A 27-year-old man with bacterial endocarditis of the mitral valve and embolic episodes was bound to have a large right coronary artery fistula communicating with the left ventricle, immediately inferior to the posterior mitral annulus. The perforation of the posterior leaflet and coronary arteriovenous fistula was identified using two-dimensional Doppler echocardiography. The diagnosis was confirmed by coronary angiography, and the patient underwent a successful operation.
The presence of severe pulmonary arterial hypertension (PAH) in patients with atrial septal defect (ASD) is still thought to preclude shunt closure, although there are several reports of good clinical outcomes after vasodilator therapy. We report the case of a young woman with ASD and severe PAH who was able to successfully undergo percutaneous shunt closure following 1 year use of the oral endothelin receptor antagonist, bosentan.
Abciximab has a key role in the treatment of patients with acute coronary syndromes undergoing percutaneous coronary intervention; however, an increased risk of bleeding complications is well recognized. We report a case of serious pulmonary hemorrhage after use of abciximab therapy. A definitive indication and treatment guideline should be available to minimize serious bleeding complications. Additionally, respiratory symptoms should be monitored closely for early detection of serious pulmonary hemorrhage in patients receiving abciximab therapy during percutaneous coronary intervention.
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.
