Predictors and trends of contrast use and radiation exposure in a large cohort of patients treated with percutaneous coronary interventions: Chronic total occlusion analysis based on a national registry.

Background: The aim herein, was to assess predictors and current trends of radiation exposure and total contrast amount use in patients treated with percutaneous coronary intervention within chronic total occlusion (CTO PCI) and non-CTO PCI.

Methods: Based on a nationwide registry (ORPKI), 535,857 patients treated with PCI between 2014 and 2018 were analysed. The study included 12,572 (2.

Diabetes and periprocedural outcomes in patients treated with rotablation during percutaneous coronary interventions.

Background: This study is to assess differences in periprocedural outcomes among diabetic and non-diabetic patients treated with percutaneous coronary intervention (PCI) and rotational atherectomy (RA).

Methods: Under assessment were 221,187 patients from the Polish Cardiovascular Intervention Society national registry (ORPKI) including all PCIs performed in Poland in 2015 and 2016. Data was extracted of 975 patients treated with RA - 336 (34.

Predictors of periprocedural complications in patients undergoing percutaneous coronary interventions within coronary artery bypass grafts.

Background: During the first decade following the coronary bypass grafting, at least ten percent of the patients require percutaneous coronary interventions (PCI) due to graft failure. Saphenous vein grafts (SVG) are innately at a higher risk of periprocedural complications. The present study aimed to investigate predictors of periprocedural complications of PCI within coronary artery bypass grafts.
