Right Atrial Function in Pulmonary Arterial Hypertension.
BACKGROUND Elevated right atrial (RA) pressure is an established prognostic measure in pulmonary arterial hypertension (PAH). However, little is known about perturbations in RA function in PAH. METHODS AND RESULTS Reservoir (RA longitudinal strain [RA LS]), conduit (RA early LS rate), and active (RA late LS rate) phases were assessed by 2D speckle tracking in 65 patients with PAH, 6-minute wa...
متن کاملEvaluation of right atrial function using right atrial speckle tracking analysis in patients with pulmonary artery hypertension
BACKGROUND In patients with pulmonary artery hypertension (PAH), right ventricular pressure overload eventually causes right heart failure (RHF), leading to a poor prognosis. Right atrial (RA) overload and RA dysfunction occur in patients with PAH-complicated RHF. OBJECTIVES We evaluated RA function using right atrial longitudinal strain (RALS) by two-dimensional speckle tracking echocardiogr...
متن کاملPrognostic value of right ventricular mass, volume, and function in idiopathic pulmonary arterial hypertension.
AIMS This study investigated the relationship between right ventricular (RV) structure and function and survival in idiopathic pulmonary arterial hypertension (IPAH). METHODS AND RESULTS In 64 patients, cardiac magnetic resonance, right heart catheterization, and the six-minute walk test (6MWT) were performed at baseline and after 1-year follow-up. RV structure and function were analysed as p...
متن کاملRight atrial mechanics provide useful insight in pediatric pulmonary hypertension
Right atrial (RA) mechanics have been studied infrequently in children in the past due to technical constraints. With the advent of strain imaging, RA physiology can now be studied in greater detail. The principal aim of this study was to describe functional changes in right heart mechanics of children with idiopathic pulmonary arterial hypertension (PAH), by using new applications of RA strain...
متن کاملPulmonary hemodynamics and right ventricular function in hypertension.
Pulmonary and systemic hemodynamics in 16 hypertensive subjects (group I) with left ventricular (LV) hypertrophy (ECG and echo criteria) and in 17 hypertensive subjects with ECG signs of LV strain (group II), were compared with those in 14 normal individuals. An augmented pulmonary arteriolar resistance (PAR) in group I and to a larger extent in group II accounted for the pulmonary pressure ele...
