Impact of cognitive behavioral therapy on depression symptoms after transcatheter aortic valve replacement: A randomized controlled trial.

Background: Depression is a significant concern after cardiac surgery and has not been studied in patients undergoing transcatheter aortic valve replacement (TAVR). We sought to examine the prevalence of pre-procedure depression and anxiety symptoms and explore whether brief bedside cognitive behavioral therapy (CBT) could prevent post-TAVR psychological distress.

Methods: We prospectively recruited consecutive TAVR patients and randomized them to receive brief CBT or treatment as usual (TAU) during their hospitalization.

Cytokines profile of reverse cardiac remodeling following transcatheter aortic valve replacement.

Objective: Previous studies have suggested that cytokines and growth factors may predict ventricular recovery following aortic valve replacement (AVR). The primary objective of this study was to identify cytokines that predict ventricular recovery following transcatheter AVR (TAVR).

Methods: We prospectively enrolled 121 consecutive patients who underwent TAVR.

Multimodality Molecular Imaging of Cardiac Cell Transplantation: Part II. In Vivo Imaging of Bone Marrow Stromal Cells in Swine with PET/CT and MR Imaging.

Purpose To quantitatively determine the limit of detection of marrow stromal cells (MSC) after cardiac cell therapy (CCT) in swine by using clinical positron emission tomography (PET) reporter gene imaging and magnetic resonance (MR) imaging with cell prelabeling. Materials and Methods Animal studies were approved by the institutional administrative panel on laboratory animal care. Seven swine received 23 intracardiac cell injections that contained control MSC and cell mixtures of MSC expressing a multimodality triple fusion (TF) reporter gene (MSC-TF) and bearing superparamagnetic iron oxide nanoparticles (NP) (MSC-TF-NP) or NP alone.

Multimodality Molecular Imaging of Cardiac Cell Transplantation: Part I. Reporter Gene Design, Characterization, and Optical in Vivo Imaging of Bone Marrow Stromal Cells after Myocardial Infarction.

Purpose To use multimodality reporter-gene imaging to assess the serial survival of marrow stromal cells (MSC) after therapy for myocardial infarction (MI) and to determine if the requisite preclinical imaging end point was met prior to a follow-up large-animal MSC imaging study. Materials and Methods Animal studies were approved by the Institutional Administrative Panel on Laboratory Animal Care. Mice (n = 19) that had experienced MI were injected with bone marrow-derived MSC that expressed a multimodality triple fusion (TF) reporter gene.

The impact of downstream coronary stenosis on fractional flow reserve assessment of intermediate left main coronary artery disease: human validation.

Objectives: The aim of this study was to determine the impact of downstream coronary stenosis in the left anterior descending coronary artery (LAD) or left circumflex coronary artery (LCx) on the assessment of fractional flow reserve (FFR) across an intermediate left main coronary artery (LMCA) stenosis in humans with the pressure wire positioned in the nondiseased downstream vessel.

Background: Accurate assessment of intermediate LMCA disease is critical for guiding decisions regarding revascularization. In theory, FFR across an intermediate LMCA stenosis will be affected by downstream disease, even if the pressure wire is positioned in the nondiseased downstream vessel.

PFO and paradoxical embolism producing events other than stroke.

Background: A patent foramen ovale (PFO) is a risk factor for cerebral events such as cryptogenic stroke, transient ischemic attacks, and migraine headaches. Far less commonly, PFO is associated with non-cerebral, paradoxical systemic embolic events such as myocardial infarction (MI), renal infarct, and limb ischemia. This report details the incidence of systemic paradoxical emboli at our institution.

The association of patent foramen ovale morphology and stroke size in patients with paradoxical embolism.

Background: Patent foramen ovale (PFO) has been implicated in the pathogenesis of cryptogenic stroke through paradoxical embolization to the cerebral circulation. This study evaluated the relationship between the morphological and functional size of the PFO by echocardiography compared with cerebral infarct volume identified on MRI.

Methods And Results: Patients who were referred to interventional cardiology with the diagnosis of cryptogenic stroke were included and had either a transesophageal echocardiogram or an intracardiac echo and a brain MRI at the time of stroke.

Five-year experience with percutaneous closure of patent foramen ovale.

Patent foramen ovale (PFO) has been implicated in the pathogenesis of cryptogenic stroke, arterial desaturation, decompression illness, and migraine headache (MH). This study evaluated the safety of percutaneous transcatheter PFO closure in patients with cryptogenic stroke, transient ischemic attack, or arterial desaturation. Additionally, symptomatic reduction in MH was determined after interatrial shunt closure.

Association of interatrial shunts and migraine headaches: impact of transcatheter closure.

Objectives: To examine the relationship between patent foramen ovale (PFO) or atrial septal defect (ASD) with the incidence of migraine headache (MHA) and assess whether closure of the interatrial shunt in patients with MHA would result in improvement of MHA.

Background: Migraine headache is present in 12% of adults and has been associated with interatrial communications. This study examined the relationship between PFO or ASD with the incidence of MHA and assessed whether closure of the interatrial shunt in patients with MHA would result in improvement of MHA.
