CASE REPORT
A 47-year-old female with a past medical history notable for complete
d-TGA and an extensive interventional history (Table 1 )
presented with SVC syndrome. An echocardiogram revealed a high-grade
stenosis of the SVC baffle from the SVC to the LA, with a mean gradient
of 5 mmHg and remaining luminal area of approximately 1 mm. A
nonfunctional permanent pacemaker lead passing through the baffle and
located in the LA was contributing to the obstruction and the patient
was scheduled for extraction of the LA lead and balloon angioplasty and
stenting of the SVC baffle.
