Clinical Report: IVUS-Guided PCI for Coronary Ostial Lesions Due to Syphilis

Overview

This study evaluates the feasibility and safety of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) for syphilitic coronary artery ostial lesions (SCAOL).

Background

Cardiovascular syphilis can lead to significant coronary ostial stenosis, posing a risk for acute myocardial infarction or sudden cardiac death. Traditional revascularization methods like CABG may not be suitable for all patients, necessitating further exploration of PCI as an alternative.

Data Highlights

Key Findings

• IVUS-guided PCI was technically feasible in patients with SCAOL.
• Pre-procedural IVUS revealed concentric fibrous hyperplasia and significant negative remodeling.
• All patients received second-generation drug-eluting stents (DES) successfully.
• Six patients remained free of major adverse cardiovascular events over a median follow-up of 4 years.
• One patient developed NSTEMI due to severe in-stent restenosis after receiving a flush-alignment stent.

Clinical Implications

The study emphasizes the need for further exploration of stent positioning strategies in patients with SCAOL.

Conclusion

IVUS-guided PCI for SCAOL requires further investigation to confirm optimal stent positioning strategies and their impact on restenosis.
