Determinants of percutaneous coronary intervention success in repeat chronic total occlusion procedures following an initial failed attempt.

Aim: To investigate the rates and determinants of success of repeat percutaneous coronary intervention (PCI) following an initial failed attempt at recanalising the chronic total occlusions (CTO) percutaneously.

Methods: In 445 consecutive first attempt CTO-PCI procedures in our institution, procedural failure occurred in 149 (33.5%).

Rescue percutaneous intervention for acute complications of coronary artery surgery.

Although percutaneous interventions in the context of perioperative coronary artery surgery ischaemic complications are not unusual, this type of secondary revascularisation is rarely addressed in the literature. Information on aspects such as complications and clinical outcome is limited, in spite of this being a high-risk population. To shed light on the subject, the present article presents a systematic review of the literature on this topic, along with the analysis of the institutional experience at a centre with high surgical and percutaneous revascularisation case volume.
