CMR RV size assessment should include RV to LV volume ratio
Background The right ventricular (RV) size responds to many cardiopulmonary diseases characterized by chronic pressure and volume overload. Cardiovascular magnetic resonance (CMR) is considered the “gold-standard” for RV evaluation. The RV end-diastolic volume indexed to body surface area (RVEDVi) has been used for RV size assessment, but this parameter alone may not be sensitive enough to dete...
متن کاملOccult RV systolic dysfunction detected by CMR derived RV circumferential strain in patients with pectus excavatum
AIMS To investigate the right ventricular (RV) strain in pectus excavatum (PE) patients using cardiac magnetic resonance tissue tracking (CMR TT). MATERIALS AND METHODS Fifty consecutive pectus excavatum patients, 10 to 32 years of age (mean age 15 ± 4 years), underwent routine cardiac magnetic resonance imaging (CMR) including standard measures of chest geometry and cardiac size and function...
متن کاملVentricular volume and mass by CMR.
Cardiovascular magnetic resonance (CMR) is an ideal technique for investigating the cardiovascular system, because it has excellent high resolution differentiation of myocardium from blood pool and lung, and is free from xrays and noninvasive. This combined with high levels of accuracy, – 4] and reproducibility, – 9] has made it very popular in the research arena for the assessment of ventricul...
متن کاملPressure overloaded right ventricles: importance of trabeculae in evaluation of RV function by CMR
Background Cardiac magnetic resonance imaging (CMR) is the preferred method to evaluate right ventricular (RV) volumes and ejection fraction. In CMR-volumetry, trabeculae and papillary muscles can be either inor excluded from the blood volume and both methods are used throughout literature. This study aimed to determine the impact of trabeculae and papillary muscles on right ventricular (RV) vo...
متن کاملEvaluation of RV and LV mass by CMR and comparison to recipient heart following heart transplant; the first-ever CMR human autopsy study
Background CMR is considered the ‘gold standard’ for non-invasive LV and RV mass quantitation. To our knowledge, this information is solely based on GRE sequences, with its dependence on flow conditions having never been prospectively or retrospectively validated in humans undermining its credibility. SSFP, with intrinsic contrast dependent on T1/T2 characteristics, offers superior image contra...
