Correlation of Right Atrial Strain With Pulmonary Hypertension, Right Ventricular Function And Outcome In Pediatric Patients

Correlation of Right Atrial Strain With Pulmonary Hypertension, Right Ventricular Function And Outcome In Pediatric Patients

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.

Inclusion Criteria:

• Undergoing elective cardiac surgery for congenital heart disease with left to right shunt
• Prior evidence of pulmonary arterial hypertension on preoperative echocardiography.

Exclusion Criteria:

• Neonates
• Children with history of previous cardiac surgery,
• Hemodynamic instability
• Non-sinus rhythm
