Trial Title: Factors Responsible for the Effectiveness of the Lund De-airing Technique

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: SUPPORTIVE_CARE
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Patients planned for aortic valve replacement with or without coronary vein bypass grafts~Exclusion Criteria:~* Significant chronic obstructive pulmonary disease and emphysema~* Previous history of thoracic or cardiac surgery~* Patients requiring internal mammary artery harvesting~* Unilateral or bilateral pulmonary adhesions to chest wall~* Previous radiation to the chest~Intraoperative Exclusion Criteria:~* Inability to obtain adequate bilateral Trans-cranial Echo-doppler signals~* Adherent pleurae~* Accidental opening of the pleurae

Study Arms:
- Open pleurae & conventional filling of heart (Type: EXPERIMENTAL): In this group both pleurae will be opened and the ventilator disconnected during cardiopulmonary bypass to ensure bilateral pulmonary collapse. However, after completion of the left heart procedure, the heart will be filled with blood actively from the heart-lung machine and manual de-airing performed in a conventional manner and de-airing monitored by intraoperative trans-esophageal echocardiography (TEE). After de-airing is complete and patient has been weaned off the cardiopulmonary bypass the residual air in the left heart will be quantitatively assessed by TEE and Trans-cranial Echo-Doppler (TCD) over a period of 10 minutes.
- Intact pleurae & staged filling of heart (Type: EXPERIMENTAL): In this group both pleurae will be left intact and the ventilator disconnected during cardiopulmonary bypass. After completion of the left heart procedure, the heart will be filled with blood actively from the heart-lung machine in a staged manner after adequate cardiac contraction has been established. De-airing will be obtained by active cardiac contraction and staged mechanical ventilation and de-airing monitored by intraoperative trans-esophageal echocardiography (TEE). After de-airing is deemed complete and patient has been weaned off the cardiopulmonary bypass (CPB) the residual air in the left heart will be quantitatively assessed by TEE and Trans-cranial Echo-Doppler (TCD) over a period of 10 minutes.

Based on this trial design, predict the completion outcome and termination type (if applicable).
