Large coronary pseudoaneurysm with pulmonary artery fistula, six months after left main trunk stenting with paclitaxel-eluting stent.

There are no reported cases of a pseudoaneurysm leading to a fistula into the pulmonary artery after percutaneous coronary intervention. We describe a patient who developed a late pseudoaneurysm after left main trunk (LMT) stenting with paclitaxel-eluting stent, discovered during coronary angiography. Transesophageal echocardiography and contrast-enhanced computed tomographic scan revealed a pericardial effusion, a large pseudoaneurysm communicating with LMT and a fistula into the pulmonary artery. The recommended therapy was surgery.
