Brief Summary:
Both left single lung ventilation by left double lumen tube and bilateral ventilation with selective blockage of right middle lower lobe by bronchial blocker can provide suitable surgical field for minimally invasive cardiac surgery. The current study was designed to compare the impact of these two different methods on oxygenation, degree of pulmonary collapse and postoperative complications.

Arm Intervention/treatment
Experimental: BB Device: bronchial blocker for BB group
Using bronchial blocker to block right middle lower lobe during surgery.

Experimental: DLT Device: double lumen tube for DLT group
Using double lumen tube to achieve single lung ventilation during surgery.

Primary Outcome Measures :
  1. oxygenation [ Time Frame: intraoperative ]
    record SpO2 and PaO2 during selective ventilation

Secondary Outcome Measures :
  1. degree of pulmonary collapse [ Time Frame: intraoperative ]
    surgeon score the degree of pulmonary collapse (1 for no pulmonary collapse and 5 for excellent pulmonary collapse)
