Stress echocardiography in coronary artery disease: a practical guideline from the British Society of Echocardiography.

Stress echocardiography is an established technique for assessing coronary artery disease. It has primarily been used for the diagnosis and assessment of patients presenting with chest pain in whom there is an intermediate probability of coronary artery disease. In addition, it is used for risk stratification and to guide revascularisation in patients with known ischaemic heart disease.

Prevalence of moderate-to-severe TR suitable for percutaneous intervention in TTE patients.

Moderate-to-severe tricuspid regurgitation is associated with higher mortality and morbidity yet remains significantly undertreated. The reasons for this are complex but include a higher operative mortality for patients undergoing isolated tricuspid valve surgery. This study sought to determine the prevalence of patients with moderate-to-severe tricuspid regurgitation and identify those who could be potentially suitable for percutaneous tricuspid valve intervention by screening patients referred for transthoracic echocardiography (ECHO) at a tertiary center.

Three-dimensional echocardiographic quantification of the left-heart chambers using an automated adaptive analytics algorithm: multicentre validation study.

Aims: Although recommended by current guidelines, adoption of three-dimensional echocardiographic (3DE) chamber quantification in clinical practice has lagged because of time-consuming analysis. We recently validated an automated algorithm that measures left atrial (LA) and left ventricular (LV) volumes and ejection fraction (EF). This study aimed to determine the accuracy and reproducibility of these measurements in a multicentre setting.

Incidence and predictors of early left ventricular thrombus after ST-elevation myocardial infarction in the contemporary era of primary percutaneous coronary intervention.

The aim of this study was to define the incidence of left ventricular thrombus (LVT) and its predictors in the contemporary era of primary percutaneous intervention (pPCI) and contrast echocardiography. We retrospectively analyzed 1,059 patients presenting with ST-elevation myocardial infarction (STEMI) to our tertiary cardiac center and treated with pPCI. Preprocedural pharmacology and procedural technique (including access route, the use of drug-eluting stents, and thrombectomy) were at the operators' discretion.

Pocket-size imaging device: effectiveness for ward-based transthoracic studies.

Aims: Pocket-size imaging devices (PSID) are now available; their potential role in a hospital environment has been investigated but still remains undefined.

Methods And Results: We evaluated the effectiveness of PSID in 92 patients referred for bedside transthoracic echocardiogram (TTE). Patients were included where there was a focused clinical question: quantification of left ventricular function (LVF); presence of regional wall motion abnormalities (RWMA); evidence of pericardial effusion, exclusion of significant valve pathology.

The additive value of three-dimensional derived left atrial volume and carotid imaging in dobutamine stress echocardiography.

Aims: to evaluate whether the three-dimensional (3D) left atrial volume index (LAVI) and/or the presence of carotid plaques (CP) can predict the result of dobutamine stress echocardiography (DSE), thereby aiding interpretation.

Methods And Results: we studied 130 patients (52 male, mean age 63 ± 11 years) with normal resting wall motion (WM) undergoing DSE. All patients had the end-systolic 2D and 3D LAVI measured, as well as bilateral carotid scanning.

The potential impact of contemporary transthoracic echocardiography on the management of patients with native valve endocarditis: a comparison with transesophageal echocardiography.

Background: Between 1987 and 1994, several studies demostrated transthoracic echocardiography (TTE) to be less sensitive than transesophageal echocardiography (TEE) in detecting native valve endocarditis. Recent technologic advances, especially the introduction of harmonic imaging and digital processing and storage, have improved TTE image quality. The aim of this study was to determine the diagnostic accuracy of contemporary TTE.
