[Surgical management of constrictive pericarditis].

Cases of constrictive pericarditis per a institute is few for decrease of this disease. Therefore for surgical management of constrictive pericarditis, it has not been clear whether cardiopulmonary bypass during operation is necessary or not, and the reports of long term results are few. We gathered information by questionnaires from thirty-four institutes, which constitute Tokai Cardiovascular Surgeons Conference in Shizuoka, Aichi, Mie and Gifu Prefecture, for surgical management of constrictive pericarditis, and investigated its results. Etiology of constrictive pericarditis is idiopathic (49%), tuberculosis (29%) or post open heart surgery (10%). Hospital death included operative death is 14%, and postoperative liver complications was many next to heart complications. The cases, whose NYHA functional class at discharge did not improve compared with preoperative state, was 33%. At one year after operation two third of them improved in NYHA functional class, but the others did not improved.
