Inflammatory Pericardial Pseudocyst Secondary to Atrial Myocardial Perforation: A Rare Complication following Transvenous Pacemaker Implantation

Abstract EN

Pericardial cyst is an uncommon clinical-pathological entity, most often a congenital condition.

We describe a case of an acquired iatrogenic pericardial pseudocyst following permanent pacemaker implantation secondary to atrial myocardial perforation.

Diagnosis was achieved by a plain chest film, echocardiography, and computed tomography and confirmed intraoperatively.

The pseudocyst was resected via a midline sternotomy approach.

The patient recovered uneventfully.

In a follow-up of 18 months, the patient is doing well.
