The complex anatomy of the aortic annulus warrants the use of three dimensional (3D) modalities for prosthesis sizing in transcatheter aortic valve implantation (TAVI). Multislice computed tomography (MSCT) has been used for this purpose, but its use may be restricted because of contrast administration. 3D transesophageal echocardiography (3D-TEE) lacks this limitation and data on comparison with MSCT is scarce. We compared 3D-TEE with MSCT for prosthesis sizing in TAVI. ⋯ Annulus diameters and areas for pre-procedural TAVI assessment by 3D-TEE are significantly smaller than MSCT with exception of sagittal diameters. Using sagittal diameters, both modalities predicted well final prosthesis size and excellent procedural results were obtained. 3D-TEE can thus be a useful alternative in patients with contraindications to MSCT.

Randomized Controlled Trial Observational Study
Peri-procedural tight glycemic control during early percutaneous coronary intervention up-regulates endothelial progenitor cell level and differentiation during acute ST-elevation myocardial infarction: effects on myocardial salvage.
We examined the effects of peri-procedural intensive glycemic control during early percutaneous coronary intervention (PCI) on the number and differentiation of endothelial progenitor cells (EPCs) and myocardial salvage (MS) in hyperglycemic patients with first ST-elevation myocardial infarction (STEMI). ⋯ Optimal peri-procedural glycemic control, by increasing EPC number and their capability to differentiate, may improve the myocardial salvage.

Randomized Controlled Trial Multicenter Study
Safety of pacemaker and implantable cardioverter-defibrillator implantation during uninterrupted warfarin treatment--the FinPAC study.
Periprocedural management of oral anticoagulation (OAC) in patients undergoing cardiac rhythm management (CRM) device implantation is controversial. Prior studies demonstrate that uninterrupted OAC may be safe, but limited data from randomized trials exist. ⋯ Our randomized study demonstrates that CRM devices can be safely implanted without discontinuation of warfarin treatment.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized trial of platelet reactivity monitoring-adjusted clopidogrel therapy versus prasugrel therapy to reduce high on-treatment platelet reactivity.
Peri-procedural platelet reactivity (PR) inhibition is critical in patients undergoing percutaneous coronary intervention (PCI). High on-treatment PR (HTPR) was associated with recurrent ischemic events in acute coronary syndrome (ACS) patients undergoing PCI. We aimed to compare a strategy of clopidogrel loading dose-adjustment (CDA) according to PR monitoring with standard prasugrel therapy to reduce the rate of patients exhibiting HTPR. ⋯ In the present study, PR monitoring was superior to standard prasugrel therapy to reduce the rate of HTPR in ACS patients. In addition such strategy reduced the number of patients with very low PR.

Multicenter Study Comparative Study Clinical Trial
Comparison of the diagnostic and prognostic values of B-type and atrial-type natriuretic peptides in acute heart failure.
We compared diagnostic and prognostic properties of brain natruiretic peptide (BNP), proBNP, NT-proBNP and MR-pro-atrial natriuretic peptide (ANP) in patients admitted with shortness of breath (SOB). ⋯ Our study provides firm evidence that all NPs perform equally well for diagnostic purposes, and that MR-proANP has long term prognostic value in patients with acute heart failure.
