Reduced stroke distance of the left ventricular outflow tract is independently associated with long ‐term mortality, in patients hospitalized due to heart failure
ConclusionsStroke distance was associated with long‐term mortality, independently of other known echocardiographic prognostic factors in elderly patients hospitalized with heart failure. Only when stroke distance was excluded from analysis, LVEF became associated with mortality. Stroke distance had additive prognostic value.

Endovascular treatment of stroke in children under 2 years with heart failure and ventricular assist device.
CONCLUSION: As a result of the difficulty in performing arterial puncture, the small vessel calibre and the limitation in the use of iodated contrast, there are certain limitations to endovascular treatment of strokes in children that can lead to complications. A multidisciplinary approach to managing such cases would be helpful. PMID: 31072251 [PubMed - as supplied by publisher]

Transoesophageal echocardiography prior to catheter ablation could be avoided in atrial fibrillation patients with a low risk of stroke and without filling defects in the late-phase MDCT scan: A retrospective analysis of 783 patients
ConclusionsFor AF patients with low risk of stroke, when MDCT images showed no filling defect in the late phase, TEE prior to catheter ablation can be avoided.Key Points•MDCT can help detect the presence of LAA thrombus.•TEE can be avoided when late-phase MDCT shows no filling defect.•TEE is required in patients whose MDCT images indicate thrombus.

Pre-Load-Induced Changes in Forward LV Stroke and Functional Mitral Regurgitation: Echocardiographic Detection of the Descending Limb of Starling's Curve
Conclusions Heart failure patients with LV systolic dysfunction on the descending limb of the Starling curve can be recognized by the paradoxical decrease in LVSV despite PLL, and the prognostic predicting power is additive to the other traditional echocardiographic predictors. Also, our results suggest that functional mitral regurgitation is an important reason for the descending limb of the Starling curve, which is clinically recognized as the pre-load–induced decrease in forward LVSV.

Independent Prognostic Value of Stroke Volume Index in Patients With Immunoglobulin Light Chain Amyloidosis Cardio-Oncology
Conclusions: SV index prognostic performance was similar to left ventricular strain in predicting survival in AL amyloidosis, independently of biomarker staging. Because SV index is routinely calculated and widely available, it could serve as the preferred echocardiographic measure to predict outcomes in AL amyloidosis patients.

Stroke volume and cardiac output measurement in cardiac patients during a rehabilitation program: comparison between tonometry, impedancemetry and echocardiography
AbstractGiven the increasing use of noninvasive techniques for the assessment of cardiac function in clinical practice, the aim of this study was to evaluate if stroke volume (SV) and cardiac output (CO) measurements obtained by PhysioFlow impedance cardiography or HDI CR-2000 pulse wave analysis (Pulse) are interchangeable with measurements obtained by echocardiography in patients with coronary artery disease (CAD) or heart failure (HF). The study involved 48 men with heart disease (CAD or HF). We compared SV and CO measurements with the three devices at rest, as well as relative changes in SV and CO derived from a rehabi...

Contribution Of Mitral Valve Atrioventricular Plane Displacement To The Stroke Volume In Patients With Severe Mitral Regurgitation
Introduction: Longitudinal shortening measured as atrioventricular plane displacement (AVPD) represents a piston-like movement of the base of the ventricles toward the apex during the cardiac cycle. Prior studies using echocardiography and cardiac magnetic resonance imaging demonstrated AVPD to account for a large part of the left ventricular (LV) stroke volume (SV) in athletes, healthy controls, and heart failure patients. We sought to validate the use of cardiac computed tomography (CCT) to measure the AVPD and subsequently explore the contribution of the AVPD towards overall LV SV in patients with functional and primary...

High-Sensitivity Troponin T and Risk Stratification in Patients With Atrial Fibrillation During Treatment With Apixaban or Warfarin
ObjectivesThe aim of this study was to evaluate the prognostic value of high-sensitivity troponin T (hs-TnT) in addition to clinical risk factors and the CHA2DS2VASc (congestive heart failure, hypertension, 75 years of age and older, diabetes mellitus, previous stroke or transient ischemic attack, vascular disease, 65 to 74 years of age, female) risk score in patients with atrial fibrillation (AF).BackgroundThe level of troponin is a powerful predictor of cardiovascular events and mortality.MethodsA total of 14,897 patients with AF were randomized to treatment with apixaban or warfarin in the ARISTOTLE (Apixaban for the P...

Prospective Randomized Evaluation of the Watchman Left Atrial Appendage Closure Device in Patients With Atrial Fibrillation Versus Long-Term Warfarin Therapy The PREVAIL Trial
ConclusionsIn this trial, LAA occlusion was noninferior to warfarin for ischemic stroke prevention or SE>7 days’ post-procedure. Although noninferiority was not achieved for overall efficacy, event rates were low and numerically comparable in both arms. Procedural safety has significantly improved. This trial provides additional data that LAA occlusion is a reasonable alternative to warfarin therapy for stroke prevention in patients with NVAF who do not have an absolute contraindication to short-term warfarin therapy.

Whole-heart four-dimensional flow can be acquired with preserved quality without respiratory gating, facilitating clinical use: a head-to-head comparison
Background: Respiratory gating is often used in 4D-flow acquisition to reduce motion artifacts. However, gating increases scan time. The aim of this study was to investigate if respiratory gating can be excluded from 4D flow acquisitions without affecting quantitative intracardiac parameters. Methods: Eight volunteers underwent CMR at 1.5 T with a 5-channel coil (5ch). Imaging included 2D flow measurements and whole-heart 4D flow with and without respiratory gating (Resp(+), Resp(−)). Stroke volume (SV), particle-trace volumes, kinetic energy, and vortex-ring volume were obtained from 4D flow-data. These parameters were...

Prevalence and Prognostic Significance of Left Ventricular Noncompaction in Patients Referred for Cardiac Magnetic Resonance Imaging Magnetic Resonance Imaging
Conclusions— Current criteria for the diagnosis of LVNC leads to highly variable disease prevalence in patients referred for cardiac magnetic resonance. The diagnosis of LVNC, by any current criteria, was not associated with adverse clinical events on nearly 7 years of follow-up. Limited conclusions can be made for Captur criteria due to low observed prevalence.
