Background Parametric T1 mapping currently allows non-invasive estimation of diffuse left-ventricular fibrosis. Imaging for T1 mapping is usually acquired during the diastolic phase. However, in tachycardia and arrhythmia, diastasis is short and imaging challenging. Conversely, systolic T1 mapping might offer an advantage and further enable more accurate ROI delineation for T1 maps as the myoca...

Diastolic and systolic left ventricular (LV) dysfunction often significantly contribute to disabling symptoms in familial hypertrophic cardiomyopathy (FHC). This study compares regional LV function (midwall circumferential strain) during systole and diastole in eight FHC patients and six normal volunteers (NVs) using MR tagging. A prospectively-gated fast gradient-echo sequence with an echo-tra...

INTODUCTION Congestive heart failure (CHF) is a major cause of morbidity and mortality in the western world and is the leading cause of hospitalization in older patients (1). However, over one third of patients with decompensated heart failure have normal left ventricular (LV) systolic function (heart failure with normal ejection fraction (HFNEF)). This condition occurs when LV filling and rela...

OBJECTIVE Examination of left ventricular function and conduction abnormalities in myotonic dystrophy. DESIGN Twelve patients (median age, 13.7 years) with myotonic dystrophy had detailed electrocardiography and echocardiography performed. Echocardiographic parameters were compared with body surface area (BSA) matched median normal values. RESULTS Fractional shortening was slightly reduced ...

Introduction The formation of vortices during left ventricular (LV) filling (Fig. 1) has been noted in several investigations using phase contrast (PC) MRI [1,2], but the effect of diastolic dysfunction (DD) on vortex formation has not been investigated. We hypothesize that impaired relaxation (IR) and increased stiffness of the LV wall in DD, will substantially alter the kinetics of the vortic...

The goal of the research is to investigate the special effect of ovarian-menstrual cycle phases on the level of women's blood pressure and characteristics of Mayer waves. 77 women aged 18-19 were tested under condition close to the state of basal metabolism in follicular phase (I), ovulation (II) and luteal phase (III) of ovarian-menstrual cycle. In phases II and III, the increase of mean and d...

There are frequent clinical Cases in Cardiological practice when cardiac failure develops together with normal systolic function of left ventricle. In these patients after revealing the diastolic dysfunction the heart diastolic failure is diagnosed, but in frequent cases this diagnosis is based on exclusion method. According to Framingham data the number of patients with clinically manifested d...

BACKGROUND The aim of the study was to determine the relationship between the rate of peak early mitral inflow velocity and the peak early diastolic mitral annular tissue velocities in normal controls and to compare them with subjects with diastolic dysfunction. METHODS The relationship between early passive diastolic transmitral flow and peak early mitral annular velocity in the normal and i...

The performance of an ultrasound sphygmomanometer (Arteriosonde 1217) has been compared with that of the London School of Hygiene and Tropical Medicine and Hawksley sphygmomanometers. The Arteriosonde gave closely similar values of systolic blood pressure of the other instruments but diastolic blood pressure lay midway between phase 4 and phase 5 of the Korotkoff sounds. Observers using the Art...

Introduction A single-phase 3d steady-state-free precession whole heart approach with respiratory navigator gating and ECG triggering (3d SSFP) is now frequently used for diagnostic imaging in children with congenital heart disease (CHD). However, certain cardiac structures may be better assessed during the systolic and others in the diastolic rest period. Therefore, a previously described dual...
