Right atrial ball-valve thrombus: a complication of central venous alimentation in an infant. Diagnosis and successful surgical management of a case

J Thorac Cardiovasc Surg. 1979 Oct;78(4):579-82.


The following is a case report of a 6-week-old premature infant in whom a ball-valve thrombus developed after prolonged central venous alimentation. Clinical presentation included facial edema, cyanotic episodes, and apnea. No murmur was present, but the diagnosis was suspected when a calcified right atrial mass became apparent on the plain chest film. The diagnosis was confirmed by echocardiography and then venous and cardiac angiography. The calcified thrombus was removed successfully from the right atrium by use of profound hypothermia with ether anesthesia and total circulatory arrest. Subsequently, the patient made an uneventful recovery and is healthy 3 years postoperatively.
