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 paclitaxeleluting 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
