Panoulas VF, Keramida K, Boletti O, Papafaklis MI, Flessas D, Petropoulou M, Nihoyannopoulos Pet al., 2017, Association between fractional flow reserve, instantaneous wave free ratio and dobutamine stress echocardiography in patients with stable coronary artery disease., EuroIntervention

AIMS: The association between fractional flow reserve (FFR) and dobutamine stress echocardiography (DSE) in real world stable angina patients is scant and controversial whereas no such comparison exists with instantaneous wave free ratio (iFR). The current retrospective study aimed to investigate the associations amongst these modalities in patients with stable coronary artery disease (CAD) and intermediate coronary lesions. METHODS AND RESULTS: We studied 62 consecutive stable angina patients who underwent DSE and subsequently coronary angiography with FFR (in all 62) and iFR (in 46/62 patients) assessment of intermediate single vessel lesions between 2014-2015. Using receiver-operating curves (ROC) we sought to identify the optimal FFR and iFR cut off points with the highest discriminative power to predict DSE result. Kappa coefficient was used to assess the agreement between FFR, iFR and DSE. Mean age of the study cohort was 63.5±12 years and 35 (56.5%) were males. Thirteen (21%) lesions were adjudicated as causing reversible ischemia on DSE. Using ROC (FFR predicting DSE result), the area under the curve was 0.952 (95% CI: 0.902 to 1), whereas for iFR was 0.743 (95%CI 0.560 to 0.927), p AUC comparison=0.03. Optimal FFR cut-off point predicting positive DSE was 0.80. There was a strong agreement between DSE and FFR (Kappa 0.682, p<0.001). There was only modest agreement between iFR and DSE (kappa 0.258, p=0.068) using a cut-off value of 0.9. CONCLUSIONS: In patients referred for evaluation of stable CAD, there was good agreement between DSE and FFR (87%) but less so with iFR (71.7%).

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.
