UNLABELLED Atrioventricular bypass tract deflections were recorded in five patients with the Wolff-Parkinson-White syndrome using standard, closely spaced (5 mm) electrode catheters. Three right paraseptal and two left-sided Kent bundles were recorded at the level of the tricuspid valve on the His bundle catheter and in the coronary sinus, respectively. Characteristics of the bypass tracts were...

OBJECTIVE This study aimed to compare the effects of two different perfusion techniques: conventional cardiopulmonary bypass and miniature cardiopulmonary bypass in patients undergoing cardiac surgery at the University Hospital of Santa Maria--RS. METHODS We perform a retrospective, cross-sectional study, based on data collected from the patients operated between 2010 and 2013. We analyzed th...

background: peripheral vascular injury associated with lower limb trauma is a well-known emergency. the experience for the management of popliteal artery trauma have mainly come from managing the traumas of military personnels during iran-iraq war. the present study compared the effects of two currently-used surgical techniques in the management of popliteal trauma, namley femoropopliteal bypas...

BACKGROUND Long-term patency of extracranial-to-intracranial (EC-IC) vein bypass is poorly understood. OBJECTIVE We report our experience of patency of arterial pedicle grafts and interposition vein grafts for the purpose of EC-IC bypass. METHODS We analyzed 294 consecutive patients who underwent 178 intracranial arterial pedicle bypass procedures and 152 intracranial vein bypass procedures...

heparin- induced thrombocytopenia (hit) is an antibody mediated adverse effect of heparin therapy which is classified into two subtypes, hit i which is non-immune, spontaneously reversible thrombocytopenia and; hit ii which is an autoimmune-mediated adverse effect of heparin therapy. in this case report, we described a 65-year old male patient with hit ii after coronary artery bypass grafting. ...

Increasing societal pressures (e.g., population growth and urbanization) are driving land use change practices in coastal areas that could potentially alter the hydrodynamics sediment transport patterns near inlets ways might exacerbate existing shoaling conditions. To investigate potential impact of development, a numerical model is used to predict long-term evolution an idealized lagoonal-typ...

Abstract Magnetorheological (MR) dampers with bypass arrangements and combined annular-radial fluid flow channels have shown superior performance compared to conventional MR single annular/radial gaps. Achieving a higher controllable dynamic force range low off-state but high on-state damping is yet significant challenge for developing payload ground vehicle suspensions. This paper presents the...

Cryptocurrency networks, such as Bitcoin, have emerged a distributed alternative to traditional centralized financial transaction networks. However, there are major challenges in scaling up the throughput of Lightning network and Spider alternates that build bidirectional payment channels on top cryptocurrency networks using smart contracts, enable fast transactions bypass Blockchain. In this a...
