OBJECTIVE Through a retrospective study on the use of fresh homografts in 655 aortic valve replacement patients over a period of 23 years, we aimed to assess the reasons for eventual reoperation and causes of valve dysfunction. METHODS Between January 1980 and December 2002, 655 patients received fresh homografts. All homografts were antibiotic sterilized(More)
OBJECTIVES The purpose of the study was to determine the efficacy and safety of left atrial appendage (LAA) closure via a percutaneous LAA ligation approach. BACKGROUND Embolic stroke is the most devastating consequence of atrial fibrillation. Exclusion of the LAA is believed to decrease the risk of embolic stroke. METHODS Eighty-nine patients with(More)
OBJECTIVE The ATS 3f Enable® Bioprosthesis is a self-expanding valve with a tubular design that allows for decreased leaflet stress and preservation of aortic sinuses. We report the midterm results of a prospective, multicenter clinical study evaluating the safety and efficacy of this stented bioprosthesis in patients undergoing isolated aortic valve(More)
The pathophysiologic role of the left atrial appendage (LAA) in thromboembolic disease and as the primary source for cardioembolic events in patients with atrial fibrillation (AF) has been recognized since the 1950s. This has led to the development of percutaneous approaches to exclude LAA, including LAA ligation with the LARIAT suture delivery device(More)
BACKGROUND MALT lymphomas were classified for differential diagnostics of IgG4-dependent disease due to their exceptional predilection to intraorbital localization. Therefore, the goal of our studies was large retrospective analysis of patients diagnosed with MALT lymphomas within the orbital tissues, since no such studies have been conducted in Poland. (More)
BACKGROUND Surgical ligation of the left atrial appendage (LAA) has been shown to be an effective alternative to warfarin therapy in patients with atrial fibrillation. A novel catheter-based approach for LAA ligation was evaluated for safety and effectiveness in a canine model. METHODS AND RESULTS A total of 26 healthy mongrel dogs underwent ligation of(More)
BACKGROUND The arrhythmic role of the left atrial appendage (LAA) has been implicated in the maintenance of persistent atrial fibrillation. LAA isolation with catheter ablation has been successful but is limited by the risk of tamponade and electromechanical dissociation with the potential for LAA thrombus formation. OBJECTIVE To assess whether LAA(More)
BACKGROUND The purpose of the study was to determine the efficacy and safety of left atrial appendage (LAA) closure with a micropuncture pericardial access approach and the new LARIAT(+) suture delivery device. METHODS Seventy-two patients with atrial fibrillation were enrolled to undergo telescopic micropuncture pericardial access and percutaneous(More)
OBJECTIVE Sutureless valves are designed to facilitate surgical implantation, including less-invasive techniques in aortic valve replacement, by maintaining surgical precision of implantation compared with transcatheter techniques. Long-term clinical experience with sutureless valves is lacking. We report the 5-year follow-up results of an international,(More)
BACKGROUND Atrial fibrillation is associated with an increased risk of embolic events. The left atrial appendage (LAA) is believed to be an incubator for thrombus formation. LAA exclusion has been advocated to potentially reduce embolic events arising from the LAA. OBJECTIVE The aim of the study was to determine the feasibility of a closed-chest surgical(More)
