OBJECTIVES: The study sought to evaluate the potential clinical impact of using 3-dimensional echocardiography (3DE) to measure left ventricular ejection fraction (LVEF) in patients considered for implantable cardioverter-defibrillator (ICD) implantation and to assess the predictive value of 3DE LVEF for arrhythmic events. BACKGROUND: ICD therapy is currently recommended to prevent sudden cardiac death in patients with symptomatic heart failure and LVEF ≤35%, and in asymptomatic patients with ischemic heart disease and LVEF ≤30%...

OBJECTIVES: In this study, the authors hypothesized that intraprocedural improvement of pulmonary venous (PV) waveforms are predictive of improved outcomes. In this report, they analyzed intraprocedural invasive and echocardiographic changes with respect to rehospitalization and mortality. BACKGROUND: The effects of hemodynamic changes during percutaneous mitral valve repair (PMVR) with MitraClip (Abbott Vascular, Santa Clara, California) are incompletely characterized...

OBJECTIVES: This study was a comprehensive evaluation of cardiopulmonary function in patients with chronic thromboembolic (pulmonary vascular) disease (CTED) during exercise. BACKGROUND: Exertional dyspnea is frequent following pulmonary embolism, but only a minority of patients eventually develops chronic thromboembolic pulmonary hypertension (CTEPH). Better understanding of the factors that limit exercise capacity in patients with persistent pulmonary artery obstruction could help to further define the entity of CTED...

OBJECTIVES: This study sought to evaluate the effect of early intravenous metoprolol on left ventricular (LV) strain assessed with feature-tracking cardiovascular magnetic resonance (CMR). BACKGROUND: Early intravenous metoprolol before primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) portends better outcomes in the METOCARD-CNIC (Effect of Metoprolol in Cardioprotection During an Acute Myocardial Infarction) trial...

OBJECTIVES: This meta-analysis determined the diagnostic performance of coronary computed tomography (CT) angiography (CTA), CT myocardial perfusion (CTP), fractional flow reserve CT (FFRCT ), the transluminal attenuation gradient (TAG), and their combined use with CTA versus FFR as a reference standard for detection of hemodynamically significant coronary artery disease (CAD). BACKGROUND: CTA provides excellent anatomic, albeit limited functional information for the evaluation of CAD...

OBJECTIVES: This study sought to investigate the association between the extent, location, and pattern of late gadolinium enhancement (LGE) and outcome in a large dilated cardiomyopathy (DCM) cohort. BACKGROUND: The relationship between LGE and prognosis in DCM is incompletely understood. METHODS: We examined the association between LGE and all-cause mortality and a sudden cardiac death (SCD) composite based on the extent, location, and pattern of LGE in DCM...

OBJECTIVES: The association of left ventricular global longitudinal strain (LV-GLS) with clinical outcomes in patients with hypertrophic cardiomyopathy (HCM) has been examined in multiple studies. The authors conducted a systematic review aimed at summarizing and critically appraising the current evidence. BACKGROUND: HCM is a common genetic cardiovascular disease with an estimated prevalence of 1 in 500 patients. LV-GLS derived from speckle tracking echocardiography is a sensitive noninvasive method of assessing regional left ventricular function...

OBJECTIVES: In this study, the authors tested the hypotheses that the systolic stretch index (SSI) developed by computer modeling and applied using echocardiographic strain imaging may characterize the electromechanical substrate predictive of outcome following cardiac resynchronization therapy (CRT). They included patients with QRS width 120 to 149 ms or non-left bundle branch block (LBBB), where clinical uncertainty for CRT exists. They further tested the hypothesis that global longitudinal strain (GLS) has additional prognostic value...

OBJECTIVES: The aim of this study was to assess the utility of left ventricular (LV) entropy, a novel measure of myocardial heterogeneity, for predicting cardiovascular events in patients with dilated cardiomyopathy (DCM). BACKGROUND: Current risk stratification for ventricular arrhythmia in patients with DCM is imprecise. LV entropy is a measure of myocardial heterogeneity derived from cardiac magnetic resonance imaging that assesses the probability distribution of pixel signal intensities in the LV myocardium...
