Why the study?
Does closing the pericardium with a biodegradable patch improve right ventricular function in patients undergoing coronary artery bypass surgery?
Does closing the pericardium with a biodegradable patch improve right ventricular function in patients undergoing coronary artery bypass surgery?
Closing the pericardium with a biodegradable patch during coronary artery bypass surgery does not prevent the postoperative changes in right heart function typically observed.
No takes yet. Share an insight, caveat, or question.
Patch closure does not prevent late septal or tricuspid annulus changes after CABG; hypothesis-generating and should not change practice pending RCTs.
Lindström et al. (2000) studied this question.
