The acute hemodynamic effects of pericardial closure were studied in 30 patients with normal left ventricular function, who were undergoing coronary artery bypass surgery. Closure of the pericardium resulted in decreases in arterial blood pressure ( P < 0.01), cardiac index ( P < 0.001), mean right atrial ( P < 0.001), mean pulmonary artery ( P < 0.001) and pulmonary capillary wedge pressure ( P < 0.001). The observed hemodynamic changes are probably caused by a change in the ventricular pressure–volume relationships.
