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...

Evaluate whether endothelial overexpressing of the bradykinin B1 receptor could be associated with altered left ventricular and myocardial performance. Echocardiography and hemodynamic were employed to assess left ventricular morphology and function in Sprague-Dawley transgenic rats overexpressing the endothelial bradykinin B1 receptor (Tie2B1 rats). The myocardial inotropism was evaluated on papillary muscles contradicting in vitro. In Tie2B1 animals, an enlarged left ventricular cavity and lower fractional shortening coupled with a lower rate of pressure change values indicated depressed left ventricular performance...

It is unknown whether physiological ageing also goes along with electromechanical asynchrony of contraction. Aim of the study was to evaluate synchrony of contraction in older people with ("non-healthy") or without ("healthy") evidence for structural cardiac disease. In 547 persons (age 76.7+/-5.5 years, 306 male, 241 female) recruited from a population-based cohort of the ActiFE-Um study including a random sample of people >/= 65 years old living in the region of Ulm, Germany, various PW- and TDI-Doppler based markers for asynchrony were obtained by echocardiography...

Cardiotoxicity is an important complication of several cancer therapeutic agents. Several well established and newer anticancer therapies such as anthracyclines, trastuzumab and other HER2 receptor blockers, antimetabolites, alkylating agents, tyrosine kinase inhibitors (TKIs), angiogenesis inhibitors, and checkpoint inhibitors are associated with significant cardiotoxicity. Cardiovascular imaging employing radionuclide imaging, echocardiography and magnetic resonance imaging are helpful in early detection and prevention of overt heart failure secondary to cardiotoxicity of cancer therapy...

Patients with Friedreich's ataxia (FA) are at an increased risk of developing diabetes mellitus and glucose intolerance. Diabetes usually develops many years after the initial presentation. We report an 8-year-old girl who initially presented with diabetic ketoacidosis and was treated as a case of insulin-dependent diabetes mellitus. Around a year later, she developed gait problems and ataxia. Cardiac involvement was detected on echocardiography. Genetic testing confirmed the diagnosis of FA. FA should be a diagnostic consideration in children presenting with diabetes and neurological issues, even with early presentation of the former...

Compared with traditional exercise tests, cardiopulmonary exercise testing (CPET) provides a thorough assessment of exercise integrative physiology involving the pulmonary, cardiovascular, muscular, and cellular oxidative systems. Due to the prognostic ability of key variables, CPET applications in cardiology have grown impressively to include all forms of exercise intolerance, with a predominant focus on heart failure with reduced or with preserved ejection fraction. As impaired cardiac output and peripheral oxygen diffusion are the main determinants of the abnormal functional response in cardiac patients, invasive CPET has gained new popularity, especially for diagnosing early heart failure with preserved ejection fraction and exercise-induced pulmonary hypertension...

BACKGROUND: Tenascin-C (TNC) is a highly conserved matricellular protein with a distinct expression pattern during development and disease. Remodeling of the left ventricle (LV) in response to pressure overload leads to the re-expression of the fetal gene program. OBJECTIVES: The aim of this study was to investigate the function of TNC in cardiac hypertrophy in response to pressure overload. METHODS: Pressure overload was induced in TNC knockout and wild-type mice by constricting their abdominal aorta or by infusion of angiotensin II...

The aim of this European Heart Rhythm Association (EHRA) survey was to evaluate clinical practice regarding cardio-oncologic patients, with special focus on patients with cardiac implantable electronic devices (CIEDs) planned for anticancer radiotherapy (RT), among members of the EHRA electrophysiology research network. Of the 36 responding centres, 89% managed patients who were diagnosed or treated oncologically, and this diagnosis affected 1-5% of cardiovascular patients in majority of centres (57%). The main side effects of anticancer therapy in patients treated by cardiologists were thromboembolic complications and left ventricular dysfunction (both reported as 'frequent' by 43% of the centres)...

PURPOSE: Heart failure (HF) is a multifactorial entity that combines derangements in both systolic and diastolic function. The relationship between systolic and diastolic function and exercise capacity is not fully understood. We sought to determine the mechanisms linking cardiac function and exercise tolerance in patients with HF. METHODS: One hundred fifty-six subjects with different cardiac function levels were included in the study. Subjects' 2D echocardiographic, 3D speckle tracking echocardiographic, and cardiopulmonary exercise testing (CPET) data were collected...

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...

Right ventricle (RV) is considered a neglected chamber in cardiology and knowledge about its role in cardiac function was mostly focused on ventricular interdependence. However, progress on the understanding of myocardium diseases primarily involving the RV led to a better comprehension of its role in health and disease. In Chagas disease (CD), there is direct evidence from both basic and clinical research of profound structural RV abnormalities. However, clinical detection of these abnormalities is hindered by technical limitations of imaging diagnostic tools...

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%...

OBJECTIVE: Novel echocardiographic techniques, such as speckle tracking echocardiography (STE) and tissue Doppler imaging, are sensitive tools for assessing left ventricular (LV) performance. LV global longitudinal strain (GLS), assessed by STE, is a sensitive marker of myocardial systolic function. Cardiovascular complications in patients with Cushing's disease (CD) determine a higher mortality than that in an age- and gender-matched population. Cardiac systolic dysfunction may be detected in early stages by STE...

The description of totally anomalous systemic venous connection is limited to case reports. In this review, we seek to clarify anatomic, physiologic, and hemodynamic aspects of this extremely rare anomaly. We also present findings of two patients in whom connection of all the systemic veins was anomalous. In the first patient, with usual atrial arrangement, all systemic veins, including the coronary sinus, were connected anomalously to the morphologically left atrium. Limited left-to-right shunt across an atrial septal defect provided the only source of blood flow to the lungs...
