RV dyssynchrony in PAH as evidenced by slice to slice minimum volume timing
نویسندگان
چکیده
Background Pulmonary hypertension has been associated with right ventricular (RV) dyssynchrony. In patients with left side heart failure, treating left ventricular dyssynchrony has been shown to improve patient outcome. Previous studies have demonstrated that RV dyssynchrony was associated with RV dilation, interventricular septum diastolic flatterning and eccentric hypertrophy. We propose simple parameters from cine MRI that can potentially help quantify the complex movements without using special sequences or algorithms.

RV Dyssynchrony by Speckle Tracking Strain in Pulmonary Arterial Hypertension: Will This Outcome Variable Take Root?
SEE PAGE 642 T he pressure overload of pulmonary arterial hypertension (PAH) predisposes the right ventricle (RV) to hypertrophy, dilation, and reduced pump function. Alterations in RV functional indexes such as tricuspid annular plane excursion, fractional area change, and tissue Doppler myocardial velocity have been shown to have prognostic significance in PAH (1). With the advent of strain a...
متن کاملWhy septal motion is a marker of right ventricular failure in pulmonary arterial hypertension: mechanistic analysis using a computer model.
Rapid leftward septal motion (RLSM) during early left ventricular (LV) diastole is observed in patients with pulmonary arterial hypertension (PAH). RLSM exacerbates right ventricular (RV) systolic dysfunction and impairs LV filling. Increased RV wall tension caused by increased RV afterload has been suggested to cause interventricular relaxation dyssynchrony and RLSM in PAH. Simulations using t...
متن کاملExternal radiotherapy of intact breast: A comparison between 2D (single CT- slice) and 3D (full CT-slices) plans
Background: Tangential irradiation of intact breast is one of the most common procedures performed in any radiotherapy center. This method is performed by using 2D and 3D treatment planning. The aim of this study was to compare 2D with 3D plans in breast conserving radiotherapy. Homogeneity of isodose, and lung received dose were compared. Materials and Methods: Twenty patients with br...

متن کاملThe associations between tricuspid annular plane systolic excursion (TAPSE), ventricular dyssynchrony, and ventricular interaction in heart failure patients.
AIMS Ventricular interactions may be mediated by loading conditions and biventricular timing and coordination. We sought to understand the relationships between right (RV) and left ventricular (LV) function and dyssynchrony, examine the RV correlates of LV dyssynchrony, and determine whether improved loading conditions affect inter-ventricular interaction. METHODS AND RESULTS In 25 heart fail...
