Fig 1 Treatment of type I UCSS by constructing internal tunnel: A.
Preoperative TTE showed that LSVC drained into LA and CS was totally
unroofed, associated with single atrium. B. Postoperative TEE showed
drainage of LSVC to CS by establishing intracardiac tunnel. C. During
the operation, a straight drainage tube was inserted into LSVC directly
and the internal tunnel(arrow) was anastomosed along the tube.
