Validation of stroke volume and cardiac output by electrical interrogation of the brachial artery in normals: assessment of strengths, limitations, and sources of error
Abstract The goal of this study is to validate a new, continuous, noninvasive stroke volume (SV) method, known as transbrachial electrical bioimpedance velocimetry (TBEV). TBEV SV was compared to SV obtained by cardiac magnetic resonance imaging (cMRI) in normal humans devoid of clinically apparent heart disease. Thirty-two (32) volunteers were enrolled in the study. Each subject was evaluated by echocardiography to assure that no aortic or mitral valve disease was present. Subsequently, each subject underwent electrical interrogation of the brachial artery by means of a high frequency, low amplitude alternating c...

The association of ankle‐brachial index with silent cerebral small vessel disease: results of the Atahualpa Project
ConclusionsIn this population‐based study conducted in rural Ecuador, apparently healthy individuals aged ≥60 years with ankle‐brachial index values ≤0·90 and ≥1·4 are almost four times more likely to have a silent lacunar infarct. Ankle‐brachial index screening might allow recognition of asymptomatic people who need further investigation and preventive therapy.

Coronary Artery Calcification, Intima-Media Thickness, and Ankle-Brachial Index Are Complementary Stroke Predictors Clinical Sciences
Conclusions— CAC, CIMT, and ABI provide complementary information about stroke risk. ABI, which is distinctive in a small subpopulation, had the highest and CIMT, which is distributed across a larger range of values, had the lowest predictive value.

Characterization of dysfunctional remote myocardium in left ventricular anterior aneurysms and improvements following surgical ventricular restoration using cardiac magnetic resonance imaging: preliminary results
CONCLUSIONS In patients with chronic ischaemic heart disease with LV aneurysms/large areas of scar, improvements in the remote myocardial MMV and WT underline LV systolic function improvements after SVR. The persistence of myocardial WT in early diastole is the likely mechanism for incomplete or absence of relief of LV diastolic dysfunction by SVR.

Diagnostic Accuracy and Risk Factors of the Different Lacunar Syndromes
Conclusions: The clinical diagnosis of patients with lacunar syndromes is inaccurate, especially among patients with sensorimotor syndrome. DWI is mandatory for obtaining an accurate diagnosis of the infarct.

Comparison of Echocardiographic and Pressure–volume Loop Indices of Systolic Function in Patients with Single Ventricle Physiology: A Preliminary Report
ConclusionsObtaining PVLs via microconductance catheters can reliably be performed in the single ventricle population and serve as a method to validate echocardiographic indices in this high‐risk population. Of the echocardiographic variables, FAC showed the best correlation with PVL indices. Future studies controlling for stage of palliation should be performed to further validate echocardiographic measures of systolic function in this patient population.

Left ventricular diastolic dysfunction is associated with cerebral white matter lesions (leukoaraiosis) in elderly patients without ischemic heart disease and stroke
ConclusionsThis investigation identified an association between LV diastolic dysfunction and WML. Further investigations are required to clarify whether there is a direct association between the two diseases. Geriatr Gerontol Int 2014; 14 (Suppl. 2): 71–76.

Sildenafil Improves Exercise Hemodynamics in Fontan Patients Congenital Heart Disease
Conclusions— In Fontan patients, sildenafil improved cardiac index during exercise with a decrease in total pulmonary resistance index and an increase in stroke volume index. This implies that pulmonary vasculature represents a physiological limitation, which can be attenuated by sildenafil, the clinical significance of which warrants further study.

Imaging Characteristics of Ischemic Strokes Related to Patent Foramen Ovale Clinical Sciences
Conclusions— A PFO-stroke usually appears as a single cortical or multiple small ischemic lesions in the vertebrobasilar circulation without any visible vessel occlusion on angiography. The recanalization rate is significantly lower than in AF-stroke. These imaging characteristics of PFO-stroke may help to diagnose the mechanism and determine the treatment strategy.

Aortic Valve Area, Stroke Volume, Left Ventricular Hypertrophy, Remodeling, and Fibrosis in Aortic Stenosis Assessed by Cardiac Magnetic Resonance Imaging: Comparison Between High and Low Gradient and Normal and Low Flow Aortic Stenosis Valvular Heart Disease
Conclusions— CMR confirmed overall accuracy of echocardiographic classification of AS but demonstrated that LG/LF and LG/NF AS have larger AVA, less LV hypertrophy, and similar focal fibrosis compared with HG/LF AS. This challenges the view that LG/LF AS is a more advanced state of AS.

Clopidogrel Use Is Associated With an Increased Prevalence of Cerebral Microbleeds in a Stroke-Free Population: The Rotterdam Study Stroke
Conclusions In stroke-free individuals, clopidogrel use was associated with a higher prevalence and higher number of CMBs. Whether this association is causal requires confirmation in prospective studies, especially given the small number of participants taking clopidogrel and the possibility of residual confounding in this study.

Tricuspid Annular Plane Systolic Excursion in the Assessment of Right Ventricular Function in Children and Adolescents after Repair of Tetralogy of Fallot
Conclusions: TAPSE is reproducibly measured by echocardiography in patients with TOF. It is not associated with RV ejection fraction or exercise performance, and its association with RV stroke volume may be confounded by body size. On the basis of these results, TAPSE is not representative of global RV performance in patients with TOF.
