A critical aspect of most cardiac catheterization procedures is the evaluation of myocardial function. At its simplest, this consists of a visual assessment of the left ventricular (LV) contractile pattern from the left ventriculogram, together with measurements of LV end-diastolic pressure. In laboratories where most patients have right-sided heart catheterization and cardiac output measuremen...

OBJECTIVE This study was designed to assess right ventricular systolic and diastolic function and its relationship with grade of hepatosteatosis (HS) in non-alcoholic fatty liver disease (NAFLD) patients using conventional and tissue Doppler echocardiography. METHODS NAFLD was diagnosed in 32 individuals (15 males, 17 females; 59% were grade I HS, 41% grade II-III HS) by means of ultrasonogra...

Background: Asthma is a predisposing factor for the development of atrial fibrillation. Asthma disturbs the electrophysiology in the right and left atrium. The aim of this study was to evaluate atrial electromechanical delay by coupling obtained from tissue Doppler imaging (TDI) in children. Methods: A cross-sectional study was conducted on 50 patients with Bronchial Asthma, compared with 50 hea...

We examined data on the mass, area and myocardial abnormality (scar or infarction) of the right ventricular free wall (RVFW) from 1500 consecutive dissections of hearts that came to autopsy. There were 447 hearts with associated coronary and ischemic heart disease (CAD) and 826 without CAD. RVFW mass was used as an index of hypertrophy (RVH) and RVFW area was used as an index of dilatation (RVD...

OBJECTIVES Elevated pulmonary vascular resistance occurs during the first days after birth in all newborn infants and persists in infants at risk for bronchopulmonary dysplasia (BPD). It is difficult to measure in a non-invasive fashion. We assessed the usefulness of the right ventricular index of myocardial performance (RIMP) to estimate pulmonary vascular resistance in very low birth weight i...
