BACKGROUND: Clinicians rely on age- and size-specific measures of cardiac structures to diagnose cardiac disease. No universally accepted normative data exist for fetal cardiac structures, and most fetal cardiac centers do not use the same standards. The aim of this study was to derive predictive models for Z scores for 13 commonly evaluated fetal cardiac structures using a large heterogeneous population of fetuses without structural cardiac defects. METHODS: The study used archived normal fetal echocardiograms in representative fetuses aged 12 to 39 weeks...

BACKGROUND: The clinical presentation of Parkinson's disease (PD) includes a wide spectrum of non-motor features, including cardiovascular autonomic failure. OBJECTIVE: To evaluate cardiovascular autonomic status and cardiac functional capacity in drug-naïve PD patients. METHODS: 18 newly-diagnosed PD patients underwent laboratory cardiovascular autonomic function tests using power spectral analysis of the R-R interval, blood pressure (BP) short-term variability and non-invasive baroreflex sensitivity (BRS)...

Follow-up data and correlation of arrhythmias, electrocardiogram (ECG) changes, and cardiac function in anomalous left coronary artery from the pulmonary trunk or artery have not been previously studied. This is a retrospective single-center review of 44 anomalous left coronary artery from the pulmonary trunk or artery patients diagnosed between 1992 and 2014, at a median age of 3 months (3 days to 13 years). Clinical history, ECG, Holter, and echocardiogram data were reviewed. ECGs were reviewed for contiguous Q-or T-wave inversions, hypertrophy, bundle branch block, and axis deviation...

We have previously demonstrated the cardioprotective effects of ovarian hormones against adverse ventricular remodeling imposed by chronic volume overload. Here, we assess the estrogen receptor dependence of this cardioprotection. Four groups of female rats were studied: sham-operated (SHAM), volume overloaded (ACF), SHAM treated with estrogen receptor antagonist, ICI 182,780 (SHAM+ICI), and ACF treated with ICI. Cardiac function was assessed temporally using echocardiogram and tissue samples were collected at 5 days and 6 weeks post-surgery...

BACKGROUND: Point-of-care ultrasound often includes cardiac ultrasound. It is commonly used to evaluate cardiac function in critically ill patients but lacks the specific quantitative anatomic assessment afforded by standard transthoracic echocardiography (TTE). We developed the Focused Rapid Echocardiographic Examination (FREE), a hybrid between a cardiac ultrasound and TTE that places an emphasis on cardiac function rather than anatomy. We hypothesized that data obtained from FREE correlate well with TTE while providing actionable information for clinical decision making...

Although pulmonary function abnormalities in thalassaemia major (TM) were described in 1980, the pathogenetic mechanism is not clear and data are contradictory, probably because of study heterogeneity and the multifactorial nature of the pathogenesis. We retrospectively analysed 73 adult TM patients to evaluate the prevalence of pulmonary dysfunction in adult TM and investigate relationships with iron load. All patients underwent body plethysmography and carbon monoxide diffusion (DLCO) was assessed in 63, in addition to blood tests, echocardiogram and T2* myocardial and liver magnetic resonance imaging...

Diastolic dysfunction ranging from impaired relaxation of the left ventricle to heart failure with preserved ejection fraction (HFpEF) is a common finding in the cardiac surgery population. It is important for the peri-operative echocardiographer to have a developed understanding of the pathophysiology of diastolic dysfunction and the echocardiographic features that determine where on the spectrum of diastolic function and dysfunction a patient lies.

Introduction The significance of abnormal cardiac measures in asymptomatic females who harbor dystrophin gene mutations is controversial. Methods Echo-measures of ventricular function were compared with published norms in a cross-sectional study of 130 (age 39 ± 15.7 years) 'carriers' of Duchenne or Becker muscular dystrophy (DBMD). Correlations between cardiomyopathy (CM) and mutation, CK levels, age, and muscle symptoms were investigated. Results Depending on definition, CM prevalence was 3-33%. Ejection fraction (Simpson) was < 55% in 9 (13%) and < 40% in 2 (2...

INTRODUCTION: Twin-twin transfusion syndrome (TTTS) is the major cause for fetal demise in monochorionic diamniotic pregnancies. Estimated combined cardiac output (CCO) has not been studied in this setting. The primary aims of this study were to compare CCO in twin donor and recipient fetuses and assess differences in CCO before and after laser coagulation therapy. A secondary aim was to evaluate the relationship of CCO with perinatal mortality, defined as intrauterine or neonatal mortality (≤30 days of age) in fetuses that underwent laser coagulation therapy...

BACKGROUND: Dark blood imaging of the heart is conventionally performed using a breath-hold, dual-inversion Cartesian fast spin-echo pulse sequence. Our aim was to develop a faster, more flexible approach that would be less motion-sensitive and provide better image quality. For this purpose, we implemented a prototype radial balanced steady-state free precession (bSSFP) pulse sequence. METHODS: The study was approved by the institutional review board. Six healthy volunteers and 27 subjects undergoing clinically-indicated cardiovascular magnetic resonance (CMR) were imaged using dark blood Cartesian fast spin-echo and radial bSSFP...

OBJECTIVE: The traditional history and physical (H&P) is a poor screening modality to identify athletes at risk for sudden cardiac death. Although better than H&P alone, electrocardiograms (ECG) have also been found to have high false-positive rates. A limited portable ECG by a frontline physician (PEFP) performed during preparticipation physical examination (PPE) allows for direct measurements of the heart to more accurately identify athletes with structural abnormalities. Therefore, it is worthwhile to assess the feasibility of incorporating limited PEFP as part of PPEs...

BACKGROUND: Abdominal obesity and presence of the metabolic syndrome (MetS) are associated with cardiac abnormalities. Among those, left ventricular diastolic dysfunction (LVDD) is the most frequently encountered in clinical practice. Few studies evaluated the reversibility of LVDD by an approach promoting lifestyle modifications in abdominally obese subjects with MetS. METHODS: We assessed the impact of a 1-year lifestyle modification program combining nutritional and physical activity counseling on LVDD and metabolic profile of abdominally obese men with MetS...

OBJECTIVE: Microalbuminuria (MAU) and glomerular filtration rate (GFR) are the signs of subclinical kidney damage, independently predict cardiovascular morbidity and mortality. The aim of the study was to investigate the relative role of MAU, cardiac and vascular ultrasonography, carotid-femoral pulse wave velocity (PWV) for the detection of hypertensive target organ damage (TOD) and risk stratification. DESIGN AND METHOD: In 576 non-diabetic hypertensive patients without established cardiovascular or renal disease (291 male, 53...

OBJECTIVE: The recent results of the SPRINT study suggest that "intensive" reduction of systolic blood pressure (BP) (to less than 120 mmHg) might provide greater cardiovascular protection as compared to less intensive (< 140 mmHg) reduction of BP, at least in some subsets of patients. Only few studies, have investigated the possible effect of tight blood pressure control on indices of left ventricular hypertrophy, and have been mainly based on electrocardiography. Aim of our study was to evaluate cardiac organ damage according to "on treatment" blood pressure values in a large cohort of hypertensive patients undergoing echocardiography (2D, M-mode with conventional and tissue Doppler analysis)at the echo-lab of an ESH Excellence Centre in Italy...

Current Hypertension Guidelines emphasize the importance of assessing the presence of preclinical organ damage. In fact, an extensive evaluation of organ damage may increase the number of patients classified at high CV risk and therefore strongly influence the clinical management of patients. Hypertensive heart disease remains to date the form of organ damage for which there is the greatest amount of evidence of a strong independent prognostic significance. In the presence of a chronic pressure overload, a parallel addition of sarcomers takes place with an increase in myocyte width, which in turn increases left ventricular wall thickness; myocyte hypertrophy is also associated with apoptosis, collagen deposition and ventricular fibrosis with an impairment of coronary hemodynamics as well, thus profoundly influencing functional properties of the left (and right) ventricle...

We present a patient with asymptomatic apical hypertrophic cardiomyopathy (AHCM) who recently developed cardiac arrhythmias, and shortly discuss the diagnostic modalities, differential diagnosis, and treatment strategy for this condition. AHCM is a rare form of hypertrophic cardiomyopathy, which usually involves the apex of the left ventricle. AHCM can occur with varied presentations such as chest pain, palpitations, dyspnea, syncope, atrial fibrillation, myocardial infarction, embolic events, ventricular fibrillation, and congestive heart failure...

Intra-cardiac extension of tumour thrombus of follicular carcinoma of thyroid is uncommon. We report a case of advanced thyroid carcinoma where tumour thrombus was well profiled with CT scan and transesophageal echo images and extension was noted from SVC into right atrium, with clinical features of superior vena cava syndrome. The clinical significance of the "ring sign" is discussed.

Left atrial dissection is a very uncommon complication of cardiac surgery and usually causes significant hemodynamic compromise. Little is known about spontaneous dissection of the left atrium. Two patients, one middle-aged man and another elderly woman were evaluated following stroke. Routine trans-thoracic echocardiogram showed vertical division of the left atrium with both chambers communicating with each other through an orifice. Detailed trans-oesophageal echocardiographic study revealed dissection of the left atrium producing an additional false chamber (pseudo-aneurysm) placed posterior to the left atrial appendage and above the postero-lateral aspect of mitral annulus...
