No results posted yet for this study

Summary

This observational study aims to assess correlation of right atrial strain measured by two-dimensional speckle tracking echocardiography with intraoperatively measured pulmonary artery pressures, other indices of right ventricular function and short term postoperative outcome.

Conditions

  • Pulmonary Hypertension

Interventions

DIAGNOSTIC_TEST

Transthoracic and transesophageal echocardiography

After induction of anaesthesia and stabilization of hemodynamics, transthoracic echocardiography will be done on a GE Vivid e9 workstation (GE Vingmed, Horton, Norway) with MS5 transthoracic probe with synchronized ECG. From TTE the following views and measurements will be acquired : * Apical four chamber (A4C) view * Apical two chamber view (A2C) view * Right ventricle (RV) focused A4C view * Right ventricular systolic pressure (RVSP) * Pulmonary arterial acceleration time (PAAT), * Tricuspid annular plane systolic excursion (TAPSE), * Tricuspid annular plane systolic velocity (s'), * Right ventricular fractional area change (RV FAC) * RV free wall strain, * RV myocardial performance index (MPI), * RV isovolumic relaxation time (IVRT), * RV isovolumic acceleration time (IVA) Invasive PA pressure measurement will be done after surgical exposure with a fine needle and a zeroed transducer by the Surgeon.
