Giant left atrium is a condition characterized by an extreme enlargement of the left atrium with a diameter more than 80 mm and it is usually associated with long standing rheumatic mitral valve disease. We present a case of giant left atrium in a 47-year-old female patient who had a history of rheumatic heart disease, severe mitral disease, permanent atrial fibrillation and causing the compression of adjacent intra-thoracic structures. The patient underwent a successful mitral valve replacement with reduction of the enlarged sized left atrium with good outcomes.
Giant coronary artery aneurysms that occur in 0.5 to 1% of patients with Kawasaki disease can be fatal if associated with thrombosis. Some patients may show persistent inflammation and fever despite treatment with repeated doses of intravenous immunoglobulin (IVIG), steroids, and aspirin. This report describes an infant boy with resistant Kawasaki disease who presented with extensive coronary artery involvement and coronary thrombosis. His inflammation was not controlled with multiple doses of IVIG, parenteral and oral steroids, or high-dose aspirin, and he finally needed infliximab, a monoclonal antibody against tumor necrosis factor alpha.
Scimitar syndrome or Felsons veno-lobar syndrome is a very rare congenital disease characterized by a combination of cardiopulmonary abnormalities, including partial right-sided pulmonary venous drainage to the inferior vena cava, the inferior cavo-atrial junction, or low on the right atrium. We report the case of a 53-year-old female patient who presented with recent gradually worsening dyspnea. The diagnosis was suspected on the chest x-ray and confirmed on Cardiac echography andComputed Tomography scan that showed a wide collector gathering the three right superior pulmonary veins that joins the lower part of the superior vena cava, thus joining the right atrium while the right inferior pulmonary vein is drained into the inferior vena cava. The patient was treated surgically by performing a derivation of the right superior pulmonary venous collector to the left atrium with a tricuspid annuloplasty with a good outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations 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.
