Result: Sixty seven patients included fifteen males and fifty two females, arithmetic mean age their was 45.5 ± 10.7. Mean arithmetic right ventricular stroke work index in T1, T2, T3 times were 10.51 ± 5.24, 6.4 ± 3.15 and 6 ± 3.12 (g*m/m²). Mean arithmetic cardiac output in T1, T2, T3 times were 2.4 ± 0.66, 4.37 ± 1.23 and 4.34 ± 1.05 (l/p). Conclusion: Right venticular and cardiac stroke work postoperative decreased preopeative with significant difference.
