Recurrent positional unilateral pulmonary edema following CABG: an uncommon case report

We reported a case of pericardial agenesis discovered at the age of 60 during coronary artery bypass grafting surgery. However, this anomaly was not treated during the initial surgery. During the post-operatory period, the patient developed recurrent unilateral right pulmonary edema whenever assuming a semi-upright position. We hypothesized that the positional hemodynamic alterations in this patient were related to this rare congenital anomaly. The patient underwent reoperation, 48 hours later, with synthetic pericardial reconstruction and experienced an uneventful recovery during follow-up.
