| A 49-year-old man was admitted to
another hospital because of exertional dyspnea. He had run an
entire 20-km race 33 days before admission. Echocardiograms,
MRI and CT scans, and cineangiograms showed a right ventricular
tumor arising from the tricuspid valve, which occupied the area
from the right ventricular outflow tract (RVOT) to the pulmonary
trunk and extended to the bilateral pulmonary arteries. MRI scans
suggested that the tumor had not invaded the normal cardiac structure.
The patient was transferred to our hospital for surgery. An operation
was performed on the same day, since the tumor could have caused
pulmonary embolisms. Under cardiopulmonary bypass, a right atriotomy,
pulmonary arteriotomy and incision in the RVOT were made. The
tumor had adhered to the chordae of the tricuspid valve, myocardium
of the RVOT, and pulmonary valve. It was completely resected
macroscopically. The postoperative course was uneventful and
the patient was discharged on the 18th postoperative day. The
size of the tumor was 2.0×2.0×10.0cm and the histological diagnosis
was angiosarcoma. The patient died 4 months after the operation
due to brain metastasis and local recurrence. This appeared to
be a case of rapidly progressive cardiac angiosarcoma with an
unusual noninvasive growth pattern. Jpn. J. Cardiovasc. Surg.
