Lesion length is a major predictor of adverse outcomes after percutaneous coronary intervention. Long lesions often require multiple stents with variable overlap, which increases the probability of geographical miss and the incidence of mechanical complications, such as side-branch occlusion, restenosis, and stent thrombosis. These pitfalls may be avoided by use of an ultra-long device.

We retrospectively assessed the performance of the 48-mm Xience Xpedition everolimus-eluting stent (EES) at our institution.

A total of 123 patients (mean age: 60.94 years, n = 93 [76%] male) with 129 lesions were identified. Lesions (n = 69, 53.5%) were located in the left anterior descending artery, the right coronary artery (n = 47, 36.4%), and the circumflex artery (n = 8, 6.2%); 83 lesions involved a major side branch. The majority were treated with a provisional single-stent strategy. Other characteristics included significant tortuosity in 15 lesions (11.6%) and moderate-to-heavy calcification in 46 lesions (35.7%). In all cases, balloon pre-dilatation was performed before stent insertion. Successful delivery and deployment of the 48-mm EES device was achieved in 100% of the patients. The mean number of stents per lesion was 1.4, while the mean total stent length was 58 ± 17.3 mm and mean stent diameter, 3.00 ± 0.67 mm. The procedural success rate was 99.2%. The 30-day major cardiac adverse event (MACE) rate was 0.8%, while the 12-month MACE was 3.3%.

The Xience 48-mm EES device appears to be safe and efficacious with a low clinical event rate at the 12-month follow-up. Where feasible, this would support the use of the ultra-long 48-mm platform in lieu of multiple overlapping shorter devices.
