Filter by:Sepsis induces a reversible systolic and diastolic cardiac dysfunction. The presence of a left ventricular (LV) diastolic dysfunction during septic shock could favor harmful volume overload. Recently, a meta-analysis suggested a negative prognostic role of LV diastolic dysfunction in septic patients (Od Ratio: 1.82; 95%CI: 1.12 - 2.97; p = 0.02) but its external validity is hampered by the numerous limits and the heterogeneity of the studies. To date, a pathophysiological link between LV diastolic dysfunction associated with septic shock and the water balance (reflecting volume overload) remains to establish. In addition, small size studies reported an excess of mortality in patients with septic shock who were diagnosed with a high cardiac output. However, no large cohort has yet confirmed the negative prognostic role of a hyperkinetic hemodynamic profile at the initial phase of septic shock.
This retrospective, cross-sectional cohort study was conducted to investigate the novice practitioners' learning curve of visual estimation of LV ejection fraction (%) through a echocardiographic video files at the academic emergency department (ED) in tertiary urban hospital.
The aims of the study is to investigate the right ventricular responses to mild hypercarbia after mitral valve prolapse repair surgery by the measurements obtained on pulmonary arterial catheter and transesophageal echocardiography.
This study will compare findings using a handheld ultrasound device (GE VScan) with those using a diagnostic ultrasound machine in adult patients referred for transthoracic echo (TTE), prior to non-cardiac surgery at Hammersmith Hospital, London. The handheld TTE (VTTE) will follow the standard Hammersmith Hospital diagnostic TTE (DTTE) protocol (with the exception of spectral Doppler) and will be reported on a simple 'tick box' form. A different echocardiographer will then perform and report the DTTE as per routine practice. The results from VTTE and DTTE will be directly compared. The echocardiographers performing the VTTE and DTTE are all fully accredited in diagnostic TTE and will be blinded to each others findings. The study aims to recruit a total of 96 patients with an anticipated study completion date of November 2015.
The objective of this study is analyze the influence of TV entertainment in children less than 3 years of age during echocardiography in order to achieve a complete and accurate test. This is an experimental study in children with suspected congenital or acquired cardiac disease. An examination room was prepared with a TV on the ceiling that was positioned in a way that would provide unobstructed viewing for children during the echocardiography procedure.
Inactivity among schoolchildren is a challenge to public health and for the municipality in particular. This study´s aim is to evaluate the cognitive and physical as well as social and fitness adaptations, and learning outcomes of short- and long term ball training for 9-11 years old girls and boys, and to determine to what extend the organisation (5x12 minutes og 3x40 minute a week) and type of training (ball games, circuit training or running) influence the magnitude of response.
This study examines the impact of adding a statement to the echocardiography report that advises anyone reading the report regarding if and when a follow-up study is recommended.
Empirical implantation of the left ventricular lead is the prevailing practice in cardiac resynchronization therapy device implantation. The response rate to the therapy has been uniformly 70% only despite various methods to screen patients before device implantation. This study tested the hypothesis that echocardiography to assess acute resynchronization of the left ventricle during device implantation may improve the response rate to the therapy.
This prospective surveillance trial will gather safety information for Optison when it is used in routine practice.
The purpose of this study is to evaluate the effects of ranolazine, an FDA-approved medication for the treatment of angina, on heart function by using echocardiography.
