La conciencia de la enfermedad cardiovascular (ECV) en mujeres es crucial para prevenir futuros eventos cardiovasculares. En Chile, percepción sobre ECV baja.
External cephalic version (ECV) is the manipulation of the fetus, through the maternal abdomen, to a cephalic presentation. This guideline summarises the evidence regarding the routine use of ECV for breech presentation. The rationale behind ECV is to reduce the incidence of breech presentation at term and therefore the associated risks, particularly of avoidable caesarean section. The evidence...
Background Amyloidotic cardiomyopathy (AC) in Hereditary Transthyretin Amyloidosis (ATTR) determines prognosis and treatment options. Cardiac Magnetic Resonance (CMR) has shown its utility in the diagnosis and characterization of AC. Moreover, CMR T1 mapping techniques are useful to assess myocardial extracellular volume (ECV) fraction in AC. We hypothesized that ECV allows identification of AC...
PURPOSE Myocardial T1 relaxation time (T1 time) and extracellular volume fraction (ECV) are altered in patients with diffuse myocardial fibrosis. The purpose of this study was to perform an intra-individual assessment of normal T1 time and ECV for two different contrast agents. METHODS A modified Look-Locker Inversion Recovery (MOLLI) sequence was acquired at 3 T in 24 healthy subjects (8 men...
BACKGROUND Initial success of electrical cardioversion (ECV) of atrial fibrillation (AF) has been reported in several studies as 50%-90%, of which only 50% patients remain in sinus rhythm (SR) at the end of one year. We conducted this study to see if outcomes of other trials are applicable in managed care setting. METHODS We conducted a retrospective study in 370 consecutive patients who unde...
AIMS (i) To establish the test-retest reproducibility of myocardial T1 and extracellular volume (ECV) fraction measurement in asymptomatic patients with moderate-severe aortic stenosis (AS), (ii) to compare reproducibility using motion-corrected (MOCO) parametric T1 maps for analysis vs. full MOLLI series of images, and (iii) to compare T1 and ECV between patients and age-matched controls. ME...
OBJECTIVE To determine the care pathways and implications of offering mothers the choice of external cephalic version (ECV) at term for singleton babies who present with an uncomplicated breech pregnancy versus assisted breech delivery or elective caesarean. DESIGN A prospective observational audit to construct a decision analysis of uncomplicated full term breech presentations. SETTING The...
BACKGROUND Gadolinium (Gd) Extracellular volume fraction (ECV) by Cardiovascular Magnetic Resonance (CMR) has been proposed as a non-invasive method for assessment of diffuse myocardial fibrosis. Yet only few studies used 3 T CMR to measure ECV, and the accuracy of ECV measurements at 3 T has not been established. Therefore the aims of the present study were to validate measurement of ECV by MO...
Background Quantitative extracellular volume (ECV) estimates based on T1 mapping have potential for characterizing cardiomyopathies with diffuse fibrosis and edema [1,2]. An unsupervised approach for generating pixel-wise ECV maps was recently introduced [3]. In this work we extend the algorithms to include saturation recoverybased T1 mapping and present an inline implementation of these method...
Background Measurements of myocardial extracellular volume (ECV) through cardiac magnetic resonance (CMR) based T1 mapping allow for non-invasive quantification of diffuse myocardial fibrosis. The evaluation of the right ventricle (RV), often mainly affected in congenital heart disease (CHD), is complicated by its typical morphologic characteristics a thin myocardium and a distinct trabeculatio...
