BACKGROUND: Fabry cardiomyopathy (FC) and light-chain amyloid cardiomyopathy (AL) present with concentric left ventricular (LV) hypertrophy/remodeling and diastolic rather than systolic dysfunction. Direct comparisons are difficult due to rarity and confounded by variability of LV thickness. AIMS: To compare LV diastolic and systolic properties between patients with FC and AL in a cohort matched for interventricular septal thickness (IVS). METHODS: A two-center echocardiographic analysis was performed, comprising 118 patients with IVS ≥12 mm (FC and AL 59 patients each) matched by IVS...

BACKGROUND AND AIM: Whether aging affects left ventricular (LV) filling and ejection and the LV electric function is not well established. We investigated the effect of normal aging on echocardiographic measurements of LV morphology and function, LV electric function and the relationship between LV electric and mechanical function in asymptomatic individuals. METHODS: As part of a cross-sectional survey for the prevalence of coronary risk factors in the general population in Caltanissetta, Italy, individuals without signs or symptoms of coronary artery disease or heart failure were randomly selected and underwent electrocardiographic and echocardiographic examination...

AIMS: The early diastolic mitral annular velocity (e') and mitral E/e' criteria for clinically evaluating diastolic dysfunction in patients with atrial fibrillation (AF) are almost the same as in patients with sinus rhythm. In this study, we aimed to investigate whether e' is useful to assess diastolic function in AF patients. METHODS: Thirty patients who underwent successful electric cardioversion (EC) due to persistent AF and who maintained sinus rhythm for 1 month after EC were enrolled in this study...

We report a 7-year-old boy with unilateral choanal atresia who was referred for cardiac consultation before surgery. On echocardiography, the heart was normal except the presence of a double-circle appearance and a V-shaped structure on the suprasternal notch view. Cardiac computed tomography (CT) angiography confirmed the diagnosis of the double left innominate vein (DLIV). DLIV is a rare systemic venous anomaly, which often produces diagnostic confusion on echocardiography. Correct diagnosis is essential before performing any invasive procedure through this vein...

BACKGROUND: Left atrium (LA) function can be assessed by volumetric measurements, conventional and tissue Doppler, and more recently, deformation imaging using two-dimensional speckle tracking echocardiography (2DSTE). 2DSTE allows for measurement of volume and deformation and can quantify the contribution of the reservoir, conduit, and contraction phase. A common cause for LA dysfunction in very preterm infants is volume overload with a patent ductus arteriosus (PDA). The aim of this study was to explore the feasibility and reliability of LA 2DSTE in preterm infants, and describe LA function with and without PDA volume load...

We present the case of a 54-year-old man who had an unusual finding in contrast echocardiography with agitated saline. Partition of the right atrium in two compartments, an opacified and a non-opacified one, was noted. Further assessment with a transesophageal echocardiogram revealed the presence of a membrane in the right atrium, with the final diagnosis being cor triatriatum dexter.

BACKGROUND: Acute myocardial infarction (MI) leads to ventricular remodeling in response to oxygen demand. Such changes include left ventricular (LV) dilatation and increased myocardial wall stress. Prior studies showed that wall stress is a vital parameter of cardiac remodeling. However, outcome data are lacking. We aim to investigate wall stress post-MI in relation to biomarkers of cardiac remodeling and cardiovascular outcomes. METHODS: Patients presenting with ST-elevation MI (STEMI) requiring primary percutaneous intervention (PCI) were enrolled prospectively...

BACKGROUND: Right ventricle (RV) involvement causes acute systolic and diastolic functional alterations in the RV in patients after inferior myocardial infarction (IMI), which may result in an increase in left ventricle (LV) end-diastolic and right atrial (RA) pressure. In our study, we sought to evaluate RA volumes and mechanical functions using real-time three-dimensional echocardiography (RT3DE) in IMI patients with or without RV involvement. METHODS: Ninety-six consecutive patients with IMI (mean age: 59...

BACKGROUND: Pulmonary hypertension (PH) is a common cause of right ventricular (RV) remodeling and functional tricuspid regurgitation (FTR), but incremental pulmonary artery systolic pressure (PASP) does not always correlate with anatomic and functional RV changes. This study aimed to evaluate a noninvasive measure of pulmonary vascular resistance (PVR) for predicting RV dilatation, RV dysfunction, and severity of FTR. METHODS: We prospectively analyzed consecutive stable patients with PASP ≥ 35 mm Hg or any degree of RV dilatation or dysfunction secondary to PH...

Partial anomalous pulmonary venous return (PAPVR) comprises a group of congenital cardiovascular anomalies associated with pulmonary venous flow directly or indirectly into the right atrium. Scimitar syndrome is a variant of PAPVR in which the right lung is drained by right pulmonary veins connected anomalously to the inferior vena cava. Surgery is the definitive treatment for scimitar syndrome. However, it is not always necessary as many patients are asymptomatic, have small left-to-right shunts, and enjoy a normal life expectancy without surgery...

Absent pulmonary valve syndrome is a congenital heart defect usually associated with tetralogy of Fallot. Rarely, absent pulmonary valve syndrome can occur independently of tetralogy of Fallot and presents with an intact ventricular septum and a patent ductus arteriosus. This case report describes the prenatal diagnosis of absent pulmonary valve syndrome with intact ventricular septum via echocardiogram and the postnatal management of the resulting physiologic effects secondary to this rare congenital heart disease...

Coronary embolism (CE) is the underlying cause of 3% of acute coronary syndromes but is frequently overlooked in the differential diagnoses of acute coronary syndromes. The CE may be direct (left sided from the native or prosthetic heart valve, the left atrium, left atrial appendage or pulmonary venous bed), paradoxical (from the venous circulation through a patent foramen ovale, atrial septal defect, ventricular septal defects, cyanotic congenital heart defects or pulmonary arteriovenous malformations), or iatrogenic (following cardiac interventions...

BACKGROUND: Right ventricular (RV) systolic dysfunction has been associated with adverse outcomes in tetralogy of Fallot (TOF). However, the role and etiology of diastolic dysfunction remain incompletely defined. We assessed the association between traditional echocardiographic measures of diastolic function with catheter-based RV end-diastolic pressure (RVEDP) and identified clinical characteristics independently associated with diastolic dysfunction. METHODS: Single-center, retrospective cohort study of surgically repaired TOF patients undergoing cardiac catheterization with echocardiograms within 3 months prior to the catheterization...

The heart is a destination for metastases of various types of primary tumors, with lung, breast, melanoma, and mesothelioma being the most common types. Recurrent isolated cardiac metastasis presenting as a cavitary mass is rare. We present a case of recurrent isolated cavitary metastatic mass to the right atrium in a patient with the history of breast cancer who presented with new-onset atrial fibrillation. The patient successfully received radiation therapy with the resolution of the mass confirmed on repeat echocardiography...

Kawasaki disease (KD) is a vasculitis that affects medium-sized arteries and can lead to coronary artery aneurysms. KD should be considered in any infant presenting with prolonged fever. Delaying treatment beyond Day 10 of fever portends a high risk of coronary artery aneurysms. Echocardiography is often necessary to diagnose KD in young infants who frequently present without classic physical examination findings. We report on a case of KD with giant aneurysms in a 2-month-old infant. A combination of transthoracic echocardiography and CT angiography was utilized in the diagnosis as well as in the management of this infant...
