Key Points

This research aims to evaluate the effectiveness of biodegradable polymer drug-eluting stents in treating coronary artery aneurysms using intravascular imaging techniques.
Conducted coronary angiography (CAG) before and after percutaneous coronary intervention (PCI).
Utilized intravascular ultrasound (IVUS) to assess stent apposition and aneurysm resolution.
Monitored healing using optical coherence tomography (OCT) over one year.
CAG demonstrated resolution of the aneurysm one month post-PCI.
IVUS confirmed proper stent apposition and absence of restenosis after one year.
CAS revealed complete healing and absence of thrombi at follow-up.

Abstract

Figure.Imaging findings.A, B: CAG of the coronary artery was performed before (A) and after (B) PCI.C: Post-PCI.IVUS showed stent malapposition.D-F: At one month.CAG showed aneurysm resolution (D); IVUS confirmed apposition (E); and CAS showed red thrombi and uncovered struts (F).G-J: At one year.CAG showed persistent resolution (G); IVUS showed good apposition without restenosis (H); CAS showed complete healing (I); and OCT showed uniform neointimal
