Complete atrioventricular block due to a hydatid cyst located in the interventricular septum: A case report

Abstract

We report a case of complete atrioventricular block and tricuspid valve insufficiency due to a cardiac hydatid cyst located in the interventricular septum that occurred in a 19-year-old male patient. Surgery was carried out with the help of cardiopulmonary bypass. The cyst was excised, and the interventricular septum was closed with an autologous pericardial patch treated with glutaraldehyde. The tricuspid valve insufficiency was repaired with annuloplasty. A dual-chamber epicardial pacemaker was implanted. The postoperative course was uneventful, and the patient was doing well 6 months after discharge. This is the first report of a cardiac hydatidosis case for which the repair of the interventicular septum, tricuspid annulopasty, and permanent pacemaker implantation were performed during the same operation.
