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. ...

background : cardiovascular operations are associated with an inherent bleeding tendency that sometimes leads to severe bleeding and transfusion requirement. pharmacological intervention to minimize post-bypass bleeding and blood product transfusions has received increasing attention from both medical and economic viewpoints. methods: this double-blind, randomized, placebo-controlled clinical t...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...

background: euroscore is a simple and rigorous risk stratification model and is, thus, commonly used in predicting the early and late outcomes of cardiac surgery across the world. we aimed to assess the discriminative power of the euroscore model to predict postoperative morbidity and total prolonged length of stay in hospital (los) and intensive care unit (icu) stay in an iranian group of card...
