Background: Elevated plasma levels of Lipoprotein(a) [Lp(a)] are recognized as a significant risk factor for atherosclerotic vascular disease. However, there are limited data regarding association between Lp(a) and recurrent heart failure (HF) in patients with chronic HF caused by coronary heart disease (CHD). Objective: Elevated levels of Lp(a) might have a prognostic impact on recurrent HF in patients with chronic HF caused by CHD. Methods: A total of 309 patients with chronic HF caused by CHD were consecutively enrolled in […]

Background: Thoracic bioreactance (TB), a noninvasive method for the measurement of cardiac output (CO), shows good test-retest reliability in healthy adults examined under research and resting conditions. Objective: In this study, we evaluate the test-retest reliability of CO and cardiac power (CPO) output assessment during exercise assessed by TB in healthy adults under routine clinical conditions. Methods: 25 test persons performed a symptom-limited graded cycling test in an outpatient office on two different days separated by one week. Cardiorespiratory (power […]

Abstract Background: Recent studies suggest that left atrial (LA) late gadolinium enhancement (LGE) can quantify the underlying tissue remodeling that harbors atrial fibrillation (AF). However, quantification of LA-LGE requires labor-intensive magnetic resonance imaging acquisition and postprocessing at experienced centers. LA intra-atrial dyssynchrony assessment is an emerging imaging technique that predicts AF recurrence after catheter ablation. We hypothesized that 1) LA intra-atrial dyssynchrony is associated with LA-LGE in patients with AF and 2) LA intra-atrial dyssynchrony is greater in patients with […]

Abstract Background: Few reports exist on the relationship of the left ventricular diastolic dysfunction (LVDD) with its most important features including enlargement of the left atrium and left ventricular hypertrophy (LVH), and with the right ventricular (RV) function. Objective: To determine the correlation between the left atrial size and the RV function and dimensions in patients with and without LVDD and LVH. Methods: Fifty patients were included, 25 (40% men) of them with LVDD, aged 67.1 ± 10.6 years (study […]

Introduction Anomalous left coronary artery arising at the right sinus of Valsalva is a relatively rare congenital cardiac anomaly that can cause myocardial ischemia. It can follow one out of five aberrant courses: interarterial, subpulmonic, pre-pulmonic, retroaortic, or retrocardiac. We present the case of a young patient with an anomalous left coronary artery arising at the right sinus of Valsalva with severe stenosis and hypoplasia throughout the interarterial segment, which hampered corrective surgery. The timely detection and adequate treatment of […]

A-81-years old woman was admitted after an episode of ventricular tachycardia with hemodynamic instability converted after electrical cardioversion (). Past medical history was significant for poorly differentiated squamous cell carcinoma of left parathyroid, diabetes and hypertension. […]

Abstract Background: Although right ventricular (RV) dysfunction in pulmonary diseases has been associated with increased morbidity, tools for RV dysfunction identification are not well defined. Objective: The aim of this study was to evaluate the magnitude of RV dysfunction by means of speckle tracking echocardiography (STE) in patients with chronic obstructive pulmonary disease (COPD) and to investigate whether STE could be used as an index of RV improvement after a pulmonary rehabilitation (PR) program. Methods: Forty-six patients with COPD undergoing […]

Abstract Background: Unstable angina (UA) is a common cause of hospital admission; risk stratification helps determine strategies for treatment. Objective: To determine the applicability of two-dimensional longitudinal strain (SL2D) for the identification of myocardial ischemia in patients with UA. Methods: Cross-sectional, descriptive, observational study lasting 60 days. The sample consisted of 78 patients, of which fifteen (19.2%) were eligible for longitudinal strain analysis. The value of p < 0.05 was considered significant. Results: The group of ineligible patients presented: a [...]

Abstract Background: Acutely decompensated heart failure (ADHF) presents high morbidity and mortality in spite of therapeutic advance. Identifying factors of worst prognosis is important to improve assistance during the hospital phase and follow-up after discharge. The use of echocardiography for diagnosis and therapeutic guidance has been of great utility in clinical practice. However, it is not clear if it could also be useful for risk determination and classification in patients with ADHF and if it is capable of adding prognostic […]

A 32-year-old female with a 2-year history of chest distress was admitted to our department due to exacerbation for 3 days. On physical examination, we found fixed splitting second heart sounds on the patient’s pulmonic area. An echocardiography was performed and showed a 15-mm atrial septal defect of the inferior vena cava type. After obtaining the patient’s consent, a three-dimensional printing cardiac model was printed out. We tried various sizes of ASD occluders on the model to completely cover the […]
