Left atrial intramural hematoma after percutaneous coronary intervention.

We described a complication during percutaneous coronary intervention. A bleeding into the left atrial wall occurred after stenting of the right coronary artery. Echocardiography revealed the diagnosis of a left atrial intramural hematoma. Conservative treatment was performed. After 4 weeks the hematoma resolved completely. Left atrial intramural hematoma as a complication after percutaneous coronary intervention has not been reported in the literature yet.
