Objectives: The present study aimed to evaluate long-term cardiac survival benefit for intravascular ultrasound (IVUS)- versus angiography-guided long drug-eluting stent (DES) implantation.

Background: Although the long-term benefit of IVUS guidance for DES implantation has been reported from recent randomized trials, this benefit was primarily driven by the reduction in repeat revascularization. Thus, it remains uncertain whether IVUS guidance improved survival during long-term follow-up.

Methods: We pooled the data of 2 randomized trials (IVUS-XPL [Impact of Intravascular Ultrasound Guidance on the Outcomes of Xience Prime Stents in Long Lesions] and ULTIMATE [Intravascular Ultrasound Guided Drug Eluting Stents Implantation in All-Comers Coronary Lesions]) and compared IVUS guidance versus angiography guidance in 2,577 patients with long lesions treated with an implanted stent length ≥28 mm. The primary end point was cardiac death at 3 years.

Results: A 3-year clinical follow-up was completed in 96%. The primary end point of cardiac death occurred in 12 patients (1.0%) in the IVUS-guided group vs 28 patients (2.2%) in the angiography-guided group (HR: 0.43; 95% CI: 0.22-0.84; P = 0.011). In addition, target lesion-related myocardial infarction occurred in 3 patients (0.2%) in the IVUS-guided group and in 9 patients (0.7%) in the angiography-guided group (HR: 0.33; 95% CI: 0.09-1.22; P = 0.081), stent thrombosis developed in 3 patients (0.2%) in the IVUS-guided group and 9 patients (0.7%) in the angiography-guided group (HR: 0.33; 95% CI: 0.09-1.23; P = 0.082), and ischemia-driven target lesion revascularization was observed in 47 patients (3.8%) in the IVUS-guided group and 80 patients (6.5%) in the angiography-guided group (HR: 0.57; 95% CI: 0.40-0.82; P = 0.002).

Conclusions: In this post hoc pooled patient-level analysis, the use of IVUS-guided long DES implantation compared with angiography-guided stent implantation improved long-term patient cardiac survival.
