Longitudinal strain quantitates regional right ventricular contractile function.
The assessment of contractile function of the right ventricle (RV) is an important clinical issue, but this remains difficult because of its complex anatomy and structure. We thought to investigate whether new Doppler-derived myocardial deformation indexes may quantify regional contractile RV function during varying loading conditions. In nine pigs, ultrasonic crystals were inserted longitudina...
متن کاملChanges in Left Ventricular Global and Regional Longitudinal Strain During Right Ventricular Pacing
BACKGROUND Our study aimed to demonstrate the short-term impacts of right ventricular apical pacing (RVAP) and right ventricular septal pacing (RVSP) on left ventricular (LV) regional longitudinal strain (RLS) and global longitudinal strain (GLS) in patients with preserved ejection fraction (EF). LV strain and functions may be altered by RVAP. RVSP might be a better alternative. The detrimental...
متن کاملPrognostic value of right ventricular myocardial performance index in patients undergoing coronary artery bypass surgery
Abstract Background: Right ventricular myocardial performance index (RVMPI) is a Doppler–derived parameter of non-geometrical ventricular function that measures both systolic and diastolic functions of the right ventricle. The aim of this study is to compare prognostic value of RVMPI with global RV function in patients undergoing Coronary Artery Bypass Graft (CABG). Methods: In a longitudinal ...
متن کاملAssessment of right ventricular function.
PURPOSE OF REVIEW To emphasize the importance and clinical implications of right ventricular function assessment in many situations encountered by intensivists and to explain in practical terms how to perform such an assessment at the bedside. RECENT FINDINGS Assessment of right ventricular function requires a full understanding of the physiology of the right ventricle. The right ventricle, u...
متن کاملTwo-dimensional strain to assess regional left and right ventricular longitudinal function in 100 normal foetuses.
AIMS Previous reports have demonstrated that myocardial velocities are not sufficiently sensitive in foetal heart studies. Strain (S) imaging is a new non-invasive ultrasonic technique able to quantify regional myocardial deformation properties. Strain imaging has a superior sensitivity than myocardial velocity for non-invasive assessment of ventricular function. However, Doppler-derived strain...
