Potential goals for the dimensions of the pulmonary arteries and aorta with stenting after the Fontan operation.
The purpose of this study was to clarify desired stent sizes for stenotic lesions in the post-Fontan circulation. Using angiograms from 22 patients before and at late follow-up (> or = 15 years) after the Fontan operation, we measured the maximum diameters of the proximal pulmonary arteries (PA) and the descending aorta. ⋯ Despite somatic growth, the % N of all vessel diameters decreased significantly after the Fontan operation. In conclusion, smaller-sized stents should be acceptable for both the pulmonary artery and descending aorta in the Fontan circulation.

Immediate protamine administration and sheath removal following percutaneous coronary intervention: a prospective study of 429 patients.
We tested the approach of reversing anticoagulation following PCI and immediate sheath removal in 429 consecutive patients. On completion of the PCI, protamine was administered, and the vascular sheath was immediately removed. Stents were used in 364 patients (85%) and GP IIb/IIIa inhibitors were used in 52 patients (12%). ⋯ Prior to 48 hr, eight patients (1.9%) required emergency PCI or coronary bypass surgery. Follow-up at 30 days observed no deaths and only three target vessel revascularizations (0.7%). In conclusion, immediate reversal of anticoagulation and sheath removal after PCI is safe and feasible.
