History and clinical findings We present a 31-year old woman with a 6-year history of cutaneous lupus erythematosus (CLE) who presented to the emergency room with typical chest pain. ECG and transthoracic echocardiography were normal. Her working diagnosis of pericarditis was made due to systemic progression of her lupus erythematosus (LE). Treatment with NSAIDs was initiated and her immunosuppressive regimen intensified. The patient was discharged after resolution of her symptoms. A week later, the patient was seen at the rheumatology clinic with recurrence and aggravation of her symptoms...

BACKGROUND: Dexmedetomidine (DEX) has been used for sedation in young infants and children undergoing transthoracic echocardiography (TTE). The median effective dose of intranasal DEX has not been described for postcardiac surgery children. Postcardiac surgery children could require more DEX to achieve satisfactory sedation for TTE examination than children suspected of congenital heart disease. OBJECTIVES: To study whether postcardiac surgery children need a larger dose of DEX for TTE than normal children...

Enlarging or "cracking" a surgical stented bioprosthetic valve during valve-in-valve transcatheter aortic valve implantation (TAVI) increases orifice area, reducing transvalvular energy losses. We demonstrate that TAVI with valve cracking can be used to treat paravalvular leak (PVL) while providing optimal aortic valve physiology. A 61-year-old woman with a history of aortic valve replacement with a stented bioprosthesis presented with heart failure. Transthoracic echocardiography revealed severe prosthetic aortic valve stenosis with PVL and severe regurgitation...

The cardio-ankle vascular index (CAVI) is a measure of global arterial stiffness. We hypothesized that CAVI is associated with left ventricular (LV) function and geometry in individuals without structural heart disease. We measured CAVI in 600 participants (mean age 60.3±14.6 years, 54% men) without history of atherosclerotic cardiovascular disease who were referred for transthoracic echocardiography. Linear regression analysis was used to assess the association of CAVI with LV function (peak mitral annular systolic s' and early diastolic velocity e') and structure (LV mass index (LVMI) and relative wall thickness (RWT))...

OBJECTIVE: Several studies have been conducted regarding the effects of coal mining on the respiratory system. However, there is a lack of data concerning potential effects of coal mining on the cardiovascular system. In this study, we aimed to evaluate the potential subclinical right and left ventricular dysfunction in coal miners. METHODS: This single-center, prospective study included a total of 102 patients. Patient and control groups consisted of 54 coal miners and 48 healthy men, respectively...

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...

Persistent left superior vena cava (LSVC) is a rare congenital anomaly. Its prevalence in the general population is 0.1 to 0.5%. LSVC is 5 times rarer when accompanied by an absence of the right superior vena cava (RSVC). We present the case of a 54-year-old man who carries a persistent LSVC without RSVC. Clinically, this patient presented a regular bradycardia at 40 per minute associated with a heart failure syndrome. The electrocardiogram diagnosed a complete atrioventricular block and transthoracic echocardiography showed dilated left heart cavities and a left ventricular ejection fraction of 50%...

Congenital left atrial appendage aneurysm is a rare condition caused by dysplasia of the atrial muscles. We report a case of a 14-year-old boy, with a 5-month history of cough and in sinus rhythm. Transthoracic echocardiography and computerized tomographic angiography confirmed the aneurysm of the left atrial appendage which was resected through median sternotomy on cardiopulmonary bypass. This case is presented not only for its rarity but also for its atypical clinical presentation.

BACKGROUND: The human aorta dilates with advancing age. However, the association between progressive aortic dilation with aging and cardiac remodeling has not been established in studies of community-dwelling adults. The aim of this study was to test the hypothesis that there would be a relationship between aortic size increase over the early adult life span with left ventricular (LV) structural remodeling and subclinical LV dysfunction in middle age, even in the absence of overt cardiovascular and valvular disease...

BACKGROUND AND PURPOSE: An appropriate inflammatory response is necessary for cardiac healing after acute myocardial infarction (MI). Resolvin E1 (RvE1) is an anti-inflammatory and pro-resolution lipid mediator derived from eicosapentaenoic acid. The purpose of this study was to investigate the potential effects of RvE1 on cardiac function recovery after MI in mice. EXPERIMENTAL APPROACH: Acute MI was induced by surgical ligation of the left anterior descending artery (LAD) in mice...

A healthy 19-year-old man was referred to our hospital due to an elongated left heart border on chest radiograph. Transthoracic echocardiography showed a posteriorly deviated left ventricular apex, increased right ventricular dimension, and hypokinesis of the interventricular septum. Pulsed Doppler echocardiogram revealed a triphasic mitral inflow pattern. Myocardial longitudinal strain rate imaging revealed that the early diastolic strain rate abruptly decreased to a negative value and then became positive at the left ventricular apex...

Echocardiography is an excellent noninvasive imaging modality for evaluation and follow-up of cardiac lesions, especially coronary artery changes occurring as a result of Kawasaki disease. The information obtained has prognostic implications and can be complemented with other modes of imaging for risk stratification and optimization of both medical and interventional therapy. The aim of this article is to describe the time line of echocardiographic follow-up of patients affected with Kawasaki disease. The classification of coronary artery changes and transthoracic echocardiographic views recommended for detailed evaluation of the coronary arteries are delineated in detail in this report...

Prepartum or postpartum right ventricular thrombosis (RVT) is an exceedingly rare and potentially lethal phenomenon in pregnancy. We here report a case of a pregnant patient with near term pregnancy admitted for dyspnea, amniotic fluids discharge and labor pain in a gynecology center that an eight-month dead fetus was diagnosed and delivered vaginally by induction. A post delivery period was complicated by aggravation of her dyspnea and pleuritic chest pain that she referred for further evaluation in our cardiac center...

Left atrium (LA) size is a well-studied predictor of atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). Yet, there is still little agreement on the best imaging technique to size the LA, and on the most appropriate sizing parameter. Volumetric assessment of LA with three-dimensional rotational angiography (3DRA LA volume index) might be a valid alternative to the commonly used transthoracic echocardiography (TTE LA volume index). The aim of our study was to investigate whether LA volume by 3DRA at the time of PVI is able to predict the risk of atrial fibrillation recurrence...

The precision of echocardiography in estimating pulmonary pressures has been debated. A value of right atrial pressure (RAP) is needed for pulmonary pressure estimation, and it could be partly responsible for the estimation error. Several schemes based on the inferior vena cava (IVC) are commonly used in clinical practice and in experimental studies for RAP estimation. However, the majority lack proper validation, and thus far, no study has compared them all. In this prospective, blinded study, a comprehensive transthoracic echocardiography was performed on 200 patients referred for right heart catheterization...
