OBJECTIVES: This meta-analysis investigated the diagnostic values of transthoracic echocardiography (TTE), 2-dimensional (2D) and 3-dimensional (3D) transesophageal echocardiography (TEE), and multidetector-row computed tomography (MDCT) in patients with suspected mechanical prosthetic valve obstruction (PVO) for detecting subprosthetic mass and differentiating its causes. BACKGROUND: Diagnostic values of advanced imaging modalities, such as MDCT and TEE, for the detection and differentiation of PVO have not been investigated...

OBJECTIVES: This study sought to compare the prognostic value of 2-dimensional (2D) right ventricular (RV) speckle tracking (STE) against cardiac magnetic resonance (CMR) RV ejection fraction (EF) and feature tracking (FT) and conventional echocardiographic parameters on overall and cardiovascular (CV) survival in patients with heart failure with reduced EF (HFrEF). BACKGROUND: Prior works showed that RV systolic function predicts prognosis in HFrEF. 2D RVSTE had recently been proposed as new echocardiographic method to evaluate RV dysfunction...

OBJECTIVES: The study sought to assess the performance of cardiovascular magnetic resonance (CMR) myocardial perfusion mapping against invasive coronary physiology reference standards for detecting coronary artery disease (CAD, defined by fractional flow reserve [FFR] ≤0.80), microvascular dysfunction (MVD) (defined by index of microcirculatory resistance [IMR] ≥25) and the ability to differentiate between the two. BACKGROUND: Differentiation of epicardial (CAD) and MVD in patients with stable angina remains challenging...

OBJECTIVES: This study sought to investigate how regional left ventricular (LV) function modifies septal motion in left bundle branch block (LBBB). BACKGROUND: In LBBB, the interventricular septum often has marked pre-ejection shortening, followed by immediate relengthening (rebound stretch). This motion, often referred to as septal flash, is associated with positive response to cardiac resynchronization therapy (CRT). METHODS: In 10 anesthetized dogs, we induced LBBB by radiofrequency ablation and occluded the circumflex (CX) (n = 10) and left anterior descending (LAD) (n = 6) coronary arteries, respectively...

OBJECTIVES: This study sought to assess speckle-tracking-derived parameters as predictors of first and subsequent ventricular events in patients with structural heart disease and implantable cardioverter-defibrillators (ICD). BACKGROUND: Left ventricular ejection fraction (LVEF), the current primary parameter of risk stratification for ventricular arrhythmias (VAs) in structural heart diseases is burdened by many limitations. METHODS: In this retrospective, observational study, all consecutive patients with structural heart disease were admitted for ICD implantation...

OBJECTIVES: This study sought to assess the presence and extent of focal and diffuse fibrosis in heart failure in patients with preserved ejection fraction (HFpEF) compared to asymptomatic control subjects, and the relationship of fibrosis to clinical outcome. BACKGROUND: Myocardial fibrosis has been implicated in the pathophysiology of HFpEF. METHODS: In this prospective, observational study, 140 subjects of similar age and sex (HFpEF: n = 96; control subjects: n = 44; 73 ± 8 years of age; 49% males) underwent cardiac magnetic resonance imaging...

OBJECTIVES: This study aimed to assess the association between increased lesion peri-coronary adipose tissue (PCAT) density and coronary 18 F-sodium fluoride (18 F-NaF) uptake on positron emission tomography (PET) in stable patients with high-risk coronary plaques (HRPs) shown on coronary computed tomography angiography (CTA). BACKGROUND: Coronary 18 F-NaF uptake reflects the rate of calcification of coronary atherosclerotic plaque. Increased PCAT density is associated with vascular inflammation...

OBJECTIVES: This study sought to assess the prognostic impact of cardiovascular magnetic resonance (CMR) and conventional risk factors in patients with myocardial infarction with nonobstructed coronaries (MINOCA). BACKGROUND: Myocardial infarction with nonobstructed coronary arteries (MINOCA) represents a diagnostic dilemma, and the prognostic markers have not been clarified. METHODS: A total of 388 consecutive patients with MINOCA undergoing cardiac magnetic resonance (CMR) assessment were identified retrospectively from a registry database and prospectively followed for a primary clinical endpoint of all-cause mortality...

OBJECTIVES: This study aimed to investigate clinical and coronary computed tomographic angiography (CTA) characteristics of lesions that progressed to chronic total occlusion (CTO). BACKGROUND: CTO is one of the most common reasons for referral to coronary artery bypass surgery. Prediction and adequate early management for future CTO lesions may be beneficial. METHODS: The study evaluated patients with at least 1 vessel with a diameter stenosis of ≥70% on invasive coronary angiography (ICA) who underwent previous coronary CTA >12 months before ICA, from 2006 to 2015...

OBJECTIVES: This study sought to evaluate whether velocity of naturally occurring myocardial shear waves (SW) could relate to myocardial stiffness (MS) in vivo. BACKGROUND: Cardiac SW imaging has been proposed as a noninvasive tool to assess MS. SWs occur after mechanical excitation of the myocardium (e.g., mitral valve closure [MVC] and aortic valve closure [AVC]), and their propagation velocity is theoretically related to MS, thus providing an opportunity to assess stiffness at end-diastole (ED) and end-systole...
