BACKGROUND: We aimed to assess the relationship between echocardiographic characteristics and mortality in patients with chronic obstructive pulmonary disease (COPD). METHODS: We prospectively studied 154 patients (mean age 71 ± 10 years, 71% male) with COPD. All patients underwent transthoracic Doppler echocardiography within 48 hours of hospital admission. Primary endpoint was all-cause mortality during a median period of 22 months. RESULTS: Mildly elevated tricuspid regurgitation pressure and mitral E/e' ratio were the most commonly encountered echocardiographic abnormalities, observed in 60% and 56% of patients, respectively...

PURPOSE OF REVIEW: Assessment of diastolic function by echocardiography is challenging but important. Left ventricular filling has been more extensively studied than the right ventricle, and predominantly in adult populations. Although multiple parameters exist to assess diastolic function, they all have limitations, including load and heart rate dependency, which make assessment of diastolic function particularly challenging. The purpose of this article is to review evolving concepts and modalities for echo assessment of diastolic function in children...

Coarctation of the aorta (CoA) is the most common ductal-dependent lesion missed on neonatal exam screening. Prenatal diagnosis of CoA improves outcomes through early initiation of prostaglandin. Fetal echocardiographic parameters including 2D and Doppler findings have been studied as predictive measures for fetal diagnosis of CoA, but diagnosis rates remain variable. A comprehensive set of predictor variables was applied to fetuses suspected of CoA to analyze which parameters were associated with postnatal CoA...

Pulmonary regurgitation (PR) is a common residual lesion and major determinant of outcome following surgical repair for tetralogy of Fallot. We sought to longitudinally study a previously described echocardiographic index as a correlate of PR measured by cardiac magnetic resonance imaging (CMR). We conducted a retrospective longitudinal study of patients with baseline and follow-up echocardiogram and CMR. The baseline studies were obtained as part of a research protocol, while the follow-up studies were performed for clinical purposes...

In infants with a single right ventricle (RV), stage I palliation involves aortic reconstruction, systemic-to-pulmonary shunt placement, and atrial septectomy. Many require re-intervention for residual coarctation of the aorta (CoA). Doppler echocardiography can detect residual CoA in most infants, but its ability to predict severity has not been studied. This study compares gradients from Doppler interrogation to those from cardiac catheterization in infants with residual CoA. We performed a retrospective study of infants after stage I palliation from 2000 to 2014...

: Diastolic dysfunction is important in the pathophysiology of heart failure with preserved ejection fraction (HFpEF). Sympathetic nervous hyperactivity may contribute to the development of diastolic dysfunction. The aim of this study was to determine the relationship between myocardial sympathetic innervation quantified by (11)C-hydroxyephedrine positron emission tomography (PET) and diastolic dysfunction in HFpEF patients. METHODS: Forty-one HFpEF patients having an echocardiographic left ventricular ejection fraction ≥ 40% and 12 age-matched volunteers without heart failure underwent the echocardiographic examination and (11)C-hydroxyephedrine PET...

BACKGROUND: Coronary artery calcification (CAC) is common in patients with chronic kidney disease on hemodialysis (CKD-5D) and is an important predictor of mortality. However, cardiac functional links between CAC and mortality have not been well established. This study tested the hypothesis that CAC increases mortality by adversely affecting cardiac function. METHODS: Patients were recruited from 37 regional dialysis centers. 2-D and Doppler echocardiographic analyses were performed, and CAC was measured using 64-slice computed tomography...
