An 86-year-old nondiabetic woman with an episode of transient ischemic attack two days earlier was referred to our hospital. She had a history of neurogenic bladder and chronic atrial fibrillation and had been anuric for two days. Bubbles were detected by echocardiography in the right atrium, right ventricle, and inferior vena cava. Computed tomography revealed gas accumulation in the wall and lumen of the bladder. She recovered after urinary drainage and antibiotic therapy, and bubbles were no longer detected. It was suspected that bacterial injury of the bladder wall and high intravesical pressure led gas to enter the venous system.

Activation recovery intervals obtained from unipolar electrograms provide an accurate assessment of changes in action potential duration throughout the ischemic zone during acute no-flow ischemia, provided the characteristics of the electrograms meet specific predetermined criteria.

A74-year-old manwas referred to us for evaluation of a tumor in the right atrium (RA). Transesophageal echocardiography (TEE) showed an unmovable 50x60 mm mass in the RA. Based on histological findings of subcutaneous tumors in the right abdominal wall, he was diagnosed as malignant lymphoma(ML), and treated with a THP-COPregimen. Upon completion of first THO-COP therapy, TEEshowed marked regression of the mass and division into 3 masses, one of which showed marked floating movementwith a small stalk. To prevent the risk of embolic events, surgical resection was performed.Resected tumors were necrotic tissues. Serial imaging of cardiac tumor and surgical resection is desirable to decrease the possibility of embolic complication. (Internal Medicine 42: 336-339, 2003)
