Evaluation 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 کاملRight 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 کاملRIGHT ATRIAL MYXOMA
A case of right atrial myxoma in a 5 year old male is presented. The Patient was admitted in the pediatric department with systemic manifestations. Myxoma was incidentally diagnosed.
متن کاملEvaluation of Advanced Echocardiographic Parameters of Right Ventricular in Patients with Pulmonary Hypertension
Background and Objective: Pulmonary hypertension is an increase in blood pressure of the pulmonary artery which leads to right ventricular dysfunction. Therefore, the present study aimed to compare echocardiographic parameters in the study of right ventricular failure in patients with pulmonary hypertension. Materials and Methods: In the present descriptive cross-sectional study, data were col...
