A case of left atrial compression secondary to angioedema.

Angioedema due to angiotensin-converting enzyme (ACE) inhibitors is an uncommon, but deadly adverse reaction with an overall incidence of 0.1%-0.2%. Rapid accumulation of interstitial fluid and vasodilation classically involves the mucus membranes of the mouth and face but has the ability to affect other areas. We describe a case of angioedema secondary to ACE inhibitor that affected the esophagus causing left atrial compression and hemodynamic compromise.
