Endovascular treatment of stroke in children under 2 years with heart failure and ventricular assist device.
CONCLUSION: As a result of the difficulty in performing arterial puncture, the small vessel calibre and the limitation in the use of iodated contrast, there are certain limitations to endovascular treatment of strokes in children that can lead to complications. A multidisciplinary approach to managing such cases would be helpful. PMID: 31072251 [PubMed - as supplied by publisher]

Design, Implementation, and Validation of a Pulsatile Heart Phantom Pump
In this study, we aimed to develop an affordable pulsatile pump and an artificial circulatory system to simulate the blood flow for validation purposes. Initially, the prerequisites for the phantom were pulsating flow output equal to that of the human cardiac pulse pattern; the flow pattern of the mimicked cardiac output should be equal to that of a human, a variable stroke volume (40 –120 ml/beat), and a variable heart rate (60–170 bpm). The developed phantom setup was tested with CT scanner. A washout profile was created based on the image intensity of the selected slice. The test was successful for a heart rate of...

Hypertrophic Cardiomyopathy Present and Future, With Translation Into Contemporary Cardiovascular Medicine
Hypertrophic cardiomyopathy (HCM) is a common inherited heart disease with diverse phenotypic and genetic expression, clinical presentation, and natural history. HCM has been recognized for 55 years, but recently substantial advances in diagnosis and treatment options have evolved, as well as increased recognition of the disease in clinical practice. Nevertheless, most genetically and clinically affected individuals probably remain undiagnosed, largely free from disease-related complications, although HCM may progress along 1 or more of its major disease pathways (i.e., arrhythmic sudden death risk; progressive heart failu...

Cardiovascular magnetic resonance parameters associated with early transplant-free survival in children with small left hearts following conversion from a univentricular to biventricular circulation
Background: We sought to identify cardiovascular magnetic resonance (CMR) parameters associated with successful univentricular to biventricular conversion in patients with small left hearts. Methods: Patients with small left heart structures and a univentricular circulation who underwent CMR prior to biventricular conversion were retrospectively identified and divided into 2 anatomic groups: 1) borderline hypoplastic left heart structures (BHLHS), and 2) right-dominant atrioventricular canal (RDAVC). The primary outcome variable was transplant-free survival with a biventricular circulation. Results: In the BHLHS group (nâ€...

Quantitative computed tomography of pulmonary emphysema and ventricular function in chronic obstructive pulmonary disease patients with pulmonary hypertension.
CONCLUSION: The study revealed that percent emphysema is correlated with RV dysfunction among COPD patients with PH. Based on our findings, percent emphysema can be considered for use as an indicator to predict the severity of right ventricular dysfunction among COPD patients. PMID: 25469102 [PubMed - in process]

Cross-modality Accuracy of Dual-step, Prospectively Electrocardiography-triggered Dual-source Computed Tomorgaphy Compared With Same-day Echocardiography and Cardiac Magnetic Resonance Imaging in the Follow-up of Heart-transplant Patients
Purpose: An accurate evaluation of left ventricular volumes, mass, and ejection fraction (EF) and an early exclusion or detection of significant coronary artery disease or cardiac allograft vasculopathy are mandatory for clinical management and prognosis assessment of heart-transplanted patients (HTP). The purpose of this article was to evaluate the role of dual-step prospective electrocardiography-triggered Dual-Source CT (pECGdual-step-DSCT) in HTP for the assessment of left-ventricular function, in comparison with echocardiography (echo) and cardiac magnetic resonance (CMR) performed on the same day, and of the corona...

Echocardiographic determination of pulmonary arterial capacitance
AbstractA growing body of evidence has demonstrated that pulmonary arterial capacitance (PAC) is the strongest hemodynamic predictor of clinical outcomes across a wide spectrum of cardiovascular disease, including pulmonary hypertension and heart failure. We hypothesized that a ratio of right ventricular stroke volume (RVOT VTI) to the associated peak arterial systolic pressure (PASP) could function as a reliable non-invasive surrogate for PAC. We performed a prospective study of patients undergoing simultaneous transthoracic echocardiography and right heart catheterization (RHC) for various clinical indications. Measureme...

Prognostic value of left atrial strain in patients with moderate asymptomatic mitral regurgitation
AbstractFor patients with asymptomatic mitral regurgitation (MR), the criteria identifying the groups at higher-risk and their clinical outcome are still uncertain. Therefore, in these patients, optimal time of surgery remains controversial. The purpose of this study was to compare left atrial (LA) strain to other echocardiographic left ventricular (LV) and LA parameters for the prediction of cardiovascular outcomes in patients with moderate asymptomatic MR. We enrolled 395 patients with primary degenerative moderate asymptomatic MR. Exclusion criteria were: history of atrial fibrillation, myocardial infarction, heart fail...
