BACKGROUND: Adult studies demonstrate that echocardiographic measurements of cardiac function using speckle tracking correlate with invasive measurements, but such data in the pediatric population are sparse. Our aim was to compare speckle-derived measures of cardiac function to measurements routinely obtained by cardiac catheterization in children. METHODS: Echocardiograms were performed on the day of cardiac catheterization. Using Tomtec 2D Cardiac Performance Analysis, longitudinal strain (LS), longitudinal strain rate (LSR), early diastolic LSR, and ejection fraction (EF) for the right and left ventricle (RV and LV) were calculated via speckle tracking...

OBJECTIVES: The tricuspid annular plane systolic excursion (TAPSE) is a validated measure of right ventricular function; however, the apical echocardiographic window varies and has limitations in intensive care unit (ICU) patients receiving mechanical ventilation or those with underlying disease and air entrapment. We aimed to evaluate the subcostal echocardiographic assessment of tricuspid annular kick (SEATAK) as an alternative to TAPSE in critically ill patients. METHODS: To measure SEATAK, we obtained the subcostal inferior vena cava view and used M-mode to measure excursion of the tricuspid annulus (kick)...

BACKGROUND: Right atrium function and ventricular function have significant prognostic value in pulmonary arterial hypertension patients. Acute changes in right ventricular synchrony and right atrium function postiloprost inhalation have not been evaluated. METHODS: Cross-sectional study. Consecutive pulmonary arterial hypertension patients (group I from Nice classification) were included. Echocardiographic right atrium and right ventricular function pre- and postiloprost inhalation, including a right ventricular dyssynchrony index and right atrium function using speckle tracking, were performed in all patients...

Formation of an intramural left atrial hematoma (ILAH) is a rare complication of coronary artery stenting. Rapid diagnosis with noninvasive multimodality imaging can potentially be lifesaving. We report a case of ILAH that resulted in left ventricular inflow obstruction and pericardial tamponade in a 55-year-old male who presented with hemodynamic instability and worsening dyspnea three weeks after seemingly uncomplicated left circumflex artery stenting. We demonstrate features on transthoracic echocardiography with contrast and cardiac computed tomography that were used for diagnosis and management...

Aortic rupture and transection are constituents of the acute aortic syndrome. Injury to the thoracic aorta during motor vehicle crashes is associated with blunt chest trauma and rapid deceleration mechanisms. Type A dissections and/or rupture of the aorta at the level of the aortic isthmus are the more common presentations of aortic injuries associated with motor vehicle crashes. We present the case of atypical echocardiographic findings of a nearly complete circumferential transection of the proximal ascending aorta injury after a motorcycle crash...

INTRODUCTION: Quantification of mitral regurgitation (MR) by two-dimensional (2D) transthoracic echocardiography (TTE) is based on the analysis of the proximal flow convergence (PFC) and the "vena contracta" (VC). This method assumes geometries and can be misleading. In contrast, three-dimensional (3D) echocardiography directly measures flow volumes and does not assume geometries, which allows for more accurate MR evaluation. AIMS: To report the 3D transesophageal echocardiography (3DTEE) feasibility for MR quantification and evaluate its concordance with 2D echo...

Multi-imaging modalities should be considered in patients with atrial septal defects (ASDs) in which the degree of right ventricular enlargement is not fully explained by the small size of ASD found on conventional transthoracic echocardiography. We report a case of crescent-shaped superior sinus venosus ASD discriminated using real-time three-dimensional transesophageal echocardiography. MDCT confirmed its relationship with the superior vena cava and the absence of combined anomalies, such as the pulmonary venous return anomaly...

Congenital stenosis/atresia of a coronary artery is an exquisitely rare anomaly (Congenit Heart Dis, 2, 2007, 347) with increased risk of sudden death. Bilateral coronary obstruction is even more unusual but has been reported in conjunction with aortic valve disease, syphilis, and Takayasu's arteritis. To the best of our knowledge, obstruction of both coronaries in a pediatric patient has only been reported once (Ann Thorac Surg, 55, 1993, 1564). We present a patient with an intramural, anomalous aortic origin of the right coronary artery from the contralateral sinus (AAORCA) with near atresia of the left main coronary ostium...

BACKGROUND: Exercise-induced increase in pulmonary artery systolic pressure (PASP) as a possible measure of right ventricular (RV) contractile reserve has been shown to predict survival in severe pulmonary hypertension. However, RV contractile reserve can also be measured by changes in stroke volume (SV), tricuspid annular plane systolic excursion (TAPSE), or tricuspid annular systolic velocity (S'). The limits of normal values and the functional significance of these changes in healthy subjects are not well known...

We report a case of cyst was initially labeled as left ventricular noncompaction cardiomyopathy. An accurate diagnosis is essential to establish the most effective treatment strategy. In particular, echocardiographic examination assists in identifying the correct diagnosis. In this case, two-dimensional and three-dimensional echocardiography and computed tomography were used for definitive diagnosis of cardiac hydatid cyst.

A 71-year-old male presented after sudden onset of confusion and expressive aphasia. MRI head revealed multiple ischemic lesions consistent with cardio-embolic pathophysiology. A computed tomography angiography of lung showed peripheral pulmonary emboli. He underwent a transesophageal echocardiogram as a part of the stroke workup and was found to have vegetations on both aortic and tricuspid valves. The blood cultures did not show any growth, and the patient remained afebrile during the course of hospitalization...

BACKGROUND: Exercise stress echocardiography (ESEcho) is sufficiently sensitive and has high enough specificity for the clinical detection of coronary artery disease (CAD) in women. However, there was little data about the ability of ESEcho to detect CAD and predict clinical outcomes in female patients with chest pain and low global cardiovascular (CV) risks. The purposes of this study were (1) to determine the diagnostic accuracy of ESEcho, (2) to evaluate the clinical outcomes of major cardiovascular outcome (MACE), and (3) to assess the incremental prognostic value of ESEcho for the prediction of MACE in Korean female patients with low CV risks...

Very few cases of ventricular myxoma originate from a papillary muscle. Patients with a cardiac myxoma and a history of colorectal carcinoma are also rare. Here, we present a case of an extremely large right ventricular myxoma that originated from the posteromedial papillary muscle in a patient with a history of colorectal carcinoma.

A 61-year-old woman presented to the emergency room with atypical chest pain, non-diagnostic electrocardiogram, and an initial troponin level that was normal. A coronary computed tomography angio (CCTA) was performed, and on initial review, it appeared to be normal. Subsequent review including evaluation of functional data from the retrospective scan identified a distal left anterior descending occlusion and an apical wall-motion abnormality with no other evidence of heart disease. This case illustrates the complementary contribution of anatomic and functional data and serves to remind us that on rare occasions, what looks "normal" is not always normal...

BACKGROUND: Smoking is known to have many short- and long-term cardiovascular effects. Cardiac index (CI), which is cardiac output indexed to body surface area, is considered to be a valid measure of cardiac performance. We investigated whether there were any differences in CI or other echocardiographic variables between never smokers, ex-smokers, and current smokers in a cardiopulmonary healthy population. METHODS: Subjects (n=355) from a previous population-based respiratory questionnaire survey (never smokers, ex-smokers, and current smokers without significant chronic obstructive lung disease) were examined with echocardiography, and CI (L/min/m(2) ) was calculated...

Quantification of computed tomography (CT) noise helps in determination of radiation dosage requirements for adequate image quality. Clinical methods used include calculation of the standard deviation (SD) of a selected region of interest (ROI). In industry, wavelet decomposition has been used for image compression while removing high-frequency noise. We evaluated a cohort of 74 consecutive patients referred for coronary artery calcium scoring and quantitated noise within a 16×16 ROI in the ascending aorta using the traditional SD method and also using a two-dimensional dyadic wavelet decomposition method...

BACKGROUND: Coronary artery disease (CAD) is an important cause of morbidity and mortality in patients with diabetes. Silent myocardial ischemia (SMI) is common in patients with diabetes and is associated with poorer prognosis. Myocardial performance index "Tei index" that reflects both left ventricular (LV) systolic and diastolic function. The aim of our study was to test the value of Tei index in prediction of SMI in asymptomatic patients with type 2 diabetes. PATIENTS AND METHODS: Asymptomatic patients with type 2 diabetes were included in our study...

Myocardial clefts are defined as narrow, deep blood-filled invaginations within the left ventricular myocardium. They occur in hypertrophic cardiomyopathy patients with different frequency and represent a distinctive morphological expression of hypertrophic cardiomyopathy. Although two-dimensional transthoracic echocardiography is able to detect myocardial clefts in some cases, cardiovascular magnetic resonance imaging with its high spatial resolution can detect myocardial clefts not visualized with echocardiography...
