Key result
Staged PK Papyrus covered stenting successfully excludes a thrombosed coronary aneurysm after acute MI.
Why the study?
Coronary artery aneurysm is an uncommon condition that can cause dangerous complications such as myocardial infarction, and percutaneous intervention using covered stents has recently emerged as an alternative to surgical treatment when the anatomy is suitable.
Case Report (n=1)
No
This case report demonstrates that initial aspiration thrombectomy and anticoagulation followed by staged PK Papyrus covered stent placement is a safe and effective short-term strategy for managing acute myocardial infarction caused by thrombosis in a suitable coronary artery aneurysm.

May support covered stent exclusion after thrombectomy for aneurysm-related MI; leaves open need for larger studies on durability and generalizability.
Coronary artery aneurysm is an uncommon disease, Aneurysm when the diameter of dilatation increases more than 50% of the diameter of reference artery (normal segment). The cause can be artherosclerosis, congenital, inflammatory, connective tissue disease or Kawasaki disease. Most aneurysms detect incidentally or when complicacated. The coronary aneurysm can cause dangerous complications such as myocardial infartion, arrhythmias, compression of surrounding structures, rupture or sudden death. Medical treatment only for small, asymptomatic. Surgical treatment is basic but recently percutaneous intervention emerges by using covered stenting which is increasingly popular and has many advantages if anatomy of aneurysm is suitable. Clinical case: The clinical case we encountered was admitted to the hospital due to chest pain, low blood pressure and was diagnosed with posterior inferior myocardial infarction. Percutaneous coronary angiography showed posterior lateral branch (PLV) occlusion of the right coronary artery on the background of a coronary artery aneurysm. The patient was treated with coronary revascularization thrombectomy and successfully treated the aneurysm with covered stent placement at Hanoi Heart Hospital.

Nguyen et al. (2026) conducted a case report in Acute posterior inferior myocardial infarction due to thrombosis in a right coronary artery aneurysm (n=1). Coronary thrombectomy followed by PK Papyrus covered stent placement was evaluated on Angiographic aneurysm exclusion, restoration of coronary blood flow (TIMI 3), and clinical symptom resolution. Coronary thrombectomy and staged PK Papyrus (3.0x18 mm) covered stent placement achieved TIMI 3 flow and complete exclusion of a 7x6 mm right coronary artery aneurysm in a 37-year-old female with MI.
