Akın A, Alehan D, Aykan HH, Özkutlu S, Özer S, Karagöz T. Evaluation of Tissue Doppler Echocardiographic Imaging findings in children with pulmonary hypertension. Turk J Pediatr 2017; 59: 244-253. Tissue Doppler Imaging has become an important prognostic marker that can be used in follow-up and determination of the prognosis in pulmonary hypertension patients. We compared the Tissue Doppler ima...
متن کاملRV contractility and exercise-induced pulmonary hypertension in chronic mountain sickness: a stress echocardiographic and tissue Doppler imaging study.
OBJECTIVES The aim of this study was to evaluate right ventricular (RV) and left ventricular function and pulmonary circulation in chronic mountain sickness (CMS) patients with rest and stress echocardiography compared with healthy high-altitude (HA) dwellers. BACKGROUND CMS or Monge's disease is defined by excessive erythrocytosis (hemoglobin >21 g/dl in males, 19 g/dl in females) and severe...
متن کاملAccuracy of Doppler echocardiographic estimates of pulmonary artery pressures in a canine model of pulmonary hypertension.
OBJECTIVES To compare noninvasive estimates of pulmonary artery pressure (PAP) obtained via echocardiography (ECHO) to invasive measurements of PAP obtained during right heart catheterization (RHC) across a range of PAP. To examine the accuracy of estimating right atrial pressure via ECHO (RAPECHO) compared to RAP measured by RHC (RAPRHC), and determine if adding RAPECHO improves the accuracy o...
متن کاملAccuracy of Doppler-Echocardiographic Mean Pulmonary Artery Pressure for Diagnosis of Pulmonary Hypertension
BACKGROUND The validity of Doppler echocardiographic (DE) measurement of systolic pulmonary artery pressure (sPAP) has been questioned. Recent studies suggest that mean pulmonary artery pressure (mPAP) might reflect more accurately the invasive pressures. METHODOLOGY/PRINCIPAL FINDINGS 241 patients were prospectively studied to evaluate the diagnostic accuracy of mPAP for the diagnosis of PH....
