conclusions the vibratory innocent murmur is associated with the presence of left ventricular false tendon and higher left ventricular outflow tract velocity. the presence of the left ventricular false tendon was somewhat associated with decreased early diastolic myocardial velocity. normal left ventricular systolic and diastolic function can be used as a reassurance in cases with the vibratory...

BACKGROUND Previous studies have reported an important role for right ventricular function in the pathophysiology of the low cardiac output state that can accompany right ventricular infarction. Some studies have suggested that right ventricular distensibility impairs right ventricular filling and stroke output; others have demonstrated that the pericardium can mediate depressed left ventricula...

To clarify the basis of increased left ventricular (LV) end-diastolic pressure associated with isometric exercise, LV diastolic and systolic function were examined in 25 patients during sustained handgrip. During handgrip, average systemic arterial mean pressure increased by 20 mm Hg, and LV systolic pressure rose by 31 mm Hg, though in five patients, no increase in mean arterial or LV systolic...

Background 4D flow CMR analysis of right ventricular (RV) diastolic inflow has demonstrated vortical formations at tips of the tricuspid valve during the deceleration phase of early filling (E wave) (Figure 1). Vorticity can measure the rotation of these vortices and may represent a novel way to assess RV diastolic function. We aimed to determine if right heart vorticity identified right ventri...

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...

Introduction: The correlation between right and left ventricular ejection fractions (RVEF and LVEF, respectively) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The aim of the present study was to compare LVEF and RVEF in patients with ischemic heart disease. RVEF and LVEF were measured by Cardiovascular Magnetic Resonance (CMR) imaging. Materials a...

introduction: pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. we have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. materials a...

OBJECTIVE To evaluate the impact of chronic obstructive pulmonary disease (COPD) on left ventricular (LV) diastolic function in hospitalized elderly patients. METHODS This was a case-control observational study of 148 consecutive hospitalized elderly patients (≥65 years old): 73 subjects without COPD as controls and 75 patients with COPD. Mild-to-moderate COPD was defined as stages 1 and 2, w...

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...
