Rapid online quantification of left ventricular volume from real-time three-dimensional echocardiographic data

Abstract

Semi-automated detection of the LV endocardial surface from RT3DE data is suitable for clinical use because it allows rapid, accurate, and reproducible measurements of LV volumes, superior to conventional 2DE methods.

Can We Improve Outcomes in Patients With Previous Coronary Artery Bypass Surgery Admitted for Acute Coronary Syndrome?

“…This rate was higher than the one published by the TIMI group, 10 in which only 60% of patients were receiving aspirin and only 20% of patients were on ACE inhibitors, but comparable to a subanalysis of the GRACE registry. 23 This finding reinforces the importance of the long-term protective effect achieved with these 4 drug classes.…”

“…A higher number of patients and a longer follow-up could probably have enhanced the difference and, therefore, allowed us to conclude (as other authors have 10,17,[20][21][22] ) that patients with a history of CABG PCI and MI. This could be explained by adherence to guidelines in our series regarding surgical revascularization, and by the fact that this patient subgroup has a longer history of atherosclerotic disease.…”

“…The Thrombolysis in Myocardial Infarction (TIMI) III ACS subset registry found a similar result during the hospital stay and at 6 months; however, by 1 year the subgroup of patients with a history of CABG had a poorer prognosis (incidence of combined events, 39.3% vs 30.2%; P=.002). 10 Despite the poorer outcome, previous CABG was not an independent predictor of death in TIMI, 11 Global Registry of ABBREVIATIONS ACS: acute coronary syndrome BMS: bare-metal stent CABG: coronary artery bypass graft DES: drug-eluting stent MI: myocardial infarction NSTEMI: non-ST-elevation myocardial infarction STEMI: ST-elevation myocardial infarction UA: unstable angina All statistical tests were 2-tailed, and a P less than .05 was considered significant. All analyses were performed using SPSS 15 (Statistical Package for Social Sciences, SPSS Inc, Chicago, Illinois, United States).…”

Expert Consensus for Multimodality Imaging Evaluation of Adult Patients during and after Cancer Therapy: A Report from the American Society of Echocardiography and the European Association of Cardiovascular Imaging

“…These factors include LV geometric assumptions, inadequate visualization of the true LV apex, lack of consideration of subtle regional wall motion abnormalities, and inherent variability of the measurement. 42 It is also important to bear in mind the load dependency of this measurement. Changes in loading conditions are frequent during chemotherapy and may affect the LVEF value (volume expansion due to the intravenous administration of chemotherapy or volume contraction due to vomiting or diarrhoea).…”

The expanding role of left ventricular functional assessment using gated myocardial perfusion SPECT: the supporting actor is stealing the scene

“…This last limitation is especially evident in patients with abnormal ventricles, also because geometric assumptions are needed with the standard two-dimensional technique [131,[133][134][135][136]. It can be overcome by the use of three-dimensional echocardiography, but this technique still suffers from the problems of acoustic window and imaging artefacts [133,137].…”
