Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High‐Definition Intravascular Ultrasound in Non‐ST‐Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).

Gaussian Processes for HRF estimation for BOLD fMRI [PDF]

open access: yesarXiv, 2017
We present a non-parametric joint estimation method for fMRI task activation values and the hemodynamic response function (HRF). The HRF is modeled as a Gaussian process, making continuous evaluation possible for jittered paradigms and providing a variance estimate at each point.

Closure of a Late‐Onset Iatrogenic Left Ventricular Pseudoaneurysm Caused by Erosion of an Apical Muscular VSD Device

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report the case of a 3‐year‐old asymptomatic girl (12 kg, 96 cm) who was diagnosed with a large iatrogenic left ventricular pseudoaneurysm (LVP) on follow‐up ultrasound, 14 months after apical muscular ventricular septal defect (VSD) closure with a 10 mm Amplatzer Muscular VSD occluder (Abbott, USA) due to device erosion.

Treating a 20 mm Hg Gradient Alleviates Myocardial Hypertrophy in Experimental Aortic Coarctation [PDF]

open access: yes, 2017
Background Children with coarctation of the aorta (CoA) can have a hyperdynamic and remodeled left ventricle (LV) from increased afterload. Literature from an experimental model suggests the putative 20 mm Hg blood pressure gradient (BPG) treatment ...

Comparison of Fractional Flow Reserve and Myocardial Perfusion Imaging in Saphenous Vein Grafts

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Revascularization decision‐making for saphenous vein grafts (SVGs) relies on angiographic lesion severity estimation, as studies on fractional flow reserve (FFR) for detecting ischemia in SVGs are scarce. Aims To compare FFR and quantitative coronary angiography (QCA) of SVGs against myocardial perfusion imaging (MPI) and to ...
