OBJECTIVE Modern neuronavigation systems lack spatial accuracy during ongoing surgical procedures because of increasing brain deformation, known as brain shift. Intraoperative magnetic resonance imaging was used for quantitative analysis and visualization of this phenomenon. METHODS For a total of 64 patients, we used a 0.2-T, open-configuration, magnetic(More)
OBJECTIVE In acute type A aortic dissection, the extension of repair to downstream aorta has been controversially discussed. We present the early results of a multicenter study using a hybrid stent graft prosthesis. METHODS Between January 2005 and January 2010, the data from 191 patients after combined proximal aortic replacement and antegrade stent(More)
Two patients with congenital atresia of the left coronary artery ostium underwent myocardial revascularization at the age of three years and three months, respectively. The patients were admitted to the hospital with a clinical history of sudden chest pain or short apnea not necessitating resuscitation. Non-invasive examinations and hemodynamic studies(More)
OBJECTIVES Arch replacement combined with antegrade stent grafting of the descending aorta represents a hybrid surgical approach for extensive thoracic aortic disease. This multicentre study evaluates the early results of this method in complex aortic dissection (AD). METHODS Retrospective data acquisition was achieved by institution of an international(More)
CardioARM, a highly flexible "snakelike" medical robotic system (Medrobotics, Raynham, MA), has been developed to allow physicians to view, access, and perform complex procedures intrapericardially on the beating heart through a single-access port. Transthoracic epicardial catheter mapping and ablation has emerged as a strategy to treat arrhythmias,(More)
We present our initial experience in 10 patients operated on using a modified Ross operation. In our modification of the Ross operation the pulmonary autograft root was inserted in the Gelweave Valsalva graft to prevent dilatation of the neoaortic root. This type of graft was selected to match the discrepancy between diameters of the annulus and the(More)
Aortic dissection occurs in Turner syndrome with substantially higher frequency in comparison to the general population, and its prevention is one of the main aims of cardiologic follow-up. Findings of cystic medial necrosis in the aortic wall and a high prevalence of aortic dilation suggest that a form of aortopathy exists in Turner syndrome. However,(More)
BACKGROUND Elevated levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) are an expected finding in many adults with congenital heart disease (ACHD) but no reports have described the range of values within different diagnostic groups. METHODS Between the years 2003 and 2011 we measured NT-proBNP in consecutive ACHD patients attending the(More)
INTRODUCTION The outcome of the operation of the Ebstein anomaly in adulthood depends on the experience of the surgical team. METHODS AND RESULTS We operated 38 adult patients with Ebstein anomaly at the age of 34.8 ± 12.7 (19-63) years at the Department of Cardiac Surgery, Hospital Na Homolce, Prague, in the period of 2005-2013. The majority of patients(More)
Uncontrolled bleeding post root, ascending aorta and aortic arch operations can occur. Various techniques for getting bleeding under control have already been published in the literature. This life-threatening complication happens especially during acute aortic dissection and acute endocarditis operations, the former sometimes requiring complex mobilization(More)
