Coronary bypass in a patient with hemophilia B, or Christmas disease. Case report.

A 40-year-old patient with moderate factor IX deficiency (Christmas disease) underwent quadruple saphenous vein coronary bypass grafts for angina and severe coronary atherosclerosis involving the left and right main, left anterior descending, and circumflex coronary arteries. Excessive bleeding was prevented by infusion of factor IX concentrates during and after the operation. The surgical procedure and total body perfusion were carried out in the same manner as in patients without a hemorrhagic disorder. The patient was discharged after 13 days of hospitalization. He is doing well at the time of this publication and has returned to work.

Bilateral atrial myxomas. Echocardiographic considerations.

In this report we describe a patient with bilateral atrial myxomas, which were diagnosed preoperatively by echocardiography and angiography, and successfully removed. The excised tumor mass consisted of mobile right and left atrial myxomas connected by a common stalk which passed through the atrial septum, collectively resembling the shape of a dumbbell. Preoperative echocardiographic and angiographic observations were instrumental in planning the surgical approach, and correlated well with intraoperative findings and with the anatomic configuration of the intact pathologic specimen. Diagnostic aspects of echocardiography are emphasized as they relate to both isolated and bilaterally-occurring atrial myxomas.
