta-analyses, whilst women are significantly older they present with fewer comorbidities compared to men (including coronary artery disease, peripheral vascular disease, diabetes and chronic obstructive pulmonary disease). In response to chronic pressure overload from AS, women have been shown to develop greater levels of left ventricular hypertrophy than men, as well as having a greater preservation of LV ejection fraction (LVEF) and less fibrosis. Following aortic valve replacement, women have been shown to have a faster regression of myocardial hypertrophy, with a significant improvement in LVEF. Following TAVI, female gender seems to be associated with a significantly lower one-year mortality. In the current viewpoint, it is discussed whether these findings reflect a true differential treatment response to TAVI among women, or simply the higher comorbidity burden among males undergoing TAVI.

The introduction of portable, pocket-sized echocardiography devices in various healthcare systems has raised new questions with regards to their realistic use in clinical practice. Several studies have already attempted to provide information regarding their safety and diagnostic potential, the training required to operate them, as well as their direct comparison with standard echocardiography machines. This manuscript is a review of the literature of the documents or position papers which employ the use of pocket or handheld devices. Following review of the literature, we suggest that these miniaturized devices can provide a valuable diagnostic tool that can complement and improve the diagnostic yield of clinical examination. When operated by appropriately trained professionals, they can provide a limited but very reliable echocardiographic assessment. Pocket-sized echocardiography is a part of physical examination and should not be considered a complete echocardiographic scan. Optimal training is required for the smooth operation of handheld echocardiography.
