OBJECTIVE: To determine to what extent inaccuracies in measuring the end diastolic diameter of the left ventricle, the interventricular septum, and the posterior wall, by M mode echocardiography influence the left ventricular mass calculated by the Devereuxs formula. DESIGN: Mathematical model. RESULTS: Relatively small measurement inaccuracies such as 5%, which are known to be inherent in the echocardiographic method, will result in "changes" of left ventricular mass in the range of 8% to 15%. This is equivalent to expected changes in left ventricular mass seen during treatment. CONCLUSIONS: The use of Devereuxs formula to calculate left ventricular mass is limited by measurement inaccuracies in individual patients.. ...

TY - JOUR. T1 - Noninvasive visualization of the left main coronary artery by cross sectional echocardiography. AU - Weyman, A. E.. AU - Feigenbaum, Harvey. AU - Dillon, J. C.. AU - Johnston, K. W.. AU - Eggleton, R. C.. PY - 1976. Y1 - 1976. N2 - Real time cross sectional echocardiographic studies of the left main coronary artery (LMCA) were performed in 15 normal patients, 15 patients with angiographically proven coronary artery disease but normal left main coronary segments, three patients with greater than 75% obstruction of the left main coronary artery, and one patient with a large aneurysm of the left main coronary artery. In normal subjects the LMCA evaginates from the inferolateral wall of the aorta. The artery appears as two dominant parallel linear echoes separated by a clear space representing the lumen of the vessel. The LMCA courses beneath the right ventricular outflow tract and can generally be followed to its expected point of bifurcation. Confirmation that this structure was in ...
This investigation was designed to determine the role of echocardiography in the assessment of left ventricular function in patients with significant coronary arterial disease. Satisfactory echocardiograms were obtained in 43 patients with coronary arterial disease. The ventriculographic ejection fraction was determined by the area length method. The echocardiographic left ventricular end-diastolic dimension was increased to more than 5-4 cm in 17 patients. Fifteen of these patients had an ejection fraction of 0-45 or less. Three patients had a normal left ventricular end-diastolic dimension but an ejection fraction of less than 0-45. Twenty-three patients had an ejection fraction of more than 0-45 and a normal left ventricular end-diastolic dimension. The left ventricular end-diastolic dimension index was increased (greater than 3 cm/m2) in 15 patients, all of whom had ejection fraction of less than 0-45. Three patients had a normal left ventricular end-diastolic dimension index and an ejection ...
To test the feasibility of imaging the left main coronary artery (LMCA) noninvasively as a means of detecting left main coronary artery disease, we studied 73 patients who underwent cardiac catheterization and cross-sectional echocardiography. Fifty-two had a normal LMCA (controls) and 21 had significant obstruction (greater than or equal to 50% luminal reduction). The apical, tomographic, cross-sectional, phased-array, echocardiographic approach was used, and the LMCA was imaged in 52 of 73 patients (71%). In 34 of 36 controls (94%) the LMCA was correctly judged as having no luminal obstruction. In the other two, and asymmetric, high-intensity echo in one wall of the artery suggested atherosclerotic disease, but coronary angiography revealed no obstruction. In 12 of 16 patients (75%) in whom significant LMCA disease was imaged, obstruction was predicted by echocardiographic criteria of either luminal irregularity or an asymmetric, high-intensity echo in the arterial wall. This preliminary study ...
OBJECTIVE: To investigate the changes of left ventricular structure and function in patients with liver cirrhosis and their correlation with the model for end-stage liver disease (MELD) score. METHODS: A total of 89 cirrhotic patients admitted between June, 2012 and June, 2014 and 30 healthy control subjects were enrolled in the study. According to MELD score, the cirrhotic patients were divided into 3 groups with MELD scores ≤9, between 10 and 19, and ≥20. The parameters of the left ventricle in resting state were measured using Doppler echocardiography, including left ventricular end systolic diameter (LVESD), left ventricular end diastolic diameter (LVEDD), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), left atrial diameter (LAD), ejection fraction (LVEF), cardiac output (CO), mitral flow velocity, and E wave deceleration time (DT), and evaluated their relationship with MELD score ...
A method for generating a synthesis echocardiographic image comprises first obtaining, for a plurality of pathologically similar reference hearts, a reference echocardiographic image of each reference heart at end-systole and at end-diastole. Next, the coupled epicardial and endocardial borders are identified in each echocardiographic image. An epicardial/endocardial border pair is then modeled from the identified borders. The method then locates a plurality of predetermined features in the reference echocardiographic images. The predetermined features are then located in the subject echocardiographic image from the location of the predetermined features in the reference echocardiographic images. The modeled epicardial/endocardial border pair is then mapped onto the subject echocardiographic image relative to the location of the predetermined features in the subject echocardiographic image. The apparatus generally comprises an echocardiographic machine for obtaining the echocardiographic images that are

N2 - We have presented recommendations for the optimum acquisition of quantitative two-dimensional data in the current echocardiographic environment. It is likely that advances in imaging may enhance or supplement these approaches. For example, three-dimensional reconstruction methods may greatly augment the accuracy of volume determination if they become more efficient. The development of three-dimensional methods will depend in turn on vastly improved transthoracic resolution similar to that now obtainable by transesophageal echocardiography. ...

Quantification of myocardial blood flow reserve in patients with CAD using real-time myocardial contrast echocardiography (RTMCE) has been demonstrated to further improve accuracy over the analysis of wall motion and qualitative analysis of myocardial perfusion.. Conventional stress echocardiography compares wall motion during rest and stress. The FDA has approved a contrast agent for use in patients with suboptimal echocardiograms, which accounts for up to 20% of resting echo studies. A "suboptimal image" is one in which at least two of six myocardial segments of the left ventricle cannot be visualized in the apical views. Contrast is used to opacify the LV chamber and to improve the delineation of the left ventricular endocardial border. Patient with suboptimal echoes include technically difficult patients, such as obese patients; patients undergoing mechanical ventilation; or patients with pulmonary hypertension.. Thomas R. Porter, MD, Chair of Cardiology at the University of Nebraska Medical ...
Currently, there is a paucity of investigations that have assessed the effects of RT on LV morphology and systolic function in healthy older individuals. We recently assessed the effects of 16 weeks of upper and lower extremity RT, in previously sedentary healthy older males (mean age: 68 years), on LV morphology, end-systolic meridional wall stress and LV systolic function (26). Resting two-dimensional echocardiograms were performed after 4, 8, 12 and 16 weeks of moderate (60% one repetition maximum, 1RM) to high (80% 1RM) intensity upper and lower extremity RT. The major finding of this investigation was that 16 weeks of RT was a sufficient stimulus to increase upper (+16%) and lower (+29%) extremity maximal muscular strength but was insufficient of a stimulus to alter LV posterior wall thickness, ventricular septal wall thickness, systolic or diastolic cavity dimensions, relative wall thickness and estimated LV mass (26). In addition, this form of training was not associated with an ...
Fifty consecutive patients undergoing aortic valve replacement for isolated aortic regurgitation were studied prospectively by echocardiography, electrocardiography and cardiac catheterization. Good quality echocardiograms were obtained in 49 of the 50 patients. Left ventricular (LV) dilatation was present in all 49 patients. LV systolic function, as assessed by echocardiographic percent fractional shortening, was normal in many patients but was moderately to severely reduced (less than 25%) in 14 patients (29%). Echocardiographic studies 6 months postoperatively revealed significant reductions in LV end-diastolic dimension (73.8 mm vs 58.7 mm; p less than 0.01), and serial echocardiographic studies early and late after operation revealed that the decrease in LV size had occurred by the time of the early study (8-22 days postoperatively), with little additional change thereafter. Operative deaths occurred in three of the 49 patients (6%). Eight of the 49 patients (16%) died of congestive heart ...
Background: There is conflicting information on the effects of oestrogen on the heart in women, especially those using postmenopausal hormone therapy. Whilst some studies reported a beneficial effect, others showed adverse outcomes. The interplay of lifestyle factors and type/timing of therapy remains to be clarified.. Aim: The aim of this study was to determine the effects of lifestyle and hormone therapy on heart function and structure in postmenopausal women.. Method: As part of a large longitudinal study of women randomly recruited from an urban population, the study assessed 410 suitable women by echocardiography in Year 1 and Year 5 of the study by two independent cardiologists.. Results: In lifestyle characteristics, the difference in age and body mass (as markers of cardiovascular risk) was in favour of never-users versus hormone therapy-users. Using an arbitrary cut-off ≥15% change for an effect, we found lifestyle factors had minimal effect on the two measured parameters - ejection ...
Echocardiography with its multiple modalities plays a central role in the evaluation of patients with known or suspected coronary artery disease, starting from the differential diagnosis of the patient presenting with acute chest pain. In the patient presenting with acute myocardial infarction (raised troponins) whether it is with ST-segment elevation or without, echocardiography is the first imaging modality used in order to ascertain the presence and extent of LV dysfunction and the presence of complications. In the absence of myocardial infarction (negative troponins), echocardiography will play an important diagnostic role in identifying the presence of reversible myocardial ischaemia. Stress echocardiography in many institutions is now the preferred stress modality associated with imaging as it is cost-effective and does not use ionizing radiation. Finally, echocardiography plays a pivotal role in the assessment of myocardial viability since the presence and extent of viable myocardium may ...
Non-invasiveness and instantaneous diagnostic capability are prominent features of the use of echocardiography in critical care. Sepsis and septic shock represent complex situations where early hemodynamic assessment and support are among the keys to therapeutic success. In this review, we discuss the range of applications of echocardiography in the management of the septic patient, and propose an echocardiography-based goal-oriented hemodynamic approach to septic shock. Echocardiography can play a key role in the critical septic patient management, by excluding cardiac causes for sepsis, and mostly by guiding hemodynamic management of those patients in whom sepsis reaches such a severity to jeopardize cardiovascular function. In recent years, there have been both increasing evidence and diffusion of the use of echocardiography as monitoring tool in the patients with hemodynamic compromise. Also thanks to echocardiography, the features of the well-known sepsis-related myocardial dysfunction have been
© 2014, Wiley Periodicals, Inc. Background Three-dimensional fusion echocardiography (3DFE) is a novel postprocessing approach that utilizes imaging data acquired from multiple 3D acquisitions. We assessed image quality, endocardial border definition, and cardiac wall motion in patients using 3DFE compared to standard 3D images (3D) and results obtained with contrast echocardiography (2DC). Methods Twenty-four patients (mean age 66.9 ± 13 years, 17 males, 7 females) undergoing 2DC had three, noncontrast, 3D apical volumes acquired at rest. Images were fused using an automated image fusion approach. Quality of the 3DFE was compared to both 3D and 2DC based on contrast-to-noise ratio (CNR) and endocardial border definition. We then compared clinical wall-motion score index (WMSI) calculated from 3DFE and 3D to those obtained from 2DC images. Results Fused 3D volumes had significantly improved CNR (8.92 ± 1.35 vs. 6.59 ± 1.19, P | 0.0005) and segmental image quality (2.42 ± 0.99 vs. 1.93 ± 1.18, P

Introduction: Large number of patients with heart failure (HF) have left bundle branch block (LBBB). Most precise method for identification of intraventricular dyssynchrony is tissue Doppler imaging (TDI). Purpose of this research was to compare left ventricular (LV) mechanical dyssynchrony in LBBB patients with and without HF and to compare various methods of LV systolic dyssynchrony assessment by TDI. Materials and Methods: One hundred and sixteen patients with a diagnosis of LBBB were included in the study. All patients underwent conventional two-dimensional echocardiography for global LV function assessment. LV systolic dyssynchrony was measured by opposing wall delay, maximum delay, and Yu index. LBBB patients were grouped into four classes according to their LV function and the presence or absence of HF, normal LV function without HF (Group A), normal LV function with HF (Group B), LV dysfunction with HF (Group C), and LV dysfunction without HF (Group D). Results: LV systolic dyssynchrony ...

The spectrum of anomalies in hearts having a univentricular atrioventricular (AV) connection was examined by two-dimensional echocardiography in 183 patients and the anatomic findings were compared with angiography. The mode of AV connection was found to be of three types: 1) double inletvia two A V valves; 2) singleinlet via one AV valve with absence of the other (left or right AV valve atresia); and 3) common inletvia a common AV valve. Identification of an accessory chamber by two-dimensional echocardiography was possible with 90% sensitivity, but it was limited compared with angiography in patients with severely hypoplastic anterior Chambers and pulmonary valve atresia. All patients with subaortic outlet foramen obstruction were detected. Great artery position and the presence of obstruction to pulmonary flow were correctly predicted in all but one patient. Two-dimensional echocardiography was superior to angiography for the detection of AV valve abnormalities which were present in 27% and ...

INTRODUCTION. Exercise echocardiography (EE) has advanced significantly from the diagnostic point of view, and several recent studies (most carried out at the same center) have shown that the extent of resting or exercise- induced ventricular dysfunction is a robust predictor of cardiac death and myocardial infarction.1-10. The purpose of this study was to investigate whether the number and location of diseased territories during the exercise peak, as well as the type of response to exercise (ischemia, necrosis or remote ischemia) influenced risk stratification more than clinical, stress test, and resting echocardiography variables in patients with known or suspected coronary artery disease (CAD). We also investigated whether EE supplemented resting echocardiography in patients with a history of acute myocardial infarction (AMI) as recorded in the medical history.. PATIENTS AND METHODS. Patients. We studied 2479 patients who had undergone treadmill EE at our institution during a 4.2-year period ...

Enlargement and hypertrophy are basic processes of LV remodeling, whether the initial disease is volume overload or dysfunction of the LV [1, 2, 4, 34, 40]. However, this compensatory response that allows cardiac output to be maintained is not innocuous and may lead to increased wall stress [41]and progression of LV dysfunction [2, 3, 8], which can be reversed by promptly decreasing the size of the LV [7, 30]. Therefore, monitoring LV size is a major goal of cardiac imaging. Many formulas have been developed to estimate volume based on dimensions measured by M-mode echocardiography, but have been limited by their geometric assumptions [42, 43]. Although limited pilot data indicate an excellent correlation between LV diameter obtained by M-mode echocardiography and angiographic volume measurements [44], this correlation was not optimal for enlarged LVs [45]. In the present study, the correlation between simultaneously measured LV diameters and volumes was good overall, suggesting that diameter ...

Doppler echocardiography is a fundamental instrument to understand heart damage during essential arterial hypertension. Left ventricular (LV) hypertrophy may also be conveniently studied in its morphological and functional aspects by ultrasound application. Echocardiography can also provide important morphological and functional information in hypertensive patients for therapeutic management and prognostic stratification. In recent years, echocardiography has been enriched by very refined techniques that are capable of studying the physiopathological intramyocardial phenomena: (i) tissue Doppler (which studies intramyocardial velocities and time intervals and allows the analysis of strain and strain rate); (ii) integrated backscatter (which analyzes variations of myocardial reflectivity in decibels); (iii) transthoracic Doppler derived coronary flow reserve (which quantifies the vasodilator response of coronary velocities to a hyperaemic stimulation); (iv) myocardial echo-contrast- ...

These results find that calcium seen by echocardiography identifies patients at increased risk of death or myocardial infarction. However, the practical relevance of this remains unclear. What should we do with this information? Are there any treatment options that alter outcomes in these patients? We simply do not know. This may be similar to coronary computed tomography calcification, which has been associated with increased risk of adverse events in many large studies. Nevertheless, we have failed to demonstrate convincing evidence that targeted therapy of patients with elevated coronary calcification alters outcomes. Calcification noted on echocardiography may be in a similar situation; until we have data demonstrating that treatment changes outcomes, it is hard to know what to do with these findings. ...

The technology of both modalities is rapidly evolving, and although CMR is becoming more widely available, the availability of miniaturized systems has made echocardiography ubiquitous. As is always the case, both viewpoints in this iForum are correct. We should not lose sight of the fact that the main burden of HF is in the community. The primary goal of the initial test is, therefore, to categorize patients according to whether they have HF with impaired or preserved function; this information determines therapy and is probably the reason that imaging has been shown to have an effect on outcome (7) and hemodynamics. Echocardiography is unmatched in its ability to assess cardiac physiology in the clinical setting. It is the only widely available technique that allows accurate noninvasive estimation of left atrial and pulmonary arterial pressures. Both tests are able to evaluate complications of HF such as intracardiac thrombus, LV aneurysm, and valve dysfunction. Echocardiography remains the ...
We compared the diagnostic utility of MRI with that of CT and selected echocardiographic measures, for the first time, in a large unselected group of patients with CTD and suspected PAH. We have demonstrated that both MRI and echocardiographic indices have a good correlation with mPAP and PVR at the time of RHC and performed well in predicting the presence of PAH in a high-risk population. In addition, measures of volume and mass derived from MRI predicted outcome. In contrast, CT indices correlated only moderately with invasive measures of pulmonary hemodynamics and had poorer diagnostic utility for PAH.. Several studies have investigated the role of echocardiography in the assessment of PH and have shown strong correlation with mPAP and PVR at RHC, and our results are in agreement with previous reports23,24,25,26. Echocardiography is established in routine clinical practice for screening for PAH in SSc. The TG calculated from the peak tricuspid velocity is the most commonly used measure, with ...

INTRODUCTION The use of a contrast agent during echocardiography was first reported in 1968 by Gramiak and Shah at the University of Rochester [1]. The uses and applications of contrast echocardiography are still expanding, since numerous studies have shown its efficacy and safety. The committee on contrast echocardiography for the American Society of Echocardiography found only 32 cases of possible (always transient) toxicity out of 13,946 examinations surveyed [2]. Meltzer et al. [3] and Armstrong et al. Acting essentially as harmonic oscillators, gaseous bubbles pulsate strongly in the liquid medium at the resonant frequency, and greatly potentiate ultrasonic scattering and absorption cross sections, as compared to expectations based strictly on the actual bubble size. Small bubbles, on the order of 5 micron or less, resonate in the medical imaging band of 110 MHz, and such bubbles are also capable of unhindered microcirculatory passage. Unfortunately, as already reviewed, such bubbles ...
