Enlargement Ratio May Predict Device Size in Elderly Patients with Atrial Septal Defect.

Background And Objectives: Balloon sizing remains the main technique for determining occluder device size for atrial septal defects (ASDs). New evidence has proposed that accurate estimation of device size could be possible without using the balloon technique. Operators have predicted the amount of possible enlargement depending on their experiences.

Association of mean platelet volume with presence of non-viable myocardium in ischaemic cardiomyopathy.

Background: Parameters derived from complete blood count, such as mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), have recently been proposed as measures of inflammation in addition to C-reactive protein (CRP), a classical inflammatory marker. Significant association of these parameters with atherosclerosis and complications have increasingly been reported.

Aim: The aim of the study is to evaluate the relationship between these parameters and the presence of myocardial viability assessed with positron emission tomography (PET) in patients with ischaemic cardiomyopathy (ICM).
