Atherosclerotic subclavian artery disease is detected in about 5% of patients referred for coronary artery bypass (CABG) surgery. The internal mammary artery, a branch of the subclavian artery, is the most frequently utilized graft to restore coronary circulation because of its longevity. Stenosis or occlusion of the subclavian artery can cause retrograde blood flow in the ipsilateral internal mammary artery, known as "steal," compromising coronary circulation supplied by the graft. Steal may be asymptomatic or may result in symptoms of myocardial ischemia...

BACKGROUND: Prenatal diagnosis of fetal total anomalous pulmonary vein connection (TAPVC) remains challenging for most screening sonographers. The purpose of this study was to evaluate the use of four-dimensional echocardiography with high-definition flow imaging and spatiotemporal image correlation (4D-HDFI) in identifying pulmonary veins in normal and TAPVC fetuses. MATERIAL & METHODS: We retrospectively reviewed and performed 4D-HDFI in 204 normal and 12 fetuses with confirmed diagnosis of TAPVC...

Papillary fibroelastoma is an uncommon primary cardiac tumor, predominantly associated with left-sided valvular endocardium. Affectation of tricuspid valve leaflets is rare, and management in asymptomatic patients remains controversial. We present a 30-year-old female referred for evaluation prior to bariatric surgery. A routine echocardiogram revealed a mobile cardiac mass attached to the tricuspid valve. A patent foramen ovale was also present. Tumor was surgically removed. Histology confirmed the definite diagnosis of a papillary fibroelastoma...

BACKGROUND: Frame rates (FR) used for strain analysis assessed by speckle tracking in fetal echocardiography show a considerable variation. The aim of this study was to investigate the influence of the FR on strain analysis in 2D speckle tracking. METHODS: Fetal echocardiography was performed prospectively on a Toshiba Aplio 500 system and a Toshiba Artida system, respectively. Based on an apical or basal four-chamber view of the fetal heart, cine loops were stored with a FR of 30 fps (Aplio 500) and 60 fps (Artida/Aplio 500)...

Although aortic root replacement using a composite graft including the Bentall operation is the treatment of choice for a diseased aortic valve and root dilatation, composite graft endocarditis can occur as a life-threatening complication with a high mortality rate. When aortic pseudoaneurysm occurs due to composite graft endocarditis, it usually indicates that saccular bulging of the surrounding tissue of the composite graft is present. Furthermore, another sign and a clue of the diagnosis of pseudoaneurysm is the collapse of the composite graft due to the outer compression pressure of the leaking blood flow...

Interrupted aorta is a very rare heart defect in which there is a gap between the ascending and the descending thoracic aorta. It is usually associated with other cardiac anomalies, including ventricular septal defect, ductus arteriosus, and truncus arteriosus. Severe cases present with serious complications such as hypertension, heart failure, or intracranial hemorrhage. Neurological complications are very rare form of presentation and commonly associated with intracranial aneurysms. We have reported a case of interrupted aorta who presented with transient ischemic attack due to thrombus formation in the interrupted segment of the aorta...

BACKGROUND: Even though the tricuspid annulus (TA) is anatomically and functionally related to right atrioventricular dependence and tricuspid annular plane systolic excursion (TAPSE) is a well-known measure of right ventricular (RV) systolic function, there is paucity of data regarding the potential impact that right atrial (RA) size and function have on TAPSE. Hence, we sought to determine whether RA volumetric and longitudinal measures affect TAPSE in patients with chronic pulmonary hypertension (cPH)...

Hypoplasia of the posterior mitral valve leaflet (PMVL) is a rare congenital heart disease, usually presenting in infancy and childhood with severe mitral regurgitation, either in isolation or associated with other cardiac lesions. We report a case of a 69-year-old woman with recent-onset exertional dyspnea and severe mitral regurgitation. Two- and three-dimensional transesophageal echocardiography showed severe hypoplasia of the PMVL, confirmed by surgical inspection.

INTRODUCTION: Peak exercise echocardiogram (EEcho) has shown reasonable sensitivity and specificity in detecting significant coronary artery disease (CAD). The objective was to evaluate the prognostic value of EEcho in patients hospitalized for acute chest pain (CP) and its additional prognostic information regarding exercise electrocardiogram test (EECG). METHODS: Prospective observational study performed between May 2011 and September 2013, including 250 patients consecutively admitted for acute CP with normal cardiac biomarkers and nondiagnostic electrocardiogram...

BACKGROUND/OBJECTIVES: In severe aortic stenosis (AS), deterioration of left ventricular ejection fraction (LVEF) to <50% is an AHA/ACC class I indication for valve replacement, regardless of symptoms. Controversy surrounds prognosis of low-flow AS compared to normal-flow, and no study has examined LVEF deterioration. We compared factors associated with LVEF deterioration (to <50%) and clinical outcomes. METHODS: Consecutive subjects with low-flow (stroke volume index <35 mL/m(2) , n=56) and normal-flow (n=72) severe AS (aortic valve area <1 cm(2) ) with preserved LVEF (>50%) and with paired echocardiography were studied...

BACKGROUND: Few studies have analyzed changes in left atrial (LA) function associated with different phenotypes of asymmetric hypertrophic cardiomyopathy (HCM). We sought to demonstrate the association of impairments in LA function with disease phenotype in patients with obstructive and nonobstructive HCM. METHODS: From Stanford Cardiomyopathy Registry, we randomly selected 50 age-/sex-matched healthy controls, 35 patients with nonobstructive HCM (HCM 1), 35 patients with obstructive HCM (HCM 2), and 35 patients with obstructive HCM requiring septal reduction therapy (HCM 3)...

BACKGROUND: Right ventricular (RV) pressure overload in the context of pulmonary stenosis (PS) has a much better prognosis than in the context of idiopathic pulmonary arterial hypertension (iPAH), which may be related to differences in global and regional RV remodeling and systolic function. We compared RV mechanics in children with PS to those with iPAH, aiming to identify mechanisms and markers of RV dysfunction. METHODS: Eighteen controls, 18 iPAH and 16 PS patients were retrospectively studied...

BACKGROUND: Impaired relaxation filling pattern in the presence of preserved left ventricular ejection fraction is a common finding which is ascribed to early diastolic dysfunction. We thought to determine the distribution of various markers of systolic and diastolic dysfunction in these patients. METHODS: A total of 106 patients were included in this retrospective observational study. Diastolic dysfunction was defined using the American Society of Echocardiography recommendations ("50% rule")...

We reviewed echocardiography literature for the assessment and management of semilunar valve disease in children. A search was performed within the National Library of Medicine using the keywords aortic stenosis (AS), aortic regurgitation, pulmonary stenosis (PS), and pulmonary regurgitation in children. The search was further refined adding the keywords-pediatric, neonates, echocardiographic definition, classification, evaluation. Thirty-eight studies were included. For stenotic lesions, there were sufficient consistencies between Doppler and invasive gradients (especially for PS), while other quantitative parameters used in adults showed significant limitations when applied to children...

Left atrial dissection is a rare entity, mostly occurring after mitral valve surgery, with only a few cases described after myocardial infarction. The authors report a case of a 60-year-old man who presented with an inferior myocardial infarction, complicated with pseudoaneurysm of basal segment of left ventricular inferior wall, which expanded through the mitral ring to left atria, causing left atrial free wall dissection. The left ventriculo-atrial communication through the pseudoaneurysm caused major para-mitral regurgitation and the development of acute heart failure...

A 58-year-old male with a history of a soft tissue sarcoma in remission presented with a 2 weeks history of progressive dyspnea. Transthoracic echocardiography showed right ventricular dilation; right ventricular systolic pressure (RVSP) of 110 mm Hg, and a lobulated mass in the right ventricular outflow tract (RVOT) causing obstruction. Microbubble contrast was administered showing perfusion within the mass, which suggested malignancy. A CT pulmonary angiogram (CTPA) confirmed the presence of the mass in the RVOT without evidence of pulmonary embolism...

INTRODUCTION: Dextro-transposition of the great arteries (d-TGA) patients is at high risk of developing right ventricular dysfunction and tricuspid regurgitation in adulthood. Determining the relation between echocardiographic parameters, N-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels and the New York Heart Association (NYHA) functional class may help determining the best time to operate them. METHODS: Patients with simple d-TGA operated in infancy with an atrial switch procedure (Mustard or Senning operation) were followed up in our Adult Congenital Heart Disease Unit...

Retroaortic course of coronary artery is a relative contraindication for device closure of an atrial septal defect. In this brief report, we demonstrate, for the first time, inferior aortic recess mimicking retroaortic left circumflex coronary artery in a patient with atrial septal defect. This distinction is important to avoid spurious diagnosis of anomalous coronary artery denying patient a chance of nonsurgical closure of atrial septal defect.
