Factors contributing to radiation dose for patients and operators during diagnostic cardiac angiography.

Introduction: Diagnostic coronary angiography (CA) uses ionising radiation with relatively high doses, which impact on both patients and staff. This study sought to identify which patient and procedural factors impact patient and operator dose the most during CA.

Methods: Patient and procedure related variables impacting on Kerma area product (P ) and operator dose (OD) were collected for 16 months.

Factors Contributing to Acute Kidney Injury and the Impact on Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement.

Background: Transcatheter aortic valve replacement (TAVR) patients are at a high risk of acute kidney injury (AKI). This study aimed to investigate AKI and the relationship with iodinated contrast media (ICM), whether there are significant pre- or peri- procedural variables predicting AKI, and whether AKI impacts on hospital length of stay and mortality.

Methods: Serum creatinine (SC) levels pre- and post- (peak) TAVR were recorded in 209 consecutive TAVR patients.

Simultaneous two-vessel very-late stent thrombosis of everolimus-eluting stents.

Very-late stent thrombosis is a rare complication. Several factors related to the patient, procedure, and premature discontinuation of antiplatelet therapy are known to contribute to its occurrence. This report describes the case of a 40-year-old patient with simultaneous two-vessel stent thrombosis (left anterior descending and right coronary arteries) 31 months after everolimus-eluting stent implantation.
