3D Echocardiography of the LV and RV
The evaluation of the global and regional left ventricular (LV) function is an essential part of a routine perioperative TEE-examination. To date, the assessment of the LV ejection fraction (EF) is mainly performed by “eye-balling”, which relies on the echocardiographer’s experience and ability to visually integrate spatial information. Further limitations of 2D-TEE assessment of the LV EF are ...
متن کامل3D Morphological Changes in LV and RV During LVAD Ramp Studies.
OBJECTIVES The purpose of this study was to investigate the differential impact of the 2 most commonly available left ventricular assist device (LVAD) types on the right ventricle (RV) and left ventricle (LV) using 3-dimensional (3D) echocardiography-based analysis of ventricular morphology. BACKGROUND LVADs have emerged as common therapy for advanced heart failure. Recent data suggest that t...
متن کاملCMR 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 کاملPulmonary Hypertension and RV Failure
Introduction: Pulmonary hypertension (PH) and the associated RV dysfunction is increasingly being encountered in the perioperative period. Managing these patients is challenging, but a thorough understanding of the pathophysiology of PH and the associated RV dysfunction allows the practioner to anticipate, prevent and successfully manage many of the perioperative risks. The normal systolic, dia...
متن کاملPartial LVAD restores ventricular outputs and normalizes LV but not RV stress distributions in the acutely failing heart in silico
PURPOSE Heart failure is a worldwide epidemic that is unlikely to change as the population ages and life expectancy increases. We sought to detail significant recent improvements to the Dassault Systèmes Living Heart Model (LHM) and use the LHM to compute left ventricular (LV) and right ventricular (RV) myofiber stress distributions under the following 4 conditions: (1) normal cardiac function;...
