Connecting Ventricular Assist Devices to the Aorta: a Numerical Model

Alfio Quarteroni, Simone Deparis, Jean Bonnemain

Mechanical circulatory support, in particular ventricular assist devices (VAD), has been recently proposed as an alternative to transplantation in the treatment of terminal heart failure in the context of the lack of donors and raising number of patients o ...

Artificial Muscle for End-Stage Heart Failure

Alexandre Michalis, Didier Locca, Ludwig Von Segesser

We describe a device made of artificial muscle for the treatment of end-stage heart failure as an alternative to current heart assist devices. The key component is a matrix of nitinol wires and aramidic fibers called Biometal muscle (BM). When heated elect ...

A Multi-Lead Ecg Classification Based On Random Projection Features

David Atienza Alonso, Francisco Javier Rincon Vallejos, Iva Bogdanova Vandergheynst

This paper presents a novel method for classification of multi-lead electrocardiogram (ECG) signals. The feature extraction is based on the random projection (RP) concept for dimensionality reduction. Furthermore, the classification is performed by a neuro ...

Study of the effect of rapid pacing of atrial fibrillation on the non-paced atrium

Jean-Marc Vesin, Laurent Renaud Uldry, Lukas Kappenberger

Purpose: Experimental studies showed that local capture of atrial fibrillation (AF) by rapid pacing was possible in humans. However, contradictory observations were reported on its effect at distant atrial sites. The present model-based study investigated ...

Human embryonic stem cell-derived microvascular grafts for cardiac tissue preservation after myocardial infarction

Jeffrey Alan Hubbell

We present use of a synthetic, injectable matrix metalloproteinase (MMP)- responsive, bioactive hydrogel as an in situ forming scaffold to deliver thymosin beta 4 (T beta 4), a pro-angiogenic and pro-survival factor, along with vascular cells derived from ...

Direct electric stimulation using a battery-operated device for induction and modulation of colonic contractions in pigs

Jean-Marc Vesin, Vincent Schlageter, Pavel Kucera, Mattia Bertschi

Direct electrical stimulation of the colon offers a promising approach for the induction of propulsive colonic contractions by using an implantable device. The objective of this study was to assess the feasibility to induce colonic contractions using a com ...

ECG-based prediction of atrial fibrillation development following coronary artery bypass grafting

Sinisa Sovilj

In patients undergoing coronary artery bypass grafting (CABG) surgery, post-operative atrial fibrillation (AF) occurs with a prevalence of up to 40%. The highest incidence is seen between the second and third day after the operation. Following cardiac surg ...

Non-Invasive Imaging of Cardiac Activation and Recovery

The sequences of activation and recovery of the heart have physiological and clinical relevance. We report on progress made over the last years in the method that images these timings based on an equivalent double layer on the myocardial surface serving as ...

Transfer matrices for deriving the vectorcardiogram: a consumer guide

Zenichi Ihara

Background In the literature, several different transfer matrices have been presented for deriving the vectorcardiogram (VCG) from the signals observed using a limited set of electrodes. Even when the electrode locations were identical, like 9 of the stand ...
