Baseline and follow-up assessment of regional left ventricular volume using 3-dimensional echocardiography: comparison with cardiac magnetic resonanceEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The assessment of regional volumes is an option for analysis of the response of LV segments to interventions such as revascularization or cell therapy. We sought to compare regional volumes from 3D-echocardiography (3DE) with cardiac magnetic resonance (CMR) over follow-up.CMR regional volumes were assessed at baseline and after one year follow-up in 30 unselected patients (28men, 65+/-11years) presenting for evaluation of cardiac function with previous infarction. 3DE images were also gathered over 4 cardiac cycles and measurements were performed off-line. CMR images were obtained using a 1.5 Tesla scanner and measured of...

The accessory papillary muscle with inferior J-waves - peculiarity or hidden danger?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Originally described in 1953, today the so-called J-wave is the source of much controversy. As a marker of so-called "early repolarization", this variant has been regarded as a totally benign variant since the 1960's. However, since then a wealth of data have indicated that the J-wave may be a marker of a highly arrhythmogenic substrate with a resultant high risk of sudden cardiac death.In this case report a case of an accessory papillary muscle with a prominent J-wave is described. This may be the first of many possible cases where papillary muscle variants may be the cause of the J-wave. (Source: Cardiovascular Ultrasound)

Usefulness of NT-pro BNP monitoring to identify echocardiographic responders following cardiac resynchronization therapyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Background: Cardiac resynchronization therapy (CRT) improves left ventricular (LV) volumes, mitral regurgitation (MR) severity and symptoms of patients with heart failure (HF). However, [greater than or equal to] 30% of patients have no significant clinical or echocardiographic improvement following CRT. Reverse remodeling after CRT correlates with improved clinical outcomes. We hypothesized that in NT-pro BNP monitoring is accurate to identify responders following CRT.

This report refers to such a case where post-catheterization haematoma was suspected to cause an obstruction of the femoral vein. Spectral Doppler recordings of blood flow in the common femoral vein, up-stream, distal to the hemorrhagic area, confirmed the diagnosis of obstruction by demonstrating changes in the venous flow pattern in the common femoral vein, consistent with venous hypertension. Due to the poor quality of the ultrasound images, the exact cause of the obstruction had to be established by another imaging modality, not affected by haemorrhages. CT showed that the common femoral vein was compressed at the punc...

Sub-aortic tendon induced ST-segment elevation - a new echo-electrocardiographic phenomenon?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The causes for ST-segment elevation other than myocardial infarction are numerous. The existence of left ventricular false tendons has been known for more than a century. Currently, the clinical entities associated with these left ventricular false tendons include innocent murmurs and premature ventricular contractions. A case report is presented where such a false tendon, attached to the interventricular septum, is responsible for striking ST-segment elevation in the anterior precordial leads. It is proposed that this is a newly observed entity--that of subaortic tendon-induced ST-segment elevation. This is proposed as a ...

Methods: Fifty-one consecutive patients with heart failure (LV ejection fraction 27% +/- 5%, 67% ischemic cardiomyopathy) underwent exercise Doppler echocardiography before CRT implantation to assess global contractile reserve (improvement in LV ejection fraction) and local contractile reserve in the region of the LV pacing lead (assessed by radial strain using speckle tracking analysis). Responders were defined by an increase in stroke volume [gr...

Computer-assisted determination of left ventricular endocardial borders reduces variability in the echocardiographic assessment of ejection fractionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Background: Left ventricular size and function are important prognostic factors in heart disease. Their measurement is the most frequent reason for sending patients to the echo lab. These measurements have important implications for therapy but are sensitive to the skill of the operator. Earlier automated echo-based methods have not become widely used. The aim of our study was to evaluate an automatic echocardiographic method (with manual correction if needed) for determining left ventricular ejection fraction (LVEF) based on an active appearance model of the left ventricle (syngo(R)AutoEF, Siemens Medical Solutions). Comp...

The usefulness of contrast during exercise echocardiography for the assessment of systolic pulmonary pressureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: 1. The method is applicable in a large number of patients. 2. RV/RA gradients obtained at peak exercise are higher with the use of contrast, and the clinical meaning of this difference should be evaluated in a larger number of pts submitted to right heart cathetherism. The high number of false positives should lead to a higher diagnostic threshold. 3. This method seems to have relevant clinical value in the diagnosis of pulmonary arterial hypertension.

Effort angina in a patient with advanced coronary artery disease. role played by coronary angiography, IVUS and cardiac CT: case reportEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this report, we describe the case of a 62-year-old man whose effort angina was first evaluated with coronary angiography, but whose severe stenosis of the right coronary artery was only observed on cardiac CT and IVUS. This additional diagnosis promptly resulted in a therapeutic approach with percutaneous transluminal coronary angioplasty (PTCA). (Source: Cardiovascular Ultrasound)

Correlation between Progetto Cuore risk score and early cardiovascular damage in never treated subjectsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Our paper confirms previous studies about the association between a comprehensive risk score and signs of early cardiovascular damage. A temporally limited exposure to cardiovascular risk factors, in particular to blood pressure, is already able to induce significant changes in both the heart structure and the vascular wall. Also in a european low-risk population the use of a cardiovascular risk score program, such as the Progetto Cuore in Italy, allows a quite precise estimation of the possible cardiovascular damage.

Echocardiographic manifestation of hiatus hernia simulating a left atrial mass: Case reportEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Hiatus hernia can present as acute chest pain, while its echocardiographic manifestation may resemble a left atrial space-occupying structure. Physicians should be aware of the clinical and sonographic findings to facilitate the differential diagnosis from similarly presenting cardiac entities. (Source: Cardiovascular Ultrasound)

Endothelial function and urine albumin levels among asymptomatic Mexican- Americans and non-Hispanic whitesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Background: Mexican-Americans (MA) exhibit increases in various cardiovascular disease (CVD) risk factors compared to non-Hispanic Whites (NHW), yet are reported to have lower CVD mortality rates. Our aim was to help explain this apparent paradox by evaluating endothelial function and urine albumin levels in MA and NHW. Methods: One hundred-five MA and 100 NHW adults were studied by brachial artery flow-mediated dilatation (FMD), blood and urine tests. Participants were studied by ultrasound-determined brachial artery flow-mediated dilatation (FMD), blood and urine tests, at a single visit. Results: Despite higher BMI an...
