Abstract Funding Acknowledgements Type of funding sources: None. Background Aortic regurgitation (AR) has been shown to have an impact on myocardial mechanics and recent studies have proved the value of global longitudinal strain (GLS) as an additional parameter in the assessment of …

Abstract Background Left ventricular (LV) hypertrophy is a known compensatory mechanism to pressure overload in aortic stenosis (AS) patients. However, by cardiac magnetic resonance (CMR) different patterns of LV adaptation are seen in this group of patients. Aim To describe the patterns …

Abstract Background In patients with severe aortic stenosis (AS), left ventricular (LV) remodeling is believed to be a compensatory adaptive process which should reverse after aortic valve intervention. However, this is not always the rule and remodeling persistence may negatively impact post-procedural …

Abstract Background Left ventricular (LV) hypertrophy is a common expected finding in aortic stenosis (AS) patients. Cardiac magnetic resonance (CMR) plays an important role as a non-invasive method for determining LV mass and volume, and to characterize the LV remodeling response in …

Proportionality of secondary mitral regurgitation (sMR) may be a key factor in deciding whether a patient may benefit from mitral intervention. The aim of this study was to evaluate the prognostic value of two different concepts of proportionality and assess their ability …

Abstract Funding Acknowledgements Type of funding sources: None. Background Chronic mitral regurgitation has been shown to promote left atrial (LA) dysfunction and remodeling. However, the significance of LA dysfunction in this setting has not been fully investigated. The aim of our study …

Abnormal diaphragmatic motion (ADM) due to phrenic nerve injury is a recognized complication of cardiac surgery and several diagnostic techniques can be used to determine the diagnosis. Due to its relationship with the diaphragm, cardiac kinetics is affected by the abnormal movement …

Abstract Background Left ventricular myocardial work (LVMW) is a novel method to evaluated left ventricular (LV) function using pressure-strain loops. It might correct global longitudinal strain (GLS) for afterload, being eventually useful to assess whether GLS reduction is due to reduced contractility …

Abstract Purpose: The Biplane Simpson (BPS) remains the recommended 2-dimensional method to assess left ventricular ejection fraction (LVEF). However, it has known limitations that may be overcome with 3D real-time triplane (RTTP), for instance, obtaining all apical views simultaneously at the same …

AIMS: The concept of proportionate/disproportionate functional mitral regurgitation (FMR) has been limited by the lack of a simple way to assess it and by the paucity of data showing its prognostic superiority. The aim of this study was to evaluate the prognostic …

Abstract Funding Acknowledgements Type of funding sources: None. Background A Unifying Concept for the Quantitative Assessment of Secondary Mitral Regurgitation (SMR) was recently proposed in order to provide a solution for the ongoing guideline controversy. However, these data were derived from a …
