Stabilization of unstable periodic orbits in dc drives [PDF]

arXiv, 2014
Electric drive using dc shunt motor or permanent magnet dc (PMDC) motor as prime mover exhibits bifurcation and chaos. The characteristics of dc shunt and PMDC motors are linear in nature. These motors are controlled by pulse width modulation (PWM) technique with the help of semiconductor switches.

Transcatheter device closure of atrial septal defect and patent foramen ovale in Malta [PDF]

, 2008
Significant atrial septal defects (ASD) are closed, surgically or through a transcatheter device, in order to avoid pulmonary hypertension in late life.

Microaxial pump‐supported coronary surgery without CPB to optimize outcome in severely impaired left ventricles

ESC Heart Failure, EarlyView.
Abstract Aims Cardiopulmonary bypass (CPB) is the standard approach for coronary artery bypass grafting (CABG) in advanced ischaemic cardiomyopathy. Microaxial pump support has been envisioned to allow for beating‐heart CABG without CPB (MPCAB), thereby avoiding CPB‐inherent complications.

Left atrial to coronary sinus shunting in more advanced heart failure with preserved ejection fraction

ESC Heart Failure, EarlyView.
Abstract Aims Inter‐atrial shunt device therapy has shown mixed results in clinical trials, with clinical ‘non‐responders’ typically showing features of more advanced heart failure. We aimed to analyse the haemodynamic and clinical response of a novel left atrial to coronary sinus (LA‐CS) shunt device in patients with higher natriuretic peptide (NP ...

Is the adjustable lumbo-peritoneal shunt a valid option for managing symptomatic idiopathic intracranial hypertension? A case report of a multidisciplinary management

Interdisciplinary Neurosurgery, 2019
Background: Idiopathic intracranial hypertension is a rare disorder, characterized by raised intracranial pressure with no recognizable cause. Headache, decreased visual acuity and papilledema are the main clinical manifestations.

Multi‐microRNA diagnostic panel for heart failure with preserved ejection fraction in preclinical and clinical settings

ESC Heart Failure, EarlyView.
Abstract Aims Heart failure with preserved ejection fraction (HFpEF) is a complex syndrome accounting for half of heart failure cases. Although natriuretic peptides are the most accepted and extensively used biomarkers for heart failure, their diagnostic accuracy for HFpEF remains debatable.

Left ventricular decompression in paediatric veno‐arterial extracorporeal life support: Reviewing the evidence

ESC Heart Failure, EarlyView.
Abstract Veno‐arterial extracorporeal life support (VA ECLS) is crucial for neonatal and paediatric patients with severe circulatory collapse but may cause left ventricular (LV) overload, affecting myocardial recovery and causing complications. Evidence on optimal LV decompression strategies in paediatric patients remains limited.

Quality of life in heart failure. The heart of the matter. A scientific statement of the Heart Failure Association and the European Association of Preventive Cardiology of the European Society of Cardiology

European Journal of Heart Failure, EarlyView.
For most patients with chronic, progressive illnesses, maintaining good quality of life (QoL), with preserved functional capacity, is just as crucial as prolonging survival. Patients with heart failure (HF) experience much worse QoL and effort intolerance than both the general population and people with other chronic conditions, since they present a ...
