We found that RVRP occurs when patients have lower SP02(< 80%), heigher HCT value, transannular patch repair, longer CPB time (> 110 min), longer aortic cross clamping time(> 100 min), lower TAPSE, PASP and TAPSE/PASP ratio and presence of ventricular hypertrophy. This evidence concerns the gene CPB1 and cardiac hypertrophy.
