Overview
Brief Summary
Observational study of patients undergoing open heart surgery. During the procedure video clips of right heart are stored and compared to trans-oesophageal ultrasound recordings and ECG recordings.
Detailed Description
Observational study of patients undergoing open heart surgery. During the procedure video clips of right heart are stored and compared to trans-oesophageal ultrasound recordings and ECG recordings. Right heart volume status and function is controlled and induced with theophylline and ventilator regulated positive end-expiratory pressure recordings.
