ABSTRACT
Various complications may occur during percutaneous coronary interventions (PCI) (Table 38.1). These may be related to the devices used during the procedure (e.g., coronary perforation, stent loss, or thrombosis) or to the intervention itself (e.g., abrupt vessel closure, distal embolization, side branch occlusion). The circulatory system may also be affected in case of aortic dissection or vascular or atheroembolic events. In addition, access site complications may occur. Finally, PCI may be complicated by systemic events in relation to adjunctive therapies and other aspects of the procedure (e.g., contrast nephropathy, hemorrhage, allergic reactions). These complications may result in adverse events such as myocardial infarction, renal failure, stroke, or death.
