Chronic total occlusion percutaneous coronary intervention complications: prevention and management

Abstract

Percutaneous coronary intervention (PCI) of coronary chronic total occlusions (CTO) still represents a challenge in the field of interventional cardiology. Despite the rate of peri-procedural complications has decreased over the years, it remains higher than in non-CTO PCI. Coronary perforations are among the most common and serious complications. Furthermore CTO recanalization carries a risk of unique and specific complications such as donor vessel injury and equipment loss or entrapment. Other infrequent complications of non-CTO PCI such as contrast induced renal dysfunction and radiation skin injury, assume more relevance in this subset given the length and complexity of these procedures. Operators facing CTO percutaneous treatment should be aware of the potential complications and the available strategies for prevention and management, to achieve procedural success.
