OBJECTIVES This study sought to compare radial and femoral approaches in patients presenting with ST-segment elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PCI) by high-volume operators experienced in both access sites. BACKGROUND The exact clinical benefit of the radial compared to the femoral approach(More)
The tissue factor plays a crucial role in initiating blood coagulation after plaque rupture in patients with acute coronary syndrome. It is abundant in atherosclerotic plaques. Moreover, P-selectin, some cytokines, endotoxin and immune complexes can stimulate monocytes and induce the tissue factor expression on their surface. The aim of the study was to(More)
Pseudoaneurysm of the ascending aorta is a high-risk complication following cardiac surgery. The present report describes excellent two-year follow-up results after the percutaneous closure of a very large pseudoaneurysm with an Amplatzer atrial septal defect occluder. The original cavity in the anterior mediastinum with maximal diameter 15 cm remained as(More)
INTRODUCTION Reports about the efficacy of precordial thump (PT) in the termination of ventricular arrhythmias (VA) vary widely. Very little recent data about the mechanical termination of VA induced during programmed ventricular stimulation are available. METHODS We prospectively studied 485 consecutive patients (May 2001 to December 2007) who underwent(More)
Isolated thoracic aortitis (ITA) is diagnosed in a variable proportion of patients operated on for dilation/aneurysm of ascending aorta. The etiopathogenesis of ITA remains unclear. We studied 11 cases of ITA in order to determine the role of IgG4-mediated immune responses in its pathogenesis. The series included nine women and two men aged 52-79 years. All(More)
UNLABELLED What's known on the subject? and What does the study add? Surgical treatment of renal cell carcinoma (RCC) with tumour thrombus extending into the right atrium remains, despite its complexity and specific technical aspects, the only radical therapeutic option. This single-centre study, unique in size for this rare condition, reports early and(More)
A standardized approach to aortic valve repair is described associating a physiological remodeling of the root, with resuspension of cusp effective height and a subvalvular aortic annuloplasty using an external expansible ring. This device achieves a complete calibrated annuloplasty, in order to increase cups coaptation height and protect the repair. This(More)
Enhanced expression of tissue factor (TF) may result in thrombosis contributing to acute clinical consequences of coronary artery disease. Several studies demonstrated elevated plasma levels of TF in patients with acute coronary syndrome (ACS). The aim of our study was to compare the concentrations of TF in coronary sinus (CS), proximal part of the left(More)
In 22 patients with ischaemic heart disease and conditions after infarction and angina pectoris a coronarographic examination was made as well as other auxiliary examinations incl. a complex analysis of the electrical cardiac field (KAESP) (23), using a Cardiac apparatus (manufacturer ZPA Cakovice). Using the KAESP method fibroses in the heart muscle were(More)
The RE-LY study compared dabigatran in the dose of 150 mg and 110 mg twice daily, without laboratory monitoring, with the conventional treatment with warfarin dosed according to INR in 18,113 patients with non-valvular atrial fibrillation and high risk of embolisation. The incidence of cerebrovascular events and systemic embolisation was 1.69% per year in(More)
