Primary Outcome Measures:
  • All cause-death [ Time Frame: Within 30 days after surgery or during postoperative hospitalization ]

Secondary Outcome Measures:
  • gastrointestinal or hepatobiliary complications requiring intervention [ Time Frame: Within 30 days after surgery or during postoperative hospitalization ]

Estimated Enrollment: 1000
Study Start Date: June 2012
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Detailed Description:
Patients receiving elective cardiac or thoracic aorta surgery will be monitored for the development of postoperative hyperbilirubinemia. Collection of data will include patient baseline demographic characteristics, laboratory and echocardiographic findings, procedural factors of the surgery, and early postoperative variables. Serial postoperative liver function testings will be done during the hospitalization. Postoperative hyperbilirubinemia is defined as serum bilirubin level of 3mg/dL.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients undergoing elective major cardiac or thoracic aorta surgery

Inclusion Criteria:

Patients aged over 18 years who are scheduled to undergo elective major cardiac or thoracic aorta surgery. Major cardiac surgery includes coronary artery bypass grafting, pericardiectomy and corrections of cardiac diseases using cardiopulmonary bypassing (valve surgery, tumor excision, arrhythmia surgery, heart transplantation, ventricular reconstruction, pulmonary thromboembolectomy, and atrial or ventricular septal defects closure).

Exclusion Criteria:

  1. univentricular or one-and-half ventricle repairs
  2. presence of known liver cirrhosis or hepatic cancer
  3. history of liver transplantation
  4. Genetic diseases that affects bilirubin metabolism (i.e. Gilbert syndrome)
  5. preoperative bilirubin level of 3mg/dL or more.
