Abstract

|
|
15 patients with constrictive pericarditis who underwent interphrenic pericardiectomy (group A) between January, 1981 and April, 1983 and 11 patients who underwent radidal pericardiectomy (group B) between May, 1983 and September, 1984 were compared to the clinical improvement and the results of pre-and postoperative cardiac cat eterization.
In the group of partial pericardiectomy the pericardium was removed anteriorly from the left phrenic nerve to the right phrenic nerve and in the group of radical pericardiectomy the pericardium was removed from almost entire surface of the heart including diaphragmatic surface and posterior wall of the left ventricle.
The following results were obtained.
1) Both group of the patients showed marked symptomatic improvement early after operation.
2) The central venous pressure was decreased significantly after operation in both group of the patients.
3) The right atrial mean pressure and pulmonary arterial mean pressure were decreased significantly after operation in both group of the patients and there was no significant difference in the amplitude of decrease between the two groups.
4) The right ventricular end-diastolic pressure and left ventricular end-diastolic pressure were decreased postoperatively in both group of the patients and the patients of the radical pericardectomy showed more decrease than the patients of interphrenic pericardiectomy, and right ventricular end-diastolic pressure and left ventricular enddiastolic pressure were normalized postoperatively in the group of radical pericardiectomy but the patients of interphrenic pericardiectomy showed abnormaly high pressure persistantly.
5) EF showed normal level pre-and postoperatively in both group of the patients.
