Dynamic Piston Function of the Mitral Annulus to Assess Early Left Ventricular Diastolic Filling: A Proof of Concept Study.

Cardiol Ther 2019 Feb 16. Epub 2019 Feb 16.

Cardiovascular Medicine Division, University of Puerto Rico School of Medicine, San Juan, PR, USA.

Introduction: Early left ventricular (LV) filling has been described as an asymmetric toroidal vortex ring of blood entering the LV upon opening of the mitral valve. This phenomenon is in part responsible for cyclical changes in LV volumes during the cardiac cycle and also contributes to the apical and basal longitudinal displacements of the mitral annulus (MA). Although MA early diastolic (e') velocities have been used to assess early LV filling characteristics, accurate distinction between normal aging and pathological diastolic dysfunction (DD) might be challenging at times.

Interact Cardiovasc Thorac Surg 2019 Feb 14. Epub 2019 Feb 14.

Department of Cardiovascular Surgery, German Heart Centre Munich, Munich, Germany.

Objectives: Our goal was to assess the viability of an alternative anchoring design for a transcatheter aortic valve based on a form-fitting principle with a self-expanding nitinol frame to reduce issues related to excess radial force.

Methods: A 26-mm outer diameter prototype of a self-expanding nitinol frame was developed to reduce the amount of necessary radial force by utilizing additional anchoring via protruding arms in each aortic sinus, thus allowing for a form-fitting principle as well as the coaxial self-alignment of the valve inside the native anatomy. The prototype valve was implanted via a transapical approach in the orthotopic position in 2 sheep. Read More

Comprehensive Evaluation of Right Heart Performance and Pulmonary Hemodynamics in Neonatal Pulmonary Hypertension : Evaluation of cardiopulmonary performance in neonatal pulmonary hypertension.

Curr Treat Options Cardiovasc Med 2019 Feb 15;21(2):10. Epub 2019 Feb 15.

Section of Neonatology, Department of Pediatrics, Texas Children's Hospital and Baylor College of Medicine, Houston, TX, USA.

Purpose Of Review: Pulmonary hypertension is characterized by an elevation of pulmonary artery pressures and prolonged exposure of the right ventricle to high afterload that collectively contribute to morbidity and mortality in both the term and preterm infants. This review summarizes the pathogenesis, etiologies, and hemodynamic profiles of the conditions that result in pulmonary hypertension in neonates. We explore the application of echocardiographic techniques for the assessment of right ventricular performance and pulmonary hemodynamics that enhance and guide the diagnosis and management strategies in neonates.

The Correlation between Severity of Neurological Impairment and Left Ventricular Function in Patients after Acute Ischemic Stroke.

J Clin Med 2019 Feb 5;8(2). Epub 2019 Feb 5.

Division of Cardiology, Department of Internal Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, Kaohsiung 83301, Taiwan.

Despite left ventricular (LV) dysfunction increases the risk of incidental acute ischemic stroke (AIS), the association between LV function and severity of neurological deficits after AIS remains unclear. Between November 2015 and October 1017, a total of 99 AIS patients were prospectively enrolled and categorized into two groups based on National Institute of Health Stroke Scale (NIHSS). The AIS patients with NIHSS <6 were allocated into Group 1 ( = 50) and those with NIHSS ≥6 were into Group 2 ( = 49). Read More

Associations of High Intensities on Magnetization-Prepared Rapid Acquisition with Gradient Echo with Aortic Complicated Lesions in Ischemic Stroke Patients.

Cerebrovasc Dis 2019 Feb 14;47(1-2):15-23. Epub 2019 Feb 14.

Department of Cerebrovascular Medicine, National Cerebral and Cardiovascular Center, Suita, Japan.

Background: Aortic complicated lesions (ACLs) are key parameters for evaluating aortic embolic sources in embolic stroke, and are usually diagnosed using transesophageal echocardiography (TEE). However, alternative methods for diagnosing ACLs have not been well established. We investigated associations between high-intensity areas on T1-weighted imaging (T1WI) with magnetization-prepared rapid acquisition with gradient echo (MPRAGE) and ACLs on TEE among ischemic stroke patients.

Treatment with mononuclear cell populations improves post-infarction cardiac function but does not reduce arrhythmia susceptibility.

PLoS One 2019 14;14(2):e0208301. Epub 2019 Feb 14.

Department of Cardiology, University of Bonn, Bonn, Germany.

Background: Clinical and experimental data give evidence that transplantation of stem and progenitor cells in myocardial infarction could be beneficial, although the underlying mechanism has remained elusive. Ventricular tachyarrhythmia is the most frequent and potentially lethal complication of myocardial infarction, but the impact of mono nuclear cells on the incidence of ventricular arrhythmia is still not clear.

Objective: We aimed to characterize the influence of splenic mononuclear cell populations on ventricular arrhythmia after myocardial infarction. Read More
