Brief summary
The purpose of this study is to analyze the changes in right ventricular strain before and after milrinone administration in order to find out whether milrinone improves RV systolic performance in patients undergoing cardiac surgery.
Interventions
giving intravenous milrinone: 50 mcg/kg loading dose by IV push over 10 minutes, then 0.375-0.75 mcg/kg/ min infusion
