Pericardium closure after heart operations: a safety option?

Objectives: Primary pericardium closure may reduce the risk of cardiac injury during chest re opening, especially the right ventricle, aorta and coronary bypass grafts. Nevertheless, concern about adverse hemodynamic effects prevents most heart surgeons of closuring the pericardium.

Methods: We evaluated 48 patients undergoing open heart surgery consecutively which the pericardium was closed in 30 patients (group A) and 18 patients, as a control group (group B) in which the pericardium was left open.
