In vivo coronary lesion differentiation with computed tomography angiography and intravascular ultrasound as compared to optical coherence tomography.

Background: In vitro studies have shown the feasibility of coronary lesion grading with computed tomography angiography (CTA), intravascular ultrasound (IVUS) and optical coherence tomography (OCT) as compared to histology, whereas OCT had the highest discriminatory capacity.

Objective: We investigated the ability of CTA and IVUS to differentiate between early and advanced coronary lesions in vivo, OCT serving as standard of reference.

Methods: Multimodality imaging was prospectively performed in 30 NSTEMI patients.

A randomised controlled study of standard versus accelerated deflation of the Terumo radial band haemostasis device after transradial diagnostic cardiac catheterisation.

Background: Radial access is the preferential access route in patients undergoing diagnostic coronary angiography. We hypothesised that we could reduce hospital stay and improve patient comfort by accelerated deflation of the radial compression device (Terumo radial band).

Aims: The aim of this study was to compare accelerated pressure reduction with a standard Terumo radial band protocol with regard to local bleeding complications and reported pain scores after cardiac catheterisation.

Emergency transcatheter aortic valve implantation in patients with severe aortic regurgitation and a left ventricle assist device: A case report and systematic review.

Background: Cardiogenic shock due to severe aortic regurgitation in patients with left ventricle assist devices is a life threatening condition. Here, we consider transcatheter aortic valve implantation as a treatment option.

Methods And Results: A patient with a left ventricle assist device was presented to us with cardiogenic shock due to severe aortic regurgitation.

Repositioning of an intraventricular dislocated aortic valve during transcatheter aortic valve implantation.

The case is presented of a 75-year-old man referred for transcatheter aortic valve implantation. During the procedure the prosthetic aortic valve became dislocated into the left ventricle shortly after expansion. The subsequent steps taken to reposition the valve using only materials at hand are described.

Effect of metformin on left ventricular function after acute myocardial infarction in patients without diabetes: the GIPS-III randomized clinical trial.

Importance: Metformin treatment is associated with improved outcome after myocardial infarction in patients with diabetes. In animal experimental studies metformin preserves left ventricular function.

Objective: To evaluate the effect of metformin treatment on preservation of left ventricular function in patients without diabetes presenting with ST-segment elevation myocardial infarction (STEMI).
