Acquired coronary artery aneurysm following treatment with bioresorbable vascular scaffolds

A 41-year-old female underwent deployment of two bioresorbable vascular scaffolds (BVS) (3.5×28 mm, 3.5×18 mm) (Abbott Vascular, Santa Clara, CA, USA) to a long segment of disease in the right coronary artery (RCA) as a staged intervention to bystander disease following a myocardial infarction. Due to a significant waist post deployment, post-dilation with 3.5×20 mm Pantera (Biotronik, Berlin, Germany) and 3.5×12 mm Quantum Apex™ (Boston Scientific, Marlborough, MA, USA) non-compliant balloons to 18 atm was required.

She re-presented with angina 21 months later. Angiography revealed a significant ostial RCA stenosis, with a localised coronary artery aneurysm within the scaffolded segment (Panel A). Pressure ...
