Use of the ClearSight® System for Continuous Noninvasive Hemodynamic Monitoring during Heart Valve Interventions: Review of the Literature and Single-Site Experience.

Heart Surg Forum 2018 Nov 14;21(6):E476-E483. Epub 2018 Nov 14.

Interventional Echocardiography, Structural Heart Program, Banner - University Medical Center Phoenix, Phoenix, AZ, USA.

During interventional and structural cardiology procedures, such as mitral valve (MitraClip, BMV), aortic valve (TAVR, BAV), tricuspid valve (MitraClip), left atrial appendage (Watchman, Lariat), atrial septum (ASD/PFO closure), and coronary artery intervention (high-risk PCI), among others, patients are at a high risk of hemodynamic instability and require continuous monitoring. This is conventionally achieved through arterial catheterization and transpulmonary thermodilution. However, such invasive techniques are time-consuming and have been associated with steep learning curves, vascular complications, and increased risk of infection. Read More

Performance comparison of ventricular and arterial dP/dt for assessing left ventricular systolic function during different experimental loading and contractile conditions.

Crit Care 2018 11 29;22(1):325. Epub 2018 Nov 29.

Department of Critical Care Medicine, University of Pittsburgh School of Medicine, Pittsburgh, USA.

Background: Maximal left ventricular (LV) pressure rise (LV dP/dt), a classical marker of LV systolic function, requires LV catheterization, thus surrogate arterial pressure waveform measures have been proposed. We compared LV and arterial (femoral and radial) dP/dt to the slope of the LV end-systolic pressure-volume relationship (Ees), a load-independent measure of LV contractility, to determine the interactions between dP/dt and Ees as loading and LV contractility varied.

Methods: We measured LV pressure-volume data using a conductance catheter and femoral and radial arterial pressures using a fluid-filled catheter in 10 anesthetized pigs. Read More

Epigenetically modified cardiac mesenchymal stromal cells limit myocardial fibrosis and promote functional recovery in a model of chronic ischemic cardiomyopathy.

Basic Res Cardiol 2018 Nov 16;114(1). Epub 2018 Nov 16.

Institute of Molecular Cardiology, Division of Cardiovascular Medicine, University of Louisville, 580 S. Preston Street, Louisville, KY, 40292, USA.

Preclinical investigations support the concept that donor cells more oriented towards a cardiovascular phenotype favor repair. In light of this philosophy, we previously identified HDAC1 as a mediator of cardiac mesenchymal cell (CMC) cardiomyogenic lineage commitment and paracrine signaling potency in vitro-suggesting HDAC1 as a potential therapeutically exploitable target to enhance CMC cardiac reparative capacity. In the current study, we examined the effects of pharmacologic HDAC1 inhibition, using the benzamide class 1 isoform-selective HDAC inhibitor entinostat (MS-275), on CMC cardiomyogenic lineage commitment and CMC-mediated myocardial repair in vivo.

Carl R. Darnall Army Medical Center, Emergency Medicine Residency, 36065 Santa Fe Ave, Fort Hood, TX 76544, United States of America. Electronic address:

Background: Brugada pattern is a well-known pathological finding on electrocardiogram (ECG) which increases the likelihood of cardiac arrest due to ventricular arrhythmia. These cases generally present in younger patients without evidence of an electrolyte abnormality, structural heart disease, or cardiac ischemia. In many instances, this pattern is either hidden on initial presentation or presents as an incidental finding on an EKG. Read More

Swan, Ganz, and Their Catheter: Its Evolution Over the Past Half Century.

Ann Intern Med 2018 Nov;169(9):636-642

Harvard Medical School and Brigham and Women's Hospital, Boston, Massachusetts (S.P.D.).

Jeremy Swan and William Ganz developed their eponymous pulmonary artery (PA) catheter in the 1970s and, in the process, revolutionized measurement of cardiac output, pressures within the left side of the heart, and resistance in systemic and pulmonary circulations. Their invention enabled diagnostic measurements at the bedside and contributed to the birth of critical care medicine; technologic advances preceding the PA catheter generally could not be used at the bedside and required patients to be stable enough to be taken to the catheterization laboratory. Swan and Ganz worked in the same department but had quite dissimilar backgrounds and personalities. Read More

Successful Transcatheter Atrial Septal Defect Closure Prior to Coronary Artery Bypass Grafting Using Anti-Congestive Therapies and Intraaortic Balloon Pumping in a Patient with Severe Ischemic Cardiomyopathy and Triple-Vessel Coronary Artery Disease.

Int Heart J 2018 Nov 25;59(6):1480-1484. Epub 2018 Oct 25.

Department of Cardiovascular Medicine, National Cerebral and Cardiovascular Center.

In patients with an atrial septal defect (ASD) and left ventricular (LV) dysfunction associated with coronary artery disease (CAD), to avoid the development of acute left heart failure (HF) and an increase in myocardial oxygen consumption following ASD closure, it is conceivable that coronary artery revascularization should be performed prior to ASD closure. We report the case of a 67-year-old man with a large secundum ASD and LV ejection fraction of 15.6% resulting from severe ischemic cardiomyopathy and triple-vessel CAD, both of which contributed to biventricular HF characterized by high left-to-right shunt (Qp:Qs of 7.
