Summary:Percutaneous coronary intervention (PCI) is one of the most commonly performed cardiovascular interventions to treat significant coronary artery stenosis. Although a safe procedure, it carries the risk of complications like coronary artery perforation (CAP), bleeding, stroke, and acute kidney injury rarely resulting in death. The incidence of CAP is 0.84% of all PCI procedures and the incidence is increasing as cardiologists are accepting more and more challenging cases. CAP is caused by a guidewire (GW) or a vessel tear from balloon angioplasty, stenting, or rotational atherectomy. Though the majority of CAPs do not result in cardiac tamponade, some do lead to tamponade and death. The majority of distal wire perforations respond to prolonged balloon inflation, coils, glue, or fat embolization. Herein, we report a case of distal CAP in a 63-year-old woman occurring following left circumflex artery PCI caused by the exiting of coronary GW. The CAP was successfully sealed by the liquid embolization technique using ONYX. First described in 1990, Onyx is an elastic polymer composed of ethylene vinyl alcohol copolymer dissolved in dimethyl sulfoxide and mixed with micronized tantalum powder (Onyx). The Onyx is predominantly used by interventional radiologists while performing neurovascular and peripheral vascular interventions. There were only a few case reports of plugging of CAPs using Onyx. Our case highlights the safety and feasibility of closing distal CAPs using Onyx.
