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.
