PURPOSE: The purpose of this study was to evaluate left ventricular (LV) deformation and LV dyssynchrony in patients with Wolff-Parkinson-White (WPW) syndrome and to identify the factors that affect the efficacy of radiofrequency catheter ablation (RFCA). METHODS: Thirty patients (26 men, mean age 40 ± 12 years) with WPW syndrome were prospectively recruited for this study. They underwent 2-dimensional transthoracic echocardiography with speckle tracking analysis before RFCA and again within 48 hours after RFCA...

PURPOSE: Heart failure (HF) is a multifactorial entity that combines derangements in both systolic and diastolic function. The relationship between systolic and diastolic function and exercise capacity is not fully understood. We sought to determine the mechanisms linking cardiac function and exercise tolerance in patients with HF. METHODS: One hundred fifty-six subjects with different cardiac function levels were included in the study. Subjects' 2D echocardiographic, 3D speckle tracking echocardiographic, and cardiopulmonary exercise testing (CPET) data were collected...

BACKGROUND: Right ventricular systolic pressure (RVSP) estimated by echocardiography is critical for the initial screening and follow-up of pulmonary hypertension (PH). Inter-observer variability (IOV) in RVSP can impact clinical decision making. This study assessed whether a simple guideline-based teaching intervention could reduce the IOV in RVSP interpretation. METHODS AND RESULTS: Eleven participants in a high-volume tertiary level echocardiography laboratory underwent an assessment of the baseline IOV in the assessment of RVSP for a series of transthoracic echocardiograms (TTE), depicting various degrees of PH among 8 cases each before and after a teaching intervention...

We herein describe the previously unreported combination of partial anomalous venous connection to the superior vena cava combined with situs inversus totalis. Following peripheral contrast injection, bubbles appeared initially in the left atrium allowing the diagnosis of a supra-atrial connection to be made using transthoracic echocardiography, but this timing was not anymore reproduced during transesophageal echocardiography performed minutes later. Cardiac computed tomography allowed the final diagnosis to be made...

BACKGROUND: The present study was designed to assess the underlying mechanism of decline in effort capacity seen with aging. METHODS: We analyzed 250 healthy senior patients (≥65 years) with an ejection fraction ≥60% who underwent a stress echocardiogram test. The seniors (aged 65-94) were divided into 3 equal age groups (groups 1, 2, and 3), and their echo characteristics at rest and peak exercise (measured and calculated) were compared. RESULTS: Diastolic function at rest declined significantly (E lateral, E septal, E/E', A) with age, while other rest parameters were similar...

BACKGROUND/OBJECTIVES: Controversy surrounds the prognosis and management of patients with paradoxical low-flow severe aortic stenosis (AS) with preserved left ventricular ejection fraction (LVEF). It was not certain if patients in a particular flow category remained in the same category as disease progressed. We investigated whether there were switches in categories and if so, their predictors. METHODS: Consecutive subjects (n = 203) with isolated severe AS and paired echocardiography (>180 days apart) were studied...

Percutaneous closure of an atrial septal defect in the cardiac catheterization laboratory requires noninvasive imaging to assist in characterization of the atrial septal defect and deployment of the device. Transesophageal echocardiography is the modality most often used in these circumstances. Transesophageal echocardiographic guidelines exist for the assessment and guidance for atrial septal defect closures, but these guidelines do not mention transgastric views. In this case, we demonstrate that transgastric views are helpful in describing the atrial septal defect, especially as it concerns the inferior vena cava rim...

In cases of pulmonary atresia with ventricular septal defect (PA-VSD), coronary-pulmonary arterial fistula (CPAF) as the main source of pulmonary blood supply is extremely rare. These fistulae may arise from the left coronary artery, right coronary artery, or a single coronary artery. Fistulae from a single coronary artery are unusual. We are reporting a case of PA-VSD with single coronary artery and CPAF as the main source of pulmonary supply in addition to two major aortopulmonary collateral arteries (MAPCAS)...

Artifacts are by-products of ultrasound imaging that may cause confusion or misdiagnosis if not interpreted correctly. There are, however, several disorders where a specific pattern of artifacts can aid in diagnosis, especially when the object in question cannot be visualized directly. In this manuscript, we report two patients with reverberation and shadow artifacts originating from the housing and the propeller of a continuous-flow intra-pericardial left ventricular assist device. Visualization of the artifacts required modified transthoracic views, so these artifacts should not pose a diagnostic challenge during a routine echocardiographic evaluation...

Left atrial appendage (LAA) closure prevents thromboembolic risk and avoids lifelong anticoagulation due to atrial fibrillation (AF). Nowadays, AtriClip, a modern epicardial device approved in June 2010, allows external and safe closure of LAA in patients undergoing cardiac surgery during other open-chest cardiac surgical procedures. Such a surgical approach and its epicardial deployment differentiates LAA closure with AtriClip from percutaneous closure techniques such as Watchman (Boston Scientific, Marlborough, MA, USA), Lariat (SentreHEART Inc...

BACKGROUND: Cardiac resynchronization therapy (CRT) may improve secondary mitral regurgitation (MR) in patients with cardiomyopathy. The effects on mitral valve (MV) and left ventricular (LV) geometry, however, have not been clearly defined. METHODS: Between 2009 and 2012, 229 CRT implants were performed at a single academic center. Seventy-one had ≥mild MR at baseline and serial echocardiography, without subsequent MV intervention. The pre-CRT and follow-up echocardiograms were retrospectively reviewed for (1) MV and LV geometry measurements; (2) MR grade; and (3) LV remodeling indices...

OBJECTIVE: Epirubicin (Epi) is a potent and effective drug for many malignant cancers with serious cardiotoxicity. Therefore, layer-specific two-dimensional speckle tracking echocardiography (2D-STE) was used to evaluate the longitudinal and circumferential systolic function of the left ventricular for the early detection of cardiotoxicity in this retrospective work. METHODS: Overall, 130 female patients with postoperative breast cancer who did not receive radiotherapy were classified into three groups: Group A (control group, n = 40) without any chemotherapy; Group B (n = 44) administered Epi at 180 ~ 240 mg/m(2) ; and Group C (n = 46) administered Epi at ≥360 mg/m(2) ...

Identification of a hiatal hernia by computed tomography (CT) scanning, and particularly with axial imaging from a coronary artery calcium score exam, is often subjective. There are several CT features that are diagnostic or at least suggestive of a hiatal hernia. As a hiatal hernia may be the etiology of a chest pain syndrome, it is important to be aware of CT findings suggestive of such.

Total anomalous pulmonary venous connection (TAPVC) is a rare form of cyanotic congenital heart disease (CHD) that occurs when the pulmonary veins drain into a site other than the morphologic left atrium. As with other forms of CHD, TAPVC has been shown to cluster in families and is known to have genetic association. We report on a case series of familial TAPVC in three consecutive siblings. A combination of fetal echocardiography, transthoracic echocardiography, as well as cross-sectional imaging was utilized in the diagnosis as well as management of each sibling...

Obstructive prosthetic valve thrombosis (PVT) is a rare but severe complication that usually occurs in the presence of suboptimal anticoagulation. Although fluoroscopy is commonly used to detect abnormal leaflet motion as a surrogate marker for PVT, its inability to directly visualize adjacent tissue and valve physiology leaves it susceptible to miss clinically important PVT. In this manuscript, we report the case of a 54-year-old woman with a mechanical mitral valve who was admitted to our institute with exertional dyspnea...

BACKGROUND: A high proportion of stable hypertrophic cardiomyopathy (HCM) patients have elevated serum cardiac troponin I (cTnI), but its clinical and echocardiographic determinants are unknown. Our objective was to determine the prevalence and clinical predictors of positive troponin (cTnI+) in a well-defined population of HCM patients using a highly sensitive assay. METHODS: We retrospectively interrogated medical records of 167 stable HCM patients from 1/2011 to 3/2014...

BACKGROUND: Right ventricular (RV) function has great impact on the survival of heart transplantation recipients; therefore, careful evaluation is of high clinical importance. However, there is no standard conventional echocardiographic parameter to assess RV systolic function. Herein, we evaluated the correlation between echocardiographic parameters of RV systolic function and ejection fraction assessed by cardiac magnetic resonance imaging (MRI RVEF) in heart transplantation recipients...
