AI Article Synopsis
- This study compared target vessel failure (TVF) rates 3 years after drug-eluting stent (DES) implantation using either intravascular ultrasound (IVUS) guidance or angiographic guidance.
- Results showed that IVUS guidance led to lower TVF rates (6.6%) compared to angiography (10.7%), primarily due to fewer clinically driven target vessel revascularizations.
- Additionally, the incidence of stent thrombosis was also significantly lower in the IVUS group (0.1%) versus the angiography group (1.1%).
Article Abstract
Objectives: The aim of this study was to explore the difference in target vessel failure (TVF) 3 years after intravascular ultrasound (IVUS) guidance versus angiographic guidance among all comers undergoing second-generation drug-eluting stent (DES) implantation.
Background: The multicenter randomized ULTIMATE (Intravascular Ultrasound Guided Drug Eluting Stents Implantation in "All-Comers" Coronary Lesions) trial showed a lower incidence of 1-year TVF after IVUS-guided DES implantation among all comers compared with angiographic guidance. However, the 3-year clinical outcomes of the ULTIMATE trial remain unknown.
Methods: A total of 1,448 all comers undergoing DES implantation who were randomly assigned to either IVUS guidance or angiographic guidance in the ULTIMATE trial were followed for 3 years. The primary endpoint was the risk for TVF at 3 years. The safety endpoint was definite or probable stent thrombosis (ST).
Results: At 3 years, TVF occurred in 47 patients (6.6%) in the IVUS-guided group and in 76 patients (10.7%) in the angiography-guided group (p = 0.01), driven mainly by the decrease in clinically driven target vessel revascularization (4.5% vs. 6.9%; p = 0.05). The rate of definite or probable ST was 0.1% in the IVUS-guided group and 1.1% in the angiography-guided group (p = 0.02). Notably, the IVUS-defined optimal procedure was associated with a significant reduction in 3-year TVF relative to that with the suboptimal procedure.
Conclusions: IVUS-guided DES implantation was associated with significantly lower rates of TVF and ST during 3-year follow-up among all comers, particularly those who underwent the IVUS-defined optimal procedure compared with those with angiographic guidance.

Objective: This study aimed to compare the efficacy and safety of intravascular ultrasound (IVUS)-guided coronary intravascular lithotripsy and rotational atherectomy in treating severe coronary artery calcification.
Methods: A retrospective analysis of 60 patients who underwent percutaneous coronary intervention at the General Hospital of Ningxia Medical University from October 2022 to August 2023 was conducted. The patients were divided into two groups: 30 received IVUS-guided coronary intravascular lithotripsy and 30 underwent IVUS-guided rotational atherectomy.

Quantifying the mechanical properties of coronary arterial walls could provide meaningful information for the diagnosis, management, and treatment of coronary artery diseases. Since patient-specific coronary samples are not available for patients requiring continuous monitoring, direct experimental testing of vessel material properties becomes impossible. Current coronary models typically use material parameters from available literature, leading to significant mechanical stress/strain calculation errors.
