Abstract
Introduction: Pericardiectomy for constrictive pericarditis is a technical challenge because of dense adhesions to the epicardial surface of the heart. The procedure contains the possibility of unexpected bleeding or cardiac laceration. We present a novel device, to be used during the Waffle procedure, for releasing the constricted visceral pericardium.
Case Report: A retrospective review of three patients underwent the Waffle procedure using the vessel knife D 500. This knife is a specially designed vessel knife for coronary artery dissection. Intraoperative events, the amount of blood loss, and postoperative cardiac functions were examined. No major intraoperative complications were observed. The average amount of blood loss during the operation was 206 g. Postoperative echocardiography showed improvement in diastolic function in all three patients.
Conclusion: This device is safe and it is easy to learn how to use it. Moreover, the vessel knife can prevent injury to the myocardium and coronary artery underlying the thickened visceral pericardium.
